Abstract

The invention discloses an electrowetting display substrate, a manufacturing method for the electrowetting display substrate, and an electrowetting display device. The manufacturing method for the electrowetting display substrate is characterized in that the manufacturing process of the electrowetting display substrate is improved, two support plates are adopted and coated in two steps, then fitting and transferring are carried out, and the step of carrying out heat treatment on a hydrophobic insulation layer to change the hydrophobic property is eliminated, so that the original hydrophobic property of the hydrophobic insulation layer is retained, the yield of a display device is improved and the service life of the display device is prolonged; meanwhile, the surface of a hydrophilic pixel wall material with low surface energy is coated with a hydrophilic insulation material, so that the problem of poor adhesion is thoroughly overcome; the defects of poor adhesion caused by coating the hydrophobic insulation layer with the pixel wall material, high possibility of forming a gap between the pixel wall and the hydrophobic insulation layer in the using process and the reduction of the display quality in the conventional process can be overcome.

Description

technical field [0001] The present invention relates to the field of electrowetting display technology; in particular, it relates to an electrowetting display substrate and a preparation method thereof, and a device including the electrowetting display substrate. Background technique [0002] Electrowetting display devices generally include a fluid chamber and an electrode structure, where the fluid chamber contains a non-conductive first fluid (alkane, silicone oil), a conductive second fluid (water or salt solution, etc.), and the fluids are in contact with each other and cannot be mixed. dissolve. For example, patent CN 102792207A describes an electrowetting display device, which includes two substrates, one of which is provided with a wall pattern, that is, a pixel wall, and the pixel wall is photoetched by a photoresist material (such as SU8). According to the process, the area formed by the pixel grid surrounded by the pixel wall is the display area, and the electrowe...
