Quasi-analog display device

The invention relates to a quasi-analog display device according to the preamble of claim 1 or 9 ·

Such a display device is known from US Pat. No. 4,077,032. The display is carried out by group-wise control of spoke-shaped flat display elements which are incremented in accordance with changes in the measured values and which give the impression of pointers moving relative to a fixed scale. Here, φ can be a linear or a non-linear, e.g. B. act angular or circular scale; around the linear scale of a technical measuring device with parallel displacement pointer movement or around a circular clock face with concentric twisting movement of the pointer. The spoke-shaped flat display elements for electro-optical pointer display are electrically controllable optical components or component groups, for example in the form of electroluminescent diodes, electrochromic displays or, preferably, in the form of liquid crystal cells between a transparent front electrode and a rear counter electrode. To display pointers of different geometry for different physical quantities or units, in the case of a time display in particular for the quasi-continuous seconds, minutes and hours

show and, if necessary, for additional information, everyone orders from the generic display device Spoke area from a radial and azimuthal grouping partially different flat display elements; each of which can be individually controlled via its front electrode, with the entirety of all counter electrodes is interconnected to a single, common connection pole. Via a control circuit the individual front electrode connection poles are selected in accordance with the pointer geometries and positions to be displayed at the moment in time-division multiplex operation, that is, one after the other in rapid change, with the azimuthal display advancement of the individual pointer displays is effected via shift registers.

A disadvantage of this previously known quasi-analog display device is in particular the extremely large manufacturing effort for the design of the flat display area including circuitry effort for their control for the pointer display. The large number of each Flat display elements to be controlled individually In particular, such a large number of connecting poles to be led out individually that these and their cable runs to the assigned front electrodes, only accommodate with very large display devices let, for example, but practically not with display devices in the size of wristwatch dials.

It is a wristwatch with generic quasi-analog Display device on the market (Texas Instruments), in which the different pointers for the hour land for the minute display in the former case two radially short, azimuthally narrow and angularly opposite one another offset display segments are activated, while

rend the minute hand as a single, on the other hand long; and wider, spoke-shaped display segment in. Appearance occurs. The continuous seconds display takes place with a mark running along the outer periphery of the dial. However, this time display does not prove to be very meaningful, since the split hour hand in the case of the volatile Reading the time irritates; and there also one The second mark position is more difficult to perceive than a spoke-shaped pointer display.

From DE-OS 19 37 868 timing devices with quasi-analog Displays known for the continuous hour, minute and second displays on either different Radii concentric to each other revolving points or rotating spokes (with flashing second spoke to distinguish it from the identically designed minute memory); where in the latter If the hour spokes are not used for the other hand representations, but separately and only in the Half-hour intervals are formed, which causes irritating hour hand jumps, apart from the irritation, which assumes that two identical pointers are shown, which are only flashing from each other differentiate.

From DE-OS 28 03 899 is a generic display device known for a clock in which the number of display elements to be connected to assigned display elements via its own cable runs Connection poles by time-division multiplexing also of the counter-electrodes - that is, by means of voltage-division multiplexing the flat display elements - is reduced. For this purpose, the flat display area is subdivided into a number of azimuthally adjacent circular sections, each of which has an equal number of individual

r.peichen is assigned. The circular cutouts are rad i. For the representation of the minute hand, the individual spokes extending over both ring arcs are used one after the other activated, for the representation of the hour hand, on the other hand, only the one that extends over the inner ring arc Part of the respective single spoke. If the time display shows the minute hand and hour hand the same ■ Assuming an angular position, i.e. overlapping one another, provision is made for the hour hand to move in both azimuthal directions widening by additionally adding the part that is allotted to the inner ring arc of the azimuthally adjacent on both sides Single spokes is optically activated. However, this time display is also not very obvious, since the then The very wide representation of the hour hand makes it difficult to read and, in particular, its abruptly changing width is irritating. In addition, for practical purposes, there is no continuous seconds display with the arrangement shown is not feasible.

From DE-OS 28 34 387 a generic display device is known, in which also the flat display area in circular cutouts of two concentric to each other lying arches is divided. As many individual spokes are assigned to each circular section as different discrete pointer display positions can occur, again with the radially inner spoke part the hour hand and the entire length of the spoke

the front electrodes as well as the counter electrodes, in groups of meandering series connection of the single spoke-shaped flat display elements is a comparatively only little effort is required for the switching of the three pointer representations. However, points also here the pointer geometry, especially because of the Hour hand to the minute hand lengthening second hand, not yet the desirable meaningfulness, c3ie especially for the quasi-analog time display anr.untre-Ίο ben is.

The mentioned front electrocene group assignment to circular ring section counter electrodes with meandering lines between the front electrodes of the individual groups pen with time-division control of the front and counter electrodes is from DE-OS 24o3 172 for an accumulative Bow display previously known, which does not correspond to the conventional time display and therefore for the usual Time display, as well as for many technical analog displays, cannot be used because the arc display opposes the angularly offset single pointer display.

Accordingly, the object of the invention is to provide display devices of the generic type to the effect that a more obvious, distinguishable pointer representation for the different ones to be displayed Sizes, especially in the conventional time presentation, results; However, it must be ensured that the for this representation required number of connection poles even in the narrow display area of about wristwatch dials realizable and their control nevertheless with a comparatively simple control circuit using manageable voltage curves for the

BATH

Voltage multiplex operation of the display elements possible is.

According to the invention, this object is essentially the case for the implementation of simple standard pointer geometry solved in that the quasi-analog display device according to the preamble of claim 1 according to its characterizing Part is formed.

This solution is based in particular on the knowledge that it is often sufficient for the requirements of practice, especially with the quasi-analog time indication, to ensure that the visual superimposition of a second hand does not cause irritation with regard to the minute and / or hour hand presentation leads. When subdividing the spoke area, the voltage multiplex display element control known as such (see above) is therefore used, when the flat display area is subdivided into circular ring sections, which in turn are divided into circular arcs, with meandering element series connection across the individual spoke areas; As explained at the beginning, the "circular ring" or the "ring arcs" need not be geometric shapes with a finite radius of curvature. The meandering line routing for the series connection of the front electrodes not only in a circular ring section to the next, in each case reversing azimuthal direction with respect to the adjacent position of the individual spokes, but in particular also without a section-wise connection to certain individual spokes per spoke group, enables an upward-downward counting technique that is easy to use in terms of function quick access to the individual spokes with comparatively little control effort.

This group-wise interconnection of the individual spokes net with it the particularly easy to set up and function-testable time-division multiplex control of both the front and also of the counter-electrodes according to claim 2. It is based on the reversal of the spoke counting direction as it progresses, which is known as such from one circular section to the next; but now again a very considerable additional Effort is reduced by initially only controlling one of the individual spokes per cutout per spoke group becomes opposite to each other after the first reversal of the counting direction the neighboring of the previously skipped single spokes of the individual spoke groups of this section; and due to the meandering series connection, the previous single spokes in the first-mentioned section of the circle corresponding single spokes in the next-adjacent circular ring section with the azimuthal advancement direction retained in this respect as in the previously recorded circular section; etc., until all single spokes per spoke group and over all circular segments in the counting direction change after each circular segment pass, but maintaining the azimuthal Advancing direction are detected, so that this control sequence can start all over again.

A simple circuit implementation of this control is given according to claim 3, wherein per pointer representation and per flat display element electrode connection one on a counting basis - preferably as a ring counter - working incrementing device or register circuit is provided which, in accordance with the meander wiring of the individual spokes used for the pointer geometries to be displayed, partially are queried in opposite counting directions. Either directly from the assigned counting positions, or derived from the counting pulse control at the transition from one single spoke to the next per spoke group, from the spoke indexing devices the forwarding of the counter-electrode register

circuits obtainable, so that malfunctions due to Synchronization problems with regard to the time division multiplex control single-spoke front electrodes and geometrically assigned circular section counter-electrodes are not are to be feared.

The implementation of the invention is particularly simple Display device "when the spoke groups according to claim 4 and the single-spoke control according to claim 8 are formed. This allows a clearly narrow pointer display for the continuous display of the seconds Achieve per spoke group without great effort on individual flat display elements, with particularly little effort for the multiplex control. The slight angular Offset between the second hand and the hour or Minute hand positions practically only occurs when the pointer angle position is the same - but even then it does not interfere Appearance.

The further developments according to claims 5 to 7 promote the obvious or high-contrast pointer display without doing so Increased circuit complexity or problems with regard to what is available in addition to the analog scale. Space for the individual electrode connection poles occur.

In a manner known per se, it can also be used in the case of the invention Display device a part of a pointer, in particular the one located radially on the outside of the outer ring arc Part of the second hand spokes, can be used to provide additional information, such as entered via a Alarm time or calendar information, opposite corresponding Display marks along the analog scale.

The modified solution of the display device according to claim for the general implementation case or according to the claims 1o or 11 for simplified versions that meet the required

can already be sufficient in practice, is characterized by a high degree of freedom of design with regard to the display of the pointer with exact angular correspondence of the individual pointer representations from; for which a greater effort with regard to the electrode cable runs leading to individual electrode connection poles and accordingly also a. greater control effort is accepted.

Despite the large number of individual spokes per spoke group just the paired combination of single spokes assigned to one another on both sides of the central in the Group-located (narrow) single spoke the control circuit according to claim 12, so their expense is not in the same range grows as the number of individual spokes per spoke group. Reduced in the case of only three individual spokes per spoke group the effort for the counter electrode register circuits to simple bistable flip-flops, since the two sides The individual spokes located on the pointer axis of symmetry are interconnected to form the envelope to be controlled as a single single spoke are.

Gem.den also in this case of a symmetrical axis of symmetry spokes Group claims 9 ££ applies again that can be drawn for the Flachdisplayeleaente to any controllable in time and voltage multiplexing electro-optical devices, and that the scale annulus Krümmurigsradius need not be finite, and therefore a Realization mi "c is in any case partially parallel to each other aligned spoke groups within the scope of the invention.

In particular according to claim 13, the solution according to claim 9 ff opens up the possibility of revealing pointer geometry, for example for the design of curved pointer shapes for style clocks. The central pair of spokes (or the central single spoke) de spoke group can also be used in the representation of the minute and hour hands be controlled; But it can also be more useful _f here a? narrow ₃ non-disturbing gap to lasst-iij

1 shows, in a schematic diagram, one of a large number of spoke areas compared to an analog scale 1o1 1o2 composite flat display area 1o3. Its outer periphery 1o4 corresponds to the geometry of the analog scale 1o1, and the individual spoke areas 1o2 are after Oriented according to the pointer positions in relation to the analog scale 1o1. There are so many spoke areas 1o2 formed side by side, like different discrete pointer display positions in this quasi-analog display device the analog scale 1o1 should be able to occur. In the example shown, it is around the circular analog scale 1o1 in the form of a clock face 1o5, for example for wristwatches; and at 60 minute or second hand positions in the train To be able to display a "pointer" cycle are 60 such Spoke areas 1o2 azimuthally adjacent to one another uniformly distributed on a radially wide circular ring.

Each spoke area is 1o2 for pointer-shaped display occupied by flat display elements 1o6 of at least partially different widths and / or lengths, which can be optically activated by electrical control. It is, for example, according to the requirements the spoke geometry enclosed liquid crystals between a transparent front electrode 1o7 and one of the Viewing direction of the analog scale 1o1 remote, so rear counter electrode 1o8 (see. Fig. 2). But also other materials that can be optically activated by electrical control can be used to form the individual flat display elements 1o6 can be used, whereby the electrode output

3obildung is then modified in adaptation to this. To the Electrical control from a control circuit I4o (see FIG. 5) are the electrodes 1o7 / io8 via cable runs 1o5, 113 (see FIG. 2) with connection poles 11o, 111

... 13

connected, which in a remote edge or corner area outside the analog scale 1o1 on the carrier material for the Flat display area 1o3 are formed.

To simplify the overview, all flat display elements 1o6 are shown one below the other in the same way, although always only some of them are optically activated according to the current pointer position (cf. are visible. The front electrode line runs 1o9 are, invisible to the viewer, located radially outside the analog scale 1o1, or, to save space, _j below it.

For one with comparatively little effort, and in particular little space required for the front electrode cable runs 1o9, realizable, obvious representation of different pointers in the quasi-analog display opposite of the analog scale 1o1 is the flat display area 1o3 in η azimuthally adjacent circular ring sections Ni divided, in the example shown with i = 1o. Each of these annulus sections Ni is uniform in m spoke areas 1o2 subdivided in the form of spoke groups Mi, in the illustrated example with i = 6. Each Spoke group Mi consists of ρ - at least partly geometrically different from one another - through flat display elements 1o6 formed single spokes Pi, in the illustrated Example case with i = 2 from an azimuthally wide single spoke Pb and one azimuthally closely adjacent to it narrow single spoke Ps. Each single one of the single spokes Pi of a circular ring section Ni is with each one and only one single spoke Pi of each of the further circle ring cutouts Ni by means of the front electrode cable runs 1o9 connected in series, so that for the

... 14

Total of all flat display elements 1o6 as many front electrode connection poles 11o are to be provided as individual spokes Pi are provided per circular ring section Ni, in example case shown thus · m χ ρ «* 12 front electrode connection poles 11o. This is made possible by a meandering routing of the front electrode cable runs 1o9 Alternating from circular ring section Ni to circular ring section Ni + 1 In an arc shape on the inner periphery 114 and along the outer periphery 1o4 of the circular flat display area 1o3; namely such that the front electrode 1o7 of the first single spoke P1 of the first spoke group M1 of the first circular segment N1 with that of the last single spoke Pp of the last spoke group Mm of the next following circular ring section N2 as well as over this with the front electrode 1o7 of the first single spoke P1 of the first spoke group M1 of the next circular ring section N3, etc. also for all other single spokes Pi of the circular ring cutouts Ni is connected. So is for each individual spoke Pi a series circuit with the individual spokes located in the same direction in azimuthal order Pi of the next but one circular ring sections Ni + 2 and those in opposite directions in azimuthal order Individual spokes Pp + 1-i of the next adjacent one Circular ring sections Ni + 1 given without crossing meander. ·

As a result, there is _f with regard to the individual spoke groups Mi, an interconnection of the individual spokes Pi in opposite directions for each adjacent circular ring sections Ni + 1 and an interconnection in the same direction with regard to the individual spokes Pi of the next but one circular ring sections Ni + 2. For the illustrated preferred example of the grouping of a wide and a narrow single spoke Pb, Ps per spoke group Mi are therefore each front

electrode connection pole 11o from one circular ring section Ni to the next via peripherally internal or peripheral external cable runs 1o9 always alternating a narrow and a wide single spoke Ps-Pb-Ps -... in series switched, with opposite positional orientation in the individual circular ring sections Ni, thus progressing once clockwise and once counterclockwise, like shown in Fig.1, whereupon here to supplement the Aufbautmd Circuit description is expressly referred to,

As shown in Fig. 2, where to simplify the orientation in relation to the representation of FIG. 1, some marks the analog scale 1o1 are entered, each circular ring section Ni of the flat display area 1o3 is not only (see Fig. 1) azimuthally divided into m spoke groups Mi, but also radially divided into q ring arcs Qi, in the illustrated preferred example case with q = 2 in a radially wide, centrally located inner ring arc Qz and a this radially adjoining, radially shorter, outer ring arc Qa per circular ring section Ni. For the The area of each ring arc Qi are the counter-electrodes assigned to the individual flat display elements 1o6 (see FIG. 1) 108 summarized and via counter-electrode cable runs 113 led to counter-electrode connection poles 111; wherein, according to the simplified representation in FIG. 2, each Annular arc Qi a common, correspondingly larger-surface counter-electrode 1o8 can be provided which extends azimuthally and radially over the corresponding part of the flat display area 1o3 (see FIG. 1). the

J ₀ counter-electrode connection poles 111 are again shifted peripherally inwards or outwards from the flat display display area 1o3 in order not to be visually disruptive. The following applies to the sector-shaped geometry of the lateral edges of the individual ring arcs Qi that these

16

in the current implementation case, according to the position and geometry of the individual individual spokes Pi (FIG. 1), it is to be selected in accordance with the geometry of the analog scale 1o1 and the pointer orientation related to it; In particular, the ^H ring arcs ¹¹ Qi do not have to have a uniform or not a finite radius of curvature.

The electrically controllable material for optical activation the individual flat display elements 1o6 is to be selected in such a way that it can be controlled in multiplex mode; i.e., it has a defined response threshold voltage, so that the individual spoke-shaped flat display element 1o6 for pointer formation only then and only there visually appears within the flat display area 1o3, if and where the potential difference between the counterelectrode 1o8 of the controlled ring arc Qi of a circular ring section Ni and its individual spoke-shaped front electrode 1o7 the response threshold voltage of the flat display element Exceeds 1o6. So if at the moment only ring arcs Qi of a single circular ring section Ni are used optical activation of flat display elements 1o6 are controlled via their counter-electrode connection poles 111, and at the same time (at least) one of the front electrode connection poles 11o, then only this flat display element 1o6 is optically addressed in the affected one Annular section Ni, although due to the series connection also front electrodes 1o7 of other flat display elements 1o6 are detected by the same front electrode connection pole 11o - but which are not controlled via the ring arcs Qi Circular ring section Ni lie; see Fig. 5.

More due pointer display with the quasi-analog display it may be useful, contrary to what is shown in the principle illustration according to Fig. 1 / Fig. 2 to provide an electrode border according to FIG. Everyone is here wide single spoke Pb into a radially central inner Pbz and a radially outward adjoining it outer broad individual ^ peiche Pba subdivided, with arrow-shaped tapering of each outer end and with an arrow-shaped tongue-and-groove transition 115 between each other, which is electrically bridged by means of a radial conductor 116. In addition, the narrow one extends Single spoke Ps up to the approach of the outer taper of the outer part of the wide single spoke Pba. To increase of the contrast is preferably also in the case of the counter electrodes 1o8 (shown in dashed lines in FIG. 3) Corresponding border formed with tongue and groove transition 115 and outer taper 117, with azimuthal subdivision in corresponding segment-shaped counter-electrodes 1o8a / 1o8z for azimuthal coverage only one each Spoke group Mi; the counter electrodes 1o8 each of an arc Qi are connected to one another by azimuthal conductors 118a and 118z, respectively electrically connected via the counter-electrode cable runs 113 are connected to the counter electrode connection terminals 111.

A pointer geometry according to Fig. 3 in connection with the flat display area structure according to Fig. 1 / Fig. 2 results in the pointer time display shown in Fig. B. "25 seconds after three o'clock" j where the hour hand 119 consists of the 'central-inner part of a wide single spoke Pbz (see. Fig. 3), and the minute hand 12o additionally from the arrow-shaped but without significant angular expansion radially-außenl ± constricting T _e il wide single spoke Pba.

This is visible due to the not radially oriented but parallel longitudinal side edges 112 of this radially outer side Part of the "wide individual spokes Pba ensures that the minute hand 12o overall is not much more voluminous, more massive Looks like the hour hand 119 “what the error-free reading of the quasi-analog time display promotes. ,

It does not matter that (as can be seen from Fig. 3) at In this minute hand configuration, the second hand 121 is not uniformly parallel over its entire length clings to the adjacent side edge of the minute hand 12o because, as can be seen from FIG. 1, the second hand 121 in the form of the narrow single spoke Ps already has a slight azimuthal offset with respect to the minute hand 12o has the same information display position. A brief interruption of the second hand is also annoying 121 in the area of the transition 115 between inner and outer ring arc Qz / Qa not because the second hand 121 advances rapidly.

In spite of the enlarged pointer presentations according to the invention in the interest of obvious Expenditure on targeted, separately controllable individual flat display elements according to the present invention results there is the possibility of a comparatively inexpensive and functionally simple multiplex control.

In the same way, the opposite electrode connection poles 111i via a counter-electrode gate circuit 128 alternating with binary counter-electrode step oscillations SQ1, SQ2 (see FIG. 6) from a counter-electrode step vibration generator 129 controlled, with the circular ring opening increment via a counter-electrode switching device

The selection of front and opposite irode connection poles 11 oi, 1111 and application of step vibrations SPi, SQi takes place in such a way that only those individual spokes Pi - in quick succession to create a quasi-stationary optical impression - with the necessary potential difference be controlled so that the optical activation, ie a pointer display, takes place; where the Pointer length and the radial pointer positioning via the control of the ring arcs Qi in the selected circular ring section Ni is intended.

According to the meandering and opposing directions explained at the beginning The series connection of the front electrodes 1o7 then always results in a further connection from a section of a circular ring Ni to the nearest neighbor Ni + 1, if a type of spoke group single spokes Fi is traversed per annulus Ni in an azimuthal direction and on the neighboring Type of single spokes Pi in the same circular ring section Ni, reversing the azimuthal advance direction will.

For the selective optical activation of the time-division multiplexed flat display elements 1o6 with pronounced Response threshold characteristic is sufficient for the described function of the control circuit 14ο if the stage generator 143 on the one hand supplies two trinary step oscillations SP1, SP2, which are identical to one another but around are phase-shifted by a quarter period with respect to one another, while there are even two simple ones for the counter-electrode control binary step oscillations SQ1, SQ2 are sufficient, the - with regard to the mutual offset of the trinary step vibrations SPi in opposite directions - are out of phase by a quarter of a period.

As also shown in FIG. 6, a square-wave alternating voltage arises between the two first step oscillations SP1-SQ1 with the amplitude U / 2, which is not sufficient to activate flat display elements 1o6 (ü'ig. 1), if their response threshold voltage is between U / 2 and U. In contrast, the potential difference results in between to the two second step oscillations SP2-8Q2 an alternating step voltage which is asymmetrical with respect to the time course with the amplitude U, which is consequently sufficient to optically activate the flat display elements 1o6.

Those narrow single spokes Ps, their U-shaped Cover made of the wide individual spokes Pb adjacent on both sides and the frame line 151 connecting them Outer periphery 1o4 is open, are between the peripherally adjacent radially outer arc lines 153a via radially extending outer spoke lines 154a, and the narrow individual spokes Ps with to the inner periphery 114 opened U-shaped envelope between the adjacent centrally-inner arc lines 153z via central spoke lines extending radially inward 154z, connected in parallel via an external or a central pole connection line 155a or 155z (as shown in detail in Fig. 9), because (especially when the two central individual spokes Pi are drawn together to the central narrow single spoke Ps) here no U-opening for the passage of further connecting lines into the interior of the spoke group Wed more is required. This results in a need for two front electrode connection poles Ho for the outer ones or central internal lines 151/153/154/155 (a or z) for the electrical control of the spoke-shaped Flat display element front electrodes 1o7 (in Fig. 9 fully above the “counter-electrodes I08 indicated by dashed lines”).

For the flat display element configuration According to Fig. 9, a time display according to Fig. 10 results. Even if in the presentation of the hour and minute hands 119 »12o to simplify the circuit a control of the centrally located narrow single spoke Ps is dispensed with, arises due to the large-area geometric figure on both sides of this narrow, recessed central longitudinal axis is a closed, visually easily perceptible pointer impression with clear, sensible differences between the hour and the minute display. The second hand 121 is now not more angularly offset compared to the formation of the hour and minute hands 119/120 (as in the case of Fig. 4), but coincides geometrically exactly with matching display devices, so that any reading difficulty in this regard is now switched off.

For the hour hand display, the step vibration pairing SP1-SQ4 leads to activation of the flat display element, on the other hand the pairing SP2-SQ1 does not.

With the two trinary and four M-nary step oscillations SPi, SQi shown in FIG. 6, however, the pointer display can also be implemented in a two-step multiplex mode in a manner known per se, with only the second hand 121 and the in one step second step both the hour hand and the minute hand 119, 12o are shown. The combinatorial circuit complexity within the gate circuits 125, 128 is then somewhat greater, because a distinction must be made on a case-by-case basis as to whether hour and minute hands 119, 12o are to be displayed momentarily in the same circular ring section Ni or in different circular ring sections Ni, Ni ¹ . When using the step vibrations SPi, SQi entered in FIG. 6 and with the stipulation that the front electrode 1o7 of a flat display element 1o6 to be activated is to lead the trinary step vibration SP1, through the corresponding gate function of the gate circuits 125, 128, which are shown in the table according to FIG.

In the tabular compilation according to FIG. 12, the control ratios are entered above for the case that the hour hand 119 is currently to be displayed in the same circular ring section Ni as the minute hand 12o. Then all counter-electrode connection poles 111 of those ring arcs Qi ¹ , over which no pointer display is to take place, receive the voltage curve SQ1 from the step vibration generator, which with none of the front electrode step vibrations SPi results in the necessary potential difference for electro-optical activation of flat display elements 1o6. In the case of one spoke group M1 from the step vibration generator 126, the front electrode connection poles 11o are controlled with SP1 and the other spoke group M2iSP2. If the hour hand 119 is to lie in the first spoke group M1, the outer associated ring arc Qia is to be subjected to a step oscillation SQi selected in such a way that no electro-optical activation takes place, in the case of the front electrode step oscillation SP1, that is, with the counter electrode step oscillation SQ2. In the second line at the top right of FIG. 12, the empty symbol indicates that there is therefore no pointer display over the outer part of this spoke group Mia. Where a pointer is to be displayed, a step oscillation SQi must be selected for the counter-electrode ring arcs Qia / z, which results in the potential difference required for activation in relation to the step oscillations SPi at the locally assigned front electrode connection poles 11o, as in FIG. 12 registered above. In a second multiplex step, this activation shown in FIG. 12 for the simultaneous display of hour and minute hands 119 »12o is switched off and instead the activation described above for displaying a second hand 121 is switched on.
