Abstract: Certain aspects of the present disclosure generally relate to a touch panel. The touch panel may include a cover layer, of a plurality of layers, configured to receive a touch force applied to the touch panel. The touch panel may include a force determination set of layers, of the plurality of layers, to determine a magnitude of the touch force applied to the touch panel. The force determination set of layers may include a piezoelectric layer with a set of force determination pixels. The set of force determination pixels may be arranged in a matrix to address the set of force determination pixels. A force determination pixel may be configured to generate a charge for determining a location of the touch force applied to the touch panel and a magnitude of the touch force applied to the touch panel.
