Definitions

  • the present invention relates to an alphanumeric display system in which the individual characters are composed of segments which are optionally made visible.
  • Such display systems have become known in particular from the technology of display with the aid of liquid crystals or electro-luminescence. With regard to the shape and arrangement of the segments, the known systems can basically be divided into the two versions shown in FIGS. 1 on the one hand and 2 and 3 on the other hand.
  • Figures 2 and 3 each show another known embodiment with 16 and 7 linear, i.e. segments each having a preferred axial direction, the embodiment according to FIG. 3 being suitable only for representing numbers.
  • the individual segments are preferably individually controlled via individual lines.
  • the readability can theoretically be increased arbitrarily by increasing the number of segments, but a greatly increased effort has to be accepted.
  • the number of feed lines can indeed be reduced, provided that the segments are not driven sequentially in time, rather than individually, but as crossing points of row and column electrodes.
  • such a matrix control has the disadvantage that the segments that remain invisible should become faintly visible, which reduces the contrast and thus the recognizability of the characters.
  • the individual segments are controlled individually and the leads to the segments have to be placed in the same plane as the electrodes, the leads for the segments inside the matrix must be between the edges of the segments on Edges of the matrix.
  • the object of the invention is now to use a relatively small number of segments to represent both large and small letters and individual special characters in such a way that they are easy to read for everyone.
  • the invention is based on the knowledge that the segments do not have to be selected either as a more or less wide line or as similar, matrix-like surfaces according to the previous custom. It relates to an alphanumeric display system according to the preamble of claim 1, which is characterized in that at least three different basic forms of segments are used.
  • the segments are arranged in such a way that, within each displayed character, all mutually adjacent segments abut one another along a line.
  • FIG. 4 shows the segment division according to the first example and a few selected characters which can be formed with this segment division.
  • FIG. 5 shows the segment division according to the second example and a few selected characters which could be formed with this segment division.
  • the total of 62 segments of the embodiment according to FIG. 4 have straight contour lines and are - predominantly irregular - areas with three, four, five, six or eight corners.
  • the lines through which the segments are controlled and which run in part I between the segments are not shown.
  • a maximum of 4 such lines run in the zones between two segments, whereby according to the current state of the art these parallel lines can be accommodated in a space of only 1 mm between two segments. This is of little concern when displaying characters with a height of approximately 10 cm. In the case of smaller characters, the specified minimum spacing can be reduced somewhat, but is still more important.
  • the 64 segments of the embodiment according to FIG. 5 have partly straight, partly circular contours. As in the embodiment according to FIG. 4, most segments are irregularly shaped and have surfaces with two, three, four or five corners.
  • FIGS. 4 and 5 on the one hand and FIGS. 1 to 3 on the other shows that the legibility and aesthetic effect in the embodiment according to the invention is considerably better than in the embodiments according to the prior art, although this favorable effect is somewhat more than double or triple the number of segments.
  • legibility and aesthetics cannot be expressed in numbers, it can be said that the increase in the effectiveness of the designs according to the invention compared to the prior art is greater than the effort caused by the increased number of segments.
  • legibility and aesthetics it must also be taken into account that the number of different characters to be displayed in the embodiments according to the invention is considerably larger than according to the prior art.
  • the legibility and the aesthetic impression could be increased with an arrangement of an even larger number of segments, and in particular the number of characters to be displayed with foreign accents and other special characters could be increased.
  • the same disadvantages would have to be accepted as those in the Together with the matrix-like arrangement according to FIG. 1 was pointed out.
  • the two selected exemplary embodiments thus represent good compromises between the number of segments on the one hand, the legibility and the aesthetic effect on the other hand, the invention of course not being tied to these two exemplary embodiments in any way.
