Description
Technical field
The present invention is a kind of blast integrated type polarizing film/optical film structure and manufacture method, especially refer to that a kind of blast integrated type polarizing film/optical film that utilizes nonlinear optics to design different dyes is coated at least one substrate, this blast integrated type polarizing film/optical film comprises absorption-type and two kinds of polarisation retes of reflection-type, wherein the reflection type polarizing film layer can produce the reflection source effect, and produces a blast integrated type polarizing film/optical film structure and a manufacturing method thereof that has functional characteristics such as reflection blast effect, high degree of polarization, high-transmittance, wide viewing angle and height contrast simultaneously concurrently.
Background technology
LCD mainly utilizes two line polarisations that light polarizing film produced to reach display effect.Its main light source is provided by backlight module, and generation light backlight produces the line polarisation after through first Polarizer; Along with the arrangement of liquid crystal molecule is reversed, reach and produce bright dark variation behind second Polarizer, reach display effect to beholder's intraocular again.
Light source is through after many layer material refractions, reflection and absorbing, reaching observer's intraocular has become less than 5% light intensity, the absorption of the dichromatism polaroid in the display and printing opacity are for influencing one of brightness main cause, and therefore strengthening the intensity of light source, increasing light transmission rate is one of display material circumstance.Increasing integral light-transmitting degree method at present is that (1) increases the incident light penetration effect; (2) increase the backlight module light source.First kind of effect main method is raising light polarizing film penetrance, or before incident light does not enter light polarizing film, changes the polarization of incident light attitude earlier, makes the polarization parallel of its incident light polarization state and light polarizing film, increases incident light and penetrates efficient.Iodine is that the penetrance of light polarizing film is 44% to 46% high-penetration degree at present, has reached the scope that is difficult to increase transmittance; Change incident light polarization state, make its mode that reaches the high-penetration light intensity with the light polarizing film polarization parallel, based on the brightness enhancement film such as reflective polaroid of applying DBEF (3M company) and cholesterol liquid crystal; Second kind for the incident light that increases backlight come source strength or directly when backlight with light polarizationization to reach 100% polarized light penetration effect.Comprehensive above-mentioned institute says that the contrast of display, visual angle and light transmittance are mainly light polarizing film to determine, the transmittance that increases light polarizing film then is the following important development of light polarizing film.
The light polarizing film type is mainly O type iodine polarizing film at present, and its major advantage is (1) high degree of polarization (99.9%) and (2) penetrability (44%-46%).Shortcoming has strong leakage optical activity with great visual angle for (1), and the view film of must arranging in pairs or groups reaches high contrast effect, and (2) weatherability is bad not strong with (3) engineering properties, needs outer pasting protective film to strengthen character; (4) can only be affixed on outside display outward.E type liquid crystal light polarizing film is at present novel light polarizing film, and the polarisation film body is mainly based on the absorbefacient disc-like liquid crystal of tool, and when light during by disc-like liquid crystal, the O polarized light will be absorbed and the E polarized light will pass through, and reach linear polarisation effect.The at present best optical effect of this type of light polarizing film is that degree of polarization is about 95%, the about 40%-44% of penetrability.The shortcoming of E type light polarizing film is that (1) degree of polarization and penetrability slightly dislike not enough to TFT-LCD, and (2) small angle can produce light leak.Advantage is (1) light and thin type light polarizing film (about 0.3-0.8 μ m), and (2) can make in display organization (cell), please refer to the characteristic comparison sheet of Fig. 1 for O type light polarizing film and E type light polarizing film.
Compared to iodine and E type light polarizing film, another main research field of application type light polarizing film is that dyestuff is a light polarizing film, and this type of light polarizing film mainly absorbs carrier based on dyestuff.The receptivity parameter that influences light polarizing film is (1) dye molecule bulk absorption coefficient, and (2) add dye strength and (3) light polarizing film thickness.Dyestuff is that (1) weatherability is stronger for the light polarizing film major advantage, and (2) coating method can be selected in variation, and as processing procedures such as spin coating, die coating and dip coatings, (3) can be in display display organization internal production.Dyestuff is that the shortcoming of light polarizing film is difficult for obtaining of (1) high absorbance log dyestuff, and (2) high degree of polarization needs high concentration dyestuff composition, and cost is higher, and (3) high thickness (about 3 μ m) will cause penetrability to descend, and the restriction dyestuff is the application of light polarizing film.
Brightness enhancement film mainly can be divided into two kinds of cholesterol liquid crystal reflection-type and DBEF multilayer film reflection-types.The optical element of cholesterol liquid crystal reflective polaroid, its cardinal principle is to utilize the left-handed stalling characteristic with right-circularly polarized light of cholesterol liquid crystal, the not polarization white light of one incident is isolated left and right sides rounding polarized light, wherein the circularly polarized light of phase derotation optical activity can be penetrated, the identical circularly polarized light that revolves optical activity then is reflected, through the rotatory polarization of secondary reflection, increase the light percent of pass again for passing through.Cooperate 1/4 wavelength phase shift films, the rotatory polarization that passes through will change into the line polarisation and enter light polarizing film again, and net result converts light source fully to can reach the effect of blast totally by the polarization state of polaroid.Reflection-type polarisation brightness enhancement film (DualBrightness enhancement Film; DBEF) principle mainly is to utilize two kinds of high low-index materials of difference to form multilayer film, utilize white light to see through multilayer film, two kinds of S light that the white light of not polarization are divided into the P light of the parallel plane of incidence and vertical incidence face, after the white light process reflection-type polarisation brightness enhancement film, the P ripple penetrates and the S wave reflection, penetrate after the S of boundary reflection ripple will transfer the P ripple to, this final purpose penetrates light polarizing film with most light sources, reaches the blast effect.
Please refer to the characteristic comparison sheet of Fig. 2 for reflection-type polarisation brightness enhancement film and cholesterol liquid crystal reflective polaroid, by among Fig. 2 as can be known, the brightening effect of present commercially available brightness enhancement film is about about 60%.Analyze the light penetration effect of integral display, after the non-polarization light source sees through brightness enhancement film, transfer polarized light to again by light polarizing film, whole optical analysis can be considered the analysis of multilayer light polarizing film.Learn that by the optical analysis of multilayer light polarizing film two-layer above light polarizing film though can increase a little degree of polarization and contrast, significantly reduces transmittance without the optical match storehouse.As DBEF collocation iodine is light polarizing film (degree of polarization=99.8%, penetrability=44%) is example, its light penetration effect is light sees through light polarizing film earlier again through brightness enhancement film a effect, put aside catoptrical secondary penetration effect, DBEF penetrates efficient about 44%, with iodine be light polarizing film this as after the 44%-46% penetration combination, whole penetration will be reduced to about 40%-41%.
With degree of polarization, the degree of polarization of iodine polarizing film own has been about about 99.5%, and then brightness enhancement film can be ignored the contribution of whole degree of polarization.Comprehensive above-mentioned institute says that the brightness enhancement film collocation blast usefulness that light polarizing film produced is real in reducing penetration earlier, utilizes catoptrical secondary penetration effect to increase its penetration again.Hence one can see that, and the optical effect coupling of multilayer film is bad, with loss light percent of pass, even if increase brightness enhancement film, also can't show the due very blast effect of brightness enhancement film.Following if carry out making in the cell, then at present commercially available brightness enhancement film thickness is all above 100mm (DBEF surpasses 100mm), this thickness will cause the driving voltage skew and the making difficulty of cell inside, and therefore the present commercially available light polarizing film of collocation all can only be made the cell outside.
No. the 4591512nd, present main flow iodine polarizing sheet such as U.S. Patent number " making the method (Method of making light polarizer) of Polarizer ", it is with polyvinyl alcohol (PVA) (polyvinylalcohol; PVA) be base material; after carrying out uniaxial extension; soak iodine (Iodine) and work as absorption factor; be made into light polarizing film; but character such as the mechanicalness of rete, weatherability, thermotolerance are bad; iodine polarizing film removes that this is external, and the upper and lower surface TAC film of need fitting is a diaphragm, therefore the about 200 μ m of thickness of iodine polarizing film at present.E type polaroid is as U.S. Pat 6,583,284, US6,563,640, US6,174,394, US 6,049,428, US 5,739, and 296 etc., its light polarizing film is made with the cloth of coating-type processing procedure, and the discoid dimeric molecule (supermolecular) of tool assimilation effect is coated substrate surface, finishes E type polaroid; Its light passes light polarizing film and waits, and its polarization state is just opposite with traditional O type light polarizing film, is the E light polarization.Another kind of cloth of coating-type O type polaroid is that dye-coating is formed light polarizing film in substrate surface, U.S. Pat 5,812,264, US 6,007,745, US 5,601,884 and US 5,743,9802 grades be the patent of dye-coating light polarizing film aspect.
The brightness enhancement film cardinal principle is that the visible light of polarization is not divided into two kinds of mutually perpendicular polarized lights, and a kind of polarized light is penetrated, and is inverted to parallel polarization after the another kind of polarized light that vertically penetrates polarization reflects, and secondary penetrates then.
Reflection-type polarisation brightness enhancement film is exposed in U.S. Pat 5828488, US6101032, US6124971 etc. in the prior art.In U.S. Pat 599243, US6016177, exposure cholesterol liquid crystal reflection-type such as US6025958 and Application No. US20040130672_A1 disclose full cloth of coating-type cholesterol liquid crystal reflection-type blast assembly, and the purpose of this patent is colour cast for a change only.
Comprehensive above-mentioned described learning, at present in LCD display, be responsible for producing polarisation light polarizing film partly itself the blast effect is not arranged, and brightening effect is provided by brightness enhancement film, and different system separately, with brightness enhancement film and the combination of light polarizing film collocation laminating type, be not combined into the light polarizing film of real overall efficiency mostly.
