  • Communication device and display blanking control method therefor
    Patent number: 5881377
    Abstract: A method and apparatus control blanking of a display (106) in a communication device (100) such as a battery powered radiotelephone. The communication device (100) includes a clock operated blanking timer 317. When the blanking timer 317 elapses, the communication device (100) blanks the display (106) a predetermined time after a key press of a keypad (108). A switch (310) detects when the communication device (100) is in use. In response to this detection, the communication device (100) maintains supply of operating power to the display (106), overriding the blanking timer 317. When a user is holding the communication device (100) adjacent to the user's head, an earpiece sensor (312) provides an indication of this condition. In response to the indication, the display (106) is immediately blanked to conserve operating power in the battery (124).
