In recent years, a seamless LCD splicing screen technology that can achieve 0mm black edge free display 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 was mass-produced in the second year. As of now, this technology has developed to the second generation, and it can be said that 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's a technical principle.

　　1、 Market Status and Background

In the past, large screen products were mainly used in specific occasions, such as government command and dispatch centers, public security and traffic police command and monitoring centers, commercial advertising screens, and so on. The products are basically two types: LED and LCD, and LCD is mostly used as a monitoring display device, so the requirements for display effect are not so high.

With the increasing demand for more meetings, exhibition halls, data displays, and other occasions, LCD splicing products have also been applied. However, what is reflected is that its splicing problem seriously affects its market development. More and more users are paying attention to both high-definition screens and visual experience, so the splicing problem is seriously magnified, which has become the fundamental reason why 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 using small pitch LED and LCD to fuse and achieve the effect of eliminating borders.

The specific structure is based on the original 55 inch LCD splicing screen, and a specially developed LED light compensation chip is added to the side of the screen, and packaged with a lens. This way, the entire LCD screen and LED can emit light simultaneously. When playing images, the LED light source compensation technology can restore the parts that were originally blocked by black edges, achieving the effect of eliminating borders and displaying the entire screen.

Since the birth of seamless LCD splicing screen technology, it has been widely used in fields such as video conferencing and big data display platforms. Based on user feedback in the past two years, seamless LCD splicing screens have achieved 1920 * 1080 or even 4K display, and there is no stitching yet. The price is also more favorable than LED small spacing, so it has become the best solution for large screen display in conference rooms.

We all know that the splicing problem of LCD splicing screens has existed for a long time, and current technology is not enough to fundamentally remove it, so we can only try to reduce it as much as possible. Although our company has also launched a 0.88mm LCD splicing screen, the display effect is still not comparable to small pitch LED. The introduction of seamless LCD splicing screen technology makes it convenient to fill the weakest link of LCD splicing technology, thus simultaneously combining the common characteristics of LCD and LED display technologies.
