Abstract
There is disclosed a portable communication device having a microdisplay. A second transmissive display is positioned in front of said first microdisplay.
The device is operable in a first display mode, in which the second display is activated and the microdisplay inactive, and in a second display mode, in which the microdisplay is activated, and the second display rendered transparent so that the microdisplay can be viewed through the second display.
This has the advantage of considerably reducing the total surface area and/or volume of the device needed for the display, and thus aids the development of smaller devices.
