Title of the invention i? F

Alphanumeric display arrangement Area of application

The invention relates to an alphanumeric display arrangement, in which an electro-optically active medium is excited between the electrodes and the counter-electrodes to display digits, characters, symbols and / or letters, which can also be made up of one or a plurality of Display elements in a horizontal and vertical arrangement

Characteristics of the known technical solutions

I ^{1 For} the reproduction of digital and alphanumeric symbols, a large number of differently acting electro-optical components are known in which a group, usually optically transparent, electrodes face one or more, not necessarily also optically transparent or even reflective counter-electrodes at a comparatively small distance between them For example, there is a gas or a gas mixture under reduced pressure which can be electrically excited to a visible discharge.

trochromatic, liquid crystalline and other materials are known.

Purely the practical use of all these components, which is usually done in very large numbers, in addition to the price and consumption of electrical energy, above all the effort for the control determines · The information for the characters to be displayed is available usually n-digit and binary-coded, with a time offset of the successive ones Information content for the individual positions in one dynamic memory before Connection diagram of the component intended for display decoded.From this, see specific for the component, In the decoding circuit, the signals are often sent directly, but mostly via isolation amplifiers that do not have any reaction to the connections of the component “The effort for these decoding and isolating circuits increases strongly with the number of component connections

Pure numbers has been used in a number of use cases a certain standardization of these circuits in connection with the component connections has already been achieved, so that some of these could be brought into the form of integrated circuits especially for the? -segment representation, with the seven (or eight, if a decimal point separates the digits) individually connectable from the outside, in Porm A stylized "8" arranged segment electrodes with optional interconnection of a common counter-electrode face. It is also known to split the 7- or 8-segment electrode arrangement into two to subdivide opposing groups, each comprising four of these segments. The one group of Electrodes are continuously drawn across all digits so that the areas between

Object of the invention

The aim of the Srfindunc is the creation of a universal role alphanuaeriechfin display arrangement that gets by with a Hini-Bua of connections for the representation of a character, a number, a »symbol or a letter, whereby neither due to the type of line routing unwanted conductor reductions occur in the bloctrodes or in the counter electrodes »illustration of Additional synbolon above and / or below, right and / or on the left side of the respective arrangement on an additional conductor the representation of mathematical and / or any; Spoken text® permitted

Explain the essence of the invention

The object of the invention is to achieve a lunine of connections per arrangement and in combinations of a large number of components by routing the electrodes and counter electrodes accordingly JO is designed

909840/057 '

The object is achieved according to the invention in that the alphanumeric display arrangement for elitro-optical Components for the representation of digits, characters, symbols and / or letters consists of segment electrodes

According to the invention, a number of 2 ⁿ conductors are arranged next to one another as an electrode, preferably in a vertical direction.They can be continued through any number of other display arrangements arranged next to one another and also form their electrode ^{there.An additional number of 2 n} conductors, which form the counter electrode, run through the arrangements in a level above or below, preferably in a horizontal direction.They can be continued through any number of display arrangements or rows of display arrangements arranged one below the other and there also form the counter electrode I ¹ Ur η can 2, 3, 4 can be used.

The function of the component is not impaired if the conductor routing of the 2 ⁿ electrodes and the 2 ⁿ counter electrodes are interchanged. According to the invention, it is proposed that the conductor guides of the electrodes and counter-electrodes also be created by single or multiple reflection.

The arrangement according to the invention of the conductors of the electrodes and the counter-electrodes allow the formation to any shape, so that in addition to a straight design, rounded shapes and the like can also be displayed can·

Switch on additional electrodes to generate dci ¹ special characters whose control information is also generated separately or additionally in allsenoinen in the work flow of the logic circuit.

In the control of a row of digits, therefore, only the switching on of these groups of four electrodes is required from character position to character position after every four switching cycles for the counter-electrodes necessary during these four switching clocks for the next line position are used for the counter electrodes at the same connections repeat in the same way. Likewise, characters or rows of characters can be placed one below the other that the groups of four of the electrode connections are located in the character positions arranged one below the other continue. In contrast to the o, a. Controlling a row of digits is essential for such an arrangement At the end of the row of digits, there is always the switchover to the new group of four of the counter electrodes of the next lower row of digits is necessary in which the same switching mode is repeated

The arrangement according to the invention also permits the illustration of a character with four, for example Conductors to swap the conductors of electrodes and counter electrodes and by single or multiple mirroring to form or by swapping.

According to the invention, the formation of the conductor guide can be achieved by combinations of the conductor guides of the electrode and counter electrode not necessary, preferably run vertically

JO The advantages of the alphanumeric display arrangement according to the invention consist in the fact that they are universal, so for example electro-optical components that as electro-optical medium gaseous, electroluminescent, electrophoretic, electroehromatic, liquid-crystalline i.a. Contain materials, can be used.

With it, a plurality of Anzeigeelsmenten can be in horizontal and vertical lease arranged for displaying, for example, a document text image "By using the additional symbol above and / or below / or right and and / or left side of the display element is any mathematical and / or Foreign language text can be displayed. By using the additional conductor, no adjacent character position is required for the display of the additional symbol, which is particularly advantageous when reproducing long text.

. With the alphanumeric display arrangement according to the invention, a minimum of control effort is required, since the electrode or counter-electrode is divided into a segment electrode ^{arrangement with 2 n} conductors per electrode, i.e. to the logical base number 2 ⁿ (n = 2 used in computing technology) , 3 ··· n) is traceable «

Example 4

Display panels according to FIG. 1 are generally manufactured with 2 ⁿ (n = 0.1 ... n) digits per row and rows of digits per panel. A typical arrangement for such tableaus are z · B · 8 (= 2 ^) rows of digits one below the other, each row with 52 (2- *) characters, so that on each. Tableau with a character arrangement according to the invention 256 (= 2) any alphanumeric characters, ie letters, numbers and other symbols mixed, with a constant monitoring cycle on the four (= 2) groups of the counter electrodes, which only 8 (ss 2? ) times are incremented at the end of the row of digits and 52 (= 2 ^) decoding circuits for synchronous control of the four (= 2) groups of the electrodes of the character positions arranged one below the other, which are each switched from character position to character position can be displayed or displayed

The names of the electrodes as segment electrodes on the one hand and as counter electrodes on the other hand do not represent a value designation, but serve only for explanatory purposes Distinction «In the case of gas discharge display panels, e.g. B. the terms "cathodes" and "anodes" are used for this. · However, the conductor tracks called counter electrodes can also be used in the form of segment electrodes · The designation "counter electrodes" was used here in the example for predominantly horizontal Through the signs running conductor tracks are chosen, which in their sum lead to the few contacts leading to the outside to lead·

Within the switch-on time of a counter electrode can the segment electrodes required to represent a character or a series of characters both at the same time as well as being switched on one after the other by the control system. Simultaneous activation due to the longer switch-on
