Abstract
A portable electronic device includes a display body, a rotatable component, and an optical communication module. The display body has a display screen. The rotatable component is pivotally connected to the display body. The rotatable component has an opening. The optical communication module is disposed inside the rotatable component. The optical communication module includes a light emitter and a light receiver, and the light emitter and the light receiver faces the opening.
Claims19
A method for optical communication with a portable electronic device, comprising:
- rotating a rotatable component relative to a display body to orient an optical communication module toward a target direction;
- transmitting, from a light emitter of the optical communication module, an optical signal through an opening;
- and
- receiving, at a light receiver of the optical communication module, an external optical signal via the opening,
- wherein the rotating enables the optical communication module to communicate over multiple incident angles while maintaining communication quality.
A method for stabilizing optical link performance in a portable electronic device, comprising:
- rotating a rotatable component about an axis while maintaining a center line connecting a light emitter and a light receiver of an optical communication module substantially parallel to the axis;
- and
- synchronously rotating the light emitter and the light receiver by a same angle so that an emitting distance and a receiving distance remain substantially consistent,
- thereby maintaining substantially consistent transmit and receive power during operation.
A method for stabilizing optical link performance in a portable electronic device, comprising:
- directing an optical signal between an optical communication module and an external environment through an opening that tapers inward to form an inclined wall;
- and
- filtering incident light at the opening with a light-permeable member to pass a target wavelength band,
- wherein the inclined wall functions as a light mask to concentrate incident light to the optical communication module and expand an effective communication angle.
