Description

Flexible glass for folding screen and flexible glass folding screen

Technical Field

The utility model relates to a flexible glass for folding screen mainly relates to the technical field of electronic product touch-sensitive screen.

Background

With the continuous development of the touch screen technology of electronic products, the touch screen of a straight panel cannot meet the current situation, and the product development and application to the folding touch screen are started, the existing folding touch screen usually folds on the basis of a flat panel screen to obtain the folding effect, however, the folding touch screen is prone to having creases when being used for a long time, the viewing effect of the screen is affected, and the existing folding touch screen does not have a multi-layer strength layer to protect the strength of the folding touch screen.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a flexible glass and flexible glass folding screen for folding screen makes its difficult crease that appears in long-time use, and strengthens its intensity protection.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a flexible glass for folding screen, includes the glass main part, be provided with the inward concave type portion of being convenient for fold on the glass main part top surface, be provided with the filling layer in the concave type portion, the bottom surface of glass main part is provided with the AF rete, the thickness dimension of glass main part is 0.33-0.7mm, the thickness dimension of concave type portion the glass main part is 0.01-0.27mm, the unilateral face or the both sides face of glass main part are provided with the buffer layer.

Preferably, the height dimension from the bottom surface to the top surface of the concave part is 0.27-0.65mm, and the width dimension of the concave part is 0.8-10 mm.

Preferably, two sides of the bottom surface of the concave part are in a round angle shape.

Preferably, the filling layer is a composite material of PI and silica gel or a solidified liquid PI material, and the filling height is 0.1-0.5 mm.

Preferably, the thickness of the AF film layer is 0.01-0.4 mm.

Preferably, the buffer layer is uniformly coated on the glass main body by a silica gel material or a mixture of silica gel and a PI material.

Preferably, a PI film layer is disposed on the top surface of the glass main body except the concave portion.

The application also provides a flexible glass folding screen, which comprises the flexible glass.

According to the above technical scheme, the utility model provides a pair of flexible glass and flexible glass folding screen for folding screen, through be provided with concave type portion in glass main part, inwards fold through concave type portion, but a flat board among the non-prior art is directly folding, can make the direct stack of the non-two-layer glass main part thickness of thickness after folding, but the thickness according to glass main part, the thickness that is not more than two-layer glass main part after accomplishing folding is done to the thickness of the filling layer that combines the degree of depth of concave type portion and it in, so, be difficult for appearing the crease, regard as first layer intensity layer through the filling layer, the AF rete is as second layer intensity layer, the buffer layer is as third layer intensity layer, form multilayer intensity protection.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below.

Fig. 1 is a schematic structural view of the present invention;

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In this embodiment, as shown in fig. 1, the flexible glass for a foldable screen includes a glass main body 1, an inward concave portion 2 convenient for folding is disposed on a top surface of the glass main body 1, the concave portion 2 may be disposed at a middle position or a non-middle position of the glass main body 1, a filling layer 3 is disposed in the concave portion 2, an AF film layer 4 is disposed on a bottom surface of the glass main body 1, a thickness dimension of the glass main body 1 is 0.33-0.7mm, a thickness dimension of the glass main body 1 of the concave portion is 0.01-0.27mm, a height dimension from a bottom surface to a top surface of the concave portion 2 is 0.27-0.65mm, a width dimension is 0.8-10mm, two sides of the concave portion 2 may be set to be rounded, so as to facilitate smooth folding, a thickness dimension of the AF film layer 4 is 0.01-0.4mm, the filling layer 3 is formed by curing a liquid PI material or a composite material of PI and silica gel, its packing height is 0.1-0.5mm, and the filling layer can fill the height in the concave type portion according to actual need, makes the two-layer thickness of its folding back be not more than the thickness of two-layer glass main part fifty percent discount, can also effectually carry out the protection of intensity to concave type portion, makes it difficult crease that appears of fifty percent discount repeatedly, the unilateral or both sides face of glass main part 1 is provided with buffer layer 5, and buffer layer 5 can further protect glass main part 1, and even coating is on glass main part after buffer layer 5 is mixed by silica gel material or silica gel and PI material.

Except the concave part 2, the top surface of the glass main body 1 is provided with a PI film layer 6, and the PI film layer 6 can be used as a fourth strength layer to further protect the top surface of the glass main body 1.
