Abstract
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.
