1. An electronic ink screen, comprising a display module, a control module and a circuit module, wherein the display module comprises a plurality of pixel units and is configured to display by using electronic ink;
the control module is configured to convert a touch signal applied from outside into a change of electric signal of corresponding one or more of the pixel units through an electrode microstructure, so that a display state of the corresponding one or more of the pixel units is changed from an initial state; the electrode microstructure comprises sub-electrode microstructures in one-to-one correspondence with the pixel units, each of the sub-electrode microstructures comprises a first nano electrode and a second nano electrode which are made of different materials, and 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;
the circuit module is configured to supply power and control the control module to restore the display module to the initial state,
wherein the first nano electrode and second nano electrode are comb-shaped electrodes, and teeth of the first nano electrode and teeth of the second nano electrode are alternately arranged in a direction parallel to a display surface and partially overlap in a direction perpendicular to the display surface.
