Description
Technical field
The utility model is related to touch screen technology field, especially a kind of 3D cover plates for integrating full frame fingerprint recognition.
Background technology
With the development of science and technology, the glass cover-plate in current touch screen is developed so far from original 2D, 2.5D and derives both sides
Many curved surface 3D glass cover-plates such as curved surface, four side curved surfaces.The many bend glass cover plates of 3D can not be with because being limited to back side bending on-plane surface
Former 2D, 2.5D back side plane equally carry out using ink printing carry out decorative appearance processing, and because many bend glass cover plates of 3D because
Edge is curved design therefore impact resistance difference is easily broken and burst, and fragment, which splashes easily to hurt sb.'s feelings, causes personal safety.
Current mobile phone safe mode is from pattern unblock, password unblock, face unblock, in numerous personal security's unlocking manners
After appearance, the higher unlocked by fingerprint of safety coefficient is also occurred in that.Fingerprint, because it has unchangeable property, uniqueness and conveniently
Property, almost turn into the synonym of living things feature recognition.Fingerprint refers to the convex recessed uneven generation of the positive surface skin of the finger tips of people
Streakline.The different line type of the regular arrangement form of streakline.Starting point, terminal, binding site and the bifurcation of streakline, referred to as fingerprint
Details.
Point formed by interruption, bifurcated in fingerprint or turnover is exactly details, and these details, can be with
Say the confirmation that just there is provided fingerprint uniqueness.Wherein it is typically destination node and bifurcation and ramification point, isolated point, ring
Point, short grain etc..By recording fingerprint ridge orientation, characteristic point position (determining position by X/Y axles) etc., with regard to one can be set up
Unique Fingerprint Lock in the world, and key is exactly fingerprint.
Due to each orientation for carrying out finger scan not exclusively, impetus difference also brings along different degrees of change
Shape, can so have largely fuzzy fingerprint again, so the key of fingerprint identification technology is correctly to extract feature and realize correct
Matching.Fingerprint recognition is related to numerous subjects such as image procossing, pattern-recognition, computer vision.Fingerprint is recognized, is exactly first first
Fingerprint base is set up, original fingerprint data turns into initial identification code.
In terms of current intelligent touch mobile phone/flat board, push type capacitance type fingerprint is sensed in existing market touch-control mobile phone/flat board
Device is all individually individual chip element, but be due to that sensor surface is to be easily damaged to cause service life to drop using silicon materials
It is low, therefore strengthened glass/sapphire glass can be all installed on fingerprint sensor protected and improve sensor service life.
From the point of view of current smart mobile phone, Ge Jia manufacturers fingerprint recognition mainly has positive Home strong, the three kinds of mounting means in the back side and side.
It is well known that fingerprint recognition module is arranged on the use habit that front more meets people, it is also more convenient to operate, still
Overall design difficulty will be increased, it is necessary to which the factor for considering and taking into account also can be more, and the requirement of outward appearance is also higher；And fingerprint recognition mould
Group, which is installed, to be overleaf easiest to realize, cost is also minimum, and the relatively positive scheme of appearance requirement is relatively low, therefore by part hand
Machine/flat board manufacturer is used, but the operating experience of user is poorer than positive scheme.As for side press-key, side scheme due to
Technical performance is poor, and Consumer's Experience is also bad, and design difficulty is not also small, therefore can't turn into main flow.Side fingerprint recognition is all
The scheme for being intended only as differentiation is present.
Further from the point of view of smart mobile phone development, back side fingerprint recognition is encased wireless with compatibility in adaptation mobile phone/flat board
Also there are more difficulties in terms of charging scheme.It can be seen that front identifying schemes and back side identifying schemes compare tool market sky
Between, and elapse over time, front identifying schemes will obtain maximum due to its good Consumer's Experience sense in smart mobile phone field
Market accounting, as fingerprint recognition mainstream scheme.Moreover, the application development from fingerprint recognition on smart mobile phone can also
Find out that front identifying schemes trend is increasingly obvious.
