CN203666036U - Tempered glass protective film for touch screen - Google Patents

The utility model discloses a tempered glass protective film for a touch screen. The tempered glass protective film comprises a tempered glass main body, wherein the thickness of the tempered glass main body is 0.1-0.4 mm; holes or openings are formed in the positions, opposite to a key and a listening hole on the touch screen, of the main body; an AF/AR layer is plated on the front side of the main body; 1-2 lightproof ink layers are printed on the back surface of the main body; a layer of A/B glue is further bonded, wherein A is optical cement, and B is silica gel. The edge of the main body is a 2D plane or a 2.5D arc edge. Compared with the mainstream PET protective films on the market, the tempered glass protective film for the touch screen has the advantages of scrape prevention, wear resistance, bubble prevention, glare prevention, fingerprint prevention, dirt resistance, easiness in cleanness, high temperature resistance, high touch sensitivity and smoothness in touch feel; the frame is clear so as to improve the visual effect; the frame light transmittance is high up to 95%, so that eyes are difficult to feel fatigue after long-time use, and the vision is preferably protected; the impact can be effectively relieved to prevent the screen from being smashed.

Touch-screen safety glass diaphragm

Technical field

The utility model belongs to touch-screen field, relates in particular to the touch-screen safety glass diaphragm on various device.

Background technology

Along with the develop rapidly of electronic technology, various touch-screen equipments are very universal.Touch screen is applied every field, makes the demand of touch-screen safety glass diaphragm increasing.Touch screen diaphragm is in the market mainly PET material, and non-refractory, not scratch resistant, easy to foaming, printing opacity definition is poor, touch feeling is not smooth, frangible screen etc. while being subject to external impacts, causes PET diaphragm can not really play the effect of protection touch screen.CN201220324619.4 discloses a kind of Multi-function armoured glass diaphragm, comprises the not reflective safety glass layer of a thin type, and the one side of safety glass layer scribbles glue.

Utility model content

The purpose of this utility model is to provide a kind of novel touch-screen safety glass diaphragm, reaches high temperature resistant, scratch resistant, non-foaming, printing opacity definition is good, touch feeling is smooth, effectively slow down the effect of impact.

To achieve these goals; touch-screen safety glass diaphragm of the present utility model; comprise safety glass main body; safety glass thickness is 0.1～0.4mm, the button on the corresponding touch screen of main body with listen hole site to be provided with perforate or opening, main body front is coated with AF/AR layer; main body back up has the ink layer of 1～2 layer of shading; one deck A/B glue of fitting again, A is optical cement, B is silica gel.Body rim is 2D plane or 2.5D arc limit.2.5D arc limit refers to that product edge has down hypotenuse, and through the curved shape of polishing back edge, more smooth, there is third dimension, can improve visual effect.

Body rim also can be 2D plane and does not do polishing, and 2D plane refers to that product edge do not do the processing of falling hypotenuse and not polishing, only does safe chamfered, and product surface is plane effect.

The positive vacuum coating of main body, sputter AF/AR or machinery coating hardened coating AF/AR layer, AF-is anti-fingerprint film, can effectively reduce fingerprint and the dirty generation at glass surface; AR-is high antireflective film thoroughly, can improve the light transmittance of glass and the reflectivity of attenuating glass.The main body back side is fitted with A/B glue-line (being that A is that optical cement, B are silica gel), is convenient to effectively fit together completely with touch screen, has to extenuate to impact and explosion-proof effect.Ink layer can print multiple color or various pattern, produces aesthetic feeling.

The utility model product is compared the PET diaphragm of main flow on market, has following advantage: scratch resistant, wear-resisting; Anti-bubble, anti-dazzle, anti-fingerprint, stain resistance, easy to clean, high temperature resistant; Sense of touch is highly sensitive, touch feeling is smooth; Picture is clear, raising visual effect; Picture light transmittance, up to 95%, is used eyes indefatigability for a long time, better vision protection; Effectively slow down impact, prevent broken screen.
