Abstract

The invention provides a signal transmission device and a related method. The signal transmission device comprises a first master signal conversion circuit and at least one first slave signal conversion circuit. The first main signal conversion circuit is used for receiving first partial data of output data from a data generation unit, converting the first partial data into a corresponding first transmission signal and outputting a first synchronization signal. The at least one first slave signal conversion circuit is used for receiving at least one second partial data corresponding to the output data from the data generation unit and converting the at least one second partial data into at least one corresponding second transmission signal. Wherein the at least one first slave signal conversion circuit controls the timing of the at least one second transmission signal according to the first synchronization signal.

Description

technical field [0001] The present invention relates to a display system, in particular to a signal transmission device and a related signal transmission method used in the display system. Background technique [0002] In a display system, timing alignment between circuits is generally implemented through a horizontal synchronization signal (Horizontal Sync, H-sync) and a vertical synchronization signal (Vertical Sync, V-sync). Usually, the image generator will send out the H-sync signal when the pixel data of one line (row) in the image is transmitted, and send out the V-sync signal when the pixel data of a whole (frame) image is transmitted, and the display panel The driver can control the driving timing of the display panel according to these synchronous signals. In a display system with high resolution and high color depth, in order to meet the transmission speed, the pixel data of an image will be transmitted from the image generator to the display panel driver through...
