Abstract: A liquid crystal display has a backlight module and an indicator. The indicator is used to detect the light brightness of the backlight module, and announces a warning when the light brightness is lower than a predetermined value. The indicator has at least one color light detection unit that includes a detector, an analog-to-digital converter (ADC), a controller and a warning display. The detector detects the brightness of a color light from the backlight module to generate a light brightness voltage. The ADC converts the light brightness voltage into a digital signal. The controller determines whether the brightness of the color light is lower than the predetermined value or not according to the digital signal. When the brightness of the color light is lower than the predetermined value, the controller makes the warning display announce the warning.
