Abstract: The present disclosure relates to a data driving circuit and a display device including the same, and the data driving circuit includes a plurality of data input terminals to which pixel data of an input image is input, and a plurality of voltage input terminals to which gamma tab voltages for each color having different voltage levels, and common gamma tab voltages having different voltage levels are each input. When the input image includes pixel data having different grayscale values for each color, a data voltage of a corresponding color is changed when any one of the gamma tab voltages for each color is changed, and data voltages of all colors are changed when any one of the common gamma tab voltages is changed.

Abstract: The present disclosure relates to a display panel and a display device using the same, and includes a first pixel area in which pixels connected to a first cathode electrode are disposed, and a second pixel area in which pixels connected to a second cathode electrode are disposed. A data voltage of pixel data to be written to a pixel in the second pixel area is applied to a first gate electrode of a driving element disposed in the second pixel area. A compensation voltage for increasing the luminance of the second pixel area is applied to the gate electrode of the driving element.
