Display device

摘要

A display device comprising picture elements, which are constituted by electrowetting elements having at least one first fluid and a second fluid immiscible with each other within a space between a first support plate and a second support plate, the second fluid being electro-conductive or polar. The first fluid in each element is at the side of the first support plate confined by element walls, and the second fluid is shared by a plurality of picture elements, characterized by a preventer for preventing first fluid portions from being expelled from its confinement when forces other than electrowetting forces are exerted on this fluid.

1. A display device comprising electrowetting elements each having at least one first fluid and a second fluid immiscible with the first fluid within a space between a first support plate and a second support plate, the second fluid being one of:
electro-conductive or polar, whereby the first fluid of each of the electrowetting elements is at an inner side of the first support plate and is confined by element walls, and the second fluid is shared by a plurality of the electrowetting elements, wherein the second support plate comprises an array of protruding elements for preventing first fluid portions from being expelled from confinement by the element walls upon forces other than electrowetting forces being exerted on the first fluid, wherein the array of protruding elements protrudes from an inner side of the second support plate.
