Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figure 1 to Figure 5 Shown, a kind of LVDS video signal of the present invention is converted into 8LANE parity split-screen MIPI video signal method, comprises the following steps:

[0041] The LVDS video signal includes four links LINK1, LINK2, LINK3 and LINK4. The four links transmit the LVDS video signal sequentially according to the order of video pixels. The LVDS video signal of each link includes the LVDS receiving clock and LVDS data. The LVDS data is transmitted by the LVDS Data bus transmission, LVDS data bus includes several signal lines, each signal line transmits serial coded signal; MIPI video signal includes left channel MIPI video signal and right channel MIPI video signal, used for MIPI display of 8LANE odd-even split screen type mod.

[0042] LVDS video signal refers to the general term for signals cha...

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...
