Receiving device

A receiving device includes an optical detector, a first detection region, and a second detection region. The optical detector detects a position of an object of interest to be detected by receiving, with use of one or more of light-receiving portions, reflected light that occurs when light emitted from one or more of light-emitting portions is reflected by the object of interest to be detected. The first detection region is provided at a position closer to the optical detector, and is for detecting movement of the object of interest to be detected with the use of the optical detector. The second detection region is provided at a position farther from the optical detector than the first detection region, and is for detecting presence of the object of interest to be detected with the use of the optical detector.

Eraser for touch displays

An optical IR touch sensing apparatus configured to determine, based on output signals of light detectors, a light energy value for each light path across a touch surface, and generate a transmission value for each light path based on the light energy value. A processor is then configured to process the transmission values to determine an object reference point on the touch surface where the light is attenuated or occluded by an object and determine, from a set of light paths unaffected by an object, a set of object boundary light paths comprising one or more light paths passing closest to the object reference point. The characteristics of the object may then be determined in dependence on the set of object boundary light paths.

Electronic device display for through-display imaging
11073712 · 2021-07-27 · ·

Systems and methods for through-display imaging. A display includes an imaging aperture defined through an opaque backing. An optical imaging array is aligned with the aperture. Above the aperture, the display is arranged and/or configured for increased optical transmittance. For example, a region of the display above, or adjacent to, the imaging aperture can be formed with a lower pixel density than other regions of the display, thereby increasing inter-pixel distance (e.g., pitch) and increasing an area through which light can traverse the display to reach the optical imaging array.
