摘要：
A fingerprint sensor may include first and second electrodes, a light absorption layer isolated from direct contact with the first and second electrodes, and an insulation layer between the first electrode and the light absorption layer and further between the second electrode and the light absorption layer. A reflective layer may be between the light absorption layer and the first electrode. The insulation layer may include a first insulation layer between the first electrode and the light absorption layer, and a second insulation layer between the second electrode and the light absorption layer. A fingerprint sensor array including a plurality of fingerprint sensors may at least partially expose a plurality of sub-pixels of a display panel on which the fingerprint sensor array is located.
