The invention relates to automation and computing and can be used in information display systems containing a gas discharge direct-current display panel.

The purpose of the invention is to increase the reliability of devices and due to reliable

excitation of gas discharge intervals of the time of formation of the discharge in the gas

first sweep electrode at nominal field voltage.

The drawing shows a block diagram of a device for displaying information.

The device contains a block 1 for sampling lines, a gas-discharge indicator panel 2, a block 3 for scanning, elements AND 4, a driver for 5 pulses, elements OR-NOT 6, inputs 7-9.

The device works as follows.

The input signals of the displayed information, coming through the input 7 of the information signal to the row sampling unit 1, change the signal level at the outputs of this block, thus driving the necessary display elements of the gas discharge display panel 2. The image is scanned by the sweep unit 3 controlled by code signals sweep coming at the input 8 of the sweep control through the element 4. The sweep codes arrive at. block 3 sweep in the presence of the first inputs of the elements And 4 signal Log.1, coming from the inverse output of the imaging unit 5 pulses. The input information is synchronized with the image scan.

The signal from the direct output of the imaging unit 5 is fed to the second inputs of the elements OR-NOT 6, the outputs of which are connected to the control inputs of the block 1 for sampling lines 1 and are used to display additional information, such as scale lines, marker, etc. The appearance of the signal at the control input 9 of the auxiliary bit of the block 1 for sampling the rows leads to the excitation of the discharge in the display element.

The reliability of displaying information in the initial image sweep region is ensured by the excitation of an auxiliary bit on the first sweep electrode with a period shorter than the electrical strength of the gas discharge gaps. The period of access to the first sweep electrode is set by connecting the input of the imaging unit 5 to one of the control inputs of the second group, and the time of the circulation - by the timing parameters of the imaging circuit of the imaging unit 5. The circulation time must be longer

bit intervals determined by the indicator parameters.

A pulse with a level of Log.O at the inverse output of the imaging device 5 and 5 pulses affects the elements AND 4 so that at their outputs and, accordingly, at the inputs of the scanner 3, a code signal of the first scanning electrode appears, which provides

0 selection of the first electrode of the gas discharge indicator panel 2.

Simultaneously, a pulse with a level of Log.1 at the direct output of the imaging unit 5, arriving at the second inputs of the elements OR-NOT 6, ensures that all the control inputs of the block are sampled rows of signals that cause the excitation of a discharge in all elements of the first column display

0 select this column. The next return to the gas-discharge gaps of the first column is made with each change from a low to a high signal on the bus line to which the driver 5 is connected.

The excitation of the auxiliary discharge on the first sweep electrode, in the gas discharge gaps of which the deionization process is not completed and there are charged particles, reduces the time lag of the occurrence of the discharge to the time the discharge is formed. Therefore, the initial portion of the scan image appears

5 constantly ready to display information.

Depending on the image scanning frequency on the gas discharge indicator, the code change frequency changes;.

0 sweep and, accordingly, the frequency of reference to the first sweep electrode. The recovery time of the electrical strength of the gas-discharge gaps is almost unchanged, therefore, in order not to contact the first sweep electrode too often, the input of the pulse shaper 5 is connected to that sweep code line, change, level 5

0

n signal at which occurs with the period closest to the desired.

Thus, the device provides a reliable display of information on the gas discharge display panel when the gas discharge gaps of the first sweep electrode are energized by a nominal voltage.
