Detailed Description
The following embodiments are provided for illustrative purposes only and are not intended to limit the scope of the present invention. The following description will be given with the same/similar reference numerals as used for the same/similar elements. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are referred to only in the direction of the attached drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
According to an embodiment of the present invention, an electronic paper package structure is provided, which includes a moisture barrier film bonded to a cover plate by a single adhesive layer, so as to increase the moisture barrier capability of the electronic paper package structure and reduce the cost. In one embodiment, the Water Vapor barrier capability is differentiated by the value of the Water Vapor Transmission Rate (WVTR). Preferably, the WVTR is less than 2-5 g/m at a temperature of 60 ℃ and a humidity of 90%2A day, or less than 1g/m2A day, or less than 0.5g/m2A day, or less than 0.1g/m2A day, or even less than 0.01g/m2The day is.
Referring to fig. 1 to 3, wherein fig. 1 is a schematic top view of an electronic paper package structure 100 according to an embodiment of the invention, fig. 2 is a schematic diagram of the electronic paper package structure 100 according to an embodiment of the invention in a cross section a-a, and fig. 3 is a schematic diagram of the electronic paper package structure 100 according to an embodiment of the invention in a cross section B-B.
In one embodiment, the electronic paper packaging structure 100 may include a substrate 110, an electronic ink layer 112, a cover plate 114, a moisture barrier film 116, an adhesive layer 117, and a molding compound 118.
The substrate 110 is, for example, a transparent glass or plastic substrate or an opaque substrate, and the upper surface 1102 of the substrate 110 is configured with a thin film transistor array (TFT array) or conductive graphite as a lower electrode plate. The cover plate 114 may include a transparent substrate 114a and a light-transmissive moisture barrier layer 114b, wherein the transparent substrate 114a is, for example, plastic or glass, and the material thereof may include a polymer plastic material such as polyethylene terephthalate (PET), Polystyrene (PS), Polycarbonate (PC), and the like. The material of the transparent moisture barrier layer 114b may be at least one of aluminum oxide (AlOx), silicon oxide, silicon nitride, titanium oxide, zirconium oxide, aluminum oxynitride, silicon oxynitride, and amorphous carbon. The moisture barrier ability of the light transmissive moisture barrier layer 114b is greater than that of the transparent substrate 114 a. In addition, the bottom surface 1142 of the cover plate 114 is provided with a transparent electrode layer 113, such as Indium Tin Oxide (ITO), as an upper electrode plate.
The electronic ink layer 112 is disposed on the substrate 110, and the electronic ink layer 112 is located between the substrate 110 and the cover plate 114. The electronic ink layer 112 may, for example, include millions of microcapsules (microcapsules) each containing electrophoretic particles, wherein the electrophoretic particles are negatively charged white and positively charged black particles suspended in a transparent liquid. When the electric field between the substrate 110 and the cover plate 114 is turned on, the electrophoretic particles move to the top of the microcapsule by the principle that the positive and negative charges attract each other, and a user can see the white or black particles on the corresponding block, thereby displaying a pixel pattern. In addition, the electronic ink layer 112 may also be a three-color or multi-color electronic ink layer to realize a full-color domain display effect, but the invention is not limited thereto. In addition, the electronic ink layer 112 may be a microcapsule (microcapsules) type electronic ink layer or a microcup type electronic ink layer.
In one embodiment, the moisture barrier film 116 is used to cover the substrate 110 and the electronic ink layer 112, so that the substrate 110 and the electronic ink layer 112 are sealed between the cover plate 114 and the moisture barrier film 116. In addition, the adhesive layer 117 is directly bonded between the cover plate 114 and the moisture barrier film 116, so as to reduce the moisture of the external environment entering through the adhesive layer 117, thereby increasing the moisture barrier capability of the electronic paper packaging structure 100. In one embodiment, the thickness of the adhesive layer 117 is about 25 μm, which is increased by 2 times (about 50 μm) compared to the conventional method of bonding two barrier films by using a double adhesive layer, so that more moisture in the external environment can enter through the double adhesive layer. Therefore, in the embodiment, the single adhesive layer 117 is directly bonded between the cover plate 114 and the moisture barrier film 116, which can save the cost and increase the moisture barrier capability of the electronic paper packaging structure 100.
In addition, in the embodiment, the single adhesive layer 117 is directly bonded between the cover plate 114 and the moisture barrier film 116, so the adhesive layer 117 is not bonded between the cover plate 114 and the electronic ink layer 112.
The moisture barrier film 116 includes a polymer such as epoxy resin, Polyurethane (PU), silica gel, or aluminum foil, or at least one material selected from aluminum oxide (AlOx), silicon oxide, silicon nitride, titanium oxide, zirconium oxide, aluminum oxynitride, silicon oxynitride, and amorphous carbon. In one embodiment, the moisture barrier film 116 covers the periphery of the substrate 110 and the electronic ink layer 112, wherein the electronic ink layer 112 is correspondingly displayed in a display area D1 of the cover plate 114, and the adhesive layer 117 is correspondingly bonded to a non-display area D2 of the cover plate 114.
In addition, referring to fig. 2, the side surface 1121 of the electronic ink layer 112 is substantially aligned with the side surface 1101 of the substrate 110 or the side surface 1101 of the substrate 110 protrudes a first distance relative to the side surface 1121 of the electronic ink layer 112, and the side surface 1121 of the electronic ink layer 112 is spaced a second distance (i.e., the width of the non-display area D2, for example, 2mm) relative to the side surface 1141 of the cover plate 114, wherein the second distance is greater than the first distance, so that the electronic ink layer 112 is hidden between the substrate 110 and the cover plate 114 to increase the moisture blocking distance and prevent the electronic ink layer 112 from being affected by moisture penetration of the external environment.
Referring to fig. 1 and 3, the substrate 110 may include a wire outlet portion 1103 for inputting/outputting a signal. The wire outlet portion 1103 extends out of the cover plate 114, and a lower surface 1142 of the cover plate 114, a side surface 1121 of the electronic ink layer 112, and an upper surface 1102 of the wire outlet portion 1103 define a groove 111. In the present embodiment, the encapsulant 118 can be filled in the recess 111 to prevent the electronic ink layer 112 from being affected by moisture penetration of the external environment. The molding compound 118 can be a thermoplastic, thermosetting, ultraviolet-curable, or room temperature-curable polymer curing compound, but the invention is not limited thereto.
In addition, since the encapsulant 118 is already sealed between the outgoing line portion 1103 of the substrate 110 and the cover plate 114, the adhesive layer 117 is not required to be bonded between the substrate 110 and the cover plate 114, so as to reduce the amount of the adhesive layer 117.
According to the electronic paper packaging structure disclosed by the embodiment of the invention, only one step of attaching the water-air-resistance diaphragm is needed, the manufacturing process is simplified, and the cost is lower. In addition, since the thickness of the adhesive layer is thin (e.g., less than 25 μm) and the gap between the cover plate and the moisture barrier film is small (e.g., less than 25 μm), moisture in the external environment is less likely to enter through the adhesive layer, thereby increasing the moisture barrier capability of the electronic paper package structure.
In summary, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
