Piezoelectric Actuator And Method |
| 摘要 |
An apparatus including a display; and at least one piezoelectric member connected to the display. The at least one piezoelectric member is configured to move the display. When the display is pressed to mechanically stress the at least one piezoelectric member, the apparatus is configured to wake up the apparatus from a sleep mode based upon electricity from the at least one piezoelectric member, and/or determine a location where the display was pressed based upon respective signals from at least two of the piezoelectric members. |

1. An apparatus comprising:
a display; and at least one piezoelectric member connected to the display, where the at least one piezoelectric member is configured to move at least a portion of the display, where, when the display is pressed to mechanically stress the at least one piezoelectric member, the apparatus is configured to:
wake up the apparatus from a sleep mode based upon electricity from the at least one piezoelectric member, and/ordetermine a location where the display was pressed based upon respective signals from at least two of the piezoelectric members, and/ordetermine a force and/or impulse applied from a voltage measured from the at least one piezoelectric member. |
