    Abstract: A device for identifying a pattern over a first surface includes a photosensitive layer, and a light-guiding layer disposed between the photosensitive layer and the first surface. The photosensitive layer includes a plurality of photosensitive elements, each configured to convert incident light into an electrical signal. The light-guiding layer includes a plurality of light-guiding units, each positionally corresponding to one of the plurality of photosensitive elements. Each light-guiding unit include a plurality of light-transmitting portions, each configured to guide a light beam reflected from a feature of the pattern positionally corresponding thereto to transmit therethrough and reach one of the plurality of photosensitive elements corresponding to the each of the plurality of light-guiding units. The device can be used for identification of fingerprint, as well as other biometric or non-biometric features, and has a reduced thickness and an improved accuracy for pattern identification.

    Abstract: The present disclosure provides an ultrasonic fingerprint sensor, a display substrate, a driving method thereof and a display device. The ultrasonic fingerprint sensor includes: a base substrate; a driving structure provided on the base substrate and configured to transmit an ultrasonic signal; a receiving structure provided on the base substrate and configured to receive the ultrasonic signal reflected by a finger, and convert the ultrasonic signal into an electrical signal for determining fingerprint information, the driving structure and the receiving structure are provided in a same plane. Since the driving structure and the receiving structure of the ultrasonic fingerprint sensor of the present disclosure are in a same plane, the driving structure can be closer to the touch body (for example, a finger), which is advantageous for the ultrasonic waves generated by the driving structure to reach the finger to improve the touch accuracy.
