Abstract: A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.

Abstract: Provided is a timing controller configured to operate a display device. The timing controller includes a receiving unit receiving a still image signal; a transmitting unit outputting an output data used to display images; a clock frequency spreader generating a spread clock signal having a frequency value adjusted between first and second frequency values by modulating a reference clock signal; a memory system storing a first image data which corresponds to a first frame of an image, and outputting the first image data in response to the spread clock signal; and a still image managing unit communicating with the memory system in order to output the first image data as the output data. According to the timing controller, electro-magnetic interference may be reduced and operation errors of the display device may be prevented.
