Abstract: A display apparatus includes a display panel, an afterimage compensator and a data driver. The display panel displays an image. The afterimage compensator writes first stress data of input image data corresponding to a first area to a first memory area in a first block size and second stress data of the input image data corresponding to a second area to a second memory area in a second block size different from the first block size and compensates a grayscale value of the input image data based on the first stress data and the second stress data. The data driver generates a data voltage based on a compensated grayscale value and outputs the data voltage to the display panel.

Abstract: A display device includes a display panel which displays an image, and a panel driving block which receives a control signal and generating a criterion point signal including information about a criterion point for adjusting luminance of the image based on the control signal. The panel driving block receives image signals, generates a correction value based on distance information about a location of the display panel, at which each of the image signals is displayed, and the criterion point, and generates correction image signals by converting the image signals based on the correction value.

Abstract: Provided is an input detection unit with a plurality of first electrodes and second electrodes insulated from the first electrodes. Dummy patterns are disposed between the patterns and the detection patterns. A secondary dummy pattern is disposed adjacent to the dummy patterns. Signal lines overlap the non-detection area. The signal lines include a first signal line connected to the patterns and a second signal line connected to the detection patterns. The plurality of patterns includes a row of patterns closest to the non-detection area. The secondary dummy pattern overlaps a portion between the row of patterns closest to the non-detection area and the second signal line.

Abstract: An electronic apparatus has a through module hole defined in an active area and includes a first sensing pattern and a second sensing pattern spaced apart from each other in one direction with the module hole disposed therebetween. A third sensing pattern and a fourth sensing pattern are spaced apart from each other in a direction crossing the one direction with the module hole disposed therebetween. A first connection line extends along a portion of the module hole and connects the first sensing pattern and the second sensing pattern to each other. A second connection line extends along a portion of the module hole and connects the third sensing pattern and the fourth sensing pattern to each other. The first connection line and the second connection line are disposed on the same layer and are spaced apart from each other.

Abstract: An electronic device includes a main processor that provides an image signal and an image-sticking correction signal, and a display module that receives the image signal and the image-sticking correction signal and outputs an image data signal obtained by compensating for the image signal. The display module includes a compensation circuit that calculates cumulative stress based on the image data signal and outputs an image-sticking compensation signal and a compensation adjuster that outputs the image data signal obtained by correcting the image signal based on the image-sticking correction signal and the image-sticking compensation signal. The image-sticking correction signal is input by a user manipulation.
