Abstract: A display device includes a pixel connected to a first gate line, an emission control line, a bias gate line, and a data line. A gate driver is configured to supply a first gate signal to the first gate line in an address scan period and configured to supply a bias write gate signal to the bias gate line in a self-scan period. An emission driver is configured to supply an emission control signal in the address scan period and in a self-scan period. A data driver is configured to supply a first data voltage to the data line in the address scan period and configured to supply a second data voltage to the data line in the self-scan period. The second data voltage is set based on the first data voltage.

Abstract: A display device includes a display panel including a first sub-pixel which displays a first color and is connected to a first data line and a gate line, a gate driver which provides a gate signal to the gate line, a source driver which provides a data voltage to the first data line in a display scan period of a frame and provides a first self-scan voltage to the first data line in a self-scan period of the frame, and a timing controller which calculates a first ratio of each of grayscale values of first color image data for the first color of the frame and determines the first self-scan voltage based on the first ratio.

Abstract: A display apparatus has an enlarged display area so that an image can be displayed in a sensor area. The display apparatus includes: a first base layer that includes a display area that includes a plurality of main pixels and a sensor area that includes a plurality of auxiliary pixels and a transmission portion; a conductive layer positioned on the first base layer and that corresponds to the plurality of auxiliary pixels; and a second base layer positioned on the first base layer with the conductive layer positioned between the second base layer and the first base layer. A resolution of an image displayed by the sensor area is lower than a resolution of an image displayed by the display area.
