Abstract

The invention discloses a manufacturing method of an electric moistening element. The manufacturing method includes the steps of firstly, providing liquid-state ink, freezing the ink into a crystal state, and grinding the crystal-state ink into powder; secondly, providing a first fluid, mixing the first fluid with the powdered ink obtained in the first step, and coating a substrate below with the mixture along the surface of the substrate, wherein the substrate comprises a pixel wall, and the pixel wall comprises a plurality of pixel cells; the first fluid comprises a solvent, and the solvent is optional one of C6-C16 alkanes, cycloalkanes, aromatic series, aliphatic series or silicone oil; thirdly, filling the pixel cells with the powdered ink obtained in the first step; fourthly, providing an electrolyte solution with the temperature being 80-120 DEG C, and soaking the substrate after the filling into the electrolyte solution for 1-2 hours so as to allow the substrate to absorb the electrolyte solution; fifthly, taking out the substrate, and drying.

Description

technical field [0001] The invention relates to a method for manufacturing a substrate, in particular to a method for manufacturing an electrowetting element. Background technique [0002] In recent years, attention has been paid to electrowetting elements utilizing the electrowetting effect. Usually, the electrowetting element is filled with a high surface energy liquid with a relatively high surface energy and a low surface energy liquid with a relatively low surface energy that do not mix with each other between a pair of substrates, and one of the substrates has an electrode layer and a formed electrode layer on the surface. The hydrophobic intermediate layer on the surface of the electrode layer. The electrowetting element has the following characteristics: if a voltage is applied between the hydrophilic liquid and the electrode layer through the hydrophobic intermediate layer, the hydrophilic liquid is drawn to the hydrophobic intermediate layer, and the hydrophilic l...
