20120062482 | METHOD OF SCANNING TOUCH ON TOUCH SCREEN - The present invention discloses a method of scanning a touch on a touch screen, where drive lines and sense lines of the touch screen form a matrix network. The method includes: instructing the touch screen to enter into a standby mode if no touch has been detected for a time that reaches or exceeds a preset time in a working mode of the touch screen; in the standby mode, scanning A drive lines and sensing B sense lines, said A being an integer greater than or equal to 1 and less than M, and said B being an integer greater than or equal to 1 and less than or equal to N, where M is the total number of the drive lines and N is the total number of the sense lines; instructing the touch screen to enter into the working mode if there is a current fluctuation on the sense lines which are sensed in the standby mode; in the working mode, scanning all the drive lines and sensing all the sense lines. The touch screen is instructed to enter into the energy-saving standby mode if no touch has been detected by the time that reaches or exceeds the preset time, thus achieving the purpose of reducing the power consumption of the touch screen. | 03-15-2012 |
