Description

Technical Field

[0001] The invention relates to a display assembly formed from a transparent cover plate and a pixel matrix display arranged below the cover plate from the perspective of an observer, which is used in particular in a motor vehicle, for example in the outer region of a motor vehicle body. Background Art

[0002] Pixel matrix displays arranged below a transparent cover plate typically face the following problem: the display surface of the pixel matrix display should be arranged as close to the display surface as possible to avoid reflections at the interface. For example, an air layer between the cover plate and the display surface should be avoided because the interface from an optically denser medium to an optically thinner medium, and vice versa, each causes reflections that affect the view from the operator's perspective. For this reason, the display surface is typically bonded to the cover plate via a layer, such as an adhesive layer, which has the same or approximately the same optical refractive index as the material of the cover plate. This loses the mechanical advantage of the air layer, namely that the air layer at least substantially decouples the pixel matrix display from mechanical effects, since the adhesive generally cures in an impact-resistant manner. Furthermore, since bonding is usually performed using a liquid adhesive, this often presents the following difficulty: loss of liquid adhesive leads to uneven formation of the adhesive layer. When the display surface of the pixel matrix display is bonded directly to the cover plate, there is a risk that the pixel matrix display will be subjected to a force curve and thus irreversibly damaged if a force is applied to the cover plate. Summary of the Invention

[0003] Against this background, there is a need for a display assembly of the above-mentioned kind, which has the advantage of a reflection-free optical bond between the cover plate and the display surface of the associated pixel matrix display, but at the same time provides a reliable fastening by means of a uniform adhesive layer, and on the other hand the pixel matrix display is not exposed to an increased risk of mechanical damage.

[0004] Correspondingly, a corresponding assembly method is required, with which such a display assembly can be realized. This object is achieved by the assembly method according to claim 1 or the display assembly according to the parallel independent claim. Likewise advantageous uses are the subject matter of the use claims. Advantageous design solutions are respectively the subject matter of the dependent claims. It should be noted that the features detailed individually in the claims can be combined with each other in any technically meaningful manner and present other design solutions of the invention. The description, in particular in conjunction with the drawings, additionally characterizes and explains the invention in detail.

[0005] The present invention relates to a method for assembling a display assembly, wherein in an arrangement step, a support frame and an at least partially transparent cover plate are arranged so that the support frame abuts the cover plate, thereby forming an intermediate space defining a cavity, which is limited by the support frame and the cover plate. At the same time, the cover plate and the support frame form a groove for receiving a pixel matrix display having a display surface. The intermediate space forming the cavity preferably extends around the groove and more preferably completely surrounds the groove. For example, the support frame has a central hole, so that the support frame surrounding the central hole defines the inner wall of the groove facing the central hole. For example, the bottom plate of the groove is formed by the cover plate. The support frame is preferably formed from a fiber-reinforced plastic, more preferably from a fiber-reinforced thermoplastic.

[0006] According to the present invention, the support frame is designed to fix the display assembly to a support structure, in particular a motor vehicle body. For example, the support frame has a snap-fit ​​element or a device for screw fastening, such as a central hole or a threaded hole.

[0007] In a subsequent step, a thermoplastic elastomer is introduced into the cavity defined by the intermediate space, so as to fill, preferably completely fill, the cavity with the thermoplastic elastomer. By subsequently solidifying the thermoplastic elastomer, the support frame is fixed to the cover plate by a material bond, while the residual elasticity that remains long after solidification provides a long-term, robust connection between the cover plate and the support frame, which has a sealing effect.

[0008] In a subsequent step, the groove is then filled with a transparently curing liquid adhesive, thereby forming an adhesive layer, wherein the sealing effect of the thermoplastic elastomer in the hollow space ensures that the loss of the liquid adhesive is prevented. The liquid adhesive is preferably an acrylate-based liquid adhesive or a two-component silicone adhesive.

[0009] When filling the trough with the liquid adhesive, the liquid adhesive preferably wets the support frame, in particular the inner wall of the trough formed thereby, preferably the inner wall of the trough is wetted on all sides by the liquid adhesive. For example, the amount of liquid adhesive introduced is selected such that when the liquid adhesive is distributed (in certain cases autonomously) in the trough, a substantially uniform filling level is achieved in the trough, with the inner wall of the trough being wetted on all sides.

[0010] Subsequently, the step of introducing the pixel matrix display into the groove is carried out, wherein the display surface of the pixel matrix display faces the adhesive layer and is wetted by the liquid adhesive of the adhesive layer over its entire surface. In the case of using a polar liquid adhesive, this wetting can be assisted, for example, in an electrostatic manner. In a subsequent step, the adhesive is cured. This should be understood as chemically and / or physically curing the adhesive, such as increasing the degree of crosslinking of the adhesive. The adhesive can, for example, be a radiation-curing adhesive, such as a UV-curing adhesive, so that the adhesive is cured by means of corresponding radiation passing through the cover plate.

[0011] By curing, it is achieved that the pixel matrix display is fixed to the cover plate on the display surface, while due to the transparency of the cover plate and the layer located therebetween (such as the adhesive layer), the display surface remains visible through the cover plate and the adhesive layer. Preferably, the pixel matrix display is fixed only on the display surface, that is to say it is thereby fixed to the cover plate "in a suspended manner". The present invention is not restricted in terms of the pixel matrix display. For example, it can be a so-called touch screen, that is, a combination of a pixel matrix display and a spatially resolved touch sensor, such as a capacitive spatially resolved touch sensor. The pixel matrix display is, for example, a liquid crystal display of a twisted nematic structure, a super twisted nematic structure, a double super twisted nematic structure, a triple super twisted nematic structure, a vertically aligned structure or a plane switching structure. The display surface is respectively a component of the outer surface of the pixel matrix display and is, for example, defined by the outermost layer of the pixel matrix display, which is usually implemented in a layer structure. Depending on the construction method, the display surface is, for example, a transparent cover layer or a transparent protective layer carrying electrodes. Alternatively, a transparent electrode structure provided for spatially resolved capacitive touch detection can also be a component of the cover plate and applied, for example, on the surface facing the pixel matrix display.

[0012] By using the support frame to secure the display assembly to the support structure, the pixel matrix display is positioned outside the force flux acting on the cover plate. Mechanical clamping of the pixel matrix display between the cover plate and the support structure (e.g., the body of a motor vehicle) is prevented. This substantially minimizes the risk of damage to the pixel matrix display. This method is particularly suitable when, according to a preferred embodiment, the support frame is specifically used to secure the display assembly to the support structure.

[0013] According to a preferred embodiment of the method of the present invention, in a step after curing, a housing covering the pixel matrix display is fixed to the support frame, i.e., contact between the pixel matrix display and the housing is avoided. The housing is used to mechanically protect the pixel matrix display. To prevent the introduction of foreign objects or fluids, according to a preferred design, a seal is provided between the housing and the support frame. The seal is, for example, made of rubber, natural rubber, or a thermoplastic elastomer.

[0014] In order to simplify assembly, according to a preferred variant of the assembly method, the housing is fixed to the support frame by snapping together engaging pieces.

[0015] According to a preferred variant of the method according to the invention, at least one further decorative element and / or fastening element is provided, which is used, for example, to fasten further components to the cover plate or also to fasten the display assembly to a supporting structure, by means of a layer formed by the thermoplastic elastomer during injection and solidification to the cover plate outside the groove.

[0016] The cover plate is, for example, a layer formed from a transparent plastic, such as a thermoplastic. Preferably, the cover plate comprises a glass material. Still more preferably, the cover plate is single-layer safety glass, that is, tempered glass according to EN 12150-1, or composite glass. The latter is a composite of two or more flat glass panes connected by a plastic foil (typically a relatively tear-resistant and viscoplastic foil).

[0017] According to a preferred embodiment of the method, the support frame is made of plastic, such as thermoplastic, preferably fiber-reinforced plastic. Preferably, the support frame is produced in a preceding step using an injection molding process, preferably two-component injection molding. For example, the support frame and the seal are extruded in a common two-component injection molding step, thereby creating a material-bonded connection between the two.

[0018] In a preferred embodiment of the method according to the invention, the support frame is fixed to the motor vehicle body in a final step, wherein in the fixed position the pixel matrix display has no contact with the motor vehicle body.

[0019] The present invention also relates to a display assembly having an at least partially transparent cover plate. The cover plate is, for example, a layer formed from a transparent plastic, such as a thermoplastic. The cover plate preferably comprises a glass material. Still more preferably, the cover plate is single-layer safety glass, that is, tempered glass according to EN 12150-1, or composite glass. The latter is a composite of two or more flat glass sheets connected by a plastic foil, typically a relatively tear-resistant and viscoplastic foil.

[0020] The display assembly according to the present invention further comprises a support frame for securing the display assembly to a support structure, in particular a motor vehicle body. The support frame is preferably formed from a fiber-reinforced plastic, more preferably a fiber-reinforced thermoplastic. According to the present invention, the support frame is designed to secure the display assembly to a support structure, in particular a motor vehicle body. For example, the support frame comprises snap-fit ​​elements or means for screw fastening, such as a central hole or threaded holes.

[0021] The display assembly of the present invention also includes a pixel matrix display with a display surface. The present invention is not limited to the pixel matrix display. For example, it can be a so-called touch screen, that is, a combination of a pixel matrix display and a spatially resolved touch sensor, such as a capacitive spatially resolved touch sensor. The pixel matrix display is, for example, a liquid crystal display with a twisted nematic structure, a super twisted nematic structure, a double super twisted nematic structure, a triple super twisted nematic structure, a vertically aligned structure, or an in-plane switching structure. The display surface is a component of the outer surface of the pixel matrix display and is defined, for example, by the outermost layer of the pixel matrix display, which is usually implemented in a layer structure. Depending on the construction method, the display surface is, for example, a transparent cover layer or a transparent protective layer carrying electrodes. Alternatively, a transparent electrode structure configured for spatially resolved capacitive touch detection can also be a component of the cover plate and, for example, applied to the surface facing the pixel matrix display.

[0022] The display assembly of the present invention may optionally have a housing.

[0023] According to the present invention, the support frame is arranged adjacent to the cover plate. This forms an intermediate space bounded by the support frame and the cover plate, which is filled, preferably completely filled, with a thermoplastic elastomer to secure the support frame to the cover plate. Furthermore, the cover plate and the support frame form a groove for receiving the pixel matrix display. For example, the support frame has a central hole, so that the support frame, which surrounds the central hole, defines the inner wall of the groove facing the central hole. For example, the bottom plate of the groove is formed by the cover plate. Preferably, the intermediate space extends around the groove, and more preferably, the intermediate space completely surrounds the groove.

[0024] According to the invention, a transparent adhesive layer is formed in the groove between the display surface and the cover plate to secure the pixel matrix display to the cover plate, wherein the display surface is visible through the cover plate and the adhesive layer. Preferably, the pixel matrix display is fastened only on its display surface and is thus fixed to the cover plate in a suspended manner. The optional housing, if present, is fixed to the support frame in such a way as to cover the pixel matrix display.

[0025] By using the support frame to secure the display assembly to the support structure, the pixel matrix display is positioned outside the force flux acting on the cover plate. Mechanical clamping of the pixel matrix display between the cover plate and the support structure (e.g., the body of a motor vehicle) is prevented. The risk of damage to the pixel matrix display is minimized. This method is particularly suitable when, according to a preferred design, the support frame is specifically designed for securing to the support structure.

[0026] In a preferred embodiment of the display assembly, a sealing member is provided between the housing and the supporting frame, wherein the sealing member is made of, for example, rubber material, natural rubber material or thermoplastic elastomer.

[0027] According to a preferred embodiment of the display assembly according to the invention, at least one further decorative element and / or fastening element is further provided, which is arranged outside the groove and is fixed to the cover plate by means of a layer formed of thermoplastic material.

[0028] For example, in addition to the support frame, this further decorative element and / or fastening element serves to fasten the display assembly to a support structure, in particular a motor vehicle body, or to attach another component to the cover.

[0029] It is preferably provided that the adhesive layer adjoins, preferably on all sides, the support frame, more preferably the surface forming the inner wall of the groove.

[0030] According to a preferred variant of the display assembly of the present invention comprising the optional housing, the optional housing is fixed to the support frame by means of snap-fit ​​elements.

[0031] The invention also relates to the advantageous use of the display assembly of one of the described embodiments on a motor vehicle, in particular in an outer area of ​​a motor vehicle body. Preferably, the display assembly is arranged near a body opening, for example near a door, such as in a B-pillar of a motor vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 An embodiment of a display assembly 1 according to the invention is shown. The display assembly has a cover plate 2 that is at least partially transparent. The cover plate 2 is single-layer safety glass, that is to say tempered glass or composite glass according to EN 12150-1. The latter is a composite of two or more flat glass plates connected by a plastic foil. The cover plate 2 is mounted in the B-pillar area of ​​a motor vehicle (not shown), wherein the surface 16 of the cover plate 2 defines the outside of the motor vehicle and the surface 14 of the cover plate 2 faces the vehicle body or the vehicle interior. The display assembly 1 according to the invention also has a support frame 5, which is used to fix the display assembly 1 to the vehicle body. The support frame 5 is made of fiber-reinforced thermoplastic and has means for fixing to the vehicle body, such as snap-fit ​​parts or means for screw fastening, such as a central hole or threaded hole, which are not shown in detail.

[0039] The display assembly 1 according to the present invention also includes a pixel matrix display 3 with a display surface 4. The present invention is not restricted by the imaging technology used for the pixel matrix display 3. The display surface 4 is a component of the outer surface of the pixel matrix display 3 and is defined, for example, by the outermost layer of the pixel matrix display 3, which is typically implemented in a layer structure. A transparent electrode structure 11, which is provided for spatially resolved capacitive touch detection, is a component of the cover plate 2 and is applied as a coating on a foil substrate to a surface 14 of the innermost glass layer of the cover plate 2, which faces the vehicle, and which faces the pixel matrix display 3.

[0040] The display assembly 1 according to the present invention further comprises a housing 8, which is formed to cover the pixel matrix display 3 and the evaluation electronics arranged on the circuit board 10 and is fixed to the support frame 5 via a seal 9 and latches (not shown). To this end, a recess 5a is formed in the support frame 5, into which the housing 8 engages. The support frame 5 itself is arranged adjacent to the cover plate 2, i.e., adjacent to the surface 14 of the cover plate 2 facing the pixel matrix display 3. Here, an intermediate space 6 is formed, bounded by the support frame 5 and the cover plate 2, which is filled, preferably completely filled, with a thermoplastic elastomer to secure the support frame 5 to the cover plate 2. The cover plate 2 and the support frame 5 form a groove 15 for receiving the pixel matrix display 3. The support frame 5 thus has a central hole, wherein the support frame 5, which surrounds the central hole, defines the inner wall 15b of the groove 15 facing the central hole. The bottom 15a of the groove 15 is formed by the cover plate 2. The intermediate space 6 filled with thermoplastic elastomer extends around the groove 15 so that the groove is completely surrounded by the intermediate space 6 and acts as a seal in order to prevent fluid from being introduced into the groove 15 and the pixel matrix display 3 located therein.

[0041] A transparent adhesive layer 7 is formed in groove 15 between display surface 4 of pixel matrix display 3 and cover plate 2 to secure pixel matrix display 3 to cover plate 2 by adhesive bonding. Display surface 4 is visible through cover plate 2 and adhesive layer 7 (due to its optical transparency). Adhesive layer 7 extends over the entire surface of display surface 4 between opposing inner walls 15 b of groove 15. Pixel matrix display 3 is fastened only on its display surface 4 and is thus fixed to cover plate 2 in a suspended manner.

[0042] By using support frame 5 to secure display assembly 1 to a supporting structure (here, the vehicle body), it is ensured that pixel matrix display 3 is positioned outside the force flux when forces act on cover 2. Mechanical clamping of pixel matrix display 3 between cover and supporting structure (e.g., the vehicle body) is prevented. Damage to pixel matrix display 3 is thus largely eliminated.

[0043] In addition to the support frame 5, a further decorative and / or fastening element 12 is provided, which is arranged outside the groove 15 and is fixed to the cover plate 2 by means of a layer 13, which is also made of thermoplastic material. This decorative and / or fastening element 12 serves here to cover a gap at the B-pillar of the motor vehicle.

[0044] Will refer to Figures 2 to 5 One embodiment of the assembly method of the present invention is explained.

[0045] exist Figure 2In the arrangement step shown in FIG, the support frame 5 and the at least partially transparent cover plate 2 are arranged so that the support frame 5 abuts the cover plate 2, thereby forming an intermediate space 6 defined by the support frame 5 and the cover plate 2, the intermediate space predetermining a cavity. At the same time, the cover plate 2 and the support frame 5 formed of fiber-reinforced thermoplastic form a groove 15 for receiving the cover plate 2 in the intermediate space 6. Figure 2 1 . A pixel matrix display (not shown) is shown in FIG. The cavity-forming intermediate space 6 extends around the groove 15 and completely surrounds it. The support frame 5 has a central hole, so that the support frame 5 surrounding the central hole defines the inner wall 15b of the groove 15 facing the central hole, while the bottom 15a of the groove 15 is formed by the cover plate 2. The cover plate 2 is single-layer safety glass, that is, tempered glass or composite glass according to EN 12150-1. A transparent electrode structure 11, which is provided for spatially resolved capacitive touch detection, is an integral part of the cover plate 2 and is applied as a coating on a transparent foil substrate to the surface 14 of the glass layer of the cover plate 2 facing the pixel matrix display 3.

[0046] The support frame 5 is determined and designed for fixing the display assembly 1 on the motor vehicle body, in this case on the B-pillar of the motor vehicle body. Figure 2 The step of introducing the thermoplastic elastomer into the cavity defined by the intermediate space 6, already shown, is repeated in order to completely fill the cavity with the thermoplastic elastomer. Subsequent solidification of the thermoplastic elastomer secures the support frame 5 to the cover panel 2 via a materially bonded connection. The residual elasticity that persists even after solidification provides a long-term, robust connection between the cover panel 2 and the support frame 5, providing a seal. Simultaneously, a further decorative and / or fastening element 12 is secured to the cover panel, but outside the groove 15, by means of the thermoplastic elastomer. This decorative and / or fastening element 12 serves to cover a gap in the B-pillar of a motor vehicle.

[0047] exist Figure 3 In a subsequent step shown in FIG, the groove 15 is then filled with a transparent, curing liquid adhesive, thereby forming an adhesive layer 7, wherein the sealing effect of the thermoplastic elastomer in the intermediate space 6 ensures that the liquid adhesive is prevented from being lost. The liquid adhesive is, for example, an acrylate-based liquid adhesive or a two-component silicone adhesive.

[0048] Here, when filling the groove 15 with liquid adhesive, the liquid adhesive wets the support frame 5, i.e. the inner wall 15b of the groove 15 formed by the support frame, on all sides, because the amount of liquid adhesive introduced is selected so that a substantially uniform filling level is achieved in the groove 15 when the liquid adhesive is distributed in the groove 15, until the inner wall 15b of the groove 15 is wetted on all sides and a transparent adhesive layer 7 is formed.

[0049] Then proceed in Figure 4, the pixel matrix display 3 is introduced into the groove 15, wherein the display surface 4 faces the adhesive layer 7 and is wetted over the entire surface with the liquid adhesive of the adhesive layer 7. During the subsequent curing of the adhesive layer by chemical or physical crosslinking of the liquid adhesive, the pixel matrix display 3 is fixed to the cover plate 2 on the display surface 4, and the display surface 4 is visible through the cover plate 2 and the adhesive layer 7. In this case, the pixel matrix display 3 is fixed only on the display surface 4, that is, it is thus fixed to the cover plate 2 in a "hanging" manner.

[0050] By using support frame 5 to secure display assembly 1 to the vehicle body, pixel matrix display 3 is positioned outside the force flux acting on cover plate 2. Mechanical clamping of pixel matrix display 3 between cover plate 2 and the vehicle body is prevented. This largely eliminates damage to pixel matrix display 3.

[0051] After curing Figure 5 In the step shown in , the housing 8 is fixed to the support frame 5. The housing 8 covers the pixel matrix display 3 and the analysis electronics arranged on the circuit board 10. The housing 8 is fixed to the support frame 5 via a seal 9 and a not shown snap-in element. The seal 9 is a layer made of a thermoplastic elastomer, which is arranged on the side walls of the recess 5a of the support frame 5 and serves to prevent the introduction of foreign objects or fluids. In a two-component injection molding step, the seal 9 and the support frame 5 are produced in an extrusion step for molding, so that a material bonded connection is produced between the two. The housing 8 serves to mechanically protect the pixel matrix display 3 and the analysis electronics further located thereunder.
