Electrophoretic display device and method for manufacturing the same |
摘要 |
Embodiments of the present invention relates to an electrophoretic display (EPD) device and a method for manufacturing the EPD device. The EPD device includes an electrophoretic substrate and a drive substrate arranged opposite to each other and a plurality of microcups disposed between the electrophoretic substrate and the drive substrate, each microcup includes a cup body for defining an accommodating space; a thickness of the cup body on one side of the microcup closer to the electrophoretic substrate is less than a thickness of the cup body on one side of the microcup closer to the drive substrate; and a cup surface of the microcup is a cambered surface which is away from a vertical central axis of the microcup and concave towards the cup body. |

1. An electrophoretic display (EPD) device, comprising an electrophoretic substrate and a drive substrate arranged opposite to each other and a plurality of microcups disposed between the electrophoretic substrate and the drive substrate,
wherein each microcup includes a cup body for defining an accommodating space; a thickness of the cup body on one side of the microcup closer to the electrophoretic substrate is less than a thickness of the cup body on one side of the microcup closer to the drive substrate; and a cup surface of the microcup is a cambered surface which is away from a vertical central axis of the microcup and concave towards the cup body, wherein the cup body is formed by a plurality of partition walls arranged in an array; upper surfaces and lower surfaces of the partition walls are parallel to each other; and both the two side-walls of the partition wall are cambered surfaces, and a height of the partition walls is ranged from 1 to 10 micrometers; and a radius of the cambered surface of the two side-walls of the partition walls is ranged from 4 to 10 micrometers. |
