摘要： A fingerprint identification detection circuit, a touch screen and a display device is disclosed. The fingerprint identification detection circuit can include a photosensitive diode, a first switch transistor, a second switch transistor and a voltage follower transistor, wherein the first switch transistor can include a metal oxide transistor, and the second switch transistor and the voltage follower transistor both can include a low-temperature polycrystalline silicon transistor. There is little current leaking from the first switch transistor by using the metal oxide transistor as the first switch transistor. Even in the case of low light intensity, photocurrent can be detected, which may thereby improve the detection precision of the fingerprint identification detection circuit.
