Description

The invention relates to means of displaying information and is intended to create large placards, screens for collective use, sign-synthesizing elements and similar structures of a color image using reflected or transmitted light (passive or active display mode).

The aim of the invention is to expand the scope of the indicator

by increasing the number of informational gradations.

Figure 1 shows the indicator; figure 2 - electrodes; fig.Z - functional diagrams of the indicator.

The indicator includes a housing 1 with an information aperture 2, a base 3, a light source 4, dielectric pillars 5 and 6 forming a pair, electrodes made in the form of plates 7 and 8 and placed on stalls

as 5 and 6, first 9 and second 10 transparent flexible tapes, additional metal plates 11 and 12 mounted on racks 5 and 6 constituting a pair, U-shaped bracket 13, included in the first pair, U-shaped the bracket 14 entering the second pair, the flexible color filter 15, the first metallized section 16 of the belt 9 (10), the second metallized section 17 of the belt 9 (10).

Flexible metallized belts 9 and 10 are made with translucent areas, and on part (or all) of the surfaces of belts 9 and 10 are mounted flexible, diffusely scattering light colored filters 15, for example, from dyed thin (for example capromy) fabric , the dimensions of each light filter 15 are not less than the dimensions of the information aperture 2. Thus, the information interference in the form of glare from glass is eliminated, the cost is reduced, and the production of flexible tapes 9 and 10 is simplified,

Flexible belts 9 and 10 are placed one on top of the other cross-by-cross and are supported on two pairs of brackets 13 and 14. Each pair of brackets 13 and 14 has a slightly different height, which ensures the mutual displacement of the belts 9 and 10 vertically. The ends of each belt 9 and 0 are fixed at the upper edges of the uprights 5 and 6. Between each bracket 13 and the counter 5 opposite it (5) there is a cavity into which a part of the belt 9 (10) sags. The maximum depth of its sagging (in one of two possible extreme positions) is equal to the height of the uprights 5 and 6.

The transverse size of the cavity is chosen such that under the action of the potential difference between the sections 16 and 17 of the metallization of the tape 9 (10) and the plates 7 and 11, the sagging part of the tape 9 (10) is freely placed in the cavity. In the absence of the potential difference of the sagging, a part of the tape 9 (10) is fixed in the cavity due to the mechanical friction forces on the plates 7 and 1 1.

The upper and lower edges of any plates 7 and 11 have a comb shape, and the height of plates 7 and 11 is approximately equal to half the linear size of the information hole - 2 This solution allows, if necessary, increasing the height of the racks 5 (6)

and increase the number of plates 11 and 12. This ensures reliable switching of the tape 9 (10) from the previous plate 7 (11) to the next one, since when the voltage is applied between sections 16 and 17 of the metallization, the belts 9 (10) and one of plates 7 and P tape 9 (10) is spread, for example, over plate 7, simultaneously pressing against the protrusions of plate 11, which is currently under the potential of section 16 (17) of metallization of tape 9 (10) electrically isolated from adjacent plates 11 located on rack 5 (6).

As the potential is supplied to plate 11, the tape 9 (10) spreads along it, moving under the information opening 2 to the linear size of the light filter 15 (information opening). To display information in the active mode (used when the ambient light is lowered), the source 4 of light is placed in the space between the brackets. In order to reduce the loss of light, the light source 4 is located as close as possible to the light filters 3 of the tape 9 (10) and shines through the fully light-transparent section of one tape (for example, tape 9) to light filter 15 on another tape (for example, tape 10). It is possible to mix colors while simultaneously scanning through multicolored filters 15 of both belts 9 and 10.

The two opposing posts 5 and 6 are mounted on the base 3 of the housing 1 in the current-carrying spring contacts. Plates 7 and 1 are fixed on one side of the dielectric stand 5 (6). On the back side of this stand 5 (6) are the terminals of plates 7 and 11 and the current lead to section 16 (17) of the metallization of the flexible tape 9 o. The connection of the leads of plates 7 and 11 with the plates 7 and 11 is carried out by metallizing the through holes (Fig. 2, black dots).

Through the corresponding contact springs, the electric potential is applied to the plates 7 and 11 and the current supply to the metallization sections 16 (17) at the ends of the flexible tape 9 (10). The metallization sections 16 (17) on the tape 9 (10) are connected to the current leads through electrically conductive, for example, rubber, gaskets, which are fastened to the racks 5 and 6 with strips. Other strips

press and fix the tape 9 (10) on the uprights 5 and 6 so that its dielectric side touches the upper edges of the plates 7 and 8.,

The bending tape 9 (10) is thrown over the l3 (4) brackets installed on the base 3. The height of each bracket 13 (14) exceeds the height of the pillars 5 and 6 by the linear dimension of the information hole 10, equal to the filter 15, and the distance between the brackets 13 ( 14) equal to this size. The planes of the brackets 13 are parallel to the planes of the pillars 5 and 6. 5

Each end of the tape 9 (10) is metallized (on the one hand) in section 16 (17), the length of which exceeds

the light filters 15 are fixed on it, followed by the metallized section 17 of the tape 9 (10), which is fixed on the upper part of the plate. The latter, together with the electrode 12 insulated from it, constitutes the second group of electrodes (Fig. 3b). Under the tape 9 (10) between the brackets 13 is placed a source of 4 light. Above the tape 9 (10) there is an information opening 2 with a linear dimension of 1, thinned with a transparent polymeric film.

and 11 and section 16 of the metallization of the tape 9 (10) there is no potential difference.

The section 16 (17) of metallization with a current lead on racks 5 and 6. The rest of the tape 9 (10) is translucent. For example, the total tape length Bd (g, 1) is approximately equal to five linear dimensions of the information aperture 2, and its translucent part occupies 3/5 of the total length. On the translucent section of the ribbon 9 (10) multicolored light filters 15 made of thin nylon fabric are placed. The sides of the optical filters 15 are glued (welded) at separate points on the side edges of the tape.

If the light filters 15 are made in the form of a single strip with areas of different colors, it is also possible to fix them differently: gluing (welding) overlapping the ends of the light filter strip 15 to the translucent and metallized ends of the tape 9 (10). I

The diagrams (fig. 3) show metal plates 7, 8, 11 and 12; M - sections 16 and 17 of metallization on the belt 9 (10); P - translucent section of the tape 9 (10); F1, F2i etc. - light transparent sections of tape 9 (10), on which light filters 15 are fixed; M + F - section 16 (17) of metallization of the tape 9 (10), on which the background filters 15 are installed. The first group of electrodes (Fig. 3b) consists of metal plates 7 and 11. In the upper part of the plate 7 there is a fixed section 16 of flexible flax -., you 9. Between the brackets 13 is a translucent section of the tape, which hangs from the left bracket 13 to the right and

It is accepted by J that all areas of the metal 25 at the ends of the belts 9 and 10 are galvanically connected and are a common point. We remove the potential from the plates 12 and simultaneously feed it onto the plate 7. At the same time, on the plates 11 and 12 30, potentials are maintained equal to the potential of sections 16 and 17 of the metallization of the tape 9 (10). Under the action of electrostatic forces, half the length of the metallized section 16 of the tape 9 (10) rolls (spreads) onto the plate 7. At the same time, half of the metallized section 17 of the tape 9 (10) will go up from the plate 12. The translucent section of the tape 9 (10) will move to the left, and the light filter 15 will be inserted between the straps 13 and 14. Since the pasteins 7, 8, 11 and 12 are comb-shaped, the tape, which is rolled onto the plate 7, will also be pressed into the plastic. 7 parts (teeth) of plate 11. While it is under the potential of section 16 of the metallization of tape 9 (Yu), but as soon as the working voltage is applied to it and at the same time the potential is removed from plate 8, a new movement of tape 9 will follow ( 10) to the left, and light

the light filters 15 are fixed on it, followed by the metallized section 17 of the tape 9 (10), which is fixed on the top of the plate 8. The latter, together with the electrode 12 insulated from it, constitutes the second group of electrodes (Fig. 3b). Under the tape 9 (10) between the brackets 13 is placed a source of 4 light. Above the tape 9 (10) there is an information opening 2 with a linear dimension of 1, thinned with a transparent polymeric film.

It is accepted by J that all metallization sites at the ends of the belts 9 and 10 are galvanically connected and are a common point. We remove the potential from the plates 12 and simultaneously feed it onto the plate 7. At the same time, the potentials on the plates 11 and 12 are equal to the potential of the sections 16 and 17 of the metallization of the tape 9 (10).

increase their transverse size and fix (get stuck) in the cavities between brackets 13 (14) and racks 5 and 6

Thus, in the proposed indicator with two tapes, it is possible to indicate four independent colors and some combinations of these colors when the indicator is in active mode (through the light).

It is convenient to be able to choose (and vary) the background color of the indicator identical to the color of the casing of the whole structure. But dp of this it is necessary to use some number of light filters 15. Increasing the number of background filters allows organizing the construction of the indicator according to the diagrams (Fig, Sv, g). They differ, from the indicated scheme - ffci (fig.zb, fig,) by the presence of two additional plates 11 (12) on each rack 5 (6), a longer ribbon (approximately seven linear dimensions of the information aperture, bd 7) and two times longer metallized sections 16 and 17 of tape 9 (10). Background filters 15 are now fixed on the half of the metallized areas. Such a solution makes it possible to keep the filters 15 above the translucent part of the tape 9 (10) for their direct use for their intended purpose.

Increasing the height of brackets 13 and 14 relative to the height of racks 5 and 6 and adding the number of plates 11 and 12 on each rack 5 and 6, you can increase the number of actively displayed colors (familiarity, alphanumeric characters, etc.). The principle of operation of such multi-position devices is no different from this. Each of the plates 7, 8, 11 and 12 must be connected to the poles of the power source through the load and the key (not shown), and the sections 16 and 17 of the metallization of the tapes 9 (10) to one or the same common pole. In both groups of electrodes (for one tape), the number of de-energized 7, 11 and insulated 8 and 12 plates loaded under voltage is always equal, i.e. equal to the number of simultaneously closed and open keys. Plates 7 and 11, B and 12 of the opposing racks 5 and 6 work in pairs in antiphase. In comparison with the known indicator, the color gamut of the indicated

information, simplified technology display information in color on the tape, which expands the scope of the indicator.
