Abstract
A display device includes a display layer, a control unit, a color sensor and a light guide plate (LGP) arranged on the display layer. A light emitting module includes three light emitters configured for emitting red, green and blue light, into the LGP through the lateral surface. The control unit determines whether the detected intensities of the red, green and blue light components in the ambient light are in a predetermined proportion, and to turn on the corresponding light emitters to compensate the red, green or blue light so as to maintain the intensities of the red, green and blue light components in the ambient light to be in the predetermined proportion.
