The invention relates to automation and computing, in particular, to systems for displaying sign information on a gas discharge display panel,

The purpose of the invention is to increase the information content of the device.

Fig. 1 is a block diagram of a device for displaying information; Fig. 2 is a diagram explaining the principle of arranging several windows from a large information frame on the menopih information dimensions screen.

The device (fig.O contains the first counter 1, memory block 2, character generator 3, second 4, third 5 and fourth 6 counters, decoder 7, pulse generator 8, first 9 and second 10 registers, groups of keys 11 and

12, gas discharge display panel

13, third 14, fifth 15, fourth 16, 01st 17 registers, first f8 and second 19 adders, first 20 and second 21 comparison blocks, element ShMNK 22, one-shot 23, element ShSh 24, third 25 and fourth 26 blocks comparison, the seventh 27 and eighth 28 registers, information input 29 of the device, address input 30 of the device. Fig. 2 indicates: 31 is an information frame stored in memory block 2, 32 is a gas discharge display panel screen, 33-36 are the first to fourth display fields, respectively, 37-44 are the X and Y coordinates of the screen origin in the coordinate system of the information frame when displaying the first, second, third and fourth display fields, respectively.

The device works as follows

In the memory block 2, an information frame is recorded via the information input 29 of the device at the addresses from the address input 30 of the device from the computer. After recording, the output of the first counter 1 is the address of the code of the currently processed character. The output of the second counter 4 together with the output of the memory block 2 is the address of the character decomposition element in the character generator 3. The signals from the output of the generator 3 increase or decrease the content of the third 5 and fourth 6 counters, in which the X and Y coordinates of the point being processed are stored .

Further, it suffices to consider the operation of one channel X, since the operation of channel Y is similar. The signals from the output of the third counter 5 are fed to the first information inputs of the first adder 18, the first 20 and third 25 comparison blocks, the second information inputs of which receive signals from the outputs of the third 14, fifth 15 and seventh 27 registers that store the X coordinate respectively. the position of the screen origin in the coordinate system of the entire frame; the lower and upper boundaries of the X coordinate of the displayed field. Moreover, in registers 14 and 16, the coordinates are stored in an additional code. The first adder 18 calculates the difference between the current coordinate X of the processed point and the coordinate X of the position of the screen origin in the coordinate system in this frame and transmits the result to the input of the first register 9, the signals from the outputs of the first 20 and third 25 blocks. Comparisons determine the output of the current coordinate for the lower and upper bounds of the displayed one, respectively, the floor (G is the sign of the output of the border of the displayed field) and go to the first and second inputs of the W-NE-22 element. The third and fourth inputs of the W-W-22 element receive similar signals. from channel U, in case of absence. a tecup (coordinates for the displayed field at the output of the SHS-PE 22 element, whose first input receives a strobe signal from the output of the OR 24 element, appears to write to registers 9 and 10 and start the one-shot 23, The signal from the output of the single-oscillator 23 enters the second input of the element OR 24 and prohibits the passage of pulses from the generator 8 to the second counter 4 at the time of issuing point information from registers 9 and 10 through groups of keys 11 and 12 to the gas discharge display panel I3 and igniting the cell. all elements decomposed Neither the second counter 4 sign by the signal at the first output increases the content of the first counter 1. The information about the coordinates of the position of the screen origin in the coordinate system of the entire frame, as well as the values of the lower and upper bounds of the displayed field from the computer come through the information input device 29 informational

inputs of registers 14, 15, 16, 17, 27, and 28. The choice of registers 14, 15, 16, 17, 27, and 28 or memory block 2 determines the signals at the outputs of the decoder, depending on the signals at address input 30 of the device. Before displaying the first field, bounded by the borders of the window 33 (Fig. 2a) at a given location of the screen 32 (Fig. 2b), the coordinate values 37 are entered into the registers 14 and 16

. and 38 positions of the origin of the screen coordinates, in registers 15.27, 17 and 28, the values of the lower and upper bounds of the window 33 along the X and Y coordinates in the coordinate system of the information frame are entered. To the output of the information frame, the field bounded by the window 33,

- placed in the upper left corner of the screen (Fig. 26). Similarly, the output of the second, third and fourth fields is made.

Due to the implementation in the device of the selection of independent windows, which is part of a larger information frame, and output them to the specified screen locations with smaller information sizes, the information content of the proposed device is increased.
