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: 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.

Abstract: A display device includes a display panel, a control circuit, and a data driving circuit. The display panel displays an image based on data voltages, and includes a display area divided into a plurality of blocks. The control circuit receives input image data, determines a boot-up area among the blocks when the input image data is a moving image, and generates output image data by increasing low-grayscale values lower than a threshold grayscale among input grayscale values of the input image data in the boot-up area. The data driving circuit generates the data voltages based on the output image data.

Abstract: A display apparatus includes: a display panel including a plurality of pixels; a data driver which applies data voltages to the pixels; a gate driver which applies gate signals to the pixels; and a driving controller which controls the data driver and the gate driver. The driving controller divides the display panel into a plurality of panel blocks, calculates a skin color inclusion ratio of each of the panel blocks based on input image data, determines at least one face region candidate block among the panel blocks based on the skin color inclusion ratio, determines a face region block of the at least one face region candidate block based on the at least one face region candidate block and face matching data, and performs image quality processing on the face region block.
