Description

La présente invention concerne un affichage digital comprenant un agencement d'électrodes. Plus particulièrement, la présente invention concerne l'affichage digital d'une indication de quantième dans une pièce d'horlogerie comprenant un agencement d'électrodes.The present invention relates to a digital display comprising an arrangement of electrodes. More particularly, the present invention relates to the digital display of a date indication in a timepiece comprising an arrangement of electrodes.

Dans le cas d'une pièce d'horlogerie du type montre-bracelet qui affiche l'heure au moyen d'une aiguille des heures et d'une aiguille des minutes qui se déplacent au-dessus d'un cadran, l'affichage de la date se fait, le plus souvent, au moyen d'un disque, dit disque des quantièmes, sur lequel sont reportées les indications de quantième et qui est entraîné par le mouvement de la pièce d'horlogerie. Les indications de quantième apparaissent typiquement au travers d'un guichet ménagé dans le cadran de la montre. Au lieu d'afficher l'indication de quantième au moyen d'un disque rotatif sur lequel sont imprimées les 31 dates, il a également déjà été proposé d'afficher la date de manière digitale au moyen d'un dispositif d'affichage numérique d'informations tel qu'une cellule à cristal liquide visible au travers d'un guichet. Dans ce cas, les indications de quantième qui sont comprises entre 1 et 31 sont successivement affichées au moyen de deux groupes juxtaposés de sept segments que l'on appelle communément digits à sept segments. Le digit de droite est habituellement utilisé pour afficher les unités des quantièmes, et le digit de gauche est utilisé pour afficher les dizaines des quantièmes. Un problème se pose ainsi avec les dates de 1 à 9 qui comprennent un seul chiffre. En effet, dans ce cas, seul le digit de droite est utilisé pour afficher cette indication de quantième, de sorte que cette indication de quantième apparaît décentrée par rapport au guichet dans lequel elle s'affiche. D'autre part, les groupes ou digits à sept segments fournissent un affichage qui est maintenant souvent considéré comme désuet et peu attractif.In the case of a wristwatch type timepiece which displays the time by means of an hour hand and a minute hand which move above a dial, the display of the date is most often made by means of a disc, called the date disc, on which the date indications are shown and which is driven by the movement of the timepiece. The date indications typically appear through an aperture in the dial of the watch. Instead of displaying the date indication by means of a rotating disc on which the 31 dates are printed, it has also already been proposed to display the date digitally by means of a digital display device. information such as a liquid crystal cell visible through a window. In this case, the date indications which are between 1 and 31 are successively displayed by means of two juxtaposed groups of seven segments which are commonly called seven-segment digits. The right digit is usually used to display the units of the dates, and the left digit is used to display the tens of the dates. A problem thus arises with dates from 1 to 9 which include a single digit. In fact, in this case, only the right digit is used to display this date indication, so that this date indication appears off-center with respect to the window in which it is displayed. On the other hand, the Seven-segment groups or digits provide a display that is now often viewed as outdated and unattractive.

Le document US 2001/002637 A1 divulgue un agencement d'électrodes dans lequel deux digits successifs ont des électrodes en commun. Par ailleurs, dans ce même document, chacun des trois digits comprend deux électrodes verticales supérieure et inférieure qui s'étendent à égale distance des électrodes latérales supérieures gauche et droite, respectivement des électrodes latérales inférieures gauche et droite. Enfin, toujours dans ce même document, chacun des trois digits comprend des segments qui s'étendent en oblique, c'est-à-dire non contiguës aux électrodes latérales supérieure et inférieure droites.The document US 2001/002637 A1 discloses an arrangement of electrodes in which two successive digits have electrodes in common. Moreover, in this same document, each of the three digits comprises two upper and lower vertical electrodes which extend at an equal distance from the upper left and right side electrodes, respectively from the lower left and right side electrodes. Finally, still in this same document, each of the three digits comprises segments which extend obliquely, that is to say not contiguous with the upper and lower right side electrodes.

Le document DE 32 14 174 A1 divulgue un affichage à deux digits juxtaposés séparés l'un de l'autre par des segments d'affichage formés chacun de deux points et disposés les uns au-dessus des autres respectivement à hauteur des électrodes supérieures, médianes et inférieures de chacun des digits.The document DE 32 14 174 A1 discloses a display with two juxtaposed digits separated from one another by display segments each formed of two points and arranged one above the other respectively at the height of the upper, middle and lower electrodes of each of the digits.

La présente invention a pour but de pallier les inconvénients mentionnés ci-dessus ainsi que d'autres encore en procurant un nouvel affichage comprenant un agencement d'électrodes permettant, en particulier, d'obtenir un affichage centré d'un nombre à un seul chiffre.The object of the present invention is to overcome the drawbacks mentioned above as well as others still by providing a new display comprising an arrangement of electrodes making it possible, in particular, to obtain a centered display of a single-digit number. .

A cet effet, la présente invention concerne un affichage à deux digits juxtaposés comprenant un agencement d'électrodes selon la revendication 1 annexée à la présente demande de brevet.To this end, the present invention relates to a display with two juxtaposed digits comprising an arrangement of electrodes according to claim 1 appended to the present patent application.

Des modes d'éxecution préférés sont divulgués dans les revendications dépendantes.Preferred embodiments are disclosed in the dependent claims.

Grâce à ces caractéristiques, la présente invention procure un affichage formé de deux groupes juxtaposés de segments que l'on appelle communément digits qui permet notamment d'afficher les chiffres 0 à 9 de manière centrée par rapport à ces deux digits. Par ailleurs, l'affichage selon l'invention permet également d'afficher les chiffres de manière plus précise et plus attractive. D'autre part, dans son mode de réalisation préféré, l'affichage comprend un total de 39 segments. C'est davantage que deux digits à 7 segments chacun, mais c'est nettement moins qu'un affichage matriciel, ce qui permet de continuer à utiliser une technologie d'adressage de type non-multiplexé qui offre des avantages en termes de contraste d'affichage et de coût de réalisation. Outre les chiffres de 0 à 9, l'agencement d'électrodes selon l'invention permet également d'afficher certaines lettres telles la lettre « M » qui est utile pour afficher les indications « AM » et « PM » lors du réglage d'une alarme ou du réglage initial de l'heure et de la date. Le digit de gauche permet également l'affichage de la lettre « Y » utile pour le réglage initial de l'année dans le cas d'une fonction de quantième perpétuel.Thanks to these characteristics, the present invention provides a display formed of two juxtaposed groups of segments which are commonly called digits which makes it possible in particular to display the digits 0 to 9 in a centered manner with respect to these two digits. Furthermore, the display according to the invention also makes it possible to display the figures in a more precise and more attractive manner. On the other hand, in its preferred embodiment, the display comprises a total of 39 segments. This is more than two digits with 7 segments each, but it is significantly less than a matrix display, which makes it possible to continue to use a non-multiplexed type addressing technology which offers advantages in terms of contrast. display and cost of production. In addition to the numbers from 0 to 9, the arrangement of electrodes according to the invention also makes it possible to display certain letters such as the letter “M” which is useful for displaying the indications “AM” and “PM” when adjusting the temperature. a alarm or initial time and date setting. The left digit also allows the display of the letter “Y” useful for the initial setting of the year in the case of a perpetual calendar function.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un mode de réalisation de l'affichage selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement en liaison avec le dessin annexé sur lequel :

  • la figure 1 illustre un affichage formé de deux groupes juxtaposés de sept segments selon l'art antérieur ;
  • la figure 2 illustre un affichage formé de deux groupes juxtaposés de segments selon l'invention, et
  • la figure 3 illustre diverses indications alphanumériques qu'il est possible d'afficher au moyen de l'affichage de la figure 2.
Other characteristics and advantages of the present invention will emerge more clearly from the detailed description which follows of an embodiment of the display according to the invention, this example being given purely by way of illustration and not limiting only in connection with the attached drawing on which:
  • the figure 1 illustrates a display formed of two juxtaposed groups of seven segments according to the prior art;
  • the figure 2 illustrates a display formed of two juxtaposed groups of segments according to the invention, and
  • the figure 3 illustrates various alphanumeric indications which can be displayed by means of the display of the figure 2 .

La présente invention procède de l'idée générale inventive qui consiste à repenser l'agencement des électrodes compris dans un affichage à deux digits juxtaposés permettant d'une part d'afficher les nombres formés d'un seul chiffre de 0 à 9 de manière centrée par rapport à ces deux groupements d'électrodes, et d'autre part d'afficher les chiffres de manière plus réaliste et plus attractive. Ce résultat est atteint grâce au fait que l'agencement d'électrodes proposé est dissymétrique, le digit de gauche ne présentant pas le même agencement que le digit de droite. En cela, la présente invention va à l'encontre du sens commun selon lequel les deux digits doivent avoir la même structure étant donné qu'ils sont utilisés pour afficher chacun les mêmes chiffres. Dans un mode de réalisation simplifié de l'invention, seul le digit de gauche est substantiellement modifié, le digit de droite demeurant un digit à sept segments classique auquel ne vient s'ajouter qu'une unique électrode supplémentaire. Ceci facilite donc la structuration des électrodes et permet de conserver inchangé l'adressage des électrodes du digit de droite.The present invention proceeds from the general inventive idea which consists in rethinking the arrangement of the electrodes included in a display with two juxtaposed digits making it possible, on the one hand, to display the numbers formed of a single digit from 0 to 9 in a centered manner. compared to these two groups of electrodes, and on the other hand to display the figures in a more realistic and attractive way. This result is achieved by virtue of the fact that the proposed arrangement of electrodes is asymmetrical, the left digit not having the same arrangement as the right digit. In this, the present invention goes against the common sense that the two digits must have the same structure since they are used to each display the same digits. In a simplified embodiment of the invention, only the left digit is substantially modified, the right digit remaining a conventional seven-segment digit to which only a single additional electrode is added. This therefore facilitates the structuring of the electrodes and makes it possible to keep the addressing of the electrodes of the right digit unchanged.

La figure 1 illustre un affichage comprenant un agencement d'électrodes selon l'art antérieur pour un affichage formé de deux groupes juxtaposés d'électrodes, ces deux groupes d'électrodes étant communément appelés digits. On observe que le digit de gauche, désigné dans son ensemble par la référence numérique générale 1, et le digit de droite, désigné dans son ensemble par la référence numérique générale 2, présentent le même agencement. Plus précisément, chacun des deux digits de gauche 1 et de droite 2 comprend une électrode supérieure 4a, 4b, une électrode médiane 6a, 6b et une électrode inférieure 8a, 8b, l'électrode médiane 6a, 6b s'étendant entre l'électrode supérieure 4a, 4b et l'électrode inférieure 8a, 8b. Les digits de gauche et de droite 1, 2 comprennent également une électrode latérale supérieure gauche 10a, 10 b et une électrode latérale inférieure gauche 12a, 12b, ainsi qu'une électrode latérale supérieure droite 14a, 14b et une électrode latérale inférieure droite 16a, 16b.The figure 1 illustrates a display comprising an arrangement of electrodes according to the prior art for a display formed of two juxtaposed groups of electrodes, these two groups of electrodes being commonly called digits. It is observed that the left digit, designated as a whole by the general numerical reference 1, and the right digit, denoted as a whole by the general numerical reference 2, have the same arrangement. More precisely, each of the two digits on the left 1 and on the right 2 comprises an upper electrode 4a, 4b, a middle electrode 6a, 6b and a lower electrode 8a, 8b, the middle electrode 6a, 6b extending between the electrode upper 4a, 4b and lower electrode 8a, 8b. The left and right digits 1, 2 also include an upper left side electrode 10a, 10 b and a lower left side electrode 12a, 12b, as well as an upper right side electrode 14a, 14b and a lower right side electrode 16a, 16b.

L'affichage comprenant un agencement d'électrodes selon l'art antérieur discuté ci-dessus permet d'afficher n'importe quel nombre compris entre 0 et 99 par activation des combinaisons d'électrodes appropriées. Un tel agencement d'électrodes est cependant considéré par beaucoup d'utilisateurs comme un peu désuet et peu attractif. Surtout, lorsque l'on souhaite n'afficher qu'un seul chiffre entre 0 et 9, seul un seul des deux digits est activé, habituellement le digit de droite. L'affichage du chiffre unique est ainsi décentré par rapport au groupe de deux digits, ce qui est peu satisfaisant en particulier dans le cas où cet affichage apparaît au travers d'un guichet 18 ménagé par exemple dans un cadran de montre pour l'indication de la date du jour ou autre.The display comprising an arrangement of electrodes according to the prior art discussed above allows any number between 0 and 99 to be displayed by activating the appropriate electrode combinations. Such an arrangement of electrodes is, however, considered by many users to be somewhat outdated and unattractive. Especially, when you want to display only one digit between 0 and 9, only one of the two digits is activated, usually the right digit. The display of the single digit is thus off-center with respect to the group of two digits, which is unsatisfactory in particular in the case where this display appears through a window 18 provided for example in a watch dial for the indication. of today's date or other.

Pour remédier à ce problème, la présente invention enseigne un nouvel agencement d'électrodes compris dans un affichage formé de deux groupes juxtaposés d'électrodes, ces deux groupes d'électrodes étant communément appelés digits. On observe que seul le digit de gauche, désigné dans son ensemble par la référence numérique générale 20, est substantiellement modifié par rapport à l'art antérieur, tandis que le digit de droite, désigné dans son ensemble par la référence numérique générale 22, conserve une structure assez semblable à celle d'un digit classique à 7 segments tel que décrit ci-dessus en liaison avec l'art antérieur.To remedy this problem, the present invention teaches a new arrangement of electrodes included in a display formed of two juxtaposed groups of electrodes, these two groups of electrodes being commonly called digits. It is observed that only the left digit, designated as a whole by the general reference numeral 20, is substantially modified with respect to the prior art, while the digit of straight line, designated as a whole by the general reference numeral 22, retains a structure quite similar to that of a conventional 7-segment digit as described above in connection with the prior art.

Plus précisément, le digit de gauche 20 comprend une électrode supérieure 24, une électrode médiane 26 et une électrode inférieure 28, l'électrode médiane 26 s'étendant entre l'électrode supérieure 24 et l'électrode inférieure 28. Préférentiellement, l'électrode supérieure 24, l'électrode médiane 26 et l'électrode inférieure 28 s'étendent horizontalement et à distance les unes des autres.
