Description
Technical field
The present invention relates to a kind of automobile-used electronic display manufacturing technologies, in particular to a kind of to have the function of that AG+AR+AF is aobvious
The manufacturing method and diaphragm forming die of display screen.
Background technique
With the continuous development of technology, touch screen or windows be protected panel are widely applied；Such as mobile phone, palm electricity
Brain, automatic navigator, laptop, the ATM of financial circles, automatic card dispenser and the self-help registration terminal of hospital
Equal electronic products.Various windows be protected screens also proposed special optical requirement to the performance of plated film, such as existing protection panels
It is some special to make it have after the re-surface generally carried out using the substrate surfaces such as some glass, PMMA, PC, PMMA+PC
Effect.There is high transparency and low reflection with anti-dazzle effect, anti reflection glass including anti-glare glass vision panel protection screen
Effect and anti-fingerprint glass have the effect of anti-fingerprint, resist it is dirty.Present trend is to have both above-mentioned three proofings effect
Protection screen, the i.e. display screen with AG+AR+AF optical function have been more and more widely used.It applies in the safety such as such as automobile
The PMMA+PC diaphragm that generallys use in more demanding equipment is made, and this kind of protective film can be adopted directly from the market
Purchase is customized by specialized factory, and uses mature IML technology by three proofings functional membrane in form shell injection moulding process
Diaphragm and shell are formed into one.Before diaphragm and form shell form one, need first to heat and soften diaphragm, high pressure at
It type and cuts out, finally, diaphragm is placed in the injection mold of shell, in shell injection molding process, diaphragm is integrally formed in
On shell.Since the diaphragm after heating and softening has plastic deformation in forming process, lead to have the diaphragm of three proofings function saturating
The decline of light rate, haze value increase influence visual effect.For this reason, it may be necessary to improve.
Summary of the invention
The first object of the present invention is that window region light transmittance declines not in type-approval process for diaphragm in the prior art
Foot, provides a kind of manufacturing method with AG+AR+AF function display screen, is added by the subregion that heat-insulated web plate forms dual temperature control
Thermal effect, it is ensured that while deformed area reaches plastic deformation temperatures, window region be lower than deformed area desired temperature, to avoid or
Reduce window region deformation, eliminates or reduce window region light transmittance decline hidden danger, it is ensured that translucent effect.Second purpose of the invention is to mention
For a kind of diaphragm forming die, in diaphragm thermal histories, the window region and deformed area of diaphragm have the temperature difference of setting value, with
Ensure in diaphragm forming process and molding rear hatch area light transmittance is held essentially constant.
To realize that the first purpose, the present invention adopt the following technical scheme that.
A kind of manufacturing method with AG+AR+AF function display screen, including diaphragm is by thermal softening, diaphragm sizing and shell
The step of injection molding, and diaphragm and shell are formed by one by shell injection molding；Wherein, the step of diaphragm is by thermal softening
In, by the heat-insulated web plate being arranged between diaphragm and heating device, make the window region and shell combination of edge in the middle part of diaphragm
Deformed area is in different heated environments, to form the partition heating effect in two kinds of different temperatures regions, and reaches in deformed area and sets
When determining temperature, the temperature and deformed area temperature of window region have the temperature difference of setting value.
Using the method for the present invention of preceding solution, due to being heated in softening process in diaphragm, by being arranged in diaphragm

There is heat-insulated web plate, heat-insulated web plate is used to block the window region formation of diaphragm.
Using this mold of preceding solution, using being partially obstructed to radiant heat for web plate, make blocked area by
The received heat that heat is less than unshielding area makes the window region temperature in the middle part of the diaphragm being blocked to form partition heating effect
Lower than the temperature in edge deformation area, with when deformed area temperature reaches plastic deformation temperatures requirement, window region temperature is lower than plasticity
Deformation temperature, so in type-approval process, plastic deformation only is generated in deformed area, and window region seldom deforms or indeformable, really
It protects the decline of window region light transmittance seldom or does not decline.
Preferably, the upper mold is equipped with high pressure stomata, and in molding state, the diaphragm of high pressure stomata and lower die is formed
Die cavity connection.To make its deformed area generate plastic deformation by gas urges diaphragm, membrane surface is intact, further really
The light transmittance for protecting window region does not decline.
Preferably, the heating device is ceramic heating device.To utilize existing ceramic heat technology, temperature is relatively
It is low and the characteristics of convenient for control, avoid the occurrence of superheating phenomenon, it is ensured that heating process safety, temperature control are reliable.
Preferably, the film fixing structure includes at least two positioning pins, diaphragm support frame and diaphragm press box；Positioning pin
It is fixedly connected on diaphragm support frame, diaphragm support frame upper surface constitutes diaphragm support face, and diaphragm support frame is enclosed in described fixed
Pattern plate periphery, positioning pin are used to be threaded through the positioning hole of diaphragm；The diaphragm press box is for being pressed in the diaphragm.It is closing
After mould, diaphragm is fixed by press box and support frame by upper mold by the frame region for being located at deformed area periphery, positioning pin
Ensure that window zone position is accurate, it is ensured that shaping area relative position and shape are accurate, cut mold excision deformed area by carrying after molding
External redundance.Its structure is simple, reliable product quality.
It is further preferred that the heat-insulated web plate is fixedly connected on the diaphragm press box, heat-insulated web plate is by extension
