Title:
ELECTRONIC PAPER DISPLAY METHOD BASED ON LIQUID FLOW CONTROL
Document Type and Number:
WIPO Patent Application WO/2021/081684
Kind Code:
A1
Abstract:
An electronic paper display method based on liquid flow control. In electronic paper, a one-dimensional or two-dimensional matrix is formed by micro-structures, each micro-structure can be individually controlled, the deformation of the micro-structure is controlled and a change in the internal pressure distribution of the micro-structure is adjusted electronically, and a liquid flow direction is controlled. The electrically-controlled deformed micro-structure has a display cavity and a storage cavity, liquid of the display cavity can be viewed by a viewer, liquid of the storage cavity cannot be viewed by the viewer, and under the action of deformation of the micro-structure, the liquid flows between the display cavity and the storage cavity, wherein the liquid is a colored liquid. The volume of the liquid in the display cavity is adjusted by means of the deformation of the micro-structure, so as to adjust a color change in the micro-structure.
