ESTIMATING METHOD FOR INTENSITY OF PRESSURE ON TOUCH INPUT APPARATUS AND TOUCH INPUT APPARATUS FOR SENSING INTENSITY OF PRESSURE BY TOUCH INPUT

摘要

A method of measuring the strength of a touch pressure in a touch input device includes measuring a first capacitance using a means for measuring a strength of a touch pressure in a state where the touch input device does not detect a touch input on the touch panel, Wherein the touch input device senses a touch input through the touch panel, and when the touch input device senses a touch input on the touch panel, measures a second electrostatic capacity for measuring the strength of the touch pressure using the means And measuring a change in capacitance based on a difference between the second capacitance and the first capacitance when the first capacitance is equal to or greater than a reference value.
