Description

La présente invention concerne un ensemble d'affichage comprenant un afficheur comportant une source lumineuse et un élément semi-transparent permettant de montrer l'afficheur uniquement lorsque celui-ci est activé.The present invention relates to a display assembly comprising a display comprising a light source and a semi-transparent element making it possible to show the display only when the latter is activated.

ART ANTERIEURPRIOR ART

Il est connu dans l'art antérieur des montres électroniques à aiguilles. Ces montres à aiguilles peuvent être munies d'un afficheur électronique du type LCD pour afficher des informations complémentaires. Ces informations complémentaires peuvent être la date ou l'heure sur un second fuseau horaire ou toutes autres informations pouvant être affichées par une montre électronique.It is known in the prior art for electronic watches with needles. These needle watches can be provided with an electronic display of the LCD type to display additional information. This additional information can be the date or the time in a second time zone or any other information that can be displayed by an electronic watch.

Généralement, le cadran de cette montre est un cadran en plastique ou en métal. Ce cadran présente une ouverture de sorte que l'afficheur puisse être vu par l'utilisateur. Par exemple, l'afficheur LCD sera collé sur la face inférieure du cadran pour être fixé à celui-ci.Generally, the dial of this watch is plastic or metal dial. This dial has an opening so that the display can be seen by the user. For example, the LCD display will be glued to the underside of the dial to be attached to it.

Pour améliorer l'esthétisme du cadran, celui-ci peut être réalisé en nacre. Toutefois, la présence d'une ouverture pour l'afficheur LCD gâche l'apport esthétique de la nacre.To improve the aesthetics of the dial, it can be made of mother-of-pearl. However, the presence of an opening for the LCD display spoils the aesthetic contribution of mother-of-pearl.

Pour remédier à cet inconvénient, une idée est de réaliser un ensemble d'affichage 1 qui consiste à disposer l'afficheur 4 et son circuit électronique 3 sous le cadran 2, ce dernier ne présentant pas d'ouverture. Pour un afficheur électronique caché sous un cadran, un cadran semi-transparent est nécessaire. Un tel cadran semi transparent permet dans un premier mode d'utilisation de camoufler le mouvement afin que seuls le cadran et sa décoration soient perceptibles lorsque l'afficheur est éteint, et dans un second mode d'utilisation, de permettre la lecture au travers du cadran de l'afficheur électronique lorsque ce dernier est enclenché.To remedy this drawback, one idea is to make a display assembly 1 which consists in arranging the display 4 and its electronic circuit 3 under the dial 2, the latter having no opening. For an electronic display hidden under a dial, a semi-transparent dial is necessary. Such a semi-transparent dial allows in a first mode of use to camouflage the movement so that only the dial and its decoration are visible when the display is off, and in a second mode of use, to allow reading through the dial of the electronic display when this last is engaged.

Afin de bien camoufler le mouvement et l'afficheur en mode éteint, il est envisagé d'utiliser un cadran qui absorbera la lumière ou la diffusera de manière à ce que l'utilisateur ne puisse voir au travers du cadran. Ainsi, il est envisagé d'utiliser une pièce de nacre fine (entre 0,01 et 1mm d'épaisseur). Cette pièce de nacre fine est esthétiquement intéressante et translucide; elle transmet la lumière tout en la diffusant. Cette propriété de diffusion permet de camoufler l'afficheur et le mouvement ; plus la diffusion est importante et plus le cadran paraîtra clair.In order to properly camouflage the movement and the display in off mode, it is envisaged to use a dial which will absorb the light or will diffuse it so that the user cannot see through the dial. Thus, it is envisaged to use a piece of fine mother-of-pearl (between 0.01 and 1 mm thick). This piece of fine mother-of-pearl is aesthetically interesting and translucent; it transmits light while diffusing it. This diffusion property makes it possible to camouflage the display and the movement; the greater the diffusion, the clearer the dial will appear.

Au contraire, lorsque l'afficheur est allumé, il est préférable que le cadran soit le plus transparent possible afin de transmettre une plus forte luminance de l'afficheur pour favoriser le contraste nécessaire à une bonne lecture.On the contrary, when the display is on, it is preferable for the dial to be as transparent as possible in order to transmit a greater luminance of the display to promote the contrast necessary for good reading.

De plus, il est préférable d'avoir le cadran ayant le moins de diffusion possible afin de conserver la finesse des détails illuminés de l'afficheur placé sous le cadran. Ainsi, plus la pièce en nacre sera diffusante et plus l'affichage paraîtra de mauvaise qualité.Moreover, it is preferable to have the dial having the least possible diffusion in order to preserve the fineness of the illuminated details of the display placed under the dial. Thus, the more the mother-of-pearl part diffuses, the more the display will appear of poor quality.

Il y a donc un compromis à réaliser sur la pièce de nacre pour avoir un équilibre entre déformation de l'image et blancheur du cadran.There is therefore a compromise to be made on the piece of mother-of-pearl to achieve a balance between distortion of the image and whiteness of the dial.

Un exemple de paramètre pouvant être modifié est l'épaisseur de la nacre qui permet d'adapter la propriété de diffusion afin de rendre la nacre plus claire. Si celle-ci est trop claire c'est-à-dire trop fine, l'afficheur électronique peut être visible lorsqu'il est éteint et la nacre apparaît foncée comme visible à la figure 1b. En contrepartie, si l'épaisseur de nacre est trop importante comme visible à la figure 1a, le cadran est plus joli car la nacre apparaît plus claire mais l'image de l'afficheur sera trop déformée.An example of a parameter that can be modified is the thickness of the mother-of-pearl which makes it possible to adapt the diffusion property in order to make the mother-of-pearl lighter. If it is too light, that is to say too fine, the electronic display may be visible when it is switched off and the mother-of-pearl appears dark as visible on the figure 1b . On the other hand, if the mother-of-pearl thickness is too great, as can be seen picture 1a , the dial is prettier because the mother-of-pearl appears lighter, but the display image will be too distorted.

Par conséquent, il est extrêmement difficile d'avoir un cadran en nacre sous lequel un afficheur peut être placé sans perturber l'esthétisme et la lisibilité des informations de l'afficheur.Consequently, it is extremely difficult to have a mother-of-pearl dial under which a display can be placed without disturbing the aesthetics and the readability of the information on the display.

Le document US2008/101161A1 divulgue un mode de réalisation (figures 1 et 9) d'un ensemble d'affichage comprenant un module d'affichage muni d'une source lumineuse pour afficher au moins une information et un module cadran permettant de montrer ladite information de l'afficheur uniquement lorsque celui-ci est activé. Dans ce mode de réalisation, le module cadran comprend un cadran réalisé dans un matériau translucide ou semi-transparent, sous lequel est disposé un élément semi-réfléchissant (54) permettant de réfléchir une partie de la lumière de ladite source lumineuse et transmettre une autre proportion de la lumière de ladite source lumineuse en empêchant la déflection des rayons lumineux par diffusion à travers le module cadran, ledit module d'affichage étant disposé sous ledit élément semi-réfléchissant.The document US2008/101161A1 discloses an embodiment ( figure 1 and 9) a display assembly comprising a display module fitted with a light source for displaying at least one item of information and a dial module making it possible to show said display item information only when the latter is activated. In this embodiment, the dial module comprises a dial made of a translucent or semi-transparent material, under which is arranged a semi-reflecting element (54) making it possible to reflect part of the light from said light source and transmit another proportion of the light from said light source by preventing deflection of the light rays by diffusion through the dial module, said display module being arranged under said semi-reflecting element.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

For a an electronic LED display 31, this comprises a substrate serving as a circuit 32 on which the light-emitting diodes (LEDs) are soldered and a separator 33 to improve the distinction of the details of the information displayed by the light-emitting diodes. This electronic display 31 is placed under the dial part 20.

Pour permettre d'avoir un afficheur électronique 31 qui n'est visible à travers le module cadran 20 que lorsqu'il est allumé, il est nécessaire que le module cadran 20 soit un élément semi transparent. A cet effet, le module cadran 20 comprend alors un cadran 21 dans un matériau translucide ou semi-transparent. Ce matériau translucide ou semi-transparent peut être de la nacre, de l'ambre, des météorites, de la corne, de l'os, du cuir, de la peau (comme par exemple de la peau de serpent ou de crocodile), du corail, du cartilage, des minéraux semi-transparents (silice, calcite), des verres semi-transparents ou teintés, des céramiques (oxydes, carbures, nitrures, borures) ou du bois. En effet, ces matériaux sont translucides ou semi-transparents lorsqu'ils se présentent en plaque fine. Dans le reste de la description, la nacre sera utilisée.To make it possible to have an electronic display 31 which is visible through the dial module 20 only when it is switched on, it is necessary for the dial module 20 to be a semi-transparent element. To this end, the dial module 20 then comprises a dial 21 in a translucent or semi-transparent material. This translucent or semi-transparent material can be mother-of-pearl, amber, meteorites, horn, bone, leather, skin (such as snake or crocodile skin), coral, cartilage, semi-transparent minerals (silica, calcite), semi-transparent or tinted glasses, ceramics (oxides, carbides, nitrides, borides) or wood. Indeed, these materials are translucent or semi-transparent when they come in a thin plate. In the rest of the description, mother-of-pearl will be used.

Avantageusement selon l'invention, le module cadran 20 comprend en outre un élément semi-réfléchissant 22. Cet élément semi réfléchissant 22 est utilisé pour avoir un cadran nacré 21 blanc et un afficheur électronique 31 camouflé lorsque celui-ci est éteint et, lorsque l'afficheur électronique 31 est allumé, avoir les informations de ce dernier qui sont bien visibles et bien détaillées.Advantageously according to the invention, the dial module 20 further comprises a semi-reflecting element 22. This semi-reflecting element 22 is used to have a pearly white dial 21 and an electronic display 31 camouflaged when the latter is switched off and, when the electronic display 31 is on, have the information of the latter which are clearly visible and well detailed.

A cet effet, l'élément semi-réfléchissant 22 est combiné avec un cadran 21 ayant une épaisseur donnée. En effet, l'épaisseur de la nacre est un paramètre qui permet d'ajuster les propriétés de diffusion afin de rendre la nacre plus claire. Un compromis doit être trouvé car si la nacre est trop claire, l'afficheur électronique 31 éteint peut être visible et la nacre apparaît de teinte foncée. Au contraire, si la nacre est trop épaisse, elle apparaît plus claire mais les détails des informations de l'afficheur électronique 31 seront déformés par la diffusion.For this purpose, the semi-reflecting element 22 is combined with a dial 21 having a given thickness. Indeed, the thickness of the mother-of-pearl is a parameter which makes it possible to adjust the properties of diffusion in order to make the mother-of-pearl lighter. A compromise must be found because if the mother-of-pearl is too light, the off electronic display 31 may be visible and the mother-of-pearl appears dark in color. On the contrary, if the mother-of-pearl is too thick, it appears more clear but the details of the information of the electronic display 31 will be distorted by the broadcast.

Dans le cas de la présente invention, le cadran 21 en nacre aura une épaisseur comprise entre 0.01 et 0.4mm avec des valeurs préférentielles à 0.1mm et 0.15mm. Cette gamme d'épaisseur de la nacre permet d'avoir un cadran 21 translucide qui transmet la lumière tout en la diffusant. L'épaisseur totale du module cadran 20 est, quant à elle, comprise entre 0.3 et 0.5mm.In the case of the present invention, the mother-of-pearl dial 21 will have a thickness comprised between 0.01 and 0.4 mm with preferential values at 0.1 mm and 0.15 mm. This range of mother-of-pearl thickness makes it possible to have a translucent dial 21 which transmits light while diffusing it. The total thickness of the dial module 20 is, for its part, between 0.3 and 0.5 mm.

Le fait d'avoir une telle combinaison d'un cadran 21 en nacre de faible épaisseur avec un élément semi-réfléchissant 22 permet de réfléchir une partie de la lumière et transmettre une autre proportion de la lumière sans déflection des rayons lumineux par diffusion. Par conséquent, lorsque l'afficheur électronique 31 est éteint, il est possible de rendre la nacre plus blanche car l'élément semi-réfléchissant 22 placé derrière le cadran 21 en nacre contribue à ce que ledit cadran 21 en nacre réfléchisse plus de lumière.Having such a combination of a thin mother-of-pearl dial 21 with a semi-reflecting element 22 makes it possible to reflect part of the light and transmit another proportion of the light without deflection of the light rays by diffusion. Consequently, when the electronic display 31 is off, it is possible to make the mother-of-pearl whiter because the semi-reflecting element 22 placed behind the mother-of-pearl dial 21 contributes to said mother-of-pearl dial 21 reflecting more light.

De plus, la diffusion totale du module cadran 20 est la diffusion du cadran 21 en nacre. Or, comme la diffusion varie proportionnellement avec l'épaisseur, un cadran 21 en nacre de faible épaisseur entraîne une faible diffusion qui permet de garder la finesse des détails de l'afficheur électronique 31 lorsque ce dernier est allumé. On combine donc l'avantage en termes de diffusion d'une nacre fine avec l'avantage en termes de blancheur d'une nacre épaisse.Moreover, the total diffusion of the dial module 20 is the diffusion of the dial 21 in mother-of-pearl. However, as the diffusion varies proportionally with the thickness, a mother-of-pearl dial 21 of small thickness leads to a low diffusion which makes it possible to keep the fineness of the details of the electronic display 31 when the latter is lit. The advantage in terms of diffusion of a fine mother-of-pearl is therefore combined with the advantage in terms of whiteness of a thick mother-of-pearl.

Dans un premier mode de réalisation, l'élément semi-réfléchissant 22 est un miroir semi-réfléchissant. Un tel miroir est constitué d'une couche de métal. Cette couche de métal peut être réalisée en Chrome ou Argent ou Aluminium ou tout autre métal ou alliage permettant la réalisation d'un tel miroir. Cette couche de métal présente une épaisseur comprise entre 1 et 50nm.In a first embodiment, the semi-reflecting element 22 is a semi-reflecting mirror. Such a mirror consists of a layer of metal. This layer of metal can be made of Chrome or Silver or Aluminum or any other metal or alloy allowing the production of such a mirror. This layer of metal has a thickness of between 1 and 50 nm.

Cette couche de métal peut être déposée directement sur le cadran 21 en nacre au niveau de sa surface non visible par l'utilisateur ou alors via un substrat. Pour cela, un substrat transparent en plastique ou autre est recouvert par cette couche de métal pour être ensuite collé au cadran 21 en nacre. La présence de ce substrat permet d'avoir une couche supplémentaire qui va rigidifier le module cadran 20 et permettre à celui-ci d'avoir une plus grande rigidité mécanique. Le module cadran 20 sera donc plus facile à manipuler.This layer of metal can be deposited directly on mother-of-pearl dial 21 at its surface not visible to the user or via a substrate. For this, a transparent plastic or other substrate is covered by this layer of metal to then be glued to the dial 21 in mother-of-pearl. The presence of this substrate makes it possible to have an additional layer which will stiffen the dial module 20 and allow it to have greater mechanical rigidity. The dial module 20 will therefore be easier to handle.

Un second mode de réalisation consiste en ce que l'élément semi-réfléchissant 22 comprend un miroir diélectrique. Un tel miroir diélectrique est composé d'une pluralité de couches de matériaux diélectriques déposées successivement. Les techniques de fabrication pour les miroirs diélectriques sont basées par exemple sur des méthodes de dépôt de couches minces. Les techniques communes sont l'épitaxie de faisceau moléculaire, le dépôt de faisceau d'ions, la déposition en phase vapeur, le dépôt physique de vapeur, et la pulvérisation. Ces couches de matériaux diélectriques ont des indices de réfraction et des épaisseurs différentes. De ce fait, par un phénomène d'interférences constructives, le taux de réflexion de la lumière peut être considérablement augmenté. Les miroirs diélectriques 22 les plus simples sont généralement colorés de sorte à pouvoir être utilisés pour colorer la nacre et ainsi apporter un plus en terme d'esthétisme. Il est toutefois possible d'obtenir des miroirs diélectriques de couleur neutre en procédant à une combinaison de couches de matériaux diélectriques plus complexes de sorte à réfléchir toutes les longueurs d'ondes du visible avec la même intensité. De cette façon, le cadran 21 en nacre garde sa couleur d'origine mais paraît plus éclatant pour l'utilisateur.A second embodiment consists in the semi-reflecting element 22 comprising a dielectric mirror. Such a dielectric mirror is composed of a plurality of layers of dielectric materials deposited successively. Manufacturing techniques for dielectric mirrors are based for example on thin film deposition methods. Common techniques are molecular beam epitaxy, ion beam deposition, vapor phase deposition, physical vapor deposition, and sputtering. These layers of dielectric materials have different refractive indices and thicknesses. Therefore, by a phenomenon of constructive interference, the light reflection rate can be considerably increased. The simplest dielectric mirrors 22 are generally colored so that they can be used to color the mother-of-pearl and thus provide more in terms of aesthetics. It is however possible to obtain dielectric mirrors of neutral color by combining layers of more complex dielectric materials so as to reflect all the visible wavelengths with the same intensity. In this way, the mother-of-pearl dial 21 retains its original color but appears brighter to the user.

L'utilisation d'un tel miroir diélectrique offre un meilleur rendement par rapport à un miroir sous forme de couche(s) métallique(s) car celui-ci absorbe une partie de la lumière.The use of such a dielectric mirror offers better efficiency compared to a mirror in the form of metallic layer(s) because the latter absorbs part of the light.

Dans une variante de ce second mode de réalisation, le miroir diélectrique de l'élément semi-réfléchissant 22 est réalisé en utilisant des couches diélectriques biréfringentes. Cette utilisation de couches diélectriques biréfringentes entraîne l'apparition d'un phénomène d'interférences constructives polarisées qui offre l'avantage d'avoir une couleur plus neutre rendant la nacre plus blanche. Un tel miroir constitué de couches diélectriques biréfringentes est appelé polariseur réflectif et permet de transmettre une polarisation pendant qu'il en réfléchit une autre.In a variant of this second embodiment, the dielectric mirror of the semi-reflecting element 22 is made using birefringent dielectric layers. This use of birefringent dielectric layers leads to the appearance of a phenomenon of polarized constructive interference which offers the advantage of having a more neutral color making the mother-of-pearl whiter. Such a mirror made up of birefringent dielectric layers is called a reflective polarizer and makes it possible to transmit one polarization while it reflects another.

Ces polariseurs réflectifs ou miroirs diélectriques peuvent se présenter sous la forme d'un film, c'est à dire d'une mince couche de matière telle une feuille. Le fait de se présenter sous la forme d'un film permet, lorsque ces polariseurs réflectifs ou miroirs diélectriques sont associés au cadran en nacre, d'avoir une plus grande rigidité mécanique. La partie cadran 20 sera donc plus facile à manipuler. Ce film peut être souple ou rigide et être réalisé en plastique ou dans un matériau tel que le verre ou tout autre matériau utilisable.These reflective polarizers or dielectric mirrors can be in the form of a film, that is to say a thin layer of material such as a sheet. The fact of being in the form of a film makes it possible, when these reflective polarizers or dielectric mirrors are associated with the mother-of-pearl dial, to have greater mechanical rigidity. The dial part 20 will therefore be easier to handle. This film can be flexible or rigid and be made of plastic or a material such as glass or any other usable material.

Il est également possible que ces polariseurs réflectifs ou miroirs diélectriques soient directement réalisés sur le cadran 21 au niveau de sa surface non visible par l'utilisateur, un film rigide ou souple étant collé par-dessus pour augmenter la rigidité du cadran 21.It is also possible for these reflective polarizers or dielectric mirrors to be made directly on dial 21 at its surface not visible to the user, a rigid or flexible film being glued on top to increase the rigidity of dial 21.

Cette variante est astucieuse par le fait que de tels polariseurs réflectifs sont généralement utilisés dans des afficheurs électroniques pour le recyclage d'énergie ou pour être utilisés comme miroir polarisant d'afficheurs réflectifs. L'utilisation de tels polariseurs réflectifs pour augmenter la blancheur d'une nacre n'est ainsi pas prévue.This variant is clever in that such reflective polarizers are generally used in electronic displays for energy recycling or to be used as a polarizing mirror for reflective displays. The use of such reflective polarizers to increase the whiteness of a mother-of-pearl is thus not provided for.

Par ailleurs, cette variante présente l'avantage d'être disponible commercialement sous forme de film plastique. Il devient envisageable de laminer le film sur la nacre évitant ainsi l'utilisation de procédés de dépôts de couches minces complexes et onéreux.Furthermore, this variant has the advantage of being commercially available in the form of a plastic film. It becomes possible to laminate the film on the mother-of-pearl, thus avoiding the use of complex and expensive thin layer deposition processes.

Dans la figure 2, l'élément semi-réfléchissant 22 est représenté sous la forme d'un film ou substrat portant soit un miroir semi-réfléchissant soit un miroir diélectrique, la version de l'élément semi-réfléchissant 22 directement réalisé sur le cadran 21 n'est pas représentée.In the figure 2 , the semi-reflecting element 22 is represented in the form of a film or substrate carrying either a semi-reflecting mirror or a dielectric mirror, the version of the semi-reflecting element 22 directly produced on the dial 21 is not not represented.

Dans une variante du premier et du second mode de réalisation, l'ensemble d'affichage comprend en outre un film opaque 40 placé entre l'afficheur électronique 31 et le module cadran 20 comprenant le cadran 21 en nacre et l'élément semi-réfléchissant 22. En effet, derrière le cadran 21 il est préférable d'avoir un mouvement dont la couleur est uniforme sous peine d'avoir des disparités de tons du cadran en nacre. Le film 40 sert ainsi à cacher des vis et autres pièces réfléchissantes qui se trouvent dans le mouvement. Cela évite que celles-ci soient visibles par l'utilisateur. Ce film opaque 40 présente une ouverture au niveau de l'emplacement en regard de l'afficheur électronique 31 pour que les informations de l'afficheur électronique 31 puissent être visibles par l'utilisateur. La couleur noire est choisie pour mettre en valeur la nacre et obtenir un fond bien uniforme.In a variant of the first and second embodiments, the display assembly further comprises an opaque film 40 placed between the electronic display 31 and the dial module 20 comprising the mother-of-pearl dial 21 and the semi-reflecting element 22. In fact, behind dial 21 it is preferable to have a movement whose color is uniform, otherwise there will be disparities in the tones of the mother-of-pearl dial. The film 40 thus serves to hide screws and other reflective parts which are found in the movement. This prevents them from being visible to the user. This opaque film 40 has an opening at the location facing the electronic display 31 so that the information from the electronic display 31 can be seen by the user. The black color is chosen to highlight the mother-of-pearl and obtain a very uniform background.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and/or improvements and/or combinations obvious to those skilled in the art can be made to the various embodiments of the invention described above without departing from the scope of the invention defined by the appended claims.
