Displaying "wallpaper" on a mobile telephone display

A mobile phone with a display screen capable of displaying a main display "on top" of a background or wallpaper display is provided. A display compiler combines the main display with the background display such that the main display appears on top of the background. The background can be updated at regular intervals so that it can be animated. A method for compiling the composite display is also provided. The main display and background displays are combined using an OR function. Furthermore, the contrast of the foreground can be set to a value higher that that of the background image.
