摘要: Backlighting methods and apparatuses to backlight a device. The backlighting apparatus includes a flexible light guide, a light source, and a housing. The light source is disposed adjacent to a transmission interface of the flexible light guide to illuminate the flexible light guide. The housing at least partially encloses the flexible light guide and the light source. A surface area of the flexible light guide is visible through the housing. By using a flexible light guide to backlight the device, the size of the device is reduced compared to conventional devices. Alternatively, the device may accommodate additional components. Other advantages also may be achieved.

摘要: A light guide for an optical keypad is described. The 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.

摘要: A tubular light source having a semiconductor light source and a tube is disclosed. The tube includes a transparent medium, the tube having a side tube surface, a center curve, one end surface, a length, and a maximum cross-sectional dimension. The tube includes scattering centers that cause light traveling in the tube to be reflected at angles such that the reflected light leaves the tube through the side tube surface. The semiconductor light source is positioned to emit light into the tube within a cone of angles such that the light will not leave the side tube surface in the absence of the scattering centers. The scattering centers can be dispersed in the transparent medium or located on the side tube surface. The transparent medium can be rigid or flexible.

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.
