FINGERPRINT RECOGNITION DEVICE, DISPLAY SCREEN AND DISPLAY DEVICE

摘要

The present invention provides a fingerprint recognition device, a display screen and a display device, which belong to the field of display technology and can solve the problem of high cost for conventional fingerprint recognition devices The fingerprint recognition device of the present invention arranged at a light emitting side of a display panel includes a protection substrate, a glass base positioned under the protection substrate, a plurality of detecting electrodes formed on the glass base, capacitance being formed between the plurality of detecting electrodes and ridges or valleys of a fingerprint when touching occurs, and a control unit used to recognize the fingerprint based on the capacitance. The fingerprint recognition device of the present invention has a simple structure and a low cost.
