  • Publication number: 20110128255
    Abstract: A light source module includes a light source, a light guide unit, an opaque reflective element, a reflective unit, and a patterned light-absorbing element. The light guide unit has first and second surfaces, a light incident surface, and third and fourth surfaces. A beam from the light source enters the light guide unit through the light incident surface and is transmitted to outside through the first surface. The opaque reflective element covers a portion of the first surface adjacent to the light incident surface. The patterned light-absorbing element is disposed on a surface of the reflective unit. A portion of the patterned light-absorbing element is between a portion of the third surface adjacent to the light incident surface and the reflective unit. Another portion of the patterned light-absorbing element is between a portion of the fourth surface adjacent to the light incident surface and the reflective unit.

  • Publication number: 20110080374
    Abstract: An optical touch apparatus includes at least one light source, at least one light guide unit, at least one optical detector, and a light reducing structure. The light source is disposed beside a display area of a display and capable of providing a light beam. The light guide unit is disposed beside the display area and in a transmission path of the light beam. The light guide unit has a first surface, a second surface, and a light incident surface. The light beam is capable of entering the light guide unit through the light incident surface and being transmitted to a sensing space in front of the display area through the first surface. The optical detector is disposed beside the display area. The light reducing structure covers a portion of the first surface adjacent to the light incident surface.
