    MODULAR TYPE GUIDED BEAM FLAT DISPLAY DEVICE An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that the beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen. The beams in each channel are scanned transversely across its portion of the screen in a transverse direction opposite to that of the beams in the adjacent channels.

    The closest to the proposed is an electronic indicator device containing an evacuated flask with a phosphor screen on the inner surface of the front wall-20 Ki, between the back and front walls of which there are partitions in the form of flat dielectric plates adjacent at least to the back wall separating the space between the backs on a number of longitudinal channels, the first group of electrodes, made in the form of plates, placed y. the back wall along the entire length of the said channels, the second group of plate electrodes placed between the electrodes of the first group and the front wall and made with holes located along the entire length of the channels,. control electrodes for deflecting electrons moving between the electrodes of the first and second groups into the holes, cathode blocks for injecting electrons into the longitudinal channel Between the electrodes of the first and second groups located on one side of all the channels, and pairs of control electrodes for lateral deflection of electrons in the space between the second group of plate electrodes and the front wall, one of which is on one surface, and the second on the second surface of the partitions bounding the channels 2. One of the A significant disadvantage of the known indicator is the significant energy consumption of the control electrodes. The goal of this is to reduce the power consumed by the control electrodes. This goal is achieved by the fact that in an electronic indicator device containing an evacuated flask with a phosphor screen on the inner surface of the front wall, "between the front and rear walls, which houses flat partitions in the form of flat dielectric plates 1GIN adjacent at least to the back wall, section space between the walls on p D: the longitudinal channels, the first group of electrodes, made in the form of plates, placed at the back wall along the entire length of the channels, the second group of plate electrodes placed between the electrodes of the first group and the front wall and made with holes located along the entire length of the channels, control electrodes for deflecting electrons moving between the electrodes of the first and second groups into these holes, cathode blocks for injecting electrons into the longitudinal channels between the electrons Dam of the first and second groups, located on one side of all the channels and a pair of control electrodes for the transverse deflection of electrons in the space between the second group of plate electrodes and the By the same wall, one of which is placed at one surface, and the other at the other surface of partitions, which bind each channels, the electrodes that are included in the above pairs are electrically interconnected. In addition, the electrical connection of the pairs of electrodes is carried out by two tires so that the pairs of electrodes connected to one bus alternate with the pairs of electrodes attached to the second bus. FIG. 1 shows the proposed device, a general view; FIG. 2 is a cross-sectional view A-A in FIG. 1. The device consists of a flask 1 with a front wall 2. and a rear wall 3. Between the walls there are partition walls kf dividing the volume of the flask by 5 "In the channels are located the lane. a group of plate electrodes 6 and a second group of plate electrodes 7 with holes for the passage of electrons from the space between the first group of electrodes and the second group of electrodes. Control electrodes 8 are placed in this space to deflect electrons into the apertures of the second group of electrodes. Control electrodes 9 are placed in the space between the second group of electrodes and the front wall. Except for the extreme ones, they are located on the side surfaces of the partitions. A phosphor coating 10 is deposited on the inner surface of the transparent front wall. On one side of the channels cathode blocks are placed, the power to which is supplied through connector 1-1. The device works as follows. The electrons from the cathode blocks enter the space between the electrodes 6 and 7 and move along the channels bounded by the partitions k. If it is necessary to deflect electrons, the required signal is applied to the control electrodes to the eco-electrodes, and the electrons through the holes in the electrodes 7 begin to move — on the side of the screen. At the same time, they are fixed and accelerated to the required energies. The accelerated electron beams are deflected across the channel with the help of electrodes 9. This is achieved by sweeping the beam across the channel. If it is necessary to obtain a color image, three electron beams can be used in each cell of the indicator. The proposed design and connection scheme of control electrodes 9 significantly reduces the power consumed by electrodes 9, as the energy for charging and discharging the capacitance formed by a pair of electrodes adjacent to one partition and the dielectric layer is reduced, because when this The pairs of essentially one electrode capacitance of a pair of electrodes is significantly reduced. Thus, the implementation of the proposed solution makes it possible to markedly reduce the overall power consumption devices. Claim 1. An electronic indicator device comprising an evacuated flask with a phosphor screen on the inner surface of the front wall, between the front and rear walls of which the partitions are placed in the form of flat dielectric plates adjacent at least to the rear wall dividing the space between the walls on a number of longitudinal channels, the first group of electrodes, made in the form of plates, placed at the rear wall along the entire length is indicated: These channels, the second group of plate electrodes, placed between the electrodes of the first group and the front wall and made with holes located along the entire length of the channels with control electrodes for deflecting electrons moving between the electrodes of the first and second groups into these holes, cathode blocks for injecting electrons into the longitudinal channels between the first and second electrodes groups located on one side of all channels, and a pair of control electrodes for lateral deflection of electrons in the space between the second group of plate electrodes and the front wall one of which is located at one surface, and the other at another surface of partitions, limiting the channels, characterized in that, in order to reduce the power consumed by the control electrodes, the electrodes included in these pairs are electrically connected between by myself. 2.
