Point-to-point display scenarios.
Splicing screen point-to-point refers to the signal source image of each pixel can correspond to a pixel of the splicing screen display, usually used in the case of high-definition resolution display requirements, for example, we have a ** is 4k, want to be able to maintain the 4K display effect when displayed on the splicing screen, then you need to use a point-to-point solution.
Because if you install it with an ordinary scheme, even if we are more than 4 splicing screens, the effect it displays is still 2K, which is an ordinary 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 cannot be reached, it is still displayed 1920* 1080 effect, so we often have a feeling that no matter how many pieces of the splicing screen are spliced, how large the physical resolution is, the image will feel very blurry when displaying the content of the computer screen.
For example, a 4K **,What is displayed through the conventional 4 splicing large screens is actually 2K effect,Because the controller and transmission line used in the conventional splicing screen are 2K,Even if its 4 screens can reach 4K physical resolution after splicing,But the displayed effect is still 2K。
Under normal circumstances, no matter how large the physical resolution of the display product is, it is actually displayed with a 2K effect, even if the **source is4K, or 8K, the original clarity cannot be displayed. In addition to the requirements of 4K** or 3D effect, they also want to achieve high-definition effects when displaying web pages, documents and other files, so it is necessary to design a point-to-point display scheme in a targeted manner, which needs to be changed from both software and hardware.
Point-to-point splicing large-screen display scheme.
1. Change the way the control system adds high-definition cables.
The control of the splicing large screen display is the splicing controller, the conventional splicing screen controllers are 2K, no customization is required, now the most used in the market is a kind of splicing controller that can achieve point-to-point control, a single support 4K resolution, can control the resolution of the vertical part within 4K, it can also be horizontal splicing 4K, the number of controllers can be determined according to the number of splicing large screens, and the maximum can support 16K resolution point-to-point display.
In addition, the high-definition cable used for transmission between the signal source and the splicing large screen should also be replaced with 4K, and the graphics card on the output computer side should also be highly configured, and a separate control software is required at the same time, such as a big data system based on web page development on the computer, after this scheme is projected on the large screen, the entire web page content is full HD, and a pixel corresponds to a pixel of a large screen, and the definition is very high.
Second, it is realized through an external processor.
If you don't want to change the original splicing screen and control system, you can add an external splicing processor in the middle of this system, this processor supports more than 4K resolution display, through the software and the software of the large screen to achieve compatibility and point-to-point through the host console, this scheme is relatively simple, only need to add a device and software, thanks to the internal integrated chip, and at the same time can also achieve more splicing functions.
When we ask the customer's needs in the early stage of the project, the customer needs to splice the large-screen high-definition display or ultra-high-definition display, at this time, if you want to achieve point-to-point high-definition display, you must use the point-to-point splicing scheme.
At present, most of the point-to-point splicing solutions commonly used in the market use a point-to-point high-definition processor that combines software and hardware, and TA is equipped with its own unique software to achieve point-to-point display requirements, and can achieve up to 8K display effect. This high-definition processor is like an external splicing processor, it is also composed of two parts, input and output, the input end is connected to a computer, this computer only needs a conventional computer, 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 screens within 8K resolution display, for example, we are 4*4, 16 splicing screen display, then the resolution of the splicing screen has reached 7680* 4320, which is 8k, so that the effect of point-to-point display is achieved. "
In addition to point-to-point, Winbond can also achieve non-deformation display by equipping it with a high-definition processor, that is, when the number of rows and columns on the splicing screen is inconsistent, the image can still maintain a 16:9 effect after being projected onto the splicing screen. For example, in the case of multiple columns in a row, the displayed image will be stretched under normal circumstances, but with this device, the normal scale can be maintained without distortion.
This high-definition point-to-point solution is mostly used in some exhibition occasions, such as enterprise exhibition halls, big data publicity and other fields, these fields have very high requirements for the resolution of the splicing screen, especially some systems based on web development, in order to achieve a better visual experience, point-to-point display is particularly important.
At present, huabangying LCD splicing screen point-to-point has been widely used in a variety of big data and exhibition halls and other occasions, in today's 4K and 8K signal sources continue to popularize, display products are also gradually upgraded, not only display function diversification, followed by more attention to the user's visual experience.
