Abstract

The invention relates to computing technology and can be used in information display systems on gas discharge display panels (GUIs). The purpose of the invention is to simplify the device. The device contains GUI 1, keys of the first 2 and second 3 groups, row 4 and column 5 decoders, clock generator 6, first 7 and second 8 counters, adder 9, memory block 10, switch 11. The set goal is achieved by constructing an information board on a GUI, the device contains a switch and a memory block into which a word is written, the length of which is equal to the number of GUIs of the board, and the single bits correspond to the cells of the GUI to be excited. To eliminate the parasitic illumination of neighboring cells from the excited cell, the outputs of the sweep counters are re-connected. 2 Il.

The invention relates to computing and can be used in information display systems for building information. display panel for gas discharge indicator panels

The purpose of the invention is to simplify the device.

FIG. 1 shows a block diagram of the device; in fig. 2 shows the connection diagram for the gas discharge indicator panel.

 The device contains a gas discharge indicator panel (GUI 1, keys of the first 2 and second 3 groups, 4 row and 5 column decoders, 6 clock pulses, the first 7 and second 8 counters, adder 9, memory block 10, switch P.

The device works as follows.

With the arrival of the next impulse, a code is generated from the impulse generator 6 on the first counter 7, which is fixed to the 4-line decoder and decrypted by the GUI 1 string corresponding to this code. The outputs of the first counter 7 are re-connected, thus 30 the number of outputs of the memory block 10 is equal to

number of display panels.

Thus, with an increase in the number of gas-discharge indicator panels, the device practically does not require additional hardware costs and measurements, which distinguishes it from the known ones.

that the third bit is assigned a weight of –2 °, the fourth –2, the first 2, and the second –2. The content of the counter 8 is changed after each filling of the first meter 7. 35

Codes from the outputs of the counters 7 and go to the inputs of the adder 9, on you-. during which the code is formed, the transducer arrives at the 5 columns, and provides the connection of the column corresponding to the given code, all the o. steel columns are connected to the common bus and bypassed. The selection of rows and columns is organized in such a way that the influence on the operation of the device of transient processes on the ISU electrodes is excluded, because due to the re-switching of the outputs of the counter 7, the panel electrodes are selected through three, i.e. First, the first row eg and column are selected, then the fourth row and column-Etc, so the connection of the neighboring electrodes is significantly separated in time.

The outputs of the first counter and the adder 9 form the address for the block of memory 10, the outputs of the counter 7 are the lower address bits. Information on the specified address from block pa45
