Abstract
Disclosed is a display apparatus. The display apparatus includes a liquid crystal panel including a plurality of subpixels, a backlight unit including a white light source and a blue light source, and a processor configured to adjust the blue light source to emit light and to adjust an aperture ratio of at least one of the plurality of subpixels based on a color temperature of the white light source and a target color temperature.
Claims17
A display apparatus comprising:
- a liquid crystal panel including a plurality of subpixels;
- a backlight unit comprising backlight circuitry and including a white light source and a blue light source;
- and
- a processor configured to:
- identify a difference between a color temperature of the white light source and a target color temperature;
- and
- control the display apparatus to adjust a light emitting intensity of the blue light source and adjust an aperture ratio of at least one of the plurality of subpixels based on the identified difference between the color temperature of the white light source and the target color temperature.
A method of driving a display apparatus comprising a liquid crystal panel including a plurality of subpixels and a backlight unit including a white light source and a blue light source, the method comprising:
- identify a difference between a color temperature of the white light source and a target color temperature based on comparison between the color temperature of the white light source and the target color temperature;
- and
- adjusting a light emitting intensity of the blue light source and adjusting an aperture ratio of at least one of the plurality of subpixels based on the identified difference between the color temperature of the white light source and target color temperature.
A non-transitory computer readable recording medium storing computer instructions which, when executed by a processor of a display apparatus comprising a liquid crystal panel including a plurality of subpixels and a backlight unit including a white light source and a blue light source, cause the display apparatus to perform operations including:
- identifying a difference between a color temperature of the white light source and a target color temperature based on comparison between the color temperature of the white light source and the target color temperature;
- and
- adjusting a light emitting intensity of the blue light source and an aperture ratio of at least one of the plurality of subpixels based on the identified difference between the color temperature of the white light source and target color temperature.
