Stress concentration caused by curvature transition between 108 and the second side face 110 is too big can promote the resistance of glass matrix 10
Ability.The arc radius r2 of second curved portion 112 be 0.5-10mm, the corresponding circle of circular arc of second curved portion 112
Heart angle θ 2 is 15-60 °.
As shown in Figure 2, the decorative layer 20 is arranged on the inner surface 101 of glass matrix 10.The decorative layer 20 wraps
Include the first ink layer 21,22 and second ink layer 23 of label layer.
First ink layer 21 covers 107 and first flat part 103 of the first flat bottoms.In the production process, may be used
21 whole face of the first ink layer is arranged on inner surface 101 by way of printing, then logical overetched mode is removed and is formed in
Ink in first side portion 109, and the leaving a blank in first side portion 109.First ink layer 21 can play decoration with
And block the effect of glass cover-plate internal component.First ink layer 21 can form lamination by way of repeatedly printing.
The label layer 22 covers the first ink layer 21 and the first side portion 109 in the first flat bottoms 107.For just
In making, the precision that label layer 22 is formed is reduced, label layer 22 also can be extended over partly to first on the first flat part 103
Ink layer 21.22 and first ink layer 21 of label layer has different colours or texture difference, thus in 102 side of outer surface
When observing at label layer 22, label layer 22 is easily visually noticeable.In the embodiment with the first curved portion 111, institute
It states label layer 22 while covers first curved portion 111.Label layer 22 can be film plating layer, can also be and the first ink layer
The ink layer of 21 different colours.When label layer 22 is ink layer, if during h1≤0.25mm, the mode shape of silk-screen may be used
Into if during h1 ＞ 0.25mm, the modes such as bat printing or spraying may be used and formed.
Second ink layer 23 covers the label layer 22.Second ink layer 23 is used to protect label layer 22.Some realities
It applies in example, the second ink layer 23 can continue to extend toward the direction of the first flat part 103, to cover the first flat part 103 simultaneously
On first ink layer 21.Second ink layer 23 may be used the mode repeatedly printed and form lamination.
The present invention also provides a kind of electronic devices, know including the glass cover-plate in above-mentioned any one embodiment and fingerprint
Other module, the fingerprint recognition module are at least partially received in first recessed portion 105.Due to the shape on glass cover-plate
Into corresponding recessed portion so that the distance between fingerprint recognition module and finger reduces, and can ensure the sensitivity of fingerprint recognition；And glass
The thickness of the other parts of glass cover board can be relatively large, thus can ensure that the integral strength of glass cover-plate meets the requirements.In addition,
Label layer is provided in the side surface part of recessed portion, can cause fingerprint identification area domain that there is more obvious visual identity degree.
The present invention also provides a kind of production methods of glass cover-plate, include the following steps：
Glass matrix is provided, the glass matrix has opposite the inner surface and the outer surface.In electronic device is applied to
When, the inner surface of the glass matrix is towards inside electronic device, and the outer surface of glass matrix is towards the outside of electronic device.
Groove is respectively formed in the inner surface and the outer surface of glass matrix so that the inner surface includes the first flat part
And first recessed portion, first recessed portion include the first flat bottoms and cricoid first side portion, the first side portion
One end connect first flat bottoms, the other end in the first side portion connects first flat part；And cause institute
It states outer surface and includes the second flat part and the second recessed portion, second recessed portion includes the second flat bottoms and cricoid second
Side surface part, one end of the second side face connect second flat bottoms, described in the other end of the second side face connects
Second flat part.

The profile of first recessed portion is identical.The position of first recessed portion and the position of the second recessed portion are in correspondence with each other.First recessed portion
Size and the size of the second recessed portion can be identical or different.First recessed portion can lead to overetched mode and be formed in glass base
The inner surface of body.Second recessed portion can lead to the outer surface that overetched mode is formed in glass matrix.
In one embodiment, the position of the first flat bottoms and the second flat bottoms, size, shape are consistent.
Then, the first ink layer is formed on the internal surface.Then, then using e.g. laser-induced thermal etching either expose
The modes such as development remove the first ink layer in first side portion, and it is still blank to make first side portion.
Then, label layer is formed on the first ink layer in the first flat bottoms and first side portion.Mark
Layer can be the film plating layer with various textures.Label layer can also be the ink layer with the first ink layer different colours, when
When the depth of one recessed portion is less than or equal to 0.25mm, the mode that silk-screen may be used forms label layer；When the depth of the first recessed portion
When degree is more than 0.25mm, the modes such as bat printing or spraying may be used and form label layer.The difficulty and essence formed to reduce label layer
Degree, label layer can extend over the first ink layer on the first flat part.
Finally, the second ink layer is formed in label layer.The material of second ink layer can be with the material of the first ink layer
It is identical or different.Second ink layer can extend beyond label layer, and cover simultaneously on the first flat part described
One ink layer.
In some embodiments, first recessed portion, which further includes, is connected between the first flat bottoms and first side portion
First curved portion, the label layer cover first curved portion simultaneously；Second recessed portion further includes that be connected to second flat
The second curved portion between bottom and the second side face.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
