The present invention relates to a TV, and more particularly, to a hologram TV so that different broadcasts can be viewed according to a viewing angle viewed through a single display device using a hologram.

1 illustrates a TV receiver structure according to the related art, and includes a tuner 102 for selecting and amplifying a radio wave of a desired channel, and receiving and converting a frequency to perform stable amplification in consideration of specific selectivity. Regardless of the size of the channel, the intermediate frequency amplification circuit section 103 for amplifying the intermediate frequency signal of a constant frequency at all times, and the detection circuit section for detecting an image signal by removing the carrier from the signal output from the intermediate frequency amplifying circuit section 103. (104), an image amplifying circuit section (105) for amplifying the video signal to the size required to operate the water pipe (109), and a synchronizing signal separated from the video signal and synchronized with the resolution operation of the image performed on the transmission side. And a deflection circuit section 108 for reproducing a correct image by performing the assembly operation of the image. A color reproducing circuit 106 is used to demodulate the color signal by subtracting the transmitted color signal included in the image signal to reproduce the three primary color signals of red, green, and blue. When the light emitters are regularly painted in a dot or line shape and the electron beams are modulated according to the three primary color signals, and each emitter emits light corresponding to the magnitude of the three primary color signals, a color image close to the color of the original subject is reproduced.

In this case, in the case of black and white, as shown in FIG. 2, an electron gun 11 and a fluorescent screen 14 are enclosed in the appearance of a funnel-shaped glass tube, and the glass tube is swollen with a cone portion on the right side; It is separated into a small cylindrical neck part on the left side, and a phosphor that emits light when colliding with an electron is applied to the lower part of the cone part, and the inside is maintained to maintain a high vacuum state, and the electron gun 11 is for emitting electrons. A plurality of cylindrical electrodes are used to collect the cathode and the radiated electrons, electron beam them, accelerate them, and concentrate them on the fluorescent surface 14. The final electrodes of the cylindrical electrodes are coated on the inner surface of the neck portion and the cone portion. The conductive film is connected to the conductive film, and the conductive film is attached to the aluminum film surrounding the phosphor.

At this time, the electron is relatively slow at the time of exiting from the cathode, but when it is output from the electron gun, it is determined and accelerated by the voltage applied to the final electrode (anode button) 13. Accordingly, the electron beam is output from the electron gun and accelerated constantly so as to accelerate Collides with and emits a light.

In addition to accelerating electrons emitted from the cathode, the electron gun also modulates the electron beam, by controlling the amount of electron beam flow that matches the size of the image signal, so that the electron beam becomes the smallest spot on the fluorescent surface. The deflection of the beam for scanning is performed electronically by attaching a deflection coil to the outside of the neck portion of the water pipe.

On the other hand, as shown in Fig. 3, the universal color tube has a fluorescent screen 6 which is finely decomposed into red, green, and blue (R, G, B) three-dot dots, and a new mask. (7) and the electron gun divided into three zones, and the fluorescent screen 6 has three kinds of microscopic phosphor dots having a diameter of about 0.35 mm each emitting red, green, and blue light. The shadow mask is a thin film sheet having a thickness of about 0.15 mm placed about 10 mm in front of the screen, and a hole having a diameter of 0.25 mm is regularly arranged as a pitch of 0.56 mm to 0.65 mm. One configuration corresponds to one to three sets of red, green, and blue phosphor dots as shown in FIG.

The number of holes is 200,000 to 400,000, but the transmittance of the electron beam is blocked by the shadow mask to be about 15% to 18% at the center of the screen, and the three electron guns are mounted on the neck 1 of the receiving tube to form a fourth. In the so-called delta arrangement as shown in the figure, the cross section on the left side is arranged in an equilateral triangle, and emits a modulated electron beam as red, green, and blue color signals.

At this time, the three electron beams emitted from the electron gun are deflected to scan the entire surface of the screen, but each electron beam is blocked by the shadow mask, and only the fluorescent substance dots of the corresponding color only hit the values passing through the holes.

That is, a straight line connecting the deflection center of each electron beam and the center of a hole of the shadow mask as shown in FIG. 6 is made to pass through the center of the corresponding phosphor dot, respectively, and the electron beam is modulated by a color signal. Therefore, according to the color signal, one set of dots emits red, green, and blue colors to reproduce all colors.

In order to reproduce the image using such a water tube, it is not only to control the electron beam of the water tube in the received video signal, but to move the image from the upper side to the lower side while scanning the electron beam in the horizontal direction. It is necessary to make the water screen by performing the assembly scanning in the same shape as the disassembly scanning. The synchronization circuit 21 of FIG. 7 synchronizes the disassembly scanning of the screen on the song-side and the assembly scanning of the screen on the water-side.

In addition, in order to scan the water image, the vertical and horizontal deflection circuits 22 and 23 must be deflected, and the deflection of the water pipe causes a sawtooth current to flow through the deflection coil 24 mounted on the neck portion. In synchronism with the transmitted synchronization signal included in the video signal, 15.75KHz is used for horizontal injection and 60Hz for vertical scanning.

Here, the direction of the deflected electron beam is determined by Fleming's left-hand law as shown in FIG. 8, and the amount of deflection is increased in proportion to the strength of the magnetic field, for example, as shown in FIG. If two sets of coils are placed in the current and the current flows, the electron beam is deflected up, down, left and right by Fleming's left-hand rule, and the size and direction of the electron beam changes according to the magnitude and direction of the current flowing through the coil.

However, such a conventional TV receiver has a problem in that it is impossible to watch different broadcasts at the same time since only one channel can be viewed per unit or only two channels can be watched when using a sub-screen.

Therefore, an object of the present invention is to solve the above problems, by attaching a plurality of electron guns for the electron beam of different signals to the receiving tube and the electron beam is passed through the shadow mask to hit the fluorescent screen screen to emit only the beams of different electron guns when emitting light By providing a hologram TV to view and view only signals from different electron guns at various angles.

In this way, an appropriate current flows through the deflection coil 311 to scan the electron beams emitted from the electron guns 315 and 315 'according to Fleming's left-hand law.

In this case, the electron beams are inputted with different Youngsan signals, and are subjected to a modulation process such that the amount of flow is controlled so as to be accelerated at a desired speed through an anode button and to fit the size of an image signal.

And as shown in the shadow mask 31, as shown in FIG. The fluorescent screen is configured to adjust the deflection coils by doubling the number of holes arranged in the direction of the two holes, and to pass the electron beam of a predetermined electron gun to one of the holes adjacent to each other, and to pass the electron beam of the other electron gun to the neighboring holes. 314 denotes three kinds of micro-cylindrical phosphor dots emitting red, green, and blue, respectively, to form an equilateral triangle, and the surfaces thereof are minutely angled so that each part of the light emits an electron beam of one electron gun. And the other side emits electron beams of different electron guns, and according to the viewing angles (ⓐ, ⓑ), respectively, as shown in FIG. Can be seen.
