20160131903 | PREVENTING DISPLAY LEAKAGE IN SEE-THROUGH DISPLAYS - Examples are disclosed herein that relate to reducing image leakage in a see-through display system. One disclosed example provides a see-through display system including a narrowband light source configured to emit light within a first spectral band, a polarized image producing stage configured to polarize the light emitted by the narrowband light source and to produce a polarized image, and a see-through optical system configured to receive the polarized image from the polarized image producing stage and to transfer the polarized image to a display output. The see-through optical system further includes a narrowband polarizer positioned to receive light from the narrowband light source and the polarized image producing stage, the narrowband polarizer being configured to polarize light within a second spectral band that is at least partially overlapping with the first spectral band. | 05-12-2016 |
20160161742 | HEAD-UP DISPLAY DEVICE - A head-up display device for a vehicle includes a housing, a temperature detector, and a light source control unit. The head-up display device projects, toward an external projection member, lights indicating display information for displaying an image produced by the reflected lights to a user positioned at a predetermined position. The housing houses the display portion and the light source disposed facing each other via heat transfer space. The temperature detector is disposed in a surrounding area of the display portion and the light source, and detects a temperature of the surrounding area. The light source control unit increases brightness of the emitted lights by increasing driving current of the light source when the detected temperature is lower than a reference low-temperature. The heat generated by the increased driving current is transferred to the display portion via the heat transfer space, and increases a temperature of the display portion. | 06-09-2016 |

20220137404 | METHODS AND SYSTEMS FOR GENERATING VIRTUAL CONTENT DISPLAY WITH A VIRTUAL OR AUGMENTED REALITY APPARATUS - Several unique configurations for interferometric recording of volumetric phase diffractive elements with relatively high angle diffraction for use in waveguides are disclosed. Separate layer EPE and OPE structures produced by various methods may be integrated in side-by-side or overlaid constructs, and multiple such EPE and OPE structures may be combined or multiplexed to exhibit EPE/OPE functionality in a single, spatially-coincident layer. Multiplexed structures reduce the total number of layers of materials within a stack of eyepiece optics, each of which may be responsible for displaying a given focal depth range of a volumetric image. Volumetric phase type diffractive elements are used to offer properties including spectral bandwidth selectivity that may enable registered multi-color diffracted fields, angular multiplexing capability to facilitate tiling and field-of-view expansion without crosstalk, and all-optical, relatively simple prototyping compared to other diffractive element forms, enabling rapid design iteration. | 05-05-2022 |
