Abstract
Wearable display devices providing wireless communication are described. According to one aspect of the present invention, a wearable display device is made in form of a pair of glasses and includes an antenna layer and a transceiver. The antenna layer may be disposed on top of one or both of integrated lenses in the glasses to allow wireless communication between the device and other devices (e.g., controller or hotspot). Each of the lenses has a designated display area based on a light waveguide and allows a wearer to enjoy seamless XR or other immersive experience.
Claims19
A wearable display device comprises:
- an eyeglasses frame;
- at least one integrated lens including a light waveguide, wherein the integrated lens is framed in the eyeglasses frame;
- at least one temple attached to the eyeglasses frame;
- an enclosure integrated on one side of the temple, the enclosure including an image engine generating optical images to be projected into one side of the integrated lens;
- an antenna layer, including a plurality of antenna elements disposed on one side of the integrated lens and an Indium tin oxide (ITO) layer disposed on an opposite side of the integrated lens, wherein part of the integrated lens sandwiched between the antenna elements and the ITO layer determines capacitance of the antenna layer, wherein dimensions of each of the antenna elements are tuned in accordance with the capacitance to ensure that, when all antenna elements are coupled together, the antenna elements collectively achieve a desired resonant frequency, data is received wirelessly in the enclosure via the antenna layer for the image engine to generate the optical images;
- and
- a transceiver facilitating wireless communication via the antenna layer, wherein the transceiver includes a photo mixer for generating or detecting terahertz (THz) radiation, and one or more optical sources generating two optical beams directed onto a photoconductive material to generate a terahertz output signal for the THz radiation when applying a voltage bias across the photoconductive material.
