METHOD OF UPDATING BASELINE OUTPUT VALUES OF TOUCH PANEL
First Claim
1. A method of updating baseline output values of a touch-sensing panel, the touch-sensing panel comprising a plurality of first-directional lines and a plurality of second-directional lines, the first-directional line and second-directional lines arranged intersecting one another, so as to form a sensing grid with a plurality of sensing nodes, the method comprising the steps of:
- performing a first scan when the touch-sensing panel is not touched, so as to obtain a plurality of first baseline output values on the sensing nodes;
performing a second scan after the touch-sensing panel is touched, so as to obtain a plurality of touch output values on the sensing nodes; and
updating the baseline output values on the sensing nodes based on a threshold, the first baseline output values, and the touch output values.

Abstract
An updating method for baseline output values of a touch-sensing panel is disclosed. The touch-sensing panel includes a plurality of X-directional lines and a plurality of Y-directional lines. The X-directional lines and Y-directional lines are arranged intersecting one another so as to form a sensing grid with a plurality of sensing nodes. The method includes the following steps: performing a first scan when the touch-sensing panel is not touched so as to obtain a plurality of first baseline output values; performing a second scan after the touch-sensing panel is touched so as to obtain plurality of touch output values; and updating the baseline output values on the sensing nodes based on a threshold, the first baseline output values and the touch output values.
