Touch Sensing System and Method of Driving the Same
First Claim
1. A touch sensing system comprising:
- a touch screen integrated display panel provided with a plurality of touch sensors and a plurality of pixels;
a timing controller configured to time-divide one display frame into a plurality of touch periods and a plurality of display periods;
a microcontroller unit configured to divide a sensing mode of the plurality of touch sensors into a full scan mode and a local scan mode; and
a touch integrated circuit (IC) configured to sense a finger touch input of the touch sensors through the touch periods in the full scan mode and time-division sense a finger touch input and a pen touch input of the touch sensors through the touch periods in the local scan mode.
