COMMUNICATION DEVICE WITH COMBINED INPUT AND DISPLAY DEVICE
First Claim
1. Communication device comprising a combined input and display device for character input and image display, a control unit and a proximity sensor, wherein the proximity sensor and the control unit are 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.

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 The second display mode is kept until the pointer is withdrawn more then a second predetermined distance from the display device at which occasion the control unit is configured to generate a second control signal for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.
