Abstract: An organic light-emitting display device includes a substrate including an active area in which a plurality of pixels are defined, and a non-active area surrounding the active area and having a pad area in which a plurality of pads are disposed on one side of the active area; a plurality of power supply lines disposed in the active area; a plurality of test transistors disposed in the non-active area on another side of the active area; and a plurality of power supply transistors connected to the plurality of power supply lines. Each of the power supply transistors is disposed next to the respective test transistors. A uniform supply voltage can thus be applied across a plurality of pixels without any additional process such that uniformity of luminance can be improved.

Abstract: Provided are a gate driver and a display device. A low-resolution area is disposed in a portion of an active area, and an optical sensor is disposed on a side of the low-resolution area opposite to a surface of the low-resolution area on which an image is displayed, such that the display device displays images on the low-resolution area and performs sensing using the optical sensor. The low-resolution area and a high-resolution area surrounding the low-resolution area are driven using different gate lines. Image compensation for the low-resolution area is easily performed to reduce or remove the difference in the image quality between the low-resolution area and the surrounding areas.
