    摘要: A light guide includes a light interface surface, top and bottom surfaces, a surface feature pattern, and a cut line. The light interface surface receives light into the light guide from a light source. The light received through the light interface surface reflects according to total internal reflection (TIR) within the light guide between portions of the top and bottom surfaces. The surface feature pattern disrupts the TIR and scatters at least some of the light outside of at least one surface of the top and bottom surfaces. The cut line redirects at least some of the light from a first direction to a second direction within the light guide. The first direction is a direction other than towards the surface feature pattern, while the second direction is a direction substantially towards the surface feature pattern. The light guide may back-illuminate an optical keypad with a plurality of push buttons.

    摘要: An input device and display apparatus with multi-light segments has been disclosed. The input device may comprise a rigid light guide layer having alignment structures that define the rigid light guide layer into multiple light segments, a plurality of first layer flexible light guide films and a plurality of second layer flexible light guide films. The alignment structures may be formed together when making the rigid light guide layer in an injection molding process. By coupling multiple light sources into each of the light guides, the display may be configured to display multiple color and multiple symbols, independently. In another embodiment, the light guide may be utilized in a display apparatus without a LCD.
