Abstract

Particular embodiments described herein provide for an electronic device, that includes a display and a bounce reduction mechanism configured to provide an active counterforce to a force on the display. In an example, a proximity sensor can detect when a device is going to create the force on the display. In another example, a screen bounce detection engine to detect oscillations of the display and the bounce reduction mechanism is configured to provide an active counterforce to dampen oscillation of the display.

First claim

What is claimed is:

1. An electronic device, comprising:
a display, wherein the display includes a plurality of display regions;
a proximity sensor, wherein the proximity sensor can detect motion of an input device that is going to create a force on the display and one or more of the plurality of display regions where the input device will create the force on the display;
a plurality of screen bounce detection engines, wherein each of the plurality of display regions includes a screen bounce detection engine, wherein at least one screen bounce detection engine can determine a velocity of the input device; and
a bounce reduction mechanism, wherein when the determined velocity of the input device is greater than a threshold, the bounce reduction mechanism is configured to provide one or more active counter forces in response to the force on the display at an approximate time the input device contacts the display.

2. The electronic device of claim 1 , wherein the bounce reduction mechanism is configured to provide an active counter force to dampen oscillation of the display.

3. The electronic device of claim 1 , the bounce reduction mechanism is configured as a hinge.

4. The electronic device of claim 1 , wherein the bounce reduction mechanism is an oscillating piezoceramic actuator.

5. A method, comprising:
detecting, by a proximity sensor, motion of an input device that will create a force on a display that includes a plurality of display regions, wherein each of the plurality of display regions includes a screen bounce detection engine;
detecting, using the proximity sensor, one or more of the plurality of display regions where the input device will create the force on the display;
determining a velocity of the input device; and
providing, by a bounce reduction mechanism when the determined velocity of the input device is greater than a threshold, one or more active counter forces to counter the force on the display at an approximate time the input device contacts the display.

6. The method of claim 5 , wherein the bounce reduction mechanism is configured to provide an active counter force to dampen oscillation of the display.

7. The method of claim 6 , wherein the bounce reduction mechanism is configured as a hinge.

8. The method of claim 6 , wherein the bounce reduction mechanism is an oscillating piezoceramic actuator.

9. An electronic device, comprising:
a touchscreen display, wherein the touchscreen display includes a plurality of display regions;
a proximity sensor, wherein the proximity sensor can detect when motion of an input device that is going to create a force on the touchscreen display and one or more of the plurality of display regions where the input device will create the force on the touchscreen display;
a plurality of screen bounce detection engines, wherein each of the plurality of display regions includes a screen bounce detection engine, wherein at least one screen bounce detection engine can determine a velocity of the input device;
a bounce reduction engine configured to calculate a counter force to the force on the touchscreen display when the determined velocity of the input device is greater than a threshold; and
a bounce reduction mechanism configured to provide the counter force to the force on the touchscreen display at an approximate time the input device contacts the touchscreen display.

10. The electronic device of claim 9 , wherein the bounce reduction mechanism is configured to provide an active counter force to dampen oscillation of the touchscreen display.

11. The electronic device of claim 9 , wherein the bounce reduction mechanism is configured as a hinge.

12. A system, comprising:
a proximity sensor for detecting motion of an input device that will create a force on a display that includes a plurality of display regions and for detecting one or more of the plurality of display regions where the input device will create the force on the display;
at least one screen bounce detection mechanism for determining a velocity of the input device, wherein each of the plurality of display regions includes a screen bounce detection engine;
and
a bounce reduction mechanism for providing one or more active counter forces when the determined velocity of the input device is greater than a threshold to counter the force on the display at an approximate time the input device contacts the display.

13. The system of claim 12 , wherein the bounce reduction mechanism is configured to provide the active counter forces to dampen oscillations of the display.

14. The system of claim 12 , wherein the bounce reduction mechanism for providing the active counter forces is configured as a hinge.
