Abstract: Provided is a color compensation device of an electronic device including a first color converter, a parameter generator, an operator, and a second color converter. The first color converter receives an image signal, converts the image signal into initial tristimulus values based on a basic look-up table, and generates a conversion look-up table using the basic look-up table. The parameter generator extracts 2N number of representative parameters from the conversion look-up table and generates N number of compensation parameters on the basis of the 2N number of representative parameters. N is a natural number. The operator generates compensated tristimulus values at each gray scale using the N number of compensation parameters, generates a compensation look-up table, and converts the initial tristimulus values into the compensated tristimulus values using the compensation look-up table. The second color converter converts the compensated tristimulus values into a compensated image signal.

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.
