发明名称 DISPLAY DEVICE AND COLOR CONVERSION METHOD
摘要 The display device includes an image display unit including a plurality of pixels each including first to third sub-pixels and a fourth sub-pixel for displaying an additional color component according to an amount of lighting of a self-emitting element; a conversion processing unit that receives a first input signal including first color information for display at a predetermined pixel, where the first input signal is obtained based on an input video signal, the conversion processing unit being configured to outputs a second input signal including second color information with a saturation reduced by an amount of saturation attenuation defined such that saturation variation falls within a predetermined range according to the first color information; and a fourth sub-pixel signal processing unit that outputs, to the image display unit, a third input signal including third color information with red, green, blue components and the additional color component that are converted based on the second color information.

主权项 1. A display device comprising: an image display unit including a plurality of pixels, each of the pixels including a first sub-pixel for displaying a red component according to an amount of lighting of a self-emitting element;a second sub-pixel for displaying a green component according to an amount of lighting of a self-emitting element;a third sub-pixel for displaying a blue component according to an amount of lighting of a self-emitting element; anda fourth sub-pixel for displaying an additional color component different from the respective components of the first sub-pixel, the second sub-pixel, and the third sub-pixel according to an amount of lighting of a self-emitting element, and having a higher luminance or a higher power efficiency to display the additional color component as compared to representation with the first sub-pixel, the second sub-pixel, and the third sub-pixel; a conversion processing unit configured to receive a first input signal including first color information for display at a predetermined pixel, where the first input signal is obtained based on an input video signal and, the conversion processing unit being configured to output a second input signal including second color information in which a saturation of the first color information is reduced by an amount of saturation attenuation defined such that saturation variation falls within a predetermined range according to the first color information; and a fourth sub-pixel signal processing unit configured to output, to a drive circuit that drives the image display unit, a third input signal including third color information with the red component, the green component, the blue component, and the additional color component that are converted based on the second color information in the second input signal.
