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.

Embodiment Construction

[0028] The basic idea of ​​the present invention is to perform edge blending on signals of adjacent sources in advance to eliminate aberrations caused by asynchronous picture timing and content. The aberrations of adjacent sources at the seam can be spatially diffused after fusion, and the aberrations are uniformly dispersed in a relatively wide range to eliminate the sudden change of the human eye at the seam and the aberration between adjacent pixels sensitive. The fusion effect of the same principle has been verified in a large number of projection splicing and fusion systems. The difference is that the projection system adopts spatial optical edge fusion. The present invention uses edge fusion for signal content, which is suitable for dot matrix light-emitting splicing displayed in the system.

[0029] Such as image 3 As shown, the multi-source splicing display system of the embodiment of the present invention includes a synchronous master and multiple display units, ea...

Abstract

The invention discloses a multi-source splicing display system and a method for eliminating aberrations between display screen slits. The multi-source splicing display system includes a synchronous host and a plurality of display units. The display unit includes a slave and a display driven by the slave. The slave is connected to the sync host through a network cable, and the sync master sends a synchronization signal through a network cable to coordinate all slaves. The display unit includes an image processing unit, the input terminal of the image processing unit is connected to the slave machine, and the output terminal is connected to the display screen to form a channel for transmitting data from the machine to the display screen; adjacent image processing units are interconnected, and the image processing unit is connected to the display screen. The received transition zone signal of the adjacent channel is superimposed with the transition zone signal of this channel to realize the edge fusion of the image. The present invention can effectively eliminate the inter-slit aberration visually by generating image transition bands on the circuit hardware to make them merge, and realize the inter-slit aberration-free display of moving images.

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...
