Pressure sensing display

Abstract

A device includes an electronic display supported in a display chassis, a digitizer sensor overlaid on the electronic display, a circuit configured to detected touch interaction with the digitizer sensor based on output sampled and a display controller configured to control output on the electronic display. The electronic display includes an electrostatic discharge (ESD) shield layer. The ESD shield layer is electrically connected to device ground and the impedance to the device ground of the ESD shield layer is configured to be sensitive to pressure applied on the digitizer sensor during user interaction. The digitizer sensor output is sensitive to the change in the impedance of ESD shield layer to the device ground.
