Abstract
A display device includes a display panel, a driver IC, and a control circuit. The control circuit includes operation circuitry to calculate the magnitude of a driving current flowing in a first pixel column in response to first voltage information from the driver IC, where the first voltage information corresponding to a voltage level of a first power supply line applied to a first pixel group of the display panel. The operation circuitry also calculates a compensation gain by comparing the magnitude of the driving current with preset current information. Further, the control circuit includes a compensator to receive a first data signal, generate a second data signal by applying the compensation gain to the first data signal, and transfer the second data signal to the driver IC. The display device and driving method may suppress image quality degradation by monitoring a high-potential voltage and correcting a data signal.
