Patent ID: 8624826

Claim:
An outdoor-readable Liquid Crystal Display (LCD), comprising: a liquid crystal panel, the liquid crystal panel comprising an upper substrate, a lower substrate and a liquid crystal layer provided between the upper substrate and the lower substrate; a backlight device, comprising a plurality of red Light-Emitting Diodes (LEDs), green LEDs and blue LEDs; and a light source control device, adapted to adjust the backlight device based on the intensity of ambient light, wherein, when the intensity of ambient light is lower than a predetermined light intensity of the outdoor-readable LCD, a bias voltage of the red LEDs, the green LEDs and the blue LEDs of the backlight device is set to zero, and the red LEDs, the green LEDs and the blue LEDs are switched on in sequence to emit lights with predetermined delays; and when the intensity of ambient light is higher than the predetermined light intensity, the bias voltage of the red LEDs, the green LEDs and the blue LEDs of the backlight device is elevated, and the red LEDs, the green LEDs and the blue LEDs are switched on in sequence to emit lights with predetermined delays.
