Abstract: A data signal processing device includes a load calculator and a compensation processor. The load calculator calculates an on-pixel rate (OPR) based on image data signals and positional weight values. The positional weight values are determined based on locations of pixels in a display panel. The OPR is proportional to a frame luminance load, which corresponds to a sum of driving currents for the pixels to emit light in each of a plurality of frames. The compensation processor compensates distorted luminance caused by the frame luminance load based on the OPR.

Abstract: A display device may include a substrate, input pads, output pads, a driver, discharge patterns, and ground lines. The substrate may include a display area and a pad area. The input pads may be disposed in a first portion of the pad area. The output pads may be disposed in a second portion of the pad area. The driver may be disposed on the input pads and the output pads. The discharge patterns may be disposed adjacent to the driver in the pad area. The ground lines may electrically connect the discharge patterns and at least one of the input pads in the pad area.

Abstract: A display device includes: a similar gray level block detector configured to detect a pixel data block in which a gray level difference between a plurality of pixel data included in an image signal is smaller than or equal to a threshold; a skin tone detector configured to detect the pixel data block including a skin tone; and a gamma processor configured to apply a first gamma to a plurality of pixel data included in the pixel data block when the pixel data block does not include the skin tone and apply a second gamma to the plurality of pixel data included in the pixel data block when the pixel data block includes the skin tone.
