Abstract

Surface-mounted custom labels for portable elec- tronic devices, e.g., selective call receivers may be used, for example, to record a serial number, to iden- titji a manufacturer or service provider, and for secu- rity purposes, such as theft prevention A problem with surface-mounted custom labels is the amount of housing surface space they require. Today's mini- ature portable devices often contain relatively large displays and many user-control buttons, and thus ofien do not have sufficient unused housing surface space to accommodate a surface-mounted custom label. A second problem with surface-mounted cus- tom labels is that they easily can be removed or altered. This problem can be particularly important in the case of labels used to identify a product for warranty or security purposes.

BACKLIGHTED ELECTRONIC DISPLAY WITH LABEL ELEMENT

  Surface-mounted custom labels for portable elec- tronic devices, e.g., selective call receivers may be used, for example, to record a serial number, to iden- titji a manufacturer or service provider, and for secu- rity purposes, such as theft prevention A problem with surface-mounted custom labels is the amount of housing surface space they require. Today's mini- ature portable devices often contain relatively large displays and many user-control buttons, and thus ofien do not have sufficient unused housing surface space to accommodate a surface-mounted custom label. A second problem with surface-mounted cus- tom labels is that they easily can be removed or altered. This problem can be particularly important in the case of labels used to identify a product for warranty or security purposes.

  Referring to Figure 1, an isometric assembly view of a display depicts a display element 102, the dis- play element 102 being substantially transparent, such as a well-known liquid crystal display (LCD) ele- ment, and a backlighting element 104, such as a conventional electroluminescent (EL) panel. Positioned between the backlighting element 104 and the display element 102 is a substantially trans- parent substrate 106 on which is positioned a light- filtering pattern 108 having a predetermined geom- etry. A preferable material for the substantially transparent substrate 10...
