SCREEN PROTECTOR BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a protector, and in

particular, to an adsorption screen protector.

2. Description of the Related Art

With the advancement of technology and the development of

the Internet, mobile devices (such as smart phones, tablet

computers, laptops, etc.) have become an indispensable item

in people's lives. Since the mobile devices are very

convenient to carry, they can be used in public occasions such

as offices, public places or public transportation.

In general, the screens of the mobile devices currently

available in the market do not have a peep-prevention function.

Therefore, when the mobile device isusedinpublic, the people

around can easily peek at the display content on the screen,

and the privacy of the user cannot be protected. Based on the

foregoing problems, most of the current coping practices are

to additionally attach a peep-prevention sheet to the screen

of the mobile device to avoid easy peeping by others. However,

the peep-prevention sheet is secured in a pasting mode, and

the user needs to tear it off when it is not needed, and it

is easy to leave residual glue after the tearing, which causes

trouble and re-installation inconvenience. Even if the mobile

device is used in a personal space, and there is no need to

consider privacy protection temporarily, it is stillnot easy

Description

to remove the secured peep-protection sheet. If the

peep-protection sheet is still secured on the screen in a safe

environment, the brightness of the screen will be darkened

and the sharpness of the picture will be reduced, and the

original clear and high-contrast visual perception of the

screen is reduced in long-term use, and thus, it is still

needed to improve the peep-protection sheet.

To solve the foregoing problems, a product which is

composed of a magnetic functional component and the

peep-protection sheet has been developed in recent years. As

shown in Fig. 15A, such peep-protection sheet is to add a

functional component B on the side of either surface of a

protection sheet body A, and dispose the attaching bodies 3

at correspondingpositions around the screen of the electronic

device 2, so that the user can secure the peep-protection sheet

to the surface of the screen or take it down according to actual

needs during use.

However, due to the trendofthinningofthe hardware design

ofthe electronicdevice, when the screen (locatedon the upper

cover) of the electronic device such as a notebook computer

is closed, the space formed by the inner surface of the screen

and the inner surface of the keyboard is very limited. If a

decorative or functional protruding structure is disposed on

the outer surface of the peep-protection sheet, the upper

cover of the notebook computer cannot be smoothly closed, and

the sleep program executed by relevant components of the

Description

notebook computer which are originally triggered by closing

the upper cover would be hindered. Furthermore, since the

peep-protection sheet is effective in preventing peep by

changing the visible light transmittance ofdifferent viewing

angles, when the peep-protection sheet is secured to the

screen surface, the functional component B protruding from

the protection sheet body A may cause the protection sheet

body A to incline toward the other side where no functional

component is installed, and thus the protection sheet body

A cannot be disposed in parallel to the screen surface, as

shown in Fig. 15B, and the user's visibility when viewing the

screen would be affected.

Because the key materials, key technologies and mass

production technologies for producing the viewing angle

limitation effect of the peep-protection sheet have been

mastered by a few material companies in the past 20 years,

the development of the attachment technology of the

peep-protection sheet to the screen of the electronic device

is only limited to attaching a protruding structure at the

outer surface of the peep-protective sheet. Therefore, it is

imperative that all walks of life can develop a novel screen

protector that can achieve the effect of easy and quick

disassembly and assembly, and can also achieve the overall

thinning effect of the screen protector.

Description

SUMMARY OF THE INVENTION

In view of the foregoing problems, the inventors have

diligently studied and searched for various possible

solutions for solving the foregoing problems of the

decorative component (such as a pigment/paint layer or a

pattern film) and the gratingsheetinside the peep-prevention

sheet in the same layer, so as to achieve the overall thinning

effect of the screen protector, thereby solving the technical

problem of how to not inclined or bend the functional

components and two flat components of different materials of

the grating sheet at the junction when they are integrated

into the same layer. Furthermore, the upper cover can be

smoothly closed when the screen protector is used to adsorb

the screen of the notebook computer, so that the notebook

computer can smoothly trigger the sleep program. Moreover,

the solution of the present invention that the screen

protector can achieve the effect ofeasy and quick disassembly

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical means by which the present invention is

intended to achieve the intended inventive purpose is further

illustrated below with the drawings and the preferred

embodiments of the present invention. The accompanying

drawings are provided for reference and description to the

detailed description and technical content of the present

invention only, and are not intended to limit the present

invention. In the following description of the present

invention, the orientation or positional relationships

indicated by the terms "up", "down", "left", "right", "top",

"bottom", "inside", and "outside", etc., are based on the

orientation or positional relationships shown in the drawings,

and are merely intended to facilitate simplifying the

description of the present invention, instead of indicating

that the devices or components in the description must have

a specific orientation and are constructed and operated in

a specific orientation, and thus cannot be understood as the

limitations of the present invention.

The screen protector disclosed in the embodiments of the

present invention is based on the following design

Description

considerations. First, due to the trend of thinning of the

hardware design of the electronic device, when the screen

(located on the upper cover) of the electronic device such

as a notebook computer is closed, the space formed by the inner

surface of the screen and the inner surface of the keyboard

is very limited. If a decorative or functional protruding

structure is disposed on the outer surface of the

peep-protection sheet, the upper cover of the notebook

computer cannot be smoothly closed, and the sleep program

executed by relevant hardware and software of the notebook

computer which are originally triggered by closing the upper

cover would be hindered. Therefore, the screen protector of

the embodiments of the present invention tends not to have

a protruding structure attached to the outer surface thereof

to further reduce the thickness of the screen protector.

However, this will encounter major technical problems.

Because the key materials, key technologies and mass

production technologies for producing the viewing angle

limitation effect of the peep-protection sheet have been

mastered by a few material companies in the past 20 years,

the development of the attachment technology of the

peep-protection sheet to the screen of the electronic device

is only limited to attaching a protruding structure at the

outer surface of the peep-protective sheet. Therefore, the

screen protector of the present invention must overcome the

technical development limitations that are unsustainable for

Description

a long term, that is, the functional components (such as

ferromagnetic attaching members) and/or decorative

components (such as artificial leather or a colored paint

layer) can onlybe designed outside the peep-protection sheet.

In order to solve such a problem, the present invention

integrates the functional components (such as ferromagnetic

attaching members) and/or decorative members (such as a

pigment/paint layer or a pattern film) with a grating sheet

inside the peep-protection sheet in the same layer, so as to

achieve the overall thinning effect of the screen protector.

Furthermore, the upper cover can be smoothly closed when the

screen protector is used to adsorb the screen of the notebook

computer, so that the notebook computer can smoothly trigger

the sleep program. Moreover, the solution that the screen

protector can achieve the effect ofeasy and quick disassembly

and assembly, without adding an externalprotruding structure

can achieve the effect of providing the functional components

and the decorative components on the screen protector. Then,

another technical problem that needs to be overcome when the

functional components and the grating sheet are integrated

on the same layer is how to make two independent planar

components of different materials not be inclined or bent at

the junction.

The followingembodiment drawings of the presentinvention

will be described with reference to the coordinate system of

Fig. 1. The arrow L direction represents the left side, the

Description

arrow R direction represents the right side, the arrow U

direction represents the upper side or the top side, and the

Fig. 1 is an exploded perspective view showing an

embodiment of a screen protector 1 according to the present

invention. In this embodiment, the screen protector 1 is

substantially rectangular and comprises a grating sheet 10

and a first attachingmember 20 disposedbetween a transparent

first outer cover film 30 and a second outer cover film 40.

Amanufacturingmethod ofa screen protector of the present

invention is described in detail below. The manufacturing

method comprises the following steps:

A sheet punching step Sl: sheets constituting the first

outer cover film, the second outer cover film, the grating

sheet, and the first attaching member are cut into specific

sizes, respectively.

A functional layer forming step S2: the grating sheet and

the attaching member are disposed and attached to a front

surface of the second outer cover film to form the functional

layer, and the attaching member is disposed adjacent to the

grating sheet side-by-side.

A semi-finished product forming step S3: a lower surface

of the first outer cover film is bonded to the grating sheet

Description

and the attaching member to form a semi-finished product.

A heating and pressing defoaming step S4: vacuum-pressing

is performed on the semi-finished product under appropriate

conditions, to remove bubbles inside the semi-finished

product, and the surface of the semi-finished product is

flattened to obtain the screen protector.

In the sheet punching step S, the sheets constituting the

first outer cover film 30, the second outer cover film 40,

the grating sheet 10, and the first attaching member 20 are

respectively cut into specific shapes by a punching machine,

the height of a tool face of a cutting die used in the punching

machine is 23.6 mm, and the inclination of tool points on both

sidesis150. In addition, duringpunching ofthe grating sheet

, the punch angle must be adjusted according to the screen

resolution of corresponding electronic device. For example,

if the screen resolution is 1366x768, the punch angle is 11

degrees, and if the screen resolution is 1920x1080, the punch

angle is 15 degrees. In addition, the shape and size of the

screen protector 1 correspondingly match those of a screen

of the electronic device. In this embodiment, the grating

sheet 10, the first outer cover film 30 and the second outer

cover film 40 are substantially rectangular sheets

respectively, and the first attaching member 20 is an

elongated sheet, wherein the first outer cover film 30 and

the second outer cover film 40 are of the same size, and shapes

and sizes of the combined and spliced grating sheet 10 and

Description

the first attaching member 20 are the same as those of the

first outer cover film 30 and the second outer cover film 40.

In different embodiments, the total thickness actually

achieved by the screen protector 1 is preferably only about

0.4-0.50mmplus orminus 5-10%, whichis difficult tovisually

recognize the structure thereof. For convenience of

description, the geometrical proportions of the screen

protector 1 structure in the respective embodiment drawings

are adjusted. Compared with the traditional peep-protection

sheet, the functional component and the decorative component

are disposed on the outer surface of 0.95-1.4 mm plus or minus

-15%, and the screen protector 1 of the present invention

substantially reduces the thickness by 58%-65%, and it

conforms to the space application trend of thinning andnarrow

Then, reference is made to Figs. 1, 2A/2B/2C, and 3A

together. Fig. 2A is a perspective view of an embodiment of

a screen protector 1 of the present invention; Fig. 2B is a

partial enlarged view of a region 2H in Fig. 2A; Fig. 2C is

a partial enlarged view of the region 21 of Fig. 2A; and Fig.

3A is an exploded perspective view of the screen protector

1 and an electronic device 2 of Fig. 1.

In this embodiment, the grating sheet 10 and the first

attaching member 20 are disposed vertically adjacent to each

other side-by-side, and the first attaching member 20 is

disposed above the grating sheet10. In an embodiment, abottom

Description

edge 22 of the first attaching member 20 is aligned with and

adjacent to a top edge 11 of the grating sheet 10, and both

may be adhesively fixed or merely adjacent to each other. In

an example, two side edges 23A/23B of the first attaching

member20 canbe vertically alignedwith two side edges13A/13B

of the grating sheet 10, respectively. In a preferred

embodiment, the attaching member 20 has the same or

approximate thickness as the grating sheet 10, and the

attaching member 20 can also have a smaller thickness than

the grating sheet 10.

In the functional layer forming step S2, the two side edges

13A/13B and a bottom edge 12 of the grating sheet 10 are

respectively aligned with and attached to two side edges

43A/43B and a bottom edge 42 of the second outer cover film

, and the two side edges 23A/23B and a top edge 21 of the

first attaching member 20 are respectively aligned with and

attached to top sections of the top side edges 43A/43B and

a top edge 41 of the second outer cover film 40, so that the

grating sheet 10 and the first attaching member 20 form a

functional layer in the same plane. Then, in the semi-finished

molding step S3, two side edges 33A/33B and a bottom edge 32

of the first outer cover film 30 are respectively aligned with

and attached to the side edges 13A/13B and the bottom edge

12 of the grating sheet 10, and the top sections of the top

side edges 33A/33B and the top edge 31 of the first outer cover

film 30 are respectively aligned with and attached to the two

Description

side edges 23A/23B and the top edge 21 of the first attaching

member 20, thereby forming a semi-finished product of the

screen protector 1.

Then, in the heating and pressing defoaming step S4, an

appropriate pressure P and temperature T are applied to the

semi-finished product for a vacuum-pressing duration X, to

remove bubbles inside the semi-finished product, and the

surface of the semi-finished product is flattened to obtain

the screen protector 1. The pressure P, the temperature T,

and the time X depend on the thickness and material of the

sheet. For example, the pressure P is generally in the range

of0.5 to 30 Kg/cm 2 , preferably in the range of0.5 to 25 Kg/cm 2

, more preferably in the range of 2.5 to 20 Kg/cm 2 , and most

preferably in the range of 2.5 to 15 Kg/cm 2 . In addition, the

temperature T is generally in the range of 30 to 90°C,

preferably in the range of 35 to 80C, more preferably in the

range of 35 to 750C, and most preferably in the range of 35

to 750C. Moreover, the time X is generally in the range of

to 100 min, preferably in the range of 10 to 90 min, more

preferably in the range of 20 to 90 min, and most preferably

in the range of 25 to 80 min.

Through the steps, the top region of the first outer cover

film 30, the first attaching member 20, and the top region

of the second outer cover film 40 form adsorption zones 1A

which are sequentially stacked and have corresponding areas,

and the main region of the first outer cover film 30, the

Description

grating sheet 10, and the main portion of the second outer

cover film40 also formviewing zoneslBwhichare sequentially

stacked and have corresponding areas, below the adsorption

zones 1A.

Therefore, as shown in Fig. 3A, the first attaching member

is disposed in the adsorption zone 1A of the screen

protector 1, so that the screen protector 1 can be

correspondingly adsorbed to an attaching body 3 outside a

screen 4 of an electronic device 2 through the first attaching

member 20. In this embodiment, the electronic device 2 is a

notebook computer, and the attaching body 3 is disposed inside

the electronic device 2 and located above the display screen

4 for aligning the attachingmember 20 of the screen protector

1. In Fig. 3A, the attaching member 20 of the screen protector

1 and the attaching body 3 of the electronic device 2 can be

respectively made ofmagneticmaterials ofdifferent magnetic

poles (for example, one of a group consisting of ferrite,

aluminum-nickel-cobalt alloy, or rare-earth magnets or any

combination thereof); or, one of the first attaching member

and the attaching body 3 is a magnet, and the other is a

ferromagnetic member (for example, a single metal member or

a multi-metal alloy member such as iron, nickel or cobalt that

can be magnetically attracted, which can be used as a part

of a casing or a structural member), so that the first

attaching member 20 and the attaching body 3 can attract each

other. In some embodiments, the first attaching member 20 can

Description

be realized by a thinned elongated metal sheet/metal strip,

a magnetic/ferromagnetic sheet, or a coating containing a

metal or magnetic/ferromagnetic material. Therefore, the

first attaching member 20 can be adsorbed to the attaching

body 3 by using the magnetic attraction principle when the

screen protector 1 approaches the attaching body 3 of the

electronic device 2 with the first attaching member 20, so

that the adsorption zone 1A of the screen protector 1 is fixed

on the electronic device 2, and the viewing zone 1B of the

screen protector 1 covers the display screen 4 of the

electronic device 2 to achieve the effect of avoiding peeping

by others. In addition, if the user has the need for

disassembly, the attaching member 20 of the screen protector

1 can be removed from the attaching body 3 of the electronic

device 2, and the detachment is easy and quick.

Figs. 3B and 3C are respectively exploded perspective

views of the screen protector 1 and the electronic device 2

of Fig. 1. Different from Fig. 3A, in Figs. 3B and 3C, no

attaching member 3 is disposed outside the display screen 4

of the electronic device 2, and the screen protector 1 further

includes a separate attaching body 3T or two attaching bodies

3T', the attaching body 3T/3T' has ferromagnetic properties

and has an adhesive surface for adhering to the outside of

the display screen 4 on the electronic device 2. In Figs. 3B

and3C, the attachingmember 20 and the attachingbodies 3T/3T'

of the screen protector 1 can be respectively made ofmagnetic

Description

materials of different magnetic poles (for example, one of

a group consisting of ferrite, aluminum-nickel-cobalt alloy,

or rare-earth magnets or any combination thereof); or one of

the first attaching member 20 and the attaching bodies 3T/3T'

is a magnet, and the other is a ferromagnetic member (for

example, a single metal member or a multi-metal alloy member

such as iron, nickel or cobalt that can be magnetically

attracted), so that the attaching member 20 and the attaching

bodies 3T/3T' are attract each other. In some embodiments,

the ferromagnetic properties of the attaching member 20 and

the attaching bodies 3T/3T' can be realized by a thinned

elongated metal sheet/metal strip, a magnetic/ferromagnetic

sheet, or a coating containing a metal or

magnetic/ferromagnetic material. In some embodiments, the

thickness of the attaching member 20 can be, for example,

0.1-0.5 mm plus or minus 5-20%, preferably 0.2-0.35 mm plus

or minus 5-20%, and more preferably 0.30-0.35 mmplus or minus

-20%. In different embodiments, the thickness of the

attaching member can be, for example, between 0.4 mm and 0.7

mm, or in the range of 0.4, 0.5, 0.6 or 0.7 mm plus or minus

-20%.

In addition, the attaching member 20 of the screen

protector 1 in Fig. 3A is formed with an opening 24

corresponding to a visual sensor 5 of the electronic device

2 (for example, a camera including a CCD or CMOS component),

the first outer cover film 30 and the second outer cover film

Description

are also respectively formed with openings 34/44

corresponding to the opening24 of the first attachingmember.

Thus, a hollow channel formed by the opening 34, the opening

24 and the opening 44 which are sequentially communicated can

prevent the visual sensor 5 from being covered by the screen

protector 1 to lose its function, after the screen protector

1 is mounted on the electronic device 2. The foregoing opening

34, opening 24 and opening 44 are respectively through holes

defined by a closed inner edge. Certainly, the opening 24 of

the first attaching member 20 and the openings 34/44 of the

first outer covering 30 and the second outer covering 40 can

be formed in different shapes or in different positions, and

other holes can be added as needed, so as to correspond to

the visual sensor 5 or other functional components (such as

a light source, a headphone jack or a function button) of the

electronic device 2. In Fig. 3B, the attaching body 3T has

a shape and size corresponding to the attaching member 20

(extending along the long side of the grating sheet 10 in a

strip shape), and the attaching body 3T has an opening 3T0

corresponding to the opening 24 of the attaching member 20

and the openings 34/44 of the first outer cover film 30 and

the second outer cover film 40 corresponding to the visual

sensor 5 of the electronic device 2 to avoid covering it. In

Fig. 3C, the two attaching bodies 3T' whose width and length

are less than half of the attaching member 20 are first

attached to the outside of the display screen 4 of the

Description

electronic device 2, and the left and right sides of the visual

sensor 5, to avoid covering the visual sensor 5, and can be

adsorbed corresponding to the attaching member 20. In other

words, the attaching body of the embodiments of the present

invention is adsorbed corresponding to the attaching member,

and is affixed to the electronic device by default, or is

freely attached to the outer surface of the electronic device.

Referring to Figs. 4A and 4B, Fig. 4A is a sectional view

of an embodiment of the grating sheet 10 of Fig. 1, and Fig.

4B is a sectional view of another embodiment of the grating

sheet 10 of Fig. 1.

As shownin Fig.4A, the grating sheet10includes two outer

layers 101, 103 and a grating layer 102, but the grating sheet

can also have only one outer layer 103, as shown in Fig.

4B, this embodiment is not limited thereto. The outer layers

101, 103 are resin layers made of high light transmissive

materials. For example, the outer layers 101, 103 are made

of Polyimide (PI), Polyethylene Terephthalate (PET), and

Polycarbonate (PC), Poly-Methyl Methacrylate (PMMA), and

Triacetyl Cellulose (TAC). The grating layer 102 is fixed

between the two outer layers 101, 103. For example, in Fig.

4A, the outer layers 101, 103 are respectively adhered to two

opposite surfaces of the grating layer 102; or as shown in

Fig. 4B, the grating layer 102 is fixed on the outer layer

103.

In Figs. 4A and 4B, the grating layer 102 of the grating

Description

sheet 10 includes a plurality of opaque grating walls 1021,

which are arranged according to the Micro-louver principle.

The light can be limited to a specific angle a by setting the

grating walls 1021 in parallel and equidistantly (i.e., an

upright louver structure). The grating walls 1021 can be

directly printed on the outer layer 103 in a three-dimensional

printing manner (Fig. 4B), or the outer layer 101 is attached

after the grating walls 1021 are formed, so that the grating

layers 102 (the grating walls 1021) are located between the

two outer layers 101, 103. In another embodiment, the grating

layer 102 may be formed by slitting repeatedly stacked

transparent and opaque materials. In other embodiments, the

grating layer 102 is adhered to the outer layers 101, 103

through an adhesive layer, respectively. The grating sheet

has the same or approximate thickness as the attaching

member 20. In some embodiments, the overall thickness of the

grating sheet 10 is in the range of 0.25, 0.30 to 0.35 mm plus

or minus 5-20%. In different embodiments, the thickness of

the attaching member can be, for example, between 0.25 mm and

0.7 mm, or in the range of 0.4, 0.5, 0.6 or 0.7 mm plus or

minus 5-20%. Thus, the grating sheet 10 can only provide a

visible range of a certain angle a, as shown by arrow V in

the figure, which is the angle of facing the grating layer

102 (i.e., a zero angle), since the light is not blocked, the

visibilityis not affected. If the angle deviation is larger,

the brightness is lower, so that the effect of preventing peep

Description

and information confidentiality can be fully achieved. The

change in the viewing angle of the grating sheet 10 can achieve

the effect of preventing peep, which is closely related to

the visible light transmittance of the grating sheet 10 at

various viewing angles. For example, in a set of embodiments,

the visible light of 550 nm wavelength is used to experiment

with the viewing zone 1B of the screen protector 1. At the

viewing angle 0, several sets of light transmittance data such

as 52.13%, 54.16%, 56.66%, 59.86%, 61.55% and 64.22% can be

obtained.At the viewing angle of15, the light transmittance

data can still reach the level of 33.10%, 37.28 % or 46.8%.

However, once the left/right viewing angle of 30° is reached,

the light transmittance data is sharply reduced below 10%,

for example, 2.55%, 5.10% or 8.63%. In these embodiments, the

allowable viewing angle range of the viewing zone 1B of the

screen protector 1 is only about 30 degrees to the left and

right, for a total allowable viewing angle range of about 60

degrees. In other words, the grating sheet 10 and the grating

layer 102 thereof are configured to limit the light passing

through the viewing zone 1B to an allowable viewing angle

range.

The first outer cover film 30 and the second outer cover

film 40 of an embodiment of the present invention can be, for

example, made of PI, PET, PC, PMMA and TAC, and the materials

constituting the first outer cover film30 and the secondouter

cover film40maybe the same ordifferent.For the thicknesses

Description

of the first outer cover film 30 and the second outer cover

film 40, in some embodiments, the thicknesses of the first

outer cover film 30 and the second outer cover film 40 can

be, for example, in the range of 0.05, 0.075, 0.10, or 0.125

mm plus or minus 5-20%, which may include or may not include

the thicknesses of the first outer cover film 30 and the second

outer cover film 40 themselves and one or more coatings. The

grating sheet 10 itself does not have sufficient structural

strength to maintain the screen protector 1 in a flat plane

when the grating sheet 10 itself, in particular only having

a single outer layer 103, provides a support surface for the

grating layer 102. Therefore, with the front and back

attachment of the first outer cover film 30 and the second

outer cover film 40, the grating sheet 10 and the attaching

member 20 can be maintained in the flat plane, that is, the

screen protector 1 can be maintained as a whole in the flat

plane, thereby conforming to the functional requirement of

being flat on the display screen 4 of the electronic device

2 without warping. More importantly, the front and back

attachment of the first outer cover film 30 and the second

outer cover film 40 requires sufficient structural strength

so that two independent planar components, i.e., the grating

sheet 10 and the attaching member 20 are not inclined or bent

atthejunction. Inaddition, in order tomeet the requirements

of no fingerprint left after use, low glare, low reflected

light, and scratchresistance, etc., the inner surfaces and/or

Description

the outer surfaces of the first outer cover film 30 and the

second outer cover film 40 may have one or more coatings, the

coating can be selected from one of a group consisting of an

anti-fingerprint coating (of an ultra-low frictional

coefficient), an anti-glare coating, an anti-reflection

coating, an anti-bluelight coating, and a hard coating, or

any combination thereof. In some experimental examples, the

anti-reflection coating can increase the transmittance of the

screen protector 1 by 8-12%, thereby improving the low

transmittance of the conventional screen protector 1.

In addition, please refer to Fig. 5. Fig. 5 is an exploded

perspective viewofanotherembodiment ofthe screenprotector

1 of the present invention. In this embodiment, the present

invention provides another manufacturing method of a screen

protector as follows:

A sheet punching step Ml: sheets constituting the first

outer cover film, the second outer cover film, the grating

sheet, and the first attaching member are cut into specific

sizes, respectively.

An adhesive layer applying step M2: a viscous adhesive

material is applied to a rear surface of the first outer cover

film and a front surface of the second outer cover film, to

form a first adhesive layer and a second adhesive layer.

A functional layer forming step M3: the grating sheet and

the attaching member are disposed and attached to the front

surface of the second outer cover film to form the functional

Description

layer, and the attaching member is disposed adjacent to the

grating sheet side-by-side.

A semi-finished product forming step M4: the rear surface

of the first outer cover film is bonded to the grating sheet

and the attaching member to form a semi-finished product.

A heating and pressing defoaming step M5: vacuum-pressing

is performed on the semi-finished product under appropriate

conditions, to remove bubbles inside the semi-finished

product, and the surface of the semi-finished product is

flattened to obtain the screen protector.

In this embodiment, the screen protector 1 further

comprises a transparent first adhesive layer 301 and a second

adhesive layer 401 respectively configured to attach the

grating sheet 10 and the first attaching member 20 between

the first outer cover film 30 and the second outer cover film

, so that the screen protector 1 as a whole has a certain

structural strength and can be maintained in the flat plane.

More importantly, the first outer cover film 30 and the second

outer cover film 40 as well as the front and back attachment

of the first adhesive layer 301 and the second adhesive layer

401 can further provide sufficient structural strength, so

that two independent planar components, i.e., the grating

sheet 10 and the first attaching member 20 are not inclined

or bent at the junction. To achieve this objective, in some

embodiments, the overall thickness of the first outer cover

film 30 and the second outer cover film 40 as well as the first

Description

adhesive layer 301 and the second adhesive layer 401 at least

has to reach 1/8 of the thickness of the grating sheet 10 and

the first attaching member 20. In different embodiments, the

overall thickness of the first outer cover film 30 and the

second outer cover film 40 as well as the first adhesive layer

301 and the second adhesive layer 401 can be 1/7, 1/6, 1/5,

1/4, 1/3, 1/2 or 1/1 of the thickness of the grating sheet

and the first attaching member 20, the key is that the

thinner the overall thickness is, the higher the structural

strength of the first outer cover film 30 and the second outer

cover film 40 as well as the first adhesive layer 301 and the

second adhesive layer 401 is required. Moreover, the first

adhesive layer 301 and the second adhesive layer 401 use an

optical cured adhesive of higher hardness after curing, which

also helps to reduce the individual and overall thicknesses

of the first outer cover film 30 and the second outer cover

film 40 as well as the first adhesive layer 301 and the second

adhesive layer 401. The outer peripheries of the first outer

cover film 30 and the second outer cover film 40 correspond

to the outer peripheries of the first adhesive layer 301 and

the second adhesive layer 401. The first adhesive layer 301

is located between the outer cover film 30 and the grating

sheet 10/attaching member 20 for adhering the grating sheet

and the first attaching member 20 to the outer cover film

30. The second adhesive layer 401 is located between the

grating sheet 10 and the first attaching member 20 and the

Description

outer cover film 40 for adhering the grating sheet 10 and the

first attaching member 20 to the outer cover film 40. In some

embodiments, the first adhesive layer 301 and the second

adhesive layer 401 are realized by an Optical Clear Adhesive

(OCA), for example, an optical acrylic adhesive sandwiched

between two release films, and can be cut and formed using

a punching machine. During processing, a release film is

peeled off, and the other release film is peeled off after

the first side is attached, to attach the second side. In an

embodiment, the thicknesses of the first adhesive layer 301

and the second adhesive layer 401 are in the range of about

0.025, 0.035, 0.05, or 0.075 mm plus or minus 5-20%. In Fig.

, the first adhesive layer 301 and the second adhesive layer

401 are respectively formed with openings 301H and 401H, and

the sizes, shapes and positions thereof correspond to the

openings 34/44 of the first outer cover film 30 and the second

outer cover film 40 and the opening 24 of the attaching member

20. Similar to the opening 34, the opening 24, and the opening

44, the openings 301H and 401H are also through holes defined

by a closed inner edge, respectively. In addition, upon

completion of the vacuum-pressing, the overall structural

strength of the screen protector can be further enhanced by

UV light irradiation.

The configuration position/size/shape of the attaching

body and the visual sensor (or other functional components)

at the periphery of the display screen of the electronicdevice

Description

may be different. Therefore, the structure of the screen

protector 1 needs to be slightly adjusted so that the screen

protector 1 can correspond to the attaching body adsorbed at

the periphery of the display screen, the viewing zone 1B can

correspond to the display screen, and the opening 34, the

opening 24 and the opening 44 of the adsorption zone 1A can

correspond to the visual sensor (or other functional

components), and further description is made according to the

following embodiments and related drawings.

Fig. 6 is an exploded perspective view of another

embodiment of the screen protector 1of the present invention.

In Fig. 6, the screen protector 1 includes a first attaching

member 20, a grating sheet 10' and a second attaching member

' sequentially arranged from top to bottom and disposed

between the first outer cover film 30 and the second outer

cover film 40. Specifically, the grating sheet 10' is disposed

between the first attaching member 20 and the second attaching

member 20', and is then coated together between the

transparent first adhesive layer 301 and the second adhesive

layer 401. The first outer cover film 30 and the second outer

cover film 40 are then attached to the outside of the first

adhesive layer 301 and the second adhesive layer 401. The

second attachingmember 20' is locatedbelow the grating sheet

'. The arrangement is such that the screen protector 1 can

also correspond to the attaching body (not shown) disposed

inside the electronic device in an attaching mode and located

Description

below the display screen. The outer peripheries of the first

outer cover film 30 and the second outer cover film 40

correspond to the outer periphery of the first adhesive layer

301/the second adhesive layer 401. The structures and the

relative relationship of the first adhesive layer 301 and the

second adhesive layer 401 are as described above, for

convenience of explanation, in the following description of

the structural relationships of other components, the first

adhesive layer 301 and the second adhesive layer 401 are

omitted. As shown in Fig. 6, the first attaching member 20,

the grating sheet 10' and the second attaching member 20' are

disposedvertically adjacent to each other side-by-side; that

is, the bottom edge 22 of the first attaching member 20 is

aligned with and adjacent to the top edge 11' of the grating

sheet 10', and both may be adhesively fixed or merely adjacent

to each other; and the top edge 21' of the second attaching

member 20' is aligned with and adjacent to the bottom edge

12' of the grating sheet 10', and both may be adhesively fixed

or merely adjacent to each other. In Fig. 6, the top sections

of the two side edges 33A/33B of the first outer cover film

, the two side edges 23A/23B of the first attaching member

, and the top sections of the two side edges 43A/43B of the

second outer cover film 40 are sequentially aligned

horizontally, respectively. The main sections of the two side

edges 33A/33B of the first outer cover film 30, the two side

edges 13A'/13B' of the grating sheet 10' and the main sections

Description

of the two side edges 43A/43B of the second outer cover film

are sequentially aligned horizontally, respectively.

Moreover, the lower sections of the two side edges 33A/33B

of the first outer cover film 30, the two side edges 23A'/23B'

of the second attaching member 20' and the lower sections of

the two side edges 43A/43B of the second outer cover film 40

are sequentially aligned horizontally, respectively.

Similarly, the top edge 31 of the first outer cover film 30,

the top edge 21 of the first attaching member 20, and the top

edge 41 of the second outer cover film 40 are sequentially

aligned horizontally, respectively. Similarly, the bottom

edge 32 of the first outer cover film 30, the bottom edge 22'

of the second attaching member 20' and the bottom edge 42 of

the second outer cover film 40 are sequentially aligned

horizontally, respectively. The technical solution of Fig.

3B is adjusted and can be applied to the embodiment of Fig.

6, that is, for the case where no attaching body is disposed

outside the display screen of the electronic device. The

screen protector 1 in Fig. 6 can further include a separate

attaching body 3T in Fig. 3B attached to the top side of the

display screen of the electronic device and corresponding to

the shape and size of the first attaching member 20 in Fig.

6, and can further include another attaching body attached

to the bottom side of the display screen of the electronic

device and corresponding to the shape and size of the second

attaching member 20' in Fig. 6, so that the attaching bodies

Description

can be adsorbed to each other. Similarly, the technical

solution of Fig. 3C is adjusted and can be applied to the

embodiment of Fig. 6, that is, for the case where no attaching

body is disposed outside the display screen of the electronic

device. The screen protector 1 in Fig. 6 can further include

a separate attaching body 3T' in Fig. 3C correspondingly

attached to the first attaching member 20 in Fig. 6, and can

further include another attaching body corresponding to the

shape and size of the second attaching member 20' in Fig. 6,

so that the attaching bodies can be adsorbed to each other.

Fig. 7 is an exploded perspective view of another

embodiment of the screen protector 1of the present invention.

The difference in Fig. 7 is that the first attaching member

is a substantially rectangular ring-shaped sheet having

a main opening 25 for embedding the grating sheet 10" so that

the outer periphery of the grating sheet 10" includes a top

edge 11", a bottom edge 12", and two side edges 13A"/13B" which

are aligned with and adjacent to each other. The inner

periphery of the main opening 25 of the first attaching member

includes four inner edges 251/252/253/254. In this way,

if the periphery of the display screen of the electronicdevice

is provided with the attaching bodies, the screen protector

1 in Fig. 7 can be correspondingly adsorbed by the rectangular

ring-shaped first attaching member 20 thereof, and the

rectangular ring-shaped first attaching member 20 matches the

grating sheet 10 of corresponding size and shape, and can be

Description

implemented in the screen protector 1 of Figs. 1, 2A and 3A

instead of corresponding members, which is implemented in

common with different technical solutions in the respective

figures. The technical solution of Fig. 3B is adjusted and

can be applied to the embodiment of Fig. 7, that is, for the

case where no attaching body is disposed outside the display

screen of the electronic device. The screen protector 1 in

Fig. 7 can further include a separate attaching body 3T in

Fig. 3B that is a rectangular ring-shaped sheet attached

outside the display screen of the electronic device and

corresponding to the shape and size of the attaching member

in Fig. 7 to be adsorbed to each other. Similarly, the

technical solution of Fig. 3C is adjusted and can be applied

to the embodiment of Fig. 7, that is, for the case where no

attaching body is disposed outside the display screen of the

electronicdevice. The screen protector 1in Fig. 7 can further

include one or more separate attaching bodies 3T' in Fig. 3C

attached outside each side of the display screen of the

electronic device and correspondingly adsorbed to the

attaching member 20 in Fig. 7.

Referring to Figs. 8A and 8B, Fig. 8Ais a perspective view

of another embodiment of the screen protector 1 of the present

invention, and Fig. 8B is a partial enlarged view of a region

8H of Fig. 8A. The difference between this embodiment and the

embodiment of Figs. 2A/2B is that the opening 34', the opening

24' and the opening 44' are respectively notches that are open

Description

on one side anddefinedbyinneredges 341/342/343, inner edges

241/242/243 and inner edge 441/442/443 of three sides. The

opening 34', the opening 24' and the opening 44' correspond

to each other in shapes and positions, and can be substantially

trapezoidal or rectangular. The opening 34', the opening 24'

and the opening 44' in Figs. 8A and 8B can be implemented in

the screen protector 1 of Figs. 1, 2A/2B, 3A, and 6/7 instead

of corresponding members, which is implemented in common with

different technical solutions in the respective figures. When

applied to Figs. 6/7, the openings 301H and 401H (not shown)

of the first adhesive layer 301 and the second adhesive layer

401correspond to the openings 34'/44' of the first outer cover

film 30 and the second outer cover film 40, and the opening

24' of the attaching member 20 in sizes, shapes and positions.

Similar to the opening 34', the opening 24' and the opening

44', in this example, the openings 301H and 401H are also

rectangular or trapezoidal notches that are open at one side

and defined by inner edges of three sides, as shown in Fig.

8C (applying the opening 34'/24'/44' in Fig. 8A/8B to the

embodiment of Fig. 6) and Fig. 8D (applying the solution of

the opening 34'/24'/44' in Figs. 8A/8B to the embodiment of

Fig. 7). The technical solution of Fig. 3B is adjusted and

can be applied to the embodiments of Figs. 8A/8B, that is,

for the case where no attaching body is disposed outside the

display screen of the electronic device. The screen protector

1 in Figs. 8A/8B can further include a separate attaching body

Description

3T in Fig. 3B that is attached to the top side of the display

screen of the electronic device and corresponding to the shape

and size of the attaching member 20 in Figs. 8A/8B

(strip-shaped and extending in the long side of the grating

sheet 10, and the opening 3T0 is changed into a notch in Figs.

8A/8B) to be adsorbed to each other. Similarly, the technical

solution of Fig. 3C is adjusted and can be applied to the

embodiment of Figs. 8A/8B, that is, for the case where no

attaching body is disposed outside the display screen of the

electronic device. The screen protector 1 in Figs. 8A/8B can

further include one or more separate attaching bodies 3T' in

Fig. 3C attached to the top side of the display screen of the

electronic device and correspondingly adsorbed to the

attaching member 20 in Figs. 8A/8B.

Referring to Figs. 9A and 9B, Fig. 9Ais a perspective view

of another embodiment of the screen protector 1 of the present

invention, and Fig. 9B is a partial enlarged view of a region

9H of Fig. 9A, and both Figs. 9A and 9B omit the first adhesive

layer 301 and the second adhesive layer 401. The difference

between this embodiment and the embodiments of Figs. 8A/8B

is that the original integrated first attaching member 20 is

separatedby a gap 24" into two semi-attaching members 20L/20R,

which are defined between the left semi-attaching member 20L

and the right semi-attaching member 20R, so that the

semi-attaching members 20L and 20R are completely

disconnected, disposed at the left and right sides and aligned

Description

with each other. The vertical depth of the gap 24" is equal

to the short side lengths of the semi-attaching members 20L

and 20R, and the long side lengths of the semi-attaching

members 20L and 20R are less than half the long side length

of the grating sheet 10. The first outer cover film 30 and

the second outer cover film 40 respectively have openings

34"/44" which respectively correspond to the gaps 24" in sizes,

shapes and positions and can be substantially trapezoidal or

rectangular. The openings 34"/44" are open on one side and

are defined by inner edges 347/348/349 and inner edges

447/448/449 of three sides, respectively. The gap 24" between

the semi-attaching member 20L and the semi-attaching member

R is defined by the side edge 247 of the semi-attaching

member 20L, the side edge 249 of the semi-attaching member

R, and the middle top edge 118 of the grating sheet 10. The

semi-attaching member 20L and the semi-attaching member 20R

are respectively disposed vertically adjacent to the grating

sheet 10 side-by-side; that is, the bottom edge 22L of the

semi-attaching member 20L is vertically aligned with and

adjacent to the left top edge 11L of the grating sheet 10,

and both may be adhesively fixed or merely adjacent to each

other; and the bottom edge 22R of the semi-attaching member

R is aligned with and adjacent to the right top edge 11R

of the grating sheet 10, and both may be adhesively fixed or

merely adjacent to each other. The left top edge 31L of the

first outer cover film 30, the top edge 21L of the

Description

semi-attaching member 20L, and the left top edge 41L of the

second outer cover film 40 are sequentially aligned

horizontally, respectively. Similarly, the right top edge 31R

of the first outer cover film 30, the top edge 21R of the

semi-attaching member 20R, and the right top edge 41R of the

second outer cover film 40 are sequentially aligned

horizontally, respectively.

The technical solutions of the semi-attaching member 20L

and the semi-attaching member 20R that are completely

disconnected and disposed at the left and right sides, the

opening 34" of the first outer cover film 30/the gap 24"/the

opening 44 of the second outer cover film 40 in Figs. 9A and

9B can be applied to the screen protector 1 of Figs. 1, 2A/2B,

3A, and 5/6/7. When the technical solutions in Figs. 9A and

9B are applied to Figs. 5/6/7, the openings 301H and 401H (not

shown) of the first adhesive layer 301 and the second adhesive

layer 401 correspond to the openings 34"/44" of the first outer

cover film 30 and the second outer cover film 40, and the gap

24" between the semi-attaching member 20 and the

semi-attachingmember 20' in sizes, shapes andpositions.When

the technicalsolutionsin Figs.9Aand 9Bare applied to Figs.

/6, the openings 301H and 401H in Figs. 5/6 are similar to

the openings 34", the openings 24" and the openings 44" in

Figs. 9A and 9B, that is, the openings 301H and 401H in Figs.

/6 are also rectangular or trapezoidal notches that are open

at one side and defined by inner edges of three sides,

Description

respectively, as shown in Fig. 9C. When the technical

solutions in Figs. 9A and 9B are applied to Fig. 7, two

semi-attaching members 20L/20R are annularly connected along

the outer periphery of the grating sheet 10" to form a ring

shape, and are formed with a main opening 25 for embedding

the grating sheet 10", so that the outer periphery of the

grating sheet 10" is adjacent to the inner periphery of the

main openings 20 of the two semi-attaching members 20L/20R,

as shown in Fig. 9D.

Fig. 10A is a perspective view showing another embodiment

of the screen protector 1 according to the present invention.

The main difference between Figs. 10A and 9A is that one or

more corners of the bottom edge 12 of the grating sheet 10

of the screen protector 1 in Fig. 10A are truncated and

retracted into one or two truncated sides 14/14' (which are

linear and located at opposite sides of the two semi-attaching

members 20L/20R in Fig. 10A), and the screen protector 1

further includes one or more third attaching members 50/50'

respectively aligned with the grating sheet 10 and adjacently

disposed outside the truncated sides 14/14' of the grating

sheet 10. The third attaching member 50 has an inner side 51

(which is linear in Fig. 10A), and a bottom side 52 and a

vertical side 53 which are respectively connected to two outer

ends of the inner side 51 and are substantially perpendicular

to each other (so that the third attaching member 50 is

substantially triangular). The third attachingmember 50' has

Description

an inner side 51' (which is linear in Fig. 10A), and a bottom

side 52' and a vertical side 53' which are respectively

connected to two outer ends of the inner side 51' and are

substantially perpendicular to each other (so that the third

attaching member 50' is substantially triangular). Moreover,

the truncated side 14 of the grating sheet 10 is aligned with

and adjacent to the inner side 51 of the third attaching

members 50, andbothmaybe adhesively fixed ormerely adjacent

to each other; and the truncated side 14' of the grating sheet

is aligned with and adjacent to the inner side 51' of the

third attaching member 50', and both may be adhesively fixed

or merely adjacent to each other. The third attaching members

/50' are respectively adhered to two bottom corners between

the first outer cover film 30 and the second outer cover film

in Fig. 10A. In Fig. 10A, the lower sections of two side

sides 33A/33B of the first outer cover film 30, the vertical

sides 53/53' of the third attaching members 50/50' and the

lower sections of two side edges 43A/43B of the second outer

cover film 40 are sequentially aligned horizontally,

respectively. Similarly, two outer sections of the bottomedge

32 of the first outer cover film 30, the bottom side 52/52'

of the third attaching member 50/51' and two outer sections

of the bottom edge 42 of the second outer cover film 40 are

sequentially aligned horizontally, respectively.

Although the two semi-attaching members 20L/20R, the

grating sheet 10, and the third attaching members 50/50' are

Description

independent members, they are simultaneously adhered between

the first outer cover film 30 and the second outer cover film

to maintain a certain structural strength, so that the

screen protector 1 can maintain a the flat surface and would

not warp. The effect that the third attaching members 50/50'

prevent the screen protector 1 from warping is particularly

prominent in the implementation of a large-sized screen

protector 1 (for example, the diagonalis more than 20 inches).

Certainly, if the display screen 4 of the electronic device

2 is provided with an attaching body 3 at the corner of the

bottom side, the third attaching members 50/50' are the

attaching body 3 correspondingly adsorbed at the corner of

the bottom side of the display screen 4 of the electronic

device 2.

The technical solution that the grating sheet 10 having

retracted truncated sides 14/14' matches the third attaching

members 50/50' having vertical sides 53/53', bottom sides

52/52' and inner sides 51/51' in Fig. 10A can be implemented

in the screen protector 1 in Figs. 1, 2A/2B, 3A and 5/8A/9A

instead of the corresponding members, which is implemented

in common with different technicalsolutions in the respective

figures, as applied to the embodiment of Fig. 8A, as shown

in Fig. 10B.

Fig. 11A is a perspective view showing another embodiment

of the screen protector 1 according to the present invention.

The main difference between Figs.11Aand10Ais that the third

Description

attaching members 50/50' are substantially L-shaped sheets

as a whole. Specifically, one or more corners of the bottom

edge 12 of the grating sheet 10 of the screen protector 1 in

Fig. 11A are notched to form one or more pairs of truncated

sides 141/142 and/or 141'/142' which are approximately

perpendicular to each other (inverted L-shaped in Fig. 11A),

and the screen protector 1 further includes one or more third

attaching members 50/50' respectively aligned with the

grating sheet 10 and adjacently disposed outside the pair of

truncated sides 141/142 and/or 141'/142' of the grating sheet

10. The third attaching member 50 has a pair of inner sides

511/512 (which are inverted L-shaped in Fig. 10A), and the

bottom side 52 and the vertical side 53 which are respectively

connected to two outer ends of the pair of inner sides 511/512

and are substantially perpendicular to each other (so that

the third attaching member 50 is substantially rectangular).

The third attaching member 50' has a pair of inner sides

511'/512' (which are inverted L-shaped in Fig. 10A), and the

bottom side 52' and the vertical side 53' which are

respectively connected to two outer ends of the inner sides

511'/512' and are substantially perpendicular to each other

(so that the third attaching member 50' is substantially

rectangular). Moreover, the pair of truncated sides 141/142

of the grating sheet 10 are respectively aligned with and

adjacent to the pair of inner sides 511/512 of the third

attaching members 50, and both may be adhesively fixed or

Description

merely adjacent to each other; and the truncated side

141'/142' of the grating sheet 10 are respectively aligned

with and adjacent to the pair of inner side 511'/512' of the

third attaching member 50', and both may be adhesively fixed

or merely adjacent to each other.

The technical solution that the grating sheet 10 having

a pair of truncated sides 141/142 and 141'/142' notched at

the bottom side matches the third attaching members 50/50'

having the vertical sides 53/53', the bottom sides 52/52' and

a pair of inner sides 511/512 and 511'/512' in Fig. 11A can

be implemented in the screen protector 1 in Figs. 1, 2A/2B,

3A and 5/6/7/8A/9A/10A instead of the corresponding members,

which is implemented in common with different technical

solutions in the respective figures, as Fig. 11A is applied

to the embodiment of Fig. 8A, as shown in Fig. 11B. Although

the third attaching members 50/50' of Figs. 10A/11A are

right-triangular or L-shaped, in different embodiments, the

third attachingmembers 50/50' can also be rectangles or other

polygons having different aspect ratios.

Referring to Figs. 12A and 12B, Fig. 12A is a perspective

view of another embodiment of the screen protector 1 of the

present invention, and Fig. 12B is a partial enlarged view

of a region 12H of Fig. 12A. The difference between this

embodiment and the embodiments of Figs. 8A/8B is that the

screen protector 1 has a tab 60 which may be in the shape of

a rectangle, a trapezoid or other polygons. In Figs. 12A and

Description

12B, the tab 60 can be formed by pressing and laminating lugs

/45 which extend from the first outer cover film 30 and the

second outer cover film 40, and is located outside the grating

sheet 10. Since the grating sheet 10 does not extend outward,

a gap is formed when the lugs 35/45 of the first outer cover

film 30 and the second outer cover film 40 are laminated to

form the tab 60, and a sealant 601 (for example, the OCA) can

be filled. Fig. 12C is a partially enlarged perspective view

showing another embodiment of the screen protector according

to the present invention. In Fig. 12C, the tab 60 is formed

by pressing and laminating the lugs 35/45 which extend from

the first outer cover film 30 and the second outer cover film

, and the lug 15 which extends from the grating sheet 10.

In addition, in different embodiments, the tab 60 can be

disposed on either side of the outer side of the grating sheet

, and can be disposed on either side of the outer side of

the attaching member 20, or located at either side of the outer

side of a junction of the grating sheet 10 and the attaching

member 20.

Referring to Figs. 13A/13B/13C, Fig. 13A is a partially

enlarged perspective view of another embodiment of the screen

protector 1 of the present invention, Fig. 13B is a partially

enlarged perspective view of another embodiment of the screen

protector 1 of the present invention, and Fig. 13C is a

partially enlarged perspective view of another embodiment of

the screen protector 1 of the present invention. Fig. 13A is

Description

a stereoscopic structure showing that the screen protector

1 is formed by sequentially laminating the outer cover film

, the first adhesive layer 301, the attaching member 20 and

the grating sheet 10 vertically adjacent to each other, the

second adhesive layer 401 and he outer cover film 40, at the

junction of the grating sheet 10 and the attaching member 20,

which is similar to the structure disclosed in Figs. 5 and

6. Fig. 13B shows that the screen protector 1 further includes

a decorative layer 71 located between the rear side of the

first adhesive layer 301 and the front side of the attaching

member 20, and is similar in shape and position to the

attaching member 20. The decorative layer 71 can be realized

by spraying a pigment or paint or printing a pattern on the

front surface of the attaching member 20 or attaching a thin

film having a printed pattern to the surface of the attaching

member 20 prior to processing. The decorative layer 71 has

an outer periphery 710 aligned with the top edges 31/41 and

the side edges 33A/33B and 43A/43B of the first outer cover

film 30 and the second outer cover film 40, and the top edge

21 and the side edge 23B of the first attaching member 20.

Moreover, the decorative layer 71has abottomedge 711aligned

with and adjacent to the front top edge 111 of the grating

sheet 10, and the bottom edge 22 of the attaching member 20

is still aligned with and adjacent to the main top edge 110

of the grating sheet 10, that is, the bottom edge 711 of the

decorative layer 71 and the bottom edge 22 of the attaching

Description

member 20 together are aligned with and adjacent to the top

edge 11 of the grating sheet 10 (the front top edge 111 and

the main top edge 110). In this way, the decorative component

can also be implemented inside the screen protector 1, that

is, the decorative component is in the same layer as the

grating sheet 10, so that the screen protector 1 can be

thinned.

Fig. 13C is different from Fig. 13B in that the screen

protector 1 further includes another decorative layer 72,

similar to the decorative layer 71, located between the rear

surface of the first attaching member 20 and the front surface

of the second adhesive layer 401. Although the visualelements

such as materials, processing methods, patterns, and colors

used for decoration may be different, both the decorative

layer 71 and the decorative layer 72 are for decorative

purposes. The decorative layer 72 has an outer periphery 720

aligned with the top edges 31/41 and the side edges 33A/33B

and 43A/43B of the first outer cover film 30 and the second

outer cover film 40, and the top edge 21 and the side edge

23B of the first attachingmember 20.Moreover, the decorative

layer 72 has a bottom edge 721 aligned with and adjacent to

the rear top edge 112 of the grating sheet 10, and the bottom

edge 22 of the first attaching member 20 is still aligned with

and adjacent to the main top edge 110 of the grating sheet

, that is, the bottom edge 711 of the decorative layer 71,

the bottom edge 22 of the first attaching member 20 and he

Description

bottomedge 721of the decorative layer 72 together are aligned

with and adjacent to the top edge 11 of the grating sheet 10

(the front top edge 111, the main top edge 110 and the rear

top edge 112). In this way, both sides of the screen protector

1 can be used as front and back sides, which is beneficial

to the user's free application.

The decorative layers 71 and/or 72 in Figs. 13B/13C is

disposed on the front surface and/or the rear surface of the

attaching member 20, and this solution can be implemented in

the screen protector 1 in Figs. 1, 2A/2B, 3A, 5/6/7, 8A/8B,

9A/9B, 10A/11, and 12A/12B/C instead of corresponding members,

which is implemented in common with different technical

solutions in the respective figures. For example, the

decorative layers 71 and/or 72 can also be disposed on the

front surface and/or the rear surface of the first attaching

member, the second attaching member, and/or the third

attaching member. In Figs. 13B and 13C, the decorative layers

71/72 are disposed on the front surface/rear surface of the

first absorbing member 20, and in other embodiments, the

decorative layers 71/72 can also be respectively disposed on

the front surface and/or the rear surface of the first outer

cover film 30 and the second outer cover film 40, and have

the sizes, shapes and positions substantially corresponding

to the attaching member 20.

Fig. 14A is a perspective view showing another embodiment

of the screen protector 1 according to the present invention.

Description

The screen protector 1 in Fig. 14A differs from the foregoing

figures in that the first attaching member 20 extends along

the short side of the grating sheet 10, and the openings

34/301H/24/401H/44 are located on the screen protector 1 or

the first absorbing member 20 on the short side of the grating

sheet 10, and the electronic device 2 to which it is applied

is a tablet computer, and the visual sensor 5 is located on

the electronic device 2 and the short side of the display

screen 4.

The openings 34/301H/24/401H/44 in Fig. 14A are located

on the screen protector 1 or the absorbing member 20 on the

short side of the grating sheet 10, and this solution can be

implemented in the screen protector 1 in Figs. 1, 2A/2B,

3A/3B/3C, 5/6/7, 8A/8B 9A/9B, and 10A/11/12/13 instead of

corresponding members, which is implemented in common with

different technical solutions in the respective figures. Fig.

Description

the embodiment of Fig. 7.

Next, the bending stiffness test of the screen protector

is performed, and the test samples, test methods, and results

are as follows:

Embodiment 1

Sample Ais the screen protector of the present invention,

and the structure thereof is shown in Fig. 5. Sample B is the

screen protector having the structure shown in Fig. 15. Sample

C is a commercially available screen protector having no

attaching member. Sample A, Sample B, and Sample C all have

a dimension of 29.5 cm x 20 cm and a thickness of 450 pm, and

are formed with openings at an intermediate position near a

long side.

First, a 100 gram weight is respectively fixed on one side

of Sample A, Sample B and Sample C, and is a load-bearing end

near the short side; then, the load-bearing ends of Sample

A, Sample B, and Sample C extend from the table top by 11 cm,

so that the load-bearing end is vacated, the force applied

by the weight to the load-bearing end is bent downward, and

the other ends of Sample A, Sample B and Sample C are fixed

on the table top with a weight of 1000 gram.

Then, the vertical distance between the load-bearing ends

ofSample A, Sample B and Sample C and the table topis measured

with a light gauge and recorded in Table 1, and then the

horizontal table top is set to 0 degree, and the included angle

of the load-bearing end and the horizontal table top is

Description

calculated, i.e., the sag of each sample, and the values are

shown in Table 1.

Next, the sags of Sample A, Sample B, and Sample C are

calculated as the bending stiffness (%) by using 0 as 100%

and 90 degrees as 0%, and are recorded in Table 1.

Table 1 Sample A Sample B Sample C Vertical distance (mm) 37.5 58.01 60.02 Sag (degree) 19 31 33 Bending stiffness (%) 79 65.5 63.4 It can be known from the results of Table 1 that the bending

stiffness of Sample Ais increased by 13.5% relative to Sample

B, and is increased by about 15.6% relative to Sample C.

Therefore, the screen protector of the present invention has

a significantly better bending resistance than the screen

protector of the prior art, and is not easily deformed by

external force.

Embodiment 2

In this embodiment, the used sample and the test method

are the same as those in Embodiment 1, except that during the

test, the load-bearing ends of Sample A, Sample B, and Sample

C extend from the table top by 14.9 cm, which is about the

midline position of the long side of the sample and also the

setting position of the opening. The vertical distance, the

sag, and the bending stiffness (%) of the load-bearing end

of each sample to the table top are shown in Table 2.

Description

Table 2 Sample A Sample B Sample C Vertical distance (mm) 67.5 98.1 114 Sag (degree) 24 37 41 Bending stiffness (%) 73 58.9 54.4

It canbe known from the comparison of the results ofTables

1 and 2 that the bending stiffness of Sample A, Sample B, and

Sample C is reduced compared with that of Sample A, Sample

B, and Sample C in Embodiment 1, except that the extension

length of the load-bearingendis longer, the midline position

of the long side of the sample is also formed with an opening,

which also causes the unevenness of the force to reduce the

bending stiffness. Moreover, in this embodiment, the bending

stiffness of Sample Ais increasedby 14.1% relative to Sample

B, and is increased by 18.6% relative to Sample C, and the

increase amplitudes thereof are superior to the results shown

in Embodiment 1, it is indicated that even at the position

where the opening is formed, the screen protector of the

present invention still has a significantly better bending

resistance than the screen protector of the prior art, and

is not easily deformed by the external force.

In summary, the screen protector of the embodiments of the

present invention reverses the design direction of the

externally added components that have not been solved for

decades, and the attaching member is disposed adjacent to the

grating sheet side-by-side, and is coated with, at the front

and back, the two outer cover films. The functional components

Description

and decorative components are successfully integrated into

the same layer as the grating sheet, and the screen protector

is further thinned while maintaining its original fast

adsorption removal function and decorative requirements.

Moreover, the screen protector of the embodiments of the

present invention can provide sufficient structural strength

through two outer cover films and the UV-curing attachment

of the first adhesive layer and the second adhesive layer,

so that two independent planar components, i.e., the grating

sheet and the absorbing member are not inclined or bent at

the junction.

The description of the disclosed embodiments is provided

to enable a person skilled in the art to make or use the present

invention. Various modifications to these embodiments are

obvious to a person skilled in the art, and the general

principles defined herein can be implemented in other

embodiments without departing from the spirit or scope of the
