Description
Technical field
The present invention relates to a kind of protecting LCD screen glass, especially radioprotective low reflective liquid crystal screen protection and protect glass.
Background technology
Computer in order to protect liquid crystal display screen, waterproof and dustproof, on liquid crystal display screen, generally post protection glass.This post guarantor
Protect the liquid crystal display screen overall reflectivity in the sun of glass more than 12%, show that dark problem is most to solve liquid crystal display screen under sunlight
Use brightness enhancing display device brightness.Display uses when high brightness for a long time, and the life-span can reduce.Height in the environment of dim
Bright display is dazzling.
Electromagnetic radiation has certain harm to human body, also can reveal information, can produce electromagnetic interference, therefore to electronics simultaneously
The requirement of product anti-electromagnetic-radiation is more and more higher.And the ability of liquid crystal display screen anti-electromagnetic-radiation is more weak, common protection glass also cannot
Radiation-resisting functional is provided.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of radioprotective low to sunlight reflectance, reduction electromagnetic radiation low instead
Penetrating protecting LCD screen glass, concrete technical scheme is:
Glass is protected in radioprotective low reflective liquid crystal screen protection, and glass is provided with antireflection film with the upper surface of air contact, connects with liquid crystal display screen
The lower surface touched is sequentially provided with radioprotective coating and an OCA optical cement layer.
Stack gradually below a described OCA optical cement layer and be provided with polaroid, the 2nd OCA optical cement layer, the one 1/4 λ ripple
Plate, air layer, the 2nd 1/4 λ ripple plate, the 3rd OCA optical cement layer.
Described radioprotective coating is metal grill coating.
Described metal grill coating is monel grid coating.
Described glass is electro-conductive glass.
Antireflection film is the upper surface that the method by vacuum coating is plated in glass, reduces the reflection of glass.
Metal grill coating is to utilize vacuum coating technology to plate metal in glass back, and recycling gold-tinted lithographic techniques is entered
Row etching, forms the metal grill coating of anti-electromagnetic-radiation in glass back.Electromagnetic radiation is down to 20db by metal grill coating
Hereinafter, effectively prevent the leakage of information, reduce electromagnetic interference, the minimizing electromagnetic radiation injury to human body.
Screen reflection rate is effectively lowered in the use of antireflection film, metal grill coating and an OCA optical cement layer, and plays
Radiation-resistant effect.
By increasing polaroid, the 2nd OCA optical cement layer, the one 1/4 λ ripple plate, air layer, the 2nd 1/4 λ ripple plate and the 3rd
OCA optical cement layer lowers screen reflection rate further.
Utilize polaroid and 1/4 λ ripple plate to be integrated into rotatory polarization sheet, thus produce optically isolated effect, reduce air cavity anti-
Penetrate rate, and metal grill coating can solve the color fringe that polaroid photoelastic effect produces.The material of polaroid back layer is necessary
Being unipolarity material, the thin film such as the PET generally used has photoelasticity should, it is not possible to uses inside this coating structure.Polarisation
Sheet back layer needs the stressed cord using unipolarity material to avoid producing photoelastic effect, has the PET etc. of birefringence problem thin
Film all cannot.Therefore the unidirectional material of the 1/4 λ ripple plate following manufacturer production of employing:
TAC, Japan Supreme Being people's PC thin film, JSR ARTON, Zeonor, PMMA, Glass.
1/4 λ ripple plate and polaroid use vacuum patch technology, are fit together by OCA optical cement layer.Liquid crystal display screen and anti-spoke
Penetrate low reflective liquid crystal screen protection and protect the glass vacuum abutted technology of employing, fit together by OCA optical cement layer.OCA
(Optically Clear Adhesive) is for the extraordinary adhesive of cementing transparent optical element (such as camera lens etc.).Have colourless
Transparent, light transmission rate more than 90%, cementing strength good, can solidify under room temperature or middle temperature, and the spy such as have cure shrinkage little
Point.OCA optical cement is one of raw material of important touch screen.It is that optics acrylic glue is made without base material, then goes to the bottom upper
Layer, respectively one layer of release film of laminating, be a kind of Double-face adhesive rubber alloy band without matrix material.
Beneficial effects of the present invention:
Sunlight reflectance reduction to 4%, impact resistance ability improve 2.5 times, anti-electromagnetic-radiation, electromagnetic radiation is down to 20 db with
Under, 1000 hours rings of metal grill coating survey impedance rate of change less than 1.5%.
