Title:
ELECTRONIC PAPER DISPLAY SCREEN AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/061555
Kind Code:
A1
Abstract:
An electronic paper display screen. The electronic paper display screen consists of a transparent electrode substrate (5), an upper layer transparent electrode (4), an electrophoretic display layer (8), and a pixel electrode (6) that are sequentially arranged from top to bottom, and is sealed by a waterproof glue (7). A conductive silver paste (9) is provided between the upper layer transparent electrode (4) and the pixel electrode (6), and is electrically connected to the upper layer transparent electrode (4) and the pixel electrode (6). The electrophoretic display layer (8) is a microcapsule or a microcup array, and may comprise two, three, or even more types of electrophoretic particles with different photoelectric properties. Black and white, single-color, double-color, multi-color, and true color display can be implemented. According to the display screen, a glue layer is not needed to bond the electrophoretic display layer and the pixel electrode, the production process is simplified, the display structure is simple, the thickness of the electrophoretic display layer is uniform and controllable, and the display effect is improved. Also disclosed is a manufacturing method for the electronic paper display screen.
