Manufacturing method of electrowetting display assembly

Abstract

The invention provides a manufacturing method of an electrowetting display assembly. The manufacturing method comprises the steps of: providing a lower substrate and cooling the lower substrate to a predetermined temperature, wherein the lower substrate is pre-formed with a lower electrode, a hydrophobic dielectric layer and a patterned pixel wall; filling a hydrophobic substance in the pixel wall, wherein a solidifying point of the hydrophobic substance is higher than a predetermined temperature, so that the hydrophobic substance is in a solid state; placing a predetermined amount of hydrophilic substance on the hydrophobic substance, wherein a solidifying point of the hydrophilic substance is lower than or equal to the predetermined temperature, so that the hydrophilic substance is in aliquid state; providing an upper substrate, wherein the upper substrate is formed with an upper electrode and an adhesive for sealing; and assembling the upper substrate and the lower substrate by means of a jig.

Description

technical field [0001] The invention relates to the field of electrowetting display, in particular to a manufacturing method of an electrowetting display component. Background technique [0002] Electro-wetting refers to changing the wettability of a droplet on a substrate by changing the voltage between the droplet and an insulating substrate. Electrowetting display components generally include a hydrophilic layer and a hydrophobic layer, wherein the hydrophilic layer and the hydrophobic layer are immiscible. Current electrowetting display components generally need to be assembled underwater, because when assembled in air, the hydrophobic liquid used as a hydrophobic layer will be distributed on the air-water interface. In order to avoid miscibility between hydrophobic and hydrophilic substances, it is usually necessary to bring the ink into contact with the underlying substrate surface in the absence of air, so the assembly of electrowetting display components usually nee...

Problems solved by technology

However, this fabrication method requires a large amount of hydrophilic substances, and considering the cost of other electrolytes, it is almost impossible for electrowetting display components assembled by this fabrication method to use substances other than water as electrolytes.
