In addition, in description of the present utility model, unless otherwise indicated, " multiple " are meant that two or more.
If occurring the term of " process " in this specification, it refers not only to independent process, when can not clearly be distinguished with other processes,
As long as can realize that the effect desired by the process is then also included within this term.In addition, the number represented in this specification with "~"
Value scope refers to the scope that the numerical value recorded before and after "~" is included as minimum value and maximum.In the accompanying drawings,
Structure is similar or identical to be indicated by the same numeral.
Refer to Fig. 1.Fig. 1 is the touching display screen structural representation of the first embodiment of the utility model.Touch-control shows
Display screen 100 mainly includes contact panel 10, fingerprint collecting layer 20 and backlight module 30.The fingerprint collecting layer 20 is touched between described
Control between panel 10 and the backlight module 30.Specifically, the contact panel 10 includes upper substrate 11, liquid crystal layer 12 and lower base
Plate 13.The liquid crystal layer 12 is located between upper substrate 11 and infrabasal plate 13.The infrabasal plate 13 and fingerprint collecting layer 20
It is disposed proximate to.Projection of the contact panel 10 on fingerprint collecting layer 20 is contained in the fingerprint collecting layer 20.So
The purpose of setting is so that whole contact panel 100 can be carried out fingerprint collecting.The light source that the backlight module 30 is sent
Fingerprint collecting layer 20 can be passed through, and for the light source needed for fingerprint collecting layer 20 is provided, the fingerprint collecting layer 20
The region collection fingerprint under the light transmission state of contact panel 10 can be passed through..
Specifically, during fingerprint collecting is carried out, when finger is positioned over the upper substrate 11, utilizing multipoint-touch-technology
Determine the region 110 (dotted line part in Fig. 1) of contact panel described in finger touch, the control circuit control of contact panel 10
(unnumbered) the generation electric deflection of liquid crystal molecule in liquid crystal layer 12 corresponding with the region 110 of the finger touch, so that
The region 110 of finger touch is in light transmission state.Now, the light source that backlight module 30 is sent enters touch-control after fingerprint collecting layer 20
The region 110 of the finger touch in light transmission state of panel 10, and the finger touch in light transmission state through contact panel 10
Region 110 after reach finger at, and after total reflection return fingerprint collecting layer 20, complete fingerprint gatherer process;It can manage
Solution, during whole fingerprint collecting, removes the corresponding liquid crystal molecule in region 110 of above-mentioned finger touch on contact panel 10
Outside generation electric deflection, the liquid crystal molecule in other regions is non deflected, and other regions of contact panel 10 are in impermeable light state.Cause
This, extraneous light (i.e. noise) can not enter liquid crystal panel 10 via other regions, and then avoid ambient interference and refer to
The gatherer process of line, reduces the collection difficulty of fingerprint.
In a kind of possible implementation of the utility model, multiple through holes 21, institute are provided with the fingerprint collecting layer 20
State the light that backlight module 30 sends and enter the contact panel 10 through the through hole 21, so that needed for providing fingerprint collecting process

Separated between 111 by black matrix 112.It is understood that the color blocking 111 includes red resistance, green resistance and blueness resistance.Institute
Multiple through holes 21 are stated to correspond with the multiple color blocking 111.In other embodiment of the present utility model, the fingerprint
Acquisition layer 20 can be light transmissive material, so as to omit the through hole 21.
In a kind of possible implementation of the utility model, the backlight module 30 can include white light source 31, infrared ray
Light source 32 and light guide plate 33.For the backlight module 30 of side entering type, white light source 31 and infrared light sources 32 are all disposed within described lead
The side of tabula rasa 33.It is understood that the white light source 31 is used to provide light source, the infrared ray for the contact panel
Source 32 is used to provide light source for fingerprint collecting layer.Specifically, when contact panel 10 is used for display image, the infrared ray
Light source 32 is closed, and the white light source 31 is opened, and then backlight module 30 is the light source needed for contact panel 10 provides display;When tactile
When control panel 10 needs to carry out fingerprint collecting, the infrared light sources 32 are opened, and the white light source 31 is closed, in case white light is to referring to
The formation interference of line gatherer process, the infrared light sources 32 is the light sources needed for fingerprint collecting layer 20 provides fingerprint collecting.
It is understood that the infrared light sources 32 used during fingerprint collecting are only exemplary citings, fingerprint collecting layer 20
