SYSTEM AND METHOD FOR REDUCING MURA DEFFECT

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for reducing mura defects in an organic light emitting diode display.

SOLUTION: The system for reducing mura defects comprises: a pixel array having a plurality of pixels, each having an organic light emitting element equipped with a sensing unit which retrieves display information corresponding to the organic light emitting element retrieving a test signal; a conversion circuit that determines a display parameter of each organic light emitting element according to the test signal and the display information; a memory device that stores the display parameters of each organic light emitting element; and a compensation circuit that modifies a video signal in accordance with the display parameters stored in the memory device and drives the pixel array.
