Embodiment Construction
[0042] It can be seen from the background art that the fingerprint imaging module in the prior art has the problem that it is often difficult to balance the imaging quality and the integration degree of the module. The reason is analyzed in combination with the structure of the existing fingerprint imaging module.
[0043] refer tofigure 1 , shows a schematic cross-sectional structure of a fingerprint imaging module.
[0044] like figure 1 As shown, the fingerprint imaging module is an ultra-thin optical fingerprint imaging module. The fingerprint imaging module realizes fingerprint imaging through the principle of photoelectric conversion, including: a light source, an optical area sensor 12 located on the light source, and a sensing surface 13 located on the optical area sensor 12 .
[0045] When collecting fingerprints, the finger is pressed on the sensing surface 13; the incident light produced by the light source is projected onto the sensing surface 13, and reflection ...
