Abstract

The invention provides an electronic device. The electronic device comprises a base plate, a display die set and a fingerprint recognizing die set, wherein the display die set and the fingerprint recognizing die set are arranged on the base plate; the fingerprint recognizing die set comprises a touch layer, a signal sending layer, a signal receiving layer and a first thin-film transistor array which are sequentially overlapped and arranged; the signal sending layer is used for continuously sending an ultrasonic signal to the contact layer and the signal receiving layer; the touch layer is used for reflecting the ultrasonic signal according to the sensed fingerprint; the signal receiving layer is used for receiving the ultrasonic signal and converting the received ultrasonic signal into an electric signal to transmit to the first thin-film transistor array; the first thin-film transistor array is used for acquiring a fingerprint gray level image according to the electric signal from the receiving layer; the display die set comprises a second thin-film transistor array which drives the display die set to display the image; the first thin-film transistor array and the second thin-film transistor array are formed on the base plate together.

Description

technical field [0001] The invention relates to an electronic device. Background technique [0002] Currently, electronic devices such as smartphones and tablet computers use fingerprint sensors to enhance data security. For example, the electronic device may use a fingerprint as an unlock password to protect private data stored in the electronic device. However, the fingerprint sensor in the existing electronic device is usually installed separately from other components in the electronic device, which leads to complex fabrication and low integration of the electronic device. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device. [0004] The electronic device includes a substrate, a display module and a fingerprint identification module arranged on the substrate. The fingerprint identification module includes a contact layer, a signal sending layer, a signal receiving layer and a first thin film transistor array which are ...
