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.
Claims19
A touch sensitive method comprising:
- during a first blanking interval, transmitting a driving signal including a first pseudo-random number (PN) code via a first driving electrode of a touch screen;
- during the first blanking interval, transmitting the driving signal including a second PN code via a second driving electrode of the touch screen;
- and
- during the first blanking interval, detecting an object touching or in proximity to the first driving electrode and the second driving electrode by measuring the driving signal via a plurality of sensing electrodes of the touch screen.
