Abstract:
1. A display device, comprising: a scan driver configured to apply scan signals and emission control signals through a plurality of scan lines and a plurality of emission control lines; a data driver configured to apply data signals through a plurality of data lines; a power supply unit configured to supply power through a plurality of power supply inlet portions; a pixel unit including a plurality of pixels that receives the scan signals, the emission control signals, the data signals and the power so as to display an image, the pixel unit being partitioned into a plurality of partition areas to correspond to the respective power supply inlet portions; and a current limit circuit configured to calculate values of current for each of the partition areas based on gray scale data of an image signal, and configured to correct the gray scale data so as to limit luminance of the pixel unit when at least one of the values of current for each partition area is a reference value or more, wherein the current limit circuit includes:
