Description

The invention relates to computing; 1; 1 technology and can be used in various systems for information processing and control. A device for displaying information is known, which contains an information input unit, one output of which is connected to the indicator board, the other to the register of columns, and the input to the information source. The inputs of the register of columns and row registers are connected to the address bus, one output of the register of rows is connected to the indicator board, and the second is connected to the output of the register of sectors, and the output of the register of columns and the register of sectors through the two output elements AND is connected to the indicator board having b; memory for storage | | 0many 1J. The disadvantage of the known device is that with increasing numbers; The space in the scoreboard is growing and the number of symbol formation circuits, and this leads to a decrease in the unit reliability of the device and an increase in its cost. The most bisexual to iipe ;;, iaracMo.iy is a device containing its concurrently connected signal, shift register, memory register, and keys, the biiix of which are connected to the ground of the plasma indicator inputs, to the other g 11che1I) 1 outputs of series-connected matrix distributor and Wuxi unit: P1te, 1st-formers, code conversion unit, one output of which is connected to the input of the buffer memory unit, and the second to one input of the control unit connected to another input adress counter output Sa, the corresponding outputs of the control unit are connected to the input of the buffer memory unit; a fragment counter and a counter up to E5, the temporal counter of the fragment counter and a row counter are connected to the corresponding inputs of the matrix distributor, and the output of the buffer memory block is connected to the input of the character generator 2. The frame of information is displayed in the device by sequentially displaying rows of elementary cells in the plasma indicator. The maximum number of rows of ziakomest in the scoreboard is determined by the following types of conditions. H series familiarity - the number of scoreboards; - the number of rows e; 1mentarpykh cells in the nlamenmenny indicator; - the number of horizontal fragments in one familiarity; the duty ratio of the supply voltage of the elementary cells in the plasma indicator is permissible. In this case, the memory register (shift register) register is defined by the expression. M pn, where M is the register resolution; and - the number of vertical fragments in one familiarity; p is the number of places in the board. The total register width is 2M. Thus, based on dependencies (1) and (2), for the board, having one K sign places, two M-bit registers are needed where K is the number of familiarity of the board. For example, with Rdog 50, p 5, K 126, we get M 90, i.e. two 90 bit registers are required. As can be seen, the volume of control equipment (registers) grows in direct proportion to the number of familiarity in the scoreboard. Accordingly, the cost increases and the reliability of the device decreases. The aim of the invention is to simplify the device by reducing the volume of the equipment used. The 11-target-1a target is achieved by the fact that a device for displaying information containing an indicator board, keys, character generator, serially connected address counter and data block, clock generator, row register, column register, c}) pulse generator, character generator inputs , the address, row register register, column register, us block are the device installation input, the information inputs of the data box are information inputs of the device, and contains the elements AND –RE, AND, OR divider hour Oy, one input of which is the installation. Input device m, and the other input is connected to the output of the clock and pulse generator, and the output of the frequency divider - to the input of the character generator and one of the inputs of the OR element, the output of which is connected to the counting input. the address counter, and the other input is from the output of the AND element, one of the inputs of which is connected to the output of the NAND element whose inputs are connected to the outputs of the memory block, which are also connected to the corresponding inputs of the row register and the register of columns, the outputs register strings are connected to the first inputs, and the outputs of the register of columns - with the second inputs of the corresponding pulse formers, the outputs of which are connected to the display elements of the indicator board corresponding to them, the outputs of the character generator are connected to the inputs of the keys, the outputs of which are connected to the corresponding elements of the indication elements familiarity indicator board. FIG. 1 shows a block diagram of the device; in fig. 2 - time diagram of his work. The device for displaying information contains an indicator board 1, character generator 2, keys 3, an address counter 4, a memory block 5, a register of 6 rows, a register of 7 columns, drivers of 8 pulses, an AND-HE element 9, an AND 10 element, a clock pulse generator 11 , frequency divider 12, element OR 13 device installation input 14 and informational device inputs 15. The device works as follows. After the initial installation, character generator 2 generates a code corresponding to the first character of the used alphabet. At the same time, the counter 4 addresses sequentially, with the frequency set by the generator AND clock pulses, selects the address codes recorded in memory block 5 of the address where the given symbol should be highlighted. These codes are copied from block 5 of memory into a register of 6 rows and a register of 7 columns. As soon as the inputs of the drivers 8 simultaneously receive signals from the outputs of the register of 6 rows and the register of 7 columns, it begins to generate a supply voltage pulse with the duration required for the type of display elements used. The period of the clock pulses is chosen so that it is negligible compared to the duration of the pulses Td j of the supply voltage of the display elements (T. ,, “T, y,) but sufficient to reliably sample data from the memory block 5 and to run shapers 8 pulses. As soon as the counter of the 4 addresses selects from block 5 a code signaling the end of the sequence of familiarity addresses on which this symbol should be highlighted, the signal from the output of the NAND block prevents the transmission of clock pulses from the generator 11 to the counting input of the counter 4 and thereby stops Further addresses from block 5. After filling in the splitter 12 frequency, a pulse appears at its output, switching the character generator 2 to produce the next character code. The same impulse through the elementsILI enters the counting input of the counter 4 addresses and it continues the sequential development from the block 5 addresses familiarity, where this symbol should be highlighted. The division factor of the divider 12 frequency is chosen so that the pulse period at its output is equal to the duration of the pulses produced by the driver 8 pulses. Thus, this symbol is displayed almost simultaneously on all specified familiarities. After generating the entire alphabet, the process of outputting a frame of information on the indicator board 1 is repeated from the beginning. A frame of information is recorded from the computer in block 5 in the sequence in which it is sampled from block 5 for display. In the proposed device, the display of a frame of information is carried out by simultaneously displaying a symbol on all specified familiarities with the sequential generation of symbols of the used alphabet. As a result, the restriction on the permissible duty ratio of the pulses of the supply voltage of the display elements extends only to the number of characters of the alphabet used {i.e. S where S is the number of different characters used in the alphabet) and does not limit the number of familiarity in the scoreboard, since each generated character of the alphabet can almost simultaneously be highlighted on any given number of familiarity in the scoreboard. This is achieved by the fact that the sampling time of one acquaintance (f TJ.H) is negligible. a little compared to the indication time of the symbol (.and.), (I am NU), and the pulse formers are triggered by short pulses of duration Tg. Since the proposed device uses a string-column addressing system of familiarity, the address register size is necessary (register of rows plus register of columns) is associated with the number of familiarity in the display as follows: M 2-K, where M is the total address register size; K - the number of familiarity in the scoreboard. For example, with K 121, we get M 22, i.e. a 12-bit row register and an 11-bit column register are required. Thus, in the proposed device, with the increase in the number of familiarity in the scoreboard, the volume of control equipment (registers) grows in proportion to the square root of familiarity number, in contrast to the known device, where the volume of control equipment (registers) grows proportionally to the square root of familiarity number, where the amount of equipment grows in direct proportion to the number of familiarity. With the same number of familiarity in the table, the proposed device requires a significantly smaller amount of control equipment (registers) in comparison with the known one, which will lead to a reduction in cost and increase its reliability.
