PATTERN ELECTRODE STRUCTURE FOR ELECTRO-WETTING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17747720 titled 'PATTERN ELECTRODE STRUCTURE FOR ELECTRO-WETTING APPARATUS

Simplified Explanation

The abstract describes a pattern electrode structure for an electro-wetting apparatus that enhances self-cleaning performance for small droplets. The structure includes branch electrodes spaced at regular intervals and sub-branch electrodes extending from the branch electrodes in an inclined direction.

• The pattern electrode structure is stacked between a base material and a dielectric layer of an electro-wetting apparatus.
• It consists of multiple branch electrodes that are spaced apart at regular intervals.
• The structure also includes sub-branch electrodes that extend from the branch electrodes in an inclined direction.
• The sub-branch electrodes have a predetermined length.
• The design allows for more efficient self-cleaning performance, even for small droplets.

Potential Applications

This technology could have various applications, including:

• Microfluidic devices
• Lab-on-a-chip systems
• Digital microfluidics
• Optoelectronic devices
• Display technologies

Problems Solved

The pattern electrode structure addresses the following problems:

• Inefficient self-cleaning performance for small droplets in electro-wetting apparatus.
• Difficulty in removing small droplets from the surface of the apparatus.
• Limited effectiveness of existing cleaning methods.

Benefits

The benefits of the pattern electrode structure are:

• Enhanced self-cleaning performance for small droplets.
• Improved efficiency in removing droplets from the apparatus.
• Potential for better overall performance and longevity of electro-wetting devices.

Original Abstract Submitted

A pattern electrode structure, which is stacked between a base material and a dielectric layer of an electro-wetting apparatus, includes a plurality of branch electrodes formed in a direction perpendicular to an arbitrary plane perpendicular to a plane formed by the pattern electrode structure to be spaced from each other at regular intervals, and a plurality of sub-branch electrodes formed to extend from the plurality of branch electrodes by as much as a predetermined length in an inclined direction, whereby, self-cleaning performance may be more efficiently exhibited even for small droplets.
