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.
