Claim Text:
1. An electronic device comprising: a display region configured to display images; a peripheral region around the display region; a fingerprint inputting region defined at the peripheral region; a display assembly corresponding to the display region for displaying images; an identify assembly corresponding to the fingerprint inputting region configured to obtain a grayscale image of the object pressed against the electronic device; and a substrate, wherein the display assembly and the identify assembly are located on the substrate; the identify assembly comprises a first thin film transistor (TFT) array; the display assembly comprises a second TFT array; the first TFT array and the second TFT array are integrated to form a TFT substrate; and the TFT substrate is arranged on the substrate; and wherein the identify assembly further comprises a contact layer, a signal transmitter layer, a signal conduction layer, and a signal receiving layer which are orderly arranged on the first TFT array; the signal transmitter layer continuously generates ultrasonic signals to the contact layer and the signal receiving layer; the contact layer reflects ultrasonic signals; the signal conduction layer superposes the reflected ultrasonic signal from the contacting layer and the ultrasonic signal from the signal emitting layer; the signal receiving layer transfers the superposed ultrasonic signals into electronic signals; the first TFT array obtains the grayscale image of the object pressed against the electronic device based on the transferred electronic device generated by the signal receiving layer.
