Abstract
A display apparatus is disclosed. The display apparatus includes a color filter, a first backlight unit, a second backlight unit and a third backlight unit. The first backlight unit, the second backlight unit and the third backlight unit are disposed relative to the color filter and independently emit a first color light, a second color light and a third color light to the color filter respectively. In a brightness mode, the first color light has a first intensity, the second color light has a second intensity and the third color light has a third intensity. In a color mode, when a display image of the display apparatus is biased to a third color corresponding to the third color light, the display apparatus reduces at least one of the first intensity and the second intensity.
Claims18
A display apparatus, comprising:
- a color filter;
- a first backlight unit, a second backlight unit and a third backlight unit, disposed relative to the color filter, configured to independently emit a first color light, a second color light and a third color light to the color filter respectively;
- wherein in a brightness mode, the first color light has a first intensity, the second color light has a second intensity and the third color light has a third intensity;
- in a color mode, when a display image of the display apparatus is biased to a third color corresponding to the third color light, the display apparatus reduces at least one of the first intensity and the second intensity.
A display apparatus, comprising:
- a color filter, disposed corresponding to a display area of the display apparatus;
- a first backlight unit, a second backlight unit and a third backlight unit, disposed corresponding to the color filter, configured to independently emit a first color light, a second color light and a third color light to the color filter respectively;
- wherein when a first display image change occurs in the display area, the first backlight unit, the second backlight unit and the third backlight unit correspondingly adjust at least one of the first color light, the second color light and the third color light emitted by the first backlight unit, the second backlight unit and the third backlight unit according to a first dimming mode;
- when the first display image change is to increase brightness of the display image, the first dimming mode also reduces chromaticness of at least one of the first color light, the second color light and the third color light;
- when the first display image change is to reduce brightness of the display image, the first dimming mode also increases chromaticness of at least one of the first color light, the second color light and the third color light.
