Abstract

The invention relates to a method for forming a mold belt pair roller (TTR) of a photosensitive resin layer surface microstructure, wherein the surface microstructure is formed by laminating a forming mold belt with anti-sticking and low surface energy and a photosensitive resin (such as UV glue) before curing, and the surface of the photosensitive resin layer is cured and loses fluidity before the photosensitive resin or the viscose enters a completely curing and forming UV lamp through a surface primarily curing UV lamp so as to avoid the stamped and formed microstructure from being dispersed or deformed, and finally the primarily cured photosensitive resin layer microstructure is completely cured by using the curing and forming UV lamp. The invention also relates to an optical film (optical film) produced according to said method.

The mould band pair roller wheel shaping method and the optical thin film of resin layer surface micro structure

Technical field

The present invention relates to a kind of mould band pair roller wheel shaping method and optical thin film of resin layer surface micro structure, relate in particular to a kind of mould band pair roller wheel shaping method of photo-sensitive resin surface micro-structure and the optical thin film that makes according to this method.

Background technology

Some LCD use brightness enhancement film increasing the light output briliancy of LCD in a large number, and make light output direction level off to quadrature or coaxial direction in liquid crystal display equipment screen.The general brightness enhancement film of using, the surface has microstructure, and its microstructure can comprise prism array, and the optical texture of this prism array can effectively increase the quantity of on-axis rays and reduce required energy of light source, the on-axis luminance of wanting with generation.Generally comprise brightness enhancement film in the backlight module in the LCD, this brightness enhancement film is positioned between diffusion sheet and panel of LCD.Backlight liquid crystal display also comprises light source such as cold-cathode fluorescence lamp (cold cathodefluorescent lamp; CCFL), light emitting diode (LED), micromolecule light emitting diode (MOLED) or polymer LED (PLED) or area source etc., the light of light source by light guide plate with the light direction of photoconduction to panel of LCD.Brightness enhancement film (or prismatic lens) (Brightnes s enhancement films; BEF) therefore the photoconduction that light guide plate can be sent can increase the brightness of panel of LCD to collimation direction (dwindling the dispersion angle of dispersing light source).In addition,, increase the light utilization rate, can use reflective polarizers (DBEF or CBEF) once more light to be done to reclaim and use to save electric power in order to improve the briliancy of LCD.The brightness that increases can make panel of LCD produce image clearly, also can reduce the loss of energy of light source.Prismatic lens in the LCD is used for graphoscope such as knee escope and computer screen, TV, video recorder, mobile communication element, portable element such as mobile phone and PDA, automobile, avionic display etc. in a large number.Prismatic lens is the optical thin film of a kind of light-permeable and tool microstructure, microstructure is made up of many prisms, utilize the total reflection and the refracting characteristic of prism inside to change direction of light, scattering and disappearing of restriction light to increase the loss of brightness and minimizing energy, relevant patent sees that international publication number is WO96/23649 number patented claim, and its optical texture is seen Fig. 1.Wherein, prismatic lens P1 up and down, P2 comprises a base film P3 and prism array such as P4, P5, P6, P7, P8, P9, P10, P11, P12 wherein, base film P3 and prism array tool one interface Pi.Each prism such as prism P4 have first prism facets Pa and second prism facets Pb, and the edge on the top on two planes interlocks and forms a summit, and its angle can be between 70-120 degree or 80-100 degree, and prism facets does not need to be defined, and only need incline towards each other.In addition, the thickness and the relation between prism height of base film are unimportant, but wish to cooperate with thinner base film the prism of definition, the angle of prism facets Pa and Pb and base film P3 can be 45 degree, but this angle is decided by the interval of face or the angle of summit.Prism P4, P5, P6, P7 and P8, P9, P10, P11, P12 form makes whole one-tenth an array.Optical element for example brightness enhancement film, angle limitations blooming or reflecting element etc. all is article that the base film surface has the Microstructure Optics design, and these microstructure major parts are made of a kind of sequence that replaces by spike (tips) He Goucao (grooves), for example the tool rule repeats and the spike and the ditch mortise of symmetry promptly form brightness enhancement film, other example comprises asymmetric spike and asymmetric ditch mortise, with the design different with size, direction or the spacing of ditch mortise of various spikes.Disclose in United States Patent (USP) No. 5771328 (Light directing filmhaving variable height structured surface and light directing articleconstructed therefrom) in addition, can eliminate optical coupled (wet-out) phenomenon by the small variation of prism peak height, in the hope of best light harvesting effect, make the audience can obtain under normal operation optimal brightness and all together the degree.Making of this prismatic lens is on the base film of a high penetration, and evenly photosensitive resin coating such as acrylic resin (acrylic resin) utilize the crosslinked volume production moulding of micro-nano imprint technology and ultraviolet light polymerization again.For most of backlight modules, can increase by 60% briliancy in putting a slice prism agreement that contracts a film or TV play to an actor or actress, but 2 prismatic lenses with under the vertical overlapping more the hoisting module briliancy reach 120% approximately, that is, reducing power consumption and prolonging battery under service time, can make the brightness of LCD screen increase by 2.2 times.

Previous U.S. publication application (US 2005/0134963 A1, Method for stackingsurface structured optical films) disclosed the technology of brightness enhancement film, its technology is evenly to be coated with one deck UV glue on a transparent base, is passing through rolling manufacturing process (Roll-to-Roll; RTR), the microstructure transfer printing on the metal running roller at the UV glue-line, is passed through UV lamp full solidification again with then on described transparent base.But owing to use the rolling manufacturing process when making these optical thin films, partly solidified UV glue easily is attached on each spike and ditch mortise of the more high or low contact angle of surface energy (contact angle) metal running roller, make it follow-up when continuous embossed, easily produce the microstructural defects on the optical thin film, or cause running roller to can't bear to use, this makes it range limited in utilization, and running roller involves great expense, in time, must renew, the manufacturing cost that heightens, and manifest its shortcoming.

In view of this, the present invention discloses a kind of UV glue-line surface micro-structure forming method, and the UV glue that its mould is difficult for being cured easily is attached to the surface, the rate that manufactures a finished product and the throughput rate of increase optical thin film under durable prerequisite.
