摘要： Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder comprises an elongated shaft having an encoding pattern made up of axial markings and radial markings. The encoding pattern may be disposed around a circumference of the elongated shaft. The optical encoder also includes an optical sensor. In embodiments, the optical sensor includes an emitter and a photodiode array. The emitter causes light to shine on the encoding pattern. The encoding pattern reflects the light back to the photodiode array and the photodiode array determines movement of the shaft based on the reflected light.

摘要： A submersible electronic device such as a waterproof cellular telephone may be provided with an image sensor. The image sensor may capture images of underwater objects. Control circuitry in the submersible electronic device may adjust image contrast and color balance based on information from sensors and other information. The electronic device may have an ambient light sensor. The ambient light sensor may be a color ambient light sensor and may be used in measuring ambient lighting conditions above water and underwater. A depth sensor may be used in measuring the depth of the image sensor and other components of the electronic device underwater. Information on the depth of the image sensor, information on the distance of an underwater object to the image sensor, and angular orientation information for the electronic device and image sensor may be used in color balancing an image.

摘要： An electronic device is provided with a display and a display-integrated light sensor. The display includes a transparent cover layer, light-generating layers, and a touch-sensitive layer. The display-integrated light sensor is interposed between the transparent cover layer and a display layer such as the touch-sensitive layer or a thin-film transistor layer of the light-generating layers. The light-generating layers include a layer of organic light-emitting material. The display-integrated light sensor can be implemented as an ambient light sensor or a proximity sensor. The display-integrated light sensor may be a packaged light sensor that is integrated into the display layers of the display or may be formed from light-sensor components formed directly on a display circuitry layer such as the touch-sensitive layer or the thin-film transistor layer.

摘要： Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.
