Abstract
The invention discloses a hard protective thin film comprising a transparent substrate, protective coating layers are arranged on the surfaces of the transparent substrate, particles are arranged in the protective coating layers and distributed on the surfaces of the transparent substrate, the geometric size of the particles which is perpendicular to the direction of each surface of the transparent substrate is larger than the thickness of each protective coating layer after the film formation; the hard protective thin film has the advantages that the particles are arranged in the protective coating layers, the geometric size of the particles which is perpendicular to the direction of each surface of the transparent substrate is larger than the thickness of each protective coating layer after the film formation, thereby forming concave and convex surfaces between the parts which are exposed out of the protective coating layers and the surfaces of the protective coating layers, easily removing entered air and moisture, preventing the occurrence of bubbles and significantly improving the protective capability of the thin film; polymer-based antistatic agents without dissolution are arranged in the protective coating layers, thereby allowing the protective thin film to have good antistatic capability; the protective coating layers are arranged on the two surfaces of the transparent substrate, and any surface can be attached on a liquid crystal panel by absorption, thereby allowing the operation to be more convenient.
Description
Technical field

Background technology
In recent years along with the fast development of liquid crystal indicator and its widespread use in mobile communication equipment demonstration, laptop computer displays, desktop computer display and large scale liquid crystal TV; requirement to the protective film of display device is also more and more higher; mainly concentrate on and alleviate injury, prevent destruction that moisture causes and the generation that prevents static.
The existing rigid protective film that is applied to liquid crystal indicator mostly is the protective film that adopts application pattern production and have the single face overlay.Fig. 5 is the structural representation of the rigid protective film produced of traditional employing application pattern, and this rigid protective film mainly comprises transparency carrier 10, last overlay 20.The rigid protective film that traditional employing application pattern is produced mainly relies on overlay protection, yet the protective capability of this rigid protective film is very limited, easily produce air-gap during with the absorption of liquid crystal panel in the liquid crystal indicator that is contacted, and be difficult for getting rid of the air that exists, thereby produce bubble; When running into moisture, also be not easy to get rid of the moisture between protective film and the liquid crystal panel, and when peeling off protective film, damage liquid crystal panel because of there being friction; Be subject to the influence of static when in addition, this rigid protective film is applied in the liquid crystal indicator.
Summary of the invention
Technical matters to be solved by this invention provides and a kind ofly can effectively alleviate damage, easily gets rid of the rigid protective film of the air that enters and moisture and uses the liquid crystal indicator of this rigid protective film.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of rigid protective film; it comprises transparency carrier; at least one surface of described transparency carrier is provided with protective finish; be provided with particle in the described protective finish; described distribution of particles on the surface of described transparency carrier, described particle perpendicular to the physical dimension of described transparency carrier surface direction greater than the film forming of described protective finish after thickness.
Described transparency carrier is that 1.4～1.75 optically transparent material is made by refractive index, described optically transparent material is PET (Polyethylene Terephthalate, polyethylene terephthalate), PC (Polycarbonate, polycarbonate) any and among the PE (Polyethylene, tygon).
Described particle be shaped as sphere or elliposoidal.
Be provided with antistatic agent in the described protective finish.
Described antistatic agent is a kind of antistatic agent of polymer electrolyte of not stripping.
Described protective finish be arranged on the surface of described transparency carrier or two surfaces on.
A kind of liquid crystal indicator; this device comprises and is used for the luminous light source assembly; liquid crystal panel assembly and rigid protective film; described rigid protective film comprises transparency carrier; at least one surface of described transparency carrier is provided with protective finish; be provided with particle in the described protective finish; described distribution of particles is on the surface of described transparency carrier; the part that described particle is exposed to described protective finish contacts with described liquid crystal panel assembly, described particle perpendicular to the physical dimension of described transparency carrier surface direction greater than the film forming of described protective finish after thickness.
Compared with prior art, the invention has the advantages that and be provided with particle in the protective finish, and particle perpendicular to the physical dimension of transparency carrier surface direction greater than the film forming of protective finish after thickness, make male and fomale(M﹠F) of formation between the surface expose part protective finish outside and protective finish, convex portions (particle is exposed to the part of protective finish) contacts with liquid crystal panel, the gap that makes a perforation of formation between protective finish and the liquid crystal panel, not only reduced the contact area of rigid protective film of the present invention and liquid crystal panel, and easily the air and the moisture that enter are got rid of, thereby prevented the generation of bubble, simultaneously alleviate the damage that when peeling off protective film liquid crystal panel is caused effectively, thereby made the protective capability of protective film be significantly improved; Be provided with a kind of antistatic agent of polymer electrolyte of not stripping in the protective finish, make this rigid protective film have good antistatic effect; On two surfaces of transparency carrier, protective finish is set, arbitrary face can be adsorbed on the liquid crystal panel, make that operation is more convenient.
