AI Technical Summary
Existing organic light-emitting display panels suffer from uneven display, which affects the display effect.
N first zones and M second zones are arranged alternately in the display area of the display panel. By using differentiated compensation data voltage, scanning signals are output to these zones at different time periods for initialization. The brightness compensation zone is determined according to the reset frequency or pulse number of the light-emitting device, and the compensated data voltage is output to the brightness compensation zone to reduce the difference between the actual display brightness and the theoretical brightness.
It improves the problem of uneven brightness caused by differences in anode initialization load, solves the problem of screen splitting on the display panel, and improves the display effect.
