Method for converting LVDS video signal into 8 LANE odd-even split screen MIPI video signals

Abstract

The invention discloses a method for converting an LVDS video signal into 8 LANE odd-even split screen MIPI video signals. The method comprises the steps of firstly, respectively and simultaneously conducting receiving and demodulation on each link of the LVDS video signal, and generating parallel demodulation data and LVDS pixel clocks of the four links; secondly, conducting video decoding on the parallel demodulation data of the four links, and generating LVDS video source data and LVDS video source synchronizing signals of the four links; thirdly, generating RGB video clocks, dividing the LVDS video source data of the four links into odd pixel parallel data and even pixel parallel data, simultaneously reading the odd pixel parallel data, the even pixel parallel data and the synchronizing signals by the RGB video clocks, and respectively converting the odd pixel parallel data and the even pixel parallel data into RGB odd split screen video signals and RGB even split screen video signals; fourthly, simultaneously converting the RGB odd split screen video signals and the RGB even split screen video signals into a left-channel MIPI video signal and a right-channel MIPI video signal.

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 an LVDS video signal into an 8LANE odd-even split-screen MIPI video signal. 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 inte...

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.
