  • the present invention also relates to a segmented display means adapted for control by an inventive controlling system, and an indicating system comprising an inventive controlling system and a segmented display means.
  • Patent publication US 4 647 924 teaches a segmented display means adapted to show letters belonging to the Arabic alphabet.
  • a display means according to this publication is able to take into account, to some extent, whether the letter to be presented is located at the beginning of a word, in the centre of the word or at the end of the word, or whether the presentation shall consist of the freestanding letter.
  • Patent publication US 5 407 355 also teaches a letter display means for showing Arabic letters. However, it is difficult to comprehend how the same display means unit is capable of showing an arbitrary letter in accordance with the segmentation described in this publication.

  • Figure 3 is intended to show that symbols completely different to alphabetic characters can be included by the table 15, such as symbols or indicators belonging to an indicating instrument 151 , such as a gauge or technically equivalent means for instance, thereby enabling a display means belonging to the instrument panel of an automotive vehicle to be addressed and controlled by a controlling system according to the present invention.

  • Different ways of segmenting a display means are known to the art.
  • One way is to form a display means from the dots in a dot matrix.
  • the resolution of the display means increases with the number of dots or points included in the matrix.
  • the drawback with this method is that it becomes more difficult to address and control the display means with an increasing number of matrix dots.
  • the present invention provides a possibility of readily addressing a large number of segments and hence an inventive controlling system is well suited to include a table of characters that can be shown on or presented by a display means consisting of segment-forming matrix points.
  • the table may also include characters that can be shown on a display means consisting of segment-forming triangles, where groups of four triangles form squares or oblongs which build a matrix, as shown in figure 4.

  • This enables a controlling system to include standardised characters or symbols that have already been entered into the first memory space 12a during manufacture and that are therewith available to the system, whereas the second memory space is available to user-adapted characters and symbols that can be entered and changed in accordance with user requirements.
  • the predefined format of the first data bits 31 needs to be adapted to the construction or compilation of the table 15 used.
  • the converting or transforming unit 12 need then be adapted to the way in which an addressed symbol can be reproduced on a specific segmented display means 2.
