Abstract
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.
