Multi-source tiled display system and display screen gap aberration eliminating method

Abstract

The invention discloses a multi-source tiled display system and a display screen gap aberration eliminating method. The multi-source tiled display system comprises a synchronization master machine, and a plurality of display units. Each display unit comprises a slave machine and a display screen driven by the slave machine. The slave machine is connected with the synchronization master machine through a network cable. The synchronization master machine sends a synchronization signal through the network cable to coordinate the playing progress of all of the slave machines. Each display unit comprises an image processing unit. The input end of the image processing unit is connected with the slave machine, and the output end of the image processing unit is connected with the display screen to form data transmission channels from the slave machine to display screen. Adjacent image processing units are interconnected. The image processing unit is used to perform superposition on a received transition zone signal of an adjacent channel and a transition zone signal of the present channel to realize image edge fusion. According to the invention, by generating an image transition zone on circuit hardware, the image edges are fused, so gap aberration can be effectively eliminated visually to realize moving image gap no-aberration display.

Description

[technical field] [0001] The invention relates to a multi-source splicing display screen, in particular to a multi-source splicing display system and a method for eliminating aberrations between screen gaps. [Background technique] [0002] With the development of splicing display screens, there is a further demand for the source of ultra-high-resolution images. A single player can no longer decode, play and transmit such ultra-high-resolution images. Studio system, which divides a set of images into different blocks, decodes and plays them separately on multiple players, and drives the corresponding areas of the splicing display at the same time. This method of dividing an image into multiple signal sources for display is called It is a multi-source splicing system. figure 1 It is a schematic block diagram of a multi-source splicing system. The synchronization mechanism of its playback comes from the network connection. A host sends a synchronization signal through a networ...

Problems solved by technology

[0005] However, for dot-matrix light-emitting splicing display systems, such as LED and LCD display systems, since there is no optical space fusion condition, the aberration of adjacent display devices will appear, which seriously affects the quality of the splicing display.
