familiarity addresses in the position code. Familiarity is a group of cells lying at the intersection of eight horizontal and eight vertical electrodes 2 GIL 1. For IGPV1-512 / 512 type GUI 1, the number of familiarity for each coordinate is 64, Therefore, to address 64 familiarities for each coordinate, six-digit are needed. parallel binary address code for X and Y, which is written in address register X 14 and y 15 ..

pulses, where n pulses of standard duration and frequency are formed, shifted relative to each other by pulse duration. From these pulses, pulses of a certain duration are formed on the driver of the 38 pulses, which control the operation of the pulse generator 7. The duration of the control pulses and their supply time to the pulse generator 7 are determined by the pulses received at the first output from the pulse former 41, the second input of which receives certain frequencies from the frequency divider 36, and the first input the mode code from the decoder 40.

In the graphic information recording mode, information about this mode and graph coordinates is fed to the corresponding inputs of the X 14 and Y 15 registers, mode 39, line 9 and column 12.

In accordance with the mode code received from the mode register 39 and decoded by the mode decoder 40.

, pulse generator 41 generates pulses that allow the passage of information address codes from the corresponding address registers X 14 and Y 15

in these cells when they are once ignited.

The pulse generator 7 is controlled by a synchronizer 8 .. From the master oscillator 35 (FIG. 4), the clock frequency is supplied to a frequency divider 36, where it is divided into a frequency for maintaining the discharge.

Frequency divider 36 is performed on a binary counter. The code with the divider 36 frequency goes to the decoder 37

address decoders X 5 and Y 6 through the element AND 21 n element OR 20 address converters in the coordinates X 18 and Y 19. Resolution pulses to the second inputs of the elements And 21 come from the synchronizer on the fourth and seventh outputs. In accordance with the address code, address decoders X 5 and U 6 are implemented using selection blocks. tires on the coordinates of X 3 and Y 4 a sample of eight electrodes of the ISU 1 along the coordinates of X and Y, forming at the intersection one familiarity.

The information in this familiarity is recorded in accordance with the information received from the register of rows 9 to the bus selection unit at the coordinate YA through the element OR 10. The selection of the column containing the information about the chart is carried out through the switch 24 of the position code converter by coordinate X 17 block selection of women in the coordinate X 3.

When writing to the selected rows and columns of the ISU 1 from the pulse generator 7, ignition pulses are fed through the tire selection units along the coordinates X 3 and Y 4. The ignition (switching on) of the selected cells occurs, accompanied by luminescence.

In the mode of writing a small sign, information in the form of binary codes arrives at the registers of mode 39, sign 33, addresses X 14 and Y 15.

The selection of familiarity occurs in the same way as in the mode of recording graphic information.

When a small sign is formed from a register of 33 characters, it goes to a block of 32 characters memory, which entails (Fig. 5) a sequence of position codes of rows 42 to a converter of positional code according to coordinate Y 16 and codes of columns of a sign on column 12.

The position codes of the lines 42 pass through the switch 24 (FIG. 2) of the position code converter according to the coordinate Y 16 when it coincides on the AND 27 elements with the small sign gate 4 arriving at the second inputs of the AND elements 27 of the switch 24 from the forma 41 pulse synchronizer 8. Then this code passes through the elements ifflH 30 and along output bus 3 through the element OR 10 enters the bus selection unit according to the coordinates U 4, which makes a sample of electrodes 2 according to the coordinate Y in the familiarity place. At the same time, the codes from register 12 columns arrive at the decoder 11 columns, where they are decrypted into position codes of columns 44, which through the AND elements of the switch 24 and the OR elements 30 of the position code converter along the X 17 coordinate, through the output bus 31 arrive at the block selection of tires by the X coordinate 3. This block makes a sequential selection one by one

a column in the selected familiarity. Ignition pulses are supplied to the selected electrodes from the coordinates X and Y from the pulse generator 7. As a result, a sign is displayed on the GUI 1 at the selected address (see Fig. 6). The shape of the mark is chosen purely conditionally. The element of the mark is the single cell of the ISU 1.

In the recording mode, the middle sign of information with the sign of the middle sign in the form of binary codes is transferred to the registers of mode 39, the sign 33, addresses X 14 and Y 15..

The formation of control pulses and the selection of familiarity are carried out in the same way as in the recording mode of a small enac.

When an average sign is formed from a register of 33 characters, the code of the character goes to memory block 32, which, in accordance with the sign of the middle character, entails (Fig. 7) the sequence of position codes of rows 42 to the positional code converter according to coordinate 16 and codes of columns of the sign to register 12 columns. In this case, the frequency of the pulses fed to the counter 34 of the pulses of the character generator 13 from the second output of the synchronizer 8 is two times lower than when writing a small sign.

The position codes of lines 42 arrive at the second switch 25 of the codes of the position code transformer according to the coordinates Y 16. Initially, the position code 42 of the first four lines passes through the elements 27 of switch 25 when there are two signs of the first gate at the second inputs. Then the positional code of the first four lines passes through the elements OR 28, the elements OR 30 and the output bus 31 through the element OR 10 enters the bus selection unit according to the coordinate Y 4, which makes a sample of electrodes 2 according to the coordinate Y in the selected place .

At the next stage of forming the middle sign, the address code of the familiarity in the Y coordinate is increased by one. At the same time, the shift code 46 through the third output of the synchronizer 8 from the pulse generator 41 is summed on the adder 23 from the address code at Y and goes through the element AND 22 n element OR 20 to the address decoder, at. Coordinate Y 6. In a similar way, the tracking code 42 of the next four rows of the selected column is passed through and the second four elements AND 27 of the second switch 25 of the second gate U of the middle sign 47 are present at the second inputs.

Simultaneously with feeding through the element OR 10, the tire sampling unit along the Y coordinate 4 positional code of rows 42, the decoder 11 columns from character generator 13 receives the column code, where it is decrypted into the positional code of column 44, which is fed to the positional converter of the position code along the X coordinate 17, whose operation is similar to the work of the positional transducer, the code, according to the coordinate U 16.

At the same time, the length of the first 48 and second 49 columns X of the middle character and shift code X 50 is eight times longer than that of the Y coordinate. Moreover, after selecting four columns of the double digit, the address code along the X coordinate is increased by one on the adder 23 of the address converter by X coordinate 18. The shift code to the address transformer to the X coordinate 18 comes from the synchronizer on the sixth output.

Ignition pulses are supplied to the selected electrodes from the coordinates X and Y from the pulse generator 7. As a result, on TYPE 1, the middle sign is highlighted at the selected address and character code (Fig. 8). The shape of the sign is chosen conditionally. The element of the middle mark is four cells, lying at the intersection of two vertical and two horizontal electrodes 2.

In the recording mode of a large sign of information with a sign of a large sign in the form of binary codes, it enters the registers of mode 39, sign 33, addresses X 14 and U 15 ,.

The formation of control pulses and the selection of familiarity are carried out in the same way as B; modes of recording small and medium characters.

When forming a large sign, the zyak code from the register of 33 characters goes to a block of 32 characters memory, which, in accordance with the sign of a large sign, causes (FIG. 9) a sequence of position codes 42 from the position code Y transducer according to the Y coordinate 16 and codes

sign columns on register 12 columns. In this case, the frequency of the pulse input to the pulse counter 34 is two times lower than when recording the average sign. The position codes of lines 42 (FIG. 9) are sent to the switch 26 of the codes of the converter of the position code along the Y coordinate 16. The position code 42 of the first two lines passes through the elements 27 of the switch 26 when there are the first inputs of the second inputs of the second gate of the large sign 51, post - a pan-clock from the ninth output of the synchronizer 8. Then the position code 42 of the first two lines passes through elements 29 and 30 OR and, via output bus 31, through the element OR 10 enters the bus selector unit according to the coordinates U 4, which makes a choice 2 on the Y coordinate selected familiarity. After this, the address code of the familiarity on the Y coordinate is increased by one. In this case, the shift code Y 46 comes from the synchronizer 8 on the third output, is summed on the adder 23 with the address code on Y and is fed through the element And 22 and the element, OR 20 to the address decoder along the coordinate Y 6,

In a similar way, passing and pairing a sample of positional codes 42 of the next six rows of the selected column is performed when the second signatures of the And 27 elements of the switch 26 of the second 52, the third 53 and the fourth 54 gates are fed to the large sign from the ninth output of the synchronizer 8.

A selection of large digits columns is provided by feeding from the tenth output of the synchronizer 8 to the inputs elements OR 29, respectively, of the first 55 and second 56 gates X of the big sign. Moreover, after selecting the first two columns of the displayed character, the address code along the X coordinate is incremented by one for each new sample of the next two columns. This is ensured by applying to the adder 23 shift codes X 50 on the sixth output from the synchronizer 8. On the selected electrodes 2 familiarity from the coordinates X and Y from the pulse generator 7, igniting pulses are applied. As a result, a large sign is displayed on the GUI 1 at the selected addresses and character code (Fig. 10). The shape of the sign

wound conditionally. A large sign element is sixteen cells lying at the intersections of four vertical and four horizontal electrodes 2.

Thus, the proposed device allows the formation of signs of specified sizes, in particular, with 5x7, 10x14, 0x28 formats in familiarity with the decomposition of 8x8, 16x16 and 32x32 cells, respectively. In addition, with each increase in the scale of the sign, the thickness of the contour of the sign doubles.
