Description
Technical field
The present invention relates to a kind of display panel, and particularly relate to a kind of electrophoretic display panel.
Background technology
Along with plane shows the flourish of science and technology, user, except the performance of display panel is required to some extent, also has higher expectation to its apparent aesthetic feeling.In order to meet this demand of user, how display panel manufacturer has set about researching and developing the two-d display panel of narrow frame (slim-boarder).
Common two-d display panel comprises display panels (liquid crystal display panel), plasm display panel (plasma display panel), electrophoretic display panel (electrophoreticdisplay panel) etc.Taking electrophoretic display panel as example, its diagrammatic cross-section as shown in fig. 1.Please refer to Fig. 1, known electrophoretic display panel 100 (100 ') comprised first substrate 110, second substrate 120, be positioned at electrophoresis showed layer 130 between first substrate 110 and second substrate 120 and the frame glue 140 (140 ') around electrophoresis showed layer.The shared region of electrophoretic display panel 100 (100 ') can be divided into viewing area R (displayregion) and non-display area R ' (non-display region), wherein namely so-called rim area of non-display area R '.In Fig. 1, the electrophoretic display panel 100 of top has wider non-display area width W
b, the electrophoretic display panel 100 ' of below has narrower non-display area width W
b'.
When the non-display area width W of electrophoretic display panel 100
bbe reduced to narrower non-display area width W
b' time, although narrow frame electrophoretic display panel 100 ' can be implemented, the frame glue width W of electrophoretic display panel 100
salso must and then be reduced to narrower frame glue width W
s'.So, effect that the frame glue 140 ' of narrow frame electrophoretic display panel 100 ' stops aqueous vapor to enter electrophoresis showed layer 130, just be not as just like that good as wider frame glue 140.
