Description

The invention relates to the field of entertainment and educational complexes using virtual reality and can be used in the field of entertainment, education and culture, for example, in advertising, presentation, entertainment or educational equipment, as part of exhibition stands, means of informing the public and other similar means.

The display device disclosed in the international application WO 2017125718 A1 published on July 27, 2017 is known from the prior art. The specified device contains a means of projecting an image projecting an image onto an inclined mirror that rotates around its axis. The rotation of the mirror makes it possible to display visual information within 360 ° of the azimuthal plane, which makes it possible for it to be alternately perceived by viewers who are on different sides of the display device. However, this solution does not provide the ability to simultaneously observe the image by all viewers located on opposite sides of the device. In addition, the need to use projection devices with a lens as part of the known device as a whole complicates its design.

Also known from the prior art is a display device selected as the closest analogue of the claimed invention and disclosed in the patent application JP 2000330074 A published on 11/30/2000. The specified device contains two monitors projecting images onto an inclined translucent flat mirror. The ability to adjust the tilt of a translucent mirror allows you to implement and maintain visual effects, which include the ability to create two-dimensional (2D), three-dimensional (3D) and transitional type of images. Moreover, the specified device, selected as a prototype, does not allow visual information to be displayed to all viewers who are on different sides of the display device, and does not allow to implement any other visual effects, except for the aforementioned and characteristic of this prior art.

Disclosure of Invention

The objective of the present invention is to provide a means of displaying information, ensuring the achievement of a technical result, consisting in the ability to simultaneously display visual information, supplemented by the effect of dynamic rotation of the image, to viewers who are on different sides of the display device, while simplifying the design of the device.

This problem is solved, and the technical result is achieved due to the fact that the claimed display device contains at least two monitors, at least two tilting mirrors and is characterized in that at least two monitors are placed in one plane, while each of the mirrors is located in relation to the corresponding monitor so that the image from the monitor is projected onto it, each of the mirrors is made inclined with respect to the plane of the monitors, and each of the monitors n with the possibility of rotation around an axis perpendicular to the plane of the monitors.

In a particular embodiment of the invention, the system also includes motors that drive the monitors into rotation, controls that control the rotation of the engines and the image on the monitor screen. These controls can be performed as part of one or more (for example, the number of monitors) computers (servers) containing the appropriate software and control the operation of the engines and the image on the monitors, providing the possibility of both synchronous operation of the engines and independent when the engines can rotate at different times, at different speeds, perform a different number of revolutions, rotate monitors at different angles, etc. These controls can synchronize the images on the screens of monitors, that is, provide simultaneous output of the same image on the screens of monitors. Also, these controls provide the ability to simultaneously display on each screen of the corresponding monitor an image that is different from the image on the screen of another monitor.

The plane of the axis of rotation of the monitor can pass through its center and the center of the projection of the mirror onto the plane of the monitors.

The image on the monitor screens can be static or dynamic (drawings, photos, videos, animations, etc.).

As a monitor, any monitor can be used, such as OLED, LED, LCD, LCD with any resolution from HD and higher, including full-HD 4k, 8k and similar displays.

The rotation of the monitors can be carried out both 360 ° degrees, and 180 ° and 90 °. In the last two cases, it is advisable to use limiters that prevent the monitors from rotating beyond the specified ranges.

Mirrors can be either fully reflective or partially, for example, translucent, for example, in the form of a transparent reflective screen. Mirrors can be made of glass with a advising reflective coating or of a mirror (partially reflective) film mounted on an appropriate frame. Mirrors can be located on the same axis in opposite directions so that the lines of intersection of the planes of the mirrors with the plane of the monitors are parallel. The angle of inclination of the mirrors to the plane of the monitors may be 45 °.

The number of monitors may correspond to the number of mirrors. Mirrors, in turn, can be selected in an amount sufficient to create a full panoramic image. In this case, their minimum number is 4, but may be large (6, 8, 10, 12, etc.), depending on the needs, while pairs of mirrors can be oriented perpendicular to each other. Monitors can be located on top, bottom or side of mirrors. Any of the monitors and / or their groups can be installed on the tool (guides, carriages, platforms), providing for the movement of the monitor vertically and horizontally.

In the case of using translucent mirrors, a variant is possible where two monitors correspond to each mirror, while the corresponding groups of monitors can be located in parallel planes. At least part of these monitors of one of the groups can be performed without the possibility of rotation (stationary).

The achievement of the technical result, which consists in the possibility of simultaneously displaying visual information, supplemented by the effect of dynamic rotation of the image, to viewers who are on different sides of the display device, while simplifying the design of the device, is due to the following.

The ability to simultaneously display visual information to viewers who are on different sides of the display device when supplemented with the above effects is due to the fact that the claimed solution, in contrast to the closest analogue of JP 2000330074 A, contains at least two display surfaces, as which are inclined mirrors. The specified allows you to watch the image at the same time a large number of viewers who are on different sides of the display means.

As the effects of dynamic image rotation, a new type of effects appears due to the rotation of the monitors around an axis perpendicular to the plane of their location. The combination of the rotation of the monitors with the demonstration of the corresponding image allows you to get a new type of visual effects.

The reliability of the design is due to the lack of a large number of movable elements, as well as complex optical projection devices, and, accordingly, the lack of the need for their precise placement and adjustment.

Additional effects may include effects associated with the superposition of images from two monitors on top of each other.

The generated image, depending on the degree of reflection / transmission of the mirrors, the angle of their inclination, can relate to the field of two-dimensional 2D, three-dimensional 3D (built on the principle of the Pepper's ghost illusion) and transitional type of images.

Brief Description of the Drawings

The invention is illustrated in the drawing, where in FIG. 1 schematically shows an embodiment of the claimed device.

In a private embodiment, the claimed device includes two monitors (1), made with 360 ° rotation and located on top of a pair of mirrors tilted in opposite directions (2), as well as two fixed monitors (3) located below to divide the virtual image into two plans (foreground, background / background).

The system can be assembled into a structure containing a frame for placing monitors and mirrors, and having, in general, a cube or parallelepiped shape. The frame may have a length of 5520 mm, a width of 2980 mm, a height of 2980 mm. The size of the mirrors may be 2400 by 2600 mm, or the mirrors may have a square shape of the appropriate size.
