OLED DISPLAY DEVICE COMPENSATING IMAGE DECAY

摘要

An OLED display device includes a display screen, a sensor, and a timing controller. The timing controller includes a detection unit, a test image generation unit, a data compensation unit, and image control unit. The detection unit provides a command for generating a test image. The test image generation unit generates a test image according to the command. The data compensation unit receives a decayed signal that corresponds to the test image and is detected by the sensor in order to generate a compensation signal according to the decayed signal. In response to the compensation signal, the image control unit compensates an external image to achieve normal displaying of the external image on the display screen.
