  • Patent number: 10866458
    Abstract: An electronic device may include display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit may include light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes may be tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers may be incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display may be coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit may have additional solder mask layers to improve robustness, may include encapsulation, and may have traces with a varying pitch.

  • Publication number: 20200388213
    Abstract: A flat-panel display device and method to unify response times for all possible grey level transitions in a flat-panel display or an augmented reality display. A pixel drive compensator receives a frame from a graphics processing unit and two-dimensional temperature for pixels at a display panel to compensate for temperature variation across the display panel.

  • Publication number: 20200388224
    Abstract: A flat-panel display device and method to unify response times for all possible grey level transitions in a flat-panel display or an augmented reality display. A pixel drive compensator compares the current frame from a graphics processing unit and feedback from a previous frame to compensate for grey-level changes at a pixel level.

  • Patent number: 10795234
    Abstract: A monolithic optical device for light manipulation and control at visible wavelengths includes a device layer deposited on an sacrificial layer deposited on a reflective substrate. The device layer comprises an elastic support structure and nanoscale optical antenna elements, arranged such that the nanoscale optical antenna elements are capable of moving vertically in response to application of an electrostatic potential between the device layer and the reflective substrate. The sacrificial layer joins the elastic support structure to the reflective substrate. The reflective substrate is reflective at optical wavelengths.

  • Patent number: 10126466
    Abstract: A multifunctional dielectric gradient metasurface optical device has a layer of nanoscale dielectric gradient metasurface optical antenna elements deposited on a substrate layer, arranged with spatially varying orientations, shapes, or sizes in the plane of the device such that the optical device has a spatially varying optical phase response capable of optical wavefront shaping. The spatially varying optical phase response is a spatial interleaving of multiple distinct phase profiles corresponding to multiple optical sub-elements, thereby providing multifunctional wavefront shaping in the single optical element.
