    摘要: A high transmittance brightness enhanced optical element for backlight modules and liquid crystal display device is disclosed. The brightness enhanced polarizing optical element comprises a reflective polarizer film, a phase retardation film, and a polarization enhancement film. The reflective polarizer film provides a function of selectively reflecting right-handness circularly polarized light or left-handness circularly polarized light and will transmit the other one of them. The one was selectively reflected will be recombined with the light source or the backlight and re-direct toward the reflective polarizer. The portions of the reflective light will be recombined with the fresh light from the light source as above and the processes repeatedly. As a result, almost all of the light transmit the reflective polarizer and in the same circular polarization. The light is then transmitted the phase retardation film and converted to a polarized light with another optical axis.

    摘要: A wire grid polarizer with double metal layers for the visible spectrum. Parallel dielectric layers having a period (p) of 10˜250 nm and a trench between adjacent dielectric layers overlie a transparent substrate. A first metal layer having a first thickness (d1) of 30˜150 nm is disposed in the trench. A second metal layer having a second thickness (d2) of 30˜150 nm and a width (w) overlies on the top surface of each dielectric layer. The first and second metal layers are separated by a vertical distance (l) of 10˜100 nm. The first thickness (d1) is the same as the second thickness (d2). A ratio of the width (w) to the period (p) is 25˜75%.

    摘要: An illumination device including a base, at least one LED light source and a first diffusing element is provided. The base has a supporting plane. The LED light source disposed on the supporting plane has a light emitting surface substantially parallel to the supporting plane. The first diffusing element disposed on the supporting plane is a hollow column surrounding the LED light source. An inner diameter width of the first diffusing element is gradually reduced outward from the base. The first diffusing element has a rough surface comprising a plurality of surface structures.
