What is a 4K high-definition LCD splicing screen.HD LED display screen modules

　　In the 4K high-definition LCD splicing screen, 4K refers to the resolution, which is 3840 x 2160 (horizontal pixels x vertical pixels), and 4096x2160. The 4K resolution is four times higher than the traditional 1080P display clarity. In some indoor meeting rooms and display occasions, high-definition LCD splicing screens have become a major standard requirement for users, because it is often necessary to play 4K high-definition videos, big data and other content. In this case, if a conventional LCD splicing screen is used, the displayed resolution effect is actually 2K. To achieve a resolution display effect of 4K or above, it needs to be customized separately.

　　Traditionally, the resolution of LCD splicing screens can be stacked. After splicing four screens, the resolution is 1920 * 2 in length and 1080 * 2 in width, which is 3840 * 2160, which is the 4K standard for display. But this is only a physical parameter. In fact, in determining whether a signal source can achieve high-definition display effects, in addition to the resolution requirements on the display end, it is also required that the output end, transmission end, etc. must achieve high-definition resolution. At this point, let's first look at the output display end. The so-called high-definition LCD splicing screen is actually composed of small screens pieced together. The resolution of four screens is 4K, and after 4 * 4 splicing, it can reach 8K. According to the Windows system display standard, it can support up to 16K resolution display. Therefore, we want to achieve a higher resolution by stacking LCD splicing screens. But these alone are not enough. A high-definition splicing processor is also needed to control, which determines the interconnection between LCD splicing screens. The computer side controls the resolution of the output signal. In addition to customized videos, such as outputting content on web pages, in order to achieve a 4K or higher effect, it is also necessary to customize the computer configuration, especially the graphics card needs to be compatible with the splicing processor of the LCD splicing screen to achieve software compatibility. Moreover, the high-definition transmission line also needs to support 4K, which is relatively easy to meet.
