Method and device for achieving data signals of various LANE numbers of MIPI (mobile industry processor interface) based on FPGA (field programmable gate array)

Abstract

The invention discloses a method and a device for achieving data signals of various LANE numbers of an MIPI (mobile industry processor interface) based on an FPGA (field programmable gate array). The method includes 1), receiving MIPI configuration information from an upper layer to perform configuration operation, wherein the MIPI configuration information includes the LANE numbers of an MIPI module, a module screen-splitting mode, RGB (red-green-blue) bit width, MIPI transmission control parameters and MIPI output electrical configuration; 2), converting input RGB video signals into four-channel screen-splitting video data; 3), converting the four-channel screen-splitting video data into four-channel byte data; 4), packing the four-channel byte data to form four-channel MIPI packed data; 5), allocating the four-channel MIPI packed data to each data LANE to form MIPI signals; 6), subjecting the MIPI signals of each data LANE to MIPI transmission operation; 7), subjecting the MIPI signals of each data LANE to output electrical and transmission characteristic adjustment, and then sending the MIPI signals of each data LANE to the module. The method and the device have the advantages that output of the MIPI signals of 1-LANE, 2-LANE, 3-LANE, 4-LANE, 8-LANE and 16-LANE is achieved through the FPGA to lighten the module, and the method and the device are simple to operate, high in reliability and quite low in cost.

Description

technical field [0001] The invention relates to the field of display and testing of MIPI liquid crystal modules, in particular to a method and device for realizing data signals of various MIPI LANE numbers based on FPGA. Background technique [0002] MIPI display module (hereinafter referred to as module) is a display device widely used in various portable display devices and mobile phones. This type of module and the MIPI video signal it uses have low power consumption, high reliability, and High rate, can adapt to the characteristics of different sizes and resolutions. [0003] When displaying video images with small and medium resolutions, the video signals will be distributed to the MIPI data lines of 1 to 4 LANEs and sent to the module. The higher the video resolution, the greater the amount of data, and the video signals will be distributed to the MIPI data The number of LANE lines is also more. When displaying ultra-high-definition resolution video images, the amoun...
