Abstract

A display requires a backlight that consumes significant power, shortening the battery life. If a holster is used, the backlight turns on when the device is removed from the holster and times-out after no activity has been detected. No activity means no key presses. This does not cover reading the information on the screen for a longer time period than the timeout. Also, if the user does not use a holster, a key or a combination of keystroke are required to activate the display. By adding a touch sensor or proximity sensor, the display backlight can be turned on based on the user’s picking up the device and then remaning on until the user is no longer holding the unit.
