Abstract

The invention relates to a device for providing a display or the like, which device is composed of a number of picture segments (2, 3) which are activated, e.g. made visible, or non-activated, e.g. made non-visible. The picture segments (2, 3) are, according to the invention, arranged to form a number of equal picture segment units (1) positioned side by side and comprising each a square with an inscribed geometrical figure (2), which by straight or arcuate parts define four identical corner segments (3) of the square, which picture segments are composed of the geometrical figure (2) and the four corner segments (3).

Description

503 357 2 utföringsform av en anordning enligt uppfinningen, och på vilka figur l är en planvy av en bildsegmentenhet och figur 2 är en display med en anordning uppbyggd av bildsegmentenheter enligt uppfinningen, figur 3 och 4 är en display med sanna anordning uppbyggd av konventionella bildsegmentenheter enligt två möjliga mönster, figurerna 5 och 6 är planvyer av två alternativa former av en bildsegmentenhet, och figurerna 7,8 och 9 är tvärsektioner av bildsegmentenheter enligt tre olika utföranden. 503 357 2 embodiment of a device according to the invention, and in which figure 1 is a plan view of an image segment unit and figure 2 is a display with a device built up of image segment units according to the invention, figures 3 and 4 are a display with true device built up of conventional image segment units according to two possible patterns, Figures 5 and 6 are plan views of two alternative shapes of an image segment unit, and Figures 7, 8 and 9 are cross sections of image segment units according to three different embodiments.

Figur l visar en bildsegmentenhet l, som även brukar kallas en pixel, och som enligt uppfinningen är uppdelad i fem LCD~element eller bildsegment, nämligen ett cirkelsegment 2 och fyra hörnsegment 3, och san har formen av en cirkel inskriven i en kvadrat. Bildsegmentenheten l är uppbyggd på konventionellt sätt med en ram 4, som har en kant utmed vilken anslutningar 5 till de olika bildsegmenten 2,3 är anordnade. Vid sannanställning av flera t.ex. 8x5 pixelenheter till en större bild så anordnas ramen 4 på konventionellt sätt runt bilden och ej runt enskilda pixel.Figure 1 shows an image segment unit 1, which is also usually called a pixel, and which according to the invention is divided into five LCD elements or image segments, namely a circle segment 2 and four corner segments 3, and which has the shape of a circle inscribed in a square. The picture segment unit 1 is constructed in a conventional manner with a frame 4, which has an edge along which connections 5 to the different picture segments 2,3 are arranged. In the case of true employment of several e.g. 8x5 pixel units for a larger image, the frame 4 is arranged in a conventional way around the image and not around individual pixels.

Figur 2 visar en display med en anordning i form av en siffra "8", som är bildad av ett fält med 5x7 bildsegmentenheter l hos displayen.Figure 2 shows a display with a device in the form of a number "8", which is formed by a field with 5x7 image segment units 1 of the display.

Anordningens krökta partier har fått en form scn1är särskilt lättläst genom att exempelvis bildsegment 10-15 hos tre bildsegmentenheter vid siffrans övre, högra hörn och bildsegment 9,12-15 hos tre bildsegmentenheter vid siffrans högra mittparti samt bildsegment 9,12-l4,l6,l7 hos tre bildsegmentenheter vid siffrans undre, högra hörn samt motsvarande bildsegmentenheter vid siffrans vänstra kant på ritningen är icke synliggjorda.The curved portions of the device have been given a shape which is particularly easy to read by, for example, image segments 10-15 of three image segment units at the upper, right corner of the digit and image segments 9,12-15 of three image segment units at the right middle portion of the digit and image segments 9,12-114, 16. 17 of three image segment units at the lower, right corner of the digit and corresponding image segment units at the left edge of the digit in the drawing are not shown.

Som jämförelse visas i figur 3 och 4 sanna siffra bildad på tvâ olika, möjliga sätt av kvadratiska bildsegmentenheter, som saknar uppdelningen i de fem bildsegmenten 2,3. Bokstaven blir som synes mycket kantig och svårläst. _ I stället för en bildsegmentenhet 1 i form av en i en kvadrat inskriven cirkel kan man använda en i en kvadrat inskriven fyrhörning 2', dvs en kvadrat, eller en i en kvadrat inskriven åttahörning 2", såsom visas i fig. 5 och 6, med hörnsegment 3'resp. 3".For comparison, Figures 3 and 4 show true numbers formed in two different, possible ways by square image segment units, which lack the division into the five image segments 2,3. The letter seems to be very angular and difficult to read. Instead of an image segment unit 1 in the form of a circle inscribed in a square, it is possible to use a quadrilateral 2 'inscribed in a square, i.e. a square, or an octagon 2 "inscribed in a square, as shown in Figs. 5 and 6. , with corner segment 3'resp. 3 ".

Figurerna 7-9 visar starkt förenklat i tvärsektion tre olika anordningar för åstadkcnnande av en display enligt uppfinningen.Figures 7-9 show, greatly simplified in cross section, three different devices for producing a display according to the invention.

Fig.7 visar ett hölje 21 med en framsida bestående av LCD-element 22 och en med lämplig färg anordnad, genomskinlig baksida 23, som är bakifrån belyst av en ljuskälla 24. Icke synliggjorda bildsegment hos LCD-elementen 22 framträder då klart även i mörker. 503 357 Fig.8 visar ett motsvarande hölje 21 med en framsida 25 med bildsegment 3 av t.ex. färgat glas. Bakom varje bildsegment och åtskiljda av mellanväggar 26 är en ljuskälla i form av glödlampor 27 anordnad.Fig. 7 shows a housing 21 with a front side consisting of LCD elements 22 and a transparent back side 23 arranged with a suitable color, which is illuminated from behind by a light source 24. Invisible image segments of the LCD elements 22 then clearly appear even in the dark. . Fig. 8 shows a corresponding housing 21 with a front side 25 with image segment 3 of e.g. coloured glass. Behind each image segment and separated by partitions 26, a light source in the form of light bulbs 27 is arranged.

Fig.9 visar en variant utan ljuskälla omfattande ett hölje 21 och en framsida 28 bestående av LCD-element, som är aktiverbara med värme, scm alstras medelst en rörlig laserstråle 29 på i och för sig känt sätt.Fig. 9 shows a variant without light source comprising a housing 21 and a front side 28 consisting of LCD elements, which can be activated with heat, which are generated by means of a movable laser beam 29 in a manner known per se.

Insidan av höljets baksida 30 är försedd med lämplig färg, som ger god kontrastverkan mellan synliggjorda och icke synliggjorda bildsegment.The inside of the back 30 of the housing is provided with a suitable color, which gives a good contrast effect between visible and invisible image segments.

Uppfinningen är självfallet inte begränsad till det här visade och beskrivna utföringsexemplet, utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade uppfinningstanken. Således kan varje bildsegmentenhet vara av det slaget där bildsegmenten har en minnesfunktion, så att en styrspänning kan upphöra sedan den aktiverat ett bildsegment, som kvarblir i aktiverat tillstånd tills en ny signal tillförs, san deaktiverar bildsegmenten. 'The invention is of course not limited to the exemplary embodiment shown and described here, but can be modified in several ways within the scope of the inventive concept defined in the claims. Thus, each pixel unit may be of the type where the pixels have a memory function, so that a control voltage may cease after activating a segment which remains in the activated state until a new signal is applied, which deactivates the segments.
