A USER INTERFACE DEVICE OF A WIRELESS COMMUNICATION DEVICE UTILIZING FLUORESCENT ILLUMINATION

摘要

A user interface device (104, 136) of a wireless communication device (102) in which one or more of the keys (122, 124, 126, 128, 130 and 132) on the user interface are fluorescently illuminated when the user interface is in active mode. One or more keys (302, 104) may include a layer including an opaque film area (304) and a non-opaque area (306), such as an aperture in the opaque film area (404) in the shape of indicia (406), such as a number, letter or function indicator. The opaque film area blocks illumination, and the non-opaque area allows illumination to pass through it. Fluorescent ink at the non-opaque area of a key fluoresces when illuminated in active mode (506), providing fluorescent indicia viewable by a user.
