Ultrathin flexible glass and flexible glass bidirectional folding screen

Abstract

The invention discloses ultrathin flexible glass and a flexible glass bidirectional folding screen. ultrathin The flexible glass comprises a glass body, a downward first concave part is arranged on the upper surface of the glass body, an upward second concave part is arranged on the lower surface of the glass body, and filling layers are arranged in the first concave part and the second concave part. a folding part is formed between the first concave part and the second concave part on the glass body, and PI film layers are arranged on the upper surface and the lower surface of the glass body.The glass has the beneficial effects that the glass body is folded upwards or downwards, the sum of the thicknesses of the folded double-layer folding part and the double-layer filling layer is not larger than the sum of the thicknesses of the two layers of glass bodies, it is guaranteed that the folding part is not prone to crease, meanwhile, the filling layer has the effect of protecting the folding part, and supporting is provided for the folding part; bidirectional free folding of the glass body is achieved; and meanwhile, the PI film layer, the strength layer, the AF film layer and the buffer layer form multi-layer strength protection on the glass body.

Description

technical field [0001] The invention relates to the technical field of electronic display touch screens, in particular to an ultra-thin flexible glass and a bidirectional folding screen of the flexible glass. Background technique [0002] With the continuous development of the touch screen technology of electronic products, the straight touch screen can no longer be satisfied with the status quo, and the product development and application of the folding touch screen has begun. The existing folding touch screen is usually folded in half on the basis of the flat screen to obtain its folding effect. However, if it is used for a long time, creases will inevitably appear, which will affect the viewing effect of the screen, and the current folding touch screen does not have multi-layer strength layers to protect it. At the same time, the existing glass folding screens are all implemented by rotating shafts, which have complex structures, high manufacturing costs, and great diffic...

[0002]With the continuous development of the touch screen technology of electronic products, the straight touch screen can no longer be satisfied with the status quo, and the development and application of folding touch screen products have begun. Usually, the folding effect is obtained by folding in half on the basis of the flat screen. However, if it is used for a long time, creases will inevitably appear, which will affect the viewing effect of the screen, and the current folding touch screen does not have multi-layer strength layers to protect it. strength of protection

At the same time, the existing glass folding screens are all realized by rotating shafts, the structure is complex, the manufacturing cost is high, and the manufacturing is difficult. Moreover, the current folding screens are all one-way folding screens, which cannot realize two-way folding
