Description
Technical Field
The invention relates to the technical field of flat panel display, in particular to a glass cover plate, a preparation method and application thereof.
Background
As is known, with the continuous forward development of display technology, the flat panel display has not been able to fully meet the market demand. In 2019 world mobile communication Major (MWC), the folding display technology has begun to appear on the market along with the high-key appearance of various brands of folding mobile phones.
It is obvious that the greatest advantage of the folding display is that the displayable area is large when it is unfolded, and it does not require too much storage space when it is folded, and thus the market demand for it is strong. This is because as the degree of intellectualization of the mobile phone is higher and higher, there are more and more APPs that can be operated in the mobile phone, and correspondingly, the area of the displayable screen area that is needed needs to be further increased to accommodate richer and richer display contents, and the increase of the displayable area means the increase of the storage area, obviously, the storage area of the mobile phone cannot be increased without limit, and the contradiction between the two cannot be reconciled, so that the displayable area will have a threshold limit, but with the appearance of the foldable display panel, the contradiction can be perfectly solved. Moreover, the foldable OLED display panel has the advantages of all solid state, light weight, active light emitting, high image quality, low power consumption and the like, and can be used for transparent, scroll, folding, curved surface and the like to break through the traditional screen form.
The folding screen mobile phone which is developed at present is limited by materials and structures and only has two folding forms of outer folding and inner folding. The design structure of the glass cover plate arranged on the display panel can only be designed and fixed according to a single inward-turning or outward-turning form, so that the inward-turning or outward-turning arrangement of the display panel is determined.
In order to better improve the user's use diversity and flexibility, and meet the folding requirements or display requirements of different occasions, it is necessary to develop a foldable display panel that can simultaneously meet the requirement of folding inside and folding outside. The improvement of the folding function can inevitably lead to the fact that the intelligent terminal using the folding function as a display screen has wider use space.

Detailed Description
The technical scheme of the glass cover plate, the preparation method and the application thereof according to the present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, one embodiment of the present invention provides a glass cover plate including a first cover plate 10 and a second cover plate 20.
Wherein the first cover plate 10 is continuously provided with a projection 12, and one side end thereof is provided with a first catch 14. The structure of the second cover plate 20 is arranged corresponding to the structure of the first cover plate 10 so that the two can be combined together. Wherein the second cover plate 20 is continuously provided with a groove 22, and the other end thereof is provided with a second retaining column 24.
In the present embodiment, the protrusion 12 is in the shape of a trapezoid, the height of the protrusion surface is about 4 μm, and the distance from the top surface to the bottom surface of the first glass cover plate 10 is about 26 μm. It should be clear that the shape and height values of the protrusions 12 given above are only illustrative and not limiting, and the specific values can be determined according to actual needs.
Further, according to still another embodiment of the present invention, there is provided a method for manufacturing the glass cover plate, including the steps of:
step S1, providing the first glass cover plate 10 and the second glass cover plate 20, and performing micro-polishing and cleaning on the first glass cover plate 10 and the second glass cover plate 20 to ensure that the edge joint of the first structure protrusion 12 and the second structure groove 22 combined with each other has no particles and no flaws;
step S2, performing vacuum bonding on the first glass cover plate 10 and the second glass cover plate 20 to form the glass cover plate, wherein the completed drawing is shown in fig. 2.
As shown in fig. 2, due to the structural arrangement between the first glass cover plate 10 and the second glass cover plate 20, the protrusion 12 of the first glass cover plate 10 is received in the groove 22 of the second glass cover plate 20, so that the joint between the two forms a staggered space shape of saw teeth, and the first bumping post 14 and the second bumping post 24 respectively close the staggered space shape of saw teeth at two side ends.
It should be clear here that the first cover plate 10 and the second cover plate 20 are, though combined together, and due to the arrangement of the first retaining column 14 and the second retaining column 24, are integrated. However, at the position where the protrusion 12 is combined with the groove 22, it is clearly seen that the surfaces are not attached to each other, but a space gap of a space 30 exists, and the space 30 is provided with a vacuum. Wherein the gap width of this space gap may be in the range of 1 to 10 μm, as shown in fig. 2, which is 2 μm, but is not limited thereto.
The glass cover plate adopts a novel assembly structure, and the first glass cover plate and the second glass cover plate which are included in the glass cover plate adopt mutually corresponding matching structures, so that the joint of the first glass cover plate and the second glass cover plate after being combined is in a zigzag space shape which is staggered up and down, and the gap space is in vacuum arrangement. The adoption of the structure of the space at the interval of the joint can ensure the simultaneous inward bending and outward bending operation and prevent the horizontal and vertical slippage caused by the bending between the upper and lower glass cover plates because of the zigzag structure staggered up and down.
Furthermore, the existence of the space between the joints is beneficial to release the physical deformation of the glass cover plate during bending, and the adjacent sawtooth shapes can support and push each other, so that the glass cover plate cannot be cracked (crack) during bending.
Further, referring to fig. 3, another embodiment of the present invention provides a display screen, which includes the Cover Glass 100, the display Panel 200 and the middle Frame 300, which are sequentially disposed.
Further, another embodiment of the present invention is to provide a smart terminal including the display screen related to the present invention, wherein the smart terminal includes, but is not limited to, a smart phone, a smart tablet, an electronic book, a computer, and the like.
In the application of the display screen, the cover plate is made of glass instead of PI (polyimide) material, so that the surface hardness of the display screen can be relatively improved.
The technical scope of the present invention is not limited to the contents described in the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and these changes and modifications should fall within the scope of the present invention.
