Title: BRIGHTNESS COMPENSATION SYSTEM AND BRIGHTNESS COMPENSATION METHOD FOR OLED DISPLAY APPARATUS
Abstract:
A brightness compensation system and a brightness compensation method for an OLED display apparatus. The system comprises: an image pre-processing unit (10), an image contrast ratio control unit (50) electrically connected to the image pre-processing unit (10), an ageing compensation unit (20) electrically connected to the image contrast ratio control unit (50), an ageing parameter detection unit (30) electrically connected to both the ageing compensation unit (20) and the image contrast ratio control unit (50), and an OLED display panel electrically connected to both the ageing compensation unit (20) and the ageing parameter detection unit (30); before ageing compensation, the contrast ratio of an image to be displayed is improved by means of the image contrast ratio control unit (50) on the basis of ageing parameters, and ageing compensation of the image to be displayed having an improved contrast ratio and display of same is then performed. Reduction of the brightness of the OLED display apparatus due to ageing is thus prevented, ensuring the display quality of the OLED display apparatus and improving the user experience and the competitiveness of the product.
