Title: METHOD AND DEVICE FOR COMPENSATING VIEWING ANGLE CHROMATIC ABERRATION OF DISPLAY DEVICE, AND DISPLAY DEVICE
Abstract:
A method and device for compensating viewing angle chromatic aberration of a display device, and the display device, the method for compensating viewing angle chromatic aberration of the display device comprising the following steps: receiving an inputted image, and looking up each pixel panel drive signal of the inputted image to respectively obtain corresponding first driving signals and second driving signals of each pixel in two adjacent frame images; calculating an average value of the first driving signals and an average value of the second driving signals respectively, and respectively calculating an average value of the first driving signal and the second driving signal within the same frame image; calculating a brightness compensation signal required by a backlight module of a backlight area according to the calculated average values and a given reference brightness signal; and performing viewing angle chromatic aberration compensation on a subsequent frame image according to the brightness compensation signal.
