Description

ROTATIONAL DISPLAY EQUIPMENT

The invention is a rotational display equipment which can be well used for the complex display of multicoloured, moving, alpha-numeric and graphic infoπnation, cartoons, other animation, special effects activated with an external event at the same time, first of all for the purpose of calling people^'s attention

Furthermore it is suitable foi example for starting a program stoied as an effect of movement perception in a given place and at the same time foi activating foi example a sound-giving device, and for operating external units at a progiammed time and foi a piogiammed period, foi displaying the exact time, temperature, exchange rates, etc

Apart from this - equipped with an appropriate adapter unit - it is suitable foi example foi displaying and/or creating the JACKPOT value in amusement arcades, or for showing various sights in the case when no game is played

As it is known, theie aie several solutions and equipment foi displaying advertisements, different information, animated seπes of pictuies. moving images The light sources used for these can be cathode ray tube, neon, halogen lamps, liquid crystal, LED-s. etc.

In a wide range of illuminated infoπnation equipment that lepresent the known technical level the so-called dot-matrix solution is used where the picture to be displayed is put together from picture dots The advantage of these solutions is the quick operation, but their disadvantage is that a laige number of light sources of the same colour are needed for lighting each picture dot for a determined period, and its price is rather high. There aie also display boards that operate with halogen lamps, their disadvantage is that the displayed picture is dim, it operates slowly, the solution demands a lot of energy and is also expensive.

The solution described in the patent application called "Switching arrangement foi the operation control of illuminated infoπnation equipment" under the registration number' HU 196097 also lepiesents the technical level It is in connection with the prevention of the eπor that got into the illuminated paper working method data process (e.g tiansferπng from column to column) and with the transfer of multi-sided optional sample lo combinations in an optional direction, by providing the possibility of editing, controlling and coπecting while the progiain goes on This task is solved with a switching aπangement which has a data processing microprocessoi. a feeding unit, a controlling unit, a data store, controlling and altering devices and a data-saving periphery, and the data stoie has a RAM and ROM aiea as l i well as a character scieen store and a diagram screen stoie which aie connected to the controlling unit and to the output unit. The disadvantage of this known solution is that all the scheduling, the storing of the data and the diagram display on the displaying board is contiolled by the same microprocessoi which allows operation only at a low speed and it cannot 0 correct the mistake on the displaying boaid in less time than 20 msec Quick operation at an appropriate speed could only be achieved with a modem processoi that would be very expensive and so it would increase the production cost of the whole equipment so much that it would make it impossible to sell it

The operation of the rotational display equipment is described on the basis of the diagrams.

The performance program is programmed - e.g. by computer - into the program and data store unit ( IC) of the cential contiolling unit ( 1 ) through the programmable input-output line group ( 15) and through the input-output unit (IB), this program contains the series of the pictures to be displayed by the user. Practically the program and data store unit ( I C) has the following stores:

- ready-made cartoon,

- character generators with several types of shades and transparency,

- program needed for the operation of the CPU 1 ,

- performance which is equipped with secret protection, so the loaded program cannot be read. io - it can be written and read

In the picture memoiy unit ( 1 E) the CPU 1 data processing central unit ( 1 D I ) makes the data foi the pictures to be displayed , which can be the following

i i in the case of off-line display

- cartoons by picture elements (pictures squares),

- alpha-numeric infoπnation.

- in the case of movement along a circular arc. in the process of the picture of the whole text by units to be displayed that are bigger than a picture 0 element.

- in the case of radial movement each picture element must be stored separately in the case of on-line, real-time display (e.g. when displaying the time or other actual information, e.g. foreign exchange rate. JACKPOT prize) 5 - apart from the above the actual data (values) are also shown by off-line display put on each other at the same time.

In this way the data of eveiy picture to be displayed is stored m the picture memoiy unit ( I E), and the display is done from this so that the data stored in o the picture memoiy unit ( I E) are started to be supplied on the output (51 ) of the rotation perceiving unit (5), through the rotation perceiving input ( 14) of the central controlling unit ( 1 ), in at a pace determined and synchronised to rotate by the PLL circuit ( I F) The pictuie display is controlled by the CPU2 data processing central unit ( 1 D2), if it lecognises the secret piotection code, thiough the senal data output ( 13 ) of the paiallel-senes transformer ( 1 G) and the output of the information transfei unit (3) so that the data of the pictures to be displayed aie shown at the appropriate time on the rotating pictuie displaying unit (2) In this way the generation of the data and the display is done at the same time, timed by the logical timing unit ( 1 H)

io In the case that the picture memoiy unit that stoies the pictuie ( I E) is not static but dynamic memoiy, then peimanent updating is needed which is done with the updating countei ( I I )

The input unit (2A) of the l otating display unit (2) leceives the senal data i s fiom the output of the infoπnation tiansfei unit (3), and with the leading edge of the sign that appeals on its output it starts the fii st mono-stable multi- vibiatoi (2B 1 ) whose output sign's tiailei edge gives the point of time when it is necessary to take a sample of the output sign of the input unit (2Λ) to get a bit of the senal data 20

T he data input of the shift legistei (2C) is also connected to the output of the input unit (2A) and the output of the fust mono-stable multi-vibratoi (2B 1 ) is connected to the clock signal input of the shift iegister (2C), and so the sample taking is iealised at the appropπate time when a data bit gets in the 5 shift registei (2C)

The timing of the second mono-stable multi-vibiatoi (2B2) is set so that as long as data aie arriving continuously on the output of the input unit (2 A), the output signal of the second mono-stable multi-vibratoi (2B2) is io maintained continuously If the second mono-stable multi-vibratoi (2B2) does not receive any more prolonging signals, then its output signal is emitted which writes all the data bit that is in the shift register (2C) into the general buffer (2D) at the same time at once Then the third mono-stable multi-vibrator (2B3) enables the general buffer's (2D) n-number. favourable eight dπvei 's parallel output, and the practically used n-number LED FI, 5 Fn light source displays the picture elements of a radial column (pixel) on the lotating picture displaying unit (2). It is practical to set the delay time of the third mono-stable multi-vibrator (2B3) so that it is a square signal with a 1 I packing fi action (In this way it can be achieved that the picture elements aie separated from each othei in the displayed picture ) io

In the case that you intend to display not separate picture elements, then the thud mono-stable multi-vibratoi (2B3) can be quitted and in this case the display will be brighter

i i The outputs of the general buffei (2D) noimally have high cuπency ( Λ light souice block that consists of eight LED-s could be dπven by a single geneial buffei (2D) ) If this LED is not sufficient foi the control of F I , Fn light souices. then the output cuπent can be doubled by the paiallel connection of two geneial buffets (2D) In the an flow lesulted by the lotation the LfcD-s o can be loaded moie than in other cases

The independent in/outputs of the central contiolling unit ( 1 ) aie to influence the progiam of the CPU l data piocessing central unit ( 1 D 1 ). so

5 - with the manual operation of the parametering ( I I ) it is possible to do practical program branches and/or to set and control data. e.g. if someone leaves, it perceives the movement, it displays what name-day it is that day, it plays music that suits the situation, it chirps, etc and then it tells you the day's offer, o - with the event perceiving input ( 12) it is possible to do the same electronically as with the manual operation of the parametering input ( 1 1 ), - with the help of the programmable in/output line group ( 15) an external computer can be connected to the equipment and through this it is possible to load the performance given by the user,

- with the external equipment controlling output ( 16) it is possible to i control, start and stop the equipment and devices (e g tape-recorder, twittei, etc.) that are connected to the equipment

In the case of a favourable construction of the rotational display equipment the rotating unit (6) is practically a special electric motor which is mounted o directly on the shaft (61 ) and iotates the piopellei on the iotating pictuie displaying unit (2) so that the eneigy transferring unit (4) and the information transfening unit (3) are also mounted directly on the shaft (61 ) In this case. if the electric motor is loaded with a two-sided propellei. it rotates at just the right number of revolutions pei minute Of course it is possible to rotate in other ways as well, e.g. with a turbine, watei, or an, and in this case the power supply unit (7) is not needed

In the case of a practical constiuction of the eneigy transfei unit (4) the transfei of the 12 V direct voltage leceived on the fii st output (71 ) of the o powei supply unit (7) is done to the iotating pictuie displaying unit (2) with slip πngs which are stabilised by a UT = 5 V stabilisei Greatei capacity can be transfeπed by a rotating transformei or a motor with a winded aπnatuie

Practically the information transfer unit (3) is a rotating condensei, so the i input unit (2A) is a high frequency conpratoi, but a slip ring can also be used for this puipose The rotation perceiving unit is a revolution number counter that operates with an optical infra-red tiansmitter-receivei circuit and the PLL circuit ( I F) connected to it gives the nu bei of the columns Practically the rotation perceiver (5) is situated on the shaft (61 ) In connection with the o cential contiolling unit ( 1 ) it can be said - apart from the above - that where the picture parts meet (beginning-end) there is a shift of one picture element which bieaks the pictures oi lnscπptions when displayed, so to prevent this it has a pictuie shift compensation which is practically realised with a computer

The pιopelleι(s) is (aie) situated on the iotating pictuie displaying unit (2) and contiolling electronics aie needed for its (then ) operation as it can be seen in figuie No 4 in connection with the favouiable construction example This solution is favourable, because the LED-s are positioned in a "V"-shape, along the diameteis of concentric circles, along two ciossing diagonals, the io iotation is much oie balanced because of the symmetiic placement on the two sides and so an appioximately continuous pictuie can be cieated fiee fiom flashing, and also the speed of the iotating pictuie displaying unit (2) need to be only half of the pictuie updating speed of the picture pei LED-s (By pictuie updating speed we mean how many times a complete pictuie is i s displayed by the used light sources )

With the appiopnate contiol of the led and green LED-s yellow coloui can also be pi ogiammed what is moie. by modulating the time flashing, seveial shades can be cieated between ted and gieen 0

I he LED-s with cases of the same coloui aie moie favouiable than the multi- colouied ones and they aie bπghtei Anothei advantage is that blue and its shades can be cieated lelatively cheaply with LED-s positioned in thiee lines while in the case of tiaditional point-matnx display this is only possible with 5 an extremely high number of LED-s and very expensively

If requned piopellei of several sides can also be used In this case the central contiolling unit ( I ) divides a picture to be displayed into as many parts as many sides theie aie The piopellei can be segment shaped, wave shaped, etc instead of a plane In the case of a large, several meteis tall equipment that can be put on a ioof, instead of LED-s any other light sources can be used, e.g with cathode ray tube, neon tube, etc In this case the cential controlling unit ( 1 ) is put on the rotating display unit (2) and the information transfer unit (3) has a programmable in/output gioup

The lotational display equipment achieved its objectives and its advantages are the following

- with a small number of light souices it displays a multi-coloured, complex pictuie, generated by an external event, in a combined, well visible, spectacular way. - simple, lehable construction,

- quick operation.

- economic production
