Patent ID: 8693077

Claim:
A display having an image area, comprising: electronically controllable pixels situated in a raster-like pattern, wherein each pixel has at least one color level including a flat container, the flat container being clear and transparent at least one visible side and having an interior connected to a color reservoir; and an actuating device, wherein a pressure of content of the color reservoir is controllable by electronic control of the actuating device, which acts on a movable wall of the color reservoir, wherein, when the content is placed under pressure, colored liquid reaches the color level from the color reservoir, displaces a clear, transparent liquid or gaseous medium which reaches a gas space or a space behind the movable wall via a channel, and, when pressure is reduced in the color reservoir, the colored liquid is transported back into the color reservoir from the color level and the clear, transparent liquid or gaseous medium reaches the color level, the color reservoir being flat and extending parallel to the color level, and wherein the actuating device includes at least one linear drive, wherein an actuator of the linear drive causes the displacement of the movable wall and moves in a plane parallel to the plane of the color reservoir, wherein a wall of the color reservoir facing away from the color level at least partially forms the movable wall, and wherein the movable wall is supported via a sliding surface on the actuator or a part connected thereto, so that the movement of the actuator is converted into a shortened lifting or lowering movement of the movable wall extending perpendicularly thereto.
