Definitions

  • the invention relates to a display device for a display formed from individual display elements, wherein each display element is assigned an optical fiber with an associated hole in a display panel located in front of the display elements, with switching elements assigned to the individual optical fibers between the ends of the optical fibers and the associated holes in the display panel which can be brought into a non-display position covering the end of the assigned optical fiber or into a display position releasing the optical fiber by means of electromagnets.
  • Such a display device is known from AT 36-B-086E.
  • the optical fiber is held in a U-shaped bracket, in the side leg of which a pivotable cover is pivotally supported from the area of the bracket. In the non-display position, the cover closes the assigned hole in the display panel.
  • Such a structure of the individual display element requires a large amount of space also next to the bracket.
  • the display elements are not clearly decoupled from one another, which results in a deterioration in the switching ratio between light and dark of the display elements.
  • Other display devices of the type mentioned are known from DE-A-2 831 174 and DE-U-8 913 499.
  • a fiber optic illuminated sign system is known in which the ends of individual optical fibers are one Bundles are inserted directly into the holes in a display panel and form the display elements.
  • Such a display device is not suitable for changing displays.
  • each optical fiber is completed with a radiating body which protrudes into a compartment of a housing which is open towards the display panel and is held in an opening in the bottom of the compartment in that the switching element is designed as a flap with its axis of rotation is rotatably mounted in the area of the open side of the compartment and in the non-display position covers the open side of the compartment, that the radiating body is arranged outside the axis of rotation of the flap and serves laterally as a stop to limit the rotational movement of the flap to about 90 ° and in the display position is pivoted approximately halfway into the compartment, so that the end of the radiation body is released, and that a light collector is fixed in the associated bore of the display panel, which is designed as a section of a solid body made of glass or transparent plastic and in which at least facing the radiator front is polished.
  • the compartments of the housing enclose the radiation body except for the open side facing the display panel, so that the display elements are clearly decoupled.
  • the flap closes the assigned compartment and in the display position, the light collector defined in the display panel collects the light emitted by the released radiation body, so that a very high switching ratio between light and dark is achieved.
  • the compartments of the housing have an approximately square cross-section and that the flaps are rotatably mounted with their axes of rotation approximately diagonally to the compartments.
  • the cross section of the radiating bodies and the light collectors is round.
  • the display device can be constructed in such a way that the compartments of the housing with the radiation bodies defined therein and the associated light collectors of the display panel are arranged in a matrix in rows and columns.
  • both end faces of the light collectors are polished and close the display panel approximately flush with the respectively facing sides. It is then no longer necessary to pay attention to the position in which the light collector is inserted into the hole in the display panel.
  • the face of the light collector facing the radiation body is then, as required, always polished.
  • the setting of the display elements is solved according to one embodiment in such a way that the electromagnets in lines and Column-arranged flaps can be actuated one after the other in time and the flaps can thereby be brought into their display position, the rows being selectable cyclically and the columns being able to be actuated cyclically with setting pulses of a predetermined current direction during each row activation, while deleting the display elements, ie the setting of the non-display position , in that the electromagnets of the flaps arranged in rows and columns can be actuated one after the other in order to delete a display and the flaps can thereby be brought into their non-display position, the rows being cyclically selectable and the columns cyclically with reset impulses of an opposite one during each row activation Current direction can be controlled.
  • bistable behavior of the display elements is obtained in that the flaps are held in the display or non-display configuration by appropriate remanence of the associated electromagnets.
  • the structure of the display device according to the invention comprises a housing 10 for rotatably mounting flaps 15, as shown in FIG. 1.
  • This housing 10 consists essentially of a plate which has compartments 11 which are square in cross section to the display side and whose walls are integrally formed on the plate.
  • This housing 10 can also be composed of a plurality of sub-housings lined up in a row in order to obtain a matrix-shaped display device of sufficient size.
  • the compartments 11 are arranged in rows and columns.
  • a flap 15 is rotatably mounted with an axis of rotation 14 in such a way that this flap 15 covers the associated compartment 11 in the non-display position shown in FIG. 1.
  • a bore 12 is made in the bottom of the compartment 11 and receives a radiation body 30 attached to the end of an optical fiber 31.
  • the bore 12 is designed so that the radiating body 30 is held therein by a press fit and / or a snug fit and protrudes into the associated compartment 11.
  • the arrangement is such that the radiating body 30 lies outside the axis of rotation 14 of the flap 15, which preferably runs diagonally in the compartment 11 and is arranged in the region of the open side of the compartment 11.
  • Behind the compartment 11 is on the outside of the floor, i.e. attached to the plate, a pair of electromagnets 13 assigned to the flap 15, with which the two positions of the flap 15 are set. In the display position according to FIG. 1, however, the flap 15 can no longer rotate through 180 °.
  • the radiating body 30 forms a stop for the flap 15 laterally, so that it can only rotate by approximately 90 °, which releases the light emerging from the radiating body 30 and leads to a light collector 22 with end faces 23 and 24 which can be in front of the radiating body 30 is set in a display panel 20.
  • the distance between the display panel 20 is chosen so that the flaps 15 can adjust to the display position shown in FIG. 1.
  • the light collectors 22 are round in cross section and are designed as sections of a glass or a transparent plastic rod, at least the end faces 23 facing the radiating bodies 30 being polished in order to achieve a sufficient collector effect.
  • the end face 24 of the light collectors 22 on the visible side, ie the display side is also polished.
  • the end faces 23 and 24 of the light collectors 22 are approximately flush with the facing sides of the display panel 20.
  • the display panel 20 is provided with holes 21 which receive and hold the light collectors 22 in a snug and / or interference fit.
  • the electromagnets 13 are designed as pairs and have a remanence, so that the respectively set position of the flaps 15 is maintained until the other position is actuated.
  • Each compartment 11, ie each flap 15, is therefore assigned a pair of electromagnets. 1, each serve to adjust and maintain the display position according to FIG. 1, while when the other electromagnets 13 of the pairs are energized, the flaps 15 are brought into the non-display position according to FIG. 2 and held therein. In the non-display position, the flaps 15 close the associated compartments 11, wherein a side wall of the compartment 11 can serve as a stop.
  • the illuminated optical fiber 31 with the radiation body 30 is covered so that no light can reach the associated upstream light collector 22.
  • the end face 24 of the light collector 22 remains absolutely dark, so that a very high switching ratio between the display position and the non-display position of the flap 15 on the light collector 22 is achieved.
  • the display device can be constructed in matrix form M, the flaps 15 with the electromagnets 13 being arranged in rows z1 to zm and columns s1 to sn.
  • the wiring can take over a printed circuit board onto which the housing 10 with connections for the electromagnets 13 can be plugged on and soldered. Adjustment coils of the pairs of electromagnets 13 form an adjustment matrix, while reset coils of the pairs of electromagnets 13 form a reset matrix.
  • the control takes place via a processor PZ, which selects the lines z1 to zm one after the other via a line decoder DZ and controls a column decoder DS so that the columns s1 to sn are cyclically activated one after the other with each line control.
  • a processor PZ which selects the lines z1 to zm one after the other via a line decoder DZ and controls a column decoder DS so that the columns s1 to sn are cyclically activated one after the other with each line control.
  • Pulse control is sufficient because the switching devices of the display points behave in a bistable manner.
  • the reset matrix is controlled in the same way.
  • the electromagnets 13 of a pair can be decoupled in parallel with their setting coils and reset coils via opposite diodes, and thus the flaps 15 can be set and reset in a common matrix M with control pulses of different polarity.
  • the processor PZ can receive the information for the desired display in the parallel process via a control panel BF and a parallel control PS or via a computer R and a series control SS in the series process.
