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.

Gate driving circuit and display device

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.

A parallax barrier type stereoscopic image display device comprises: an image panel that display a left-eye image and a right-eye image; a barrier panel that has a switchable barrier comprising a liquid crystal layer, a reference electrode positioned above the liquid crystal layer, and a plurality of driving electrode channels positioned below the liquid crystal layer, each of which is controlled independently, and selectively blocks light from the image panel; and a driver that supplies a reference voltage to the reference electrode and applies a channel driving voltage to the driving electrode channels to form a barrier area and an open area in the switchable barrier.

Parallax barrier type stereoscopic image display device

Disclosed is a liquid crystal display apparatus which improves uniformity in luminance of RGB pixels by asymmetrically designing RGB pixels, and to enhances display quality, the apparatus comprises a red pixel switching element that switches a driving signal of the red pixel; a green pixel for transmitting green-colored light; a green pixel switching element that switches a driving signal of the green pixel; a blue pixel for transmitting blue-colored light; and a blue pixel switching element that switches a driving signal of the blue pixel, wherein a switching element of at least one pixel having relatively low luminance among the red pixel, green pixel and blue pixel is formed in the pixel area having relatively high luminance.
