Description
Technical Field
The present invention relates to a display device.
Background
DE 10329366B 4 discloses a structural element, in particular a display device with organic light-emitting diodes.
Disclosure of Invention
A display device is proposed, which comprises an illumination unit, a housing for the illumination unit, a liquid crystal panel, a support and a cover element, wherein the illumination unit is arranged in or at the housing. The housing with the lighting unit is arranged on a support, and the cover glass is arranged on the liquid crystal panel by means of an adhesive material. Furthermore, the liquid crystal panel is arranged on the housing by means of a flexible element in such a way that a closed region is formed between the liquid crystal panel and the lighting unit by means of the flexible element.
The display device can be arranged, for example, in an instrument cluster and/or in a dashboard, in particular of a vehicle. By means of the display device, information can be displayed for a vehicle occupant, for example a driver and/or a co-driver. For example, information about the vehicle state can be displayed. The vehicle mode can be displayed, for example, by means of a display device. The output information can be, for example, information about the vehicle state, such as speed, rotational speed display, fuel tank filling level and/or information about vehicle navigation and/or information about the entertainment system. The display device can also be referred to as a projection device.
The advantage of the invention is that a mechanical decoupling is formed between the liquid crystal panel and the illumination unit. Thereby, the force acting on the illumination unit is not transmitted to the liquid crystal panel, whereby for example disturbing effects like e.g. aliasing effects (Mura-Effekt) can be reduced. Thereby, especially a reliable functional performance of the liquid crystal panel can be ensured. It is preferable that the influence on the optical characteristics of the liquid crystal panel can be reduced. This enables the display device to reliably display the graphic representation, particularly for the observer.
Further, by the closed region, a sealed region between the liquid crystal panel and the illumination unit can be realized. Thereby, contamination between the liquid crystal panel and the lighting unit, like for example dust, particles or moisture, can be reduced or avoided, among other things. Thereby, the possibility of affecting the functional performance of the display device and thereby affecting its optical characteristics, in particular the image display of the liquid crystal panel, can be reduced or prevented. In other words, the area between the liquid crystal panel and the illumination unit is sealed from the ambient environment.
In an exemplary embodiment, the closed region can be formed between the flexible element, the liquid crystal panel, the lighting unit and the housing. By means of the closed region, contamination between the liquid crystal panel and the illumination unit can be reduced or avoided, whereby especially the optical properties of the display device and especially of the liquid crystal panel are not or hardly affected. This ensures, in particular, the functionality of the display device.
In one development, the flexible element can be designed as an elastically and/or plastically deformable flexible element. In an exemplary embodiment, the flexible element can be designed in particular as a foam and/or a membrane. Thereby, mechanical decoupling between the liquid crystal panel and the illumination unit can be achieved. Thereby, forces acting in particular on the lighting unit can be not or hardly transmitted to the liquid crystal panel. Accordingly, the influence on the optical characteristics of the liquid crystal panel can be kept small, and the display device can reliably display the graphic representation.
Furthermore, the flexible element can be arranged on the liquid crystal panel and/or the housing, in particular by means of a material-locking connection. For example, the flexible element can be arranged on the liquid crystal panel and/or the housing by means of an adhesive connection. In particular, a closed or sealed region between the liquid crystal panel and the illumination unit can thereby be ensured. Furthermore, the flexible element can be arranged in particular securely and/or reliably on the housing.
Advantageously, the liquid crystal panel and the lighting unit can be arranged adjacent to each other with their respective largest sides of the liquid crystal panel and the lighting unit. This ensures that the light beam emitted by the illumination unit is particularly efficiently radiated onto the liquid crystal panel. Thereby, the liquid crystal panel can be reliably illuminated from the back, in particular. Furthermore, the arrangement can be designed in a space-saving manner, which results in a saving of installation space.
In one development, the flexible element can be arranged circumferentially at the opening of the housing and/or circumferentially at the edge of the liquid crystal panel. In particular, this makes it possible to design the closed or sealed region between the liquid crystal panel and the illumination unit particularly optimally. In particular, dirt can thereby be prevented from penetrating into the closed region between the liquid crystal panel and the illumination unit, whereby in particular the optical properties of the liquid crystal panel and thus of the display device can be ensured. Thereby, the influence on the functionality and thus the optical properties of the liquid crystal panel and thus the display device can be reduced. Furthermore, the mechanical decoupling of the liquid crystal panel from the illumination unit can be configured particularly reliably.
In an advantageous embodiment, the cover element can be arranged in particular on the support. In particular, the cover element can thereby be held securely by means of the holder.
Furthermore, a method for producing a display device is proposed, which method has the following steps:
providing a lighting unit, a housing for the lighting unit, a liquid crystal panel, a support, a cover element and a flexible element,
arranging the lighting unit in or at a housing,
the cover glass is arranged on the liquid crystal panel by means of an adhesive material,
arranging the flexible element on the liquid crystal panel or the housing,
arranging the liquid crystal panel on the housing by means of a flexible element such that a closed area is constructed between the liquid crystal panel and the lighting unit by means of the flexible element,
the housing with the lighting unit is arranged on a support by means of a fixing element.
In particular, the closed or sealed region between the liquid crystal panel and the illumination unit can thereby be designed in such a way that contamination in the closed region can be reduced. This can reduce the possibility of affecting the optical characteristics of the display device and the functionality of the liquid crystal panel. Furthermore, the liquid crystal panel can be mechanically decoupled from the illumination unit, as a result of which mechanical forces from the illumination unit onto the liquid crystal panel, which may for example constitute disturbing effects, can be reduced or prevented, in particular.
In one development, the method can have a further step of providing the mounting element and a further step of arranging the mounting element on the liquid crystal panel and the carrier. By means of the assembly member, the liquid crystal panel can be stabilized with respect to the illumination unit when manufacturing or mounting the display device. Thereby, the liquid crystal panel can be arranged particularly safely and/or reliably on the housing by means of the flexible element. The liquid crystal panel and the lighting unit can preferably be held together by means of a mounting element when mounted. In one development, a plurality of mounting elements can be used.
In an advantageous embodiment, the method can have a further step of removing the mounting element after the display device has been mounted. Due to the removal of the fitting element, a flexible connection between the liquid crystal panel and the lighting unit can be achieved, in particular by means of a flexible element, whereby, in particular, little or no force is transmitted from the lighting unit to the liquid crystal panel. In particular, the optical properties of the display device can thereby be reliably ensured and thus are not or hardly adversely affected. As an alternative to the removal of the mounting element, the mounting element can in particular be designed so flexibly that no forces are transmitted from the lighting unit to the liquid crystal panel.
