A fingerprint sensing module includes a first substrate, an active device, a photosensitive element layer, a collimation structure layer, a second substrate, a plurality of micro lenses, and a spacer pattern. The active device is disposed on the first substrate. The photosensitive element layer is disposed on the first substrate and is electrically connected to the active device. The collimation structure layer is disposed on the photosensitive element layer. The second substrate is disposed on the collimation structure layer. The micro lenses are disposed on a surface of the collimation structure layer facing away from the photosensitive element layer, and overlap the photosensitive element layer. The micro lenses are divided into a plurality of microlens groups, and the microlens groups are respectively located in a plurality of sensing pixel areas of the fingerprint sensing module. The spacer pattern extends between the microlens groups.

The first sensing element layer is disposed on the first substrate and includes multiple first sensing elements. The second sensing element layer is disposed on the first sensing element layer and includes multiple second sensing elements, wherein an orthographic projection of the second sensing element on the first substrate overlaps with an orthographic projection of the first sensing element on the first substrate.

Dual sensing device

A biological feature identification device includes a display device and a sensing device. The display device includes multiple pixels arranged along a first direction. The pixels each has a sub-pixel having a display element and a switch element. The sensing device includes multiple sensing units arranged along a second direction. The sensing units each has a sensing element. When the spatial frequency relation is |4*(RE/100)&#x2212;(1/SU)|&#x3e;A, the first and second directions are the same, and the biological feature identification device satisfy the criteria: A&#x3c;|4*(RE/100)&#x2212;(1/SU)|&#x3c;B. When the spatial frequency relation is |4*(RE/100)&#x2212;(1/SU)|&#x2264;A, the first and second directions form an angle, and the biological feature identification device satisfy the criteria: A&#x3c;|4*(RE/100)&#x2212;{1/[SU*Cos(&#x3b1;)]}|&#x3c;C. RE is the resolution of the display device, SU is the sensing unit size, &#x3b1; is the angle, 0&#xb0;&#x3c;&#x3b1;&#x3c;90&#xb0;, B and C&#x3e;A, and A is not equal to zero.
