Description

Holographic optical illusion has been known for a long time, since the 60s of the XX century, and by now it is a three-dimensional (3D) image of an object or symbol hovering in the air without any visible restrictions. Such a spectacle makes a very strong, mesmerizing impression on the audience, attracts thousands of eyes and certainly serves the benefit of the brand on display using the visual effect of Pepper's Ghost.

In the last third of the 20th century, humanity experienced a brief boom in holographic art. Exhibitions, galleries with samples of works were opened, but none have survived to this day, Wikipedia notes with regret. And no wonder - such a miracle of digital technologies becomes available only today, when such technologies are included in everyday use.

Closest to the claimed technical solution is a four-sided holographic pyramid (patent RU 144 372 U1, published: 08/20/2014), which contains a housing containing side inserts; four glasses installed in the body of the pyramid; a video signal display device, which is an LED panel or TFT matrix, hidden hidden in the pyramid body; LED, creating volume for video content, located in the LED housing; video source; a device for playing sound; pyramid on / off block.

A similar design is taken as the basis of our production and is presented by us as the closest analogue of a real model. However, in addition to all the listed advantages, the 4-sided holographic pyramid described by us also has very serious disadvantages, of which the main one is the strong heating of the pyramid itself and the video signal display device. This alone is enough to completely ruin any impression of the effect, and if we add in the lack of clarity of the picture due to the exploitation of LED-panels or TFT-matrices.

Besides:

- at the base of the pyramid there was no video signal display device, thereby not allowing the game space to be supplemented with a video signal;

- there was no provision for the use of magnetic hard disks (HDD) and solid state drive (SSD) as a digital storage device;

- sufficient image contrast was not provided, insufficient color depth was displayed (the displayed color gamut was too small), the response time was too long, the display was too thick and heavy (and, therefore, the pyramid design looks bulky), the power consumption was too high;

- the pyramid had a small play area, i.e. it is impossible to display video signal on the base of the pyramid or under the pyramid.

However, in our declared solution, the indicated shortcomings were resolutely and irrevocably eliminated due to the fact that:

- modifications of the body were made from a pyramid to an octahedron;

- the number of video signal display devices has been increased;

- liquid crystal panels with light-emitting diode (LED) backlighting (with matrices IPS [SFT], VA / MVA / PVA, PLS) were used as video signal display devices, a quantum dot display (QLED), displays on organic light-emitting diodes (OLED- displays) or AMOLED displays. Thus, we have achieved a significant reduction in the heating of the device and an improvement in the quality of the video display device.

The technical result is achieved in that the eight-sided holographic octahedron includes a body containing side inserts; eight glasses installed in the octahedron body; three video signal display devices hidden in the octahedron body; two LEDs that create volume for the video image, located in the LED housing; source of video content; a device for playing sound; block on / off octahedron. Moreover, two video signal display devices are liquid crystal displays (with IPS [SFT], VA / MVA / PVA, PLS matrices), a quantum dot display (QLED) or organic light-emitting diode displays (OLED displays), and the third video signal display device is is a transparent liquid crystal matrix (display) or a transparent matrix (display) on organic light-emitting diodes.

The body of the device can be made of painted MDF panels, or aluminum sheets, or painted metal panels, or solid wood, or plexiglass. Side inserts may well be made of glass or polycarbonate. The glass used in the device can be ordinary, tinted or sputtered. Also, glasses can be used with any materials or films additionally applied to them, which give the glass additional properties.

Any media player, computer or any other device capable of playing video files can be used as a video signal source.

As a source for sound reproduction, speakers of reduced size, or any other standard speakers or speakers can be used.

The essence of the utility model is illustrated by drawings, which show:

figure 1 is a frontal view of the octahedron;

Figure 2 is a side view of an octahedron.

The holographic octahedron includes a body 2 made of painted MDF or aluminum or painted aluminum. Side inserts are made of glass or polycarbonate, or any similar materials (optional). Eight glasses 4 and 6, which can be conventional tinted or sprayed. Glass can also be used with any additionally applied materials or films that give the glass additional properties. LCDs (IPS [SFT], VA / MVA / PVA, PLS), quantum dot display (QLED) or organic light emitting diode (OLED) displays are used as the lower and upper video signal display devices 3 and 7. A third video signal display device 5, a transparent liquid crystal matrix (display) or a transparent matrix (display) on organic light-emitting diodes, is installed in the central part of the body.

When the octahedron starts up, LED 1 is automatically turned on. The latter is housed in its own case; in this case, the LED body is located in the upper and lower parts of the octahedron body. A computer or any other device capable of playing video files can be used as a source of video signal and visually displayed information. Loudspeakers of a reduced size, or any other standard loudspeakers, can be used as a device for converting electrical signals into acoustic (sound) and emitting them into the surrounding space (air). The octahedron on / off unit starts / stops the electrical components of the octahedron and is connected to a voltage source using a power cable. A USB Flash card, SD memory card, MMC memory card, hard magnetic disk (HDD), solid state drive (SSD) or any other memory card with a compatible interface is used as a machine-readable source of information.

The holographic octahedron we are describing can be of almost any size, limited only by technological capabilities. Also, this octahedron can be located both vertically and horizontally. In the case of using the octahedron model, it can be positioned, for example, on a store shelf or on an exhibition stand, etc.

The octahedron works as follows: the viewer sees the space inside the octahedron, where glass surfaces are installed at an angle of 45 ° from all sides to the viewer, and does not see hidden display devices. When both display devices (top and bottom) render content, it is reflected in the glass, creating the effect of a ghost image in the visible space of an octahedron. The third display device (transparent matrix) is designed in such a way that the view through its body is preserved from the inside, but at the same time from the outside, when viewing, the integrity of the displayed video image is created. In the octahedron, the transparent matrix serves as a supplement to the playing space zone due to the ability to reproduce a video signal in it and to display information visually, which makes it possible to combine the reproduced content on all installed display devices.

An example of visually displayed information can be offered from water sports. Imagine that on all three display devices hidden in the octahedron, it is shown how an athlete performs a jump from a tower and how during a jump she performs a number of acrobatic actions (at the same time, revolutions, screws, rotations, etc. are shown on the 1st upper display. ); the 2nd central display shows the water surface of the swimming pool and when the athlete approaches it, a smooth transition (splashes, waves, etc.) to the next multimedia zone of the playing space occurs. The last 3rd display can show the underwater environment of the swimming pool that the athlete has entered. Thus, the shape modified into an octahedron provides rich possibilities for displaying various content.

To give various effects on the edge of the octahedron, a tinted film is applied, outwardly invisible if you do not look closely. One of the advantages of using this film is that it gives a specular effect, which makes the edges of the octahedron more "glossy", maximizing reflection. Thus, the image becomes more realistic (it is better seen) and more contrast (due to the formation of a dark background due to the film). Also, the film allows you to make the image three-dimensional. This makes the visuals more vivid and engaging. The scattering of light by the film creates the appearance of an object inside the octahedron.

It is also possible that inside the octahedron, i.e. inside the glasses, an object is installed, for contrast, illuminated by an LED. In the accompanying video, a so-called "mask" is made for this object, namely, the outline of the object is cut out, then in the octahedron itself the object is substituted into this outline. Thus, the object and the video will be in the same plane, and the effect of a holographic illusion is created for the visitor.

Octahedron content is a video that can be made in any computer video production program, and which is broadcast on the glass of the octahedron and on the transparent matrix in the center. Thus, in order for each of the eight glasses to have an image, it is necessary to show all four rollers on the upper display and show all four rollers on the lower display, arranged so that each one is placed on its own glass when reflected.

The clip is played as follows. A USB Flash-card or SD or MMC memory card or hard magnetic disk (HDD) or solid state drive (SSD) is connected to the reader, the reader is connected to a video signal source (for example, a media player or a computer), or the video source has its own reader. The command to auto-load the video is set and when the pyramid / octahedron is turned on, the computer sends a signal (video) to the display. The display, in turn, reflects the video signal onto the glass, and the visitor sees a pseudo-holographic image. The picture may be accompanied by sound from the speakers. There may be an object inside the glass, illuminated by an LED.

In the case of a larger octahedron, a separate LCD (with IPS [SFT], VA / MVA / PVA, PLS matrices), quantum dot display (QLED) or organic light-emitting diode (OLED) displays are installed on each side (on each glass) (OLED displays); these displays display the same video image from one computer, similar to connecting four duplicate displays to one computer.

According to their characteristics, liquid crystal displays LCD (with matrices IPS [SFT], VA / MVA / PVA, PLS), display on quantum dots (QLED) or displays on organic light-emitting diodes (OLED-displays) - in comparison we have indicated the LED-panel and TFT -matrix - provide a reduction in the dimensions of the entire structure and much less heating of the video signal display device itself in a closed space (since they are located in the body of the pyramid / octahedron), and, accordingly, in the pyramid / octahedron itself, in which it is located.

Thus, the implementation of the video signal display device in the claimed device in the form of a liquid crystal display LCD (with matrices IPS [SFT], VA / MVA / PVA, PLS), a display on quantum dots (QLED) or displays on organic light-emitting diodes (OLED-displays) provides achievement of the declared technical result.
