Patent ID: 8599570

Claim:
An electronic device comprising: a front frame; a back cover fixed to the front frame; a display panel fixed between the front frame and the back cover; a circuit board fixed between the front frame and the back cover, the circuit board comprising a first contact and a plurality of second contacts surrounding the first contact; and a support stand mounted to the back cover, the support stand being rotatable relative to the back cover and secured in different orientations so as to support the display panel oriented in respective different orientations, the support stand comprising a central shaft electrically connected to the first contact, a third contact fixed to the central shaft, and a supporting leg coupled to the central shaft, the third contact being jointly rotatable with the central shaft so as to be connectable to each of the second contacts when the support stand is secured in the corresponding orientations; wherein the circuit board comprises a circuit and a processor, the circuit is configured to generate different signals when the first contact is connected to different second contacts, and the processor is configured to adjust an orientation of display content on the display panel based on the signal generated by the circuit.
