Is there really no seam on the seamless screen? In the field of LCD mosaic screen, subject to the limitation of LCD technology, the LCD panel will always have a certain frame. When the whole screen is spliced and combined, it will produce obvious black frame, and the display of large screen will be affected to a certain extent. In order to better display the large screen imageSeamless splicing screenIt is very necessary.

　　1、 Technical introduction

The seamless splicing screen is based on the original LCD panel to eliminate the border through subsequent technical transformation, so as to achieve the visual unified display effect. It is not to make the LCD panel frameless. The specific method is to remove the border of the original LCD panel by technical means, and add an LED light emitting device on it. This device is composed of two rows of LED lights with small spacing, and is packaged to form a light emitting strip with a width of about 0.5 cm to cover the position above the border. The chip is connected to it and controlled to realize the simultaneous lighting of the LCD panel and the LED device. In this way, the LED part can restore the image that was originally blocked by the frame to achieve the integrated display effect.

The above figure is the basic principle diagram of seamless splicing screen. Through the technical introduction, we can know that although seamless splicing screen achieves the effect of frameless display, it is indirectly realized, using the integrated display of LCD and LED, so this is also called the electronic LED integrated seamless splicing processing technology by our company.

　　2、 Which occasions will use seamless splicing screen

In traditional applications, most of the LCD splicing screens are used in the security monitoring display, such as the monitoring center of the public security and traffic police, the monitoring room of banks and schools, etc. The requirements for splicing are not high, as long as the images of all monitoring points can be displayed at the same time, and these requirements are what the splicing screen is good at, because it can achieve segmentation, splicing and other effects on a single screen, And the resolution can match the monitored pixels perfectly.

The introduction of seamless splicing screen is mainly aimed at high-end large-screen display market, such as conference, exhibition hall, big data, financial media and other platforms. These occasions do not only pursue the display function like the monitoring room. They pay more attention to the display effect, that is, the integrity of the whole image after splicing and the user's visual experience. At this time, if there is splicing, it will have a great impact, but the resolution of the screen without splicing, such as LED technology, is insufficient, There will be mosaic phenomenon, so it is very necessary to launch a seamless mosaic screen that can achieve high definition and can display without seams.

After years of research and development, Detian Technology took the lead in launching seamless splicing technology in 2016, enabling seamless display of large screen images. Today, it has launched the third generation of seamless splicing technology, providing more solutions for many high-end large screen display user groups.
