Abstract: A display device includes: a memory; a pixel unit including first pixels disposed with a first density in a first area and second pixels disposed with a second density smaller than the first density in a second area in contact with the first area; and a degradation compensator which updates degradation information stored in the memory, based on input grayscales for the first and second pixels, and changes the input grayscales to output grayscales, based on the degradation information. The degradation compensator stores the degradation information in the memory in a unit of block for the pixel unit. The memory stores only first degradation information for each of first blocks including only the first pixels, stores only second degradation information for each of second blocks including only the second pixels, and stores the first and second degradation information for each of third blocks including both the first and second pixels.

Abstract: A liquid crystal display and a method for driving the same. The liquid crystal display includes: gate lines arranged in a row direction; data lines arranged in a column direction; and subpixels arranged in basic units of eight subpixels. Each subpixel is each connected to one of the gate lines and one of the data lines, and the subpixels are continuously arranged along a row and are arranged in a matrix. In the basic units, polarities between adjacent subpixels from a first subpixel to a fourth subpixel along the row are opposite to each other, polarities between adjacent subpixels from a fifth subpixel to an eighth subpixel along the row are opposite to each other, and polarities of the fourth subpixel and the fifth subpixel are the same.

Abstract: A display device may include a first transistor, a light emitting device, a sensor capacitor, and an insulating layer. The light emitting device may be electrically connected to the first transistor and may include a pixel electrode, a common electrode, and a light-emitting member positioned between the pixel electrode and the common electrode. The sensor capacitor may include a first capacitor electrode, a second capacitor electrode, and a dielectric layer. The dielectric layer may be positioned between the first capacitor electrode and the second capacitor electrode, may directly contact both the first capacitor electrode and the second capacitor electrode, and may not emit light. The second capacitor electrode may be electrically connected to the common electrode. A face of the insulating layer may directly contact each of the pixel electrode and the first capacitor electrode.
