Abstract

The invention discloses an electrowetting display substrate and a preparation method thereof, and an electrowetting display device having the substrate. The invention improves the preparation process of the electrowetting substrate and uses two supporting plates to coat in two steps. Then lamination transfer avoids the step of heat-treating the hydrophobic insulating layer to change its hydrophobic properties, maintains the original hydrophobic properties of the hydrophobic insulating layer, and improves the yield and life of the display device. At the same time, since the surface of the hydrophilic pixel wall material with low surface energy is coated with a hydrophobic insulating material, there is no problem of poor adhesion at all, which can overcome the poor binding force of coating the pixel wall material on the hydrophobic insulating layer in the traditional process , During use, gaps are likely to appear between the pixel wall and the hydrophobic insulating layer, resulting in a decrease in display quality.

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...
