Sensing the screen positions in a dual screen phone

A method comprising:

• generating an electromagnetic field by a processor of a device, wherein the device comprises:
• first and second screens comprising first and second display panels, respectively, wherein the first and second display panels are configured to receive input and provide a graphical output;
• a hinge connected to the first and second screens;
• and
• a first magnet proximal to the first screen and a second magnet proximal to the second screen, the first and second magnets configured to resist opening of the device when the hinge is in a closed position in which the first and second screens are oriented substantially back-to-back in adjacent planes;
• sensing, by a first Hall-Effect sensor positioned on the first screen, a first strength of the electromagnetic field generated by the processor;
• sensing, by a second Hall-Effect sensor on the second screen, a second strength of the electromagnetic field generated by the processor;
• determining, by the processor, the hinge is in an open position based on both of the first strength of the electromagnetic field generated by the processor sensed by the first Hall-Effect sensor and the second strength of the electromagnetic field generated by the processor sensed by the second Hall-Effect sensor;
• in response to determining the hinge is in the open position, displaying, by the processor, information across the first and second screens;
• determining, by the processor, the hinge is in the closed position based on both of the first strength of the electromagnetic field generated by the processor sensed by the first Hall-Effect sensor and the second strength of the electromagnetic field generated by the processor sensed by the second Hall-Effect sensor;
• and
• in response to determining the hinge is in the closed position, displaying, by the processor, a mirror image on the first screen and the second screen.

A non-transitory computer-readable medium comprising processor-executable instructions which, when executed by a processor of a device, causes the processor to:

• generate an electromagnetic field;
• sense, by a first Hall-Effect sensor, a first strength of the electromagnetic field generated by the processor;
• sense, by a second Hall-Effect sensor, a second strength of the electromagnetic field generated by the processor;
• determine the hinge is in an open position based on both of the first strength of the electromagnetic field generated by the processor sensed by the first Hall-Effect sensor and the second strength of the electromagnetic field generated by the processor sensed by the second Hall-Effect sensor;
• in response to determining the hinge is in the open position, display information across the first and second screens;
• determine the hinge is in a closed position in which the first and second screens are oriented substantially back-to-back in adjacent planes based on both of the first strength of the electromagnetic field generated by the processor sensed by the first Hall-Effect sensor and the second strength of the electromagnetic field generated by the processor sensed by the second Hall-Effect sensor;
• and
• in response to determining the hinge is in the closed position, display a mirror image on the first screen and the second screen, wherein:
• the device comprises:
• first and second screens, the first and second screens comprising first and second display panels, respectively, the first and second display panels configured to receive input and provide a graphical output;
• a hinge connected to the first and second screens;
• a first magnet proximal to the first screen;
• and
• a second magnet proximal to the second screen, wherein:
• the first and second magnets configured to resist opening of the device when the hinge is in the closed position;
• the first Hall-Effect sensor is positioned on the first screen, and
• the second Hall-Effect sensor is positioned on the second screen.
