  • Bi-stable projection screen
    Patent number: 7839568
    Abstract: 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.

  • Modified acrylic resin and optical diffusing composition utilizing the same
    Publication number: 20080157034
    Abstract: A modified acrylic resin. The modified acrylic resin comprises a transparent resin and an acrylic acid monomer having a cyclic group, and the modified acrylic resin has a low moisture adsorption. Additionally, the modified acrylic resin can be incorporated with light scattering particle and light stabilizer to provide an optical diffusing composition for use in backlight module of LCD panels.
