A wireless communication device having a display screen with a holographic overlay. The holographic overlay includes an image that is visible when the display screen is viewed at predetermined angles. The holographic overlay may provide additional surface on the wireless communication device for marking and advertising, and may also provide security by preventing unintended viewers from seeing characters on the display screen. In one embodiment, the display screen includes a character screen, a lens, and a holographic overlay.

DETAILED DESCRIPTION The present invention includes a holographic overlay positioned proximate a display screen of a wireless communication device.
The holographic overlay is positioned such that it has a first appearance when viewed at a first angle, and a second appearance when the display screen is viewed at a second angle.
The holographic overlay may be substantially transparent at the first angle such that display characters appearing on the display screen are visible.
When viewed at the second angle, the holographic overlay may substantially obscure the display characters.
The holographic overlay may provide previously unavailable surface area on the wireless communication device for advertising and other branding materials.
The holographic overlay may also prevent an unintended viewer from seeing characters displayed on the display screen.
