Embodiment Construction

[0030] Such as Figure 2A As shown, the electrophoretic display structure of the present invention includes a substrate 100 , a driving layer 110 , an electrophoretic display layer 200 , a protective layer 300 , a first sealing material 500 and a second sealing material 700 . The driving layer 110 is disposed on the substrate 100 , and the electrophoretic display layer 200 is disposed on the driving layer 110 . The substrate 100 described here preferably refers to glass, organic film, flexible film or other suitable materials. The electrophoretic display layer 200 has a plurality of electrophoretic display elements 250 and a water blocking layer 210 , wherein the water blocking layer 210 is disposed on the electrophoretic display elements 250 . The water blocking layer 210 preferably has the same size and area as the electrophoretic display layer 200 , and the two are preferably stacked in an aligned manner. However in Figure 2B In the illustrated embodiment, the size of t...

Abstract

The invention relates to an electrophoresis display structure, comprising a base plate, a driving layer, an electrophoresis display layer, a protective layer, a first glue sealing material and a second glue sealing material, wherein the driving layer is arranged on the base plate, and the electrophoresis display layer is arranged on the driving layer; the electrophoresis display layer is provided with a plurality of electrophoresis display assemblies and waterproof layers, and the waterproof layers are arranged on the electrophoresis display assemblies, the protective layer is arranged on the waterproof layer, the first glue sealing material is arranged between the driving layer and the protective layer and is filled in a side edge of the electrophoresis display layer. The second glue sealing material is covered at the outer side of the first glue sealing material and is respectively connected with the driving layer and the protective layer. The liquid viscosity of the first glue sealing material is lower than that of the second glue sealing material.

Description

【Technical field】 [0001] The present invention relates to a light, thin, soft and portable flat panel display (FlatPanel Display), and in particular to an electrophoretic display structure applied to an electronic paper display (Electronic Paper Display) using electrophoretic display (EPD) technology. 【Background technique】 [0002] E-books have both the display quality of traditional paper and the advantages of arbitrary bending mechanical properties, combined with the characteristics of digital electronic media that can update information in real time. Therefore, Electronic Paper Displays (Electronic Paper Displays) are gradually accepted by the public and will replace transmission paper in the future. [0003] figure 1 It is a schematic diagram of the existing electrophoretic display technology. A conventional electrophoretic display structure includes a substrate 10 , an electrophoretic display layer 30 , a protective layer 40 and a plastic frame 50 . Such as figure 1...
