Electronic device capable of rotating display image and display image rotating method thereof

A method for rotating a display image of an electronic device, the electronic device comprising a control module, a gravity sensor, an angle sensor, a display and a base pivotally connected to the display and having an orientation, the display being adapted to display the display image, the method comprising:

• determining whether an absolute rotation angle of the display relative to a gravity axis detected by the gravity sensor is equal to or greater than a predetermined absolute angle threshold, wherein when the absolute rotation angle is equal to or greater than the predetermined absolute angle threshold, a first rotating signal is generated;
• determining whether a relative rotation angle of the display relative to the base detected by the angle sensor is equal to or greater than a first relative angle threshold and is equal to or less than a second relative angle threshold, wherein when the relative rotation angle is equal to or greater than the first relative angle threshold and is equal to or less than the second relative angle threshold, a second rotating signal is generated, wherein the second relative angle threshold is larger than the first relative threshold;
• and
• determining to control whether the display image is rotated by the control module according to a relative relationship between the first rotating signal and the second rotating signal received by the control module;
• wherein when the control module receives the first rotating signal and the second rotating signal at the same time, the control module controls the display image not to rotate.

An electronic device, capable of rotating a display image, comprising:

• a base;
• a display having a top end and a bottom end that are opposite to each other;
• a pivotal assembly comprising at least one rotating axle, the bottom end of the display being pivotally connected to the base via the pivotal assembly;
• an angle sensor mounted at the at least one rotating axle, for detecting a relative rotation angle of the display relative to the base;
• a gravity sensor mounted at the display, for detecting an absolute rotation angle of the display relative to a gravity axis;
• and
• a control module adapted to control a rotating state of a display image of the display according to a relative relationship between the absolute rotation angle and the relative rotation angle;
• wherein when the absolute rotation angle detected by the gravity sensor is equal to or greater than a predetermined absolute angle threshold, a first rotating signal is generated, and the control module receives the first rotating signal to control the display image to rotate;
• wherein the relative rotation angle detected by the angle sensor is equal to or greater than a first relative angle threshold and is equal to or less than a second relative angle threshold, a second rotating signal is generated, and the control module receives the second rotating signal to rotate the display image, and the second relative angle threshold is larger than the first relative angle threshold;
• wherein when the control module receives the first rotating signal and the second rotating signal at the same time, the control module controls the display image not to rotate.
