Abstract:
A control method is for inputting a plurality of image frame data into a liquid crystal display device in order. The liquid crystal display device includes a plurality of light-emitting units as the backlighting and a display screen, and has a preset display mode reference. The display screen is divided into a plurality of display areas, and each image frame data has a plurality of area image frame data corresponding to each display area. The method includes an area image frame data comparison/judgment procedure and an area light-emitting unit control procedure. The area image frame data comparison/judgment procedure, which is applied to one display area, is to compare at least two area image frame data displayed in the display area at different timings so as to generate an area image display parameter, and then to determine whether the display area should perform an area synchronization flash control mode or not according to the area image display parameter and the display mode reference. If the area image frame data comparison/judgment procedure determines that the display area should perform the area synchronization flash control mode, the area light-emitting unit control procedure is to control the light-emitting unit corresponding to the display area to perform the area synchronization flash control mode.
