Abstract

Apparatus for displaying images comprising at least one polyhedron (10), on the surfaces (12) of which a plurality of light sources (14) is arranged, which can be controlled individually or successively by means of a computer program, whereby on the surfaces (12) of the polyhedron Still images or moving images, movies, videos or video sequences can be displayed, so that the surfaces (12) of the polyhedron (10) are formed as screens.

Description

The invention relates to a device for displaying still or moving images such as films or videos.

State of the art

For the presentation of films or videos, for example at major events, screens or large screens are suitable.

For example, an "active image point module for large events" is known ( DE 10 2007 009 636 A1 ), in which a plurality of picture-dot modules in their entirety form a display surface for pictures or movie or video sequences, and wherein these picture-dot modules form independent units, the module comprising a element for emitting colored light, the a controllably controllable with respect to the emitted color and / or brightness light source is.

Also known are video display screens made of LED elements. In such video display screens, there are several problems, particularly regarding the overall brightness of the screen, which is limited by the brightness of the blue LED elements, since the blue LED elements are usually darker than the red and green LEDs. Other disadvantages of the large LED screens result from the heat, the poor matching of the color due to variations in the production and the limited life of the individual pixels.

Some of these problems have been minimized, for example, by an integrated red, green and blue LED package that can produce any color and therefore serve as a single pixel of a large screen.

A disadvantage of the presentation of films or videos on flat, large screens, however, is that there must be large wall surfaces for installation of the screen and that the films can only be seen from one side of the screen. Large parts of rooms therefore remain unused.

The object of the invention is therefore to provide a display option for moving images available, which allows a greater latitude in the installation in rooms or outdoor areas and increases the visibility of the presented images.

Disclosure of the invention

An apparatus for displaying or displaying still or moving images, such as films or videos, comprising a three-dimensional body is proposed. This body is a polyhedron, so a Vielflächner. The polyhedron is formed from polygonal, ie "polygonal" surfaces, which together form the three-dimensional polyhedron. The polyhedron is bounded by straight surfaces and is for example a cube or an octahedron of a three-dimensional coordinate system.

As suitable forms such as cubes, Qader, prisms, pyramids and spade come into question. The polyhedra may be regularly formed, so platonic body of congruent polygons, such as the dodecahedron, or as Archimedean, Johnson or Catalan body.

All surfaces of the polyhedra have a plurality of LED elements. The surfaces thus have the function of LED display surfaces. White or colored, to white miscible light-emitting diodes (LEDs) are used. The high number of pixels, which is generated by the dense arrangement of the LEDs, allows a high image quality. The pixel resolution is selectable depending on the distance to the viewer depending on the room size.

In this case, the processes for displaying images, video sequences or films are controlled by means of a computer, either a central computer or a computer responsible for each individual device or parts thereof. Each LED display area of the polyhedron can be controlled separately and thus a variety of films or videos can be played and displayed simultaneously. The LED display surface has in particular a plurality of LED modules. The LEDs are mounted on the LED module. Like every LED display surface, each LED module can also be controlled individually, independently of each other or together. The LED modules can be connected to form a so-called cabinet and then form the LED display area.

The polyhedra can be mounted in different ways in the room or on open-air grounds. They can be fixed, standing or hanging. For a movable mounting is a foot or a bracket with a bearing, such as a ball bearing used. Thus, the body in the room standing or hanging freely and optionally be arranged rotating. The suspension can be z. B. on a chain or rod with a thread. A gear can for increased stability in sliding or ball bearings be used. It is conceivable to increase the safety of the use of, for example, one or more, especially three chains. A bottle or cable may also be used, so that the polyhedron, which is for example suspended on the ceiling of a room or on a rack, can be drained for repair, cleaning or maintenance purposes.

The device according to the invention has the advantage that images, films or video sequences, for example, for advertising purposes, can be presented in the smallest space and are visible from all directions from the viewer and the representation on a canvas screen not only from one side consider.

Furthermore, a greater attention of the audience is achieved by the rotating arrangement of the polyhedron.

Another advantage is that the various LED display surfaces of the polyhedron can display very different images or films at the same time, resulting in completely different image impressions from every perspective.

Further advantages and advantageous embodiments of the invention are the following description of the figures, the drawings and the claims removed.

An embodiment of the solution according to the invention is explained in more detail below with reference to the attached schematic drawing. It shows:

The viewing angle in this embodiment is horizontal 140 °, vertical 120 °. The optimum viewing distance is 2.5 to 120 m. The device weighs approx. 280 kg in this version.

The LED cube 10 in this embodiment is stored upright and can about its axis 16 be rotated, here represented by an arrow. There is also a ball bearing 18 for use. The LED cube 10 will be on one of its corners 20 on the ball bearing 18 placed. The construction has a pedestal 22 on.

The LED cube 10 However, it can also be fixed or hanging on fasteners such as rods, ropes, chains, cables or the like. arranged or arranged to rotate. It can joints, gears or the like. be used.

The LEDs 14 are red with an intensity of 450 to 600 mcd, green with an intensity of 1350 to 1500 mcd or blue with an intensity of 500 to 650 mcd or white. The LEDs 14 are on LED modules 26 arranged, which can be joined together to form a so-called cabinet. The LED modules have an SMD 35/28 chip. The colors of the LEDs are selected by this one chip. Every LED 14 is controlled by a computer. This is indicated by the LED cube 10 at least one power supply unit, further receiver means for the remote control signals of the computer, at least one microprocessor and at least one memory unit.
