In recent years, with the increasing requirements of users for large screen display effects, a splicing screen seamless display technology has appeared on the market. A light source compensation technology is used to achieve the seamless effect of LCD splicing, thereby removing the original The blamed physical black border problem further enhances the overall sense and provides more high-definition and complete large-screen display solutions for more high-end display occasions.
First, the technical principle
The seamless display technology of the splicing screen is improved on the basis of the original LCD splicing screen. The border part of the original LCD panel is removed through technical processes. By adding a light-emitting board composed of two rows of small-pitch LED lamps on the side, It is connected with the liquid crystal to realize the problem of light emission, and in the front position, it is encapsulated by a highly transparent polymer material, so that the entire LED part and the liquid crystal panel are stably bonded, and the overall brightness is unified under normal display conditions and restored The part that was originally blocked by the LCD frame.
Because of the limitations of the liquid crystal display technology itself, it cannot be made without a frame. Because there is a liquid crystal inside the panel and the frame is added to prevent dew, the width of the frame can only be reduced according to the continuous advancement of technology. It cannot be completely eliminated. Therefore, the splicing screen seamless technology is also a technology that realizes seamless display indirectly, which is equivalent to using the fusion principle between liquid crystal and LED to solve the problem of patchwork that bothers users.
Display effect
The picture above is a set of seamless large screens of a splicing screen installed by a company in a conference room. This compensation technology is used. Through the performance of the screen, we can clearly see that there is no black border between the entire large screens. An image is more complete, without visual obstacles, that is, the level of high-definition LCD display is achieved and the problem of LCD stitching is solved.
In the past, most of the splicing screen products were almost used in security monitoring displays, so users have not high requirements for the size of their stitching, as long as all video images can be displayed on the screen and run stably, but in recent years In recent years, more and more occasions such as conference rooms and exhibition halls have begun to use splicing screens as large-screen displays. These occasions usually display text documents, web page content, data, etc. If there is a noticeable black border, it will greatly affect Viewing experience, but users are unwilling to use LED screens due to issues such as low resolution of LEDs and other products, so major panel brand suppliers have also launched many ultra-narrow-edge products in response to this market demand, such as LG0.88mm The display effect of LCD splicing screen has been greatly improved.
Even if the stitching is small, there will be a black border, so we have introduced this splicing screen seamless display technology through years of research and development, combining LED and LCD perfectly, so as to introduce a better indoor HD display solution. It also gives users a better choice.
