Abstract
A virtual reality (VR) headset, system, and method of fabrication are disclosed. The VR headset includes a frame, a transparent display that includes an array of light-emitting diodes (LEDs), and a darkening layer having a controllable opacity, and a processor controlling the display and darkening layer. A proximity sensor detects a potential collision, and the opacity is changed from opaque to transparent in response to detection of the potential collision. The opacity is changed in response to activation of a virtual user input or predetermined eye movement.
Claims25
A virtual reality (VR) headset comprising:
- a frame configured to receive a head of a user;
- a substantially transparent display that includes a sparse array of micro light-emitting diodes (microLEDs) configured to display a VR image;
- and
- a darkening layer having a controllable opacity, the darkening layer disposed between a front of the frame and the substantially transparent display.
A layer stack comprising:
- a substantially transparent display that includes an array of micro light-emitting diodes (microLEDs) configured to provide a virtual reality (VR) image;
- and
- a darkening layer adjacent to the substantially transparent display and having a controllable opacity.
A virtual reality (VR) system comprising:
- a frame configured to receive a head of a user;
- a substantially transparent display that includes an array of individually-controllable micro light-emitting diodes (microLEDs) configured to provide VR images;
- a darkening layer having a controllable opacity, the darkening layer disposed between a front of the frame and the substantially transparent display;
- a processor configured to control the opacity of the darkening layer between an opaque mode in which external light is substantially blocked from passing therethrough and the VR images are provided by the substantially transparent display and a substantially transparent mode in which external light is substantially transmitted therethrough and the VR images are not provided by the substantially transparent display;
- and
- a battery configured to provide power to the display, the darkening layer, and the processor.
