Abstract: A device for controlling a color gamut includes: a color mapping module which converts a source image signal, based on a first color gamut look-up table; and a color gamut shift module which sets a second color gamut look-up table, based on a grayscale value determined corresponding to an external factor or user setting. When the color gamut shift module is enabled, the color mapping module converts the source image signal, based on the second color gamut look-up table.

Abstract: A display device and driving method thereof are disclosed. The display device includes a pixel emitting light at a luminance corresponding to an output grayscale value and a color shifter for converting an input grayscale value into the output grayscale value based on output color gamut information. The color shifter includes an offset storage unit storing reference color gamut information and offset information; and a color gamut determination unit that determines the output color gamut information using the reference color gamut information and the offset information when the color shift level corresponds to a value between the reference level and the shift levels, and determines tire output color gamut information using second offset information in which the offset information is inverted and the reference color gamut information when the color shift level is not between the reference level and the shift levels.

Abstract: A display device includes a plurality of pixels, a plurality of gate signal lines extending in a first direction and connected to the plurality of pixels, and a plurality of data signal lines extending in a second direction and connected to the plurality of pixels. The second direction crosses the first direction. The display device further includes a fingerprint sensor configured to detect fingerprint information, and a driver integrated circuit (IC) configured to transmit a plurality of scan signals to the pixels via the gate signal lines, transmit a plurality of data signals to the pixels via the data signal lines, receive the fingerprint information from the fingerprint sensor, and encrypt the received fingerprint information. The display device further includes an application processor configured to receive the encrypted fingerprint information from the driver IC.
