Abstract:
1. A method of operating an electronic device, comprising: providing an electronic device comprising a first panel and a second panel, wherein the first and second panel are hingedly connected and rotatable relative to each other about an axis in an opening rotational direction and a closing rotational direction, which is opposite to the opening rotational direction; applying a rotational force to one of the first and second panels to rotate the first panel relative to the second panel in the opening rotational direction beyond a first predetermined angle, at which point the first panel spontaneously rotates in the opening rotational direction relative to the second panel in the absence of an external rotational force applied to the electronic device in the opening rotational direction; allowing the first panel to continue to spontaneously rotate relative to the second panel in the opening rotational direction until the relative rotation of the first panel stops at about a second predetermined angle; applying a rotational force to one of the first and second panels to rotate the first panel relative to the second panel in the opening rotational direction up to an arbitrary angle between the second predetermined angle and a third predetermined angle, at which point the first panel is substantially still relative to the second panel in the absence of an external force applied to the electronic device; and wherein each of the first, second and third predetermined angles is an angle formed between the first and second panels.
