Abstract
The disclosure relates to a displacement sensing touch panel and a touch screen using the touch panel. The touch panel includes a first panel, a second panel, and a displacement sensor sandwiched between the first panel and the second panel. The displacement sensor deforms when a pressure is applied to the first panel. The touch screen includes the touch panel, a controller where the touch positions and forces applied are deduced from the readings of the displacement sensor, and a display coupled to the controller and adjacent to the touch panel. Displacement information is collected through the displacement sensor to deduce the positions and magnitudes of the forces applied to the first panel of the touch panel or touch screen.
