Description

A kind of detachable flexible touch screen
Technical field
The present invention relates to touch screen technology field, and in particular to a kind of detachable flexible touch screen.
Background technology
Compared to conventional screen, flexible touch screen is with the obvious advantage, not only more frivolous in volume, also below original in power consumption There is device, contribute to the endurance of lifting means, while based on its characteristic flexible, that pliability is good, its robustness It is much higher than conventional screen, reduces the probability of equipment accidental injury.
But the flexible touch screen occurred in the market has many insufficient places in structure, such as touched in flexibility Touch and use glass cover-plate more improper on screen, so PET or PI materials are typically chosen, but these materials are compared on light transmittance Differ more compared with glass cover-plate;Flexible touch screen is affected by temperature larger, easily causes display distortion;Other touch-screen makes Easily it is damaged with a period of time back shroud, cut or slight crack occurs, because touch-screen is that an entirety can not be dismantled, so Whole touch-screen must must must all be changed, this can cause the waste in cost.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of detachable flexible touch screen, the flexible touch screen Using detachable structure, while there is very big improvement on screen is stable.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of detachable flexible touch screen, from inside to outside including substrate, electrode layer, FPC and cover plate, institute It is polyimide plate to state substrate, and is provided with interior vacuum heat resistant layer in the inner surface of substrate, and the electrode layer is covered in the outer of substrate Surface, and extension electrode is pulled out on electrode layer, the FPC is inserted into the extension electrode of electrode layer, the flexibility Wiring board is by PET film bottom plate and is compressed on the conductive metal mesh of PET film backplate surface and is made, and the cover plate is that polyamides is sub- Amine plate, and scribble light-transmissive film layer in the outer surface of cover plate;
The substrate, electrode layer and FPC bonding are in one, and the both sides of cover plate opposition are to interior edge Vertical Square To extension, extension is formed, the extension is connected with the edge movable of the substrate, electrode layer and FPC.
Further improvement is that the edge of the medial surface and substrate, electrode layer and FPC in the extension Some horizontal ripples are formed, and the both sides ripple on flexible connection face is engaged by etching processing on face.
Further improvement is that the making material of the interior vacuum heat resistant layer include organosilicon modified polyester acrylate, Pentaerythritol triacrylate, urethane acrylate, 2- hydroxy-2-methyl -1- phenyl -1- acetone, multi-walled carbon nanotube, three Aoxidize two arsenic and titanate coupling agent.
Further improvement is that the making material of the interior vacuum heat resistant layer includes organic-silicon-modified gather by weight percentage Ester acrylate 10-20%, pentaerythritol triacrylate 5-20%, urethane acrylate 25-40%, 2- hydroxyl -2- first Base -1- phenyl -1- acetone 5-15%, multi-walled carbon nanotube 1-5%, arsenic trioxide 1-10% and titanate coupling agent 5- 10%.
Further improvement is that the making material of the conductive metal mesh is selected from silver, copper, ruthenium-oxide, manganese oxide, oxidation One or more in zinc, cobalt oxide.
Further improvement is that the light-transmissive film layer is 0.10-0.15 μm of SiO by thickness2Film and thickness are 0.02- 0.05 μm of TiO2The composition of film.
The beneficial effects of the invention are as follows:
1) detachable structure is used, directly slides touch-screen cover plate, inhomogeneity can be changed as needed during use The cover plate of type, when cover plate is damaged, cover plate is directly changed, saves cost.
2) material of the metal grill as touch control layer is used, it was both limited without traditional ITO materials by rare element indium reserves The defects of processed, again without CNT electric conductivity it is bad the defects of, and its cost of material and can on folding endurance advantage it is bright It is aobvious.
3) touch-screen is provided with vacuum heat resistant layer in the inner side of substrate, when in use, has both reduced electrical equipment (shielding in display) The influence generated heat to touch-screen, ensures its touch sensitivity, reduces extraneous strong light or thermal source again and electrical equipment (is shielded) in display Infringement, add its service life.
4) outside of touch-screen is provided with light-transmissive film layer, increases the light transmittance of whole touch-screen, reduces reflective phenomenon.
