    DISCLOSURE OF THE INVENTION Oils prior art invention comprises a display device comprising a glassmaking unit, a coverslip, and a support for supporting the silicon forming unit and the coverslip, the image forming unit being interposed between the coverslip and the support. The support is at least first connected to the first cover Bllderzeugungseinhsit and arranged on at least a second adhesive bond to the cover glass.
    Image forming units, for example displays such as liquid crystal displays and / or LCDs, have a high sensitivity with regard to pressure as well as the homogeneity of the display content. When Using a Blower Case In a vehicle such as an automobile or a two-wheeled vehicle, loads from external influences such as shocks or vibrations are high. By adhering both the south generating unit and the cover glass to a support, the image forming unit can be stored stress-relieved from the front and the back of the image forming unit, thereby reducing or eliminating one-sided loading on, for example, the front of the BHdsrzeugungseShelt. In this way, the longevity and the reading quality, in particular the contrast, of the image-forming unit are improved. Furthermore, the second adhesive bond between the cover glass and the carrier can be relieved by means of the first adhesive bond between the carrier and the image-forming web.
    Another advantage of using a first and a second adhesive bond is the increased stiffness and thus the improved Elgenfrequenzverhaiten the composite, By the use of two adhesive compounds harmful amplitudes in Reconsnzfail at low excitation frequencies can be reduced or avoided.
    Furthermore, the second adhesive bond between the coverslip and the carrier may include a sealing function in addition to the hoisting action. The second
    Adhesive bond thus seals and protects the bi-generation unit from external substances, for example water or solid particles such as dust. In a further advantageous embodiment, the bi-generation unit has a first surface and a second surface opposite the first surface. In this case, the second surface of the image-forming unit is advantageously connected to the carrier by means of the at least one first sliding connection. Thus, in particular, the at least one first adhesive joint is in contact with the second surface of the image-forming unit and with the carrier. In this way, it is possible to ensure that the bi-generation unit is connected to the carrier with low voltage, preferably via the rear side of the bi-generation unit, or is connected to the carrier. As a result, structural tolerances can be compensated and the longevity of the image-forming unit can be improved. Furthermore, the reading quality of the biological generating unit can be advantageously influenced, since loads due to external influences, such as shocks or vibrations, can be better absorbed or reduced.
    Advantageously, the cover glass has a first surface, wherein the first surface of the cover glass is arranged on the first surface of the bi-generation unit. The advantage of veneering a cover glass lies in the better readability of the image generation unit and in the protection of the image generation unit, for example from scratching the surface of the biosynthesis unit, the cover glass being designed, for example, as a protective glass made of real glass and / or plexiglass. By using a full-surface, transparent bonding (optical bonding) between dom cover glass and the Biiderzeugungseinheit multiple reflections at the 'air transitions can be reduced or avoided.
    Furthermore, the first surface of the cover glass is preferably connected by means of at least a second Kiebeverbindung with the carrier. The second splice connection thus contacts both the first surface of the coverslip and the support.
