Abstract
A display device based on e.g. oil layer break up or oil layer displacement having at least two different states, having a wall () height which is insignificant compared to the pixel width and also to the typical curvature of the oil interface at the tip of the dosing needle (), the pixels are dosed without inserting the needle into the pixels. As the dosing needle no longer has to enter the pixel, pixels can be dosed with oil () from a relatively large injection needle.
