Known patent of Russia №2117413 "Method of reproduction of color television images", which consists in receiving light fluxes of the three monochrome images in the basic red, blue and green colors, the transfer of the received streams to the screen and the formation of a complete image on the screen using optical fibers, the ends of optical lenses that form the screen. To obtain a color image of each point of the color images with the same coordinates of the luminous flux transmitted to the screen with the same coordinates. This method requires the implementation of three fiber optic cables that on the one hand touch screens three monochrome picture tubes, creating a luminous flux, and on the other hand, the three optical fibers coming from different tubes with the same coordinates at the end, which converge into a single optical fiber with an optical lens and form elements of a larger screen with the same coordinates. When this light is passed through all the fibers simultaneously. Melanie three monochrome signals within each picture element is on the surface of the screen, and not in the human eye, as is the case with the known constructions of tubes for color television. Light fluxes of red, blue and green, passing through the fibers are blended in a light diffusing the base of the screen and give the resulting color according to their specific content. The use of three fiber optic cables complicates and increases the cost of construction. In addition, the inconsistency of the angular aperture of the radiating television and fiber optic lead to a significant loss of radiation at the input radiation from a television screen in the fiber. The screen apparatus occupy a significant amount with a small angular aperture of the video. The screen is not designed to work with projectors and other light sources.

Known RF patent №2116703 "method for the production of static and dynamic laser-color images and laser projector for its implementation". In the known technical solution is disclosed a device for controlling laser beams to display on the remote screen color static and dynamic laser image, which consists of a source of laser radiation, in which there are laser beams of red R, green G and blue In color, control device and a light-diffusing screen. The image of a particular color separately focuses on ek is ane own output optical system. Color image formed by R, G, B-channels are combined on the screen mechanically, by aligning the output of the lenses and, more precisely, with the help of special computer programs combining images from different channels. Full-color focused image exists only in the plane of the light-diffusing screen, a remote at a fixed distance. This technical solution has the following drawbacks:

1. The image on the screen plane consists of a set of R, G, b pixels, the apparent brightness of which to a casual observer, depends on the solid angle of observation, the absorption coefficient of the surface of the screen for wavelengths of radiation used lasers, and the values of the distribution of the reflection surface of the screen in the direction of observation. Typically, the screens have a diffuse reflecting surface with quasielementals the reflection indicatrix. With limited power lasers operating in the continuous generation mode, (the total radiation power in R, G, B-lines does not exceed 15-20 watts), the observation of a relatively bright picture on the big screen with such reflection indicatrix is possible only in conditions of almost total darkness, which significantly limits the use of such devices for the purposes of advertising and information transfer.

2. Device is istwo does not allow you to work with a spherical screens and has a limited aperture of the video.

3. To achieve high brightness on the big screens require high-power lasers with high power consumption, posing danger to the eyes of the spectators.

4. Not suitable for use in the home, where a small amount of space, low energy consumption.

The screen consists of a hollow closed figure 6, the walls of which are translucent or transparent and have light-scattering (e.g., matte) on top of the spine. Inside screen is placed sources videoinformation, generators, light diffusing particles and other technical tools involved in creating the video. A computer over a communication line 37 controls the operation of the driver in block laser projectors 38, and line 50 controls the operation of the driver in block laser projectors 60 with modulators of the spatial position of the laser beam 61, 62, 63, 64. Similarly on lines 47 and 53, 48 and 52, 49 and 51, the computer 36 controls the operation of the driver of the generators of the light-diffusing particles 56, 70, of sound sources 54, 69, projectors and sources of light signals 57, 71, respectively.

The device (10 Formula) proposed to use fiber cables 39, 40, 41, 42 for connection of the output unit with the laser emitters 38 to the input of the projection optics 43, 44, 45, 46. In this case, the laser emitters is installed outside of the screen and can be moved outside the infotainment space. The radiation from each laser unit 38 with matching optics placed in the block 38, is introduced into the fiber cables 39, 40, 41, 42. On fiber cables laser radiation is supplied to the inside of the screen and goes to the inputs 1, 2, 3, the N-th projectors. The projector 43, 44, 45, 46 focuses the laser radiation through the first, second, third, nth modulators of the spatial position of the laser beam 61, 62, 63, 64 on the surface of the screen. Modulators receive the control signal from the computer 36 via communication lines 50 and direct the focused laser beams to the screen specified by the program, creating on-screen video.

If the laser light source 38 includes three multi-colored laser source 10, 11, 12 wavelengths respectively λ1that λ2that λ3three modulator brightness of the beam 13, 14, 15, a mixer 16, a radiation with a wavelength of λ 1to the input of the modulator brightness of the beam 13. Line 34 is fed to the modulator control signal from the output driver 31. To the input of the driver 31 is a control signal from the computer 36. Under the action of the output driver 31, the modulator 34 changes the power beam with a wavelength of λ1. Similarly, under the action of the output drivers 32 and 33 modulators 35 and 36 change power beams with wavelengths λ2and λ3. The three beam is fed to the input of mixer 16, where with the help of deaf mirrors 17, 20 and mirrors with selective transmission 18, 19 at the output of the mixer together in one bundle. With the mixer output laser light with brightness and color specified by the computer, is supplied to the element 21 and is inserted through the input element 22 in the optical fiber 23.

In this line SAUD, the driver, the computer signals on the control inputs of SAD. Changing the frequency of the control signal, change the position of the beam on the surface of the screen. Changing the amplitude of the control signal, change the power of the laser beam on the surface of the screen. Changing independently or pump current of each beam, or modulator directly independently change the intensity of the beam at the output of each of the three lasers, as described above, change the color of the beam.

The device 17 Formula contains t and is independent of the laser source 86, 87 and 88 with narrow-band acousto-optic deflectors (WOD). In this case, each channel is open to the adder as follows.
