New description: [New technical field] The type of lightning is a kind of display module, and especially the display module composed of electric ice display components and light-emitting diodes. [Prior Art], J;:r;;:l^Y"E'PAPER) i:mm), Xianhe content self-holding and non-self-luminous. Electronic; ί: The electrical characteristics used in some message display devices will be: for example, the parent communication display device, etc., if the battery is used without the need for other external power supply; the cost of erection is not large. This is a traditional LED display; the proposed superiority of the 'electrophoretic display element is a big advantage 2, which has almost no load on the installation site. It is also the largest display device composed of its swimming display components. The weakness is the source of another = at night, it is useless, if you use other optical components to form the heart and lose the advantages of its famous name, so the current location of the device used by electrophoresis display, will not be part of limit. The characteristics of the display elements are that the display elements of the electrophoretic display elements are combined with the device, and the light is illuminated by the light-emitting diode during electrophoresis in the daytime. The brightness only needs to be: the display content of the piece. Due to the 1/10 of the day required for a night-emitting diode, the number of LEDs and related parts only need to be a full-emitting diode display compared to the full-length LED as the M439816 display. /10, the difference is very large, and at night, the light-emitting diode only needs to illuminate the part to be displayed, and the illuminating electrophoretic display element can be saved 50%~80% compared with the external light source. Electricity. Since the light-emitting diode only illuminates the area displayed by the electrophoretic display element, the light-emitting diode of the non-display point does not illuminate, and the high contrast ratio of the mutual formation of the light-emitting diode can save the power consumption of the light-emitting diode. Compared with the traditional light-emitting diode display, the display device composed of the electrophoretic display element and the light-emitting diode φ body only needs the number of the light-emitting diodes of the conventional light-emitting diode lamp and the related parts, and the weight thereof is also It will be much lighter. [New content] Therefore, one of the objects of the present invention is to provide a display module that is invaded by waterproof gas. According to the above object of the present invention, a display module is provided which comprises a circuit board, a plurality of electrophoretic display pixel units and a transparent paint layer. The circuit board has a plurality of light emitting diodes located thereon. The complex electrophoretic display pixel unit covers the circuit board, and each of the electrophoretic display unit has a through hole for each corresponding light emitting diode to traverse and protrude. A layer of clear coating is applied over the electrophoretic display element units, and the transparent coating layer seals at least the through holes of each of the electrophoretic display unit. According to another embodiment of the present invention, the transparent paint layer covers a portion of each of the light-emitting diodes protruding from the through hole. According to another embodiment of the present invention, the transparent coating layer is a polymer coating layer. 0 M439816 According to another embodiment of the present invention, the transparent coating layer is made of epoxy resin, silicone rubber, styrofoam coating or varnish. According to another embodiment of the present invention, each of the electrophoretic display unit includes an upper transparent electrode layer, a lower electrode layer, and an electronic ink capsule layer. The electron ink capsule layer is located between the upper transparent electrode layer and the lower electrode layer. According to another embodiment of the invention, the clear coating layer covers the bottom surface of the circuit board. It can be seen from the above that the display module of the present invention is used to seal the through holes of each electrophoretic display unit by using a transparent coating layer, so that the outside of the water vapor and the like are not invaded, thereby continuing the service life of the display module. In addition, the clear coating layer does not affect the display performance of the electrophoretic display unit and the light-emitting diode unit, and the thickness and weight of the display module are not affected. [Comprehensive Mode] Please refer to Figs. 1 and 2 together. Fig. 1 is a cross-sectional view showing a display module in accordance with an embodiment of the present invention. Figure 2 is a top view of the display module of Figure 1. The display module 100 mainly includes an electrophoretic display unit, a light emitting diode unit and a sealed casing 112. The LED unit includes a circuit board 108 and a plurality of LEDs 110 mounted on the circuit board 108. The complex electrophoretic display unit 102 covers the circuit board 108, and each electrophoretic display unit 101 has a through hole 110a for each corresponding light-emitting diode 110 to traverse and protrude. The display module 100 displays the message by electrophoresis display of the pixel unit 109 during the daytime, and illuminates the electrophoretic display element unit 109 by the light of the light-emitting diode 110 at night. In this embodiment, since each of the electrophoretic display element units 109 needs to be paired with one of the light-emitting diodes 110, 5 M439816, it is necessary to dig a through hole 110a in each of the electrophoretic display pixel units 109 for each corresponding light. The diode 110 passes through and protrudes. Each of the electrophoretic display unit 109 includes an upper transparent electrode layer 104, a lower electrode layer 106, and an electronic ink capsule layer 102. The electronic ink capsule layer 102 is located between the upper transparent electrode layer 104 and the lower electrode layer 106. Since the through hole 110a penetrates the upper transparent electrode layer 104, the lower electrode layer 106, and an electronic ink capsule layer 102, and the display module 100 is mainly used for the outdoor kanban, the electronic ink capsule layer 102 is easily accessible from the through hole due to the external moisture. 110a invasion caused the use of life φ life can not last long. In order to extend the service life of the electronic ink capsule layer 102, a transparent sealed casing 112 is used to seal the entire electrophoretic display unit and the light-emitting diode unit so that external moisture can be isolated by the sealed casing 112. However, the disadvantage of using the sealed housing 112 is that the thickness and weight of the display module are excessively increased. When the area of the display module is large, the weight of the display module is greatly increased, and the electrophoretic display unit is lightly damaged. Thin features. In order to overcome the above disadvantages, the following preferred solutions are provided. φ Referring to FIG. 3, a cross-sectional view of a display module in accordance with another embodiment of the present invention is shown. The display module 200 includes an electrophoretic display unit, a light emitting diode unit, and a clear paint layer. The clear coating layer provides a function equivalent to that provided by the sealed housing 112 described above, but does not cause the disadvantage of excessively increasing the thickness and weight of the display module. The light emitting diode unit includes a circuit board 208 and a plurality of light emitting diodes 210 mounted thereon. The plurality of electrophoretic display pixel units are overlaid on the circuit board 208, and each of the electrophoretic display elements has a through hole 210a for each corresponding light emitting diode 210 to pass through and protrude. Each of the electrophoretic display unit includes an upper transparent electrode layer 6 2〇4, a lower electrode layer, and a capsule layer disposed on the upper transparent electrode layer. The electronic ink is passed through the through hole 21 〇a through the through-dip/=1 layer 206. The main function of the material layer 2G4 and the lower electrode layer is to apply at least the through hole 210a of each electrophoresis, so that the water and gas are not invaded. In this embodiment, 'The clear coating layer 212a is heated in a vacuum to form the coating.

/冗積於上透明電極層2〇4的表面、填入通孔21 〇3内、覆蓋 於母一發光一極體210凸出於通孔21〇a外的部份，甚至透 明塗料層212b還可覆蓋電路板208的底面，而達到對顯示 模組200完全的密封。由於透明塗料層是以沉積方式塗佈 於顯示模組的表面，因此厚度可以非常薄，不致於影響電 泳顯示單元和發光二極體單元的顯示效能，對顯示模組之 厚度及重量的增加更是微不足道。在本實施例中，透明塗 料層可以是高分子塗料等能夠經加熱成氣態而沉積於物體 表面的材料。 請參照第4圖，其繪示依照本發明再一實施例的一種 顯示模組的剖面圖。顯示模組300包含電泳顯示單元、發 光二極體單元及透明塗料層。透明塗料層31.2提供的功能 相當於上述透明塗料層212a所提供的功能，但以不同方式 塗佈於顯示模組的表面。發光二極體單元包含一電路板3 0 8 及裝設於其上的複數發光二極體310。複數電泳顯示畫素 單元覆蓋於電路板308上，且每一電泳顯示畫素單元具有 一通孔310a，供每一對應的發光二極體310穿越並凸出。 每一電泳顯示畫素單元包含一上透明電極層304、一下電 M439816/ redundantly accumulated on the surface of the upper transparent electrode layer 2〇4, filled in the through hole 21 〇3, covering the portion of the mother-emitting one-pole body 210 protruding from the through hole 21〇a, even the clear coating layer 212b The bottom surface of the circuit board 208 can also be covered to achieve a complete sealing of the display module 200. Since the transparent coating layer is applied to the surface of the display module by deposition, the thickness can be very thin, which does not affect the display performance of the electrophoretic display unit and the light emitting diode unit, and the thickness and weight of the display module are increased. It is trivial. In the present embodiment, the transparent coating layer may be a material such as a polymer coating which can be heated to a gaseous state and deposited on the surface of the object. Referring to FIG. 4, a cross-sectional view of a display module in accordance with still another embodiment of the present invention is shown. The display module 300 includes an electrophoretic display unit, a light emitting diode unit, and a clear paint layer. The clear coating layer 31.2 provides a function equivalent to that provided by the clear coating layer 212a described above, but is applied to the surface of the display module in a different manner. The light emitting diode unit includes a circuit board 308 and a plurality of light emitting diodes 310 mounted thereon.

極層306以及一電子墨水囊層302。電子墨水囊層302位 於上透明電極層304與下電極層306之間。由於通孔310a 係貫穿上透明電極層304、一下電極層306以及一電子墨 水囊層302，造成外界水氣很容易從通孔310a入侵。透明 塗料層312a的主要功能仍是至少密封每一電泳顯示晝素 單元之通孔310a，讓水氣無從入侵。在本實施例中，透明 塗料層312是直接塗佈於上透明電極層304的表面而將顯 示模組300上的通孔310a的缝隙完全密封，讓水氣無從入 侵。透明塗料層亦可塗佈於每一發光二極體310凸出於通 孔310a外的部份（未繪示於圖面），甚至塗佈於電路板308 的底面（未繪示於圖面），而達到對顯示模組300完全的密 封。由於透明塗料層312並非以沉積方式塗佈於顯示模組 的表面，因此其厚度較透明塗料層212a厚，但也不致於影 響電泳顯示單元和發光二極體單元的顯示效能，對顯示模 組之厚度及重量的增加也不致於影響。在本實施例中，透 明塗料層可以是環氧樹脂、矽膠、保麗塗料、凡立水等方 便塗佈於物體表面的材料。 由上述本新型實施方式可知，應用本新型之顯示模 組，利用透明塗料層密封每一電泳顯示晝素單元之通孔， 使得水氣等外界無從入侵，藉以延續顯示模組的使用壽 命。此外，透明塗料層不致於影響電泳顯示單元和發光二 極體單元的顯示效能，對顯示模組之厚度及重量的增加也 不致於影響。 雖然本新型已以實施方式揭露如上，然其並非用以限 定本新型，任何熟習此技藝者，在不脫離本新型之精神和 8 夕◦丄ϋ [圖式簡單說明】 為讓本新型之上述和其他目的、特徵、優點與實施例 月匕更明顯易懂’所附圖式之說明如下： 第1圖係繪示依照本發明一實施例的一種顯示模組的 剖面圖。 . 、 第2圖係繪示第1圖之顯示模組的上視圖。 第3圖係繪示依照本發明另一實施例的一種顯示模組 的剖面圖。 第4圖係繪示依照本發明再一實施例的一種顯示模組 的剖面圖。 【主要元件符號說明】 100顯示模組 102電子墨水囊層 104上透明電極層 106下電極層 1〇8電路板 109電泳顯示晝素單元 110發光二極體 110a通孔 112密封殼體 M439816 200顯示模組 202電子墨水囊層 204上透明電極層 206下電極層 208電路板 210發光二極體 210a通孔 212a透明塗料層 212b透明塗料層 300顯示模組 302電子墨水囊層 304上透明電極層 306下電極層 308電路板 310發光二極體 310a通孔 312透明塗料層The pole layer 306 and an electronic ink capsule layer 302. The electronic ink capsule layer 302 is located between the upper transparent electrode layer 304 and the lower electrode layer 306. Since the through hole 310a penetrates through the upper transparent electrode layer 304, the lower electrode layer 306, and an electronic ink reservoir layer 302, external moisture easily invades from the through hole 310a. The main function of the transparent coating layer 312a is still to at least seal the through holes 310a of each electrophoretic display unit, so that water and gas are not invaded. In the present embodiment, the transparent coating layer 312 is directly applied to the surface of the upper transparent electrode layer 304 to completely seal the gap of the through hole 310a on the display module 300, so that moisture and water are not invaded. The transparent paint layer may also be applied to a portion of each of the light-emitting diodes 310 protruding from the through hole 310a (not shown), or even applied to the bottom surface of the circuit board 308 (not shown in the drawing). ), to achieve a complete seal of the display module 300. Since the transparent coating layer 312 is not deposited on the surface of the display module in a deposition manner, the thickness thereof is thicker than the transparent coating layer 212a, but does not affect the display performance of the electrophoretic display unit and the light emitting diode unit, and the display module The increase in thickness and weight does not affect it. In this embodiment, the transparent coating layer may be an epoxy resin, silicone rubber, styrofoam coating, varnish or the like which is easily applied to the surface of the object. According to the above-mentioned novel embodiment, the display module of the present invention is used to seal the through holes of each electrophoretic display element by using a transparent paint layer, so that the outside world such as moisture and water is not invaded, thereby continuing the life of the display module. In addition, the transparent coating layer does not affect the display performance of the electrophoretic display unit and the light emitting diode unit, and the thickness and weight of the display module are not affected.
