Patent ID: 11158678

Abstract:
A display device and a signal processing device for maximum utilization of a color gamut that a display panel can express. A display device includes a display section in which display pixels that each include a first subpixel, a second subpixel, and a third subpixel that emit three-basic-color light and a fourth subpixel that emits non-basic-color light are arranged two-dimensionally; a first signal processing section that expands a video signal being input and corresponding to the basic-color light and adapts the video signal to a color gamut that the display section can express; and a second signal processing section that converts an expanded video signal being the video signal having been expanded into a first signal, a second signal, and a third signal that correspond to the basic-color light and a fourth signal that corresponds to the non-basic-color light, and outputs the signals to the display section.
