with a computer, the first output - with the information input of the matrix screen 11, and the third output - with the first inputs of elements 7 - 7 I.

The current register is used to record and store the address of a string. The first input of the register b of the row is connected to the computer, the second input is connected to the output of the element And and the second input of the control unit 1, and the outputs to the current inputs of the matrix ec0 P, n

Elements 7-7 And in combination with the p-bit register, the 8-column register, which is a normal register with parallel recording and information output and separate installation inputs to the zero state of each of the bits, is intended to store and store the logical scale of those indication cells in the selected line of the board, information in which is updated in the current recording cycle,

and forming a sampling signal of the next of these cells by sequentially. entering ipformatization. The first input of register 8 columns is connected to a computer, the zero output of each i-ro digit of the register of column 8 is connected to the single-element from the inputs of each successive element -7 I, the unit output of each i-ro digit of register 8 columns is connected the second input of the corresponding element E of element 7 I, the output of which is associated with the corresponding input of the matrix screen 11 and through element 10 of the delay from the input of the reset of the i-bit of the register of the 8 column and one of inputs e, tementa OR 9.

Element 9 OR and delay element 10 -10 are used to generate signals for the end of the sign recording to the next indication cell. Element output 9 OR is connected to the third input of control unit G.

The matrix screen 1 is designed to display the recorded chi and and the puncture and.

5 The device operates as follows. In the initial state, all the registers and trigger of the device are in the zero state, and a single signal from the zero output of the trigger signals the computer that the device is ready to receive information. To enter information into the device for display from a computer, a command is selected to select a row of the matrix screen, which sets the register bit row to one, corresponding to the row of the matrix screen, and all bits of the register are 8 columns, corresponding to the selected row, display cells which should be updated information.

Then, by a command for recording information from a computer, a sign code is entered into the register 5 of the character of the control unit 1. In this case, at the output of element 4 I, PI, a signal for selecting the indication cell is generated, which is fed to the single input of trigger 2, the device is ready to receive information, and to the first inputs of elements 7-7 I. Only one of these elements, namely the first one, is removed. 8 bits of register register set to one state, this turns out to be open on all inputs, since the AND elements preceding it are closed by signals from single outputs set to the zero state of register bits of the 8 column, and after the next ones are closed by a signal from the zero output of the corresponding register bit set in one state. At the output of the open element And formir; A signal which is fed through a corresponding column bar to the matrix screen 11, as a result of which the display cell, located at the intersection of the excited row and column women, is prepared to receive information.

At the same time, the code converter 3 of the control unit 1 converts the sign code received from a computer into an illumination code, feeds it along the information bar to the matrix screen 11, where it is written into the display cell prepared for receiving information.

After a certain time required to record the sign in the display cell, the signal from the output of the open element And delayed by the delay element for this time goes to one of the inputs of the 8th column register, sets the corresponding bit to the zero state, and through element 9 OR - to the reset input of the register 5 characters of the control unit 1, causing the latter to clear the indication cell selection signal.

To record each successive character of the selected line from the computer, a command is again sent to record information on which the described cycle of operations is carried out, with the result that the information coming from the computer is written into the corresponding cells of the selected row of the matrix screen 11.

After the information has been written to the last cell of the display of the selected row of the matrix screen 11, the output of the update of the selected row of the matrix screen 11 is set, which sets the register of row 6 to zero and generates arrives at the zero input of the trigger 2 of the control unit 1, forming at the zero output its unit readiness signal of the device to receive information for the next row of the matrix screen 11.

To update the information in the next row of the matrix screen 11 from the computer, the command to select the display row is again sent.

The process of updating information in this and subsequent lines proceeds as described. The new execution of the control unit, the introduction of additional delay circuits and new connections, when using display cells to display both dynamic and static (for a certain period of time) information, perform progressive automatic selection of only those display cells, in which information is to be updated. in the current recording cycle, and thereby speeding up the process of updating the displayed information and increasing the efficiency of presenting it to users.
