Title:
LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY PANEL DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/113688
Kind Code:
A1
Abstract:
A liquid crystal display panel driving method, comprising: dividing pixels on a display component into a plurality of pixel groups (S110), each pixel group comprising an even number of pixels in a matrix arrangement; obtaining an average greyscale value of a simple random sampling number of blue sub-pixels within each sub-pixel group according to a picture input signal (S120); obtaining two target greyscale value pairs according to the average greyscale value of each pixel group (S130), each target greyscale value pair comprising one high and one low greyscale value, a front viewing angle brightness of the one high and one low greyscale value being the same as a front viewing angle brightness of the average greyscale value; obtaining two corresponding driving voltage pairs according to the two target greyscale value pairs within each pixel group (S140); driving the blue sub-pixels on the corresponding pixel group according to the two driving voltage pairs (S150). The liquid crystal display panel driving method effectively improves the defect that large viewing angle blue sub-pixel premature saturation causes colour deviation. The present invention also relates to a liquid crystal display device.
