Abstract:
1. A display device comprising: a data driver configured to transmit a plurality of data signals; a scan driver configured to generate and transmit a plurality of scan signals; 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 a first power source voltage and a second power source voltage; a display unit comprising the plurality of pixels coupled to corresponding ones of a plurality of data lines configured to transmit the plurality of data signals, to corresponding ones of a plurality of scan lines configured to transmit the plurality of scan signals, to a first control line configured to transmit the first control signal, to a second control line configured to transmit the second control signal, to a first voltage line configured to transmit the first power source voltage, and to a second voltage line configured to transmit the second power source voltage; and a timing controller configured to generate the plurality of data signals by processing external image signals and generate a plurality of driving control signals for controlling driving of each of the data driver, the scan driver, the compensation control signal unit, and the power controller.
