摘要： The backlight module includes a reflective sheet, at least one point light unit with a dish lens on the reflective sheet. The dish lens has a light-permeable surface formed on the bottom of the dish lens, a light-reflecting surface formed on top of the dish lens, two smooth curve surfaces formed on two side of the dish lens for connecting the light-reflecting surface and the light-permeable surface, and a light-scattering surface on the center of the light-reflecting surface. The profile of the light-permeable surface and the light-reflecting surface are a substantially concave shape. The profile of the light-scattering surface is a substantially convex shape. A light emitting diode (LED) device includes a light emitting semiconductor device and a dish lens encapsulating the light emitting semiconductor device. The dish lens allows the light beams emitted by the LED to diffuse more uniformly, resulting in a more uniform backlight emission.

摘要： A white-light emitting device comprising a first PRS-LED and a second PRS-LED. The first PRS-LED has a primary light source to emit blue light and a secondary light source to emit red light responsive to the blue light; and the second PRS-LED has a primary light source to emit green light and a secondary light source for emitting red light responsive to the green light. Each of the primary light sources is made from an InGaN layer disposed between a p-type GaN layer and an n-type GaN layer. The secondary light sources are made from AlGaInP. The primary light source and the secondary light source can be disposed on opposite sides of a sapphire substrate. Alternatively, the second light source is disposed on the n-type GaN layer of the primary light source. The second light sources may comprise micro-rods of AlGaInP of same or different compositions.

摘要： The present application describes a system and method for converting randomly polarized light into linearly polarized light without absorption loss to improve the brightness of a liquid crystal display system. According one embodiment, the liquid crystal display system includes an optical converter module configured to convert the randomly polarized light into linearly polarized light. The optical converter module is configured to convert the polarization of a first polarized component of the randomly polarized light to be substantially similar to a second polarized component. The optical converter module transmits the first and second polarized components having substantially similar polarization.
