technical field

The present invention relates to a display device, in particular to a display device capable of reducing air bubbles in the sealant. the

Background technique

Reading text or pictures recorded on paper is the most familiar reading method for human beings. With the advancement of printing technology and the reduction of printing costs, paper has been widely used as a recording medium for various data in recent centuries. However, with the advancement of display technology, paper is likely to be replaced by various displays in the near future, especially electrophoretic displays (electrophoretic displays, EPDs). Since the electrophoretic display is light, thin, flexible and easy to carry like paper, it can be expected to be used to realize the application of electronic paper or e-book, replacing paper as a data recording medium. the

Please refer to FIG. 1 and FIG. 2 , which are schematic diagrams of conventional electrophoretic displays, wherein FIG. 1 is a cross-sectional view along the line AA' in FIG. 2 . The conventional electrophoretic display 100 includes a backplane 102 , a frontplane 104 and an electronic ink material layer 106 between the backplane 102 and the frontplane 104 . Since the optical properties of the electronic ink material layer 106 are easily affected by water vapor, the conventional electrophoretic display 100 is usually provided with a barrier layer 108 above the front plate 104 in the subsequent packaging process, and on the front plate 104, A frame glue 110 is formed around the backplane 102 and the barrier layer 108 to prevent outside moisture from invading the electronic ink material layer 106 . the

In addition, as shown in FIG. 1 and FIG. 2 (in order to clearly show the relationship between the components, the sealant 110 is not shown in FIG. ₂ ), the common electrode ( not shown), the existing electrophoretic display 100 also has a silver glue 114, which is arranged on a front plate ear 112 protruding from the front plate 104, and usually the barrier layer 108 also has a corresponding barrier layer here ear 113 . However, due to poor design of the existing front panel ear 112 and barrier layer ear 113 , the sealant 110 is likely to cover air bubbles during the subsequent encapsulation process of forming the sealant 110 , resulting in defects. Please refer to FIG. 3 , which is a partially enlarged view of area B in FIG. 2 . As shown in Figure 3, since the front plate ear 112 and the barrier layer ear 113 are designed to be at right angles, there may be a situation where the distance at the bend is not uniform and the gap is too large, for example, the bevel at the bend The distance d1 will be greater than the distance d2 between the two parallel sides. Such a situation makes the sealant 110 only able to be formed at the distance d2 inward of the barrier layer 108 when it is formed, but the sealant 110 cannot completely reach the distance d1 inward of the barrier layer 108 and fill up the bend. Therefore, after the sealant 110 is cured, air bubbles 116 are generated at the bend. On the one hand, the air bubbles 116 will reduce the water resistance of the product and affect the reliability of the overall product; Holes are formed on the frame glue 110 . The above situations will seriously affect the display quality of the electrophoretic display 100 , and become an urgent problem to be solved at present.
