Problems solved by technology

[0002] At present, many mobile phones on the market have added fingerprint recognition function. The fingerprint recognition function can provide functions such as fingerprint unlocking and fingerprint encryption. However, due to the thickness of the screen module, the sensor cannot collect enough useful signals, and the capacitive fingerprint recognition sensor cannot Recognize fingerprints pressed on the screen across the screen
[0003] In related technologies, infrared light fingerprint recognition sensors and ultrasonic fingerprint recognition sensors are used to identify fingerprint lines on the screen, which have strong enough penetration performance, but it means higher power consumption and larger module volume
At present, companies such as OFILM, which provide ultrasonic fingerprint recognition module packaging for Qualcomm, have not been able to reduce the size to a small enough size, and the recognition accuracy and speed also need to be greatly improved.

Abstract

The invention discloses a display screen, an array substrate thereof, a fingerprint identification method, and an electronic device. The array substrate includes: a plurality of pixel units, wherein each pixel unit includes a drive module, a light-emitting device, at least one ultrasonic receiver, and a control panel. Module, the drive module is used to provide driving current to the light-emitting device to drive the light-emitting device to light up; the ultrasonic receiver is used to receive ultrasonic signals; the control module controls the ultrasonic receiver to turn on when the light-emitting device is turned on; the ultrasonic transmitter, the ultrasonic transmitter emits ultrasound. Thus, full-screen fingerprint recognition can be realized, and by integrating the control module of the ultrasonic receiver into the driving circuit of the light-emitting device, the complexity and scale of the circuit can be reduced, and the size of the module can also be reduced. In addition, each Each pixel unit has an ultrasonic receiver, which can greatly improve the accuracy of recognition.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display screen, an array substrate thereof, a fingerprint identification method, and electronic equipment. Background technique [0002] At present, many mobile phones on the market have added fingerprint recognition function. The fingerprint recognition function can provide functions such as fingerprint unlocking and fingerprint encryption. However, due to the thickness of the screen module, the sensor cannot collect enough useful signals, and the capacitive fingerprint recognition sensor cannot Recognize the fingerprint pressed on the screen across the screen. [0003] In the related art, the infrared fingerprint recognition sensor and the ultrasonic fingerprint recognition sensor are used to recognize the fingerprint pattern on the screen, which has a strong enough penetrating performance, but it means higher power consumption and larger module volume. At pre...
