The invention relates to automation and computing and is intended to display information on matrix indicators made on two-color elements.

The aim of the invention is to improve the speed of the device.

The drawing shows a block diagram of a device for displaying information on a gas discharge display panel.

The device contains the first 1 and second 2 memory blocks, the geerator of 3 pulses, the first 4, second 5 and third 6 counters, multiplexer 7, switch 8, first element 9, first 10, second 11, third 12, fourth 13 and fifth 14 registers, the first, second and third groups of keys 15, 16 and 17, the gas-discharge display panel 18 and the decoder 19, the second element I 20, information input 21, device address input 22, first and second control inputs 23 and 24 devices.

The device works as follows.

The image object is divided into sections. Each section is a page from the first memory block 1. The page is stored in the form of a display element with the signs to shine or not to shine. For each strand of the first memory block, a second cell is indicated in the second memory block 2 indicating the desired depth of the section. By using the information of two memory blocks, it is possible to construct a three-dimensional image without machine preparation of the second projection, which accelerates and simplifies the procedure for synthesizing a three-dimensional image.

Synchronously with the preparation of the next page line using the fifth register 14 and multiplexer 7, the required offset value of the projection of a point of one color relative to the projection of a point of another color is automatically provided. On the gas discharge display panel, rows of different colors alternate through one.

The device operates in two modes: recording the input information into the corresponding cells of the first or second memory blocks and displaying information from the first memory block on the discharge panel 18 for controlling the signals from the second memory block.

In the recording mode, information about a point or a group of points is sent to the device information input 21 to record information about the corresponding cross-section of a three-dimensional image, the address code of the cell to be selected is sent to the device address input 22, and the write control pulse is sent to the first control input 23 of the device. At this, the control signal connects through the second element AND 20 the first information input of the multiplexer 7 to; output. Similarly, the recording of the section depth code in the second memory block occurs. But in this case, recording takes place on a pulse applied to the second control input 24 of the device.

In the mode of displaying information. On the first 23 and second 24 control inputs of the device, a pulse is absent and a single signal from the output of the second element I 20 connects to the output of multiplexer 7 a second electronic input. Thus, the first I and second 2 blocks of memory are supplied with an address code of counters 4.5 and 6. A pulse generator 3 starts the first 4, second 5 and third 6 counters connected in series, which synchronize the operation of the entire device. The signals at the information outputs of the first 4, second 5, and third 6 counters are the address codes of the points in the row, the lines in the frame, and the page in the entire array with the corresponding cell indicating the section depth code in this page. The address code of the row in the frame from the outputs of the second counter 5 simultaneously enters through the decanter 19 on the keys of the second group 16 and selects the corresponding vertical bus with the discharge indicator panel. Thus, using the second counter 5 lines, the decoder 19 and the keys of the second group 16, the vertical buses of the gas discharge indicator are sequentially searched. on the control panel 18. The digital code from the information outputs of counters 4.5 and 6, coming through multiplexer 7 to the address inputs of the first memory block 1, displays information about the current point from it (sign to shine or not to shine). This signal arrives at the information inputs of the first register 10 and p that register 14. The clock outputs of registers 10 and 14 receive a signal from the generator of 3 pulses, which shifts the information in them by one step. The function of the switch 8 is to transmit to the information input of the third register 12 a signal from the output of the fifth register 1A indicated by the signals at the control input of the switch 8 representing the depth code of the section, depending on the number of the connected information output of the fifth register 14, information at the input of the third register 12 is delayed with respect to the information at the input of the first register 10 by the number of clock cycles N6 D N the number of the output of the p register 14 connected in this frame; n - their total number. After filling in the information about the next row of registers 10 and 12 with a pulse from the transfer output of the first counter 4, the second and fourth 13 registers are overwritten and the voltage is applied to the horizontal buses of the gas discharge display panel 18 via the keys of the first 15 and third 17 groups And 9 the fifth register 14 has zipped and the device will be ready to process the information to indicate the next line. Similarly, all rows of the same section are processed. Switching the display to the next section is performed by a signal from the second output of the second counter, which registers 10, 12 and 14 are zeroed in and the address of the page is increased by one. In this way, the indicator elements of the panel are sequentially excited and the information recorded in the first memory block 1 is displayed.

In the device, the volumetric image is synthesized on the basis of one projection, information about which is in the first memory block, by adjusting the time shift according to the data recorded in the second memory block. The introduction of simple hardware blocks eliminates the need for machine generation of the second projection, which reduces the time of preparation and exchange of information between the computer and the device, thereby increasing the speed of the device.
