The invention relates to computing and can be used for outputting information from computers. A device for displaying information / containing a transparent plate, successively coated with transparent electrically conductive and deformable layers, is a metal fiber plate, on both sides of which a perforated electrode is applied, one of which is coated with a photoconductive layer, and the other is a resist. A device for displaying information is also known, comprising a recording and erasing illuminant, a recording and controlling unit of a deformable layer consisting of parallel-installed dielectric plates with transparent electrically conducting layers on their source, moreover, the photoconductive layer is applied to the electrically conductive layer of the plate facing the cooling rotor, and the deformable layer 23 is applied to the electrically conductive layer of the other plate. is unsatisfactory reliability. The closest to the technical essence of the invention is a device containing a recording and erasing illuminator, two transparent dielectric plates with transparent conductive layers on their inner sides, and an electrically conductive layer of the plate facing the illuminator consists of separate parallel-arranged conductors of rows and is covered with a photo-conductive slab, on an electrically conductive layer of another plate Annecy deformable layer and write and erase illuminator comprises a scanning imaging layer on photosemiconductor column located Nogo at right angles to the row conductors connected to the signal generating unit. A disadvantage of the known device is low reliability due to the use of a mechanical scanning unit and low sensitivity to control signals. The purpose of the invention is to increase the reliability of the display device. information with memory. The goal is achieved by the fact that in a device for displaying information with a memory containing two parallel-installed transparent dielectric plates, the inner surface of the first of which is applied in series with a transparent conductive layer and a gel-like deformable layer, and the column electrodes orthogonal to row electrodes, column electrodes are deposited on an insulating transparent layer deposited on a discharge transparent electrically conductive a layer deposited on the surface of the second transparent dielectric plate ,. the pair of coaxial holes are made in the second transparent dielectric plate and in the column electrodes, insulating transparent dielectric layer and discharge transparent electrically conductive layer, in the first of which are installed discharge electrodes made in the form of fibers of conductive material penetrating the second transparent dielectric plate strings with corresponding electrodes. Figure 1 shows the proposed device; figure 2 - section a "a in figure 1. The device comprises a first dielectric transparent plate 1, covered with a transparent conductive layer 2, on which a gel-like deformable layer 3 with a thickness of 10-100 μm is applied. In parallel with the plate 1, a second dielectric plate 4 is installed, which is penetrated by the fibers 5 of the conductive material. On the outer side, the plate 4 is covered with electrodes of rows b in contact with the fibers 5. On the inner side, the plate 4 is sequentially covered with a discharge transparent conductive layer 7 and an insulating transparent layer 8, the layers 7 and 8 being made with holes 9 around the fibers 5. On layer 8 is applied 10 column electrodes orthogonal to the electrodes b. The row signal generation unit 11 is connected to the electrodes 6 and layer 7 and serves to create an ion cloud in the holes 9. The column signal generating unit 12 is connected to the electrodes 10 and layer 2. The device operates as follows. Block. 11 generates a high-frequency electrical signal on one of the electrodes b and layer 7. As a result, a discharge occurs between the fibers 5 belonging to this electrode and layer 7, as a result of which an ion cloud forms in the opening 9. Block 12 applies voltage to those electrodes 10, the intersections of which with electrode b correspond to the presence of a unit in the displayed military signals. On the remaining electrodes b, a voltage equal to zero is applied. In the region corresponding to

in the presence of a few%, an electric charge is deposited on the surface of layer 3. By successive formation of a high-frequency signal on

; electrodes b and applying voltage to electrodes 10 receive a charge distribution in the plane of layer 3, c6, corresponding to the recorded information. Charges / deposited on layer 3 induce charges of opposite sign on layer 2. These charges create an electric field, the intensity of which depends on the charge charge deposited on layer 3. As a result, the electric field on layer 3 on its free the surfaces form a geometric relief, which can be maintained for a long time. The maximum storage time of the recorded relief

depends on the magnitude of the deposited charge and the PROPERTIES of layer 3. The duration of the storage time of the recorded relief can be adjusted by changing the electrical resistance of layer 3 and changing the voltage on

; column electrodes, since the voltage of a well determines the density of the charge deposited on the gel. deformable layer. The recorded resolution of layer 3 can be reproduced in the form of an optical image using known devices of slit optics.

The thickness of the deformable layer 3 is not less than half the spatial period of the

0 dov columns, the holes around the fibers 5 are made with a diameter of 0.4-0.25 spatial period of the electrodes, and the air gap between the plates is 0.1-0.5 thickness de

5 formed layer ..,

Deposition of charge directly onto a deformable gel-like layer, which allows the device to increase sensitivity by more than 3 times
