DISPLAY PANEL PROTECTION WITH OVERPRESSURE SENSOR ON MOBILE DEVICE

摘要

An overpressure sensing mechanism protecting display panels on mobile computing devices from inadvertent external overpressures. The sensing mechanism comprises a pressure sensor coupled to a display panel and operable to trigger a warning alarm to a user upon detection of an overpressure exerted on the touchscreen. The user receiving the warning alarm may withdraw the overpressure promptly and prevent the display panel from being damaged.

主权项

1. A mobile computing device comprising:
a display panel; a bus; a processor coupled to said bus; and a memory coupled to said processor; a pressure sensor coupled to said display panel and configured to:
detect an external pressure applied to said display panel; andgenerate a pressure signal representative of said external pressure; control logic coupled to said pressure sensor and configured to:
compare said pressure signal with a predetermined value; andgenerate an overpressure signal if said pressure signal is greater than said predetermined value; and an Input/Output (I/O) device coupled to said control logic and configured to generate an indicia indicative of a presence of said external pressure responsive to said overpressure signal.
