Point-to-point display scheme
Splicing screen point-to-point refers to that each pixel of the signal source image can correspond to a pixel display of the splicing screen, usually used in the case of high-definition resolution display needs, such as we have a video is 4K, want to display on the splicing screen can still maintain 4K display effect, then you need to use a point-to-point scheme.
Because if it is installed with an ordinary scheme, even if we are more than 4 pieces of splicing screen, the effect it displays is still 2K, which is a common sense, because even if the signal source reaches 4K, the resolution of the splicing screen is 1920*1080, but because the signal transmission and control system can not reach. So it still shows the effect of 1920*1080, so we often have a feeling that no matter how many pieces of splicing screen splicing, how much physical resolution is, when displaying the content of the computer projection screen, the image will feel very fuzzy.
For example, a 4K video, through the conventional 4 pieces of splicing screen display is actually 2K effect, because the conventional splicing screen controller and transmission line are 2K, even if its 4 pieces of screen splicing physical resolution can reach 4K, but the display effect is still 2K.
Under normal circumstances, no matter how big the physical resolution of the display product is, the effect is actually 2K, even if the video source is 4K, or 8K, it can not show the original clarity. In some enterprise exhibition halls or big data display occasions, users have higher requirements for the clarity of the screen, in addition to 4K video or 3D effect requirements, in the display of web pages, documents and other files also want to achieve high-definition effects, then you need to design a point-to-point display scheme, which needs to change from two aspects of software and hardware.

Point-to-point splicing large-screen display scheme
1. Change the way the control system adds high-definition lines
Control splicing large screen display is splicing controller, the conventional splicing screen controller is 2K, no need to customize, the most widely used on the market is a splicing controller that can achieve point-to-point control, a single support 4K resolution, can control the resolution of the vertical column within 4K, can also be a horizontal splicing 4K, The number of controllers can be determined according to the number of splicing large screens, which can support a maximum of 16K resolution point-to-point display.
In addition, the HD line used for transmission between the signal source and the splicing screen should also be replaced with 4K, the graphics card of the output computer should also be highly configured, and a separate control software is required, such as a big data system based on web development on the computer, after throwing this solution to the large screen, the entire web content is full HD. A pixel corresponds to a large screen pixel, the clarity is very high.
2, through the external processor
If you do not want to change the original splicing screen and control system, you can add an external splicing processor in the middle of the system, the processor supports more than 4K resolution display, compatible with the software of the large screen and point-to-point through the host console, this solution is relatively simple, only need to add a device and software can be. This is thanks to the integrated chip inside, while also enabling more splicing functions.
When we ask the customer's needs in the early stage of the project, the customer needs to splice a large screen high-definition display or ultra-high-definition display, at this time to achieve point-to-point high-definition display, it is necessary to use a point-to-point splicing solution.
Most of the point-to-point splicing solutions commonly used in the market now use a point-to-point HD processor that combines hardware and software, Ta with its own unique software to achieve point-to-point display needs, and can achieve up to 8K display effects. This HD processor is like an external splicing processor, it is also composed of input and output two parts, the input is connected to a computer, the computer only needs a conventional computer on the line, used as the output device of the signal source, and then its output is connected to each splicing screen, through its control can achieve 36 splicing screen within 8K resolution display. For example, we are 4*4, 16 splicing screen display, then the resolution of the splicing screen reached 7680*4320, that is, 8K, so as to achieve the effect of point-to-point display.
In addition to point-to-point, through this HD processor can also achieve non-deformation display, that is, the number of rows and columns of the splicing screen is inconsistent, the image can still maintain a 16:9 effect after being cast on the splicing screen. For example, in the case of multiple columns, the image displayed under normal circumstances will be stretched, and through this device, the normal proportion can be maintained without deformation.
This high-count point-to-point solution is often used in some exhibition and display occasions, such as enterprise exhibition halls, big data publicity and other fields, which have very high requirements for the resolution of the splintered screen, especially for some web-based development systems, in order to achieve a better visual experience, point-to-point display is particularly important.
Of course, this HD processor in addition to point-to-point and no deformation of the two major functions, it can also achieve a single screen screen segmentation display, cross-screen splicing display and other functions, equivalent to an external processor, very powerful.
At present, this point-to-point splitter screen has been widely used in a variety of big data and exhibition halls and other occasions, in the 4K and 8K signal sources are increasingly popular today, display products are gradually upgraded, not only the diversification of display functions, followed by more attention to the user's visual experience.
