detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 4 , the function of the curved screen protective film of the present invention is to enable the screen protective film to completely cover and adhere to the curved screen. The curved screen protective film of the embodiment of the utility model includes a main film part, which is composed of a peripheral part 2 and a tempered glass part 1 embedded in the peripheral part 2, and the tempered glass part 1 corresponds to the central plane display area of the curved screen Set, the periphery of peripheral portion 2 is the arc edge corresponding to the peripheral arc surface area of curved surface screen; Bottom plate portion 21, pastes on the inner surface of main film portion; With paste layer 3, paste layer 3 is arranged on the inside of bottom plate portion 21 On the side, for snug fit of the curved screen protector to the curved screen. Wherein, because the toughened glass part 1 has high hardness and is not easy to be bent and formed, it is preferred that the tempered glass part 1 is located in the central plane display area of the curved screen, and more preferably the size of the tempered glass part 1 is the same as that of the central plane display area of the curved screen , in the form of a flat plate, the glass surface hardness reaches 7-9H, and the minimum bearing force is 5KG; in order to ensure the appearance of the curved screen protective film of the present invention is smooth, the thickness of the preferred peripheral part 2 is exactly the same as the thickness of the toughened glass part 1; in order to To avoid gaps when the tempered glass part 1 is embedded, it is preferable that the peripheral part 2 is formed by punching out a part with exactly the same shape as the tempered glass part 1 in the center of the plate from a complete plate. As shown in FIG. 4, adhesive 7 is applied to the inner surface and side edges of the tempered glass part 1, the inner surface of the peripheral part 2, and the side where the bottom plate part 21 and the peripheral part 2 are pasted, and the peripheral part 2 overlaps with the bottom plate part 21. Embed the tempered glass part 1 while pasting, the tempered glass part 1, the peripheral part 2 and the bottom plate part 21 are closely pasted together by the adhesive 7 and the pressing effect, after the adhesive 7 is completely dried, further, through high temperature shaping, Make the periphery of the peripheral portion 2 form the same shape (ie arc edge) as the peripheral arc portion of the curved screen, thereby making the curved screen protective film of the present invention have the same shape as the curved screen.

Among them, in order to ensure the toughness and light transmittance of the curved screen protective film of the present invention, the material of the peripheral part 2 is preferably PC substrate or PMMA substrate, which has high transparency and thermoplasticity and is highly transparent and easy to mold. In addition, the adhesive 7 can be super glue, AB glue or shadowless glue (UV glue).

Since the size of the tempered glass part 1 is preferably the same as the size of the central plane display area of the curved screen, the area where the adhesive 7 is located coincides with the edge area of the central display screen of the curved screen of the device, and the tempered glass part 1 and the peripheral part 2 can be further reduced. The visibility of the bonded area improves aesthetics without any adverse effect on the display of the device.

In order to control the thickness of the curved screen protection film of the present invention, ensure the strength of the curved screen protection film of the present invention and reduce the overall weight of the curved screen protection film of the present invention, the thickness of the tempered glass part 1 and the peripheral part 2 is preferably 0.1 to 0.4 mm, more preferably 0.15 to 0.25 mm. The thickness of the bottom plate portion 21 is preferably smaller than that of the tempered glass portion 1 and the peripheral portion 2 .

It includes anti-fingerprint film, anti-scratch film and explosion-proof film in turn, or only any one of them. The functional film can be formed by coating liquid materials. The anti-fingerprint film is preferably a protective film coated with a frosted layer; the anti-scratch film is preferably made of PET material; the material of the explosion-proof film is preferably PC plastic.

In order to make the protective film stick closely to the curved screen, the utility model also includes a sticking layer 3, which is a double-sided adhesive layer/adhesive layer/adhesive layer used to stick closely to the screen, and is arranged on the bottom plate The entire surface of the inside of part 21. When in use, the packaging film (i.e. the lower film 4, detailed below) is removed to expose the adhesive layer 3, and the curved screen protective film of the present utility model can be connected to the electronic product through the adhesive layer 3 after overlapping the base plate 21 with the curved screen. The curved screen fits perfectly.

And, in order to prevent the curved screen protective film of the present utility model from being stained with dirt and scratches before being used by the user, generally when leaving the factory, an outer film is pasted on both sides of the curved screen protective film of the present utility model. In the case where the novel curved screen protective film has a functional film 6, as shown in FIG. Film 4, the above-mentioned outer film (upper film 5 and lower film 4) are product packaging films, which can be torn off during use. The material of the outer film is preferably PET film.

In order to improve the integration of the curved screen protective film of the present utility model, in the above-mentioned high-temperature shaping process, each film is usually shaped at the same time, that is, as shown in Figure 3, the upper film 5, the functional film 6, the peripheral part 2, the bottom plate part 21, The adhesive layer 3 and the lower film 4 are shaped into a curved surface together, wherein the temperature range during high-temperature shaping is preferably between 150°C and 210°C, and the time for high-temperature shaping is preferably more than 2 hours.

In addition, in order to meet different screen requirements, at least one of the above screen protective films may be a curved surface. The utility model has the following results after testing:

(1) Impact test

Dropping 250g of metal vertically at a height of one meter will not cause any damage to the product. Hit the product with a hammer gravity, and the tempered glass area will shatter like a spider web, but the surface of the phone is intact;

(2) Visual inspection

After the protective film is bonded to the curved screen, under a 60W fluorescent lamp, when viewed from the front and at an angle of 45 degrees, the curved surface of the protective film is closely bonded to the curved surface of the touch screen, and the bonding is full, without bubbles and watermarks;

(3) Optical properties

The light transmittance test shows that the light transmittance reaches 95% to 99%.

In summary, compared with the prior art, the utility model has the advantages and beneficial effects of:

1. Using the combination of tempered glass part and peripheral part, the screen protective film can be completely attached to the curved screen, which overcomes the problem that the existing technology cannot be completely covered and attached.

2. By adopting an embedded structure in which the toughened glass part is covered by the peripheral part and the bottom plate part, the combination of the toughened glass part is tighter and the firmness is better.

3. By being provided with a functional film, it is possible to prevent the main film part from being stained with oil and fingerprints during use and to enhance the hardness of the protective film.

4. After the screen protective film is completely attached to the curved screen, there are no gaps and bubbles, which is more beautiful.

Four, the test proves that the utility model has better drop resistance performance.
