Method and system for converting LVDS video signals into V-BY-ONE video signals suitable for 32 Lane

Abstract

The invention relates to a method and system for converting LVDS video signals into V-BY-ONE video signals suitable for 32 Lane. The method comprises that an LVDS video signal transmitted in an 8-Link manner is received and demodulated to generate LVDS parallel demodulation data and an LVDS pixel clock; according to an LVDS video decoding control signal, video decoding is carried out on the LVDS parallel demodulation data to generate LVDS video source data and LVDS video source synchronization signal; according to an LVDS video converting control signal, the LVDS video source data and LVDS video source synchronization signal are converted into RGB video signals; and after a V-BY-ONE video conversion starting command is received, the RGB video signals are converted into 32Lane V-BY-ONE video signals. According to the method and system, the quality of LVDS video signals and the accuracy of image data can be detected, and the method and system are characterized by high reliability, misjudgment free, simple operation, high detection efficiency and low cost.

Description

technical field [0001] The invention relates to the generation of V-BY-ONE video signals, specifically a method and system for converting LVDS video signals into V-BY-ONE video signals, and belongs to the field of display and testing of liquid crystal modules. Background technique [0002] Liquid crystal display module (Liquid Crystal Display Module, hereinafter referred to as liquid crystal module) is a key component for liquid crystal display equipment to display normally. It is composed of liquid crystal screen, backlight original, display processing chip and circuit. The structure of the liquid crystal module is precise, the manufacturing process is complicated, and the production process requires high requirements. In order to ensure the yield rate during production, it is necessary to generate various test video signals through a special liquid crystal module test device and input them to the liquid crystal module for display, so as to perform strict and comprehensive t...

Problems solved by technology

[0004] However, the test device of V-BY-ONE liquid crystal module needs to output the same V-BY-ONE test signal, but the existing common liquid crystal module test device does not have this function, and the common liquid crystal module is still in production, Its test equipment has not yet entered the replacement cycle and will continue to be used

Although module manufacturers also produce V-BY-ONE LCD modules, in order to protect investment and reduce production costs, it is impossible to eliminate existing equipment and re-purchase expensive special test devices for V-BY-ONE modules in large quantities.
