Abstract:
A liquid crystal display device may include a backlight unit for providing light for the display. A backlight unit may include light modules. The light modules include colored LEDs surrounded by a first lens for refracting the light from the LEDs. A second lens surrounds the first lens for further refraction of the light to improve brightness and the uniformity of the light.
