Method and system for converting LVDS video signal into DP1.2 video signal

Abstract

The invention relates to a method and system for converting an LVDS video signal into a DP1.2 video signal, and the method comprises the steps: enabling the LVDS video signal to be converted into an RGB video signal; carrying out the buffering and frequency multiplication of the RGB video signal, and the outputting a frequency multiplication signal; carrying out the configuration and transformation of DP1.2 conversion of the outputted frequency multiplication signal according to a DP1.2 conversion configuration command and a DP1.2 conversion starting command, and obtaining a DP1.2 video signal. The method carries out the detection of the maximum DP1.2 video resolution, is high in integration degree, is reliable in operation, is strong in capability of interference resistance, is simple in operation, is economical and practical, can improve the detection reliability and efficiency of a DP1.2 liquid crystal module group, reduces the equipment cost and production cost, and will further facilitate the popularization of related display equipment.

Description

technical field [0001] The invention relates to the generation of DP1.2 video signals, specifically a method and system for converting LVDS video signals into DP1.2 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. ...

AI Technical Summary

Problems solved by technology

[0004] However, the test device of DP1.2 liquid crystal module needs to output the same DP1.2 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, and its test device also It will continue to be used if it has not entered the replacement cycle

Although module manufacturers also produce DP1.2 LCD modules, in order to protect investment and reduce production costs, it is impossible to eliminate existing equipment and re-purchase expensive DP1.2 module-specific test equipment in large quantities
