Abstract
An electronic ink screen and a method for manufacturing the same are provided. The electronic ink screen includes: a display module including pixel units configured to display by using electronic ink; and a control module configured to convert a touch signal applied from outside into a change of electric signal of corresponding one or more pixel units through an electrode microstructure, so that a display state of the corresponding one or more pixel units is changed from an initial state; the electrode microstructure includes sub-electrode microstructures, each sub-electrode microstructure includes a first nano electrode and a second nano electrode which are made of different materials, the first nano electrode and the second nano electrode are arranged at intervals and configured to be in mutual friction contact in response to that the touch signal applied from the outside is received, so as to generate charge transferring.
