Abstract: An image display device includes an image display unit including first pixels including sub-pixels of three or more colors in a first color gamut, and second pixels including sub-pixels of three or more colors in a second color gamut different from the first color gamut; a processing unit that determines an output of the sub-pixels of the first pixel based on a combined component of a first component and an out-of-color gamut component, and determines an output of the sub-pixels of the second pixel based on a third component by eliminating the out-of-color gamut component from a second component; and a determination unit that determines whether the input image signal corresponds to an edge of an image. When the input image signal corresponds to the edge of the image, the processing unit causes the out-of-color gamut component not to be reflected in an output of the first pixel.

Abstract: A display device includes: an image display panel including a plurality of pixels each including a first sub-pixel, a second sub-pixel, and a third sub-pixel that display a first color to a third color; and a signal processing unit. The signal processing unit stores an expanded color space, acquires an expansion coefficient for expanding a color displayed by the image display panel to a color that can be extended in the expanded color space, obtains output signals of the first sub-pixel to the third sub-pixel based on at least input signals of the first sub-pixel to the third sub-pixel and the expansion coefficient, and outputs the output signals to the first sub-pixel to the third sub-pixel. The expanded color space is a color space that can extend a color the brightness of which is higher than brightness in a standard color space.

Abstract: An image display device comprises an image display unit including first pixels and second pixels arranged in a staggered manner, the first pixels including sub-pixels arranged in a matrix in a first color gamut and second pixels including sub-pixels arranged in a matrix in a second color gamut different from the first color gamut; and a processing unit that determines an output of the sub-pixels corresponding to an input image signal. When sub-pixels including same color component are continuously lit in a straight line and there is a difference between outputs from adjacent sub-pixels including the same color component, the processing unit determines the output of the sub-pixels in the first pixel based on the first component after an adjustment component is eliminated, and determines the output of the sub-pixels included in the second pixel based on the second component and the adjustment component.
