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.

Abstract: A touch display substrate and a touch detection method thereof. The touch display substrate includes: a base substrate, and a photo-sensitive touch element and an Organic Light-Emitting Diode (“OLED”) device that are arranged on the base substrate sequentially. The photo-sensitive touch element includes a touch electrode layer, a photo-sensitive material layer, an insulating layer and an ITO layer that are arranged sequentially, wherein an orthographic projection of a touch sensing area of the touch electrode layer completely covers an orthographic projection of a pattern of the photo-sensitive material layer, and is within an orthographic projection of the ITO layer. The arrangement of the photo-sensitive touch element neither changes the sequence of manufacturing the layers of the display substrate, nor affects the illumination of the touch display substrate and is suitable for manufacturing a large-size touch screen.
