Abstract (en)
[origin: WO9918552A1] A communication device such as a pager (100) includes a color display (106). An icon (302), a portion of the display (106) or another attribute of the display, such as the display's backlight, changes color depending on the age of any message which has been received by the pager (100) but has not been presented to the user of the communication device. If the message is read or heard by the user, as determined by the message being presented on the display or annunciate on a speaker, in the preferred embodiment, the display returns to displaying the icon (302) in conventional black color. If a message remains not presented to the user, the color of icon (302) changes over time according to the age of the message which has yet to be presented to the user.
