Abstract

The present invention relates to a communication device comprising a combined input and display device for character input and image display and a method for controlling said character input and image display. The device comprises a control unit and a proximity sensor arranged in such a way that the sensor is able to detect when a pointer comes within a first predetermined distance from the input and display device and that the control unit is configured to generate a first control signal for changing display modes, from a first to a second display mode, upon detection of the pointer. The second display mode is kept until the pointer is withdrawn more then a second predetermined distance from the display device at which occasion the control unit is configured to generate a second control signal for changing display modes, from the second to the first display mode.

Description

technical field [0001] The present invention relates to the field of communication devices, and more particularly, to a communication device including a combined input display unit for character input and image display. In addition, the present invention also relates to a method for controlling character input and display in a communication device. Preferably, the present invention is used with a communication device having a limited area for display. Background technique [0002] A communication device such as a cellular telephone may provide a man-machine interface (MMI), such as a physical keyboard or keypad and some kind of display, such as a conventional TFT display, a combined TFT virtual keyboard / display, or any other type of input and display combination. [0003] The most widely used alphabetic keyboard layout is the QWERTY layout, but many other layouts exist, such as the AZERTY or DVORAC layouts. Alphabetic keyboard layouts as described above are often combined...
