An electronic device may have light-emitting devices. A light-emitting device may include light-emitting diodes, a display, or other components that emit visual output. One or more image transport layers may be included in the electronic device. An image transport layer may have an input surface that receives an image and an output surface to which the image transport layer transports the image for viewing by a user. The image transport layers may have areas with compound curvature and other shapes. Deformed image transport layer structures such as deformed fibers in a coherent fiber bundle may be configured to hide gaps in displays and other structures. Displays may include light detectors that serve as a two-dimensional touch sensor. The touch sensor may detect touch input on an output surface of an image transport layer. Image transport layer material may be incorporated into buttons, elongated housings, wearable devices, and other equipment.

Content is projected onto the surface of water such that it can be viewed from either above or below the surface. Using distortion mapping, depth sensing, and de-noising, the image can remain unaffected by ripples and allow the user to interact within the body of liquid and/or use it as input. Liquids of different density can be layered on the surface to create different refraction planes. Water currents and jets can be used to actively reduce ripples from user interaction, as well as actively adding or removing liquid from the container to counteract displacement or create effect.

A reference position setting method includes: a process of displaying at least three markers on an operation surface; a process of acquiring coordinate values of a sensor coordinate system; a process of transforming the acquired coordinate value into coordinate values of a temporary coordinate system; and a process of transforming the transformed coordinate values into coordinate values of a screen coordinate system. At least one of parallel movement and rotation is performed with respect to the sensor coordinate system to transform the sensor coordinate system into the temporary coordinate system. Movement of the temporary coordinate system in a direction parallel to a plane including a second X-axis and a second Y-axis, and enlargement or reduction of the temporary coordinate system are performed to transform the temporary coordinate system into the screen coordinate system.

An electronic device has pixels that form an active area of a display for displaying images for a user. A layer of black ink or other opaque material may be formed on an inner surface of a display cover layer in an inactive area of the display that does not overlap pixels. The housing may have sidewalls such as a rear housing wall that faces away from the display. Ambient light sensor windows may be formed from tapered holes or other holes. The tapered holes may be formed in the opaque material on the display cover layer, may be formed in a rear housing wall or other hosing structure, or may be formed in other portions of the electronic device. Non-tapered holes may also form windows. Tapered holes may have sidewalls with portions that run parallel to their longitudinal axes and portions that are angled relative to their longitudinal axes.

A texture recognition device and a display device are provided. The texture recognition device includes a backlight element, configured to provide first backlight; a light constraint element, configured to perform a light divergence angle constraint process on the first backlight to obtain second backlight with a divergence angle within a preset angle range, the second backlight being transmitted to a detection object; and a photosensitive element, configured to detect the second backlight reflected by a texture of the detection object to recognize a texture image of the texture of the detection object.

A vehicle interior component configured to present a user interface for a vehicle occupant with vehicle systems may comprise a housing, cover structure and user interface system to present the user interface at a cover surface. The user interface may comprise a light display to transmit light from a light source and/or an input device comprising a mechanical coupling to interface with a sensor arrangement. The user interface may comprise output from the light display and/or input by interaction with the input device at the cover surface. The component may comprise a module comprising the light display and the input device. The module may comprise an absorber. The light display may comprise a light guide and/or display panel. The light guide may comprise a projection and/or icon to transmit light through an aperture and/or recess of the cover structure.

An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

A display device that has an image capturing function is provided. An image capturing device or a display device with high definition is provided. The display device includes first to fourth switches, a first transistor, a capacitor, and a light-emitting/receiving element. The first switch is connected to a gate of the first transistor. The second switch is connected to one of a source and a drain of the first transistor. An anode of the light-emitting/receiving element is connected to the other of the source and the drain of the first transistor through the third switch. The fourth switch is connected to the other of the source and the drain of the first transistor. One electrode of the capacitor is connected to the gate of the first transistor, and the other electrode of the capacitor is connected to the other of the source and the drain of the first transistor. The light-emitting/receiving element emits light of a first color, receives light of a second color, and converts the light into an electric signal.

A digital video ramp assembly incorporates process-formed structural LED tiles with modular components that join in a system of scalable structural LED tiles forming a complete LED display structure with integrated LED embedded tiles with interlocking and inter-trans-positioning features sometimes requiring additional structural framing.

A method and apparatus for creating an adaptive mosaic pixel-wise virtual Bayer pattern. The method may include receiving a plurality of monochromatic images from an array of imaging elements, creating a reference ordered set at infinity from the plurality of monochromatic images, running a demosaicing process on the reference ordered set, and creating a color image from the demosaiced ordered set. One or more offset artifacts resulting from the demosaicing process may be computed at a distance other than infinity, the ordered set may be modified in accordance with the computed offsets.
