Force and Location Sensitive Display
First Claim
1. A force and touch sensitive component, comprising:
- a first transparent layer;
a second transparent layer;
first conductive traces abutted to a first surface of the first transparent layer;
second conductive traces abutted to a second surface of the second transparent layer; and
deformable members interposed between the first and second transparent members, wherein the first and second conductive traces are configured to generate a first signal indicative of a force applied to the first transparent layer and a second signal indicative of a location on the first transparent layer at which the force is applied.

Abstract
A unit to provide both force and location detection includes a first transparent substrate (having first and second sets of conductive traces oriented in a first direction), a second transparent substrate (having a third set of conductive traces oriented in a second direction) and a plurality of deformable members (e.g., rubber beads) arranged between the first and second transparent substrates. The first set of conductive traces, in combination with the conductive traces of the second transparent element, provide a capacitance signal representing where a user touches the display element. The second set of conductive traces, in combination with the conductive traces of the second transparent element, provide a capacitance signal representing the amount of force applied to the display element. When used with a display element (e.g., a LCD or CRT), an input-output unit capable of both location sensing and force sensing operations is provided.
