ELECTRONIC DEVICES HAVING A TOUCH SCREEN AND METHOD FOR STARTING THE ELECTRONIC DEVICES
First Claim
1. An electronic device comprising:
- a display having a capacitive touch screen, the touch screen comprising a substrate, an electricity conductive layer, and a linear layer, stacked on one another in that order, at least two electrodes being coated on two perpendicular sides of the linear layer, the electrodes are electrically connected to the main processor, voltages of the electrodes being the same;
a chip controller;
a power supply electrically connected with and controlled by the chip controller; and
a main processor electrically connected to the touch screen, and the chip controller, the main processor being used to store a start operational input including at least one of a predetermined touched area, a predetermined touched duration, and a predetermined number of touched times and calculate a touched signal including at least one of touched position, touched duration, and number of touched times that the touch screen is touched, the main processor being used to further compare the touched signal with the start operational input to decide whether to send a start instruction to the chip controller to start the electronic device.

Abstract
An exemplary electronic device (10) comprises a display (11), a chip controller (131), a power supply (14) and a main processor (12). The display has a capacitive touch screen (111). The power supply is electrically connected with and controlled by the chip controller. The main processor is electrically connected to the chip controller. The main processor is used to store a start operational input and calculate a touched signal that the touch screen is touched. The main processor further compares the touched signal with the start operational input to decide whether to send a start instruction to the chip controller to start the electronic device. The present invention further provides a method for starting the electronic device.

11. A method for starting an electronic device comprising:
-
providing an electronic device comprising a display, a chip controller, a power supply and a main processor, the power supply electrically connected with and controlled by the chip controller, the main processor electrically connected with the chip controller, the display having a capacitive touch screen, the touch screen comprising a substrate, an electricity conductive layer, and a linear layer, lying on one another in that order, at least two electrodes being coated on two perpendicular sides of the linear layer, the electrodes are electrically connected to the main processor, voltages of the electrodes being the same; inputting a start operational input including at least one of a predetermined touched area, a predetermined touched duration, and a predetermined number of touched times into the main processor; touching the touch screen with a conductive object; a current generated and flowing through each of the electrodes because of capacitive coupling between the conductive layer and the conductive object, and the main processor receiving signals of the currents generated and flowing through the electrodes; the main processor calculating a touched signal including touched areas, touched duration and number of touched times according to the signals of the currents, and the main processor comparing the touched signal with the start operational input;
the main processor sending a start instruction to the chip controller and the chip controller making the power supply applying power to start the electronic device if the touched signal being consistent with the start operational input. - View Dependent Claims (12, 13, 14, 15, 16, 17)
