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. |

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 detection unit, an external image receiving unit, a test image generation unit, a selection unit, a data compensation unit, and an image control unit, the selection unit being connected to the detection unit, the external image receiving unit, and the test image generation unit and being also connected to image control unit; wherein the detection unit is configured to provide a command for generating a test image; the external image receiving unit is configured to receive an external image; the test image generation unit is configured to generate a test image according to the command; the selection unit is configured to select an input of the test image from the test image generation unit when receiving the command or to select an input of the external image from the external image receiving unit when not receiving the command, and then to feed the input to the image control unit; the image control unit 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 compensation unit 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 control unit to the display screen, and to generate a compensation signal that is transmitted to the image control unit; and wherein when the image control unit 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. |
