Abstract
A display device includes a data driver; a scan driver; a compensation control signal unit configured to reset voltages of data signals transmitted to a plurality of pixels during a previous frame at a current frame, and configured to generate and transmit a first control signal to compensate for threshold voltages of driving transistors of the pixels and a second control signal to control simultaneous light emission of the pixels; a power controller configured to control and supply the voltage levels of a first and second power source voltages; a display unit including the plurality of pixels coupled to corresponding data lines, scan lines, first control lines, second control lines, first voltage lines, and second voltage lines; and a timing controller configured to generate a plurality of data signals by processing external image signals and generate a plurality of driving control signals for controlling driving of the drivers.
