Does the seamless splicing screen really have no seams? In the field of LCD splicing screens, limited by the liquid crystal technology, the LCD panel will always have a certain frame. When the entire screen is spliced and combined, it will produce an obvious black frame, and the display of the large screen will be affected to a certain extent. In order to better display the large-screen images, it is very necessary to introduce seamless splicing screens.
1. Technical introduction
The seamless splicing screen is based on the original LCD panel through subsequent technical transformation to achieve the elimination of the frame, so as to achieve the effect of visually unified display, instead of making the LCD panel borderless. The specific method is to remove the frame of the original LCD panel through technical means, and add an LED light-emitting device on it. This device is composed of two rows of small-pitch LED lights arranged and packaged to form a light-emitting strip with a width of about 0.5 cm. At the position above the frame, the chip is connected to the control to realize the simultaneous light emission of the liquid crystal screen and the LED device part. In this way, the LED part can restore the image that was originally blocked by the frame to achieve an integrated display effect.
The figure above is an illustration of the basic principle of seamless splicing screen imaging. Through technical introduction, we can know that although seamless splicing screen achieves the effect of borderless display, it is realized indirectly, using LCD and LED fusion display, so this is also called electronic LED fusion seamless splicing processing technology by our company.
Second, what occasions will the seamless splicing screen be used?
In traditional applications, most LCD splicing screens are used in security monitoring and display, such as the monitoring center of public security traffic police, the monitoring room of banks and schools, etc. These occasions have low requirements for splicing, as long as they can The images of all monitoring points can be displayed at the same time, and these requirements are exactly what the splicing screen is good at, because it can realize the effects of segmentation and splicing on a single screen, and the resolution can be perfectly matched with the monitored pixels.
The introduction of seamless splicing screens is mainly for the high-end large-screen display market, such as conferences, exhibition halls, big data, integrated media and other platforms. These occasions are not like monitoring rooms that only pursue display functions. They focus more on display effects. That is to say, the completeness of the entire image after stitching and the user's visual experience. At this time, if there is a seam, it will have a greater impact, but the resolution of a seamless screen such as LED technology is insufficient, and there will be mosaic phenomenon, so It is very necessary to launch a seamless splicing screen that can achieve high-definition and can display without splicing at the same time.
