The viewing area of half or one third be biological characteristic cog region), and in the description of product of electronic equipment 10 inform to
Identify object.
In addition, the scheme of this first embodiment can also improve the Moire fringe defect of fingerprint image and steady noise lacks
It falls into.Specifically, referring to shown in Fig. 4, the production and assembling of light collecting layer 21 and display screen 12 be likely to occur deviation (it should be understood that this
Assembling deviation can control in a certain range), so that light collecting layer 21 and first is spaced 122 dislocation.At this point, the first interval of alignment originally
In 122 each micro through hole 211, there may be several micro through holes 211 to be no longer aligned with the first interval 122.But due to the first interval
122 cover at least two micro through holes 211, thus there are at least one micro through hole 211 be still aligned with the first interval 122 can
It can property.In actual products, the aperture of micro through hole 211 is spaced 122 size much smaller than first, even if between light collecting layer 21 and first
Every 122 dislocation, but 211 number of micro through hole being aligned with the first interval 122 can be very much, these are aligned micro- with the first interval 122
Through-hole 211 is aligned with the same photosensitive unit 22 again, and the photosensitive unit 22 is enable to incude the light that these micro through holes 211 are transmitted
Line.As a result, when misplacing the photosensitive unit 22 at corresponding first interval 122 also can normal induction light so that by processing
The fingerprint image obtained afterwards is clear and accurate, is not in Moire fringe and fixed picture noise.Conversely, if interval is only directed at one
Micro through hole 211, and this micro through hole 211 is directed at a photosensitive unit 22, when interval misplaces with micro through hole 211, is just unable to satisfy
The blur-free imaging condition of " pinhole imaging system ", cause photosensitive unit 22 can not normal induction light, the fingerprint obtained after treatment
Image just will appear Moire fringe and fixed picture noise.
To sum up, the scheme of this first embodiment can either realize life using 121st area of pixel (i.e. viewing area) of display screen 12
Object collection apparatus and identification, to biological characteristic identification function is integrated in the viewing area of electronic equipment 10.Compared to tradition
Electronic equipment 10, the scheme of this first embodiment can expand viewing area, and make non-display area relative decrease, to improve
The screen accounting of electronic equipment 10.Also, due to carrying out physical characteristics collecting under display screen 12, without being opened in display screen 12
Hole, therefore ensure that the structural strength of display screen 12 and the complete appearance of electronic equipment 10.In addition, the side of this first embodiment
Case, which can also improve, even is eliminated Moire fringe defect and steady noise defect.

Two intervals 123, the quantity at the second interval 123 are at least one.Second interval 123 can be aligned at least one micro through hole 211, and
The micro through hole 211 being aligned with the second interval 123 is directed at the same photosensitive unit 22.Second interval 123 is also used for through the reflection
Light is equally used for induction reflection photogenerated sensing signal with the second 123 corresponding photosensitive units 22 of interval.From the above mentioned, when
When two intervals 123 are only aligned with a micro through hole 211 (as shown in Figure 2 and Figure 3), if light collecting layer 21 and the second interval 123 occur
Dislocation, the biometric image at the second interval 123 will appear Moire fringe and fixed picture noise at this time, but second is spaced
123 still can be used for being imaged.It is formed by biometric image at first interval 122 still to be able to guarantee quality, therefore whole
The scheme of this first embodiment still improves Moire fringe defect and steady noise defect on body.When the second interval 123 and extremely
When few two micro through holes 211 are aligned (as shown in Figure 5), the second interval 123 is equal with the first interval 122 at this time, the second interval 123
Cover at least two micro through holes 211 with the first interval 122.As a result, when light collecting layer 21 and display screen 12 misplace, the first interval
Moire fringe defect and steady noise defect can be eliminated by 122 and being formed by fingerprint image at the second interval 123.
In this first embodiment, further, any one interval between the pixel 121 of display screen 12 is at least two
Micro through hole 211 is aligned, and is directed at the same photosensitive unit 22 with whole micro through holes 211 of the same spaced-apart alignment.I.e. at this time
All interval is the first interval 122, and the whole viewing areas of display screen 12 can be used as living things feature recognition area.Thus not only
Optimization even has been eliminated Moire fringe problem and steady noise problem, moreover it is possible to realize full frame living things feature recognition.
As shown in Figure 2 and Figure 4, in this first embodiment, photosensitive unit 22 has photosurface (i.e. for receiving light
Face).Preferably, the orthographic projection being spaced on photosurface corresponding with photosensitive unit 22 is fallen within photosurface.Photosensitive list as a result,
Member 22 has bigger photosensitive area, can be realized the biometric image acquisition of bigger field range.It is of course also possible to unlimited
In this, as long as photosensitive unit 22 can sense the light across interval transmission to sensitive surface.
In this first embodiment, further, the distance of light collecting layer 21 to display screen 12 is adjustable.Its inherent mechanism
