Embodiment Construction

[0024] In the following parts of the specification, similar or identical components may be designated with the same reference signs.

[0025] in figure 1 with 2 Shown therein is a display device 10 provided to be housed in a passenger compartment of a motor vehicle (not shown). The display device 10 includes a housing 12 in which a display 14 is arranged.

[0026] In the following part of the description, the longitudinal direction A1 from front to back will be used, which corresponds to the direction perpendicular to the display 14 and corresponds to figure 2 The top-to-bottom direction seen in, but not limited to this.

[0027] The display 14 here has the shape of a substantially rectangular display block, which is arranged in the housing 12 opposite to and behind the display window 18 defined by the outer edge 20 in the front surface 22 of the housing 12. The display 14 is composed of, for example, a liquid crystal or light emitting diode display. The display 14 is here mounte...

Abstract

The invention relates to a display device (10) comprising a casing (12) containing a display screen (14) arranged facing a display window (18) defined by a peripheral edge (20). The device is characterised in that the casing (12) is provided with at least one light guide (32, 34) associated with at least one light source (36, 38), said light guide (32, 34) comprising: a first portion (40) which is arranged outside the peripheral edge (20) and which produces a side illumination beam (F1) outside the peripheral edge (20); and a second portion (42) which extends from the first portion (40), facing the display window (18), and which produces an auxiliary illumination beam (F2) in the display window (18).

Description

Technical field [0001] The present invention relates to a display device, and more particularly, to a display device provided to be provided in a passenger compartment of a motor vehicle. Background technique [0002] The present invention more specifically relates to a display device that includes a housing in which a display is housed and includes control buttons (such as those provided on the dashboard of a motor vehicle). The display is, for example, a rectangular liquid crystal display. An example of a display device is disclosed in the document DE102008048448A1. The size of the display (specifically its diagonal length) has a significant impact on the cost of the display device. The longer the diagonal, the higher the cost of the display device. [0003] The present invention aims to propose a solution that makes it possible to expand the display area while minimizing the size of the display. The invention also aims to economically improve the ergonomics of the display de...
