An encapsulation layer 17 disposed on the second conductive layer 16. The cloth body 11 has a concave-convex surface 111 formed by staggered fibers. The material of the substrate layer 12 and the encapsulation layer 17 can be selected from the group consisting of fluorine-containing coatings, PVC coatings, PET coatings, and modified epoxy resins. The substrate layer 12 can provide a flat surface 121 for the first conductive layer 13. The material of the first conductive layer 13 can be selected from conductive metals such as gold, silver, copper, aluminum, and tin. The first dielectric layer 14 is formed by mixing a dielectric material and a colloid. The dielectric material can be selected from the group consisting of titanium dioxide (TiO 2 ), barium titanate (BaTiO 3 ), lead titanate (PbTiO 3 ), and barium titanate (SrTiO 3 ), as well as any combination of the foregoing. The electroluminescent layer 15 is composed of an electroluminescent material mixed with a colloid. The electroluminescent material is, for example, zinc sulfide.

此種電致發光布品除了該布體11外，該襯底層12、該第一導電層13、該第一介電層14、該電致發光層15、該第二導電層16及該封裝層17的硬度皆相當高。硬度高的缺點有二，其一是使用者穿戴在身上時，會有異物感或者因肌膚常時間受硬物擠壓而產生病變，其二便是該電致發光布品因為不可撓，而容易在使用者活動的過程中損壞。因此，習知的電致發光布品，僅能稱得上是將一個發光元件設置在布上而已，並未克服將電致發光技術與布結合的技術障礙，有待改善。 In addition to the cloth body 11, the substrate layer 12, the first conductive layer 13, the first dielectric layer 14, the electroluminescent layer 15, the second conductive layer 16, and the package The hardness of layer 17 is quite high. There are two disadvantages of high hardness. One is that when the user wears on the body, there will be a foreign body sensation or a skin lesion caused by the hardening of the skin at a time, and the second is that the electroluminescent fabric is inflexible. It is easy to damage during the user's activities. Therefore, the conventional electroluminescent fabric can only be said to be a light-emitting component disposed on the cloth, and does not overcome the technical obstacle of combining the electroluminescence technology with the cloth, and needs to be improved.

The second dielectric layer 23 can be omitted for implementation, and it is not necessary to include the second dielectric layer 23. This embodiment only provides an embodiment in which the illuminating effect is relatively stable and the illuminating efficiency is better.
該第一導電層24位於該第一聚氨酯層27與該第一介電層22間，並與該布體26及該電致發光層21相間隔。該第二導電層25位於該第二介電層23與該第二聚氨 酯層28間，與該第一介電層22分別位於該電致發光層21的兩相反側，並與該電致發光層21相間隔。該第一導電層24與該第二導電層25分別以奈米銀線構成。所述的奈米銀線，是在水溶液當中合成製得，具有微米等級的線長，以及奈米等級的線徑，並以塗布的方式設置在該第一聚氨酯層27上。該第一導電層24與該第二導電層25以奈米銀線構成的好處在於導電性良好，且較習知的金屬絲印具有更好的透光性。最重要的是，奈米銀線的柔軟度相當良好，在受有外力時，能配合其他各層形變，且不影響其導電能力及發光能力。 The first conductive layer 24 is located between the first polyurethane layer 27 and the first dielectric layer 22, and is spaced apart from the cloth body 26 and the electroluminescent layer 21. The second conductive layer 25 is located at the second dielectric layer 23 and the second polyamine The ester layers 28 are disposed on opposite sides of the electroluminescent layer 21 from the first dielectric layer 22, and are spaced apart from the electroluminescent layer 21. The first conductive layer 24 and the second conductive layer 25 are respectively formed of nano silver wires. The nano silver wire is obtained by synthesizing in an aqueous solution, has a line length of a micron order, and a wire diameter of a nanometer grade, and is disposed on the first polyurethane layer 27 in a coating manner. The advantage that the first conductive layer 24 and the second conductive layer 25 are formed of nano-silver lines is that the conductivity is good, and the known metal silk screen has better light transmittance. The most important thing is that the softness of the nano silver wire is quite good. When it is subjected to external force, it can be combined with other layers to deform without affecting its conductivity and luminous ability.
該布體26的種類無需特別限制，並具有一個因纖維交錯而形成且與該第一聚氨酯層27貼合的凹凸面261。 The type of the cloth body 26 is not particularly limited, and has an uneven surface 261 which is formed by interlacing fibers and which is bonded to the first polyurethane layer 27.
該第一聚氨酯層27設置在該凹凸面261上，並位於該布體26與該第一導電層24間，且包括一個與該布體26的該凹凸面261連接的連接面271，以及一個與該連接面271上下間隔且與該第一導電層24貼合的平整面272。該第二聚氨酯層28位於該第二導電層25上，並與該第二介電層23相間隔，且由該第二導電層25外緣往下延伸，以完整包覆各層外緣(圖未示意)。 The first polyurethane layer 27 is disposed on the concave-convex surface 261 and located between the cloth body 26 and the first conductive layer 24, and includes a connecting surface 271 connected to the concave-convex surface 261 of the cloth body 26, and a A flat surface 272 that is spaced apart from the connection surface 271 and that is bonded to the first conductive layer 24 . The second polyurethane layer 28 is located on the second conductive layer 25 and spaced apart from the second dielectric layer 23, and extends downward from the outer edge of the second conductive layer 25 to completely cover the outer edges of the layers (Fig. Not indicated).
該第一聚氨酯層27與該第二聚氨酯層28分別以聚氨酯材料構成。該第一聚氨酯層27與該第二聚氨酯層28所使用的聚氨酯材料，具有不錯的防水能力，使得本實施例在使用者戲水、潛水或游泳時，仍能正常發光而不會 因潤濕損壞。此一特性，使本實施例於水面下視線較不清楚的場合使用時，能因持續發光的特性，提供較佳的識別區分效果，利於水面下與他人互動的團體活動進行。 The first polyurethane layer 27 and the second polyurethane layer 28 are each made of a polyurethane material. The polyurethane material used in the first polyurethane layer 27 and the second polyurethane layer 28 has a good waterproof ability, so that the embodiment can still normally emit light when the user plays, dive or swim. Damaged by wetting. This feature enables the present embodiment to provide a better recognition and differentiation effect due to the characteristics of continuous illumination when the underwater view is less clear, which is advantageous for group activities that interact with others under the water surface.
該第一聚氨酯層27所提供的該平整面272，能解決該第一導電層24與該布體26的該凹凸面261不易結合的問題。此外，所述的聚氨酯材料具有如式(I)所示的官能基，親水性質良好，能使該第一聚氨酯層27與該第二聚氨酯層28分別與親水性的該第一導電層24及該第二導電層25良好地結合，並提升本實施例的穩定性與良率。 The flat surface 272 provided by the first polyurethane layer 27 can solve the problem that the first conductive layer 24 and the uneven surface 261 of the cloth body 26 are not easily bonded. In addition, the polyurethane material has a functional group represented by the formula (I) and has good hydrophilic properties, and the first polyurethane layer 27 and the second polyurethane layer 28 can be respectively hydrophilic with the first conductive layer 24 and The second conductive layer 25 is well bonded and enhances the stability and yield of the present embodiment.
本發明重要的一個技術特徵在於，採用聚氨酯材料的同時，也必須同時採用奈米銀線。否則，舉例來說，以聚氨酯材料搭配習知的ITO膜或ATO膜，縱使聚氨酯材料可撓，ITO膜或ATO膜在其他各層變形時也會因硬脆特性而碎裂，使得各層使用聚氨酯材料的構思徒勞無功。本案使用聚氨酯材料並搭配奈米銀線製得的成品經測試，可撓曲半徑≦5mm，能夠承受很大幅度的撓曲，且撓曲次數300次後發光穩定度仍≧80%，耐撓曲的效果相當卓越。 An important technical feature of the present invention is that while a polyurethane material is used, it is also necessary to use a nano silver wire at the same time. Otherwise, for example, a polyurethane material is matched with a conventional ITO film or an ATO film. Even if the polyurethane material is flexible, the ITO film or the ATO film may be broken due to hard and brittle characteristics when deformed in other layers, so that each layer uses a polyurethane material. The idea is futile. The case is made of polyurethane material and finished with nano silver wire. It can be flexed to a radius of mm5mm and can withstand a large degree of deflection. After 300 times of deflection, the luminous stability is still 80%. The effect of the song is quite excellent.
綜上所述，本發明電致發光布品的功效在於：各層間改以柔軟且可撓的聚氨酯材料為主體，且該第一導電層與該第二導電層也都以可撓的奈米銀線取代硬且脆的ITO或ATO薄膜，大大提升整體柔軟性，故能達成本案可 撓且便於穿戴的目的。此外，各層所使用的聚氨酯材料的防水效果佳，能使本發明即使位於水面下或接觸到大量的水，也不會潤濕損壞。 In summary, the effect of the electroluminescent fabric of the present invention is that the layers are changed with a flexible and flexible polyurethane material, and the first conductive layer and the second conductive layer are also flexible nanometers. The silver wire replaces the hard and brittle ITO or ATO film, which greatly enhances the overall softness, so the case can be achieved. Scratching and easy to wear. In addition, the polyurethane material used in each layer has a good water-repellent effect, so that the present invention does not wet and damage even if it is under the surface of the water or is in contact with a large amount of water.
惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。 However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
