Abstract

The invention relates to the technical field of panel display, and discloses a display architecture, a display method and a display system, the display architecture is used for a display panel array,the display panel array comprises a plurality of display panels, and each display panel is connected to a display controller in parallel through a data transmission system. Each display panel is connected to a display controller in parallel through a data transmission system, and signal transmission of display content by using SPI among the display panels is avoided. According to the display device, the display panels are arranged in parallel, so that the EMI problem caused by SPI signal transmission among the display panels is eliminated, due to parallel transmission between the display controller and the display panels, the time delay among the display panels is greatly reduced, and the display synchronism among the display panels is enhanced.

Description

technical field

[0001] The present invention relates to the technical field of panel display, in particular to a display structure, a display method and a display system. Background technique

[0002] The current display panel industry usually adopts the splicing of multiple display panels to achieve high pixelation and high frame rate, and SPI is used to communicate and transmit images between panels, specifically as figure 1 As shown, the video box transmits images to all the display panels in the display panel array through one SPI, and the SPI serial connection method is used between the display panels to realize image transmission.

[0003] Among them, SPI is a digital signal with rich high-frequency harmonic components, so this communication method is more suitable for communication within the circuit board. If it is transmitted across the circuit board through cables, these high-frequency harmonic components will cause serious problems. Electromagnetic radiation (EMI...
