(54) DEVICE FOR DISPLAYING INFORMATION

The invention relates to the field of automation and computer technology and can be used in the construction of graphic information display devices. Devices for displaying information are used that are used to output graphic information from computers and that contain a screen console connected to an electronic computer, a picture input unit, a control panel and an output block 1. The closest in technical essence to this invention is a device containing a block control connected to serially connected interrupt block, pulse generator, clock counter, symbol memory block, vector shaping unit, encoder, sc The coordinates are L and Y and the display unit 2. The disadvantages of the known devices are TDM, that it is impossible to obtain images of an unusual, previously unknown shape and colorings that could be used to obtain various textures and colors of fabrics, patterns on both, ornaments, coded images, unusual shapes, etc. The purpose of the invention is to expand the functional capabilities of the device. The goal is achieved by introducing a random number generator connected to a pulse generator, a character storage unit II to an encoder, a register connected to a clock counter, a delay unit connected to a pulse generator, and an interrupt trigger connected to b, choke. delay, register, random number generator, memory block, code, encoder, and counter by coordinates .Y and Y. The drawing shows the block diagram of the proposed device for displaying information. The device contains an impu generator, tic 1, a tick counter 2. symbol memory block 3, block of rights, 1 and 4, b, vector shaping lock 5, encoder 6, counter by coordinates X and У 7, block interrupt 8, display block 9, random number generator 10, interrupt trigger | 1 11, delay block 12, register 13, bus 14 for controlling random number generator 10, bus 15 for starting a pulse generator 1.

The pulse generator 1 is switched on by the imguls of the start of formation along the trigger line 15.

The random number generator 10 generates a random code, a part of the bits of which determines the type and orientation of the character forming the bounding lines, the part of the bit type and the oryoptation of the character that will be output at a given time within the bounding contour.

Interrupt trigger 11 switches from zero to one and vice versa with interrupt block 8.

According to the zero state of the interrupt trigger 11, a symbol limiting the contour is formed; by a single state, the symbol inside the limiting contour.

According to the zero state of the interrupt trigger 11, the input of the memory block of symbols 3 and the encoder 6 is received from the random number generator 10, the type codes and the orientation of the symbol forming the limiting circuit, the register code 13 is overwritten in the clock counter 2 and information is transmitted from the encoder 6 for bits (nx + 1) and (tu + 1) of the counter according to the coordinates yV and Y 7, where nx and Shu are the number of elements of the decomposition of the symbol mistrastra inside the bounding contour, respectively, horizontally and vertically.

Thus, for the symbol that bounds the contour, the raster resolution is equal to n and m y, and for c and m wave inside the contour a - 1 / n

and l / lTiy.

When forming the symbol bounding the contour, the control unit 4 com. Mutes the impulses from the generator impulses 1 to the clock counter 2, or to the vector forming unit 5.

In turn, the control unit 4 is excited by signals from the interrupt block 8, which are formed at the moment when the reproduction of the next vector of the symbol contour ends.

The signal of the end of the last vector (the last vector of the symbol's contour is marked in the memory block by sigol 3 by the sign of the end of the reproduction of the symbol) in the contour of the symbol is simultaneously the signal of the end of the reproduction of the symbol blocking the pulse generator 1.

At the end of the reproduction and the next vector, the clock counter 2 switches to c; i.e. its state and the information on the parameters of the next vector is read from the memory of symbols 3.

Thus, the clock counter 2 alternately reads from the memory block of symbols 3 the codes of all vectors relating to the contour of the symbol being played during this period.

The code of the part of the bits read from the memory block of signals 3 to the vectoring block 5 is interpreted as a control code.

the color of the vector (brightness, color tone, saturation), the code of the part of the bits - as the code of the direction of the vector, the code of the other bits - as the code of the length of the vector.

The encoder 6, using the direction code, generates counting pulses for the forward or reverse (reverse) counting of the counter along the coordinates X and Y 7. The number of these pulses is determined by the length of the vector.

As soon as the first vector of the symbol is formed, which limits the contour, the interrupt trigger 11, by the signal from the interrupt block 8, will go into one state.

The interrupt trigger 11 unit state records the clock counter code 2 into the register 13. the clock counter 2 returns to its initial state, the character memory 3 and the digitizer b are connected to the input of the random number generator 10 character codes and orientation inside the contour.

Fully molded symbol within an edge loop. The operation of the device during the formation of the symbol inside the bounding contour is performed by g as well as the symbol bounding the contour, as described above.

At the end of the formation of this symbol, the interrupt block 8 generates a signal on which, on a part of the bits of the random number generator 10, specifying the type and orientation of the symbol played back within the limiting loop, the random code of the previous symbol is replaced with the random code of the next played symbol; interrupt trigger 11 switches to the zero state; the pulse generator 1 is blocked, then it is started up through the delay block 12.

The full image playback procedure continues until then. until the symbol is fully formed, the constraints of Koirryp. Then the signal from the vectoring unit of the vector 5 according to the zero state of the interrupt trigger 11 changes the state of a part of the bits of the random number generator 10, specifying the type and orientation of the symbol reproducing the limiting circuit, will block the pulse generator 1. Because the zero state of the interrupt trigger II block delay block 12, then the start of the pulse generator 1 does not occur.

The generator of the pulses is triggered by the next pulse of the beginning of the formation of the formation, not 15 of the next image.

Pa random number generator 10 by control 14 can be used to signal the bits of the code for the character limiting the contour and / or the signal of the wave inside the contour to be formed not by random but by a given image, therefore a part or all of the generated image can be obtained operator, i.e. the operator can adjust the reproduced image accordingly in the desired direction.

Changing the orientation of characters is obtained as follows. Gifter 6, which is a combi-opio circuit. It forms for the counter at the coordinates X and Y 7 the COLLECTION of the counting pulses ± X, 0; ± Y, 0.
