Abstract
An optical adhesive film comprises an adhesive tape, a PET (polyester) coating film and a PET release film, wherein the adhesive tape is a 3M8187C adhesive tape, and the PET coating film is coated on the 3M8187C adhesive tape. The surface of the PET coating film coated on the 3M8187C adhesive tape is half cut by a flat-bed die cutting machine, so that the optical adhesive film is formed once. A tool with a 25-degree angle is internally straight and externally inclined, the height of the tool is 2.5mm, and the PET release film is coated on the optical adhesive film formed by means of die cutting. The optical adhesive film is formed once by the flat-bed die cutting machine, cut marks and bubbles during die cutting are avoided, optical and mechanical performances of a display are improved substantially, diffuse reflection of light can be decreased effectively, water streaks of a pressed screen are eliminated, the waterproof performance of the display is enhanced, and the service life of the display is prolonged. Moreover, the optical adhesive film is low in cost, easy in implementation and fine in implementation effect, and has extremely high practicability and wide market prospect.
Description
Technical field
The utility model relates to a kind of liquid crystal display technical field, especially relates to a kind of optics glued membrane.
Background technology
Optical cement is as the special adhesive that is used for glued transparent optical element.Have water white transparency, light transmission rate more than 90%, consolidation strength is good, can under room temperature or middle temperature, solidify, and characteristics such as cure shrinkage is little are arranged.The optical clear glued membrane is applicable to many transparent film substrate bondings on glass with special adhesive.Be widely used in the cementation of the LCD panel of mobile phone screen, computer screen, but when the optics glued membrane was carried out cross cutting, cutter seal and bubble appearred in laminate product frame easily with cover plate at present.
Summary of the invention
The utility model purpose provides a kind of optics glued membrane.Technical problems such as cutter seal, bubble appear easily to solve existing in prior technology laminate product frame.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: this optics glued membrane comprises that adhesive tape, PET cover inferior film, PET fractal film, and wherein adhesive tape is the 3M8187C adhesive tape, and it is multiple on the 3M8187C adhesive tape that said PET covers inferior film; And make its optics glued membrane once shaped through the hemisection from the good again inferior face of 3M8187C adhesive tape of flat cutting die cutter; Wherein cutting-tool angle is 25 °, and is interior straight tiltedly outer, knife up 2.5mm; Said PET fractal film is multiple on the optics glued membrane of shape by die-cutting.
The utility model is through flat cutting die cutter once shaped; Cutter seal and bubble can not appear during cross cutting; It has significantly promoted the optics and the mechanical property of indicating meter, can well reduce the diffuse-reflectance of light, the water wave phenomenon of eliminating the generation of screen pressurized, enhancing indicating meter water resistance, prolong display life.Nation's contrast gradient, outdoor readable property, resistance to vibration and anti-impact force of back indicating meter surely all obviously improves.And, with low cost, easy to implement, and implementation result is good.Have very strong practicality, market outlook are wide.
Description of drawings
Fig. 1 is the structure sectional view of the utility model.
Embodiment
Below through embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.
Fig. 1 is the structure sectional view of the utility model.Can know by Fig. 1; This optics glued membrane mainly by 3M8187C adhesive tape 1, PET cover inferior film 2, PET fractal film 3 is formed; Wherein PET covers that inferior film 2 is multiple then selects 25 ° of cutting-tool angles for use on 3M8187C adhesive tape 1, and is interior straight tiltedly outer; The flat cutting die cutter of knife up 2.5mm covers 2 of inferior films from the multiple good PET of 3M8187C adhesive tape 1 to be gone up hemisections and makes its optics glued membrane 4 once shapeds, on the optics glued membrane 4 of shape by die-cutting, gets final product PET fractal film 3 is multiple at last.
During use, directly the optics glued membrane is fitted between mobile phone or computer LCD drawing board and the sheet glass, it is bonded together securely, thereby overcome the indeterminable technical problem of prior art through rigging machine.
Claims (1)
