Unlocking Mechanism for a Touch Screen Device
First Claim
1. A method for unlocking a touchscreen device, comprisingdefining an area on a touchscreen as an unlocking spot;
- said unlocking spot comprising a location and a size;
defining a threshold of length of time;
determining whether said unlocking spot is touched;
counting a length of time when said unlocking spot is touched;
determining whether said length of time is equal to or larger than said threshold of length of time;
sending a first signal to a detection unit when said length of time is equal or larger than said threshold of length of time;
sending an activation signal to a micro control unit (MCU) of said touchscreen device;
activating said MCU; and
unlocking said touchscreen device.

Abstract
A method for unlocking a touchscreen device comprises no involvement of pressing a physical button of the touchscreen device. Rather, it employs a pre-defined touchscreen area as the unlocking spot. The location and size of this unlocking spot can be redefined by a user. When this spot is touched by a finger, a counter will start to count numbers. When it passes a pre-defined number threshold, the activation signal will be sent to a micro control unit (MCU) to activate the MCU. In this way, the touchscreen device is unlocked. In addition, a power saving circuit is provided to execute such unlocking function and reduce power consumption.
