Abstract
A head-mountable electronic device includes an optical module frame, a display coupled to the optical module frame and extending in a display plane, and an eye-tracking assembly. The eye-tracking assembly includes a flat electrical cable, for example a flexible printed circuit (FPC), coupled to the optical module frame and disposed about a perimeter of the display, and a light emitting diode (LED) electrically coupled to the flat electrical cable and configured to direct light away from the display. The flat electrical cable defines a major plane oriented generally orthogonal to the display.
Claims20
A head-mountable electronic device, comprising:
- an optical module frame;
- a display coupled to the optical module frame and extending in a display plane;
- a circuit board disposed about a perimeter of the display, a major plane of the circuit board being orthogonal to the display plane;
- and
- a side-firing light emitting diode (LED) mounted to the circuit board along the major plane on a surface facing away from the display.
An optical module for a wearable electronic device, comprising:
- an optical module frame;
- a display coupled to the optical module frame and extending in a display plane;
- a bezel coupled to the optical module frame;
- a seal disposed between the bezel and the optical module frame;
- a substrate mounted to the bezel and positioned radially outward from a perimeter of the display, the substrate defining a major plane oriented non-parallel to the display plane;
- and
- a light emitting diode (LED) electrically coupled to a non display-facing surface of the substrate.
An assembly for a head-mountable display device, comprising:
- a substrate defining a major plane and coupled to a display assembly of the head-mountable display device, the display assembly including a display coupled to a frame;
- and
- a light emitting diode (LED) array, each LED of the LED array being mounted to the major plane of the substrate and oriented to project light parallel to the major plane.
