US 2015/0316760 A1 · ELECTRICALLY CONTROLLABLE DISPLAY ELEMENT FOR AN OPTICAL DISPLAY DEVICE, AND CORRESPONDING PRODUCTION METHOD

Abstract

The invention concerns an electrically controllable display element (1) for an optical display device, with a structured layer (2) that has a plurality pixels (3), and with at least one electrode layer (6) directly or indirectly over a structured side (2.1) of the structured layer (2), as well as with an active matrix (7) having thin film transistors, which has selectively controllable electrodes, such that individual or multiple particular pixels (3) can be charged with an electric field, characterized by the fact that the at least one electrode layer (6) extends in one piece over the structured side (2.1) of the structured layer (2), and that the active matrix (7) in the viewing direction is arranged on the display element (1) above the electrode layer (6).

An electrically controllable display element (1) for an optical display device, with a structured layer (2), that has of a plurality of pixels (3), with a pixel volume (3) that stands in fluid communication with at least one reservoir (4) and with at least one electrode layer (6) directly or indirectly on a structured side (2.1) of the structured layer (2), as well as an active matrix (7) consisting of thin film transistors, which has selectively controllable control electrodes, in order to selectively apply an electric field to one or more specific pixels (3), so that between the pixel volume (3) and the associated reservoir (4) an electrical conducting and/or polar fluid (5) is movable back and forth, characterized in that the at least one electrode layer (6) extends in one piece over the structured side (2.1) of the structured layer (2), and that the structured side (2.1) is arranged to face the active matrix (7).

Manufacturing procedure for an electrically controllable display element (1) for an optical display apparatus, that has the following steps:

a) preparing a structured layer (2) that has a plurality of pixels (3) with one pixel volume (3) that is in fluid communication with at least one reservoir (4);
b) placing at least one electrically conductive transparent electrode layer (6) directly or indirectly over a structured side of the structured layer (2);
and
c) arranging an active matrix (7) having thin film transistors, that has selectively controllable control electrodes, at a certain distance from the electrode layer (6), so that an electrical conducting, polar fluid (5) is movable back and forth between the pixel volume (3) and the associated reservoir (4),
characterized in that, in step b) at least one electrode layer (6) is attached over the structured side of the structured layer (2), and that in step c) the structured side (2.1) faces the active matrix (7).
