Description

display system

The invention relates to a display system and a method for displaying at least one display content.

A display or a display panel for displaying a display content may be elastically deformable and bent in at least one direction, wherein it is, for example, possible to wrap the display in a cylindrical manner. Furthermore, it is conceivable that a display has a shape with an arbitrary outer contour. In this regard, it is also possible that such a display does not require an edge. An embodiment of an edge of a display can be influenced, for example, by arranging a driver of the display between individual pixels of the display. Furthermore, it is possible that small segments of a display, which have no edge or frame, can be positioned very close to each other. Such displays are, for example, bendable and / or windable like a sheet of paper. However, due to such possible deformation, apart from jarring the entire display, no concrete haptic feedback can be generated for a user.

A device described in EP 2 173 082 A1 comprises a plurality of panels which can be positioned relative to each other, each panel having a display panel. Thus, it follows that this device can, for example, be folded in three dimensions.

A portable electronic device that is from the publication

EP 2 993 870 A1 discloses a bendable display. An interface system for a user is in the document

WO 2009/088985 A1. This interface system includes a plurality of elastically deformable switches. Against this background, it was a task, a form of a

Flexible setting of the display system.

The display system according to the invention has a plurality of display segments, a flat flexible and / or elastic display carrier and an actuating device. In this case, at least one display segment has an upper side with a first display field for representing at least one first display content. The display carrier has a front side and a rear side. The display segments are arranged side by side on the front side of the display carrier, wherein the upper side of the at least one display segment faces away from the front side of the display carrier, whereas a lower side of the at least one

Display segment is arranged on the front side of the display carrier. The actuating device has at least one actuating element, which faces the rear side of the flat elastic display carrier. The at least one actuating element is designed to act on the planar elastic display carrier at its rear side and to deform and thereby a position of at least two

In an embodiment, the top and bottom of the at least one display segment are congruent. The at least one display segment has at least one angular one

The upper side and possibly also an angular underside, wherein the upper side and possibly the underside of the at least one display segment usually regularly square, for example. Diamond-shaped, rectangular or square, or usually regularly hexagonal, for example. Hexagonal, is formed.

Furthermore, the at least one display segment has a

three-dimensional body, which is bounded by the top and the bottom, wherein the top and the bottom of the at least one display segment in configuration have the same shape and are arranged parallel to each other, wherein the top and bottom are connected to each other via at least one outer side. Thus, it is possible that the body of the at least one display segment is formed as a polyhedron with a four- or hexagonal base surface having the shape of the top and bottom, respectively.

Thus, it is also possible that the at least one outer side of the at least one display segment has at least one second display field for displaying at least one second display content. With the at least one second display field, which is perpendicular to the first

Display panel is formed on the top, the at least one second display content is to be emitted perpendicular to the first display panel.

Display segments at least one outer edge, wherein outer edges of Display segments, which are arranged on the display medium immediately adjacent to each other, facing each other.

It is also possible that two immediately adjacent

Display segments are connected to each other via a flexible hinge.

In addition, the underside of the at least one display segment and the front side of the display support are connected to each other via at least one connecting element, wherein the at least one display segment is movably connected and / or movably attached to the display support relative to the display support via the at least one connecting element.

In a possible embodiment, the display medium comprises at least one layer, for example two layers, wherein a first layer consists of flexible, elastically deformable material. A second layer serves to stabilize the first layer and thus of the display support, wherein the second layer is also elastically deformable and consists of spring steel or plastic or a combination of spring steel and plastic. The first layer is more flexible than the second layer. In this case, it is possible for the first flexible layer to be assigned to the front side or bounded by the front side. The second stabilizing layer is assigned to the back or limited by the back.

The at least one actuating element has in design a body with a cam-shaped outer surface and is rotatable about a rotation axis, the outer surface in at least one point, for example. Along a line, rests against the back of the display support, wherein upon rotation of the body, a distance between the axis of rotation and the

Display carrier is variable. Thus, the elastically formed

Display carrier deformed with the at least one actuating element and changed a spatial arrangement of at least two display elements relative to each other.

The method according to the invention is intended for operating a display system which has a plurality of display segments, a flat elastic display carrier and an actuating device. At least one display segment has an upper side with a first display field for displaying at least a first display content. The display carrier has a front side and a rear side. The display segments are arranged side by side on the front side of the display carrier, wherein the upper side of the at least one display segment faces away from the front side of the display carrier, wherein a bottom of the at least one display segment is arranged on the front side of the display carrier and usually connected thereto. The actuating device has at least one actuating element, which faces the rear side of the flat elastic display carrier. With the at least one actuating element, the two-dimensional elastic display carrier is acted upon and deformed on its rear side, a position of at least two display segments being changed or varied relative to one another.

Actuator displaced relative to at least one other display segment and thus changed in position. This means in an embodiment that the at least one display panel, for example, vertically out of the plane that is set in the basic operating position, is moved out. Thus, in a conceivable operating position, it is possible for a plurality of display segments to be displaced relative to one another along an axis oriented perpendicular to their upper sides and correspondingly arranged thereon. Alternatively or additionally, it is possible in at least one further operating position that upper sides or display fields arranged thereon of two display segments are arranged relative to one another at an angle which is greater than zero degrees and less than 180 degrees.

Thus it is u. a. possible, with the display segments of the display system a

display continuous contiguous display content consisting of individual display contents of the individual display segments

is composed, which is also possible in a respective operating position, if the display system adopts a respectively adapted form or geometry.

The display segments with, for example, hexagonal upper side, due to being acted upon by the at least one actuating element of the actuating device, assume different operating positions of the actuating device
