STRUCTURE OF TOUCH INPUT FOR ACQUIRING LOCATION AND INTENSITY OF FORCE, APPARATUS THEREWITH AND ACQUIRING METHOD THEREOF

摘要

PURPOSE: A touch input structure for detecting the location and intensity of pressing force, a touch input device using the same and a method for detecting the location and intensity of pressing force are provided to accurately detect the location and intensity of pressing force without a force sensor. CONSTITUTION: External pressing force by a pointing object is applied to an upper layer(110). A lower layer(130) is separated from the upper layer at a predetermined interval. Supporting units(120) are included between the upper layer and the lower layer. The supporting units connect the upper layer with the lower layer. Interval detectors(140) detect interval changes between the upper layer and the lower layer.
