With reference to reference to figure 2, the structure for amplifying signal of the inner structure of square frame 140 in display device embodiment shown in Fig. 1 is shown
Figure.
The display structure sheaf 110 includes substrate 111 and multiple pixel cells 112, and the multiple pixel cell 112 is in institute
Show and be arranged in array on substrate 111.
The substrate 111 is used to provide technological operation surface, and provides mechanical support for the pixel cell 112.Specifically
, the substrate 111 is transparent substrates, and the material of the substrate 111 is glass.
The pixel cell 112 is used to produce the display light 110a to realize that image is shown.The display light 110a is certainly
Backwards to the direction outgoing of shown substrate 111, so as to display image.
As shown in Fig. 2 the multiple pixel cell 112 is arranged in array, there is sky at least between adjacent pixel unit 112
Gap 114.
The space 114 is used to make light be transmissive to the display structure sheaf 110, so as to improve the display structure sheaf
110 light transmittance.Specifically, it is filled with light transmissive material, such as silica, silicon nitride or optical cement, UV in the space 114
Glue etc..
It should be noted that in the present embodiment, the diode displaying structure is the pole of active matrix organic light-emitting two
Pipe shows structure, therefore the pixel cell 111 includes Organic Light Emitting Diode and switching device, so the pixel cell
111 and light tight, the space 114 only between adjacent pixel unit 111 can realize the transmission of light.But the utility model
In other embodiment, according to the pixel cell structure, the difference of design, it is printing opacity that the pixel cell, which can have part,
Therefore light can also transmit the display structure sheaf from partial pixel unit.
With continued reference to Fig. 1, the protective layer 120 is on the display structure sheaf 110, for protecting the display structure
Layer 110 and other hardware.Protective layer 120 described in display light transmission caused by the display structure sheaf 110 realizes that image shows
Show.
The protective layer 120 at least partially fibre faceplate 122.Fibre faceplate 122 (Fiber Optics Plates,
FOP) it is regularly arranged by a large amount of optical fiber and is formed, therefore with numerical aperture is big, interstage coupling loss is small, high resolution, light
The features such as learning zero thickness, can transmit HD image without distortions.So the setting of the fibre faceplate 122 has no effect on institute
Protective layer 120 described in stating display light transmission, that is, the display effect of the display structure sheaf 110 is not interfered with.

In addition, in the sensing face 121, the projected area of space 114 and the projected area of pixel cell 112
The ratio between should not it is too big also should not be too small.
In the sensing face 121, the projected area of space 114 and the projected area of pixel cell 112 such as
Fruit is too small, then may influence the light transmittance of the display structure sheaf 110, particularly be likely to result in reflection light transmission mistake
It is low, it is unfavorable for the collection of fingerprint image, is unfavorable for improving the quality for obtaining fingerprint image.Specifically, in the present embodiment, in institute
State in sensing face 121, the ratio between the projected area of space 114 and the projected area of pixel cell 112 are less than or equal to 1:10,
The space accounting of the i.e. described projected area of space 114 and the projected area of pixel cell 112 is more than or equal to 5%.
Because the fibre faceplate 122 has the function that collimation to transmitted ray, therefore when the display light 110a projections
When on to the sensing face 121, the part display light 110a transmitted through the fibre faceplate 122 has higher collimation
Property, so as to form the preferable reflected light 110b of collimation；And the reflected light 110b also needs to transmit the fibre faceplate
122, the fibre faceplate 122 can also collimate to the reflected light 110b, so transmiting the mistake of the fibre faceplate 122
Cheng Zhong, the scattering process suffered by the display light 110a and reflected light 110b is weaker, and the veiling glare formed is less, institute

Divide the protective layer 120 to be arranged to the way of fibre faceplate 122, the use of fibre faceplate 122 can either be reduced, reduce material supplier
Skill cost, additionally it is possible to the position of fingerprint collecting is indicated by the viewing area, so as to be advantageous to the electronic device user
The lifting of experience.
It should be noted that the thickness of the protective layer 120 should not it is too big also should not be too small.
If the thickness of the protective layer 120 is too small, it is unfavorable for the defencive function of the protective layer 120, may shadow
Ring the stability and service life of the display device.Specifically, in the present embodiment, the thickness of the protective layer 120 be more than or
Equal to 0.2mm.
In addition, in the present embodiment, the way that the part protective layer 120 is arranged into fibre faceplate 122 is only example.This
In utility model other embodiment, the protective layer can also be fibre faceplate, i.e., the whole protective layer is fibre faceplate.
This way can effectively improve the protecting effect of the protective layer 120.
