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 apparatus includes a signal controller, a panel driver, and a display panel. The signal controller includes N functional blocks that process input image signals to output image data signals and convert input control signals to internal control signals to output the internal control signals. The panel driver converts the image data signals to image data voltages in response to the internal control signals to output the image data voltages and outputs a gate driving voltage. The display panel receives the gate driving voltage and the image data voltages to display an image. A screen of the display panel includes a first area and a second area different from the first area. First input image signals corresponding to the first area among the input image signals are processed by I functional blocks (I is smaller than N) among the N functional blocks.
