Description

The invention relates to a technique of recording information on deformable layers by the method of electrography, can be used to display information, and is an improvement of the known device according to the main author. No. 1149205.

The purpose of the invention is to improve the reliability of the device and the quality of playback.

FIG. 1 is a diagram of a relay device for optical display of information; FIG. 2 is a schematic diagram of the inclusion of information erase electrodes.

The relief device for optical information display contains a transparent dielectric plate 1, successively covered with tape transparent electrodes 2 and a deformable gel-like layer 3. Additional transparent electrodes 4 located parallel to the surface of layer 3 on an additional transparent plate 5 are located above the surface of the gel-like layer 3. Transparent tape electrodes 4 electric D1Ya 2 are connected to the generator of the information field 6. Electrodes 4 are located in the intervals between the electric s 2 along the optical beams and are connected with the alternator erase zapk- B 7.

The optical reproduction system consists of an illuminator 8, a capacitor 9, two slotted grids 10 and 11, a cylindrical objective lens morphote 12 and a scanning element 13 behind which the screen 14 is placed. At the same time, the write erase generator consists of 15 delay lines whose inputs are connected to corresponding to the electrodes 2, and the outputs to the corresponding electrodes 4 (figure 2). As lines 15 delays can be used, for example discrete elements.

The proposed device works as follows.

From the generator, information field 6, electrical signals are simultaneously supplied to all even-numbered electrodes 2 and to the inputs of the respective delay lines 15, and all odd-numbered electrodes 2 slow down at this time. Under the influence of an electric field, a geometric relief emerges on the surface of a gel-like deformable layer 3. Sections of a gel-like

layer 3 is selectively deformed in accordance with the magnitude of the electrical signals supplied to each even-num electrode 2. In this case, one line of the image is recorded. The delay lines 15 delay the signals until the end of the line recording, after which these signals simultaneously arrive at the even-erase electrodes 4, and the odd electrodes 4 at this time are grounded. When this occurs, the forced alignment-erasing of the resulting selective deformations occurs. As a result of forced alignment — the wiping of the resulting selective deformations by the signal itself, there are practically no parasitic deformations when recording signals with different amplitudes, which leads to an increase in the playback quality of the write-erase cycle of the recorded line. When recording elements in the next line from the information field generator 6, the signals are simultaneously fed to the odd electrodes 2, the even electrodes 2 are grounded at this time point. Selective deformations of the gel-like layer 3 are formed under the odd electrodes 2, which are forcibly erased by the same signals coming through the delay lines 15 to the odd electrodes 4, the even electrodes 4 are grounded at this moment. The second line is erased, etc.

Selective deformations of the gel-like layer 3 under the electrodes 2 are visualized as a line on the screen 14 as follows. The light of the illuminator 8 is deformed into a parallel luminous flux by a capacitor 9, which passes the direct grating system 10 and hits the opaque rods of the grating 11. In the absence of a geometric The relief on the free surface of the deformable layer 3 of the light point, passing through the slit of the grating 10, is completely overlapped by the rods of the grating 11 and there is no image on the screen 14. When electrical signals are applied from the generator of the information field 6, a geometric relief is formed on the free surface of the gel-like layer 3, which modulates the luminous flux incident on it. The modulated luminous flux passes through the gaps between the rods of the grid 11.

The anamorphic lens 12 compresses the relief image below the electrodes 2 and forms the image of the line on the screen 14. Using the scanning element 13, an image frame is formed.
