Description

[Detailed description of the invention] electric) k 禾嘱1 The invention relates to electronic display devices intended for the visual display of special symbols, particularly regarding alphanumeric characters. Regarding the location.

Furthermore, the invention comprises an active display means consisting of one or several elements, the optical properties of which are A table that can be changed as a function of an electrical excitation signal selected and controlled by an electronic control circuit. Related to display devices.

To illustrate these elements, reference will now be made to a liquid crystal type electron/photocell. Main departure As we will see later, Ming means, for example, a set of electro-light emitting diodes, usually LEDs, and English. or corresponding to the above definition. Regarding other display devices.

Background technology In particular with regard to the present invention, French application no. FR-A-2458857 is well known. Ru. The display device described in this document consists of electrodes of a liquid crystal cell or each other. It has a shape consisting of closely spaced straight line segments, bounded by lines and columns. A set of modules, each composed of an electroluminescent diode that is in contact with a field, is include.

In graph design, this device is not completely satisfactory. Because this This device is used only for writing in the form of writing that is connected to one another. It is possible to display the In addition, this device does not allow modules to be written in lowercase or uppercase letters. European patent application 'IJEP O146285 describes other types of display devices, namely: has n rows and p columns (in the example of this description, n equals 5 and p equals 3) A display device is described which is essentially constructed in the form of a matrix of points.

The pixels of this matrix, i.e. each pattern forms an individually assignable electrode. The earliest patterns to Rix pixels are modified relative to each other. Matrix of low order like this While we wish to absolutely preserve the quality of (typically 5x3) When considering space, attempts were made to increase the number of pixels. At this time, rectangular pixels and especially square pixels From a standard matrix shape containing shape pixels, all identical; arranged and defined in a homogeneous shape. It started naturally by being taught. The purpose of this invention is to By cutting almost all of them so that they are visually the same, we can divide this pixel into four parts. Ru. As a result, the composition essentially consists of several repeating groups, each of which Each consists of four isosceles triangles. Observe the outline and enclosure of such groups and basically rectangular ones whose joints form a grid of patterns or matrices. It is easy to see that it is new.

It should be noted that the configuration of this device is strictly compliant with the definition of IJ wax display. A very regular and organized structure with dense, identical groups and repeating pixels. It remains a concept.

This electro-optical display concept presents significant difficulties. The format of characters that can be displayed depends on the Ultimately, it is determined from the beginning by the IJ hook position of the electrode or pixel. this Starting from a well-determined plan, the user can When planning which pixels to throw away, you have the possibility to choose. Therefore, the capacity of the device Confined to the initial pattern, it helps the user visualize the stylized characters. It is impossible to do so.

As a result, the device proposed in this patent application, by increasing the number of pixels, M) Although it responds to the desire to increase the resolution of Ux-shaped display devices, it is extremely limited. It is understood that there are limits. Actual user of this device and results The purchaser will now purchase the most appealing form as close as possible to the special form or personal handwriting. You will be able to write characters in a certain format.

European Patent Application No. EP 0180685 differs, especially in the last embodiment. A conceptual device is provided to partially address this problem. The first purpose is text By improving the character design, the inventor of this device no longer imposed the burden on the electrodes. Not from the plan, but from the result to be obtained, that is, from the letters and numbers themselves, or The idea was simply to respond to electrodes.

This means that the resulting pixels are in an irregular format and repeat systematically in rows and columns. That's why it is arranged in an irregular way without returning, and this pixel is for the most part They have different contours.

This type of device is called a "mosaic". The reason is that the composition of its ingredients is Formed from many pixels with different contours (circular, linear, angular...) This is because they are complementary and fit into each other. What you should be careful about is Until now, the distribution of pixels that is physically and non-uniformly spread or the electrode that surrounds the entire surface of the device has been This is because it is not considered in comparison with the specified matrix configuration. such a device The style is particularly similar to the colored stained glass windows seen in ancient stained glass windows in churches in the West. Regarding the arrangement of glass plates.

This device has a big problem.

The first thing to note is that the fact that the stylized characters are more sophisticated ``In such a substantial way that it is necessary to be associated with electronic circuits.'' an increase in pixels that irreversibly increases the price of a complete and equipped device. It is about leading.

The characters obtained and shown suffer from even poorer definitions and suffer from several shortcomings, as noted below. have

As shown in the attached Figure 2, especially the appearance, and therefore the design of those characters. Indication text such as “A” indicating a defect, point or mark (code 10) that affects the quality of the work. letters appear.

Furthermore, "noise lines" such as the reference numeral 11 in FIG. appear.

Each basic pattern is effectively composed of electrodes that are electrically isolated from neighboring electrodes. and each pattern can be coupled to the electronic control device by its own electrical coupling. It's necessary.

Such bonding can be achieved by photolithography-based electrodes on a substrate covered with a conductive layer. As a result, this bond is formed by a track configured to It tends to cause a change in the optical properties of the liquid crystal located between the parts. Therefore Such a combination appears simultaneously on the cell as a displayed alphanumeric character, and this again This causes a decline in display quality.

To alleviate this, each of the bonds can be removed in a way that makes them invisible (Fig. 2a) Cover the cathode and divide it into several very sharp branches or make an electrical connection at the electrode part only. It was proposed to consider an extremely complex cathode that covers but does not include the joint.

In both cases it is complex to implement and very expensive.

In addition, the device according to European Patent Application No. EP 0180685 Although clearly improved, it is still very limited. The reason is that lowercase letters are visually This is because it is not possible.

It also shows the inherent difficulties in sizing numbers and displayed characters as a function of their size. vinegar. This dimension therefore changes the already installed equipment for different sizes of the site. It can only be corrected by

The present invention also aims to meet these difficulties by providing an excellent definition that does not have the disadvantages of the above-mentioned types. For example, Helvetica, which is design. Halbfett Provides a display device that Furthermore, in order to keep manufacturing costs relatively low, this device has a low pixel count. is the minimum.

The invention further provides a display device that addresses the problem of character size at the lowest possible cost. The purpose is to

Summary of the invention Thus, it is an object of the present invention to provide an electronic display device of the type described below. .

The grid of its mixed mosaic configuration is similar to the puzzle method and nests inside each other. formed by a pattern representing disparate complementary contours arranged to create a Partially cut the basic pattern with mosaic to form chopped mosaic It is characterized by being divided into light-receiving zones.

According to another feature of the invention, the light-receiving zone can be covered by a chain zone to erase the basic pattern. The mosaic is formed to allow smaller surfaces to be removed. can be provided in place.

The chain band is straight and all positions are independently perpendicular to the reading sensor on the device. Direct or parallel are also specified.

Preferred embodiment Referring to FIG. 1, a liquid crystal cell forming the active display means of a device according to the invention is shown. is shown. This cell 1 has a front plate 2 and a transparent back side, as in a known style. It comprises plates 3 and a frame 4 that connects and seals the plates together. This sealed frame The chamber 4 is a hermetically sealed chamber in which a mixture 5 of liquid crystal, for example a dichroic substance, is held. Define volume. The front plate 2 and the back plate 3 form the substrate, each having an internal surface anode. 6a and cathode 6b, which are transparent and made of a mixture of, for example, indium tin. composed of things. The front plate 2 and the back plate 3 usually have a dielectric layer (not shown) in the same way. Supports parallel layers.

Furthermore, the anode 6a is formed by photolithography on the front plate 2 and the back plate 3 in the same way as the cathode 6b. It includes an electrical connection such as a cathode formed by Such electrical coupling is However, each is coupled to an electronic control circuit (not shown). Furthermore, in this example 1 adds a diffuse reflector or dot transmitter element 7 for the desired display mode. including.

The function of such cells is now well known. One anode 6a and one cathode 6b A portion of liquid crystal placed between such an anode and a cathode when a potential difference is applied between them This liquid crystal part of the display cell creates a light contrast area between the active and inactive parts. Change the configuration to change the light characteristics that create differences in brightness. This is explained in detail below write down

As explained above, devices currently known on the market include a segmented anode 6a. It is designed to be able to display relatively stylized characters.

At the same time, as shown in FIG. The alphanumeric characters will be displayed. Such defects are indicated in the form of dots or marks and are It doesn't seem to be active in position, and the characters displayed seem to be "swallowed" in places. Sea urchins appear.

Difficulties of this kind therefore generate particularly unfavorable effects, and devices of this type are indicating (e.g. a destination) in a public place such as a train station or airport saloon be detrimental to the commercial attractiveness of the device when it is known to be an enabling purpose. I understand that.

This kind of drawback gives many users the illusion of poor quality caused by premature use. make an impression.

Additionally, relatively clear single-stroke text that is typically visible when a person approaches a display device. can be viewed in addition to or within the display. Like this- The brush corresponds to the electrical connection numbered 11 in FIG. 2a.

In order to avoid the appearance of such a brush, such a part of the cathode should not be connected to the electrical connection 11. One technique is to divide the cathode 6b in a special manner so that it does not face each other. death However, each basic pattern has The cathode 6b has its own electrical connection appearing in the free space left on the substrate of the cathode 6b. The concept is even more complex, and such cathodes can easily be expensive as a result. I understand.

Another solution, as shown in FIG. 2a, is to divide each electrical connection 11 into several more distinct It is divided into two branches 11a, which, at least as a result, are not clearly visible from a certain distance.

Here again, it is possible to obtain such a branch by means of photolithography for the production of display means. It can be seen that there is no additional reduction in the cost of the cell.

In FIGS. 3 and 6, plan views of two mosaics according to the invention are shown. General Such a mosaic pattern, commonly called a "pixel", consists of an electrode such as anode 6a. holds true in this case. In analog systems, such a pattern is appropriate. consists of an electroluminescent diode placed on a solid support or It is established from other display means that can be managed.

The layout of the basic pattern of pixels according to the present invention is suitable for mosaics, especially mixed mosaics. Responding well to clarity, such patterns have disparate complementary contours, i.e. round, Such a The patterns are arranged to nest within each other in a manner similar to that of a puzzle. note It should be noted that all such patterns are regular in one direction or the other. They are arranged irregularly and without regard to order, without any repetition.

From the basic mosaic pattern m of Figures 3 and 6 (not all referred to) m9 indicates that the device according to the invention uses the Latin alphabet in uppercase and lowercase letters. They fit together and relate to each other in a manner that allows the display of all alphanumeric fields, such as characters.

Certain letters, like the numbers 0 to 9, are from European languages such as Germanic and Norman languages. , and all such characters have individual emphasis, including underlining. can be linked. Advantageously each of the mosaics of both of these embodiments , was formed in order to be able to display characters similar to the “Helvetian alphabet” form. Ru.

Furthermore, the mosaic M of the basic pattern m+-,, (m, to m,) is several pieces in the mosaic. Intellectual tradition consisting of a combination of mosaic M of Words that are superimposed or coded in modules that allow the display of words. Enable all punctuation marks to be displayed in group format for overlapping Ru.

By splitting such a mosaic (the behavior will be explained later), one The basic pattern m+-, is incorporated and arranged in groups G, to G,, The basic pattern in each group is a very small area left in the basic pattern. It should be noted that at the parallel poles of Y, they are very closely connected. It is.

Pattern group G 1-ri is arranged in rows, karari, and columns C3 to C3. It will be done.

Separated basic patterns mlt mz and m emphasize Germanic and Nordic letters. possible. Basic patterns m1 and m3 are aligned and extensions of columns C2 and C5 respectively provided above. The basic pattern m2 has the appearance of a substantially rectangular ring and the central row C8 is arranged substantially below the basic patterns m1 and m3.

Rows L1 to L6 of groups G, to G, have at least three characteristic areas A, B. , C, respectively, and the final region forms the above enhancement.

Area A is the visualization or tangible area of the fourth dimension of uppercase letters, while area B is the visualization or tangible area of the fourth dimension of uppercase letters. It is an area of visualization. For area C, the last table shows downward strokes and underlining. In particular, regions A, B and C each have five suitable aligned columns.

Regions A and B are conveniently included in the first embodiment of FIG. and 3 rows, the selection of such odd numbered rows is “B”, “3” or “8”. The groove portion 20 is specially shown in FIGS. 4g to 41. It is centered in relation to a horizontal transverse bar 22, which is shown separately.

Furthermore, in area A for uppercase letters and area B for lowercase letters, odd numbered lines are You can have uppercase and lowercase letters in figures 4b, 4d, 4f and 4g. Fourthly, as shown in the figure, it can be displayed substantially in the center.

Furthermore, in each unique characteristic group G, -,, (G, to G,), each group This pattern (e.g., pattern m) is replaced by an adjacent pattern or pattern in this case. From m, to m7, the separation Y is small, i.e. about 10 x 10. -’m (10 pIm) to 5 Qx 10-'m (50, m). That's it This distance has the essential function of electrically isolating neighboring patterns, and The width of the separating insulating interval E is formed on the mosaic. Here are the patterns for each group. placed very close to each other such as It looks like it's been done.

From figure 4a to jlE4, as can be seen in the letters and numbers in the figure, The spread distance Y does not appear in the displayed characters.

Each group G,-9 is formed by at least two elementary patterns connected adjacently. formed and at least partially separated from each other by an insulating spacing E.

Preferably, this extension distance Y is as short as possible considering practical conditions and selective production. selected to be small.

In the preferred embodiment of the present invention shown in FIG. A group of turns includes separating gaps in a straight line configuration.

In addition, each characteristic group G, to G. is the neighborhood group or separation zone b+− (from b+ vinegar. ), and each separating zone is in fact separated from the group by A conductive layer on the substrate between adjacent groups of anodes 6a is provided without such The substrate is constituted by a plate 2.

Separator, crow. preferably all have the same convergence is approximately 1.2×10 −3 m (1.2 mm). Typically 1. 5x 10 -3m (1,5 reports) is selected.

The widths of the separation bands forming the values X, i.e. the different characteristic groups G1 to G, are the same. Width of gap or insulation interval E1 left between adjacent basic patterns within a group is in any case clearly greater than the value Y. In the present invention, the value X is less than the value Y by 2 5 to 120 times larger.

R is at least greater than 15, in other words, the width of the separation band is left between the patterns. The ratio R between the values X and Y (R=X/Y) is satisfied if the separation distance Y is 15 times greater than the separation distance Y. It has been valued for providing the results that it can.

Preferably the value R is chosen equal to 30, where X = 1.5X 10-3m (1 , 5+++m> and Y is equal to 50 x 10-'m (50m). lastly preferred Alternatively, the separation distance Y is chosen to be less than 100XIO-'m (100#).

Generally, in the embodiments of FIGS. 3 and 6, the mosaic according to the invention consists of two adjacent groups. Separators placed between loops are usually left between patterns in such groups. The separation configuration is shown as showing a width X that is greater than a separation distance Y.

Furthermore, in this example, all of the basic patterns are applied in area A as well as across areas. even if the are combined in parallel. In the case of the present invention, the mosaic containing 152 basic patterns is Only 5 of them are isolated, and about 97% of the basic patterns are grouped in all mosaics. It can be determined that the group is organized into a group.

This choice of group organization has important functional consequences, as is well understood. 4a to 4. offers the possibility of displaying complete special style characters. From the separator, b7 is the receiver. For electrical connection elements 30 between groups G, , forming a light zone region, i As shown in the sb diagram, the basic pattern m+-,.

A preferable path is formed from the periphery of the display means to the periphery of the display means.

Such a separation band 1)l-n is completely isolated corresponding to the cathode 6b shown in FIG. As easily formed, such a separation zone 'E)l-n is very clearly shown in Figure 3. Such a cathode 6b forming a clearly demarcated free region appearing in the conductive conductor 6b A corresponding “cutout” area 40 without contacting provides a separation strip where electrical connections are placed. Adapted so that it is placed facing the. These regions are thus optically receptive. Being dynamic, electrical connections 30 do not appear on the display during alphanumeric visualization.

Furthermore, the mosaic M, that is, the arrangement of the different basic patterns m1-n within the pattern is mostly such that the minutes intersect on or within the active display means at the four separators b+-1'l. provided to. Separation zone b1-1 is at least at the level of the point of intersection I (Figure 3a) are separated from each other by an angle α greater than 60 degrees.

The value of this angle α is the value at which the appearance of defects as defined below begins to disappear noticeably. handle.

Preferably angle α is approximately equal to 90 degrees. In a preferred embodiment, pattern G The external contour of each group of I-n is substantially straight; such a contour is preferred. are substantially rectangular, and such continuous separation parts S1 to S, , are located on the right side of each It opens from the left horizontal edge and from the top and bottom edges, making it an edge-to-edge mosaic. Cross KuM. This is especially true for areas A, B, and C from the vertical separation part SI to 84. It is true for the regions A and B for the horizontal separation parts S and S8. Ru.

However, throughout the mosaic there are separate strips of crows. and continuous separation or division The separation parts S1 to 87 are vertical or flat with respect to the sensor for reading characters on the mosaic. organized into rows.

With reference to a straight line or horizontal reading, the continuous separating section or the dividing separating section S1 to S, and the dividing strips formed are defined to be essentially vertically and horizontally oriented. It is possible to clarify what will be done.

A display device according to the invention, especially for characters displayed by devices known today. Defects such as dots or marks 10 that appear can be erased. Referring to Figure 2a, the public You can see the details of the basic pattern of a knowledge display device.

The appearance of defect 10 in such a layout can be explained by a combination of several phenomena. I can explain.

Initially, at a small distance with respect to the display device, the defect is as an arc of a circle or a circle of radius R, It is expressed geometrically as touch a point on the curve. In the case of the present invention, the radius R1 is left between different basic patterns. It is observed that the separation distance a is already greater than the separation distance a. Therefore, at short distances Even so, the drawback 10 is already noticeable with respect to the spacing left between the patterns. child Such defects and such spacing are different from the display character defects, i.e. Appears in the same light mode with letters and comparison method.

At larger distances, at the ends or at focal points of different basic patterns, the light “corrupts”. An eclipse phenomenon occurs, i.e. a loss of clarity, and the eye can no longer discern such points. This results in a tendency to see the rounded end f.

Therefore, the defect 10 at this distance is made tangible under the shape of a circle with radius R2. It increases considerably. This radius R2 is much clearer than the radius R1 of the defect that can be seen at a short distance. Obviously big.

Thus, at larger distances, the spread between the gap a and the radius 2 of the defect 10 From now on, the defect 10 appears to be much superior to the gap a.

In addition, on the contrary, in the configuration of the mosaic according to the invention, as shown in FIG. For example, tg3. b+S, b+9 At a short distance surrounding the circle to and b, from the width X of the separation strip b13 + +8-20 The radius of a small value -, appears.

Therefore, the circle does not appear at a short distance and is no longer noticeable compared to the width of the separation zone bl-1. Since it is not, it no longer forms.

Furthermore, at large distances, the "corrosion" of light will cause such an arc to Since r tends to come quite close to this point or the end of group Gl-h, , becomes unimportant.

Therefore, the round enclosure at the intersection I has a value substantially equal to the width X of the separating strip, -1 represents the radius r2. Therefore, the alphanumeric characters displayed in this configuration have small round boxes. Practically no defects appear even at the smallest distances.

7 is oriented parallel and/or perpendicular to the displayed character reading sensor. , Mosaic M is displayed on all panels in the sensor section as represented in Fig. 3, that is, in the vertical direction. oriented in the direction of

This device has also been found to improve the appearance of displayed characters.

Such a mosaic M, depending on its composition, has a lowercase letter (see Figures 4d to 4f). ) is a visualization or highlighting element in which the emphasis element is uppercase, as in the Latin alphabet. This effectively changes the characters provided in the different alphabets. Again, this possible Gender is explained by the device in groups of basic patterns. of the same group The addition of the basic pattern of replenishment in the center is the basic pattern in such groups. This can be done by means of a device which is coupled outwardly to the pattern, the emphasis element of which is Such a Not distinguishable in uppercase alphanumeric bodies using groups.

Further, the separation strip b+-n and therefore the continuous female part or the divided separation part S1 to S, are at the intersection I. is located so that it is found outside the tangible area of the branches of characters that appear vertically or horizontally. It is also specified so that it can be used.

Referring now to FIG. 6, a female portion or read sensor according to a second embodiment of the present invention. There are dividing portions S5 to 87 defined in the parallel direction, that is, horizontally. This fruit In the embodiment, it has a width X equal to the dividing portions listed up to 7.

From now on, referring to Figures 7 to 10, the mosaic in Figures 3 to 6 The procedure by which a grid is created, the division of such a mosaic into bands → e, i.e., light reception separation Or explain how the division and separation was performed.

Referring now to FIG. 7, a first structure of a mosaic according to the invention is constructed. One can see a grid with a base T, referred to as the first grid. . This base grid T1 allows the display of lowercase letters as well as the display of the first set of small numbers. This is for forming region B where

Very advantageously, as shown in FIG. 8, such a base grid T1 is It is partially duplicated, especially the portion above the symbol T2. Dot-dash line L in Figure 7 e shows the top of the replicated base grid T, then the base grid T.

“Glue” the top. The dividing line Lc is divided into two lines in order to duplicate the base grid. After combining grids T1 and T2, the distorted insulation spacing will be within one and the same mosaic. In order to finally accept and agree on the character representations of different dimensions, .

Finally, the dividing line LC is located at the intersection of the insulation spacing E1 in the warped direction.

Obtain a duplicate structure of the base grid like this and place it especially in front of the first grid T, After obtaining the additional grid by referring to the second grid T2, as described above, Finally, by the continuous separation section or division separation section S1 to S, arranged at the initial stage, Proceed with the division of grid T.

As can be seen in FIG. As a result, all of T3 is divided and thus forming different groups of basic patterns within the mosaic. Seen in Figure 9 As shown in FIG. Partially cover the turn. In addition, such a light receiving separation section or division separation section is the most Overlap and hide all basic patterns on small surfaces to get a better representation of your design It is blacked out on Figure 9. Separation parts or division separation parts S1 to 8 in such a band 7 is photosensitive, the smallest surface basic pattern is erased, and the level of electrical coupling is It is no longer necessary to be aware of the means of causing problems on the electronic level as well as on the electronic level. There isn't.

Advantageously, the mosaic according to the invention has at least two separations or horizontal divisions. The separation codes S, and 86 are included, and these S, and S have the maximum density of the basic pattern. Conveniently placed next to an area.

are placed in contact with the regions 100 and 120 of maximum concentration of ion.

Basic patterns for pixels that require electrical coupling that is difficult to access in this way It becomes much easier to provide Things to note are shown in the diagram below The two horizontal separations or divisions S, and SF, are lower case as shown in the remaining figures. It is arranged as one of the pixels L4 to form an intermediate horizontal bar.

In addition, such a mosaic can have a third horizontal separation or water above the lowercase letters. placed in contact with line L3 forming a group of patterns specifically for displaying flat bars. It includes a dividing/separating section S7 located therein.

Preferably, such a separation or division m s is placed directly on the line L3.

It is placed in contact with the mosaic rows C1 and 05 for forming the brush strokes.

The separators or divisions respectively define within them five columns C1 to C1, and the columns C, , C, and C3 form vertical or central columns, respectively, to form downward strokes. Ru. Such central portion C3 and columns CI, C5 exhibit equal widths. further downward Three such columns C, , C3 and C6 for stroke strokes are reduced to 2 by intermediate columns C2 and C4. separated into pairs 2, the middle columns C2 and C1 are of equal width between them, and the three columns C , , C, and C3.

FIG. 10 shows the divided grid T4 that is the result of the processing in FIG. Add an insulating interval E to form the directional stroke or the beginning of certain alphanumeric characters.

More precisely, as shown in FIG. Contains four display areas for numbers.

Advantageously, the mosaic according to the invention can be formed by forming alphanumeric characters of average size, especially a set of large letters. a first display area A corresponding to the formation of letters and numbers (FIGS. 11 to 18); Such a first area A covers all the columns and the formation of the last downward stroke of the capital letter and Mosaic regarding the exception which is the last line L6 corresponding to area C for the formation of the underline bar Use the line of orgasm.

Such mosaics allow the display of alphanumeric characters of large dimensions, i.e. uppercase letters and large numbers. It includes a second area E for allowing The display characters can be seen in FIGS. 19-26.

Regarding area E, area A is contained within area E in this way, and area E covers the entire mosaic. It has been found that all surfaces are used.

The third characteristic display area of such a mosaic is located in the first position described below. Area B essentially allows for the display of small numbers and lowercase letters. lowercase letter However, the upper part of a certain character, the downward stroke part of area A, and the part of area C used for parts. In this way, this area B is included in area A, and the underlined area C placed directly on top of the

Characters that can be displayed are represented by area B as shown in FIGS. 27 to 34.

The mosaic according to the invention further includes a fourth area F, which provides an area B. Displaying smaller numbers in a different position than they should be displayed, i.e. essentially slightly above allow you to do so.

Region F has a nest inside region B, which overlaps component region A. To area F Characters that can be displayed are shown in FIGS. 35 to 38. Therefore, such a mosaic Iku are of the same family (numbers, uppercase letters, lowercase letters), different symbol sizes, characteristics It can be seen that it includes at least two characteristic regions forming a . Even more precisely different sizes It includes at least two characteristic areas A, B for the formation of the digits. even more accurate in a simple manner for the formation of numbers of three different sizes, i.e. large, medium and small. includes characteristic areas A, B, and E.

Finally the formation of numbers, especially the small numbers on different levels at the top and bottom respectively A fourth characteristic region F is included for the formation of the character. one and the same group in a very advantageous way lid, i.e. the divided final grid T shown in FIG. (medium, large) and different sizes within the same family of letters (uppercase and lowercase). It has been found that a mosaic is provided which is applied to the display of the image. Alphanumeric like this It is possible to advantageously deal with the problem of given dimensions of Furthermore, it is possible to erase display cells when displaying the time, for example. do.

This device and this process can be applied to one and a very substantial number of patterns on the same mosaic. be able to provide services. This device has a low compounding rate, i.e. a certain basic pattern. The patterns have a composite rate that is electrically coupled between the patterns such that the pattern corresponds to the composite rate. It can be applied to electronic display devices.

In such a case, the cathodes 6b provide a unique electrical connection that is electrically isolated from each other. However, it is no longer possible to use a single block (continuous) as for the cathode shown in Figure 5. do not have.
