With the continuous advancement of liquid crystal splicing technology, the thickness of large screen splicing is also getting thinner and thinner. The thickness of the product is thinner, and in addition to reducing weight, being more beautiful, and being more convenient to install, it also has the effect of speeding up response time. In addition to reducing the thickness, the method of shortening the response time of the large-screen splicing also increases the driving voltage.
According to the latest research results and research data, if the thickness of the spliced ​​large screen is reduced by 20, the response speed will increase by 35 on the original basis. From this we can know that the reduction of the thickness of the spliced ​​large screen is very large for the large screen of the LCD splicing. But shortening the response time will also bring a series of negative effects to the big screen. The thickness is too thin, which increases the difficulty in manufacturing, and makes the color of the screen display dim, and also makes the viewing angle smaller. In addition to these, there is a possibility that the probability of occurrence of a dead pixel on the screen increases, and the yield of the product is lowered. From a manufacturer's point of view, the manufacturing cost will also increase a lot. Therefore, in order to reduce the thickness of the large screen, there are still many difficulties, and there is currently no perfect technology to solve this problem.
Some researchers have thought about improving the driving voltage of the DID LCD splicing screen system to shorten the response time. The research results show that as long as the driving voltage is doubled to the original base, the response time can be shortened from 50ms to 5ms. Of course, this method also has a certain negative impact. The splicing large screen is composed of a liquid crystal panel, and the increased voltage will form an overshoot voltage, which will increase the difficulty of returning the liquid crystal, which leads to a prolongation of the fall time and the gray-scale response time. Moreover, excessive compensation can also cause certain hazards, which can cause serious distortion of the image displayed on the screen. What's more, the overshoot voltage will not only lead to a decrease in gray scale, but also shorten the life of the spliced ​​large screen. So from the current technology point of view, this technology is not very mature, and can not be used in practice.
Although the technology for shortening the response time of splicing large screens is not too mature, there are still many drawbacks, but with the continuous advancement of technology, it is believed that the response time will be shorter and shorter, and the product functions will be more and more perfect.
