In the LCD splicing industry, since the composition of the LCD splicing screen itself must have a layer of frame to wrap the liquid crystal inside, there will be a frame of different sizes around the single LCD screen itself, resulting in a gap between the screen and the screen after the splicing. There is a significant seam. In some high-demand display venues, such as conference rooms, big data centers, integrated media centers, etc., a certain degree of hazard screens are reflected, hazard data statistics and analysis. So, can LCD splicing screens achieve seamless splicing with zero splicing? Therefore, seamless splicing screens without splicing seams are very necessary.

1. Introduction of seamless splicing technology
The seamless splicing screen is based on the original LCD panel to eliminate the frame according to subsequent technological innovations, and then achieve a visually unified display effect, instead of making the LCD panel borderless. The specific method is to remove the frame of the original LCD panel according to technical means, and add an LED light-emitting device on the top. This device is composed of two rows of small-pitch LED lights arranged and packaged to produce a width of about 0.5 cm. The position of the light-emitting strip covering the upper side of the frame is controlled according to the interconnection of the chip, so that the liquid crystal screen and the LED device part emit light together. In that way, the LED part can restore the image that was originally blocked by the frame to achieve an integrated display effect.
That is to say, the basic principle of the image of all 0mm seamless splicing screens. According to the technical introduction, we can know that although the seamless splicing screen achieves the effect of borderless display, it does it indirectly. The fusion display of liquid crystal and LED.

Second, what venues will use seamless splicing screens
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. This kind of venue does not have high requirements for splicing, as long as The images of all monitoring points can be displayed together, and this requirement is what the splicing screen is good at, because it can achieve the effects of segmentation and splicing on a single screen, and the resolution can be completely compatible with the monitored pixels. match.
The key to the introduction of seamless splicing screens is the high-end large-screen display market, such as conferences, exhibition halls, big data, integrated media and other platforms. Such venues are not like monitoring rooms that only pursue display functions. Most of them focus on display effects. That is to say, the completeness of all images after splicing and the visual experience of the customer. At this time, if there is a seam, it will be more harmful, but the resolution of a seamless screen such as LED technology is not enough, and there will be a mosaic phenomenon. Therefore, the introduction of this seamless splicing screen that can achieve high-definition and seamless display is very necessary.
