Display device for a vehicle

Abstract

The display device (12) for a vehicle is provided with a display (18) having a display surface (20) on a front side and having a rear side facing away from the latter and a cover screen (14) arranged in front of the display surface (20). Furthermore, the display device (12) has a decorative frame (16) which is connected to the edge of the cover screen (14) and protrudes on all sides over the edge of the display (18), and a rear-side housing shell (17) which has a rear wall (36) with an edge web (38) rising from the latter. The rear wall (36) of the housing shell (17) is arranged at a distance from the rear side of the display (18), wherein the edge web (38) of the housing shell (17) is connected to the decorative frame (16) by means of an adhesive.

Claims

1. A display device for a vehicle, comprising: a display with a display surface on a front side and with a rear side opposite thereto, a cover screen arranged in front of the display surface, a decorative frame which is connected to an edge of the cover screen and protrudes on all sides over an edge of the display, and a rear housing shell which has a rear wall with an edge web protruding from the latter, the rear wall of the housing shell being arranged at a distance from the rear side of the display and the edge web of the housing shell is connected to the decorative frame by means of an adhesive, wherein the decorative frame comprises a connecting section extending circumferentially around the cover screen and having an adhesive application surface for the adhesive connecting the edge web of the housing shell to the decorative frame on the cover screen of the display.

2. The display device according to claim 1, wherein the housing shell comprises a mounting part for mounting the housing shell in a vehicle for a self-supporting arrangement of the display device at and/or on and/or in the vehicle instrument panel.

3. The display device according to claim 1, wherein the adhesive connecting the edge web of the housing shell to the decorative frame on the cover screen of the display is designed as a strip-shaped adhesive material bed on the decorative frame, into which the edge web of the housing shell is immersed at its end averted from the rear wall of the housing shell.

4. The display device according to claim 3, wherein the edge web of the housing shell is immersed into the adhesive material bed at its end averted from the rear wall of the housing shell while maintaining a distance from the decorative frame as viewed in extension of the edge web.

5. The display device according to claim 1, wherein the display is connected at its display surface to the cover screen by means of a transparent adhesive layer.

6. The display device according to claim 1, wherein the display or the cover screen comprises a touch panel.

Description

(1) The invention will be explained hereinafter with reference to an embodiment and to the drawings. In detail, the Figures show:

(2) FIG. 1 a view of the instrument panel of a vehicle with a display device arranged standing upright on the instrument panel, and

(3) FIG. 2 a section through the display device along II-II in FIG. 1 to clarify the structure of the display device.

(4) FIG. 1 illustrates a view of the instrument panel 10 in the interior of a vehicle. A self-supporting display device 12, which in the present embodiment is designed as a touch screen, is situated on the instrument panel 10. At the front, the display device 12 has a cover screen 14 with a circumferential frame 16. Rearward of the cover screen 14, a housing shell 17 is located which closes the display device 12 to the rear and comprises a mounting part 19 for self-supported mounting on the instrument panel 10 (see FIG. 2).

(5) The actual display 18 with the display surface 20 is situated behind the cover screen 14. Between the cover screen 14 and the display 18, typically a touch panel 22 is located which is connected to the cover screen 14 by means of a transparent adhesive (not illustrated) and to which the display surface 20 of the display 18 is bonded by means of a transparent adhesive layer 24 (optical bonding). Usually, a backlighting unit 26 with a diffusor (not illustrated) is located behind the display 18.

(6) The decorative frame 16 is connected to the cover screen 14 e.g. by adhesion, the adhesive being illustrated at 28. The decorative frame 16 may, however, also be integrally formed as a single piece with the cover screen 14. For example, the decorative screen 16 has an inward protruding connecting section 30 as a kind of inner flange on which the cover screen 14 rests bonded by means of the adhesive 28. On the lower side of the connecting section 30 averted from the adhesive, an adhesive application surface 32 is provided on which a strand- or strip-shaped adhesive material bed 34 is applied.

(7) The housing shell 17 has a rear wall 36 and a circumferential edge web 38 protruding therefrom, the free end 40 thereof being immersed into the adhesive material bed 34, namely, in this embodiment, with a distance to the adhesive application surface 32 of the connecting section 30 of the decorative frame 16.

(8) In the bonded state of the housing shell 17 and the decorative frame 16, the rear 40 of the display 18 is spaced from the rear wall 36 of the housing shell 17.

(9) For mounting the display device 12, the housing shell 17 is set, for example, on the display 18 pre-assembled to the cover screen 14 with the decorative frame 16. At this point, the display 18 is connected to the cover screen 14. The decorative frame 16 of the cover screen or of the display device 12 is also already provided on the cover screen 14. Using a positioning device, the housing shell 17 is then slipped over the display 18 from behind in such a manner that the free end 40 of the edge web 38 is pressed into the not yet cured adhesive material bed 34. Here, care is taken to keep the rear wall 36 of the housing shell 17 spaced from the rear 42 of the display 18. Due to the fact that the edge web 38 and the connecting section 30 of the decorative frame 16 are not in contact, possible manufacturing tolerances of the two partial components connected according to the above described method can be compensated for. Moreover, it is possible to adjust the design gap between the decorative frame 16 and the housing shell 17 accordingly.
