Abstract: A display device includes a display panel including a first region and a second region, and a sensing module on a rear side of the display panel. The first region includes a first pixel area to display an image. The second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module. The second region overlaps the sensing module. The second pixel area overlaps a first layer that blocks light output by the sensing module. The transmission area does not overlap the first layer.

Abstract: A display has an array of pixels each of which has a light-emitting diode (30) such as an organic light-emitting diode. A drive transistor (TD) and an emission transistor (TE) are coupled in series with the light-emitting diode (30) of each pixel (22) between a positive power supply (VDDEL) and a ground power supply (VSSEL). The pixels (22) include first and second switching transistors (T1, T2). A data storage capacitor (Cst1) is coupled between a gate and source of the drive transistor (TD) in each pixel. Signal lines (Data) may be provided in columns of pixels to route signals such as data signals, sensed drive currents from the drive transistors, and predetermined voltages between display driver circuitry and the pixels. The switching transistors (T1, T2), emission transistors (TE), and drive transistors (TD) may include semiconducting-oxide transistors and silicon transistors and may be n-channel transistors or p-channel transistors.

Abstract: Disclosed is a display driving apparatus. The display driving apparatus includes a distance calculator configured to calculate, for a plurality of pixels constituting a frame input to a display panel, distances between respective pixels and a central pixel, a gain calculator configured to divide the frame constituted by the plurality of pixels into an interest area and a non-interest area using the distances between respective pixels and the central pixel, and to determine a gain of each pixel in accordance with an area where the pixel is disposed, and a gain applier configured to generate pixel data using the gain of each pixel. Gains of the pixels disposed in the interest area have a constant value. Gains of the pixels disposed in the non-interest area are decreased in proportion to distances between the pixels in the non-interest area and the central pixel, respectively.
