PORTABLE ELECTRONIC DEVICE AND METHOD FOR WAKING UP THE SAME FROM SLEEP MODE THROUGH TOUCH SCREEN
First Claim
1. A portable electronic device, comprising:
- a central processor, capable of operating in a sleep mode and a normal operation mode;
a display, having a display area for displaying information;
a touch screen, overlaid on the display and having a first touch area overlaid on the display area of the display, a second touch area extending to outside of the display area, and at least one electrode, wherein when the central processor operates in the sleep mode and one of the first and the second touch areas senses a touch, the at least one electrode generates a touch signal; and
a micro processing unit, electrically connected to the at least one electrode, for determining whether the touch is sensed by the first or the second touch area according to the touch signal, wherein when the touch is sensed by the second touch area, the micro processing unit outputs a wake-up signal to the central processor, so as to switch the central processor from the sleep mode to the normal operation mode.

Abstract
A portable electronic device including a touch screen, a micro processing unit, a central processor and a display is provided. The central processor can operate in a normal operation mode or a sleep mode. The touch screen overlays the display, and includes a first touch area, a second touch area and at least one electrode. When the central processor operates in the sleep mode and one of the first and second touch areas senses a touch, the at least one electrode generates a touch signal. The micro processing unit determines whether the touch is sensed by the first or the second touch area according to the touch signal. If the touch is sensed by the second touch area, the micro processing unit outputs a wake-up signal to the central processing unit, so as to switch the central processor from the sleep mode to the normal operation mode.

12. A method for waking up a portable electronic device from a sleep mode through a touch screen, the portable electronic device having a central processor, a touch screen and a micro processing unit, and the touch screen having a first touch area and a second touch area, the method comprising:
-
sensing a touch by one of the first and the second touch areas; generating a touch signal when the touch is sensed; according to the touch signal, determining, by the micro processing unit, whether the touch is sensed by the first or the second touch area and outputting a wake-up signal if the touch is sensed by the second touch area; and switching the central processor from the sleep mode to a normal operation mode according to the wake-up signal. - View Dependent Claims (13, 14, 15)
