A method for preparing an electrowetting display support plate (), comprising the following steps: preparing a substrate () having an electrode layer; preparing a hydrophobic insulating layer () and pixel walls () on the substrate () having an electrode layer, the pixel walls () being made of a hydrophilic material; performing plasma etching on the substrate () having the pixel walls (), the power of the plasma etching being 30-1,000 W/m; and heating the substrate () subjected to the plasma etching, so as to recover the hydrophobicity of the hydrophobic insulating layer (). According to the method, the technical bias that the display support plate () being treated by means of the plasma etching would influence the quality of the hydrophobic insulating layer () is eliminated.

Method for preparing electrowetting display support plate

Disclosed is an electrofluidic support plate and a method for preparing the same, and an electrofluidic device comprising the support plate. The method comprises the following steps of: providing a substrate which has a surface provided with an electrode layer; arranging a first amorphous fluoropolymer layer on the surface of the substrate, and carrying out hydrophilic modification on a surface of the amorphous fluoropolymer layer; arranging pixel walls on the amorphous fluoropolymer layer after hydrophilic modification; arranging a second amorphous fluoropolymer layer which is a hydrophobic layer; the second amorphous fluoropolymer layer covering all surfaces of the pixel walls and a groove area encircled by the pixel walls; filling the groove area encircled by the pixel walls with a protective material; removing the second amorphous fluoropolymer layer not covered by the protective material and on a top of the pixel walls; and removing the protective material.

Electrofluidic support plates and preparation method therefor, and electrofluidic apparatus

An oil puncture controlled starting system for an EFD apparatus and manufacturing method therefor, wherein the EFD display structure comprises a base arranged below a lower electrode, and the base is provided with a step, such that a first liquid has a first thickness outside the step and a second thickness on the step, which is less than the first thickness, such a thickness difference renders the first liquid on the step to be punctured by a second liquid firstly when a lower voltage is applied between a upper electrode and the lower electrode, and the first liquid is pushed by the second liquid to move from a first area to a second area.
