摘要： A system and method includes a display device comprising a spatial light modulator arranged to output spatially modulated light to form an image. The system further includes a waveguide pupil expander configured to receive spatially modulated light from the display device at an input port thereof and to expand the viewing window of the system. The system further comprises a controller. In examples, the controller is configured to control the spatially modulated light output by the display device, such as to control (e.g., turn off) a light source of the display device, in response to a signal indicating detection of the breakage of glass. The signal indicating detection of the breakage of glass may be generated in response to the detection of stray laser light of the holographic system by an eye-tracking system.

摘要： A display device, a photomask for a display device and a method for fabricating a display device comprising the photomask is described. The display device comprises a plurality of pixels arranged to spatially modulate light having a first characteristic. The display device further comprises a pixel mask structure. The pixel mask structure comprises a diffractive pattern that is configured to diffract light having the first characteristic and to transmit light having a second characteristic (without diffraction). The diffractive pattern of the pixel mask structure substantially surrounds the plurality of pixels.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for adjusting depth of AR content on HUD. A viewing device identifies, based on sensor data, a physical object visible through a transparent display of the vehicle. The sensor data indicates an initial distance of the physical object from the vehicle. The viewing device gathers virtual content corresponding to the physical object and generates an initial presentation of the virtual content based on the initial distance. The viewing device presents the initial presentation of the virtual content on the transparent display at a position on the transparent display corresponding to the physical object. The viewing device determines, based on updated sensor data, an updated distance of the physical object and generates an updated presentation of the virtual content based on the updated distance. The viewing device presents the updated presentation of the virtual content on the transparent display of the vehicle.

摘要： An image processing engine and method of forming a hologram of a target image for projection using data streaming. An input or primary image is sub-sampled using a kernel and the secondary image output used to generate a hologram of the target image. A technique of kernel sub-sampling using a plurality of two or more data streams provides improvements in efficiency, including reduced data storage requirements and increased processing speed.

摘要： There is provided a head-up display having an eye-box comprising a driver monitoring system, picture generating unit and optical system. The driver monitoring system is arranged to illuminate and monitor a driver. The driver monitoring system comprises a first display channel. The picture generating unit is arranged to display a picture on a replay plane. The picture generating unit comprises a second display channel Each display channel comprises a light source, spatial light modulator and controller. Each light source is arranged to emit light. Each spatial light modulator is arranged to receive light from the respective light source and output spatially-modulated light in accordance with a computer-generated hologram displayed on the spatial light modulator to form a respective light pattern on the replay plane. Each controller is arranged to output the computer-generated hologram to the spatial light modulator. The optical system is arranged to relay each light pattern from the replay plane. The optical system comprises an input, output and at least one mirror. The input is arranged to receive light of each light pattern. The output is arranged to output light of each light pattern. The at least one mirror is arranged to guide light from the input to the output along an optical path. The light pattern formed by the first display channel is an infrared light pattern. Each light pattern is a holographic reconstruction.

摘要： There is provided a head-up display for a vehicle. The head-up display has a first housing and a second housing. The first housing comprises a picture generating unit and optical system. The second housing comprises a substantially flat cover glass and a layer. The picture generating unit is arranged to output pictures. The picture generating unit comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulate the light in accordance with computer-generated light-modulation patterns displayed on the spatial light modulator to form a holographic reconstruction corresponding to each picture. The optical system is arranged to receive the pictures output by the picture generating unit and relay the pictures using an optical combiner to form a virtual image of each picture. The optical combiner combines light output by the picture generating unit with light from a real-world scene to present combined images to a viewer within an eye-box. The second housing is disposed between the first housing and optical combiner. The substantially flat cover glass is arranged to protect the first housing. The layer is arranged to change the trajectory of light such that any sunlight reflected by the cover glass is deflected away from the eye-box.
