The disclosure relates to a pixel array for an electrofluidic display element, comprising a plurality of adjacent pixels that form the pixel array, each pixel having a pixel chamber with a polygonal, preferably rectangular, pixel surface and a height. Each pixel has at least one main reservoir channel which opens, via a first width (D) and length (L), into the pixel chamber and a single- or multi-part reservoir channel which surrounds the chamber, borders the pixel surface and opens, along its length and a second width into the pixel chamber. A polar and/or electrically conductive liquid is or can be held in the pixels, said liquid being capable of motion back-and-forth between the reservoir channels and the pixel chamber by the application of an electric field, and the reservoir channels surrounding adjacent pixels run towards each other in a corner region in which the adjacent pixels border one another. The invention is characterised in that the second width (A) is smaller than the first width (D), the at least one main reservoir channel of each of the adjacent pixels opens into the surrounding reservoir channel at the corner region via at least one mouth junction having a third width (C) which is smaller than the first width (D), and the height of the pixel chamber is greater than or equal to the second width (A). Also disclosed is a corresponding display element.
A pixel array for an electrofluidic display element comprising a plurality of adjacent pixels, pixels forming the pixel array each having a pixel chamber with a polygonal, preferably rectangular, pixel surface and a height, wherein each pixel has at least one main reservoir channel that opens into the pixel chamber over its first width (D) and length (L), and a single- or multi-part surrounding reservoir channel that borders the pixel surface and opens into the pixel chamber along its length and its second width (A), wherein a polar and/or electrically conductive fluid is, or can be, held in the pixels, said liquid being movable back and forth between the channels by applying an electrical field, wherein the surrounding reservoir channels of adjacent pixels run towards one another in a corner region, wherein the second width (A) is smaller than the first width (D), wherein the at least one main reservoir channel of each of the adjacent pixels in the corner region opens into the surrounding reservoir channel via at least one junction which has a third width (C) that is smaller than the first width (D), and wherein the pixel chamber height is greater than, or equal to, the second width (A).
The pixel array for an electro-fluidic display element, having a plurality of adjacent pixels that form the pixel array each pixel having a pixel chamber which has a polygonal, for example rectangular, pixel surface and a height, wherein the pixels are arranged in a regular pattern of lines and columns, each pixel having a surrounding reservoir channel that borders the pixel surface and opens into the pixel chamber along its length and its width, wherein a polar and/or electrically conductive fluid is, or can be, 0 held in the pixels and can be moved back and forth between the reservoir channel (5) and the pixel chamber by applying an electrical field, where the surrounding reservoir channels of adjacent pixels are fluidically connected in corner regions where four adjacent pixels border one another and form a common reservoir channel grid and the width (A) of the reservoir channels is greater than, or equal to, the height of the pixel chamber.
