Abstract:
1. A light guide panel for backlighting a device, the light guide panel comprising: a plate including a plurality of optical fibers for dispersing light through the plate to illuminate the plate and provide a backlight for the device, the plurality of optical fibers being completely within the plate; and a light-emitting diode (LED) coupled to the plate for providing the light dispersed by the plurality of optical fibers, the light-emitting diode being located in a central portion of the plate such that the light-emitting diode (LED) does not touch an edge of the plate, wherein an opaque portion of the device covers the light-emitting diode (LED) in the central portion of the plate such that when the light-emitting diode (LED) is illuminated, the light from the light-emitting diode (LED) is more evenly distributed throughout the plate, the opaque portion of the device being a user input button of the device.
