Abstract
A representative system for displaying images comprises a pixel array, a conversion circuit, a memory device, and a compensation circuit. The pixel array has a plurality of pixels, each having at least one organic light emitting element equipped with a sensing unit which retrieves display information when the organic light emitting element retrieves a test signal. The conversion circuit determines a display parameter of each organic light emitting element according to the test signal and the display information of each organic light emitting element. The memory device stores the display parameter of each organic light emitting element. The compensation circuit modifies a video signal in accordance with the display parameters stored in the memory device.
