Display driving module with multi-path display output, mainboard, and method multi-path display output

Abstract

It is a kind of display drive module and method that with multiple display output. It can solve the problem that single display drive module cannot drive multiple displays. The display drive module can process and convert multiple image signals that in image memory to multiple digital video signals and output them by image processing controller. The output of image processing controller connects to multiple analog-digital converter, which can convert the digital video signal to analog R, G, B signal and output them. The output of each analog-digital converter connects to display, and enables the displays to display the image data according to the received signal. So this single display drive module drives multiple displays and updates image of them simultaneously.

Description

technical field

[0001] The invention relates to a display drive module with multiple display outputs, a main board and a method for multiple display outputs, in particular to a drive module for driving a display. Background technique

[0002] Currently used operating systems such as Windows 98 / ME / 20000 / XP all support the multi-screen display function, and multiple monitors can be connected through the host computer to display different image frames. The places where this technology is generally used, such as the train schedule displayed at the train station or airport, or the video wall displayed real-time information in the financial securities industry.

[0003] figure 1 The drawing is a schematic diagram of a host computer connected with multiple monitors. Generally, on the motherboard of the computer mainframe 1, several slots for expanding functions (such as slots supporting PCI or ISA specifications) are provided. In addition to related support, several slots must b...
