First, you can customize the output resolution to deal with LED display physical resolution irregularities.
We all know that micro-spaced LED display by a piece of a display unit box in a matrix form of stitching, and each display unit size and physical resolution is fixed, but together with the combination of the entire screen is often not a large Standard physical resolution, for example: the display unit of the physical resolution of 128, only splicing into 1920 × 1152, the lack of spell can not spell 1920 × 1080 standard resolution. Often in a large-scale splicing system, each LED controller driven by the LED display area is also mostly not the standard resolution, this time front-end splicer with non-standard resolution output is particularly important, it can help us quickly find the right Of the splicing method, a reasonable allocation of resources, effective savings LED controller and the use of transmission equipment to increase the stability and reliability of the system, while ensuring the best display.
Second, we must ensure that the output of the synchronization, to avoid splicing screen appears not synchronized phenomenon, to ensure that no tear phenomenon.
The multi-channel DVI output signal of the splitter must have the synchronization problem of the signal. The unsynchronized DVI output signal is output to the LED display, and the picture tearing phenomenon will inevitably appear on the screen splice, especially when playing the fast moving image obvious. How to ensure that the signal output synchronization has become a measure of the success of the splicing system key.
Third, we must adopt a more high-quality image processing algorithms, so that the image after scaling to facilitate transmission and maintain high-definition.
It is well known that the image of the point-to-point image is the best, after the image is reduced, if only ordinary image processing technology or general image processing algorithm, the image brightness will drop, the edge of the image will appear serrated or even pixel missing The The face of micro-pitch LED display on the display of the harsh requirements, it is clear that the use of high-end image processing chip and a complex image processing algorithm to optimize the maximum guarantee to ensure that the image after the best display, so good The image processing algorithm is one of the key applications of the image splice to the micro pitch LED display.
