Abstract

The display (10) comprising a number of basic display elements arranged according to a plotting representing an alphanumeric character, and it is linked to transcoding circuits (2, 3) that, after receiving data representing a digit, furnish a specific set of individual commands for various basic display elements, whereby this furnished set excites a certain number of basic elements according to a pattern specific to the digit.

Claims

1. Display for a value in a range of a first plurality of possible values of a digit, comprising a second plurality of display base elements independent one from the other to display any of said values by control of one of said first plurality of base elements groups whose respective positions form together a pattern specific to the considered value, wherein said respective positions of all the second plurality are arranged in a base pattern whose shape substantially represents an alphanumeric character.

2. Display according to claim 1, wherein one of the base element positions is located, in the base pattern, at a level specific to the considered base element.

3. Display according to claim 2, wherein said base element at a specific level is at a level either extreme or halfway up in the base pattern.

4. Display according to claim 2, wherein said base element of specific level is arranged to show a display state different relatively to the display states of the other base elements.

5. Display according to claim 1, wherein the base pattern substantially represents a letter.

6. Display according to claim 5, wherein the base pattern represents a letter among the group comprised by the letters d, E, I, L, O, V.

7. Display according to claim 1, wherein at least one of the base elements shows an elongated shape and at least another of the base elements shows a substantially circular shape.

8. Display according to claim 1, wherein the base pattern is bi-dimensional.

9. Display according to claim 8, wherein each specific pattern is bi-dimensional for the digits exceeding 2.

10. Display according to claim 1, wherein the base pattern is visible at rest.

11. Display assembly comprising several displays according to claim 1, in order to display a number.

12. Display assembly according to claim 11, comprising at least two displays arranged so that each displays a value among respectively at least two values and at least eleven values.

13. Display assembly according to claim 12, wherein both displays are arranged so that each displays a value among respectively three values and twelve values.

14. Display assembly according to claim 11, comprising four displays, whose base patterns represent respectively the letters L, O, V, E.

15. Display assembly according to claim 14, wherein the four displays show second pluralities of respectively two, nine, five and nine display base elements.

16. Control device of a display according to claim 1, wherein it comprises transcoding means arranged to, after having received data representing said digit, provide a specific corresponding set of individual controls for the various display base elements, the provided set belonging to a pool of a said first plurality of sets available for respectively the first plurality of the digit possible values.

17. Device according to claim 16, wherein the transcoding means comprise a transcoding table in a read only memory.

18. Device according to claim 16, wherein the transcoding means comprise a binary counter comprising a third plurality of binary stages each having a serial input for the counting and an output connecting them serially, a first said stage being provided to receive, through the counting serial input, a continuous stream of pulses of determined period, the plurality of outputs further being connected to inputs of a transcoding combinatorial logic circuit having outputs to provide feedback controls arranged to control a said third plurality of storage priority control parallel inputs, in respectively the stages, of respective bits representing a transcoded number.

19. Device according to claim 16, wherein the transcoding means are arranged so that any two adjoining sets, in an ordered sequence of eight first said individual controls set, for respectively the values 1 to 8, each have at least two different controls relatively to the adjoining set.

20. Device according to claim 16, wherein the transcoding means are arranged so that, in some of the control sets, the display controls of the respective values correspond to base elements positions arranged in said specific pattern substantially representing a conventional writing form of the considered value.

21. Device according to claim 16, wherein the transcoding means are arranged to provide, selectively, one among a said first plurality of nine individual controls sets, for respectively values in a said range from 1 to 9, each controls set including a number of controls equal to the value to be displayed.

22. Device according to claim 16, wherein the transcoding means are arranged to control an array of display control circuits arranged to invert the feed polarity of a said second plurality of dipoles, forming the display base elements and each providing a choice of two possible colors according to the polarity, and further arranged to inhibit on command the dipoles.

23. Assembly of control devices according to claim 16, comprising an assembly of said transcoding means for respectively the displays of an assembly comprising several displays in order to display a number.

24. Devices assembly according to claim 23, wherein, so that two said digits of same value are represented by two patterns substantially alike of two of the displays, the transcoding means are arranged so that both respective sets of individual controls are in harmony one with the other in order that both said respective groups are formed by base elements being at positions defining two patterns of substantially the same shape.

25. Devices assembly according to claim 23, wherein first and second of said transcoding means are coupled one to the other so that the first transcoding means control an increment of the second transcoding means when the first transcoding means reach a value representing a numbering base.

26. Devices assembly according to claim 25, wherein the first transcoding means are arranged to provide, selectively, one among a said first plurality of at least nine individual controls sets, for respectively values in a said range from 1 to 9, each controls set comprising a controls number equal to the value to be displayed.

27. Devices assembly according to claim 23, comprising a step motor arranged to, by the control of the transcoding means, drive a movable display track on which are distributed said display base elements patterns, cooperating with a pattern pointer.

28. Display system comprising a display according to claim 1, or a display assembly comprising several said displays in order to display a number, wherein said system comprises a control centre including control centre management means arranged to control, at the occurrence of events of predetermined type, display control means provided to control one said display (810, 910) comprising some said display base elements.

29. Display system according to claim 28, wherein each display base element is comprised of a pixels block and the display control means are arranged to display an image specific to each pixels block.

30. System according to claim 29, wherein the control centre management means are arranged to select an image in a library and to address it to a specific pixels block through the display control means.

31. System according to claim 30, wherein the library is designed to provide moving images data and the control centre management means are arranged to transmit, to the display control means, data packets including a sequence of said images.
