Abstract:
An LCD device is disclosed which includes: at least one sensor module configured to sense an amount of external light; a liquid crystal display panel configured to display images; at least one light source module disposed under the liquid crystal display panel and configured to emit light; and at least one light guide plate configured to convert light from the at least one light source module into two-dimensional light and apply two-dimensional light to the liquid crystal display panel. The at least one light source module includes infrared LEDs and visible LEDs which are selectively driven according to a sensed light quantity sensed by the at least one sensor module and allow infrared light and visible light to be selectively emitted.
Abstract:
Provided are a backlight unit and a display device having the same. The backlight unit includes a case having an opening, at least one lamp assembly disposed on a side surface of the case and including a light source, an optical transreflective unit on the case, the optical transreflective unit transmitting a portion of first light passing through the opening and reflecting a portion of second light generated from the light source, and an optical sheet including a first diffusion unit on the optical transreflective unit.
