Description

導光板、平面發光裝置、液晶顯示裝置、液晶顯示終端設備及導光板的製造方法 Light guide plate, planar light-emitting device, liquid crystal display device, liquid crystal display terminal device, and method of manufacturing light guide plate

本發明係關於導光板、平面發光裝置、液晶顯示裝置、液晶顯示終端設備及該導光板的製造方法。 The present invention relates to a light guide plate, a planar light-emitting device, a liquid crystal display device, a liquid crystal display terminal device, and a method of manufacturing the light guide plate.

通常，液晶顯示裝置包括顯示圖像的液晶顯示面板和將光線提供給液晶顯示面板的平面發光裝置。液晶顯示面板包括兩個透明基底和設置在該兩個基底之間的液晶層，以回應於由電信號引起的液晶層的液晶分子的排列的變化而顯示圖像。 Generally, a liquid crystal display device includes a liquid crystal display panel that displays an image and a planar light emitting device that supplies light to the liquid crystal display panel. The liquid crystal display panel includes two transparent substrates and a liquid crystal layer disposed between the two substrates to display an image in response to a change in alignment of liquid crystal molecules of the liquid crystal layer caused by an electrical signal.

平面發光裝置根據光源設置位置分為直下式平面發光裝置和側光式平面發光裝置。 The planar light-emitting device is divided into a direct-type planar light-emitting device and an edge-light planar light-emitting device according to the light source setting position.

直下式平面發光裝置具有位於與液晶面板疊置的區域中的多個光源。然後，由於需要液晶面板和光源之間具有一定的均光距離所以較厚，還有光線損耗較大的均光板，以便將光源均勻地提供到液晶面板上，所以導致液晶顯示裝置的厚度、成本、功耗、故障率增加。 The direct type planar light emitting device has a plurality of light sources located in a region overlapping the liquid crystal panel. Then, since it is required to have a certain uniform light distance between the liquid crystal panel and the light source, it is thick, and there is a light-area plate with a large light loss, so that the light source is uniformly supplied to the liquid crystal panel, thereby causing the thickness and cost of the liquid crystal display device. , power consumption, failure rate increased.

側光式平面發光裝置，是將光源設置在液晶面板的外側且不在同一平面中而是與液晶面板疊置，且使用具有一定厚度的導光板將來自區域外部的光線均勻地提供到液晶面板上。雖然由於從光源發射的光線經導光板的傳輸和轉 換，其中部分光線被損耗。但是，隨著液晶顯示裝置向著大尺寸、超薄化、低功耗、高亮度、低成本方向發展，而側光式平面發光裝置卻具有超薄美觀、均勻度好、成本低、故障率低等優勢，所以側光式平面發光裝置是未來液晶顯示背光的主流。 The edge-light type planar light-emitting device is disposed on the outer side of the liquid crystal panel and is not in the same plane but is stacked on the liquid crystal panel, and uses a light guide plate having a certain thickness to uniformly supply light from the outside of the region to the liquid crystal panel. . Although the light emitted from the light source is transmitted and transferred through the light guide plate Change, part of the light is lost. However, as the liquid crystal display device is developed toward large size, ultra-thin, low power consumption, high brightness, and low cost, the edge-lit planar light-emitting device has ultra-thin aesthetics, good uniformity, low cost, and low failure rate. Other advantages, so the edge-lit planar light-emitting device is the mainstream of future liquid crystal display backlights.

根據臺灣工研院的資料，側光式平面發光裝置的光線傳輸中的損耗也較大，假設光源發出的光是100%，經過側光式平面發光裝置的導光板後只有約60%的光線出來進入光學薄膜和液晶面板。由於導光板是將從入光側端面接收到的光線經傳輸轉換成較大面積的均勻平面發光且朝一個方法發射，可見它實現功能的難度之高之大，所以導光板是平面發光裝置中的重要核心部件，從而也導致光線傳輸時損耗高達40%之多，所以如何減少光線在導光板內部傳輸轉換過程中的損耗是全球光電技術人員重要研究物件。 According to the data of the Taiwan Industrial Technology Research Institute, the loss in the light transmission of the edge-lit planar light-emitting device is also large. It is assumed that the light emitted by the light source is 100%, and only about 60% of the light is passed through the light guide plate of the edge-light planar light-emitting device. Come out into the optical film and LCD panel. Since the light guide plate converts the light received from the light incident side end surface into a uniform planar light emission of a large area and emits it toward one method, it can be seen that it is difficult to realize the function, so the light guide plate is a planar light emitting device. The important core components, which also lead to loss of light transmission as much as 40%, so how to reduce the loss of light transmission inside the light guide plate conversion is an important research object of the global optoelectronic technicians.

導光板，其包括無色透明基板，用於接收光線射入內部的入光側端面，與入光側端面相對、相交的其餘貼塗有反射膜的反射側端面，並與其相交的光線從內部射出的出光平面和與出光平面相對的具有散射圖案的底平面構成。 a light guide plate comprising a colorless transparent substrate for receiving light entering the inner light incident side end surface, opposite to the light incident side end surface, and the remaining reflective side surface coated with the reflective film, and the light intersecting therewith is emitted from the inside The light exiting plane is formed by a bottom plane having a scattering pattern opposite to the light exiting plane.

目前，導光板的種類按大小、結構和製造工藝主要有兩種：一種是針對小尺寸採用注塑成型技術生產的光效率較高的微結構底平面導光板；另一種是針對大尺寸採用導光油墨在底平面上進行絲網印刷散射圖案的光效率較低的印刷型導光板。 At present, there are two main types of light guide plates in terms of size, structure and manufacturing process: one is a micro-structured bottom planar light guide plate produced by injection molding technology for small size; the other is light guide for large size. The ink is printed on the bottom plane with a light-efficient printing type light guide plate having a screen printing scattering pattern.

在小尺寸領域，目前隨著筆記型電腦、平板電腦、智 慧手機的液晶面板向著大尺寸、輕量化、超薄型、高光效率的發展和液晶顯示技術的提升，勢必要求導光板更輕更薄，從原來2.00MM左右向著0.8MM以下發展，由於厚度變薄，這在導光板成型方面將會出現一些問題。如果期望利用傳統的射出成型技術完成薄型導光板，那麼在設備上就必須改用高射速的射出成型機才行，當然目前一般所使用的射出成型也可以生產，但是，卻會面臨平整性和量產性的問題。但射速過高時，易因保壓壓力過大而產生殘留應力及分子定向等問題，進而造成翹曲變形的發生。所以，對於導光板業者而言，也就不斷的追求更新的技術，來生產低成本的薄型導光板。 In the small size field, currently with notebooks, tablets, and wisdom The LCD panel of Hui mobile phone is facing the development of large size, light weight, ultra-thin, high light efficiency and liquid crystal display technology. It is bound to require light guide plate to be lighter and thinner. It will develop from about 2.00MM to below 0.8MM, due to thickness change. Thin, this will cause some problems in the formation of the light guide plate. If it is desired to use a traditional injection molding technology to complete a thin light guide plate, then it is necessary to use a high-speed injection molding machine on the equipment. Of course, the injection molding currently used can also be produced, but it will face flatness and Mass production problems. However, when the rate of fire is too high, problems such as residual stress and molecular orientation may occur due to excessive pressure of the holding pressure, which may cause warping deformation. Therefore, for the light guide plate industry, it is constantly pursuing newer technologies to produce low-cost thin light guide plates.

在大中尺寸領域，雖然在專利資料庫中有許多光效率較高的微結構導光板，但真正要實現批量生產時都遇到工藝技術無法解決，有的採用雷射技術或電腦雕刻技術來製作，不僅很慢而且光效率和均勻性都不理想，無法滿足現代液晶顯示背部照明和平板照明的要求。因此，到目前為止仍然採用導光油墨在導光板底平面上進行絲網印刷散射圖案的方法製得。在專利資料庫中有申請號200710163134.5的公告文獻，其公開的方案為，在導光油墨中添加徑粒4μm至6μm的丙烯酸珠；也有專利號02149645.5、02151636.7、02250620.9的專利公告，都採用分別在導光油墨中添加SiO2、PMMA等散射粒子，由於添加這些顆粒都在導光油墨中，而丙烯酸珠、PMMA和油墨都是相似的丙烯酸樹脂，所以會直接溶解了，像SiO2 本身也是導光油墨中的一種原料，再添加進去沒有必要，對光效率不會有什麼提高。還有專利號02152108.5的專利公告，是將10μm至50μm有機填充球粒加入黏合劑中均勻塗布在導光板的出光平面上，這裡用的一般是類似三氯甲烷這樣的水劑性質的壓克力黏合劑，而不是膏狀黏合膠，又是整個表面塗布而不是製作成圖案，這樣破壞了導光板的全反射原理，使光線無法傳遞到中心區域，再則他們的發明目的是為了替代擴散膜的作用節省背光模組的成本而已。現有技術的絲網印刷導光板在光線傳遞和轉換過程中不僅光能損耗較大，而且在生產過程中還釋放有毒氣體損害生產員工的身體健康，所以在小尺寸領域中早已淘汰，但生產小尺寸的注塑成型生產工藝又無法在大尺寸導光板上實現。隨著液晶電視、液晶顯示器和平面發光照明裝置的尺寸越來越大，節能減排責任的越來越重，和面對全球各國頒佈強制性能效等級的壓力，對大尺寸高效節能導光板及其生產製造技術提出了更嚴峻的挑戰。 In the large and medium size field, although there are many light-efficient micro-structured light guide plates in the patent database, it is impossible to solve the technical problems in the mass production, and some use laser technology or computer engraving technology. The production is not only slow but also not ideal for light efficiency and uniformity, and cannot meet the requirements of modern LCD backlight and flat panel lighting. Therefore, a method of performing a screen printing scattering pattern on the bottom plane of the light guide plate by using a light guiding ink has been used so far. In the patent database, there is an announcement document of application number 200710163134.5, which discloses a method of adding acrylic beads having a diameter of 4 μm to 6 μm in a light guiding ink; and patent publications of patent numbers 02149645.5, 02151636.7, and 02250620.9 are respectively used in Scattering inks are added with scattering particles such as SiO 2 and PMMA. Since these particles are added to the light guiding ink, acrylic beads, PMMA and ink are similar acrylic resins, so they dissolve directly, like SiO 2 itself. It is not necessary to add a raw material to the light ink, and there is no improvement in light efficiency. There is also a patent publication No. 02152108.5, in which 10 μm to 50 μm organic filler pellets are uniformly applied to the light-emitting plane of the light guide plate in an adhesive, and generally used is an acrylic property such as chloroform. Adhesives, rather than paste adhesives, are coated on the entire surface rather than being patterned, thus destroying the principle of total reflection of the light guide plate, so that light cannot be transmitted to the central area, and their purpose is to replace the diffusion film. The role of saving the cost of the backlight module only. The prior art screen printing light guide plate not only has a large loss of light energy during the light transmission and conversion process, but also releases toxic gas in the production process to damage the health of the production staff, so it has been eliminated in the small size field, but the production is small. The size of the injection molding production process cannot be realized on a large-sized light guide plate. With the increasing size of LCD TVs, LCDs and flat-panel lighting devices, the responsibility for energy saving and emission reduction is becoming heavier, and the pressure on the large-scale high-efficiency energy-saving light guide plates Its manufacturing technology poses even more serious challenges.

有鑒於上述大中小尺寸導光板領域所面臨的困境，正是目前全球液晶平板顯示領域和照明領域亟待需要解決的技術難題。 In view of the above-mentioned difficulties in the field of large, medium and small-sized light guide plates, it is a technical problem that needs to be solved urgently in the field of liquid crystal panel display and illumination in the world.

本發明的第一個目的就是提供一種更加高效節能、更加環保、更加超薄、無論尺寸大中小都能實現低成本快速批量生產的新型導光板。為此，本發明採用以下技術方案： The first object of the present invention is to provide a new type of light guide plate which is more energy efficient, more environmentally friendly, and more ultra-thin, and can realize low-cost and rapid mass production regardless of size, medium and small size. To this end, the present invention adopts the following technical solutions:

一種導光板，其包括無色透明基板，所述基板具有用 於接收光線射入內部的入光側端面、光線從內部射出的出光平面、與出光平面相對的具有散射圖案的底平面，其特徵在於：該無色透明基板的底平面上及/或出光平面上設置無色透明黏合膠圖案層，且該黏合膠圖案層上植黏著數個微型散射顆粒而得到微結構散射立體圖案層，所植黏的微型散射顆粒全部或部分裸露凸出在黏合膠圖案層表面上，裸露凸出在黏合膠圖案層表面上的微型散射顆粒的一部分嵌入到無色透明黏合膠圖案層內被黏合膠牢固地黏合，其餘部分裸露凸出在無色透明黏合膠圖案層外。 A light guide plate comprising a colorless transparent substrate, the substrate having a light-emitting side end surface into which the light is incident, a light-emitting plane emitted from the inside, and a bottom plane having a scattering pattern opposite to the light-emitting plane, wherein the colorless transparent substrate has a bottom plane and/or a light-emitting plane A colorless transparent adhesive pattern layer is disposed, and a plurality of micro-scattering particles are implanted on the adhesive pattern layer to obtain a microstructure-scattering three-dimensional pattern layer, and the micro-scattering particles that are implanted are all exposed or partially exposed on the surface of the adhesive pattern layer. A part of the micro-scattering particles which are exposed on the surface of the adhesive pattern layer are embedded in the colorless transparent adhesive pattern layer and are firmly adhered by the adhesive, and the remaining portions are exposed to the outside of the colorless transparent adhesive pattern layer.

所述植黏是指微型散射顆粒借助外力進入無色透明黏合膠圖案層內使散射顆粒部分或全部嵌入到黏合膠圖案層內。 The viscous means that the micro scatter particles enter the colorless transparent adhesive pattern layer by external force to partially or completely embed the scattering particles into the adhesive pattern layer.

本發明的微型散射顆粒由無色透明黏合膠圖案層和透明基板黏合在一起，微型散射顆粒和基板之間可以是接觸的，也可以是非接觸的。 The micro-scattering particles of the present invention are bonded together by a colorless transparent adhesive pattern layer and a transparent substrate, and the micro-scattering particles and the substrate may be in contact or non-contact.

無色透明基板可根據需要厚度從0.3毫米到10毫米之間；材料為聚甲基丙烯酸甲酯、聚碳酸酯、MS樹脂、聚對苯二甲酸乙二醇酯、聚苯乙烯、聚氯乙烯、玻璃、超白玻璃、聚乙烯樹脂、非晶聚烯烴、ABS、PVC、PET等其中一種的軟板材或硬板材；結構是平板的也可是楔形板；透明基板出光平面上是光滑平整的，也可以垂直於入光側端面的微型條形狀半圓柱的陣列或微型條形狀三棱鏡陣列微結構的無色透明的板材。 The colorless transparent substrate may have a thickness of from 0.3 mm to 10 mm as required; the material is polymethyl methacrylate, polycarbonate, MS resin, polyethylene terephthalate, polystyrene, polyvinyl chloride, a soft or hard plate of glass, ultra-white glass, polyethylene resin, amorphous polyolefin, ABS, PVC, PET, etc.; the structure is a flat plate or a wedge plate; the transparent substrate is smooth and flat on the light-emitting plane, An array of micro-striped semi-cylindrical or micro-striped prism array microstructures that can be perpendicular to the light-incident end face.

該微結構散射立體圖案層可根據需要照明的產品需求 來進行光學設計。 The microstructure scattering three-dimensional pattern layer can be required according to the needs of the product to be illuminated For optical design.

若應用於液晶顯示背部照明、平板發光照明、薄型廣告燈箱之類的產品，所述的微結構散射立體圖案層可設計成由用於調節整體光線亮度和均勻度的具有一定間距的多個植黏有數個微型散射顆粒的微結構散射立體圖案層單元陣列分佈組成，在靠近入光側端面處小而稀疏，在遠離入光側端面處大而密。且每個微結構散射立體圖案層單元上都植黏有數個微結構散射顆粒。微結構散射立體圖案層單元圖形的輪廓可以是圓形、橢圓形等曲邊形，也可以是矩形、正方形、六邊形等多邊形。 If applied to liquid crystal display backlights, flat panel illuminations, thin advertising light boxes, etc., the microstructured scattering three-dimensional pattern layer can be designed to have a plurality of implants with a certain spacing for adjusting overall light brightness and uniformity. The micro-structured scattering three-dimensional pattern layer unit array having a plurality of micro-scattering particles is distributed, and is small and sparse at the end surface close to the light-incident side, and large and dense at the end surface far from the light-incident side. And each of the microstructure scattering three-dimensional pattern layer unit is implanted with a plurality of microstructure scattering particles. The outline of the microstructure scattering three-dimensional pattern layer unit pattern may be a curved shape such as a circle, an ellipse or the like, or may be a polygon such as a rectangle, a square, or a hexagon.

Or a graphical representation of a three-dimensional microstructure scattering block pattern or graphic with several micro-scattering particles.

無色透明黏合膠可以是含有紫外線光吸收劑的無色透明樹脂型黏合膠；也可以是熱固化無色透明樹脂型黏合膠；還可以是自然乾燥固化無色透明樹脂型黏合膠，目前廣泛使用的主要成份為聚甲基丙烯酸甲酯材質(PMMA)、環烯烴高分子材質(COP)或聚碳酸酯材質(PC)等樹脂材質。 The colorless transparent adhesive can be a colorless transparent resin type adhesive containing ultraviolet light absorber; it can also be a heat curing colorless transparent resin type adhesive; it can also be a natural dry curing colorless transparent resin type adhesive, and the main ingredients widely used at present. It is made of resin materials such as polymethyl methacrylate (PMMA), cycloolefin polymer (COP) or polycarbonate (PC).

該微結構散射顆粒是無色透明的顆粒。 The microstructured scattering particles are colorless, transparent particles.

當微型散射顆粒的粒徑小於黏合膠厚度，植黏時散射顆粒自然會完全嵌入黏合膠層內，對於嵌入黏合膠層內散射顆粒不會起到效果，不過在其上繼續重疊植黏有散射顆 粒，直到處在透明黏合膠層表面上散射顆粒才起到同樣的反射、全反射和折射的很好效果。微型散射顆粒的粒徑是黏合膠厚度的2倍時，對於球狀微型散射顆粒來說，其橫截面最大位置正好處在透明黏合膠表面，從而使從導光板內傳播到散射顆粒內的光線數量為較多，效果較好；微型散射顆粒粒徑大於黏合膠厚度時，下半部分嵌入黏合膠層內，也都具有上述同樣較好的效果。 When the particle size of the micro-scattering particles is smaller than the thickness of the adhesive, the scattering particles will naturally be completely embedded in the adhesive layer during the adhesion, and will not work for the scattering particles in the embedded adhesive layer, but continue to overlap the viscous scattering. One The particles, until the scattering particles on the surface of the transparent adhesive layer have the same effect of the same reflection, total reflection and refraction. When the particle size of the micro-scattering particles is twice the thickness of the adhesive, the maximum position of the cross-section of the spherical micro-scattering particles is on the surface of the transparent adhesive, so that the light propagates from the inside of the light guide plate into the scattering particles. The amount is more, the effect is better; when the particle size of the micro-scattering particles is larger than the thickness of the adhesive, the lower half is embedded in the adhesive layer, and all have the same good effects as above.

因此，微型散射顆粒粒徑一般在5微米到800微米之間，較佳是粒徑20微米至200微米。 Therefore, the micro-scattering particles generally have a particle diameter of from 5 μm to 800 μm, preferably from 20 μm to 200 μm.

透明微型散射顆粒折射率在1.1到2.8之間。 The transparent micro-scattering particles have a refractive index between 1.1 and 2.8.

透明微型散射顆粒材料為聚甲基丙烯酸甲酯、玻璃、聚碳酸酯、MS樹脂、聚對苯二甲酸乙二醇酯、聚乙烯、聚氯乙烯、聚丙烯腈、聚苯乙烯、尼龍或三聚氰胺等其中的一種或一種以上的混合。 The transparent micro scattering particle material is polymethyl methacrylate, glass, polycarbonate, MS resin, polyethylene terephthalate, polyethylene, polyvinyl chloride, polyacrylonitrile, polystyrene, nylon or melamine. Wait for one or more of these.

透明微型散射顆粒的形狀可以是圓錐體、球體等曲面體或三棱錐、多棱錐體等多面體，也可以是不規則多面體，也可以是幾種的混合。 The shape of the transparent micro-scattering particles may be a curved body such as a cone or a sphere, a polyhedron such as a triangular pyramid or a polygonal pyramid, or an irregular polyhedron, or a mixture of several kinds.

微型散射顆粒較佳方案是粒徑20微米至200微米，折射率1.93的球狀玻璃微珠；或者，是粒徑20微米至200微米，折射率1.49的透明聚甲基丙烯酸甲酯微球。 Preferred for the micro-scattering particles are spherical glass beads having a particle diameter of 20 μm to 200 μm and a refractive index of 1.93; or transparent polymethyl methacrylate microspheres having a particle diameter of 20 μm to 200 μm and a refractive index of 1.49.

因塗覆的無色透明黏合膠圖案層的厚度一般在10微米至80微米之間，較佳方案中的微型散射顆粒粒徑在20微米至200微米時，在散射顆粒植黏到透明黏合膠內的深度剛好在一半左右，這時散射顆粒跟透明黏合膠表面的橫 截面面積較大，從而使從導光板內傳播到散射顆粒內的光線數量為較多，從而使光線在射到透明顆粒的外表面(和外界空氣交界面)時所發生的反射光線、全反射光線和折射光線較多，就這樣大大提高了出光平面的亮度。 Since the thickness of the coated colorless transparent adhesive pattern layer is generally between 10 micrometers and 80 micrometers, in the preferred embodiment, the micro-scattering particle has a particle diameter of 20 micrometers to 200 micrometers, and the scattering particles are implanted into the transparent adhesive. The depth is just about half, when the scattering particles and the surface of the transparent adhesive are horizontal. The cross-sectional area is large, so that the amount of light propagating from the inside of the light guide plate to the scattering particles is large, so that the reflected light and total reflection occur when the light is incident on the outer surface of the transparent particle (interfacing with the outside air). The light and the refracted light are more, which greatly improves the brightness of the light exiting plane.

在微型散射顆粒材料上選擇，透光性越好，光線傳播時的損耗就越小，從而使出光平面的亮度提高，所以在眾多材料中還是聚甲基丙烯酸甲酯、環烯烴高分子材質(COP)、聚碳酸酯材質(PC)和玻璃透光性相對較好。又在同一種材料中折射率越高透明度越好，同樣能使出光平面的亮度再次提高，所以玻璃折射率1.93相對較高，而透明聚甲基丙烯酸甲酯折射率1.49，也同樣相對較高。 On the micro-scattering particle material, the better the light transmittance, the smaller the loss of light propagation, and the higher the brightness of the light-emitting plane. Therefore, in many materials, polymethyl methacrylate or cycloolefin polymer material is also used. COP), polycarbonate (PC) and glass have relatively good light transmission. In the same material, the higher the refractive index, the better the transparency, and the brightness of the light-emitting plane can be increased again. Therefore, the refractive index of the glass is relatively high at 1.93, and the refractive index of transparent polymethyl methacrylate is 1.49, which is also relatively high. .

該散射顆粒還可以是經過表面鍍膜處理的顆粒，所述膜可以是真空鍍鋁膜等金屬鍍膜。這樣的方案在光線通過導光板內傳播時當射到散射顆粒的鍍膜內表面(和黏合膠交界面)時發生象鏡子一樣的反射，不是象絲網印刷導光油墨的漫反射，這樣的光線損耗較小，所以光效率也就較高，而且批量生產簡單方便良品率高。 The scattering particles may also be particles subjected to surface coating treatment, and the film may be a metal plating film such as a vacuum aluminized film. Such a scheme produces a mirror-like reflection when the light is transmitted through the light guide plate when it hits the inner surface of the coating of the scattering particles (and the interface of the adhesive glue), not like the diffuse reflection of the screen printing light guiding ink. The loss is small, so the light efficiency is high, and the mass production is simple and convenient, and the yield is high.

此外，無論在透明基板的底平面上及/或出光平面上設置相同結構的微結構散射立體圖案層，都有較好的光效率效果。 In addition, whether the microstructure-scattering three-dimensional pattern layer of the same structure is disposed on the bottom plane of the transparent substrate and/or the light-emitting plane has a good light efficiency effect.

(4)提供所述的微型散射顆粒，採用植黏的方法，將上述提供的微型散射顆粒植黏到透明基板的無色透明黏合膠圖案上，該採用植黏的方法，是採用高壓靜電發生器產生的高壓靜電作用下的間斷性吸力和斥力將微型散射顆粒均勻地植黏到無色透明黏合膠圖案層上；或者，利用自由落體的衝力和重力將微型散射顆粒均勻地植黏到無色透明黏合膠圖案層上；或者，採用空氣壓縮機利用壓縮空氣的噴力將微型散射顆粒均勻地植黏到無色透明黏合膠圖案層上。 (4) providing the micro-scattering particles, and implanting the micro-scattering particles provided above onto the colorless transparent adhesive pattern of the transparent substrate by using a method of implanting, wherein the method of implanting is to use a high-voltage electrostatic generator.

對於小規格的導光板，可在拼版成大規格的情況下進行加工生產，然後再採用鐳射或機械切割成小規格，以提高生產效率。 For small-sized light guide plates, they can be processed in a large size, and then laser or mechanically cut into small sizes to improve production efficiency.

對於類似錐體等不規則形狀的散射顆粒可採用高壓靜電植黏技術進行植黏，這樣會使散射顆粒體積大的一頭得到的引力或斥力大，從而使其加速度快，實現其最先植入黏合膠層內，才能使這樣的導光板體現出更好的光效率效果。對於類似球體規則形狀的散射顆粒可採用依靠重力植黏的方法，這樣的設備投資更少更簡單，但在植黏時由於受外力的影響導致散射顆粒有可能向黏合膠單元圖形外滾動從而影響到光效率效果和牢度，相對來說還是採用高壓靜電植黏技術製作的方法光效率效果和牢度會更好。 For irregularly shaped scattering particles such as cones, high-pressure electrostatic viscosing techniques can be used for viscosification, which results in a large gravitational or repulsive force at the end of the large volume of the scattering particles, so that the acceleration is fast and the first implantation is achieved. In the adhesive layer, such a light guide plate can achieve better light efficiency effects. For scattering particles with a regular spherical shape, gravity-based grafting can be used. Such equipment investment is less simple and simpler. However, due to the influence of external force, the scattering particles may roll outside the adhesive unit pattern. To the light efficiency effect and fastness, the light efficiency effect and the fastness of the method made by the high-voltage electrostatic viscous technology are relatively better.

在無色透明黏合膠的選擇上優先選擇含有紫外線光吸收劑的無色透明樹脂型黏合膠，因這樣的黏合膠在光固化時比較環保沒有有害氣體釋放損害生產員工，並且固化速度快能耗少，生產出來的導光板光效率效果又相同。 In the choice of colorless transparent adhesive, the colorless transparent resin type adhesive containing ultraviolet light absorber is preferred. Because such adhesive is environmentally friendly, no harmful gas is released to damage the production staff, and the curing speed is fast and energy consumption is small. The light guide effect of the produced light guide plate is the same.

在無色透明黏合膠的主要材質和散射顆粒材質的選擇上，優先選擇跟透明基材材質相同的，因相同材質之間的黏合牢度最好。 In the selection of the main material and scattering particle material of the colorless transparent adhesive, the material of the transparent substrate is preferably the same, because the adhesion between the same materials is the best.

由於採用本發明的技術效果，本發明具有以下有益效果：根據光學原理和光線傳播路線分析，目前現有技術的導光板當導光板內傳播的光線碰到絲印導光油墨時發生的是漫反射，而本發明採用的技術方案是當導光板內傳播的光線，碰到真空鍍膜顆粒時像鏡子一樣進行反射；或者碰到類似於微型小透鏡的高透明高折射率的微型散射顆粒與外界空氣交界面上發生反射、全反射和折射，因此光能損 耗小，從而大大提高了對邊光源的利用率，以致實現高效節能的目的。 Due to the technical effects of the present invention, the present invention has the following beneficial effects: according to the optical principle and the light propagation route analysis, the light guide plate of the prior art is diffusely reflected when the light propagating in the light guide plate hits the silk screen light guiding ink. The technical solution adopted by the present invention is that when the light propagating in the light guide plate is reflected like a mirror when it encounters the vacuum coated particles, or the high transparent high refractive index micro scattering particles similar to the micro lenslets are compared with the outside air. Reflection, total reflection, and refraction occur on the interface, so light energy loss The consumption is small, thereby greatly improving the utilization rate of the side light source, so as to achieve the purpose of high efficiency and energy saving.

舉例對比，採用該技術製作的32吋液晶電視導光板樣品和現有技術液晶電視導光板樣品在相同背光模組中電壓電流不變情況下經國家電子電腦外部設備品質監督檢驗中心的NO：2012-3055《檢驗報告》亮度提升率達到28.8%，這在本領域內是難以預料的，一般情況下想要提高5%都很難。 For example, the 32-inch LCD TV light guide plate sample produced by this technology and the prior art LCD TV light guide plate sample are in the same backlight module with the same voltage and current, and the national electronic computer external equipment quality supervision and inspection center NO:2012- 3055 "Inspection Report" brightness increase rate reached 28.8%, which is unpredictable in the field, in general, it is difficult to increase 5%.

使用這樣的高效節能導光板所製作的背光模組、液晶顯示裝置、液晶電視、電腦、平板電腦、手機、平板照明燈具、發光鍵盤、發光儀錶盤、薄型廣告燈箱、發光標牌標識都能實現高效節能的目的。 Backlight modules, liquid crystal display devices, liquid crystal televisions, computers, tablet computers, mobile phones, flat panel lighting fixtures, illuminated keyboards, illuminated instrument panels, thin advertising light boxes, and illuminated signages made using such high-efficiency energy-saving light guide plates can be efficiently realized. The purpose of energy saving.

由於採用本發明的導光板製造方法，具有以下有益技術效果：就微結構導光板來說，最常見的是採用開制精密模具利用全電動注塑機進行注塑成型製得，但注塑成型工藝技術根本無法製造大尺寸導光板，所以高效率的微結構導光板在大尺寸領域一直難以實現。採用本發明的導光板製造方法，不僅能制得高效節能的大尺寸微結構導光板，使採用這樣的導光板的平面發光裝置的亮度得到顯著提高，而且投資少生產速度快。而且還能生產小規格導光板，且不會有注塑成型工藝技術所產生的導光板內應力問題所導致超薄導光板翹曲變形，從而大大提高了良品率。 Due to the use of the light guide plate manufacturing method of the present invention, the following beneficial technical effects are obtained: in the case of a microstructured light guide plate, the most common one is to use an all-electric precision injection molding machine for injection molding, but the injection molding process technology is fundamental. It is impossible to manufacture a large-sized light guide plate, so a highly efficient microstructure-based light guide plate has been difficult to realize in a large-sized field. According to the light guide plate manufacturing method of the present invention, not only a highly efficient and energy-saving large-sized microstructure light guide plate can be obtained, but also the brightness of the planar light-emitting device using such a light guide plate is remarkably improved, and the investment is low and the production speed is fast. Moreover, it can also produce a small-sized light guide plate, and there is no warpage deformation of the ultra-thin light guide plate caused by the stress problem in the light guide plate generated by the injection molding process technology, thereby greatly improving the yield rate.

因此該高效節能導光板及其生產方法的發明，由於它 具有立體微型結構、光效率高、投資少、成本低、生產速度快、良品率高、生產環保、無論大中小不受尺寸限制的優點，將會全面替代現有的15吋以上如液晶電視、電腦、顯示幕、平板燈具等配套的採用絲網印刷導光油墨製作的光效率較低的中大尺寸導光板。在手機、平板電腦、筆記本小尺寸領域，由於跟目前注塑成型微結構導光板的動輒至少投資幾千萬的全電動注塑設備和模具相比本發明的投資可以說少到微乎其微，尤其對超薄型趨勢的導光板還不會發生翹曲變形現象良品率高，且光效率相當，所以在小尺寸領域它將會和注塑成型微結構導光板共分半邊天，並會不斷蠶食這個領域。 Therefore, the invention of the high-efficiency energy-saving light guide plate and its production method is due to With three-dimensional micro structure, high light efficiency, low investment, low cost, fast production speed, high yield, environmental protection, no matter how large or small, no size limit, it will completely replace the existing 15吋 or more, such as LCD TV, computer Medium and large size light guide plates with low light efficiency made by screen printing light guide inks, such as display screens and flat panel lamps. In the small size field of mobile phones, tablets, and notebooks, the investment of the present invention can be said to be negligible compared to the current investment in micro-structured light guide plates, at least tens of millions of all-electric injection molding equipment and molds, especially for ultra-thin The trend of the light guide plate does not occur warp deformation phenomenon, high yield, and light efficiency is equivalent, so in the small size field it will be half-day with the injection molding microstructured light guide plate, and will continue to eat into this field.
