When other function, the above-mentioned electric signal generated by pressure can be first passed through and open fingerprint identification function, then pass through fingerprint identification region
71 obtain the finger print information of user, to avoid false triggering fingerprint identification function.
For the cover board 8 in touch-control display module provided by the present invention, further the cover board 8 can be carried out a variety of
Surface treatment, detailed content please refer to following inventive embodiments.
Referring to FIG. 3, a kind of structural representation for specific touch-control display module that Fig. 3 is provided by the embodiment of the present invention
Figure.
It is different from foregoing invention embodiment, the embodiment of the present invention is discussed in detail on the basis of foregoing invention embodiment
The concrete structure of touch-control display module cover plate 8.Remaining content is described in detail in foregoing invention embodiment, herein
No longer repeated.
Referring to Fig. 3, in embodiments of the present invention, a variety of tables can be carried out backwards to 1 one side surface of the backlight to cover board 8
Surface treatment.Specifically, the first surface treatment is that cover board 8 is fabricated to rough surface backwards to 1 one side surface of the backlight, i.e.,
1 one side surface of the backlight is provided with multiple grooves in cover board 8.Certainly, in embodiments of the present invention, the groove is logical
It is often to be formed by groove by carrying out fine irregularities processing backwards to 1 one side surface of the backlight to cover board 8, the groove is usual
It is very tiny, come if user is with the naked eye usually unable to observe, it can but be formed by groove by fine irregularities processing
So that cover board 8 becomes rough surface backwards to 1 one side surface of the backlight.When ambient is irradiated to rough surface
When cover board 8 is backwards to 1 one side surface of backlight, scattering can occur for ambient without mirror-reflection occurs, to avoid
The occurrence of dazzle.
Second of surface treatment is that 1 one side surface of the backlight is provided with antireflective film 81 in cover board 8.Antireflective film 81
Also referred to as antireflective coating, also known as anti-reflection film.Even elimination can be effectively reduced instead by being provided with the surface of the cover board 8 of antireflective film 81
Penetrate the generation of light, while cover board 8 physical property, such as mechanical property can be improved etc..
The third surface treatment is to be coated with anti-fingerprint oil coating 82 backwards to 1 one side surface of the backlight in cover board 8.It is anti-
Fingerprint oil is also referred to as anti-fingerprint oil, anti-fingerprint paint, has anti-fingerprint, the effect of oil rub resistance.Specific anti-fingerprint oil coating 82 can
To be divided into lipophilic, oil type is refused, related 82 specific type of anti-fingerprint oil coating is not specifically limited in embodiments of the present invention.
Certainly, above-mentioned anti-fingerprint oil coating 82 can be arranged on the surface of above-mentioned antireflective film 81.Above describe three kinds of tables
The specific method of surface treatment can only carry out cover board 8 backwards to 1 one side surface of the backlight in embodiments of the present invention
Any one surface treatment；Cover board 8 can also be carried out backwards to 1 one side surface of the backlight at arbitrary two kinds of surfaces simultaneously
Reason can also carry out three kinds of surface treatments backwards to 1 one side surface of the backlight to cover board 8 simultaneously, can also even carry out
Other kinds of surface treatment.Particular content in relation to being surface-treated to cover board 8 is not specifically limited in embodiments of the present invention.
Further, in embodiments of the present invention, the cover board 8 is tempered glass cover plate.
So-called tempered glass cover plate has the glass cover-plate of compression in surface programming.Compared to common cover board 8, steel
Changing glass cover-plate has higher structural strength, can bear more ambient pressures, to preferably protect entire touch-control aobvious
Show that module is not easily susceptible to damage.
A kind of touch-control display module that the embodiment of the present invention is provided, by cover board 8 backwards to 1 one side surface of backlight into
The a variety of surface treatments of row, can effectively promote the optical property and structural strength of touch-control display module.
Include the touch-control display module provided such as any of the above-described inventive embodiments the present invention also provides a kind of terminal.
Remaining part please refers to the prior art, is no longer repeated herein.
Since the touch-control display module that foregoing invention embodiment is provided can effectively prevent false triggering fingerprint identification function,
The terminal that the corresponding embodiment of the present invention is provided can effectively prevent false triggering fingerprint identification function.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with it is other
The difference of embodiment, just to refer each other for same or similar part between each embodiment.
Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by
One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning
Covering non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only that
A little elements, but also include other elements that are not explicitly listed, or further include for this process, method, article or
The intrinsic element of equipment.In the absence of more restrictions, the element limited by sentence "including a ...", is not arranged
Except there is also other identical elements in the process, method, article or apparatus that includes the element.
A kind of touch-control display module provided by the present invention and a kind of terminal are described in detail above.It answers herein
With specific case, principle and implementation of the present invention are described, and the explanation of above example is only intended to help to manage
Solve the method and its core concept of the present invention.It should be pointed out that for those skilled in the art, not departing from
, can be with several improvements and modifications are made to the present invention under the premise of the principle of the invention, these improvement and modification also fall into this hair
In bright scope of the claims.
