Abstract: A display apparatus includes a display panel including a plurality of pixels, a gate driver which applies a bias gate signal to the pixels, a data driver which applies a data voltage to the pixels, an emission driver which applies an emission signal to the pixels, and a driving controller which controls the gate driver, the data driver, and the emission driver. The driving controller calculates a grayscale change region of input image data and a grayscale change level of the grayscale change region, determines a compensation region of the input image data based on the grayscale change region, determines a compensation grayscale voltage based on the grayscale change level, and compensates for the compensation region of the input image data based on the compensation grayscale voltage to generate output image data.

Abstract: A display device includes a substrate having a first region in which an image is displayed, a second region in which an image is not displayed, and a bending region connecting the first region and the second region. The bending region is configured to bend along a bending axis which extends in a first direction. A plurality of pad terminals is disposed within the second region. A first width of the bending region, measured along the first direction, is narrower than a second width of the second region, measured along the first direction.

Abstract: A display device includes: a display panel having a first region and a second region defined in the display panel, in which the second region is adjacent to the first region in a first direction. The display panel includes: a first pixel disposed in the first region, a second pixel disposed in the second region, a first bias voltage line electrically connected to the first pixel to transmit a first bias voltage, and a second bias voltage line electrically connected to the second pixel to transmit a second bias voltage. A time point, at which a level of the first bias voltage is changed, differs from a time point at which a level of the second bias voltage is changed, when the display panel operates at a first frame frequency.

Abstract: A display includes a plurality of pixels in a non-quadrangular display area and a plurality of first driving circuits and a plurality of second driving circuits in a peripheral area of the display area. Each of the pixels is connected to a first signal line in a first direction and a second signal line in a second direction crossing the first direction. Each of the first driving circuits outputs a first signal to the first signal line of a corresponding one of the pixels. Each of the second driving circuits outputs a second signal to the second signal line of a corresponding one of the pixels. The number of second driving circuits between neighboring first driving circuits is different depending on a position in the peripheral area.
