Abstract
The present invention provides a touch sensitive method including: transmitting a driving signal via a first driving electrode of a touch screen during a first blanking interval; and sensing the driving signal via a plurality of sensing electrodes of the touch screen during the first blanking interval for detecting an external conductive object on or near the first driving electrode.
Claims21
A touch sensitive method comprising:
- during a first blanking interval, transmitting a driving signal via a first driving electrode of a touch screen;
- and
- during the first blanking interval, detecting an object touching or in proximity to the first driving electrode by measuring the driving signal via a plurality of sensing electrodes of the touch screen.
A touch sensitive processing apparatus, comprising:
- a driving circuit connected to a plurality of driving electrodes of a touch screen;
