摘要： 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.

摘要： A water-repellent coating lens for a camera has enhanced abrasion resistance performance and chemical resistance performance of the water-repellent coating. The water-repellent coating lens includes a lens base layer and a plurality of coating layers deposited on the lens base layer. The plurality of coating layers include a first water-repellent coating layer containing a fluorine-based compound and a second water-repellent coating layer positioned on the bottom surface of the first water-repellent coating layer and containing an inorganic oxide.
