Claim 6:
7. A liquid crystal controller, used for:
acquiring driving configuration information of the liquid crystal module, the driving configuration information is used for indicating the number of configured LCD drivers;
receiving a color image frame and decomposing the color image frame into three monochrome frame images;
performing segmentation processing on each monochrome frame image according to the driving configuration information to obtain monochrome frame segmentation image data corresponding to each display area of the liquid crystal module;
when the liquid crystal controller starts to output each monochrome frame, a monochrome frame color indication signal is simultaneously output to a backlight module to indicate a current output color frame; packaging the monochrome frame segmentation image data corresponding to each display area, and sending data to the LCD driver corresponding to each display area, so that after the LCD driver receives each monochrome frame segmentation image data; according to display control information of the corresponding display area and the received monochrome frame segmentation image data, the LCD driver writes the received monochrome frame segmentation image data into the liquid crystal module to drive the display area corresponding to the liquid crystal module to display, and meanwhile after writing a line, outputting a synchronization signal to instruct the corresponding backlight module to start synchronously controlling a backlight delay circuit action; and

packaging data; in each line of signal of the monochrome frame segmentation image data of the corresponding LCD driver, 3 consecutive pixel points are taken as one RGB protocol point in a standard color protocol; if the number of pixel points of a current line in the display area is not a multiple of 3, then it is filled with “0”, until it is enough to form a full protocol point.
