    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 reflective-type diffraction grating structure for use in color display devices such as liquid crystal displays (LCDs). It contains: (1) a plurality of micro-lenses each having a smooth top surface and a blazed zig-zag-shaped grating surface at the bottom; (2) an optical coating formed below the zig-zag-shaped grating surface; and (3) a reflective member formed below the optical coating. With the cooperative actions of the zig-zag-shaped grating surface, the optical coating layer, and the reflective member, an incident light, when reflected, is separated into repeated sequences of red, green, and blue color components and a black matrix segregating the red, green, and blue color components. A sequence of micro-light valves are placed in the path of the reflected incident light to block the undesired color components. The reflective-type diffraction grating structure dispenses with the need for the various layers of color filters. As a result, it improves the brightness of the image and reduces power consumption, as well as reducing the manufacturing cost.

Nanoimprint lithography, a low cost technology, includes two alternatives, i.e., hot-embossing nanoimprint lithography and UV-curable nanoimprint lithography. Manufacture steps includes providing a substrate with a polymer material layer disposed thereon. A plurality of lands and grooves are formed in the polymer material layer, and a first metal layer and a second metal layer are disposed on the surfaces of the lands and grooves, respectively. Finally, a color filter having a bi-layer metal grating is obtained.

    摘要: A bi-stable projection screen includes a light diffusion unit and a bi-stable display unit stacked together. The bi-stable display unit, when actuated, selectively operates in a first mode or a second mode. When operating in the first mode (e.g., a transmission mode or a reflection mode), the bi-stable display unit receives a projection light from a front projection or a rear projection, and emits the projection light after modulation. When operating in the second mode (a non-transmission mode or a non-reflection mode), the bi-stable display unit is a pattern to become a part of a scene. The light diffusion unit receives and diffuses the modulated projection light to be perceived by human eyes.
