The invention relates to means of displaying visual information and can be used to control matrix indicators constructed on various physical bases.

The purpose of the invention is to improve the quality of the image by increasing the contrast.

The drawing shows a functional diagram of the device for displaying information.

The device contains a pulse generator 1, a counter 2, a decoder 3, a switch 4, units 5 sampling psh on X coordinate, liquid crystal matrix indicator 6, code converter 7, multiplexer 8, first character generator 9, second symbol generator 10, block 11 sampling tires on coordinate I , elements 12 and 13 coincidence, trigger 14, switching elements 15-18, control block 19

The device works as follows.

5 1 7. The generated code is fed through block 11 to selected vertical indicator buses,

 Upon completion of the alternate scanning of horizontal buses, the control unit 19 at the time determined by the signal from counter 2 and dependent on the size of the matrix 6 generates control signal sigIQ for switch 4 and multiplexer 8, which switch the scanning channel so that at the subsequent frame time scans the vertical tires of the 5 torus indicator, and the information signal is fed to selectable horizontal indicator tires. At the same time, the signal from the control unit 19 at the time of switching the scan from the horizontal

20 buses to vertical multiplexer provides the input code to the character generator 9. One and the same input code in the first and the second character generators

25 and the same sign at the output of the character generator However, in order to avoid the rotation of the image on the display panel by 90 °, the symbols in

- character generators are written with

Consistently connected blocks

. „.,. Ep of this. At the end of the alternate ska1 and 2 form code combinations,

incoming to the inputs of the decoder 3, control block 19, on the output code of the counter corresponding to the number of rows of the matrix, the coincidence element 12 triggers, the signal from which 35 grams goes to trigger 14, the trigger generates a control signal to the switching elements 15 and 16 of multiplexer 8, while these elements are closed, and elements 17 and 18 are blurred-40 pulses, the output of which is connected to the cabin. When the counter code is 2, the corresponding information input of the counter, the number of matrix columns, the stroke of which is connected to the information trigger by the element 13 signal by the decoder identical input, the sampling unit feeds the bus switching elements according to the Y coordinate, the output of which is first the control signal, which is connected to the horizontal busbars, switches the switching elements into a first-liquid matrix initial state. The decoder 3 generates scan signals, which are fed through the switch 4 and block 5 to the horizontal buses of the matrix indicator 6. In synchronization with the operation of the information input of the device, blocks 1-3, the sound channel of the scanning channel is formed, the information signal is generated to

The operation of all vertical busbars, the compressor 4 and the multiplexer 8, commutate the formation circuit of the scanning and information signals to their original state.
