Description

The invention relates to automation and computing technology and can be used in devices for displaying signographic information containing an alternating current matrix gas discharge display panel (HIP).

The purpose of the invention is to increase the speed of the device.

FIG. 1 shows a block diagram of the proposed device; in fig. 2 - time diagrams of the operation of the signal converter information in the write and erase mode; in fig. 3 - time diagram of the device.

The device for displaying information (Fig. 1) contains an gas discharge display panel 1 of alternating current, a bus selection unit 2 along the Y coordinate, a tire selection unit 3 along the X coordinate, generators 4 and 5

supporting voltage, respectively, on coordinates X and Y, shaper 6 write pulses - erase, distributor 7 pulses (synchronizer), converter 8 information signals, containing switches 9 and elements NOT 10.

The device works as follows.

The following signals are received from the external information system: an information code to the input of the converter of 8 information signals, a code for selecting a familiarity to the input of block 3 for selecting groups P1IN along the X coordinate, a code

selection of the line to the input of the bus selection unit 2 according to the Y coordinate. The information code defining the recording or erasing of the cell of the selected microstring (1 in the input signal means locking O - erasing)

letter

On one inputs of switches 9 and elements NOT 10, from the output of which the inverted sigals arrive at other inputs of switches 9, the input gates of switch 9 from the distributor 7 pulses (synchronizer) simultaneously with information signals receive recording gates and erasing gates. information from the record line to the output of the circuit, write pulses pass, and if the low level of the information signals coincides with the erase strobe, an erase pulse passes to the output (Fig. 2). Thus, at the outputs of the information signal converter 8, depending on the value of the input information signal, the write or erase control signals appear, which are fed to the inputs of the bus group selection unit 3 along the X coordinate. Simultaneously with the information signal of the familiarity code and code line distributor 7 pulses except strobes Records and erase generates the signals controlling the operation of the generators 4 and 5 of the supporting voltage and the driver 6 pulses write-stent. The alternating voltage generators produce alternating rectangular-shaped voltages supplied through blocks 2 and 3 of the bus bar selection to panel 1 electrodes. The write-erase pulser 8 generates a high-voltage recording and bar voltage, which is fed through the Y coordinate bar 2 on the rows of panel 1. Thus, for example, the first input of the address input of the group 3 for selection of groups shi1 enters, for example, eight signals of the content of the linear familiarity, to the second address input a four-bit binary selection code familiarity, the information input receives the voltage of the supporting voltage, which is converted in accordance with the signals of the content of the linear familiarity (Fig. 3). If it is necessary to set fire to the cell at the ISU (or to confirm its burning), then In the form of the impulse of the supporting voltage Ux, there will be no part, indicated in FIG. 3 and by the numeral k, if it is necessary to erase the cell (point) on the ISU (or confirm its deletion), then in the form of a pulse of the supporting voltage U, a subsidence is formed, indicated in FIG. For digital 1 and depending on the signal content of the linear familiarity for each point, the corresponding voltage goes to the columns of panel 1. At the same time, the parallel binary code for selecting the row is sent to the address input of the bus selector 2, the information input receives the supporting voltage pulses , to the control input - write-erase pulses. In accordance with the incoming code, a single bus is selected along Y, while a supporting voltage is formed on the selected bus with a voltage boost τ and a pulse n (Fig. 36), for the remaining buses a voltage is generated; ordinate Y, the supporting voltage is of a pulseless type. As a result, the following variants of the resulting voltage are possible at selected points of the working field of the GUI. (Fig. 3, d, d, e, g). In this case, the Sv option provides cell ignition (or burning confirmation), the Zg option provides cell erasure (or erasure confirmation), the options Back, e, f ensure the stability of the recorded information, i.e. support mode. For example, if at the first time point on the line (column) of panel 1 you need to display 8 points that must be lit through one (odd hot, even hot), then on odd cells of panel 1 in the same period of the supporting voltage, the resultant voltage of FIG. Sv, on even cells in FIG. 3 g, on the remaining cells of panel 1 of FIG. 3 d, e, g. If at the next time point it is necessary to change the information to the opposite, then on the odd cells, the resulting voltage of FIG. 3 g, on even cells in FIG. 3 in, i.e. change of information requires 2 periods of supporting voltage, while in the analogue of the frequency of the period, and in the prototype - sixteen periods of supporting voltage. Thus, in the device for displaying information, a method of updating information in the microstring (line) for one period of retaining voltage is implemented, which allows increasing the speed of information change.
