The first one; price war or technology war?
Someone asked me whether it is the price-led market or the technology-led market. In fact, this dominating battle has already begun in the field of large-screen display. When all of your peers are fighting against each other, you are eager to cut the market. While focusing on the rise of LCD splicing, we also saw the helplessness of market chaos. From a sunrise industry to today’s white-hot competition, who's helping?
In large-screen splicing systems, display devices and devices tend to be the focus of the entire system, but they do not know that the real behind-the-scenes heroes are splicing controllers; the splicing controllers directly determine the goodness and badness of the entire large-screen display. When the system often suffers from system crashes, interferences, miter cuts, frame jitter, phase shifts, and inaccurate chromatic aberrations, our engineers and users really care about the root cause of the problem. Finally, all problems are locked on the splicing controller. Only gradually paid attention to the importance of splicing the controller. At this time, it was "difficult to talk about eating berberine even though they were dumb." They had to increase a lot of budget and time to choose a control core that really belonged to the system to solve the problem. Inconvenience problem. After the builders and system integrators have been completed in the splicing of large-screen projects, it is not uncommon for them to close or fail to collect funds. This is only a moment of regret. It has to help the world's helpers and technical experts to help the world find products that meet the needs of users. Start here to save, where to simplify, a complete solution from HD to standard definition, and then to a completely unrefined system solution, in order to pursue profit, from the overall seemingly small profitable projects, and finally get a loss Do not say, but also engaged in Wen Ping screen frustrated, all soldiers are ah. Whose sins are these?
I have a little story here to share with you; in mid-November 2009, our company was holding a technical exchange meeting with Polycom South, one of the manufacturers of videoconferencing systems. Suddenly our company’s technical engineer, Wangong, rang, and hurriedly returned after half an hour, said one hundred thousand urgently; China Telecom Jiangxi's monitoring center 4X4 splicing large-screen project has “half-screen image jitter and half-screen jitter, and With a serious interference screen scrolling up and down, "the technical problems we have to come forward to help solve it, after the million workers rushed to the scene first in front of all the system analysis again, it is a cottage ah; actually used a splicing box plus LCD panel Exposed in the back, really unattractive, this does not say first; check the end of the use of VGA mode in the splicing display, first of all suffering from common problems splicing should be noted, VGA conventional resolution; 1024X768; and 4X4 large-screen physical resolution Rate: 5464 * 3072, and the conventional system is used in the entire screen splicing mode is the parent screen operation after cutting the sub-image after cutting to achieve virtual mosaic display. The VGA is an analog technology, more susceptible to external interference, and found that the length of the VGA cable is not the same, the problem of different standards have also been ignored, these details will cause the main cause of interference with the big screen." Rediscover the use of The VGA distributor is still not up to standard, and the measured bandwidth traffic is less than 100M. This is a serious failure. The VGA standard bandwidth is 350-550M/s, which is also said to be provided by the supplier. Such a company that does not understand technology and standards can actually The system was sold to large state-owned enterprises, and it was also considered to be one of the top players in the Liangshan Mountains, and Wangong first replaced the cables and distributors according to the specifications set by our company, and reorganized the system from the new one. Still accompanied by serious interference; At this time we began to suspect that the problem was caused by the hot and cold interference from the ground. The inspection of the ground wire was found to be copper wire, aluminum wire has been received a large and small thumb thick, but the detection of the control box Both the screen and the body have a large resistance, and the splice control box is actually hot, the screen is cold, and the final measurement is more than 5 ohms. The grounding is also very non-standard. According to the national standard “grounding standard shall not be greater than 2 ohmsâ€, the controller and all screens shall be connected to all grounding wires with a 16m? copper wire according to the grounding standard, standardized copper ear connectors, and the measured resistance shall be less than After 2 ohms, the boot test, all the problems were missing.
Later, it was learned that before we went there were already five companies sending technicians to solve the problem. All of them were unsuccessful. The local engineering companies were also in a quandary, like headless flies. The product supplier; is said to be helpless, the remaining 20% ​​of the estimated amount of equipment is also hopeless recovery, quietly left Jiangxi. Everyone is paying attention to technology at the same time when prices are hot. Whose crimes are these people?
In China’s electronics market, there is no shortage of “shanzhai†characters. Shanzhai not only represents low prices, unstable quality, and inaccurate workmanship, but also represents no service, no certification, no technology, and has formed a representative word for three products. Because in terms of product quality, technically there is not a lot of investment, small workshops constitute the bottom of the cost, the natural market sales price is low, the cottage-style sales model is based on the loyalty of the rivers and lakes, the interests of temptation, to earn fast way to consume The middle difference exists and it is precisely the low cost of procurement. Many engineering companies are taking advantage of high profits and many of the small business groups have built up a huge “shanzhai†product sales empire and are eroding the entire high-end display industry. chain. As the representative of the digital splicing industry, GS Electronics (China) Co., Ltd. has been positioning the mid-to-high end market, relying on new technology to make enemies and win service. We should pay attention to every detail in this troubled world and take a professional service attitude. To win this battle.
2. Development process of splicing controller Large screen splicer:
In the large-screen splicing system, we can easily focus on the splicing unit, not knowing that the real behind-the-scenes hero is the splicing controller; the splicing controller's merits directly determine the effect of the entire large-screen display system. When the application system often suffers from crashes, corruption, poor scalability, image smearing, high-definition signal chasing, miter cuts, and screen jitter, our users really care about the root cause of the problem. Finally, all problems are locked in the splicing control. On the device, it was too late.
From the controller point of view, four stitching controllers are currently available on the market. The first generation is the PCI industrial control type, the second generation is the embedded type, the third generation is the FPGA pure hardware type, and the fourth generation is the blade type digital stitching controller.
The first generation is PCI industrial control type splicing controller;
PCI card-based working principle is through the industrial computer, using multiple PCI computer motherboards, a part of the PCI slot to insert the video capture card, another part of the PCI slot to insert the video output card, input and output by the CPU to build an operation and processing Center, then built an industrial control type controller. His graphic processing principle is that the mother signal is divided into M*N sub-video signals after CPU operation, and then each sub-signal is amplified and transmitted to each corresponding unit on the mosaic wall. The display unit transmits the signal to the processor. The incoming signal is implemented on each display unit of the big screen, and the resolution and processing speed are determined by the computer CPU and the corresponding PCI card. For example, a 720P operation speed is 350MHz/nS, and 10 720P operation speed is 3.5MHz/nS. At this time, the computing power of the CPU is greatly reduced. Due to the limited computing capacity of the IPC, one has the best performance. The industrial control splicer can only realize the splicing of 4 to 4 in the case of 1024*768, which greatly limits the number of splicing units.
At the earliest, despite the introduction of a pure hardware 2*2 splicing control processor, RGB Corporation of the United States, through the cascade can also be a certain unit expansion, but the expansion ability is limited, the operation is inconvenient, the price is too expensive, popular or dual (multi) Channel output card plus computer to do splicing, and later in order to solve the problem of multi-window display, the United States COLORGRAHIC company launched multi-window multi-window splicing technology EVOLUTION control card, in order to address the window speed problem, the British Datapath company with graphics acceleration for professional video wall control Device-based multi-screen card production, RGB capture card, video switching card, the United Kingdom Datapath multi-screen card processing and control mode popular for many years, such as the year of the representative of the Speyer's stitching controller. In order to break through the PCI slot data exchange bottleneck, there has been a low-level dedicated bus switching technology to increase the data bandwidth to 8Gb/s per slot, but the first generation of PCI IPC splice controller CPU processing capacity severely restricted the stitching scale, so also The emergence of distributed processing systems, and the use of multiple processors, a common network connection, so that each processor is responsible for a small number of splicing units, and then through the network to connect the whole.
The second generation is an embedded splicing controller;
The embedded splicer is also called "in-segment splicer". It is based on the operation segmentation technology added on the LCD signal driver board. Its working principle is to transfer a complete mother screen to the signal operation processor, and the operation processor takes ID. The way of the address encoder begins to lock the position of each in the parent screen, and the operations are cut into multiple sub-images in the order of binary BCD code (BCD horizontal coordinates: from left to right, and BCD vertical coordinates: from top to bottom). The device will directly transfer the calculated data to the LCD driver board. The driver board will adjust the parameters such as color, brightness and contrast and send it to the LCDIC imager in LVDS mode to form an image. Since the embedded splicer uses hardware architecture digital graphics processing technology to process only one type of signal at a time, it does not require a powerful CPU core to operate on multi-channel signals. The simple single-screen splicing function is very flexible and convenient for customers who only need large-screen display, and was once favored by the market.
However, this internal mosaic splicer is only the processing of displaying pixels inside the unit. The result is a composite display image, which cannot solve the problem of signal high-resolution splicing and arbitrary size multi-window signal processing at any position, and more applications are displayed in single signal publicity. Screens are used in simple multi-image processing applications where cells or neighboring cells are spliced, used in high-end multi-window signal control rooms, or in conjunction with a generation of PCI industrial-control splicing controllers.
The third generation FPGA-based FPGA-based Field Programmable Gate Array (FPGA) is a field-programmable gate array. FPGAs have the high integration and versatility of gate array devices, and the user-programmable flexibility of programmable logic devices. Based on FPGA technology, the new high-speed image acquisition, through the video signal A / D conversion, DSP-based image processing technology has also been applied to give full play to the DSP hardware structure and features of programming instructions. The processing speed is improved, the processing flow of the entire image is affected due to the slow image recognition speed in the image processing process, the practical problem is solved, and good results are obtained. In the splicing system, pure hardware processor FPGA array processing architecture is adopted, full hardware design, no CPU and operating system. The controller integrates high-end image processing technologies such as ultra-wideband video signal acquisition, real-time high-resolution digital image processing, and two-dimensional high-order digital filtering, and has powerful processing capabilities. The controller uses a multi-bus parallel processing mechanism, which can fundamentally guarantee the real-time processing of all input video. The image has no delay and no discontinuity. Since the structure is beyond the design concept of the previous two generations of machines, pure Hardware processor computing technology, so start-up time, work is very stable. However, the third-generation splicing technology only stays on the 720P signal, and true high-definition and 1080P signal processing can only be daunting.
The fourth generation blade-type digital splicing controller The fourth-generation blade-type digital splicing controller developed by Gamble Electronics (China) Co., Ltd. is a digital high-definition graphics processing device based on FPGA-based hardware array technology. Scale FPGA array processing architecture and high-speed database self-built two core technologies. The blade type digital mosaic controller is different from the traditional controller; the A/D conversion performance is realized by the input module, the virtual window technology is realized by the output module, each input and output group is built into an independent operation core, and multiple computing core groups are built A powerful high-speed database, the contents of the database by the instructions sent by the control module to achieve data array output, the final output module will convert the digital signal to optical signal output.
SEEKOO blade digital splicing controller adopts independent high-speed computing technology for each channel, which greatly improves the bandwidth and computing speed. The powerful database self-built platform provides high-speed guarantee for handling multiple HD1080P ultra-high-definition dynamic signal processing. The large-scale FPGA array processing framework system provides a powerful exchange processing platform for processing ultra-high-definition and ultra-multi-type signals. The controller is also equipped with a redundant and parallel communication power supply, reserved multiple sets of backup power supply slots, 50,000 hours power-off protection function, hot-swap technology, and any expansion space of input and output modules and RS-232 local control, and at the same time can be achieved Multiple processors in the TCP/IP remote unified interface management and control functions, and many other core technologies have become leaders in the field of digital splicing.
In the liquid crystal splicing industry, most manufacturers still stay on the technology of solving analog signals. Some manufacturers have already begun to solve digital high-definition technologies. Then who will solve a complete set of high-definition display systems? SEEKOO is striving to create a perfect vision, guide and promote the industry to stride forward and development is a corporate responsibility;
As a liquid crystal display technology with high-definition, high-efficiency, high-life, high-brightness and other advantages, has already won the top spot in the display field has no doubt. In the large-screen display system, the display unit is used as the final display carrier. It is whether the entire system is equipped with superiority, and whether the processing technology is highly effective is presented before us. However, clutter interference and skew often occur in a large part of large-screen projects. When cutting, screen jitter, phase shifts, and inaccurate chromatic aberrations were all problems, engineers began to shirk their problems and investigate the problems there. Eventually, they couldn't stop them.
SEEKOO stride forward technical director Wan total thinks: First, the anti-jamming technology of the processing equipment itself is not closed, the second is the external magnetic field and clutter interference in the transmission process, and the third is the color difference caused by different display levels, and the fourth is A/D, The performance deviation rate produced by the D/A conversion operation creates a tricky “golden square†problem. Wan Zong also said that if you want to completely change the "golden square" problem in large-screen splicing display systems, that is to digitalize the system, then both the incoming analog signals and digital signals at the front end will all be converted into digital signals to the optical fiber. Digitally transmitted to the display, but currently there is no optical interface on the market. Under normal circumstances, it is converted to analog/digital (VGA or DVI) J interface to display, so that a lot of analog devices turn around Going also greatly increases the cost and complexity of the system, and at the same time it also brings sequelae for the after-sales.
The simplification of the system means that the simplicity of operation and the simplification of connections are the consistent tenet of SEEKOO. SEEKOO is striving to create a perfect digital vision, and guiding and promoting the advancement of the industry is a swift and never-changing pursuit; SEEKOO's latest research and development The DS series optical fiber display unit breaks the convention and introduces the optical fiber technology into the splicing display. The truly digital splicing unit and the digital splicing unit not only solve the problem of poor anti-interference of the analog signal, but also break the traditional analog/digital transmission at close range. Malady. The birth of new technology for digital splicing and display unit will represent the digital signal can be implemented consistently.

Broadband Electronics (China) Electronics Co., Ltd. has become the king in large-screen splicing systems with many core products such as blade-type digital splicing controllers and optical fiber digital displays. It will also be the guide for future display fields! We fully believe that SEEKOO is the trend-maker and leader in the field of digital splicing. Let us witness this moment of time.
3. The fourth generation of blade-type digital splicing will be the leader in the field of splicing. SEEKOO Kobun Electronics (China) Co., Ltd. relies on the national 863 project team technology platform, adhering to the business philosophy of winning attention to detail and technology, and has established itself with numerous core technologies. Digital splicing leadership. At the same time, it is also the first domestic manufacturer to implement optical fiber technology concerns for the entire large-screen system. The first company produced a splicing unit with an optical fiber interface and the first manufacturer to use a production blade-type digital processor.
When all front-end equipment manufacturers are concerned about digital high-definition, promote H. 264, 1080P, super map, special sub-map at the same time, and many companies have ignored a problem, high-definition display technology has come; then who is concerned about digital high-definition image processing technology?
The large-screen video wall has always been one of the products with high technical content and high output efficiency in the display field. It has insurmountable technical barriers for ordinary enterprises. This is destined to splicing products to lead the development of display technology, but also brings the company Great returns and more say. Therefore, the ability to develop videowall products with leading technologies has often become the best indicator of establishing the status of manufacturers in the display industry.
Controversy over technology The white-hot industry is facing reshuffle. Currently, in the field of large-screen splicing, DLP, PDP, and LCD have taken advantage of their respective advantages, occupying unequal market shares, and presenting the situation in the same world. As the pioneer in the field of large-screen splicing, the DLP monitor first entered this battlefield and occupied half of the entire market. However, DLP displays have not been able to achieve effective breakthroughs because of their high power consumption and their large footprint. Although plasma products have made certain progress in image quality, the problems that cause users to suffer headaches and congenital defects in their lives have also greatly restricted the development and popularization of PDP products.
With the advent of LCD splicing products, the big screen splicing market has undergone tremendous changes. LCD products are quickly recognized by many users for their high definition, wide viewing angle, high brightness and long life. Compared with DLP and PDP, DLP has a long service life, low power, low heat, and low failure rate. The dynamic display life of the PDP may reach tens of thousands of hours, but it may be 5,000 hours when displaying high-brightness static images. Therefore, most engineers recommend such items as security monitoring large-screen videowalls that require 24 hours of continuous use. The choice should be chosen as much as possible to choose the LCD splicing curtain wall in order to improve the efficiency of use, reduce the use of cost and maintenance costs.
However, due to the splicing gap that cannot be avoided during the splicing process of the liquid crystal splicing products, the bottleneck that is difficult to break through is encountered in the process of popularization. Therefore, it has been predicted that once the liquid crystal splicing is turned on seamlessly, the display area will fully enter the era of liquid crystal.
Liquid crystal splicing seamlessly leads the new era In 2009, the introduction of the seamless liquid crystal splicing screen of the SEEKOOVIP ultra-narrow-edge project series made this prediction a reality. Broadband Electronics (China) Co., Ltd., as a well-known display manufacturer, not only accumulated rich experience in LCD production, but also made remarkable achievements in the R&D field. The launch of the VIP ultra-narrow-edge engineering product series is based on striding deep technical accumulation, successfully achieved a breakthrough in seamless, high-definition dual technology, the LCD splicing formally brought into a seamless era.
In order to ensure the best image quality, SEEKOOVIP's ultra-narrow-edge seamless liquid crystal splicing screen has been specially adopted in the 1920*1080 HD standard and is being presented in detail. In addition, the unique DID panel technology of SEEKOO further enhances the brightness of its screen to 700nits, providing viewers with a bright and vivid picture display effect.
In addition, the use of SEEKOO's second-generation building block interconnection technology has also made stitching easier and more convenient. Users can easily complete the splicing of the LCD screen like building blocks, and can also realize multi-shape, multi-angle, and multi-functional three-dimensional splicing according to demand, free from the traditional flat matrix splicing method, and make the splicing effect more flexible, and in a limited way. The best image display is achieved in space, giving viewers more powerful visual impact.
At the same time, the application of SEEKOO ultra-high definition image management system also effectively reduces the video wall operating costs. As we all know, the splicing screen is only one of the splicing units of the video wall. In order to complete the splicing, the traditional splicing method also requires the user to purchase the corresponding auxiliary splicing and provisioning, which also adds a considerable financial burden to the user, and SEEKOOVIP super The narrow-side engineering series products can be connected by using only one network cable through the built-in module, without purchasing additional hardware equipment, completely eliminating the dependence of the traditional large-screen splicing system on the central processor. Not only does it make splicing easier, it also saves users a lot of operating costs.
Someone asked me whether it is the price-led market or the technology-led market. In fact, this dominating battle has already begun in the field of large-screen display. When all of your peers are fighting against each other, you are eager to cut the market. While focusing on the rise of LCD splicing, we also saw the helplessness of market chaos.

In the liquid crystal splicing industry, most manufacturers still stay on the technology of solving analog signals. Some manufacturers have already begun to solve digital high-definition technologies. Then who will solve a complete set of high-definition display systems? SEEKOO is striving to create a perfect vision, guide and promote the industry to stride forward and development is a corporate responsibility;
As a liquid crystal display technology with high-definition, high-efficiency, high-life, high-brightness and other advantages, has already won the top spot in the display field has no doubt. In the large-screen display system, the display unit is used as the final display carrier. It is whether the entire system is equipped with superiority, and whether the processing technology is highly effective is presented before us. However, clutter interference and skew often occur in a large part of large-screen projects. When cutting, screen jitter, phase shifts, and inaccurate chromatic aberrations were all problems, engineers began to shirk their problems and investigate the problems there. Eventually, they couldn't stop them.
SEEKOO stride forward technical director Wan total thinks: First, the anti-jamming technology of the processing equipment itself is not closed, the second is the external magnetic field and clutter interference in the transmission process, and the third is the color difference caused by different display levels, and the fourth is A/D, The performance deviation rate produced by the D/A conversion operation creates a tricky “golden square†problem. Wan Zong also said that if you want to completely change the "golden square" problem in large-screen splicing display systems, that is to digitalize the system, then both the incoming analog signals and digital signals at the front end will all be converted into digital signals to the optical fiber. Digitally transmitted to the display, but currently there is no optical interface on the market. Under normal circumstances, it is converted to analog/digital (VGA or DVI) J interface to display, so that a lot of analog devices turn around Going also greatly increases the cost and complexity of the system, and at the same time it also brings sequelae for the after-sales.
The simplification of the system means that the simplicity of operation and the simplification of connections are the consistent tenet of SEEKOO. SEEKOO is striving to create a perfect digital vision, and guiding and promoting the advancement of the industry is a swift and never-changing pursuit; SEEKOO's latest research and development The DS series optical fiber display unit breaks the convention and introduces the optical fiber technology into the splicing display. The truly digital splicing unit and the digital splicing unit not only solve the problem of poor anti-interference of the analog signal, but also break the traditional analog/digital transmission at close range. Malady. The birth of new technology for digital splicing and display unit will represent the digital signal can be implemented consistently.

Broadband Electronics (China) Electronics Co., Ltd. has become the king in large-screen splicing systems with many core products such as blade-type digital splicing controllers and optical fiber digital displays. It will also be the guide for future display fields! We fully believe that SEEKOO is the trend-maker and leader in the field of digital splicing. Let us witness this moment of time.
3. The fourth generation of blade-type digital splicing will be the leader in the field of splicing. SEEKOO Kobun Electronics (China) Co., Ltd. relies on the national 863 project team technology platform, adhering to the business philosophy of winning attention to detail and technology, and has established itself with numerous core technologies. Digital splicing leadership. At the same time, it is also the first domestic manufacturer to implement optical fiber technology concerns for the entire large-screen system. The first company produced a splicing unit with an optical fiber interface and the first manufacturer to use a production blade-type digital processor.
When all front-end equipment manufacturers are concerned about digital high-definition, promote H. 264, 1080P, super map, special sub-map at the same time, and many companies have ignored a problem, high-definition display technology has come; then who is concerned about digital high-definition image processing technology?
The large-screen video wall has always been one of the products with high technical content and high output efficiency in the display field. It has insurmountable technical barriers for ordinary enterprises. This is destined to splicing products to lead the development of display technology, but also brings the company Great returns and more say. Therefore, the ability to develop videowall products with leading technologies has often become the best indicator of establishing the status of manufacturers in the display industry.
Controversy over technology The white-hot industry is facing reshuffle. Currently, in the field of large-screen splicing, DLP, PDP, and LCD have taken advantage of their respective advantages, occupying unequal market shares, and presenting the situation in the same world. As the pioneer in the field of large-screen splicing, the DLP monitor first entered this battlefield and occupied half of the entire market. However, DLP displays have not been able to achieve effective breakthroughs because of their high power consumption and their large footprint. Although plasma products have made certain progress in image quality, the problems that cause users to suffer headaches and congenital defects in their lives have also greatly restricted the development and popularization of PDP products.
With the advent of LCD splicing products, the big screen splicing market has undergone tremendous changes. LCD products are quickly recognized by many users for their high definition, wide viewing angle, high brightness and long life. Compared with DLP and PDP, DLP has a long service life, low power, low heat, and low failure rate. The dynamic display life of the PDP may reach tens of thousands of hours, but it may be 5,000 hours when displaying high-brightness static images. Therefore, most engineers recommend such items as security monitoring large-screen videowalls that require 24 hours of continuous use. The choice should be chosen as much as possible to choose the LCD splicing curtain wall in order to improve the efficiency of use, reduce the use of cost and maintenance costs.
However, due to the splicing gap that cannot be avoided during the splicing process of the liquid crystal splicing products, the bottleneck that is difficult to break through is encountered in the process of popularization. Therefore, it has been predicted that once the liquid crystal splicing is turned on seamlessly, the display area will fully enter the era of liquid crystal.
Liquid crystal splicing seamlessly leads the new era In 2009, the introduction of the seamless liquid crystal splicing screen of the SEEKOOVIP ultra-narrow-edge project series made this prediction a reality. Broadband Electronics (China) Co., Ltd., as a well-known display manufacturer, not only accumulated rich experience in LCD production, but also made remarkable achievements in the R&D field. The launch of the VIP ultra-narrow-edge engineering product series is based on striding deep technical accumulation, successfully achieved a breakthrough in seamless, high-definition dual technology, the LCD splicing formally brought into a seamless era.
In order to ensure the best image quality, SEEKOOVIP's ultra-narrow-edge seamless liquid crystal splicing screen has been specially adopted in the 1920*1080 HD standard and is being presented in detail. In addition, the unique DID panel technology of SEEKOO further enhances the brightness of its screen to 700nits, providing viewers with a bright and vivid picture display effect.
In addition, the use of SEEKOO's second-generation building block interconnection technology has also made stitching easier and more convenient. Users can easily complete the splicing of the LCD screen like building blocks, and can also realize multi-shape, multi-angle, and multi-functional three-dimensional splicing according to demand, free from the traditional flat matrix splicing method, and make the splicing effect more flexible, and in a limited way. The best image display is achieved in space, giving viewers more powerful visual impact.
At the same time, the application of SEEKOO ultra-high definition image management system also effectively reduces the video wall operating costs. As we all know, the splicing screen is only one of the splicing units of the video wall. In order to complete the splicing, the traditional splicing method also requires the user to purchase the corresponding auxiliary splicing and provisioning, which also adds a considerable financial burden to the user, and SEEKOOVIP super The narrow-side engineering series products can be connected by using only one network cable through the built-in module, without purchasing additional hardware equipment, completely eliminating the dependence of the traditional large-screen splicing system on the central processor. Not only does it make splicing easier, it also saves users a lot of operating costs.
The color of the dimmable Smart Film can be customized, like white, gray, red, blue, orange, green, blue, etc.
Tinted film is suitable for use in dry environment, personnel stable places, such as offices, personal residence, etc., are a good choice of application. But the personnel complex public places, such as hotels, shopping malls, etc., is not recommended, because the dimming decorative film is stuck on the glass surface, easy to cause people's curiosity and unpredictable damage.
Adjust the glass shading coefficient can be adjusted, but also with the change of conditions, the glass can be adjusted to the transparent and opaque state, so as to ensure the indoor temperature: summer, to ensure that you can avoid sunlight, opaque state it can also reflect most of the harmful light; And in winter, it keeps warm, eliminates cold and prevents heat from escaping indoors.
The use of ordinary single glass doors and Windows, hot and cold overflow fast, large energy consumption, waste of cost, installation of dimming glass, can improve the indoor temperature, reduce heating and cooling costs, reduce energy costs for customers.
