Claim Text:
1. An organic light emitting diode (OLED) display device, which comprises: a display screen, a sensor, and a timing controller, wherein the display screen is configured to display an image and the sensor is configured to detect a decayed signal of the display screen when displaying; wherein the timing controller comprises a detector, an external image receiver, a test image generator, a selector, a data compensator, and an image controller, the selector being connected to the detector, the external image receiver, and the test image generator and being also connected to the image controller; wherein the detector is configured to provide a command for generating a test image; the external image receiver is configured to receive an external image; the test image generator is configured to generate a test image according to the command; the selector is configured to select an input of the test image from the test image generator when receiving the command or to select an input of the external image from the external image receiver when not receiving the command, and then to feed the input to the image controller; the image controller is configured to transmit the test image to the display screen for detecting decay of a display screen in response to the input of the test image; and the data compensator is connected to the sensor and is configured to receive a decayed signal of the display screen detected by the sensor, the decayed signal corresponding to the test image transmitted from the image controller to the display screen, and to generate a compensation signal that is transmitted to the image controller; and wherein when the image controller transmits the external image to the display screen, the external image is compensated according to the compensation signal so that the external image is displayed normally on the display screen.
