Patent number: 10901679Abstract: Examples of mirroring a screen between two devices include establishing a communication link by a sink device with a source device to mirror a screen of the source device on the sink device. Upon determining a same orientation of the source device for a specific time period, a display OFF command is sent to the source device. The display OFF command is indicative of turning OFF a backlight of the screen of the source device. Further, an event notification may be received by the sink device upon occurrence of an event at the source device. The event includes an incoming communication or a change in the orientation of the source device. In addition, in response to the event notification, a switch command is sent to the source device to pause the signal stream and to turn ON the backlight of the screen of the source device.Type: GrantFiled: February 6, 2017Date of Patent: January 26, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Isaac Lagnado, Yi-Kang Hsieh, Chung-Chun Chen, Han-Kuang Chang
