Description
本發明係屬於一種膜結構，尤指一種光配位光學膜，其主要利用奈米核殼粒子的光催化特性，令此奈米核殼粒子受可見光的照射之後，讓每個奈米核殼粒子因為電子電洞對的產生而使表面帶有相同電性之電荷，使得分子可以均勻矩陣的排列在有機膠中，再以外加磁場，來控制奈米核殼粒子之間的距離，最後再以光或熱將膠固化，使奈米核殼粒子固定在塗佈層中，形成光配為光學膜。The invention belongs to a film structure, in particular to a photo-coordinating optical film, which mainly utilizes the photocatalytic property of the nano-core shell particles, so that the nano-core shell particles are irradiated by visible light, and then each nano-core shell particle is obtained. Because of the generation of electron hole pairs, the surface has the same electrical charge, so that the molecules can be evenly matrixed in the organic glue, and then the magnetic field is applied to control the distance between the nano-core particles, and finally The glue is cured by light or heat, and the nano core shell particles are fixed in the coating layer to form a photo-alignment as an optical film.
Flat Panel Display(FPD)顯示器本身無法主動發光，故需要背光來提供光源，因此光學膜在現今FPD顯示器產業中扮演著重要的角色。The Flat Panel Display (FPD) display itself does not actively emit light, so a backlight is required to provide the light source, so the optical film plays an important role in the current FPD display industry.
菱鏡技術為BEF(Brightness Enhancement Film)其主要在Polyester光學薄膜上塗佈UV樹酯，再利用預鑄微結構之滾輪轉印。其具有以下缺點：1.因柱狀透鏡結構，容易形成網紋(moire)。2.正視角時看是增亮，其實側視角時轉變為暗區而不具有增亮效果。The lens technology is BEF (Brightness Enhancement Film), which is mainly coated with UV resin on the Polyester optical film, and then transferred by the roller of the microstructure. It has the following disadvantages: 1. Due to the lenticular lens structure, it is easy to form a moire. 2. When viewing from a positive angle of view, it is brightened. In fact, the side angle is changed to a dark area without a brightening effect.
3M公司發展出一種反射式偏振光增亮膜DBEF(Dual Brightness Enhancement Film)，係運用多層膜技術，由將近千層具特殊雙折射率(Birefrigence)特性的，使大多數原本應被吸收而損耗的S偏振光線(電場方向垂直於入射面的線偏光)大都轉變成可利用的有效P偏振光線(電場方向平行於入射面的線偏光)，可提高螢幕的亮度。而其缺點：千層具特殊雙折射率堆疊與延伸，加工費用高；千層堆疊附著力與膨脹係數差異，施工中或使用中形成爆米花效應，中間層分離；彩虹干擾色，影響色的均勻性。3M has developed a reflective brightness enhancement film DBEF (Dual Brightness Enhancement Film), which uses multi-layer film technology, which consists of nearly one thousand layers with special birefrigence characteristics, so that most of the original should be absorbed and lost. The S-polarized light (the linearly polarized light whose direction of the electric field is perpendicular to the incident surface) is mostly converted into usable effective P-polarized light (the direction of the electric field is parallel to the incident plane), which improves the brightness of the screen. The shortcomings: the thousand layers have a special birefringence stacking and extension, the processing cost is high; the stacking adhesion and the expansion coefficient are different, the popcorn effect is formed during construction or in use, the middle layer is separated; the rainbow interference color, the color effect Uniformity.
另有日本日東電工公司，其利用膽固醇液晶(Cholesteric LC)配合1/4波長膜(Quarter wave film)，將光線型態一分為二，再經反覆循環得到類似的增亮效果。而上述膽固醇液晶的缺點在於：1.形成橢圓偏振光型態，因此必須再利用一相位差膜進一步修整為一線偏振光型態，方可被液晶使用；2.該1/4波長膜控制方向而同時對R、G、B產生作用，因此此種膽固醇液晶的技術應用難度高，亦因而具有高成本。3.由於成分為膽固醇液晶，因此對溫度的影響大。In addition, Japan Nitto Denko Co., Ltd. uses Cholesteric LC with a quarter wave film to divide the light pattern into two, and then repeat the cycle to obtain a similar brightening effect. The above-mentioned cholesteric liquid crystal has the disadvantages of: 1. forming an elliptically polarized light pattern, so it must be further trimmed into a linearly polarized light pattern by using a retardation film before being used by the liquid crystal; 2. The 1/4 wavelength film control direction At the same time, it has an effect on R, G, and B. Therefore, the technical application of such a cholesteric liquid crystal is difficult, and thus has a high cost. 3. Since the composition is cholesteric liquid crystal, it has a large influence on temperature.
另有一種利用「微鏡片擴散技術」來增加光學膜亮度增強效果的方法。其缺點在於：1.微結構與微結構之 間，會形成漏光區使得光無法均勻擴散，形成擴散不均。2.光的擴散能力與曲率半徑有關，因與厚度相關無法做大，擴散能力低。There is also a method of increasing the brightness enhancement effect of an optical film by using "microlens diffusion technology". The disadvantage is that: one of the microstructures and the microstructures, such that the light leakage region can be formed not uniformly diffused to form a diffusion unevenness. 2. The ability of light to diffuse is related to the radius of curvature. It cannot be made large in relation to thickness and has low diffusion ability.
亦有一種利用「奈米添加擴散」技術來製造光學膜的方法，其缺點：1.不同大小顆粒對於光學厚度(1/4λ)會形成不均一的反射與折射，會形成光的色散。2.高低折射率差異小的原料，使得擴散能力低。3.無光通道設計，大於臨界角的光會全反射光損失大，因此容易形成低穿透的光學膜。There is also a method for manufacturing an optical film by using "nano-added diffusion" technology, and the disadvantages thereof are as follows: 1. Particles of different sizes form uneven reflection and refraction for optical thickness (1/4λ), and light dispersion is formed. 2. Raw materials with small difference in high and low refractive index make the diffusion ability low. 3. No light channel design, light larger than the critical angle will have a large loss of total reflected light, so it is easy to form a low-penetration optical film.
以下則為上述幾種光學膜的優缺點比較表：The following is a comparison table of the advantages and disadvantages of the above several optical films:
由上述可知，各傳統光學膜均有其缺點，不外乎是光擴散效果不佳、結構複雜、或需要幾種光學膜一併使用、成本過高等等。As can be seen from the above, each of the conventional optical films has its disadvantages, such as poor light diffusion effect, complicated structure, or the need to use several optical films together, and the cost is too high.
本發明人有鑑於目前各種傳統光學膜仍具缺點，改良其不足與缺失，進而發明出一種光配位光學膜。The present inventors have invented a photo-coordinating optical film in view of the fact that various conventional optical films still have disadvantages and improved deficiencies and omissions.

And whether it is reflected or penetrating light, it contains part of P and S-polarized light, and the path of light is constantly changing direction, thus enabling light to diffuse.
本發明另一目的在於：當光由光疏進入光密時，光的相位會被改變180度相位反轉，穿透光相位不變而反射光再一次反射時為同周相，同周相光經間隙通道，來自不同區同周相的光，進而因光的疊加作用使光的亮度增加。Another object of the present invention is that when light is diffracted into light, the phase of the light is reversed by 180 degrees, the phase of the transmitted light is unchanged, and the reflected light is reflected again as the same phase, and the same phase is passed. The gap channel, the light from the same phase of different regions, and the brightness of the light is increased by the superposition of light.
本發明又一目的在於：經過多次的光折射與反射，部分P偏振光和S偏振光均轉成為P偏振光，使大多數原本應被吸收而損耗的S偏振光大都轉變成可被液晶利用的有效運用P偏振光。Another object of the present invention is that after a plurality of light refractions and reflections, part of the P-polarized light and the S-polarized light are converted into P-polarized light, so that most of the S-polarized light that should be absorbed and lost is converted into liquid crystal. Utilize the effective use of P-polarized light.
本發明另又一目的在於：當奈米核殼粒子顆粒小於可見光全波長時，光不被反射而形成高穿透，且奈米核殼粒子為半導性，在有光的環境為良導電性，因此具有抗靜電性。Another object of the present invention is to: when the nano-core shell particle is smaller than the full wavelength of visible light, the light is not reflected to form high penetration, and the nano-core particle is semi-conductive, and is good in a light environment. Sexual and therefore antistatic.
本發明另又一目的在於：此球狀奈米核殼粒子中心點會有一P亮點出現(Poisson)，由不同區來之光有因相位相同者互相加強，大為增加光之照度，其作用類似於正透鏡的聚焦功能，當接近最短出光距離時如直出的光提供光方向修正。Another object of the present invention is that the center point of the spherical nano-core particle has a P bright spot (Poisson), and the light from different regions is mutually enhanced by the same phase, which greatly increases the illumination of the light, and its effect Similar to the focusing function of the positive lens, light that is straight out when approaching the shortest light exit distance provides light direction correction.
本發明又一目的在於提供一種光配位光學膜，其主要利用奈米核殼粒子的光催化特性，當核殼粒子受光照射時，會產生電量相等，正負極性相反電荷的電子電洞對，在外加磁場時，依據霍爾效應電子與電洞受到不同方向的勞倫茲力而往不同方向上聚集，在聚集起來的電子與電洞之間會產生電場，粒子表面都是同一極性，由於表面並無導線因此不會產生電流，依據楞次定理此處會產生電流的電場。亦會依據安培定理產生磁場，電場與磁場為互相垂直且同周相，可超越物質性束縛，自由的以波的方式傳遞，該磁場中有電磁力在運作，因而改變核殼粒子在流體的運作狀態，當粒子表面都是同一極性，粒子之間會為了抵消磁場變化而產生另一磁場(楞次定理)，磁場間形成磁壓力使粒子往相反方向移動，這個應力張量屬第二階(r=2)張量，因此該核殼粒子會成為矩陣(matrix)分佈。使得該粒子可以均勻矩陣的排列在一UV有機膠中，最後在照射UV光使該粒子在有機膠中固化定位，形成一種光配位光學膜。Another object of the present invention is to provide a photo-coordinating optical film which mainly utilizes the photocatalytic properties of the nano-core shell particles, and when the core-shell particles are irradiated with light, an electron hole pair having the same electric quantity and opposite charge of the positive and negative polarities is generated. When the magnetic field is applied, the Hall effect electrons and the holes are concentrated in different directions by the Lorentz force in different directions, and an electric field is generated between the collected electrons and the holes, and the surface of the particles are all the same polarity due to There is no wire on the surface and therefore no current is generated. According to the 楞 theorem, the electric field of the current is generated here. The magnetic field is also generated according to the ampere theorem. The electric field and the magnetic field are perpendicular to each other and are in the same phase. They can transcend the physical bondage and transmit freely in the form of waves. In the magnetic field, electromagnetic force is working, thus changing the core-shell particles in the fluid. In the working state, when the surface of the particles are all of the same polarity, another magnetic field is generated between the particles to cancel the change of the magnetic field (the 定理 theorem), and the magnetic pressure is formed between the magnetic fields to move the particles in the opposite direction. This stress tensor belongs to the second order. (r = 2) tensor, so the core-shell particles will become a matrix distribution.

首先，光配位精密塗佈程序係具有一塗佈加工機台，在塗佈加工機台(20)上設置有複數滾輪(21)(22)以令上述薄膜基材(10)透過滾輪(21)(22)進行輸送。First, the optical coordination precision coating process has a coating processing machine, and a plurality of rollers (21) (22) are disposed on the coating processing machine (20) to allow the film substrate (10) to pass through the roller ( 21) (22) Carrying out.
上述具有奈米核殼粒子(100)的膠質(溶液)(101)經一位於塗佈加工機台(20)上的精密塗佈噴頭(30)對薄膜基材(10)進行塗佈噴灑，藉此均勻塗佈在薄膜基材(10)上而形成一奈米核殼粒子層(11)。該奈米核殼粒子層(11)厚度可約為5um。The colloid (solution) (101) having the nano core-shell particles (100) is coated and sprayed on the film substrate (10) via a precision coating nozzle (30) on the coating processing machine (20). Thereby, it is uniformly coated on the film substrate (10) to form a nano core-shell particle layer (11). The nano-core shell particle layer (11) may have a thickness of about 5 um.

Irradiation, the nano-core shell particle layer (11) is solidified and positioned. In the seventh figure, in order to control the distance of the nano-core particle (100) matrix, a magnetic field (70) is added during photocoordination, and the nano-shell particles (100) are exposed to a uniform magnetic field, resulting in U= The magnetic torque displacement energy of -m‧B can be corrected by changing the magnetic field energy as an optical film optimization operation. (U is the energy, the unit is joule; m is the magnetic moment, the unit is ampere ‧ square meters; B is the magnetic field strength)

以下則詳述可見光照射裝置的應用原理，即是光配位理論：當奈米核殼粒子(100)受光照射時，會產生電量相等，正負相反電荷電子電洞對，在外加磁場時，依據霍爾效應電子與電洞受到不同方向的勞倫茲力而往不同方向上聚集，在聚集起來的電子與電洞之間會產生電場，在量子電動力學裏，根據馬克士威方程式組(Maxwell's Equations)，隨著時間變化的電場產生了磁場，反之亦然。因此，一個振盪中的電場會產生振盪的磁場，而一個振盪中的磁場又會產生振盪的電場，如此，這些連續不斷同相振盪的電場和磁場，共同地形成了電磁波可超越物質性束縛，自由的以波的方式傳遞。當粒子表面皆具有同一極性時，粒子之間會為了抵消磁場變化而產生另一磁場(楞次定理)，磁場間形成磁壓力使粒子往相反方向移動，這個應力張量(Stress Tensor)屬第二階(r=2)張量，因此在一定點時間，該核殼粒子會成為均勻矩陣(Matrix)分佈。The following is a detailed description of the application principle of the visible light irradiation device, that is, the optical coordination theory: when the nano-core particle (100) is irradiated with light, the electricity is equal, positive and negative opposite charge electron hole pairs, when the magnetic field is applied, Hall effect electrons and holes are concentrated in different directions by Lorentz forces in different directions. An electric field is generated between the collected electrons and the holes. In quantum electrodynamics, according to Maxwell's equations (Maxwell's) Equations), an electric field that changes with time produces a magnetic field and vice versa. Therefore, an electric field in an oscillation generates an oscillating magnetic field, and an oscillating magnetic field generates an oscillating electric field. Thus, these continuously in-phase oscillating electric and magnetic fields together form an electromagnetic wave that can transcend material constraints and freedom. Pass in the wave. When the surface of the particles all have the same polarity, another magnetic field (the 定理 theorem) is generated between the particles to cancel the change of the magnetic field. The magnetic pressure is formed between the magnetic fields to move the particles in the opposite direction. This stress tensor (Stress Tensor) belongs to the first The second order (r = 2) tensor, so at a certain point in time, the core-shell particles will become a uniform matrix distribution.
當前述受可見光照射後的奈米核殼粒子(100)以上述矩陣進行排列時，此矩陣排列的奈米核殼粒子(100)之間留有一定間隙(X)讓光通過，如第四圖所示。當奈米核殼粒子(100)顆粒大於可見光全波長的光學厚度時，可見光區域的反射光，會再被一次被反射通過這間隙(X)，反射光與折射光同樣被改變行徑方向，當光的行徑被不斷的改變，因而能使光擴散。當反射光由光密進入光疏再一次反射時，光的相位會被改變180度，被再一次反射時與折射光為同相位的光，與經間隙(X)通道的光相遇，增加了光重疊機會，當光線的入射角大於臨界角時，會形成光的全反射改變光程行徑，會有光通過的損失，因有間隙(X)通道設計，會因材料之間折射率不同，臨界角也會不同，有類似擴大臨界角的功能，減少因全反射照成的光通過損失，又能因光的疊加作用使光的亮度增加。When the nano-core shell particles (100) irradiated with visible light are arranged in the above matrix, a gap (X) is left between the matrix-arranged nano-core shell particles (100) to allow light to pass, such as the fourth The figure shows. When the nano-core shell particle (100) particles are larger than the optical thickness of the full wavelength of visible light, the reflected light in the visible light region is once again reflected through the gap (X), and the reflected light and the refracted light are also changed in the direction of the path. The path of light is constantly changing, thus allowing light to spread. When the reflected light is reflected again by the light into the light, the phase of the light is changed by 180 degrees, and the light that is in phase with the refracted light is reflected again, and the light passing through the gap (X) channel increases. When the incident angle of light is greater than the critical angle, the total reflection of light will change the path length of the optical path, and there will be loss of light passage. Due to the gap (X) channel design, the refractive index between materials will be different. The critical angle will also be different, and there is a function similar to the expansion of the critical angle, which reduces the loss of light passing through the total reflection, and increases the brightness of the light due to the superposition of light.
在以上述矩陣排列的奈米核殼粒子(100)之中，當奈米核殼粒子(100)顆粒小於可見光全波長的光學厚度時，當光繞射一個小於波長粒徑的圓形障礙物時，會在圓形障礙物後方形成一個明亮點(Poisson亮點)。由不同區來之光有因相位相同者互相加強，大為增加光之照度，其作用類似於正透鏡的聚焦，因而有光修正功能。當該圓型障礙物粒徑小於400nm的光學厚度時，其不反射可見光，另一個含義就是沒有反射情形發生，有反射時才有光分量的變異，例如P光的部分反射成為S光，因此當P光通過時，不會被分解成P、S光，因此光的偏振分量不改變，做為上擴散為最佳之選擇。Among the nano-core shell particles (100) arranged in the above matrix, when the nano-core shell particle (100) particles are smaller than the optical thickness of the full wavelength of visible light, when the light is diffracted by a circular obstacle smaller than the wavelength particle diameter A bright spot (Poisson highlight) is formed behind the circular obstacle. The light from different zones is enhanced by the same phase, which greatly increases the illumination of the light, and its effect is similar to the focusing of the positive lens, thus having a light correction function. When the circular obstacle has an optical thickness of less than 400 nm, it does not reflect visible light, and the other meaning that no reflection occurs, and there is variation of the light component when there is reflection, for example, partial reflection of P light becomes S light, When the P light passes, it will not be decomposed into P and S light, so the polarization component of the light does not change, making it the best choice for upper diffusion.
藉由上述技術手段，上述具奈米核殼粒子層(11)(11a)的光配位光學膜(1)(1a)(1b)具有穿透、擴散、增亮、光方向修正、光的有效利用功能(偏極化)、抗靜電等六種以上的功效。而由於光配位光學膜(1)(1a)(1b)僅透過簡單的光照射加工與光定位製程即可完成成品，因此其加工成本低廉，產率高，因而具有低成本與高市場競爭力。此外本發明光配位光學膜尚有如下功效：1.抗靜電功能；2.增加穿透率功能；3.高擴散高穿透功能；4.光周相疊加增亮功能。5.減少因全反射照成的光通過損失功能。6.通過Poisson亮點光的的偏振分量不改變。By the above technical means, the optical coordination optical film (1) (1a) (1b) having the nano core-shell particle layer (11) (11a) has penetration, diffusion, brightness enhancement, light direction correction, and light. Efficient use of more than six functions such as function (polarization) and antistatic. Since the optical coordination optical film (1) (1a) (1b) can complete the finished product only through a simple light irradiation processing and optical positioning process, the processing cost is low, the yield is high, and thus the low cost and high market competition force. In addition, the optical coordination optical film of the invention has the following effects: 1. antistatic function; 2. increased penetration function; 3. high diffusion and high penetration function; 4. light-phase phase superimposed brightness enhancement function. 5. Reduce the light passing loss function due to total reflection. 6. The polarization component of the light passing through the Poisson bright spot does not change.
