To form an air zone and pattern the adhesive material (adhesive pattern layer) to improve optical properties. In particular, the light guide plate is removed and replaced by the resin layer to significantly reduce the thickness of the lamp unit and further reduce the number of light sources.
圖3係根據本發明，繪示有一燈管裝置之主要部件圖示。Figure 3 is a diagram showing the main components of a lamp unit in accordance with the present invention.
參閱所附圖式，根據本發明之一燈管裝置可包括：複數個LED光源130形成於一印刷電路板110之上；一樹脂層140，以將光擴散並導引向前；以及一光學圖案層150，形成於樹脂層140之上，並包含有一光學圖案151。Referring to the drawings, a lamp device according to the present invention may include: a plurality of LED light sources 130 formed on a printed circuit board 110; a resin layer 140 to diffuse and guide light forward; and an optical The pattern layer 150 is formed over the resin layer 140 and includes an optical pattern 151.
特別是，光學圖案層150可包括一黏著圖案層153，形成一第一空氣區152環繞於該光學圖案周圍。In particular, the optical pattern layer 150 can include an adhesive pattern layer 153 that forms a first air region 152 that surrounds the optical pattern.
也就是說，黏著圖案層153可形成一間隔空間(第一空氣區)，其係具有一預設圖案於光學圖案151之上，並將黏著材料應用於特定區域，以實施該黏著圖案層。That is, the adhesive pattern layer 153 may form a space (first air region) having a predetermined pattern over the optical pattern 151 and applying an adhesive material to a specific region to implement the adhesive pattern layer.
也就是說，如圖式中之結構所示，有關光學圖案層150與黏著圖案層153間的排列關係，光學圖案層150可包括一第一基板150A以及一第二基板150B，其中包含有光學圖案；黏著圖案層153係被應用於除了環繞於該遮光圖案周圍之第一空氣層152之外的地方，以便黏著第一基板150A以及第二基板150B。在圖式中，雖然繪示有第一基板150A和第二基板150B，但在某些情況下，第二基板150B可被省略。That is, as shown in the structure of the figure, regarding the arrangement relationship between the optical pattern layer 150 and the adhesive pattern layer 153, the optical pattern layer 150 may include a first substrate 150A and a second substrate 150B including optical The pattern; the adhesive pattern layer 153 is applied to a place other than the first air layer 152 surrounding the light shielding pattern so as to adhere the first substrate 150A and the second substrate 150B. In the drawings, although the first substrate 150A and the second substrate 150B are illustrated, in some cases, the second substrate 150B may be omitted.
亦即，該光學圖案可形成為一遮光圖案，以避免自該LED光源所發出之光的匯聚；而為此目的，光學圖案151與LED光源130間需有校準調整(aligning)，且在校準調整後，係使用黏著材料來黏著該光學圖案，以確保固定力。當形成第一空氣層152之一圖案結構，係由形成黏著圖案層153來黏著時，可避免因將黏著材料放置於該遮光圖案或暗區之上所造成的局部亮區生成，並因空氣層之故，可增強光的均勻度。That is, the optical pattern can be formed as a light-shielding pattern to avoid convergence of light emitted from the LED light source; for this purpose, alignment alignment and alignment are required between the optical pattern 151 and the LED light source 130. After adjustment, the optical pattern is adhered using an adhesive material to ensure a fixing force. When a pattern structure of the first air layer 152 is formed and adhered by forming the adhesive pattern layer 153, local bright area generation due to placing the adhesive material on the light shielding pattern or the dark area can be avoided, and air is formed. The layer can enhance the uniformity of light.
如上所述，該燈管裝置之結構中，一反射膜120可被層壓於該印刷電路板之一上表面上，且進一步地，一擴散片170可被提供於樹脂層140之上，而具有一第二空氣區160之一氣隙單元可被提供於該光學圖案層與該擴散片之間。又，一稜鏡片以及一保護片等可被提供於該擴散片之上。As described above, in the structure of the lamp unit, a reflection film 120 can be laminated on the upper surface of one of the printed circuit boards, and further, a diffusion sheet 170 can be provided on the resin layer 140, and An air gap unit having a second air zone 160 may be provided between the optical pattern layer and the diffusion sheet. Further, a cymbal sheet and a protective sheet or the like may be provided on the diffusion sheet.
在下文中，將詳細說明根據本發明之燈管裝置。Hereinafter, the lamp tube device according to the present invention will be described in detail.
樹脂層140可被層壓，以圍繞LED光源130周圍，並用以擴散該光源側向發出之光。也就是說，習知導光板之功能係以樹脂層140來進行。需理解的是，該樹脂層可由任何能擴散光之材料所形成。舉例而言，根據本發明之之樹脂層的主要材料可為主要由氨基甲酸乙酯丙烯酸酯寡聚物(urethane acrylate oligomer)所構成之樹脂。舉例而言，作為合成寡聚物之氨基甲酸乙酯丙烯酸酯寡聚物係與高分子型(polymer type)之聚丙烯(polyacryl)的混合可被使用。當然，低沸點之反應性稀釋單體(low boiling point diluted type reactive monomer)如丙烯酸異冰片酯(isobornyl acrylate，IBOA)和丙烯酸羥基丙酯(hydroxylpropylacrylate，HPA)、丙烯酸2-羥基乙酯(2-hydroxyethyl acrylate，2-HEA)等等可被進一步地包含於其中，且作為添加劑(additives)的光起始劑(photo initiator)如1-羥基環己基苯基酮(1-hydroxycyclohexyl phenyl-ketone)等等、或者抗氧化劑(antioxidant)等等可被混合於其中。The resin layer 140 may be laminated to surround the LED light source 130 and to diffuse light emitted laterally from the light source. That is to say, the function of the conventional light guide plate is performed by the resin layer 140. It is to be understood that the resin layer can be formed of any material capable of diffusing light. For example, the main material of the resin layer according to the present invention may be a resin mainly composed of urethane acrylate oligomer. For example, a mixture of a urethane acrylate oligomer as a synthetic oligomer and a polymer type of polyacryl can be used. Of course, a low boiling point diluted type reactive monomer such as isobornyl acrylate (IBOA) and hydroxylpropyl acrylate (HPA), 2-hydroxyethyl acrylate (2- A hydroxyethyl acrylate, 2-HEA) or the like may be further included therein, and a photo initiator such as 1-hydroxycyclohexyl phenyl-ketone as an additive may be used. Etc., or an antioxidant or the like can be mixed therein.
又，該樹脂層可包括一珠粒141(bead)，以增加光的擴散及反射。該珠粒係以該樹脂層之一整體重量之0.01-0.3%被包括於該樹脂層之中。也就是說，該樹脂層與該珠粒係擴散、反射該LED側向發出之光，以使其向上行進。此處，如下文將說明的，當提供一反射膜120以及一反射圖案121時，可促進此反射功能。該樹脂層的存在係顯著地減少一習知導光板所佔據的厚度，進而使整體產品變得輕薄，並進一步地使產品具有彈性，令其得以被使用於一可撓式顯示裝置(flexible display)，具有廣泛的應用。Also, the resin layer may include a bead 141 to increase the diffusion and reflection of light. The beads are included in the resin layer in an amount of from 0.01 to 0.3% by weight based on the total weight of one of the resin layers. That is, the resin layer and the beads diffuse and reflect the light emitted laterally by the LED to travel upward. Here, as will be explained below, when a reflective film 120 and a reflective pattern 121 are provided, this reflective function can be promoted. The presence of the resin layer significantly reduces the thickness occupied by a conventional light guide plate, thereby making the overall product light and thin, and further making the product elastic, so that it can be used in a flexible display device (flexible display device) ), with a wide range of applications.
參閱圖4、5，根據本發明，繪示有光學圖案層150之製造方法。Referring to Figures 4 and 5, a method of fabricating an optical pattern layer 150 is illustrated in accordance with the present invention.
參閱圖3、4所繪示之整體結構，形成於樹脂層140上方之光學圖案層150可包括包含有一遮光圖案於其中之一第一基板150A以及一第二基板150B；且進一步地可包括一黏著圖案層153，其係被應用於除了環繞於光學圖案151周圍之第一空氣層之外的地方。也就是說，在流程次序上，首先是印刷該光學圖案於第一基板150A之上，然後形成環繞該光學圖案之黏著圖案層153，接著，第二基板150B係被黏著，以完整地形成光學圖案層150。當然，該光學圖案可形成於第二基板150B之上。Referring to the overall structure illustrated in FIGS. 3 and 4, the optical pattern layer 150 formed over the resin layer 140 may include a first substrate 150A and a second substrate 150B including a light shielding pattern; and further may include a The adhesive pattern layer 153 is applied to a place other than the first air layer surrounding the optical pattern 151. That is, in the flow sequence, first, the optical pattern is printed on the first substrate 150A, and then the adhesive pattern layer 153 surrounding the optical pattern is formed, and then the second substrate 150B is adhered to completely form the optical Pattern layer 150. Of course, the optical pattern can be formed over the second substrate 150B.
在此處，第一基板150A以及第二基板150B可包括具有絕佳光傳導率之材料，如PET。設置在第一基板150A以及第二基板150B之間的光學圖案，其功能基本上是阻止自該LED光源所發出之光的匯聚；且進一步的，該光學圖案可被以遮光圖案之形式於第一基板150A以及第二基板150B其中一者之上。另外，藉由將兩基板黏著為一黏著層，黏著材料被施用於該遮光圖案之周圍，可實施一校準調整。也就是說，第一基板150A以及第二基板150B之一黏著結構之功能係可為固定該印刷之遮光圖案151。又，該黏著層可由熱固性感壓膠(thermosetting PSA(pressure sensitive adhesive))、熱固性黏著材料、紫外線熱固性感壓型黏著材料所形成。Here, the first substrate 150A and the second substrate 150B may include a material having excellent light conductivity, such as PET. An optical pattern disposed between the first substrate 150A and the second substrate 150B, the function of which is substantially to prevent convergence of light emitted from the LED light source; and further, the optical pattern may be in the form of a light shielding pattern Above one of the substrate 150A and the second substrate 150B. In addition, by adhering the two substrates to an adhesive layer, an adhesive material is applied around the light-shielding pattern to perform a calibration adjustment. That is, the function of the adhesive structure of one of the first substrate 150A and the second substrate 150B may be to fix the printed light shielding pattern 151. Moreover, the adhesive layer can be formed by a thermosetting PSA (pressure sensitive adhesive), a thermosetting adhesive material, and an ultraviolet thermosetting adhesive type adhesive material.
在圖5中，係繪示有光學圖案151、黏著圖案層153、以及第一空氣區。In FIG. 5, an optical pattern 151, an adhesive pattern layer 153, and a first air zone are illustrated.
當黏著圖案層153係由使用黏著材料作為環繞被印刷為一特定圖案於該第一基板上之光學圖案151之周圍來形成時，該第二基板係被黏著，以形成一預設空間作為其中形成也一空氣層之一封閉結構，稱為「一第一空氣區」。由黏著圖案層153所形成之第一空氣區152之一形狀可為各種形狀如一圓形、橢圓形、矩形、正方形、或多邊形等等。該黏著圖案層可由熱固性感壓膠、熱固性黏著材料、紫外線熱固性感壓型黏著材料所形成。When the adhesive pattern layer 153 is formed by using an adhesive material as a periphery around the optical pattern 151 printed on a first substrate, the second substrate is adhered to form a predetermined space. A closed structure, also formed as an air layer, is referred to as a "first air zone." One of the first air regions 152 formed by the adhesive pattern layer 153 may have various shapes such as a circular shape, an elliptical shape, a rectangular shape, a square shape, or a polygonal shape. The adhesive pattern layer can be formed by a thermosetting elastic pressure adhesive, a thermosetting adhesive material, and an ultraviolet heat-curing pressure-sensitive adhesive material.
又，光學圖案151可形成為遮光圖案，以實施遮光效果，藉此以避免光強度太強，造成光學特性的降低，以及黃化現象的產生。也就是說，可使用遮光墨水(light shielding ink)來形成該遮光圖案，以阻止光的匯聚。Further, the optical pattern 151 may be formed as a light-shielding pattern to perform a light-shielding effect, thereby preventing the light intensity from being too strong, causing a decrease in optical characteristics, and a yellowing phenomenon. That is to say, the light shielding ink can be used to form the light shielding pattern to block the convergence of light.
在此處，該光學圖案並非用來完全地遮蔽光；一遮光度或擴散度可以該光學圖案之一來調整，以產生一部分遮光、擴散的結果。又，該光學圖案可較佳地由交疊複雜圖案之印刷結構來形成。此處，該交疊印刷結構係指先形成單一圖案，然後將一圖案形狀印刷在該圖案之上方。Here, the optical pattern is not intended to completely shield the light; a opacity or diffusivity may be adjusted by one of the optical patterns to produce a portion of the result of shading and diffusion. Also, the optical pattern may preferably be formed by a printed structure that overlaps the complex pattern. Here, the overlap printing structure refers to forming a single pattern first, and then printing a pattern shape over the pattern.
舉例而言，當形成光學圖案151時，一擴散圖案係使用包括選自由二氧化鈦(TiO2)、碳酸鈣(CaCo3)、硫酸鋇(BaSO4)、氧化鋁(Al2O3)、及矽其中一者之遮光墨水，以形成於聚合物膜下方；而使用包含鋁(Al)或鋁(Al)與二氧化鈦(TiO2)之混合物之遮光墨水所形成之一遮光圖案係被交疊印刷。也就是說，該擴散圖案係被白印刷(white-printed)於該聚合物膜之一表面上，然後該遮光圖案係形成於該擴散圖案之上方，形成一雙結構；反之亦然。當然，此圖案化設計可根據光效率、光強度、及遮光率之考量而變動。又，在一三層之依序層壓結構(sequential lamination configuration)中，作為一金屬圖案之該遮光圖案係被提供於一中間部分之上，而該擴散圖案系分別被提供於其上部分及下部分之上。在此三重結構中，可使用上述材料；在一較佳例中，具有絕佳折射率(refraction rate)之二氧化鈦(TiO2)可被使用來形成該擴散圖案其中一者，另一擴散圖案可使用二氧化鈦(TiO2)以及具有良好光穩定性與色彩感覺(color feeling)之碳酸鈣(CaCo3)，而該遮光圖案係使用具有絕佳遮蔽性(hiding property)之鋁(Al)來形成，其中此三重結構可確保光效率與均勻度。特別是，碳酸鈣(CaCo3)係由扣除黃化光(yellowish light)曝光來最終地實施白光，藉此確保更穩定的光效率；進一步地，除碳酸鈣(CaCo3)以外，無機材料如硫酸鋇(BaSO4)、氧化鋁(Al2O3)、及矽，一反射膜120可進一步被提供。該反射膜120可具有一反射材料，以擴散自該LED光源所發出之光；其係可進一步地由一白印刷方法，而包括一反射圖案121。特別是，反射膜120可被層壓於該印刷電路板之上，且進一步地LED光源130係通過形成在該反射膜上之一孔而向外突伸。當該LED光源係被提供為一側發光式LED時，如上所述，光源的數量可被顯著地減少，且進一步地一反射圖案121可被提供，用以顯著地改善一光反射率，進而增加縮減率(reduction rate)。在此處。該反射圖案可使用包括選自由二氧化鈦(TiO2)、碳酸鈣(CaCo3)、硫酸鋇(BaSO4)、氧化鋁(Al2O3)、矽、及聚苯乙烯(Poly Styrene)其中一者之一反射墨水來印刷。該反射圖案可被形成於該LED光源之一發光方向，且特別地，該圖案係被排列為使該圖案密度係在其自該LED光源之發光方向退離時，調整為漸高。For example, when the optical pattern 151 is formed, a diffusion pattern is selected to be selected from the group consisting of titanium dioxide (TiO 2 ), calcium carbonate (CaCo 3 ), barium sulfate (BaSO 4 ), aluminum oxide (Al 2 O 3 ), and germanium. One of the light-shielding inks is formed under the polymer film; and one of the light-shielding patterns formed using the light-shielding ink containing aluminum (Al) or a mixture of aluminum (Al) and titanium oxide (TiO 2 ) is overlap printed. That is, the diffusion pattern is white-printed on the surface of one of the polymer films, and then the light-shielding pattern is formed over the diffusion pattern to form a double structure; and vice versa. Of course, this patterned design can vary depending on light efficiency, light intensity, and shading rate. Further, in a three-layer sequential lamination configuration, the light-shielding pattern as a metal pattern is provided on an intermediate portion, and the diffusion patterns are respectively provided on the upper portion thereof. Above the lower part. In the triple structure, the above materials may be used; in a preferred embodiment, titanium dioxide (TiO 2 ) having an excellent refractive index may be used to form one of the diffusion patterns, and another diffusion pattern may be used. Titanium dioxide (TiO 2 ) and calcium carbonate (CaCo 3 ) having good light stability and color feeling are used, and the light-shielding pattern is formed using aluminum (Al) having an excellent hiding property. This triple structure ensures light efficiency and uniformity. In particular, calcium carbonate (CaCo 3 ) is finally subjected to white light by subtracting yellowish light exposure, thereby ensuring more stable light efficiency; further, in addition to calcium carbonate (CaCo 3 ), inorganic materials such as barium sulfate (BaSO 4 ), alumina (Al 2 O 3 ), and tantalum, a reflective film 120 may be further provided. The reflective film 120 can have a reflective material to diffuse light emitted from the LED light source; it can be further processed by a white printing method including a reflective pattern 121. In particular, the reflective film 120 may be laminated on the printed circuit board, and further the LED light source 130 protrudes outward through a hole formed in the reflective film. When the LED light source is provided as a one-side LED, as described above, the number of light sources can be significantly reduced, and further a reflective pattern 121 can be provided to significantly improve a light reflectivity, and thus Increase the reduction rate. Here. The reflective pattern may be selected to include one selected from the group consisting of titanium oxide (TiO 2 ), calcium carbonate (CaCo 3 ), barium sulfate (BaSO 4 ), aluminum oxide (Al 2 O 3 ), antimony, and polystyrene (Poly Styrene). One of them reflects the ink to print. The reflective pattern may be formed in a direction in which one of the LED light sources emits light, and in particular, the pattern is arranged such that the pattern density is adjusted to be progressively higher as it retreats from the direction of illumination of the LED light source.
又，如圖3所示，一氣隙單元可被進一步地提供於光學圖案層150與反射片170之間。圖6係繪示有如圖3、4所示之光學圖案層150與反射片170之間的氣隙單元。Also, as shown in FIG. 3, an air gap unit may be further provided between the optical pattern layer 150 and the reflective sheet 170. FIG. 6 illustrates an air gap unit between the optical pattern layer 150 and the reflective sheet 170 as shown in FIGS. 3 and 4.
也就是說，在根據本發明之燈管裝置結構中，一空氣層(第二空氣區160)係額外地構成於光學圖案層150與反射片170之間。而因第二空氣區160之出現，自該光源所發出之光係被擴散，進而改良光均勻度。又，為使光通過樹脂層140及光學圖案層150之一光線偏離(light deviation)最小化，第二空氣區160之一厚度可為0.01-2mm。That is, in the lamp tube device structure according to the present invention, an air layer (second air region 160) is additionally formed between the optical pattern layer 150 and the reflection sheet 170. Due to the appearance of the second air zone 160, the light emitted from the light source is diffused, thereby improving the light uniformity. Further, in order to minimize light deviation of light passing through one of the resin layer 140 and the optical pattern layer 150, one of the second air regions 160 may have a thickness of 0.01 to 2 mm.
此處，在第二空氣區160中，空氣層可形成於該擴散片之下方，其中，該空氣層係指稱包括第二空氣區之「氣隙單元」，以此結構所實施。該氣隙單元可包括所有由處理該擴散片本身以形成空氣區(空氣層)，或者形成一獨立結構於該擴散片下方以形成空氣區之結構。也就是說，如圖6(a)所示，一間隔物171(spacer)係形成於擴散片170之下方，以形成第二空氣區160；或者，如圖6(b)所示，由將該擴散片之下部分圖案化而提供一架橋172(bridge)，進而形成第二空氣區160靠近該下部層。該整體成型之結構可隨著圖案化之形狀，亦即形成該空氣區之形狀，來變化。結果是，很明顯地該架橋之形狀可被變動，而仍落在本發明之申請範圍內。又，如圖6(c)所示，除了將該擴散片之下表面圖案化外，空氣區160可由使用一獨立結構來形成。圖式所繪示之結構中，架橋174係由一間隔件(spacer member)所形成；然而，本發明之主旨係包括此結構，故形成該空氣層於該擴散片之下方的各種變化均應落在本發明之主旨內。如圖6(d)所示，如同(b)所示之圖案化該擴散片本身之配置，以及如同(c)所示之除一單一空氣層外另外使用一獨立結構之配置，空氣區160藉由應用可實施一獨立空氣層之結構175、176，而形成為複數層之形式。Here, in the second air zone 160, an air layer may be formed below the diffusion sheet, wherein the air layer is referred to as an "air gap unit" including the second air zone, and is implemented by this structure. The air gap unit may include all structures that process the diffuser itself to form an air zone (air layer) or form a separate structure below the diffuser to form an air zone. That is, as shown in FIG. 6(a), a spacer 171 is formed below the diffusion sheet 170 to form the second air region 160; or, as shown in FIG. 6(b), The lower portion of the diffuser is patterned to provide a bridge 172 which in turn forms a second air zone 160 adjacent the lower layer. The integrally formed structure can vary with the shape of the pattern, that is, the shape of the air zone. As a result, it is apparent that the shape of the bridge can be varied while still falling within the scope of the present application. Further, as shown in Fig. 6(c), in addition to patterning the lower surface of the diffusion sheet, the air region 160 may be formed using a separate structure. In the structure illustrated in the drawings, the bridge 174 is formed by a spacer member; however, the subject matter of the present invention includes the structure, so that various changes in the formation of the air layer below the diffusion sheet should be It falls within the gist of the present invention. As shown in FIG. 6(d), the configuration of the diffusion sheet itself is patterned as shown in (b), and the air region 160 is additionally used in addition to a single air layer as shown in (c). It is formed in the form of a plurality of layers by applying structures 175, 176 that can implement a separate air layer.
根據本發明之燈管裝置，如圖7所示，可由發光光源130之排列配置來實施。也就是說，LED光源130可使用側發光式LED排列來配置，以減少光源之數量。The lamp tube device according to the present invention can be implemented by the arrangement of the light-emitting sources 130 as shown in FIG. That is, the LED light source 130 can be configured using a side-emitting LED arrangement to reduce the number of light sources.
圖8係根據本發明，繪示有燈管裝置之另一實施例。Figure 8 is a diagram showing another embodiment of a lamp unit in accordance with the present invention.
參閱圖8，據本發明之燈管裝置可包括：複數個LED光源130形成於一印刷電路板110之上；一反射膜120，包含有一反射圖案121，於印刷電路板110之上；以及一樹脂層140層壓於印刷電路板110之上，將來自LED光源130之光擴散並導引向上。特別是，在本發明中，該反射圖案可由具有空氣結構之陶瓷材料作為圖案材料來形成。Referring to FIG. 8, the lamp device of the present invention may include: a plurality of LED light sources 130 formed on a printed circuit board 110; a reflective film 120 including a reflective pattern 121 on the printed circuit board 110; The resin layer 140 is laminated on the printed circuit board 110 to diffuse and direct the light from the LED light source 130 upward. In particular, in the present invention, the reflective pattern may be formed of a ceramic material having an air structure as a pattern material.
當然，在此情況下，反射膜120可具有一溝槽於其上表面上以容該LED通過，且進一步地可包括一光學圖案層150，其係包含有一擴散片170形成於樹脂層140之上方以及一光學圖案設於該樹脂層與該擴散片之間。Of course, in this case, the reflective film 120 may have a groove on the upper surface thereof to accommodate the LED, and further may include an optical pattern layer 150 including a diffusion sheet 170 formed on the resin layer 140. An upper and an optical pattern are disposed between the resin layer and the diffusion sheet.
參閱圖8、9，反射圖案121可形成為一圖案化形狀於該印刷電路板之上表面上。舉例而言，反射圖案121之一整體剖面，如圖所示，可朝向該光源被不同地圖案化為一楔型或一平坦型等等。該反射圖案可使用不同的印刷方法來印刷，如凹版印刷(gravure printing)及絹網(serigraph)印刷等。反射圖案121可由具有空氣結構122之陶瓷材料作為一圖案材料來形成，該圖案材料之一折射率係為1-1.4，且其中可包括內部提供有真空或空氣之結構122，如氣泡。Referring to Figures 8 and 9, the reflective pattern 121 may be formed in a patterned shape on the upper surface of the printed circuit board. For example, one of the overall patterns of the reflective pattern 121, as shown, can be patterned differently toward the light source into a wedge or a flat type or the like. The reflective pattern can be printed using different printing methods, such as gravure printing and serigraph printing. The reflective pattern 121 may be formed of a ceramic material having an air structure 122 as a pattern material having a refractive index of 1-1.4, and may include a structure 122, such as a bubble, internally provided with a vacuum or air.
也就是說，空氣結構122可為一玻璃氣泡，其係包括以幾奈米厚的玻璃來包圍幾十微米的真空所形成之氣泡材料。That is, the air structure 122 may be a glass bubble including a bubble material formed by a vacuum of several tens of micrometers surrounded by a vacuum of several tens of micrometers.
作為該圖案材料之一例，包含有空氣結構122之該陶瓷材料可被固定至本發明中形成該樹脂層之該用於導光板之樹脂，且該反射圖案可輕易地由墨水印刷方法來形成，以提供各種形狀及圖案。該用於導光板之樹脂係指用以實施樹脂層140之材料且用於樹脂層140之材料可為與第三實施例中相同。As an example of the pattern material, the ceramic material including the air structure 122 may be fixed to the resin for the light guide plate forming the resin layer in the present invention, and the reflection pattern may be easily formed by an ink printing method. To provide a variety of shapes and patterns. The resin for the light guide plate means the material for carrying out the resin layer 140 and the material for the resin layer 140 may be the same as in the third embodiment.
當該反射圖案形成時，其係可以一圖案材料，如混有包括選自由二氧化鈦(TiO2)、碳酸鈣(CaCo3)、硫酸鋇(BaSO4)、氧化鋁(Al2O3)、矽、及聚苯乙烯(Poly Styrene)其中一者之一反射墨水以及包含有該空氣結構之一陶瓷材料之混合物來提供印刷該反射圖案。又，當反射圖案121需要成為一特定結構如一楔形時，可由一轉印方法(stamping method)或壓製方法(pressing method)來製造所需之形狀。根據包含有空氣之反射圖案，自該光源所發出之光，因該反射圖案和以低耐熱性材料印刷之遮光圖案之故，係被完全反射，以改善整體亮度與光均勻度。When the reflective pattern is formed, it may be a pattern material, such as mixed and selected from the group consisting of titanium dioxide (TiO 2 ), calcium carbonate (CaCo 3 ), barium sulfate (BaSO 4 ), aluminum oxide (Al 2 O 3 ), germanium. And one of polystyrene (Poly Styrene) reflects ink and a mixture of ceramic materials comprising one of the air structures to provide printing of the reflective pattern. Further, when the reflective pattern 121 needs to be a specific structure such as a wedge shape, a desired shape can be produced by a stamping method or a pressing method. According to the reflection pattern containing air, the light emitted from the light source is completely reflected by the reflection pattern and the light-shielding pattern printed with a low heat-resistant material to improve overall brightness and light uniformity.
圖9係根據本發明另一實施例，繪示有與圖8所示不同之結構。其中，樹脂層140與擴散片170之間的光學圖案151可由使用一圖案材料來形成。該圖案材料之一折射率，與前述者相同，係為1-1.4，且該材料包括具有真空或空氣於其中之空氣結構之材料如玻璃氣泡。另，與該反射圖案相似，由樹脂層140與該圖案材料組成之該材料係可被混合以印刷該光學圖案。FIG. 9 is a view showing a structure different from that shown in FIG. 8 according to another embodiment of the present invention. The optical pattern 151 between the resin layer 140 and the diffusion sheet 170 may be formed using a pattern material. The refractive index of one of the pattern materials, which is the same as the foregoing, is 1-1.4, and the material includes a material such as glass bubbles having a vacuum or air structure therein. Further, similarly to the reflective pattern, the material composed of the resin layer 140 and the pattern material may be mixed to print the optical pattern.
同時，在圖9中，係繪示有在形成光學圖案151時直接將該光學圖案形成於該擴散圖案下方之一結構；然而，該結構並不限制於此，且該光學圖案可被應用於圖8所示之燈管裝置。Meanwhile, in FIG. 9, there is shown a structure in which the optical pattern is directly formed under the diffusion pattern when the optical pattern 151 is formed; however, the structure is not limited thereto, and the optical pattern can be applied. Figure 8 shows the lamp unit.
另外，與此方法不同，當光學圖案151形成時，可形成下列所述者：由使用包含空氣結構之陶瓷材料與包括二氧化鈦(TiO2)、碳酸鈣(CaCo3)、硫酸鋇(BaSO4)、氧化鋁(Al2O3)、矽、其中超過一者之遮光墨水之混合物，以一發光方向形成於該聚合物膜下方之擴散圖案；由使用包含鋁(Al)或鋁(Al)與二氧化鈦(TiO2)之混合物之遮光墨水與包含空氣結構之陶瓷材料之混合物所形成之遮光圖案；或者，上述圖案之交疊結構。也就是說，在本實施例中，當反射圖案或光學圖案形成於該反射膜上時，該些圖案可使用包括了包含空氣結構之陶瓷材料的圖案材料來印刷形成。In addition, unlike this method, when the optical pattern 151 is formed, the following can be formed: by using a ceramic material containing an air structure and including titanium oxide (TiO 2 ), calcium carbonate (CaCo 3 ), barium sulfate (BaSO 4 ) a mixture of aluminum oxide (Al 2 O 3 ), antimony, more than one of the light-shielding inks, formed in a light-emitting direction under the polymer film; using aluminum (Al) or aluminum (Al) a light-shielding pattern formed by a mixture of a light-shielding ink of a mixture of titanium oxide (TiO 2 ) and a ceramic material containing an air structure; or an overlapping structure of the above-mentioned patterns. That is, in the present embodiment, when a reflective pattern or an optical pattern is formed on the reflective film, the patterns may be formed by printing using a pattern material including a ceramic material including an air structure.
根據本發明之燈管裝置可由下述配置結構與操作來應用於液晶顯示器上。參閱圖3、8，光係自一側光式LED130以一側向發出，且該光係由取代習知導光板之樹脂層反射、擴散，藉此，以光學圖案層150來避免一光匯聚，並以形成於擴散片下方之第二空氣區來將光線偏移情況降到最低。更詳細之說明，由反射膜120與反射圖案121所發出之光之一反射效率係被提升，以將該光導引向上。通過樹脂層140之光係被形成在光學圖案層150之上的光學圖案151擴散或屏蔽，然後被霧化之光(refined light)的光學特性係再一次地被形成於該擴散片下方之氣隙單元所霧化，以增加均勻度，接著以白光之形式，通過額外提供之一稜鏡片180及反射式偏光增亮膜190(Dual Brightness Enhancement Film，DBEF)，入射於一液晶顯示器面板。The lamp unit according to the present invention can be applied to a liquid crystal display by the following configuration and operation. Referring to FIGS. 3 and 8, the light is emitted from one side of the light-emitting LED 130 in a side direction, and the light is reflected and diffused by a resin layer replacing the conventional light guide plate, thereby avoiding a light convergence by the optical pattern layer 150. The light deflection is minimized by a second air zone formed below the diffuser. In more detail, the reflection efficiency of one of the light emitted by the reflective film 120 and the reflective pattern 121 is raised to direct the light upward. The optical system 151 formed on the optical pattern layer 150 is diffused or shielded by the light system of the resin layer 140, and then the optical characteristics of the refred light are once again formed under the diffusion sheet. The gap unit is atomized to increase the uniformity, and then incident on a liquid crystal display panel by additionally providing one of the wafer 180 and the reflective brightness enhancement film 190 (Dual Brightness Enhancement Film, DBEF) in the form of white light.

諸如此類，在根據本發明之燈管裝置中，導光板係被去除，而側光式LED係被提供作為光源，而光係被導引以被樹脂層擴散、反射，進而使燈管裝置之厚度變薄，光源數目變少。同時，可由提供反射圖案、遮光圖案、以及氣隙單元之空氣區，並且調整上述元件以解決由光源數目變少所引起之亮度降低和均勻度問題，藉此來改善光學性質。And the like, in the lamp tube device according to the present invention, the light guide plate is removed, and the edge light type LED is provided as a light source, and the light system is guided to be diffused and reflected by the resin layer, thereby making the thickness of the lamp device Thinning, the number of light sources is reduced. At the same time, it is possible to improve the optical properties by providing the reflection pattern, the light-shielding pattern, and the air region of the air gap unit, and adjusting the above-described elements to solve the problem of brightness reduction and uniformity caused by the decrease in the number of light sources.
根據本發明，具有光學圖案之一光學圖案層係形成於接合材料被圖案化之處(黏著圖案層)，以提供一空氣區，並據此以去除出現在遮光圖案部分之局部亮區以及一暗區。另外，黏著材料與將被接合之元件間的燈管裝置可靠度係被確保，且在光學特性上並無顯著的差異；又，進一步地，使得元件間的精確校準調整變為可能的。According to the present invention, an optical pattern layer having an optical pattern is formed at a place where the bonding material is patterned (adhesive pattern layer) to provide an air region, and accordingly, to remove a portion of the bright region appearing in the portion of the light-shielding pattern and dark zone. In addition, the reliability of the lamp device between the adhesive material and the component to be joined is ensured, and there is no significant difference in optical characteristics; further, it is possible to make accurate calibration adjustment between components possible.
又，由圖案化一擴散片或使用獨立部件來包括空氣層之一氣隙單元係被提供，以增強光學特性如一燈管裝置擴散或光均勻度。Again, an air gap unit is provided by patterning a diffuser or using separate components to include an air layer to enhance optical characteristics such as lamp unit spread or light uniformity.
另外，在習知技藝中作為不可或缺的元件之一導光板係被去除，而使用一膜型樹脂層來減少光源數目、降低燈管裝置之整體厚度，進而增加產品設計之自由度。In addition, in the prior art, the light guide plate is removed as one of the indispensable components, and a film type resin layer is used to reduce the number of light sources and reduce the overall thickness of the lamp device, thereby increasing the degree of freedom in product design.
特別是，側發光式發光二極體係被裝設為一直下式，以在顯著地減少光源數量的同時，確保光學性質。去除導光板之燈管裝置係被應用於一可撓式顯示裝置，且進一步地將一擴散片，其係包含有具有一反射圖案之一反射膜，提供於一樹脂層以及空氣層之上，以確保穩定的發光特性。In particular, the side-emitting light-emitting diode system is installed as a constant type to ensure optical properties while significantly reducing the number of light sources.
