Multi-coloured display device

摘要

The device has a display element (1) with a closed volume divided into a visible partial volume (4) and another partial volume (5). Dimensions of the visible partial volume is selected such that an electrically conductive or polar portion of liquid is pushed from the visible partial volume to the latter partial volume based on young-Laplace pressure in a voltage-free condition of an electrode arrangement. The latter partial volume passes through the visible partial volume and is attached to the visible partial volume that is arranged in a viewing direction of the display element.
