Method for converting LVDS video signals into MIPI video signals

Abstract

The invention discloses a method for converting LVDS video signals into MIPI video signals. The method comprises the following steps of 1 respectively and simultaneously receiving and demodulating each link of the LVDS video signals to produce parallel demodulation data and LVDS pixel clocks of all of links; 2 performing video decoding to the parallel demodulation data of all of links to generate LVDS video source signals of all of links, wherein the LVDS video source signals include LVDS video source data and LVDS video source synchronizing signals, and the LVDS pixel clocks are converted into LVDS video source pixel clocks; 3 converting the LVDS video source signals of all of links into RGB video signals; 4 converting the RGB video signals into the MIPI video signals. The method has the advantages of being simple in operation, high in detecting efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of display and testing of liquid crystal modules, in particular to a method for converting LVDS video signals into MIPI video signals. 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 dedicated liquid crystal module testing device and input them to the liquid crystal module for display. Strict and comprehensive testing of its display effect. The display interface and internal display proce...

Problems solved by technology

[0004] However, the testing device of MIPI LCD module needs to output the same MIPI test signal, but the existing common LCD module testing device does not have this function, and the common LCD module continues to be produced, and its testing device has not yet entered the replacement cycle will continue to use

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