Abstract

The present invention involves a display driver, which includes at least the processing module, and the processing module is connected to the analog signal interface, digital signal interface, and display interface interface. Among themInformation; Digital signal interface is used to enter the digital signal information corresponding to the resolution, color, and refresh rate of the screen; the processing module is used to process the analog signal information and digital signal information to obtain the display of the display screen;It is used to display according to the display of the display signal drive signal. In this way, different types of display signal access can be achieved, and the general design of the board card can be achieved.The reliability and maintenance of the system.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a display driving board. Background technique [0002] In the prior art, CN112004044A, CN201307396Y, CN210223511U, and CN201017612Y patent documents disclose the driver board of the display screen. The interface of the driver board of the display screen is single. If a digital signal is input, the corresponding digital driver board needs to be matched. Signals need to be input to the analog driver board, which needs to be switched back and forth during use. If digital signals and analog signals need to be connected at the same time, they cannot be compatible and it is not convenient to use. Contents of the invention [0003] The present invention intends to provide a display driving board to solve the deficiencies in the prior art, and the technical problem to be solved by the present invention is achieved through the following technical solutions. [0004] In a first ...
