Abstract
The present invention provides a double-layer stacked electronic paper drive structure, which is characterized in that it includes an upper layer of electronic paper, which is a cholesteric liquid crystal electronic paper screen, mainly composed of a front glass substrate, a bottom glass substrate, a first drive control chip, a first drive The first layer of FPC and the liquid crystal and plastic frame inside the LCD screen; the first drive control chip is located on the bottom glass substrate; the lower layer of electronic paper is electrophoretic electronic paper, mainly composed of electrophoretic electronic paper film, back glass substrate, second driver The control chip and the second driving layer FPC are composed; the second driving control chip is located on the back glass substrate; the test interface of the upper layer electronic paper/lower layer electronic paper directly or indirectly communicates with the double layer through the respective first driving layer FPC/second driving layer FPC The stacked electronic paper test system boards are connected together, and the surroundings of the double stacked electronic paper driving structure are sealed with a sealant. The invention has the advantages of increasing display effect, optimizing test interface, simplifying hardware structure, reducing cost and the like.
