Abstract: An electroluminescent display device includes a display panel in which a plurality of pixels are disposed, each pixel including a first sub pixel, a second sub pixel, a third sub pixel, and a fourth sub pixel each having a different color; a data driver which supplies a data voltage to the plurality of pixels by means of a plurality of data lines; and a gate driver which supplies a gate signal to the plurality of pixels by means of a plurality of gate lines. Each of the plurality of data lines is divided into a plurality of sub data lines, and each of the plurality of sub data lines is connected to a plurality of sub pixels having the same color, the sub pixel includes a switching transistor, and a source electrode of the switching transistor includes a compensation pattern which is provided on at least one side of the source electrode spaced apart from the gate line, thereby improving luminance difference between sub pixels having the same color which are converted by the exposure overlay shift of the gate line.

Abstract: A display device can include a display panel including a plurality of pixels configured to be driven in one of a driving period and a blank period, a timing controller configured to output a variable refresh rate (VRR) signal determining a refresh rate of the plurality of pixels and a video data signal, and a data driver configured to supply a data voltage to the plurality of pixels through a plurality of data lines, according to the VRR signal and the video data signal. The plurality of pixels can be driven at a first refresh rate or a second refresh rate which is lower than the first refresh rate, according to the VRR signal. Further, when the plurality of pixels are driven at the second refresh rate and the video data signal is a low grayscale video data signal, the output luminance of each of the plurality of pixels can be reduced during the blank period.
