According to an aspect, a display device includes: an image display panel; and a plurality of signal processing circuits that are responsible for respective regions in the image display panel, that convert an input value of an input HSV color space of an input signal to each of their own responsible regions into an extension value of an extended HSV color space to generate an output signal of the extension value for the image display panel. The signal processing circuits decide an extension coefficient αA for the image display panel in its entirety in a cooperative manner. The signal processing circuit, regarding its own responsible region, calculates an output signal of each of a first sub-pixel, a second sub-pixel, third sub-pixel, and a fourth sub-pixel. |

1. A display device comprising:
an image display panel in which pixels are arrayed in a two-dimensional matrix, each of the pixels including a first sub-pixel that displays a first color, a second sub-pixel that displays a second color, a third sub-pixel that displays a third color, and a fourth sub-pixel that displays a fourth color; and a plurality of signal processing circuits that are responsible for respective regions in the image display panel, that convert an input value of an input HSV color space of an input signal to each of their own responsible regions into an extension value of an extended HSV color space that is extended by the first color, the second color, the third color, and the fourth color to generate an output signal of the extension value, and that output the generated output signal to the image display panel, wherein the signal processing circuits decide an extension coefficient αA for the image display panel in its entirety in a cooperative manner, each of the signal processing circuits, regarding its own responsible region, calculates: an output signal of the first sub-pixel based on at least an input signal of the first sub-pixel and the extension coefficient αA to output the output signal to the first sub-pixel; an output signal of the second sub-pixel based on at least an input signal of the second sub-pixel and the extension coefficient αA, to output the output signal to the second sub-pixel; an output signal of the third sub-pixel based on at least an input signal of the third sub-pixel and the extension coefficient αA, to output the output signal to the third sub-pixel; and an output signal of the fourth sub-pixel based on the input signal of the first sub-pixel, the input signal of the second sub-pixel, and the input signal of the third sub-pixel, to output the output signal to the fourth sub-pixel, one of the signal processing circuits operates as a master of other ones of the signal processing circuits, the other ones of the signal processing circuits operate as a slave of the signal processing circuit that operates as a master, each of the signal processing circuits calculates an extension coefficient for an input signal to its own responsible region, each of the signal processing circuits that operate as a slave transmits an extension coefficient calculated on its own to the signal processing circuit that operates as a master, and the signal processing circuit that operates as a master decides the extension coefficient αA based on an extension coefficient calculated on its own and an extension coefficient received from each of the signal processing circuits that operate as a slave, and transmits the extension coefficient αA to each of the signal processing circuits that operate as a slave. |
