Abstract
The utility model provides a kind of four curved surfaces and is bonded diaphragm entirely, and it facilitates mould one-shot forming, and covering surface screen, guarantee screen can be applicable comprehensively with safer.It includes from top to bottom the upper protective film of sequentially superimposition, H/C, the first PET, OCA, the 2nd PET, layer of silica gel, mould release membrance, and four sides of the diaphragm being compounded to form are curved-surface structure.
Description
Technical field
The technical field of safeguard film for cellular phone is the utility model is related to, is specially that a kind of four curved surfaces are bonded diaphragm entirely.
Background technology
Mobile phone screen form development makes rapid progress, and largely occurs Curved screen currently on the market, in the technology of front end
Even more there are the curved surface of one side four or eight curve screens, although but four curved surfaces or eight Curved screens occurs in the market mobile phone one side
Curtain, but the manufacture of safeguard film for cellular phone temporarily can not upper screen demand, existing pad pasting is largely only capable of protecting screen
Center plane region or both sides curvature portion, due to the composite construction of existing safeguard film for cellular phone, it not adding during manufacture
Work goes out four curved surface diaphragms, for this reason, it may be necessary to research and develop a kind of membrane structure that can be applied to the manufacture of four curved surfaces.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of four curved surfaces is bonded diaphragm entirely, its facilitate mould once into
Type, and covering surface screen, guarantee screen can be applicable comprehensively with safer.
A kind of four curved surfaces are bonded diaphragm entirely, it is characterised in that：It includes from top to bottom the upper protective film of sequentially superimposition, H/
C, the first PET, OCA, the 2nd PET, layer of silica gel, mould release membrance, four sides of the diaphragm being compounded to form are curved-surface structure.
It is further characterized by：The transition of adjacent curved-surface structure is surface blending so that curved edges are wrapped up entirely, are protected
Stay screen arc aesthetic feeling；
The thickness of the upper protective film is 50 μm；
The H/C is specially hardened layer/protective layer, and its thickness is 2 μm~3 μm；
First PET, the 2nd PET are the PET of same thickness, and its thickness is specially 50 μm；
The OCA is the double faced adhesive tape for having optically transparent one layer special no base material, and its thickness is 8 μm~10 μm；
The thickness of the layer of silica gel is specially 20 μm~25 μm；
The thickness of the mould release membrance is specially 50 μm.
After structure of the present utility model, after seven-layer structure is compounded to form into integral membrane, synchronous punching press positioning hole is utilized
It is bent so as to carry out four and using profiling blank mould punching profile with the curved surface film of hardware dies processing and fabricating four of hot pressing radian
The volume production of surface protective film, it is covered comprehensively to screen, when mobile phone is by moment impact, can pass scattered power rapidly to entirely
Plane, effectively enhance mobile phone drop test performance., more can be true during drop test before mobile phone dispatches from the factory and consumer's use
Protect the explosion-proof type of mobile phone screen.
Brief description of the drawings
Fig. 1 is main view schematic diagram of the present utility model；
Fig. 2 is membrane structure simplified schematic diagram of the present utility model；
Title in figure corresponding to sequence number is as follows：
Curved-surface structure 1, surface blending 2.
Embodiment
A kind of four curved surfaces are bonded diaphragm entirely, see Fig. 1, Fig. 2：It includes from top to bottom the upper protective film of sequentially superimposition, H/
C, the first PET, OCA, the 2nd PET, layer of silica gel, mould release membrance, four sides of the diaphragm being compounded to form are curved-surface structure 1.
The transition of adjacent curved-surface structure is surface blending 2 so that screen curved edges are wrapped up entirely, and it is beautiful to retain screen arc
Sense；
The thickness of upper protective film is 50 μm；
H/C is specially hardened layer/protective layer, and its thickness is 2 μm~3 μm；
First PET, the 2nd PET are the PET of same thickness, and its thickness is specially 50 μm；
OCA is the double faced adhesive tape for having optically transparent one layer special no base material, and its thickness is 8 μm~10 μm；
The thickness of layer of silica gel is specially 20 μm~25 μm；
The thickness of mould release membrance is specially 50 μm.
After seven-layer structure is compounded to form into integral membrane, processed using the hardware dies of synchronous punching press positioning hole and hot pressing radian
Four curved surface films are made, and using profiling blank mould punching profile, so as to carry out the volume production of four curved surface diaphragms, it enters to screen
Row covering comprehensively, when mobile phone is by moment impact, can pass scattered power rapidly to whole plane, effectively enhance mobile phone and fall survey
Try performance.During drop test before mobile phone dispatches from the factory and consumer's use, the explosion-proof type of mobile phone screen more can ensure that.
Specific embodiment of the utility model is described in detail above, but content is only what the utility model was created
Preferred embodiment, it is impossible to be considered as the practical range for limiting the utility model creation.All created according to the utility model is applied
Equivalent change that scope is made all should be belonged to still within this patent covering scope with improving etc..
