Abstract: A phase delay element includes a brightness enhancement layer intermediate a reflection layer and an artificial light. The brightness enhancement layer is defined by a first surface and an opposite second surface. The first surface faces the reflection layer. A first light from the artificial light is incident on the second surface. A phase of the first light is delayed by about ¼ phase (λ/4) so that a second light is emitted from the first surface toward the reflection layer. The second light is reflected from the reflection layer so that a third light is emitted from the reflection layer toward the first surface. A phase of the third light is delayed by about ¼ phase (λ/4) so that a fourth light is emitted from the second surface. Therefore, a portion of the artificial light, which is reflected from the reflection layer, is recycled to improve a luminance of an LCD apparatus.

Abstract: A method for controlling a backlight luminance in which a reference voltage is set, a sampling voltage is generated based on the reference voltage, and a net photo current signal is generated by a photo current sensing element and a dark current sensing element. The net photo current signal is generated independently of temperature variations. A luminance control signal is generated based on the sampling voltage. The luminance of the backlight assembly is controlled using the luminance control signal. Therefore, variation of the luminance of the backlight assembly may be minimized, although external luminance, temperature, and variation between different photo sensors, the deterioration of the elements, and the like, may be changed.
