A fingerprint identification system for a mobile phone and an identification method. The system includes a fingerprint collection module, a spectral chip, a data storage module and an identification module. The fingerprint collection module is arranged under a mobile phone screen. The mobile phone screen provides a light source to illuminate a fingerprint. The spectral chip is configured to modulate an incident spectrum, and convert an optical signal into an electrical signal to be amplified and converted into a digital signal or code for output. A finger reflection spectral data and a fingerprint image data are collected by inversion of an optical signal intensity information and a pixel location information. The data storage module is configured to store reflection spectral data and fingerprint image data of a real finger input in advance. The identification module is configured to compare the collected data with the pre-stored data.

The first electrode and gate electrode of each of the photo transistors is electrically connected with a common electrode or a gate line for display driving. Thus, it is possible to operate photo sensors to perform photo sensing even without all or some of the signal lines necessary for the operation of the photo sensors, thereby increasing the aperture ratio and transmittance.

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.

Example systems, devices, media, and methods are described for presenting an interactive game in augmented reality on the display of a smart eyewear device. A hand tracking utility detects and tracks the location of hand gestures in real time, based on high-definition video data. The detected hand gestures are compared to library of hand gestures and landmarks. Examples include synchronized, multi-player games in which each device detects and shares hand gestures with other devices for evaluation and scoring. A single-player example includes gesture-shaped icons presented on a virtual scroll that appears to move toward an apparent collision with corresponding key images, awarding points if the player's hand is located near the apparent collision and the detected hand shape matches the moving icon.
