Abstract: A display device and driving method thereof are disclosed. The display device includes a pixel emitting light at a luminance corresponding to an output grayscale value and a color shifter for converting an input grayscale value into the output grayscale value based on output color gamut information. The color shifter includes an offset storage unit storing reference color gamut information and offset information; and a color gamut determination unit that determines the output color gamut information using the reference color gamut information and the offset information when the color shift level corresponds to a value between the reference level and the shift levels, and determines tire output color gamut information using second offset information in which the offset information is inverted and the reference color gamut information when the color shift level is not between the reference level and the shift levels.

Abstract: A display apparatus includes a display panel, a contrast analyzer, a contrast processor and a data driver. The display panel includes a plurality of sub display areas. The display panel is configured to display an image based on input image data. The contrast analyzer is configured to analyze the input image data in a time division method. The contrast processor is configured to adjust contrast of the input image data based on analysis result of the contrast analyzer. The data driver is configured to generate data voltages based on output data of the contrast processor. A number of contrast analysis cores of the contrast analyzer is determined according to a number of the sub display areas and a frame rate.

Abstract: An electronic device comprises a first display panel including first pixels which display a left eye image, a second display panel including second pixels which display a right eye image, and a display panel driver configured to apply a left eye data voltage to the first pixels and to apply a right eye data voltage to the second pixels. The first display panel and the second display panel are configured to operate in a 2D image mode in which the left eye image and the right eye image which are identical to each other are displayed or to operate in a 3D image mode in which the left eye image and the right eye image which are different from each other are displayed, based on an image motion value and a 3D depth value.

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.

Abstract: A display device includes a display panel, a data driver and a demultiplexer circuit. The display panel includes first, second, third and fourth data lines, and first, second, third and fourth sub-pixels respectively coupled to the first, second, third and fourth data lines. The data driver includes a first output channel and a second output channel. The demultiplexer circuit selectively couples at least one of the first data line and the third data line to the first output channel in response to first and second switching signals, and selectively couples at least one of the second data line and the fourth data line to the second output channel in response to third and fourth switching signals different from the first and second switching signals.
