Abstract
A portable electronic device comprises at least one force sensor configured to generate a force signal based at least in part on a force applied to a touch-sensitive display and a processor configured to receive the force signal and to provide a feedback signal when the force exceeds a force threshold. The at least one force sensor may be integrated into the touch-sensitive display.
Claims23
An electronic device comprising:
- a touch-sensitive display including a layer, the layer comprising:
- a touch sensor disposed on a substrate;
- and
- a force sensor disposed on the substrate and configured to generate a force signal based at least in part on a force applied to the touch-sensitive display;
- and
- a processor configured to receive the force signal and provide a feedback signal when the force exceeds a force threshold,
- wherein the touch sensor comprises a plurality of touch sensor members and the force sensor is disposed in gaps between the touch sensor members.
A method comprising:
- detecting via a touch sensor a touch at a location on a touch-sensitive display, the touch sensitive display having a layer comprising the touch sensor disposed on a substrate and a force sensor disposed on the substrate, by utilizing the touch sensor, wherein the touch sensor comprises a plurality of touch sensor members and the force sensor is disposed in gaps between the touch sensor members;
- determining a force of the touch in response to a signal from the force sensor;
- and
- providing feedback to the touch-sensitive display when the force of the touch exceeds a force threshold.
A non-transitory computer readable medium having computer-readable code, which when executed by at least one processor of an electronic device, causes the electronic device to:
- detect via a touch sensor a touch at a location on a touch-sensitive display, the touch sensitive display having a layer comprising the touch sensor disposed on a substrate and a force sensor disposed on the substrate, by utilizing the touch sensor, wherein the touch sensor comprises a plurality of touch sensor members and the force sensor is disposed in gaps between the touch sensor members;
- determine a force of the touch in response to a signal from the force sensor;
- and
- provide feedback to the touch-sensitive display when the force of the touch exceeds a force threshold.
A touch-sensitive display comprising:
- a display;
- and
- a layer disposed on the touch-sensitive display, the layer comprising a touch sensor disposed on a substrate to detect a touch and determine a location of the touch on the touch-sensitive display, and a force sensor disposed on the substrate to generate a force feedback signal based on a force applied to the touch-sensitive display when the touch is detected,
- wherein the touch sensor comprises a plurality of touch sensor members and the force sensor is disposed in gaps between the touch sensor members.
