| 摘要 |
The invention relates to a pixel array (1) for an electrofluidic display element, comprising a plurality of adjacent pixels (2) that form the pixel array (1), each pixel having a pixel chamber (3) with a polygonal, preferably rectangular, pixel surface and a height. Each pixel (2) has at least one main reservoir channel (4) which opens, via a first width (D) and length (L), into the pixel chamber (3) and a single- or multi-part reservoir channel (5) which surrounds the chamber, borders the pixel surface and opens, along its length and a second width (A) into the pixel chamber (3). 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 (4, 5) and the pixel chamber (3) by the application of an electric field, and the reservoir channels (5) surrounding adjacent pixels (2) run towards each other in a corner region (6) in which the adjacent pixels (2) 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 (4) of each of the adjacent pixels (2) opens into the surrounding reservoir channel (5) at the corner region (6) via at least one mouth junction (7) 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. |
