Method and device for compensating brightness of AMOLED display panel

摘要

A method and a device for compensating brightness of an AMOLED display panel are provided. The method is simple, and the device is simple in structure and is easy to operate. By performing an aging experiment on the display panel in advance, an attenuation law that the brightness of sub-pixels varies with time and gray levels is obtained, and a compensation data is computed and a dynamic compensation table is generated. A correcting module corrects the inputted original gray levels based on the dynamic compensation table and the brightness of sub-pixels are compensated such that the display panel can display images normally.
