Specific embodiment
Below in conjunction with the drawings and specific embodiments to flexible protective film proposed by the present invention and its manufacture method and display
Device is described in further detail.According to following explanation and claims, advantages and features of the invention will become apparent from.Need
Bright, accompanying drawing in the form of simplifying very much and uses non-accurately ratio, only conveniently, lucidly to aid in illustrating
The purpose of the embodiment of the present invention.
Fig. 1 is refer to, it is the structural representation of the flexible protective film of the embodiment of the present invention.As shown in figure 1, described soft
Property protective film 10 includes：Flexible parent metal 11 and the hard particles 12 being distributed in the flexible parent metal 11.
Specifically, the flexible parent metal 11 is made of clear material, can be using polymeric materials such as PC, PET, PEN, PES, PI
Material.In the present embodiment, for PI, PI has the advantages that pliability is good, workable to the material that the flexible parent metal 11 is adopted, and is
The flexible parent metal being widely adopted at present.
Please continue to refer to Fig. 1, although the flexible parent metal 11 is frivolous, but still with certain thickness, the flexible parent metal
Hard particles 12 are filled with 11, the hard particles 12 are not uniformly distributed in the flexible parent metal 11, but along
The thickness direction of the flexible parent metal 11 is varied from.Wherein, the hard particles 12 have in the bottom surface of the flexible parent metal 11
There is the first particle density, the hard particles 12 have the second particle density in the top surface of the flexible parent metal 11, described first
Particle density is more than second particle density.That is, the hard particles 12 of the described bottom surface of flexible parent metal 11 are described soft than comparatively dense
The hard particles 12 of the property top surface of base material 11 are than more loose.
Preferably, the density of the hard particles 12 from the bottom surface of the flexible parent metal to the top surface of the flexible parent metal by
It is decrescence little.
The big bottom surface of hard particles density in the flexible parent metal 11, it is thin as the flexible protective through surface grinding
The front 10a of film 10, towards user.The particle density of the front 10a of the flexible protective film 10 is big, therefore hardness is high, resists
Scratch performance good.The little top surface of hard particles density in the flexible parent metal 11, as the reverse side of the flexible protective film 10
10b, towards protected surface.
In the present embodiment, the flexible parent metal 11 and hard particles 12 are made of clear material, therefore the flexible guarantor
Shield film 10 has good translucency.
In the present embodiment, by filling transparent hard particles 12 in the flexible parent metal 11, and in the flexibility
Different particle distributions are formed in base material 11 so that the flexible protective film 10 can take into account flexibility and hardness.
Accordingly, the present invention also provides a kind of manufacture method of flexible protective film.It is described incorporated by reference to referring to figs. 1 to Fig. 4
The manufacture method of flexible protective film includes：
Step one：One flexible parent metal 10 is provided；
Step 2：Hard particles 12 are injected in the flexible parent metal 11.
Specifically, first, as shown in Figure 2, there is provided a flexible parent metal 11, the flexible parent metal 11 is frivolous and pliability pole
The polymeric substrates such as good plastic base, such as PC, PET, PEN, PES, PI.
Then, hard particles 12 are injected in the flexible parent metal 11 by Shooting Technique.Wherein, the hard particles 12
It is made of clear material, is hard transparent particle.In the present embodiment, the hard particles 12 are zinc oxide (ZnO), titanium dioxide
(TiO2) or the transparent particles such as PVC.In injection molding process, the particle distribution of the hard particles 12 is controlled so that described
Hard particles 12 are uniformly distributed in the flexible parent metal 11.As shown in figure 3, after the completion of Shooting Technique, the hard particles 12
In being uniformly distributed in the flexible parent metal 11.
Inject in the flexible parent metal 11 after hard particles 12, the flexible parent metal 11 for being injected with hard particles 12 is quiet
Put, and curing molding.In the process, the hard particles 12 are moved under gravity.As shown in figure 4, when standing one section
Between after, the density of the hard particles 12 gradually increases from a lateral opposite side of the flexible parent metal 11.
In the present embodiment, it is distributed by controlling the particle of the hard particles 12 in injection process so that the hard
Particle 12 is uniformly distributed in the flexible parent metal 11, afterwards by standing the particle for changing the hard particles 12 distribution, is made
Its density is gradually increasedd or decreased along the thickness direction of the flexible parent metal.
In other embodiments, the particle distribution of the hard particles can be directly controlled in injection process so as to close
The thickness direction spent along the flexible parent metal is gradually increasedd or decreased, without the need for standing, direct curing molding.
Finally, surface grinding is carried out to the bottom surface (i.e. the big side of hard particles density) of the flexible parent metal, by table
Face grinding increases the hardness of the bottom surface.As shown in figure 1, after surface grinding, concentrating on the surface of the flexible parent metal
There are hard particles 12, the hard particles 12 cause the case hardness of the flexible parent metal to be improved.
So far, the making of the flexible protective film 10 is completed.Wherein, the flexible parent metal 11 gives the flexible guarantor
The overall flexibility of shield film 10, the hard particles 12 cause the flexible protective film 10 to have good case hardness,
Damage resistant.
Accordingly, the present invention also provides a kind of display device.Please continue to refer to Fig. 1, the display device includes：As above institute
The flexible protective film 10 stated and display floater (not shown), the flexible protective film is covered and the display floater
On, for protecting the display floater.
Wherein, the little side of hard particles density is described soft towards the display floater in the flexible protective film 10
The big side of hard particles density is towards user in property protective film 10.
In the present embodiment, the display floater is flexible display panels.Accordingly, the display device is Flexible Displays dress
Put.
It will be recognized by those skilled in the art that the present invention has no particular limits for the type of the display device, can
It is aobvious to be organic light-emitting display device, or liquid crystal indicator, plasm display device or other kinds of flat board
Showing device.
To sum up, in flexible protective film provided in an embodiment of the present invention and its manufacture method and display device, by
Hard particles are filled in flexible parent metal so that the flexibility and hardness of the flexible protective film is taken into account, not only resistant to bending but also resistance to
Scratch.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this
Any change, modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
