Abstract: A method of driving a display device is provided. The display device includes a plurality of sensing unit groups arranged in a matrix form. Each of the plurality of sensing unit groups includes a plurality of sensing units and a sensing signal processing unit. The method includes applying scanning signals to a plurality of scanning signal lines respectively connected to the plurality of sensing units of a first sensing unit group among the plurality of sensing unit groups. Sensing signals are generated and outputed to at least one sensing signal line by a plurality of sensing units respectively receiving the scanning signals. The scanning signals are applied to two or more sensing units among the plurality of sensing units of the first sensing unit group in a first touch mode. The scanning signals are synchronized with each other.

Abstract: A controller includes a bit shifter and a stain compensator. The bit shifter may determine a bit shift value corresponding to a stain compensation value according to an area of a display panel. The bit shift value represents a quantity of integer bits and a quantity of decimal bits. At least one of the quantity of integer bits and the quantity of decimal bits corresponds to a quantity of stain compensation steps. The stain compensator may compensate a grayscale value of input image data using the stain compensation value and the bit shift value to generate compensated image data.
