Description
Technical field
The present invention relates to technical field of touch control, more particularly to a kind of touching display screen and its glass cover-plate and production side
Method.
Background technique
Touching display screen generally includes the glass cover-plate for contacting with finger.Traditional glass cover-plate is that 2D glass is (pure
Flat glass, without cambered design), gradually appear 2.5D glass (centre is plane, and edge is cambered design) and 3D glass
Glass (whole to use cambered design).Glass cover-plate is developed from 2D glass to 3D glass, improves the whole vision of touching display screen
And feel, 3D glass cover-plate are needed through the multiple tracks processing procedure such as hot bending, equipment investment requires height, and yield is low, causes overall cost to occupy high
Under not, although and 2.5D glass can use lower-cost CNC (Computer Numerical Control, computer number
Word controls lathe) processing procedure is formed, but its whole vision and feel are not as good as 3D glass cover-plate.
Summary of the invention
Based on this, it is necessary to provide one kind with 3D visual effect and the lower touching display screen of cost of manufacture and its glass
Cover board and production method.
A kind of glass cover-plate, including glass body, the glass body include the first surface being oppositely arranged and the second table
Face connects the of the first surface and the side with the first surface and the vertically disposed side of the second surface
One tapered plane connects the cambered surface of the first surface and first tapered plane, and connects the second surface and the side
Second tapered plane in face；
Wherein, the glass body has visible area and is surrounded on the non-visible area domain of the visible area, the arc
The sideline that face is connect with the first surface is the first sideline, and the sideline that the cambered surface is connect with first tapered plane is second
Sideline, first sideline are located in the visible area.
Above-mentioned glass body is by the first tapered plane of setting, cambered surface and the second tapered plane, so that glass body group
After on touching display screen, visual effect and touch effect with 3D glass.Namely it is above-mentioned be in the nature 2.5D glass sheet
Body has the visual effect roughly the same with true 3D glass and touches effect, and above-mentioned glass body is vision 3D glass.On
Equipment cost can be greatly reduced and be reduced processing procedure work using relatively easy CNC cutting technique production by stating glass body
Sequence, to reduce production cost.

It applies in mode, only in the relatively long two sides (left and right sides) of glass body 100, is respectively formed the first tapered plane 140, cambered surface
150 and second tapered plane 160, not processed to the relatively short two sides (upper and lower two sides) of glass body 100,
I.e. there is no in the relatively short two sides (upper and lower two sides) of glass body 100, it is respectively formed the first tapered plane 140, cambered surface 150
And second tapered plane 160.CNC cutting is carried out with 3D effect, only upper and lower two relative in 100 4 side of glass body
Side carries out CNC cutting, can simplify processing technology.
It in other embodiments, can also be in glass body 100 especially when touching display screen can be displayed in full screen
Relatively short two sides (upper and lower two sides), be respectively formed the first tapered plane 140, cambered surface 150 and the second tapered plane 160, from
And make touching display screen that there is better 3D effect.Namely cambered surface 150 and the first tapered plane 140 are also set to second side 134
Between the first plane 110, the second tapered plane 160 is also set between second side 134 and the second plane 120.
Further, as shown in fig. 6, in the present embodiment, being also formed with rounded corner 170 in the end in the first sideline 152.
Setting rounded corner 170 can make glass cover-plate 12 whole more mellow and fuller, it appears that softer comfortable.Specifically, in present embodiment
In, the first sideline 152 extends to the corner of glass body 100, and rounded corner 170 is located at the corner of glass body 100.
As shown in Figures 1 and 2, ink layer 200 is set on second surface 120 and is located at non-visible area domain 100b.
