Definitions

  • the invention relates to an electronic display device intended to display particular signs, such as in particular alphanumeric characters.
  • the active display means consists of one or more elements the optical characteristics of which can vary as a function of an electrical excitation signal, selectively controlled by a circuit of electronic control.
  • the invention can be applied, in certain of its characteristics, for example to a display device comprising a set of light-emitting diodes, more generally designated under the British abbreviation "LED” or even to any other display device meeting the above definition.
  • an electronic display device comprising a set of modules which are respectively constituted either by the electrodes of a liquid crystal cell, or by light-emitting diodes, and which have the form of straight lines arranged adjacent and at the end, by lines and by columns.
  • patent application EP 0 146 285 describes a display device of another type, that is to say structured essentially in the form of a matrix of points, with n rows and p columns (n being equal to 5 and p equal to 3, in this example).
  • the pixels of this matrix that is to say the most elementary patterns which each form an individually addressable electrode, have been modified with respect to the pixels of the matrices.
  • most classic points only in order to increase the resolution.
  • the designers of this matrix while wanting to imperatively keep the qualities of low order matrices (typically 5x3), tried to increase the number of pixels.
  • they therefore quite naturally started from a classic matrix form, comprising rectangular pixels, and in particular square pixels, by definition all identical and distributed in a homogeneous manner.
  • the resulting structure therefore essentially consists of several repeating groups, each composed of four isosceles triangles. By observing the outline or the envelope of these groups, we can clearly see the appearance of the original rectangles whose meeting constitutes the grid or grid of the matrix.
  • Patent application EP 0 180 685 partially addresses this problem by providing a device of a different design.
  • the primary goal being to improve the aesthetics of the characters, the designers of this device started, no longer from an imposed diagram of electrodes, but from the result to be obtained, namely letters and numbers themselves for only then conform the electrodes.
  • the pixels obtained are irregularly shaped and are arranged in a disorderly manner, without systematic repetition in rows and columns, these pixels having for the major part of them different contours.
  • This type of device is called “mosaic” because of its composite-looking structure, formed by many pixels with heterogeneous contours (rounded, straight, angled, ...), but complementary and in concordance, overlapping one in the others. It is noted that a logical and uniformly distributed distribution of the pixels or electrodes is not taken into account over the entire surface of the device, as opposed to the matrix structures defined above.
  • This type of device is similar to the arrangement of the pieces of tinted glass that are found in the old stained glass windows of places of worship, especially in the West.
  • This device has major drawbacks.
  • each elementary pattern being constituted by an electrode which is electrically isolated from the neighboring electrodes, it is necessary to connect each pattern to the electronic control system by its own electrical connection.
  • connections are formed by tracks which are structured, like the electrodes, by a photolithographic process on a substrate covered with a conductive layer and they are therefore liable to vary the optical characteristics of the liquid crystal lying between them and a part. of the counter electrode. It is therefore understood that these connections can appear on the cell, at the same time as the alphanumeric characters displayed, which again contributes to deteriorating the quality of the display.
  • the device according to this application EP 0 180 685 although providing a marked improvement in the appearance of the characters, still remains very limited since it does not allow the display of lowercase letters. It also has the essential drawback of having to be sized according to the size of the numbers and letters to be displayed. This dimension is therefore fixed and it can only be modified by changing the device already installed in favor of another, of different size.
  • the object of the present invention is therefore to respond to these drawbacks by providing an improved display device capable of visualizing much more stylized characters, for example close to the Helvetica Halbfett character, of excellent (aesthetic) definition. , free from defects of the type mentioned above, but in which the number of pixels can be minimized to obtain a low cost price.
  • the present invention also aims to provide a display device making it possible to respond to the problem of sizing the characters at a cost even as low as possible.
  • a liquid crystal cell which forms the active display means of the device according to the invention, this cell 1 comprising, in a known manner, a transparent front blade 2 and a transparent blade 3 and joined together by a sealing frame 4.
  • the sealing frame 4 defines a sealed volume in which a mixture is trapped 5 composed of a liquid crystal and, for example, a dichroic dye.
  • the front 2 and rear 3 blades which form the substrate carry on their internal face respectively electrodes 6a and a counter electrode 6b, the latter which are transparent being constituted for example by a mixture of indium oxide / tin.
  • the front blades 2 and rear 3 generally also carry a dielectric layer and an alignment layer which are not shown here.
  • cell 1 further comprises an element 7 of the reflector-diffuser or transflector type, depending on the display mode that is desired.
  • the devices currently known on the market include electrodes 6a cut and arranged in order to be able to display relatively aesthetic characters.
  • a technique consists in cutting the counter-electrode 6b in a particular way so that no part of this counter-electrode is opposite an electrical connection 11.
  • each elementary pattern having its own electrical connection which leaves in the free space left on the substrate, between this pattern and the neighboring pattern, it is easily understood that the design of the counter-electrode 6b is all the more complicated, and that the latter is therefore all the more expensive.
  • connection 11 As shown in FIG. 2a, another solution consists in dividing each connection 11 into several branches 11a, these branches which are thinner therefore being much less visible, at least from a certain distance.
  • FIGs 3 and 6 there is shown in top view the two embodiments of the mosaic according to the invention, the patterns of this mosaic which are generally called "pixels" being constituted in this case by electrodes 6a.
  • these patterns can be constituted by diodes electroluminescent arranged on a suitable support, or by any other display means which can be activated electrically.
  • the arrangement of the elementary pixel patterns according to the invention responds well to the definition of mosaic, and in particular of composite mosaic, since it will be noted that these patterns have heterogeneous and complementary contours, namely rounded, rectilinear or oblique with combinations indifferent, these patterns being arranged in concordance to overlap one another, similar to a puzzle.
  • all these patterns are arranged in an irregular and disorderly manner without any systematic repetition of rows or columns, in one direction or another.
  • the elementary patterns m 1 to m n of the mosaics of FIGS. 3 and 6 are shaped and are associated with one another so that the device according to the invention can display a whole range of alphanumeric characters, such as the letters of the Latin alphabet in upper and lower case, some of the letters used in European languages such as Germanic or Nordic languages, as well as the numbers 0 to 9, all these characters can be associated with their respective accentuation, including understood the underlines.
  • each mosaic of these two embodiments is shaped to be able to display characters close to the "Helvetica Halbfett" style.
  • the mosaic M of elementary patterns m 1-n makes it possible to display all the punctuation marks so that the combination of several mosaics M together, juxtaposed or superimposed in modules, allows the display of intelligible messages, made up as structured sentences or as a group of coded words.
  • the groups of patterns G 1-n are arranged in rows L1 to L6 and in columns C1 to C5.
  • the isolated elementary patterns m 1 , m 2 and m 3 allow the accentuation of Germanic and Nordic characters.
  • the elementary patterns m 1 and m 3 are aligned and are respectively provided in the extension of the columns C1 and C5.
  • the elementary pattern m 2 which has the appearance of a substantially rectangular ring is disposed substantially below the elementary patterns m 1 and m 3 and facing the central column C3.
  • Lines L1 to L6 of groups G 1 to G n delimit at least three characteristic zones A, B and C respectively, a last zone D forming the abovementioned accentuations.
  • Zone A is the zone for viewing or materializing a first size of capital letters
  • zone B is the zone for viewing small letters
  • Zone C is, for its part, the zone allowing in particular the display of the end of the legs and the display of the underlines, the zones A, B and C each having five columns suitably aligned.
  • Zones A and B advantageously comprise, in the first embodiment of FIG. 3, respectively five and three lines of characteristic groups, this choice of odd numbers of lines allowing the display of letters or numbers such as "B", “ 3 “or” 8 ", the hollowed parts 20 are centered with respect to a horizontal crossbar 22, as shown particularly in Figures 4g to 4i.
  • the spacing distance Y which separates each elementary pattern (for example the pattern m 4 ) from the adjacent pattern (s), in this case the patterns m 5 to m 7 is low, i.e. of the order of 10.10 -6 meters (10 ⁇ m) to 50.10 -6 meters (50 ⁇ m).
  • This distance has the essential function of electrically isolating neighboring patterns and it forms the width of the insulation spaces Es on the mosaic. that separate the patterns from each other.
  • the patterns in each group are therefore arranged relative to each other very closely, and seem, even at a small distance, contiguous to each other. As can be seen in the letters and numbers in Figures 4a to 4k, this distance distance Y does not appear in the characters displayed.
  • each group G 1 -n is formed by at least two elementary patterns joined together and separated from each other, at least in part, by an isolation space Es.
  • the spacing distance Y is chosen as small as possible taking into account the feasibility conditions and the chosen yield.
  • each group of patterns at least in zones A and B has a spacing interval of rectilinear shape.
  • each characteristic group G 1 to G n is separated from the neighboring group or groups by separation bands b 1-n , each separation band being in fact provided, in the case of a liquid crystal cell, by l absence of a conductive layer on the substrate between the electrodes 6a of the neighboring groups; this substrate being constituted by the blade 2.
  • the separation strips b 1 to b n preferably all have the same width X, this width preferably being of the order of 1.2 ⁇ 10 -3 meters (1.2 mm). Typically, it is chosen equal to 1.5.10 -3 meters (1.5 mm).
  • the value X that is to say the width of the separation bands which form the different characteristic groups G 1 to G n , is in any case clearly greater than the value Y which is the width of the interval or isolation space Es left between the adjacent elementary patterns in the same group.
  • the value X is chosen between 25 and 120 times greater than the value Y.
  • the distance of spacing Y is chosen to be less than 100 ⁇ 10 -6 meters (100 ⁇ m).
  • the mosaic according to the invention has a chopped structure such that the separation strips formed between two adjacent groups always have a width X which is greater than the spacing distance Left there between the motives of these groups.
  • all the elementary patterns are organized into groups; namely joined together in pairs, at least in part at the limit of joining.
  • the mosaic comprising 152 elementary patterns, only 5 of them being isolated, it can be determined that in the whole mosaic, approximately 97% of the elementary patterns are organized in groups.
  • the separation strips b 1 to b n constitute optically passive regions and form, between the groups G 1 to G n , preferential passages of the electrical connection elements 30, from the elementary patterns m 1-n to the periphery of the means d display, as shown in Figure 3b.
  • the mosaic M namely the arrangement of the different elementary patterns m 1-n therebetween, is provided in such a way that at most four separation bands b 1-n intersect on or in the active means d 'display.
  • the separation strips b 1-n at least 'at their point of intersection I ( Figure 3a), are angularly offset from each other by an angle ⁇ greater than 60 degrees.
  • this angle ⁇ corresponds to that from which the appearance of defects, as will be defined below, begins to decrease significantly.
  • the angle ⁇ is at most equal to 90 degrees.
  • the outer contour of each group of patterns G 1-n is substantially rectilinear, this contour preferably being substantially rectangular.
  • the bands b 1-n are in fact formed by continuous partitions or cutouts S 1 to S n which are formed on the major part of the display means, these continuous partitions S 1 to S n passing through the mosaic from start to finish. to open its lateral edges respectively right and left, and its upper and lower edges. This is particularly true in areas A, B and C for vertical partitions S 1 to S 4 , and in areas A and B for horizontal partitions S 5 to S 8 .
  • the separation bands b 1 to b n and the continuous separations or cutouts S 1 to S n are organized perpendicular or parallel to the direction of reading L of the characters on the mosaic.
  • the continuous partitions or cutouts S 1 to S 7 and the separation strips which they form can be defined as being oriented in essentially vertical and horizontal directions.
  • the display device according to the invention makes it possible in particular to eliminate the defects such as the dots or marks 10 which appear on the characters displayed by the devices currently known.
  • FIG. 2a shows in detail the arrangement of the elementary patterns of a known display device.
  • the defects can be geometrically represented as an arc of a circle or a circle of radius R1, the circle being tangent to the ends or points of the various elementary patterns which converge towards the point of intersection i .
  • the radius R1 is already greater than the spacing distance a which is left between the different elementary patterns.
  • the defect 10 at this distance increases considerably to materialize in the form of a circle of radius R2, this radius R2 being very much greater than the radius R1 of the defect which is visible at a short distance.
  • the circle envelopes the point of intersection I at the level of the separation strips for example b13, b18, b19 and b20, has a radius r 1 of a value less than the width X of the separation strips b 13,18-20 .
  • the envelope circle does not appear at a short distance and no longer forms a defect, since it is no longer preponderant with respect to the width of the separation bands b 1-n .
  • the envelope circle of the point of intersection I has a radius r 2 of value substantially equal to the width X of the separation strips b 1-n .
  • the definition of the characters and the readability are improved when the separation bands b 1-n and more particularly the continuous separations or cuts S 1 to S n which form the hash of the mosaic are oriented parallel and / or perpendicular to the reading direction of the displayed characters, the mosaic M being oriented over a whole panel display assembly, in the direction in which it is represented in FIG. 3, namely vertically.
