Description

The invention relates to information technology and can be used to create display devices for graphical and histogram information. The aim of the invention is to simplify the device for displaying information. Figure 1 shows the functional diagram of the device; Fig. 2 illustrates stress plots. The device contains (Fig. 1) memory block 1, block 2 for sampling horizontal buses of the gas-discharge display panel 3, block 4 for sampling vertical buses, first switch 5, scan counter 6, generator 7 clock pulses, second switch 8, address register 9. Figure 2 shows the plots of the sync pulse (a) and the half-voltage of the first (b), second (), third (d), fourth (c)) and last W (e) columns (the display element of the third column is greater than brightness); moreover, t is the duration of the pause between column selection pulses, and t is the duration of the control pulses applied to the selected column during the pause. The device works as follows. The incoming information to the device is recorded in block 1 of the recording pulse memory. The addresses of the memory cells of block 1, to which information is recorded, are specified by the address register 9 and arrive at the address input of memory block 1 via the switch 8 during the presence of a firing pulse. At the end of the recording pulse, the information recorded in block I is displayed on indicator 3 as follows. The pulses coming from the first output of the generator 7 clock pulses, switch the counter 6 sweep. The code signal from the output of the counter 6 through the first switch 5 is fed to the vertical sampling unit 4, which connects the corresponding vertical electrode of the GUI 3. Codes supplied to the vertical bus sampling unit 4, one, are received through the switch 8 at the same time and to the address inputs of the memory 1 , providing at its outputs signals recorded at this address. The output signals of the memory unit 1 are fed to the horizontal busbar sampling unit 2 and cause the appearance on the horizontal panel electrodes 3 pulses that control the excitation of the corresponding display elements. The allocation of information recorded in memory block 1 by the brightness at the address corresponding to the state of register 9 is carried out as follows. In order to ensure reliable operation of panel 3, technical specialists are advised to provide a temporary pause between the switching on of adjacent scanning electrodes when they are scanned for a duration of 5-10: µs. Time to be paused is suggested to be used for additional excitation of the display elements of the selected column. The pulse from the second output of the clock generators 7 is controlled by a switch 5, the output of which during a pause appears code signals corresponding to the state of register 9 of the address. The signals provide the output to the indicator 3 information of the selected column. The duration of the pulses controlling the excitation of the elements of the display elements of the selected column is also small. For a reliable excitation lix, conditions must be created that significantly reduce the ignition delay, and in all cases the static component must be sued; This is ensured by reducing the period of the excitation pulses to a value shorter than the recovery time, and setting one of the electrical strength of the gas discharge gap. The recovery time of the electrical strength of the gas-discharge indicators produced by the industry is 1-1.5 ms, the formation time 1-; and the discharge 1-7 of the ISS. Therefore, the supply of control pulses to them is less than g; 1-: those of pause 1 provide additional excitation of the display elements of the selected column, the coordinates of which correspond to the code from the register 9 address output, And since the number of such im.chulums can be equal to the number of vertical electrodes (FIG. 2 ), then the brightness of the selected column can be applied in a large range of capacities, by changing the number and duration of the columns. Thus, the device, together with the display of 1 pa.m recorded in the block, the hygienicipt provides for the selection of the display elements of the column, whose address is determined by the code signal from the output of address register 9, by the brightness.
