Abstract
An electronic paper display screen and a manufacturing method thereof belongs to the field of electronic display. The electronic paper display screen of the present invention eliminates the conventional adhesive layer, and the electrophoretic display layer and the pixel electrode are bonded without the adhesive layer. The electronic paper display screen of the present invention has a simplified production process, a simple display structure, a uniform and controllable thickness of the electrophoretic display layer, and improved display effects. The traditional adhesive layer is removed from the structure of the electronic paper display screen. The present invention is applicable to the electronic paper with a microcapsule or micro-cup structure, wherein the microcapsule or the micro-cup can include two, three or more kinds of electrophoretic particles having different photoelectric properties.
