    Abstract: 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.

    Abstract: A lighting system is described. One embodiment of the lighting system includes a light guide, a first lighting device, and a second lighting device. The light guide receives light along a transmission interface. The first lighting device has a first plurality of lighting elements coupled to a first substrate between a first pair of reflector walls. The first substrate and the first pair of reflector walls define a first exposed side of the first lighting device. The second lighting device has a second plurality of lighting elements coupled to a second substrate between a second pair of reflector walls. The second substrate and the second pair of reflector walls define a second exposed side of the second lighting device configured to match the first exposed side of the first lighting device. Using lighting devices without sidewalls illuminates a diffusion panel so that there are no dark spots.

    Abstract: A light guide display includes a printed overlay layer, a first light guide layer, and a second light guide layer. The printed overlay layer includes an input region with a symbol that is at least partially translucent. The first light guide layer is disposed on a back side of the printed overlay layer to illuminate the symbol of the printed overlay layer in response to illumination of the first light guide layer. The second light guide layer is disposed on a front side of the printed overlay layer, opposite the first light guide layer. The second light guide layer includes a separate symbol that is distinct from the symbol of the printed overlay layer. The second light guide layer illuminates the separate symbol of the second light guide layer in response to illumination of the second light guide layer.
