Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Since a possibility that leading to hooking, there are many kinds, for example, glue hardening deforming, contraction distortion, internal stress deformation
Deng, it is difficult to determine specific Deformation Reasons.Applicant has found after a large amount of attempt, when screen, glue frame and fingerprint sensor group
At space, i.e., when space is not sealing space in glue frame, can effectively solve the problem that the problem of mark occurs in screen.This method is
What can prevent the reasons why deformation from cannot still determine completely, and a kind of possible reason is that the glue frame shielded in lower fingerprint acquisition device is set
It is equipped with opening, so logical with glue frame outer space gas phase in glue frame, no pressure is poor inside and outside glue frame, will not be due to even if screen is softer
Pressure difference generates deformation；If the space in glue frame be it is closed, that is during heating and cooling, the sky in space in glue frame
Gas expanded by heating and contraction, glue frame inner and outer air pressure will be uneven, to pressure difference occur, lead to hooking.
It is the Structure explosion diagram of fingerprint acquisition device under a kind of screen provided in an embodiment of the present invention, which can referring to Fig. 3
To include screen 1, fingerprint sensor 2 and glue frame 3 for fingerprint sensor 2 to be fixed on to 1 side of screen.Screen 1, fingerprint
The space that sensor 2 and glue frame 3 form is not sealing space.
The screen 1 can be flexible screen.Flexible screen 1 can be realized the display for shielding lower fingerprint recognition for any one
Screen, such as OLED display screen.
Space to realize that flexible screen 1, fingerprint sensor 2 and glue frame 3 form is not sealing space, can be in glue frame 3
At least one connects the opening 4 in space and the glue frame external space in glue frame for upper setting, and can also be arranged on fingerprint sensor 2 will not
Influence the opening of its function.As shown in figure 3, space is the space at glue frame inner region A in glue frame.The boundary of glue frame inner region A
It can be made of the frame of glue frame and the line at the both ends that are open.The line at opening both ends is not the line of necessary being, and
It is for virtual line.
Wherein, glue frame 3 is not in contact with the induction region of fingerprint sensor 2.For example, glue frame 3 can surround fingerprint sensing
The induction region of device 2 is laid with, to prevent glue frame 3 from blocking fingerprint sensor 2, influences the acquisition of fingerprint.It needs to illustrate
It is that the glue frame 3 can be integrated design, or non-integral design.When glue frame 3 is integrated design, glue frame 3 can be square
Shape may be other shapes, such as round.When glue frame 3 is non-integral design, glue frame 3 can be by segment not interconnected
Composition, such as be made of two parallel or not parallel frames, or be made of multiple glue points.It should be noted that of the invention
Embodiment does not carry out concrete restriction to the shape of glue frame 3.
In embodiments of the present invention, opening 4 can be opened for clean cut system opening, labyrinth type opening, punched-type opening, depressed
One of mouth is a variety of.
As shown in figure 3, opening 4 can be open for clean cut system, clean cut system is open, and the frame of glue frame 3 is truncated.Opening 4 can be with
Including one or more, when including multiple openings, each opening can be located on any one frame.The two of clean cut system opening
End can be located on a line frame of glue frame, can also be as shown in figure 4, the both ends of clean cut system opening are located at two of glue frame
On frame, that is to say, that the glue frame of sealing lacks a line frame, also forms clean cut system opening in this way.
As shown in figure 5, opening 4 can be open for labyrinth type.To realize labyrinth type opening, close in glue frame 3 can open
Setting one or more is for forming the interior frame 31 in 4 channels of opening at the position of peripheral frame where mouth end.The present invention
The quantity to interior frame 31 and length do not carry out concrete restriction to embodiment.The design of labyrinth type opening increases the channel of opening 4
It is long, the air circulation in glue frame and outside glue frame not only may be implemented, but also since open channel is to environmental contaminants such as steam, dusts
Absorption can largely prevent environmental contaminants from entering in glue frame 3, to prevent environmental contaminants from polluting fingerprint sensor
Induction region, and then prevent environmental contaminants from influencing accurate acquisition of the fingerprint sensor to fingerprint.
As shown in fig. 6, opening 4 can be open for punched-type.Punched-type opening can pass through any a line of glue frame 3
The channel of frame, punched-type opening is parallel to the tiling plane of glue frame 3.
As shown in fig. 7, opening 4 can be open for depressed.Any a line in glue frame 3 can be set in depressed opening
On frame, depressed opening recess direction perpendicular to glue frame 3 tiling plane.Fig. 6 and Fig. 7 is that opening is provided in glue frame
The side view of side.
It should be noted that various types of openings can be set multiple in glue frame 3, the embodiment of the present invention is not to above-mentioned each
Quantity, position and the size of the opening of seed type carry out concrete restriction.
The thickness of the glue frame 3 can be 10um-200um, it is preferable that can be set to 40um.The thickness direction of glue frame 3
Perpendicular to the tiling plane of glue frame 3.
The material that glue frame 3 uses may include one of pressure sensitive adhesive, silica gel or foam rubber.
In the concrete realization, it can be set multiple fingerprint sensors 2 in flexible screen 1, and be laid with and multiple refer to for pasting
The glue frame 3 of line sensor 2, the embodiment of the present invention do not limit the quantity for the fingerprint sensor 2 being arranged in flexible screen 1 specifically
System.
It is the flow chart of the production method of fingerprint acquisition device under a kind of screen provided in an embodiment of the present invention referring to Fig. 8, it should
Method may comprise steps of.
Step 81, glue frame is set in the side of flexible screen or in the side of fingerprint sensor, has in the glue frame setting
At least one connects the opening in space and the glue frame external space in the glue frame.
Step 82, the fingerprint sensor is fixed on to the side of the flexible screen by the glue frame.
In the concrete realization, glue frame can be laid on flexible screen side by way of smearing, then again by fingerprint sensing
Device is pasted onto glue frame, so that fingerprint sensor to be pasted onto the side of flexible screen, and then acquires flexibility by fingerprint sensor
Fingerprint image on screen.Glue frame can also be arranged on fingerprint sensor, then fingerprint sensor is pasted onto flexible screen.
Fingerprint sensor can be pasted onto the side of flexible screen OLED luminescent layer backlight.
The embodiment of the invention also provides a kind of fingerprint sensor, the fingerprint sensor is fixed on flexible screen by glue frame
Side, be provided at least one opening for connecting space and the glue frame external space in the glue frame in the glue frame.
