Description

Module de commande et d'affichage pour véhicule automobile et procédé de fabrication  Control and display module for a motor vehicle and method of manufacture
La présente invention concerne un module d'interface homme-machine comprenant un organe d'affichage, notamment pour véhicule automobile. En particulier un tel organe d'affichage peut consister en un symbole rétroéclairé ou un écran par exemple multifoncton de type TFT ou à affichage LCD. Cet organe d'affichage peut comporter une dalle tactile permettant la saisie d'informations telles que des commandes. Plus précisément, un tel module d'interface trouve une application pour les commandes situées à proximité du conducteur, au niveau de la planche de bord ou de la console centrale située entre les sièges des passagers avants du véhicule automobile. Sous sa forme d'écran, l'organe d'affichage peut par exemple commander des fonctions telles que la climatisation, un système audio, un système de téléphonie ou encore un système de navigation. Sous sa forme d'un symbole, l'organe d'affichage peut par exemple commander des fonctions simples telle que par exemple la fonction « warning ». Lorsque ces organes d'affichage sont associés à de telles commandes, nous obtenons des organes de commande et d'affichage. L'invention se rapporte plus précisément au procédé de fabrication dudit module de commande et d'affichage et au module lui- même. The present invention relates to a human-machine interface module comprising a display member, in particular for a motor vehicle. In particular, such a display member may consist of a backlit symbol or a screen, for example a TFT-type multifoncton display or an LCD display. This display member may comprise a touch screen for inputting information such as commands. More specifically, such an interface module finds an application for the controls located near the driver, at the dashboard or the central console located between the front passenger seats of the motor vehicle. In its screen form, the display member may for example control functions such as air conditioning, an audio system, a telephony system or a navigation system. In the form of a symbol, the display member may, for example, control simple functions such as, for example, the "warning" function. When these display members are associated with such commands, we obtain control and display devices. The invention relates more specifically to the manufacturing method of said control and display module and to the module itself.
Ces écrans ou symboles peuvent avantageusement être recouverts d'une dalle supérieure tactile, transparente, permettant la saisie de commandes par les utilisateurs. La dalle tactile permet de localiser l'appui par exemple d'un doigt de l'utilisateur par exemple en utilisant une technologie capacitive ou résistive. La localisation de l'appui peut alors être mise en relation avec des champs de saisie correspondant à différentes options (accepter, refuser, retour au menu précédent, etc.). These screens or symbols can advantageously be covered with a top touch panel, transparent, allowing the input of commands by users. The touch screen allows to locate the support for example of a finger of the user for example using a capacitive or resistive technology. The location of the support can then be linked to input fields corresponding to different options (accept, refuse, return to the previous menu, etc.).
Pour la protection des modules d'interface, comprenant des organes d'affichages tels que les symboles et/ou les écrans, munis ou non de dalles tactiles il est d'usage de les For the protection of the interface modules, including display members such as symbols and / or screens, with or without touch screens, it is customary to use them.
il couvrir d'une plaque transparente et d'un cadre, qui au moyen d'un film opaque découpé délimite soit la fenêtre dans laquelle l'écran est visible ou .la représentation graphique du symbole. L'empilement de ces différentes couches conduit à l'obtention d'un écran d'épaisseur importante, tout en représentant des surcoûts à la production. he cover with a transparent plate and a frame, which by means of a cut opaque film delimits either the window in which the screen is visible or .the graphic representation of the symbol. Stacking these different layers leads to obtaining a screen of significant thickness, while representing additional costs to production.
Afin de pallier au moins partiellement les défauts précédemment cités, l'invention a pour objet un procédé de fabrication de module d'interface, le module d'interface comprenant un organe d'affichage, destiné à être visible à travers une dalle transparente, caractérisé en ce qu'il comporte les étapes :  In order to at least partially overcome the above-mentioned defects, the subject of the invention is an interface module manufacturing method, the interface module comprising a display element intended to be visible through a transparent slab, characterized in that it comprises the steps:
- une encre opaque est sérigraphiée sur certaines zones d'un film pour délimiter des cadres ou symboles,  an opaque ink is screen printed on certain zones of a film to delimit frames or symbols,
- de la colle est déposée entre le film côté encre sérigraphiée et une dalle transparente du module d'interface, - le film est collé et laminé sur la dalle transparente du module d'interface. glue is deposited between the screen-printed ink film and a transparent slab of the interface module; the film is glued and laminated on the transparent slab of the interface module.
Le procédé de fabrication permet d'affranchir le module d'interface d'un film supplémentaire exclusivement dédié à la délimitation d'un cadre dans lequel l'organe d'affichage est visible, et le remplace par une couche d'encre sérigraphiée plus fine et moins coûteuse. Le module d'interface résultant peut donc être plus fin et moins coûteux au final. The manufacturing process makes it possible to free the interface module of an additional film exclusively dedicated to the delimitation of a frame in which the display member is visible, and replaces it with a layer of finer screen-printed ink and less expensive. The resulting interface module can therefore be thinner and less expensive in the end.
Le procédé peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison. The method may further have one or more of the following features, taken alone or in combination.
Il comporte en outre une étape supplémentaire dans laquelle la dalle transparente sur laquelle le film a été collé et laminé est placée sous vide pour dégazer des bulles emprisonnées. It further comprises an additional step in which the transparent slab on which the film has been glued and laminated is placed under vacuum to degasble trapped bubbles.
Le film utilisé est un filtre polarisant. The film used is a polarizing filter.
Il comporte une étape supplémentaire dans laquelle une encre translucide est sérigraphiée sur des portions exemptes d'encre opaque du film. It has an extra step in which a translucent ink is silkscreened on portions free of opaque ink from the film.
Il comporte une étape supplémentaire d'application d'une couche de remplissage entre la ou les encres sérigraphiées et la colle déposée entre le film côté encre sérigraphiée et la dalle transparente du module d'interface. L'épaisseur de la couche de remplissage est choisie entre 5 et 50 micromètres de sorte à correspondre à quelques épaisseurs d'encre sérigraphiée. It comprises an additional step of applying a filler layer between the screen-printed inks and the adhesive deposited between the screen-printed ink film and the transparent plate of the interface module. The thickness of the filler layer is chosen between 5 and 50 microns so as to correspond to a few thicknesses of screen-printed ink.
La couche de remplissage est réalisée en vernis durcissant aux ultraviolets, et en ce que le vernis est durci avant le collage et le laminage du film. The filler layer is made of ultraviolet-curing varnish, and the varnish is cured before bonding and rolling of the film.
Le vernis utilisé est à faible viscosité et à fort mouillage avec la ou les couches d'encre sérigraphiées.  The varnish used is low viscosity and high wetting with the screen printing ink layer (s).
L'invention se rapporte aussi au module d'interface obtenu selon ledit procédé, comprenant un organe d'affichage, destiné à être visible à travers une dalle transparente transparente, sur laquelle est collé et laminé un film, caractérisé en ce que le film comporte une couche d'encre opaque sérigraphiée pour délimiter des cadres ou symboles.  The invention also relates to the interface module obtained according to said method, comprising a display member, intended to be visible through a transparent transparent slab, on which is glued and laminated a film, characterized in that the film comprises an opaque ink layer silkscreened to delimit frames or symbols.
Le module d'interface peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison. The interface module may further have one or more of the following features, taken alone or in combination.

- la figure 4 est un schéma simplifié des différentes étapes du procédé.  FIG. 4 is a simplified diagram of the various steps of the method.
Sur toutes les figures les mêmes références s'appliquent aux mêmes éléments.  In all figures the same references apply to the same elements.
La surface de l'organe d'affichage considéré permet (au moins localement) de définir une normale orientée positive vers l'extérieur du module, dans la direction de l'utilisateur. Les termes « au-dessus », « au-dessous » et équivalents tels qu'utilisés ultérieurement seront définis par rapport à cette normale. The surface of the display member considered allows (at least locally) to define a normal oriented positive towards the outside of the module, in the direction of the user. The terms "above", "below" and equivalents as used later will be defined relative to this normal.
La figure 1 montre de façon schématique une vue en coupe d'un module d'interface 1 , comportant un film 3 en train d'être appliqué sur une dalle 5 transparente d'un organe d'affichage 7 du module 1 , représenté ici sous forme d'écran. FIG. 1 schematically shows a sectional view of an interface module 1, comprising a film 3 being applied to a transparent slab 5 a display member 7 of the module 1, shown here in the form of a screen.
La dalle 5 transparente est ici une dalle tactile, par exemple capacitive ou résistive, et est apposée sur la surface supérieure de l'écran 7 d'affichage, qui peut être par exemple un écran à cristaux liquides, à diodes organiques OLED ou à plasma. L'organe d'affichage 7 peut aussi alternativement être une boîte à lumière, un guide de lumière ou un écran diffusant placé au dessus d'une source lumineuse si aucune image complexe n'est affichée. L'organe d'affichage 7 est placé derrière la dalle 5, choisie transparente afin que l'utilisateur puisse voir ledit organe d'affichage 7 à travers la dalle 5. Si le module d'interface 1 ne comporte pas de fonctionnalités tactiles, la dalle 5 désigne la couche la plus haute attribuée à l'organe d'affichage 7 sous-jacent, par exemple une plaque de verre ou polycarbonate jouant un rôle protecteur. The transparent panel 5 is here a touch screen, for example capacitive or resistive, and is affixed to the upper surface of the display screen 7, which may be for example a liquid crystal display, organic diode OLED or plasma . The display member 7 may alternatively be a light box, a light guide or a diffusing screen placed above a light source if no complex image is displayed. The display member 7 is placed behind the slab 5, chosen transparent so that the user can see said display member 7 through the slab 5. If the interface module 1 does not have any tactile features, the slab 5 denotes the highest layer assigned to the underlying display member 7, for example a glass plate or polycarbonate playing a protective role.
Le film 3 est par exemple un film plastique polarisant, souple et relativement étirable, à forte transparence. Le film 3 comporte sur certaines zones de sa surface inférieure de l'encre opaque 9, appliquée par sérigraphie, notamment au moyen de pochoirs et raclettes. Cette encre opaque 9 est typiquement de l'encre noire, et sert à délimiter la surface E de l'écran final ou du symbole désiré par détourage de l'organe d'affichage 7 disposé en dessous. The film 3 is for example a polarizing plastic film, flexible and relatively stretchable, high transparency. The film 3 has on certain areas of its lower surface opaque ink 9, applied by screen printing, in particular by means of stencils and squeegees. This opaque ink 9 is typically black ink, and serves to delimit the surface E of the final screen or the desired symbol by trimming the display member 7 disposed below.
Pour appliquer l'encre 9, le film 3 est d'abord mis face inférieure vers le haut dans le référentiel usuel (terrestre), sérigraphié et ensuite retourné avant lamination. In order to apply the ink 9, the film 3 is first put face down in the usual (terrestrial) reference frame, screen printed and then returned before lamination.
Les couches représentées en figure 1 ne sont pas montrées à l'échelle. En particulier, le film 3 est d'une épaisseur de quelques centaines de microns à quelques millimètres, tandis que l'épaisseur des couches d'encre 9 est de l'ordre de cinq à cinquante microns. II est possible, comme montré en figure 1 , de sérigraphier également de l'encre translucide 11, par exemple gris fumé ou colorée, dans les portions laissées sans encre opaque 9 pour modifier le rendu esthétique final. Afin de ne pas laisser d'espace entre l'encre noire et la deuxième encre translucide généralement dédiée à l'affichage des symboles, il est préférable de faire chevaucher les encres noires et translucides comme représenté à la figure 1. Ce chevauchement créé une surépaisseur des encres. The layers shown in Figure 1 are not shown to scale. In particular, the film 3 is of a thickness of a few hundred microns to a few millimeters, while the thickness of the ink layers 9 is of the order of five to fifty microns. It is possible, as shown in FIG. 1, to screen also translucent ink 11, for example smoked or colored gray, in the portions left without opaque ink 9 to modify the final aesthetic rendering. In order not to leave space between the black ink and the second translucent ink generally dedicated to the display of symbols, it is preferable to overlap the black and translucent inks as shown in Figure 1. This overlap creates an extra thickness of the inks.
Le film 3 portant les couches d'encre 9, 11 sérigraphiées est ensuite appliqué par laminage sur la dalle 5, après un dépôt de colle C entre la dalle 5 et les couches d'encre 9, 11 sérigraphiées, par exemple par application de colle C sur la surface supérieure de ladite dalle 5. Bien sûr, il est possible alternativement ou en parallèle d'enduire de colle C la surface inférieure du film 3 portant les couches d'encre 9, 11 sérigraphiées. The film 3 carrying the ink-screened layers 9, 11 is then applied by rolling on the slab 5, after a glue deposit C between the slab 5 and the ink-printed layers 9, 11, for example by applying glue C of course on the upper surface of said slab 5. Of course, it is possible alternatively or in parallel to coat with glue C the lower surface of the film 3 carrying the ink layers 9, 11 screen printed.
Pour supprimer les dernières bulles d'air éventuelles, la dalle 5 portant le film 3 est ensuite placée sous vide et laissée à dégazer dans une étape supplémentaire et qui s'ensuit, par exemple dans une chambre à vide. To remove the last possible air bubbles, the slab 5 carrying the film 3 is then placed under vacuum and allowed to degass in an additional step and which follows, for example in a vacuum chamber.
Le module d'interface 1 ainsi obtenu ne possède pas de film découpant la surface d'écran ou de symbole E. Ladite surface E est détourée par l'encre opaque 9 sérigraphiée en couche fine. Cette absence de film cadre permet de réduire d'autant l'épaisseur finale du module 1. The interface module 1 thus obtained does not have a film that cuts off the screen or symbol surface E. Said surface E is cut off by the opaque ink 9 screen-printed in a thin layer. This lack of frame film makes it possible to reduce the final thickness of the module 1 by the same amount.
Le fait que l'encre 9, 11 est sérigraphiée permet en outre d'obtenir le cadre détourant la surface E dans un procédé simplifié et potentiellement moins coûteux. The fact that the ink 9, 11 is screen printed also makes it possible to obtain the frame that cuts the surface E in a simplified and potentially less expensive process.
Le film 3 est sérigraphié de deux couches d'encre, opaque 9 et translucide 11. Toutefois, la sérigraphie ne permet pas de limiter de manière très précise l'étendue des couches sérigraphiées. Pour cette raison, lors de la sérigraphie des couches 9, 11 il est avantageux de faire se recouvrir légèrement voire complètement lesdites couches 9, 11 au moins au niveau de leurs bords communs.  The film 3 is screen printed with two layers of ink, opaque 9 and translucent 11. However, the screen printing does not make it possible to limit in a very precise manner the extent of the screen-printed layers. For this reason, during the screen printing of the layers 9, 11 it is advantageous to overlap slightly or completely said layers 9, 11 at least at their common edges.
La figure 2 montre plus en détails un module d'interface 1 obtenu avec les étapes précédemment décrites, présentant un léger défaut, appelé retassures. La présence de zones sans encre 9, 11, ou bien la présence de chevauchement des différentes couches d'encre 9 et 11 à leurs bords entraîne des différences d'épaisseur du module 1 obtenu. Ces différences d'épaisseur sont connues sous le nom de retassures. Figure 2 shows in more detail an interface module 1 obtained with the previously described steps, having a slight defect, called sinkholes. The presence of ink-free zones 9, 11, or the presence of overlapping of the different ink layers 9 and 11 at their edges causes differences in the thickness of the module 1 obtained. These differences in thickness are known as blowholes.
La figure 2 montre un module d'interface 1 dans lequel le film 3 porte deux couches d'encre 9, 11 respectivement opaque et translucide. Ces deux couches d'encre 9, 11 sérigraphiées l'une après l'autre, se chevauchent au niveau de leurs bords communs 13. Après laminage et dégazage, ces chevauchements des bords 13 entraînent la formation des bosses 15 qui forment les retassures. Celles-ci sont indésirables en ce qu'elles altèrent le rendu esthétique du module d'interface 1 , notamment par des reflets et figures d'interférences. FIG. 2 shows an interface module 1 in which the film 3 carries two layers of ink 9, 11 respectively opaque and translucent. These two ink layers 9, 11 serigraphed one after the other, overlap at their common edges 13. After rolling and degassing, these overlaps of the edges 13 cause the formation of the bumps 15 which form the sinkers. These are undesirable in that they affect the aesthetic rendering of the interface module 1, in particular by reflections and interference patterns.
La figure 3 montre un module d'interface 1 analogue à celui de la figure 2, mais dans lequel le film 3 porte en outre une couche de vernis de remplissage 17. Cette couche de remplissage 17 est intercalée entre les couches d'encre 9, 11 et la surface sur laquelle est déposée la colle C de la dalle 5. FIG. 3 shows an interface module 1 similar to that of FIG. 2, but in which the film 3 also bears a layer of filling varnish 17. This filling layer 17 is interposed between the ink layers 9, 11 and the surface on which the adhesive C of the slab 5 is deposited.
La couche de remplissage 17 est composée d'un vernis, choisi pour avoir une faible viscosité et/ou une forte tension superficielle avec l'encre 9, 11 et/ou le matériau porteur du film 3, de sorte à former un mouillage complet ou presque complet sur les couches d'encre sérigraphiées 9, 11. De la sorte, le vernis recouvre toutes les anfractuosités et bosses éventuelles, ce qui conduit à la formation d'un film ayant une surface plane, en évitant l'inclusion de bulles d'air. The filling layer 17 is composed of a varnish chosen to have a low viscosity and / or a high surface tension with the ink 9, 11 and / or the material carrying the film 3, so as to form a complete wetting or almost complete on the silkscreened ink layers 9, 11. In this way, the varnish covers all crevices and possible bumps, which leads to the formation of a film having a flat surface, avoiding the inclusion of bubbles. 'air.
On prendra par exemple des fluides d'une viscosité de l'ordre de quelques dixièmes de poises (quelques 10 cP) au maximum, en particulier des résines époxyde ou polyéthyléniques avec les solvants et catalyseurs adaptés. Le volume utilisé est choisi de sorte que l'épaisseur finale de la couche de remplissage 17 est de l'ordre d'une à deux couches de sérigraphie, soit quelques dizaines de microns typiquement, de l'ordre de cinq à cinquante en particulier. Le vernis une fois appliqué uniformément est durci par traitement au rayonnement ultraviolet. Dès lors il s'est formé une couche de remplissage 17 qui comble les creux et couvre les bosses. Le film 3 avec encres sérigraphiées 9,11 et couche de vernis 17 ainsi obtenu est alors laminé sans que des retassures ne se forment. La figure 4 reprend dans un diagramme en blocs les différentes étapes du procédé 100 de fabrication d'écran de module d'interface. For example, fluids with a viscosity of the order of a few tenths of poise (some 10 cP), especially epoxy or polyethylene resins with the appropriate solvents and catalysts, will be used. The volume used is chosen so that the final thickness of the filling layer 17 is of the order of one to two screen printing layers, ie a few tens of microns typically, of the order of five to fifty in particular. The varnish once applied uniformly is cured by ultraviolet radiation treatment. Since then it has formed a filling layer 17 which fills the hollows and covers the bumps. The film 3 with screen-printed inks 9, 11 and varnish layer 17 thus obtained is then rolled without shrinkage being formed. FIG. 4 shows in a block diagram the different steps of the interface module display manufacturing method 100.
Dans la première étape 101, les encres opaque 9 et translucide 11 sont sérigraphiées sur la surface du film 3 destinée à devenir la surface inférieure de celui-ci pour délimiter des cadres ou symboles E. In the first step 101, the opaque and translucent inks 11 are serigraphed on the surface of the film 3 intended to become the lower surface thereof to delimit frames or symbols E.
Dans l'étape suivante 103, la couche de remplissage 17 en vernis durcissant aux UV est appliquée sur les couches d'encre sérigraphiées 9, 11, et durcie par irradiation ultraviolette. In the next step 103, the UV-curing varnish filler layer 17 is applied to the screen-printed ink layers 9, 11, and cured by ultraviolet irradiation.
Dans la troisième étape 105, de la colle C est déposée entre le film 3 côté encre sérigraphiée 9, 11 et la dalle 5 du module d'interface 1, et le film 3 portant les couches d'encre 9, 11 sérigraphiées est collé et laminé sur la dalle 5 du module d'interface. In the third step 105, glue C is deposited between the screen-printed ink film 3, 9 and 11 and the slab 5 of the interface module 1, and the film 3 carrying the screen-printed ink layers 9, 11 is glued and laminated on the slab 5 of the interface module.
Cette colle C peut être un film de colle type « double-face », pris entre deux couches de protection. Dans le cadre de l'utilisation présente, une des couches de protection peut être enlevée et la colle C laminée dans un premier temps sur le film de film de protection 3 portant les couches d'encre 9, 11 sérigraphiées. Dans un deuxième temps la seconde couche de protection est ensuite retirée et le film 3 portant les couches d'encre 9, 11 sérigraphiées et la colle C est laminé sur la dalle 5. This adhesive C may be a "double-sided" type adhesive film, sandwiched between two protective layers. In the context of the present use, one of the protective layers can be removed and the adhesive C laminated at first on the protective film film 3 carrying the ink layers 9, 11 screen printed. In a second step, the second protective layer is then removed and the film 3 carrying the ink layers 9, 11 screen-printed and the adhesive C is laminated on the slab 5.
Enfin durant l'étape 107 le film 3 portant les couches d'encre 9, 11 sérigraphiées collé sur la dalle 5 est placé sous vide pour dégazer et évacuer ainsi les éventuelles bulles d'air emprisonnées lors d'une des étapes précédentes. Finally, during step 107 the film 3 carrying the ink layers 9, 11 silkscreened stuck on the slab 5 is placed under vacuum to degass and thus evacuate any air bubbles trapped in one of the preceding steps.
Le procédé selon l'invention permet d'utiliser le film 3 couramment utilisé comme support de sérigraphie d'encre opaque 9 formant le cadre E de l'écran 7 ou délimitant des symboles. The method according to the invention makes it possible to use the film 3 commonly used as an opaque ink screen printing medium 9 forming the frame E of the screen 7 or delimiting symbols.
De ce fait, le procédé rend potentiellement moins épais et moins coûteux le module d'interface 1 produit. As a result, the method makes the interface module 1 produced potentially less thick and less expensive.
