DRIVE METHOD FOR ACTIVE TOUCH CONTROL SYSTEM

摘要

The present invention is a drive method for active touch control, relating to a touch control screen, and particularly to an active touch control screen and a drive method thereof. The present invention reveals a drive method for an active touch control system, and proposes a drive signal waveform for each electrode line in the active touch control system and a coordinated detection method, which effectively realizes point-by-point independent detection of sensing electrode units configured in an array. The cooperation of drive signal waveforms on the control electrode line and the detection electrode line is used to distinguish the difference between signals of an operator touching the detection electrode line and touching the detection electrode unit, which avoids a signal which may generate an error action when the operator touches the detection electrode line; and the influence of the display panel used with the active touch control screen in an overlapped way on the touch control signal is eliminated by applying a shielding signal to the shielding electrode.
