AI Technical Summary

Problems solved by technology

However, when the hydrophobicity of the hydrophobic layer is weakened, the area where water directly contacts the hydrophobic layer increases greatly, which may cause leakage.
In this way, the components under the hydrophobic layer will be damaged, and the reliability of the electrowetting display unit will be poor.

Abstract

The invention relates to an electrowetting display unit which comprises a first substrate, a second substrate, a retaining wall, an electrowetting display medium, a pixel electrode, a counter electrode, a hydrophobic layer and a multi-layer insulating structure. The second substrate is opposite to the first substrate. The retaining wall is configured between the first substrate and the second substrate. The electrowetting display medium is surrounded by the retaining wall, the first substrate and the second substrate. The pixel electrode is configured between the second substrate and the electrowetting display medium. The counter electrode is configured between the first substrate and the electrowetting display medium. The hydrophobic layer is configured between the pixel electrode and the electrowetting display medium. The multi-layer insulating structure is configured between the pixel electrode and the hydrophobic layer, wherein the multi-layer insulating structure comprises at least one first atomic-layer deposition layer.

Description

technical field [0001] The invention relates to a display element, in particular to an electrowetting display unit. Background technique [0002] With the development and progress of science and technology, the mechanism of electrowetting phenomenon has been understood. The phenomenon of electrowetting mainly utilizes the characteristic that when the applied voltage between two liquids changes, the surface tension also changes, which causes the liquid to move to achieve the desired liquid distribution state. [0003] Electrowetting technology can distribute two liquids of different colors in different ways under the same space, so it can be applied to displays. In detail, the electrowetting display unit has a hydrophobic layer, and the two liquids can be oil and water with different colors. When a voltage is applied to the electrowetting display unit, a charge distribution occurs on the surface of the hydrophobic layer. At this time, the affinity of the hydrophobic layer f...
