  • Optical lens and backlight module incorporating the same
    Patent number: 9146018
    Abstract: An optical lens is adapted for used in a light source that has an optical axis, and includes a light-entering surface, a light-exiting surface, and a modified reflection surface. The light-entering surface has two first ends. The light-exiting surface defines a light-exiting surface profile that is concave toward the light source and that has two second ends. The modified reflection surface defines two modified reflection surface profiles. Each of the first ends is connected to a corresponding one of the second ends by a corresponding one of the modified reflection surface profiles. The modified reflection surface profiles are concave in the same direction as the light-exiting surface profile.

  • BACKLIGHT MODULE
    Publication number: 20140022762
    Abstract: A backlight module includes: a light diffusion unit including a diffusing plate and a plurality of light diffusion elements formed on the diffusing plate, each of the light diffusion elements having a first diffusion pattern which has a first light-permeable region and a first light-blocking region, and a second diffusion pattern which surrounds the first diffusion pattern and which has a continuous second light-permeable region and a plurality of second light-blocking regions distributed in the continuous light-permeable region; and a light source disposed adjacent to the light diffusion unit and emitting light beams to the light diffusion unit.
