摘要： The present disclosure relates to an optical device for a Near Eye Display (NED). The optical device comprising a waveguide, a first Optical Element (OE), a switchable second OE and a third OE. The first OE receives light and couples the light into the waveguide towards the switchable second OE. The switchable second OE comprising a plurality of independently switchable optical segments arranged one after the other along the waveguide. The switchable second OE receives the light from the first OE and redirects the light, with the switchable optical segments, into the waveguide towards the third OE. Moreover, the third OE couples the light received from the switchable second OE out of the optical device. The present disclosure also provides a NED device comprising an optical device and an image generator. The image generator emits light corresponding to an image to a waveguide of the optical device.

摘要： A display (100) for generating an image with a perceived depth (104) of image pixels differing from the actual depth (103) of the image pixels (300), the display comprising: an array of microlenses (101) having a first pitch along a first direction (X); a plurality of arrays of light sources (102) underneath the array of microlenses, an array of light sources having a second pitch along the first direction, the second pitch differing from the first pitch; and means for addressing the plurality of arrays of light sources. Each array of light sources corresponds to one perceived image pixel, and each light source in an array is present underneath a different microlens. The means for addressing the arrays of light sources is adapted for addressing each light source in one array of light sources in unison.

摘要： Embodiments of monolithic antenna architectures are described herein which comprise one or more antenna elements are formed in an integrated process with associated electronic components. One such architecture (400') comprises a thin film transistor layer (430) formed on a flexible substrate (410). A dielectric layer (450) is formed over the thin film transistor layer (430) with an electrode or antenna structure (460) formed over the dielectric layer (440). In this way, a chip in the thin film transistor layer is of comparable size to that of the antenna structure and can be formed as a monolithic structure.
