In recent years, a seamless LCD mosaic screen technology that can achieve 0mm display without black edge has emerged in the large-screen display market. This technology was first proposed by our company in 2015, and the first generation of 55-inch products were mass produced in the second year. Up to now, this technology has developed to the second generation. It can be said that the seamless LCD splicing screen display technology has become a very mature product. However, due to various principles, we have very little contact with users. Today we will explain in detail0mm seamless LCD splicing screenIt is the technical principle.

　　1、 Market status and background

In the past, large-screen products were mainly used in specific occasions, such as the government's command and control center, the police's command and control center, and commercial advertising screens. The products are basically LED and LCD, and most of them are used as monitoring display devices, so the requirements for display effect are not so high.

As the demand for more meetings, exhibition halls, data displays and other occasions continues to rise, LCD splicing products have also begun to be applied, but what is reflected is that its stitching problem has seriously affected its market development. More and more users pay more attention to both the high-definition of the screen and the visual perception, so the stitching problem has been seriously magnified, which has also become the fundamental reason why the seamless LCD splicing screen technology was first proposed.

　　2、 Principle of seamless splicing technology

The seamless LCD splicing screen technology launched by our company is a light source compensation technology. Specifically, it uses small spacing LED to fuse with LCD to achieve the effect of eliminating the border.

The specific structure is that on the basis of the original 55-inch LCD mosaic screen, a specially developed LED light compensation chip is added to the side of the screen, and the lens is used for packaging, so that the entire LCD screen and LED can emit light at the same time. When playing the image, through the LED light source compensation technology, the original part covered by the black edge can be restored, so as to achieve the effect of eliminating the border and the whole screen display.

Since the birth of the seamless LCD mosaic screen technology, it has been widely used in fields such as video conference, big data display platform, etc. According to user feedback in the past two years, the seamless LCD mosaic screen has achieved 1920 * 1080 or even 4K display, and there is no seam. The price is also more favorable than the LED small spacing, so it has become the best solution for large screen display in the conference room.

As we all know, the splicing problem of LCD splicing screen has existed for a long time, and the current technology is not enough to eliminate it fundamentally, so we can only reduce it as much as possible. Although our company has also introduced 0.88mm LCD splicing screen, the display effect is still not comparable with the small-space LED, and the introduction of seamless LCD splicing screen technology, which facilitates the most weak link of LCD splicing technology, has been supplemented, Thus, it combines the common characteristics of LCD and LED display technologies.
