Abstract

A portable communication device (1) has a casing (2) with two keypads (3, 4) and a common display (5). The display (5) is pivotally attached to the casing (2) and can be folded between at least a first position, in which the display (5) is located on the same side of the casing (2) as the first keypad (3), and a second position, in which the display (5) is projecting from one edge of the casing (2), thereby making the whole display (5) visible from the same side of the casing (2) as the second keypad (4). The display, in the first position (5), is located in a cavity at the front side of the casing (2), thereby creating an even exterior to the front side of the casing (2). The device (1) has means comprising a controller for presenting the information on the display (5) in alignment with the orientation of the buttons of the keypad (3, 4) currently in use during normal operation of the communication device (1).

Description

Telefona tiebolaget L M Ericsson A PORTABLE COMMUNICATION DEVICE
Field of the Invention
The present invention relates to a portable communication device having a casing provided with first and second keypads arranged on opposite sides of the casing, and a common display for operating the device. The two separate keypads functions as both a telephone and a QWERTY-terminal for sending and receiving sound and alphanumeric and/or graphical information.
Description of the Prior Art
In a communication device, such as a mobile telephone or a mobile station, the common way of writing and sending messages is to use the keypad of the telephone for inputting information. This is unpractical due to few and small buttons of the keypad. By using an additional so- called QWERTY-keypad can an expanded communication function easier to use be achieved. The most common kind of device comprises two halfs of about the same size pivotally attached together by a hinge, each half having a separate display and in which the halfs can be unfolded, whereby the QWERTY-board together with a bigger display compared to the display at the other half are revealed and ready for use. Such a device is disclosed in EP-A1-776 140. Another solution disclosed in EP-A2-472 361 is to join two parts, a portable PC and a mobile telephone, pivotally together as one device with a common display, whereby the PC and the telephone, each having a separate keypad, are placed in one half of the device and the display is placed in the other slightly bigger half of the device. The half with the PC, telephone and adherent keypads covers a part of the display arranged in the other t o o S
