Abstract
An electronic system and method detect orientations of display devices of an electronic system, and determine an orientation mode of the display devices. The system and method identify one or more software applications presenting information on at least one of the display devices. Electronically controlled privacy filters in the display devices are individually activated or deactivated in the at least one of the display devices to alter opacity of the displayed information based on one or more of the orientations of the display devices and/or the one or more software applications.
Claims20
An electronic system comprising:
- multiple electronic display devices each including an individually and electronically controllable privacy filter that adjusts opacities of information that is electronically presented on the display device;
- one or more sensors operably coupled with the display devices, the one or more sensors configured to detect orientations of the display devices;
- and
- a control unit configured to receive a signal from the one or more sensors that indicates the orientations of the display devices that are detected, the control unit configured to identify an orientation mode of the display devices, the control unit configured to activate or deactivate the electronically controllable privacy filters in the display devices to independently polarize and diffract light generated by the display devices at different angles to modify the information presented on the display devices based on the orientation mode.
A method comprising:
- detecting orientations of multiple display devices;
- identifying an orientation mode of the display devices based on the orientations that are detected;
- and
- individually activating or deactivating electronically controllable privacy filters in the display devices to independently polarize and diffract light generated by the display devices at different angles to modify information presented on the display devices based on the orientation mode that is identified.
An electronic system comprising:
- display devices each having an electronically controllable privacy filter;
- at least one sensor configured to detect orientations of the display devices;
- and
- a control unit configured to determine an orientation mode of the display devices and to identify one or more software applications presenting information on at least one of the display devices, the control unit configured to individually activate or deactivate the electronically controlled privacy filter in the at least one of the display devices to polarize and diffract light generated by the electronic display devices at different angles to modify the information presented on the at least one of the display devices, the control unit configured to individually activate or deactivate the electronically controlled privacy filter based on one or more of the orientations of the display devices or the one or more software applications.
