PIEZORESISTIVE FORCE SENSOR INTEGRATED IN A DISPLAY
First Claim
1. A device, comprising:
- a substrate;
an input device provided on a first portion of the substrate; and
at least one piezoresistive sensor to sense a force applied to the input device, where the piezoresistive sensor is provided on a second portion of the substrate, where the second portion is different than the first portion.

Abstract
A device may include a substrate including an input device on a substrate and at least one piezoresistive sensor formed on the substrate outside the area of the input device. A device may include a display formed on a substrate, at least one piezoresistive sensor formed on the substrate, and a processor to calculate an applied force and activate a force response based on the calculated applied force. A method may include monitoring resistance associated with one or more piezoresistive sensors to detect changes in a force applied to a display device, detecting a change in resistance associated with the one or more piezoresistive sensors, calculate a force applied to the display device based on the detected change in resistance, activating a force response in proportion to the change in resistance detected, and displaying a result of the force response via the display device.
