A LIGHT GUIDE PLATE FOR AN ELECTRONIC PAPER DISPLAY, AND THE ELECTRONIC PAPER DISPLAY |
摘要 |
The present invention provides a light guide plate (30) for an electronic paper display and the electronic paper display. The light guide plate (30) is arranged above a display surface of an electrophoretic display module (10), and it comprises a main body, wherein a tooth-shaped pattern is arranged on an in-light surface (33) of the main body. The electrophoretic display module (10) comprises a microcapsule electrophoretic display module or a microcup electrophoretic display module. The tooth-shaped pattern is formed by a plurality of arc-shaped projections (331), arc-shaped recesses (332), angle-shaped projections, or angle-shaped recesses (333). The tooth-shaped pattern provides the in-light surface (33) with in-light angles of multiple directions, which greatly diffuse light beam that enters the light guide plate (30), thereby avoiding appearance of a dark area (B1, B2, B3) in an in-light position of the display area (90), so as to provide a more evenly distributed luminance in the display area (90) and thus provides a better lighting effect. |
