Technical Field

The utility model relates to an electronic paper packaging structure, concretely relates to colored electronic paper packaging structure.

Background

The electronic paper is a novel display material based on the electrophoresis principle, can not hurt eyes as common paper, has the characteristics of ultralow energy consumption, thinness like paper, flexibility, and the definition of a similar book, and has a display effect similar to that of a real paper book; at present, the packaging of electronic paper on the market is basically of two structures, namely a hot-pressing structure and a glue-dispensing edge-sealing structure; the hot pressing mode is a hot plate or hot roller pressing mode, and has the characteristics of simple process and low cost; certain bubble cavities can exist, and the smaller bubble cavities can not have any influence on the reliability of the electronic paper. The glue dispensing and edge sealing type is to dispense a circle of edge sealing glue around the electronic paper to achieve the purpose of preventing water vapor from entering, but the glue dispensing process is complex, the glue demand is large, and the glue curing process is added, so the required cost is high. In the existing color electronic paper, a layer of color photoresist is basically arranged on black and white electronic paper to form a light filtering and color developing layer, and for example, a color film substrate and an electronic paper body are directly attached together as in patent No. 2011104468712. Because the thickness is higher due to direct pasting and larger break difference exists between the structure and the bottom plate, if a hot-pressing packaging type is adopted, the bubble cavity is enlarged, and the reliability of the electronic paper is influenced, so the structure usually adopts a glue-dispensing edge-sealing mode to avoid forming the cavity; but because the distance of the offset is increased, the glue amount required by glue dispensing and edge sealing is greatly increased, and the glue curing equipment is added, so that the process is complex and the cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a colored electronic paper packaging structure of edge for echelonment structure has simplified technology, has improved production efficiency, the cost is reduced.

The utility model adopts the technical proposal that: a color electronic paper packaging structure comprises a driving substrate, an electrophoretic display layer, a color development layer and a protective layer which are sequentially arranged from bottom to top and are arranged in an array manner; the color development layer is matched with the electrophoresis display layer in shape, the size of the color development layer is slightly smaller than that of the electrophoresis display layer, and the driving substrate, the electrophoresis display layer and the edge of the color development layer form a stepped structure; and pressing and packaging by a hot plate or a hot roller.

Further, the edge point edge sealing glue of the electrophoresis display layer forms an edge sealing glue layer, and the glue is pressed and packaged through a hot plate or a hot pressing roller after being cured.

Furthermore, after the electrophoresis display layer is pressed and packaged by a hot plate or a hot roller, the edge of the electrophoresis display layer is provided with waterproof sealant to form a waterproof sealing adhesive layer.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a color electronic paper packaging structure includes a driving substrate 1, an electrophoretic display layer 2, a color development layer 3, and a protection layer 7, which are sequentially arranged from bottom to top and are arranged in an array; the color development layer 3 is matched with the electrophoresis display layer 2 in shape, the size of the color development layer 3 is slightly smaller than that of the electrophoresis display layer 2, and the edges of the driving substrate 1, the electrophoresis display layer 2 and the color development layer 3 form a step-shaped structure; and pressing and packaging by a hot plate or a hot roller. The electrophoretic display layer 2 is black-and-white electronic paper and is directly attached to the array driving substrate 1; the color development layer 3 can be made of functional materials with the functions of filtering, developing or guiding light, and the size of the color development layer is required to be slightly smaller than that of the electronic paper, so that the color development layer is convenient to be attached to the electronic paper to form a step-shaped structure at the edge.

The protective layer 7 mainly functions to protect the electronic paper and can be made of materials with good waterproof and ultraviolet-proof effects; the hot plate or the hot roller is convenient to use for pressing, the edge sealing effect which is the same with the hot pressing effect of the common black and white electronic paper is achieved, and as shown in figure 1, most of use requirements are met.

furthermore, in order to achieve a better appearance effect, a circle of edge sealing glue can be firstly dispensed on the periphery of the electronic paper, the dispensing height is preferably not more than the electronic paper body, and the electronic paper is pressed in a hot pressing/hot plate mode after the glue is cured, so that the use of the edge sealing glue can be reduced, and the cost is saved; edge sealing glue is dispensed on the edge of the electrophoretic display layer 2 to form an edge sealing glue layer 5, and the glue is pressed and packaged through a hot plate or a hot pressing roller after being cured; resulting in the structure shown in fig. 2.

Further, in order to achieve a narrower edge sealing effect, a stepped structure is formed by pressing and packaging through a hot plate or a hot roller, and then waterproof sealant is dispensed at the edge of the electrophoretic display layer 2 to form a waterproof sealant layer 6. The commonly used packaging process is improved from coating the color development layer and the periphery of the electronic paper with the edge sealing glue to coating the periphery of the electronic paper only, so that the section difference is effectively reduced, the use amount of the edge sealing glue is reduced, and the cost is saved.

In the utility model, the color development layer 3 is slightly smaller than the body of the electrophoresis display layer 2, and a ladder-shaped structure is formed at the edge of the electrophoresis display layer 2; packaging the electronic paper by adopting a hot-pressing packaging mode; the packaging structure with the structure simplifies the preparation process, improves the production efficiency and reduces the cost.
