Abstract: An electronic device such as a head-mounted device may have a display that produces a display image. The head-mounted device may have an optical system that merges real-world images from real-world objects with display images. The optical system provides the real-world images and display images to an eye box for viewing by a user. The optical system may use time interleaving techniques and/or polarization effects to merge real-world and display images. Switchable devices such as polarization switches and tunable lenses may be controlled in synchronization with frames of display images. Geometrical phase lenses may be used that exhibit different lens powers to different polarizations of light.

Abstract: To extract light from a light-emitting diode (and thereby improve efficiency of the display), a microlens stack may be formed over the light-emitting diode. The microlens stack may include an array of microlenses that is covered by an additional single microlens. Having stacked microlenses in this way increases lens power without increasing the thickness of the display. The array of microlenses may be formed from an inorganic material whereas the additional single microlens may be formed from an organic material. The additional single microlens may conform to the upper surfaces of the array of microlenses. An additional low-index layer may be interposed between the light-emitting diode and the array of microlenses. A diffusive layer may be formed around the light-emitting diode to capture light emitted from the light-emitting diode sidewalls.

Abstract: A display may include an optical film to promote sunglass-friendly viewing of the display. Displays may include linear polarizers. For example, a liquid crystal display may have a linear polarizer above a liquid crystal layer, whereas an organic light-emitting diode display may have a linear polarizer that forms a portion of a circular polarizer to reduce reflections in the display. Displays that emit linearly polarized light may not be compatible with polarized sunglasses. To ensure an optimal user experience for users wearing sunglasses, displays may include sunglass-friendly optical films. A sunglass-friendly optical film may be a film formed from a birefringent material such as a polymer or liquid crystal. The sunglass-friendly optical film may have an optical axis that is at a 45° angle relative to the optical axis of the underlying linear polarizer. The sunglass-friendly optical film may be patterned to have reduced thickness regions.

Abstract: An electronic device may have a display such as a liquid crystal display. A color filter layer may be formed on a display layer such as a transparent substrate layer. The color filter layer may include an array of color filter elements on a central portion of a surface of the transparent substrate layer. The color filter layer may include a peripheral color filter of a single color that at least partially surrounds the color filter elements on the central portion of the inner surface. In an inactive portion of the display, an opaque masking material may be formed over the peripheral color filter. In an active portion of the display the opaque masking material may form a grid that covers interfaces between adjacent color filter elements. The peripheral color filter may completely cover the surface of the substrate in the entire inactive portion of the display.

Abstract: Electronic equipment with displays may be provided. A first display may be mounted in a first housing and a second display may be mounted in a second housing that is adjacent to the first housing. The first housing may rotate relative to the second housing about a hinge axis. The first housing may be a lid and the second housing may be a base housing that is coupled to the lid by a hinge. A first display may be mounted in the first housing and a second display may be mounted in the second housing. Polarizer layers and other optical layers in the displays may be configured to provide a viewer with the ability to view images on the displays while wearing vertically polarized sunglasses and to suppress reflections of light emitted by the first display off of the second display.

Abstract: A display may be provided with a color filter layer. The display may have a thin-film transistor layer and a layer of liquid crystal material that is interposed between the color filter layer and the thin-film transistor layer. The color filter layer may include an array of color filter elements on a transparent substrate. The color filter elements may be formed from colored photoresist. An inorganic layer may be deposited on the color filter elements. An opaque matrix such a black matrix formed from black photoresist may be formed on the inorganic layer. The color photoresist color filter elements may be rectangular and may be arranged on the transparent substrate in a rectangular array. The black matrix may contain an array of rectangular openings. Each of the openings of the black matrix may be aligned with a corresponding one of the color filter elements.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a locally modified region that overlaps the optical sensor. The locally modified region of the display may have a modification relative to a normal region of the display that does not overlap the optical sensor. The modification may mitigate diffractive artifacts that would otherwise impact the optical sensor that senses light passing through the display. To mitigate diffraction artifacts, the locally modified region of the display may use spatial randomization (e.g., spatial randomization of signal paths and/or spatial randomization of via locations), opaque structures may be formed with circular footprints, a black masking layer may be formed with circular openings, apodization may be used, and/or a phase randomization film may be included.

Abstract: An electronic device may have a display that provides image light to a waveguide. First and second liquid crystal lenses may be mounted to opposing surfaces of the waveguide. An coupler may couple the image light out of the waveguide through the first lens. The second lens may convey world light to the first lens. Control circuitry may control the first lens to apply a first optical power to the image light and the world light and may control the second lens to apply a second optical power to the world light that cancels out the first optical power. Each lens may include two layers of liquid crystal molecules having antiparallel pretilt angles. The pretilt angles and rubbing directions of the first lens may be antiparallel to corresponding pretilt angles and rubbing directions of the second lens about the waveguide.

Abstract: Display structures and methods of manufacture of display structure including a display panel with a curved three-dimensional film contour are described. In an embodiment, a display panel includes display area with a main body area and a plurality of petals extending from the main body area. The petals are folded into a curved three-dimensional (3D) film contour, and are separated by corresponding trenches between petals. The trenches may be filled with various seam hiding materials to visually obscure the trenches.
