Abstract:
1. A display device comprising: a data driver transmitting a plurality of data signals and a predetermined bias voltage; a scan driver generating and transmitting a plurality of scan signals; a display panel including a plurality of pixels, each emitting light with a driving current according to the plurality of data signals; a compensation signal unit generating and transmitting a compensation control signal for controlling simultaneous transmission of the predetermined bias voltage to each of the plurality of pixels before a data voltage according to the plurality of data signals is applied to each of the plurality of pixels; a power controller controlling voltage levels of a first power source voltage and a second power source voltage and supplying the level-controlled first and second power source voltages; and a timing controller generating the plurality of data signals by processing an external image signal and generating a plurality of driving control signals that respectively control driving of the data driver, the scan driver, the compensation signal unit, and the power controller, each of the plurality of pixels including a first capacitor and a second capacitor, wherein the first capacitor stores the predetermined bias voltage and the second capacitor stores the data voltage.
