Abstract

The present invention relates to a method of transforming an LVDS video signal into a DP video signal. The method comprises the steps of receiving and demodulating the LVDS video signal to generate the LVDS parallel demodulation data and an LVDS pixel clock; carrying out the video decoding on the LVDS parallel demodulation data according to an LVDS video decoding control signal to generate the LVDS video source data and an LVDS video source synchronizing signal; transforming the LVDS video source data and the LVDS video source synchronizing signal into an RGB video signal according to an LVDS video transformation control signal, and carrying out the corresponding frequency multiplication operation on the LVDS pixel clock to generate a corresponding RGB video pixel clock; transforming the RGB video signal into the DP video signal after receiving a DP video transformation starting command. The method and the system of the present invention can detect the LVDS video signal quality and the image data accuracy, and have the characteristics of being high in reliability and detection efficiency and low in cost, not having misjudgement and being simple to operate.

Description

technical field [0001] The invention relates to the generation of DP video signals, in particular to a method and system for converting LVDS video signals into DP video signals, and belongs to the field of display and testing of liquid crystal modules. Background technique [0002] Liquid crystal display module (LiquidCrystalDisplayModule, 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 testing. it...
