  • Patent number: 11367407
    Abstract: A display driver according to the present invention includes a control part and a fault detection circuit. The control part sequentially incorporates first fault detection data and second fault detection data into a video signal during non-display periods of the video signal. The fault detection circuit binarizes each of a first pixel driving voltage and a second pixel driving voltage with a predetermined threshold voltage to obtain a first signal and a second signal. The first pixel driving voltage is generated based on the first fault detection data. The second pixel driving voltage is generated based on the second fault detection data. The fault detection circuit determines whether the first signal and the second signal match and outputs a fault detection signal that indicates a presence of a fault when the first signal and the second signal match.

  • Patent number: 11353711
    Abstract: A wearable display apparatus has a headset for display from left-eye and right-eye near-eye catadioptric pupil-forming optical systems, each defining an exit pupil. Each optical system has an image generator to direct image-bearing light for a 2D image from an emissive surface. A curved reflective surface along the view axis is partially transmissive and defines a curved intermediate focal surface. A beam splitter reflects light toward the curved reflective surface. An image relay optically conjugates the formed image with a curved aerial image formed in air at the curved intermediate focal surface. The image relay has a prism having an input surface facing the emissive surface of the image generator, an output surface facing the curved intermediate focal surface, and a folding surface between input and output surfaces for folding the optical path for light generated by the image generator. An aperture stop for the relay is within the prism.

  • Patent number: 11347051
    Abstract: Systems and methods for synthesizing an image of the face by a head-mounted display (HMD), such as an augmented reality device, are disclosed. The HMD may be able to observe only a portion of the face with an inward-facing imaging system, e.g., the periocular region. The systems and methods described herein can generate a mapping of a conformation of the portion of the face that is not imaged based at least partly on a conformation of the portion of the face that is imaged. The HMD can receive an image of a portion of the face and use the mapping to determine a conformation of the portion of the face that is not observed. The HMD can combine the observed and unobserved portions to synthesize a full face image.

  • Patent number: 11340742
    Abstract: A multi-layer conductive coating is substantially transparent to visible light, contains at least one conductive layer comprising silver that is sandwiched between at least a pair of dielectric layers, and may be used as an electrode and/or conductive trace in a capacitive touch panel. The multi-layer conductive coating may contain a dielectric layer of or including zirconium oxide (e.g., ZrO2) and/or silicon nitride, and may be used in applications such as capacitive touch panels for controlling showers, appliances, vending machines, electronics, electronic devices, and/or the like. The coating may have increased resistivity, and thus reduced conductivity, compared to pure silver layers of certain coatings, in order to allow the silver-based coating to be more suitable for use as touch panel electrode(s).

The substrate and coupling-in element (55) are formed of substantially different optical materials and the ratio between the fields of view of the light waves coupled-out from the substrate into the viewers' eye and of the light waves coupled inside the substrate, is substantially bigger than the refractive index of the substrate.
