Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
In the prior art, it carries out hot bending to glass to be faced with during hot bending, since glass heat-transfer rate is caused slowly
Glass fragmentation faced caused by glass internal/external heating is uneven, declines product yield, therefore very high to equipment precision requirement, while energy consumption
Higher problem.
The production method that core of the invention is to provide a kind of curved glass cover board, the flow chart of specific embodiment one
As shown in Figure 1, comprising:
Step S101: providing a glass substrate, and the glass substrate includes multiple the successively to arrange in a first direction
One region, the first area have region to be bent between the adjacent first area for binding display panel.
The thickness range of above-mentioned glass substrate is 0.3mm-3mm, including endpoint value, such as 0.30mm, 3.00mm or 1.85mm,
Glass substrate in this thickness section meets the thickness needs of hot bending.Certainly, in actual operation, due to demand difference, glass
The thickness of glass substrate can not also be in above-mentioned thickness section, as long as meeting hot bending needs.
Step S102: reduction processing is done to the region to be bent.
Above-mentioned reduction processing include do etching processing using fluorine-containing chemical reagent etching, or use CNN machining, or
Reduction processing is done to above-mentioned region to be curved using polishing process.
It is that low energy consumption using the advantage that glass is thinned in the mode that fluorine-containing chemical reagent etches, easy to operate, yield
It is high；It is that this method does not scratch glass using the advantage that glass is thinned in the mode of CNN cutting, glass surface finishes are splendid；Make
It is that equipment cost is low with the advantage that glass is thinned in polishing process, machining accuracy is high, in practical applications, can be according to practical need
The method for seeking selection reduction processing.
Step S103: the region to be bent after reduction processing is subjected to bend fixing, forms preset bending
Structure.
It is above-mentioned be thinned after the thickness range in region to be bent be 0.1mm-0.3mm, including endpoint value, as 0.10mm,
Region to be curved is thinned so far interval range, had both met the application by the way that region to be bent is thinned by 0.30mm or 0.21mm
Thickness, to reduce the purpose of the demand of energy consumption, reduction to equipment, in turn ensures in order to carry out bend fixing to glass substrate
Still there are enough structural strengths in region to be bent after being thinned.
Further, tempering processing can be carried out to the glass cover-plate for forming preset warp architecture, enhances its structure
Intensity facilitates subsequent install and use.
With reference to Figure 14, Figure 14 is a kind of top view of curved glass cover board provided in an embodiment of the present invention, curved shown in Figure 14
Bent glass cover-plate generation type is identical as above-mentioned embodiment, is carried out by the region to be bent 112 in glass substrate 11 thinned
After processing, bend fixing forms the warp architecture of specific structure.First area 111 includes the viewing area for fixed display panel
Domain K.
With reference to Figure 15, Figure 15 is a kind of side view of bending cover board for being fixed with display panel provided in an embodiment of the present invention
Scheme, in mode shown in Fig. 5, bending cover board is prepared again by aforesaid way by 11 bend fixing of glass substrate, structure
Above-described embodiment can be referred to, details are not described herein.Display panel 21 is fixed on the display area surface K of first area 111.
Display panel can be the display panels such as LCD panel or oled panel.
With reference to Figure 16, Figure 16 is the top view of another curved glass cover board provided in an embodiment of the present invention, shown in Figure 16
In mode, in order to enable curved glass cover board described in the embodiment of the present invention has preferable appearance effect after fixed display panel
Fruit, on that basi of the above embodiments, the production method further include that 11 surface of the glass substrate after bend fixing is formed
Ink layer 22, the ink layer 22 expose the display area K.When fixed display panel 21, display panel 21 and ink layer
22 are located at the same side surface of glass substrate 11, the surface be as inner surface, avoid ink layer 22 and display panel 21 by
To abrasion.
In order to avoid high temperature process steps damage ink layer 22, it is arranged after bend fixing and forms ink layer 22.Work as use
When tempering processing increases curved glass cover board intensity, equally, in order to avoid high temperature process steps damage ink layer 22, it is arranged in steel
Ink layer 22 is formed after change processing.
Ink layer can be formed in the region except the display area of above-mentioned first area, it is subsequent to be mounted not blocking
On the basis of display panel, play the role of reducing light reflection and decoration to above-mentioned curved glass cover board.
The production method of a kind of curved glass cover board provided by the present invention, by providing a glass substrate, the glass
Substrate includes multiple first areas successively arranged in a first direction, and the first area is adjacent for binding display panel
There is region to be bent between the first area；Reduction processing is done to the region to be bent；It will be after reduction processing
The region to be bent carries out bend fixing, forms preset warp architecture.The present invention is by treating bending region portion to be bent
Position carry out it is thinned, when reducing glass bending, soften glass required for energy, that is, energy consumption is reduced, simultaneously because glass is thick
Degree is thinned, and makes to be heated more evenly during glass bending, reduces uneven heating in heating process and cause glass fragmentation faced
Risk improves yields, simultaneously because heated, more evenly required softening degree is more easily reachd and controlled, and reduces pair
The requirement of equipment precision thereby reduces the cost of equipment investment.
On the basis of specific embodiment one, a kind of side that reduction processing is specifically done to the region to be bent is proposed
Formula, flow chart is as shown in Fig. 2, referred to as specific embodiment two, comprising:
Step S201: as shown in figure 3, provide a glass substrate 11, the glass substrate 11 include it is multiple in a first direction
On the first area 111 successively arranged, the first area 111 for binding display panel, the adjacent first area 111 it
Between have region 112 to be bent.
Step S202: as shown in Figure 4 and shown in Fig. 5, side wall 121 and 122 phase of bottom surface are formed in the region 112 to be bent
Mutually vertical groove 12.Wherein, Fig. 5 is the partial enlarged view of 12 position of Fig. 4 respective slot.
It should be noted that Fig. 4 and Fig. 5 further groove is only structural schematic diagram, do not represent groove actual size and
Size in glass substrate.
Step S203: as shown in fig. 6, the region 112 to be bent after reduction processing is carried out bend fixing, shape
At preset warp architecture.
By setting high-temperature process, so that region to be bent 112 bends to and needs curved-surface structure.During bending, by
In high-temperature process the glass material of 12 position of groove is melted, after solidifying and setting, region 112 and first area to be bent
111 form smooth curved surface interface.
Similarly, groove 12 is formed by reduction processing due to region 112 to be bent, there is relatively thin thickness, so that at this
Bending is relatively easy to, and can reduce bending process difficulty and yield rate.
On the basis of specific embodiment two, further the junction of bottom portion of groove and side wall is limited, is had
