Abstract

Provided are a gate driver and a display device. A low-resolution area is disposed in a portion of a display 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 an 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.

Description

technical field [0001] Embodiments relate to gate drivers and display devices. Background technique [0002] With the development of the information society, demands on display devices for displaying images are increasing. In this regard, a range of display devices such as liquid crystal display (LCD) devices and organic light emitting diode (OLED) display devices have recently been widely used. [0003] Such a display device may include a display panel in which a plurality of gate lines, a plurality of data lines, and a plurality of sub-pixels are disposed, and various driving circuits for driving the gate lines, data lines, and the like. In addition, the display panel may include a display area in which a plurality of sub-pixels are disposed to display an image, and a non-display area outside the display area in which signal lines and the like are disposed. [0004] Here, depending on the type of the display device, the display device may include a camera sensor, a proxi...
