Definitions

• the invention relates to a method for mounting a display module behind a window, in particular a window of a vehicle, the display module being designed to display a display visible from the outside of the window and comprising a plurality of display elements, each of which a tilting segment and one of the tilting segment have assigned light source. It also relates to a system of coordinated components designed for use in the method and to components of the system.
• the display modules to which the invention relates are arranged behind panes.
• the panes can be stationary, for example for passenger information, or mobile, for example in vehicles for public transport.
• the invention is described below without restricting generality with the aid of destination displays in buses.
• one or more display modules are arranged in a closed box, which on the visible side has its own pane that is independent of the vehicle and is fastened in the vehicle by means of special fastening devices connected to the body of the vehicle.
• the fastening housings for the display modules have a high weight, which can be approximately 60 kg in the case of front window displays, and access to the display modules difficult in the closed housing and a service is therefore complex. Furthermore, visibility is impaired due to the fact that the display is at a certain distance from the vehicle window and an additional window is interposed in the housing. To avoid reflections, the glasses are therefore sometimes anti-reflective.
• the display itself is realized by means of a backlit banner or by means of one or more display modules, each with a matrix comprising display elements comprising tilting segments.
• Each tilting segment comprises a pivoting disc which is colored light, for example yellow on one side and dark, for example black on the opposite side.
• the individual tilting segments can be brought individually into one or the other position, preferably by magnetic actuation by means of an electromagnetic control, so that the totality of the tilting segments can display numbers and letters composed of the light sides.
• An advantageous peculiarity can be that the tilting segments are bistable, ie that a control current is only required to fold the tilting segments and the orientation of the tilting segments is stable in both positions without a current flow being required.
• the tilting segments are illuminated by means of a common lighting device, for example a neon tube extending along the display module.
• Tilt segment displays are also known, each of which has a light source assigned to the tilt segment.
• the light source is preferably a light-emitting diode, but can also be implemented in another way, for example by means of optical fibers. There are various designs for the arrangement of the light source assigned to each tilting segment.
• the light source is arranged so that it faces the display side, i.e. the bright side of the tilting segment is illuminated.
• the light emitted by the light source cannot be seen, or at most only to a small extent, or at certain viewing angles, directly for the viewer who sees exclusively or essentially the light diffusely reflected from the display side.
• the light source can for example be arranged next to the tilting segment and illuminate it from the side. In special embodiments, however, the light source can also be arranged above the tilting segment and illuminate the display side.
• this first variant has several practical disadvantages. If the light source illuminates the tilt segment tet must be arranged in the space between the tilting segment and the inside of the disc. Since this requires a mechanical holder and an electrical feed and, if necessary, the emitted light must be covered by an aperture toward the viewer, in some embodiments it may be necessary to have a greater distance than is absolutely necessary to enable the tilting segment to be pivoted, to adhere to the inside of the pane. Such displays tend to be at a greater distance from the window.
• the reflections on the pane and in the pane which are often strongly curved in buses and are made of relatively strong material and in which the light can propagate through single and multiple reflections, lead to losses in intensity and contrast.
• the light source assigned to a tilting segment is arranged such that it emits the light directed towards the viewer.
• the light from the light source is therefore directly (not indirectly via the tilting segment) visible to the viewer, ie the viewer "looks into the light source".
• the light sources do not illuminate the tilt segments, but radiate (at least the main part of their emitted light) directly to the viewer. It must of course be taken into account that the light emission takes place over a certain angular range, so that the display can be recognized by viewers from different locations.
• the result is a double display matrix, namely that of the bright sides of the tilting segments and that of the switched-on light sources, which independently display the desired display.
• the double display matrix has the advantage that the human eye automatically and individually, depending on e.g. of visual acuity, which selects the best possible recognizable display. This facilitates and improves the reading of the displayed information, regardless of the prevailing lighting, time of day and night, weather conditions and other visual impairments.
• two or more light sources can each be assigned to a tilting segment, or vice versa
• two or more tilting segments each can be assigned to a light source, provided that it is practical and economically justifiable to design the display elements twice or more.
• Display elements with tilting segments which have a light source assigned to the tilting segment are described, for example, in documents EP 0401980 B1, EP 0463725 A2, EP 0556954 B1, EP 0731435 AI, US 3,942,274, US 4,243,978, US 4,531,318, US 5,005,305 and US 5,022,171.
• the invention is based on the object of creating the above-mentioned method for mounting display modules with tilting segment displays and a related system and suitable components by means of which the disadvantages of the prior art with regard to the assembly effort, the weight of the housing, the ease of servicing the display modules and the visibility of the display can be reduced or avoided.
• strips preferably run essentially horizontally and can accommodate one or more display modules arranged next to one another.
• the height of the display modules determines the required spacing of the profile strips.
• the display modules are designed to match the fastening elements, ie the display modules itself or module carrier profile strips or adapter elements attached to it, the display modules can be fitted to the fastening elements with a precise fit in terms of shape and / or arrangement.
• the system according to the invention is thus a combination of adhesive and connection techniques, the connection between the display module and the fastening element preferably being realized in a manner that is as easy as possible to assemble, directly or indirectly, by sliding, screwing, locking or the like.
• the assembly of the display modules does not require any structural changes to the vehicle body and no vehicle-specific necessities, such as, for example, housing fastenings connected to the body, so that installation is also possible at any time without
• the installation time of a destination display can be significantly reduced, for example from 150 minutes to 30 minutes, a weight saving of up to 60% is achieved, the installation depth is reduced, for example by 20%, the costs are reduced
• Ease of servicing is increased, since repair, service and cleaning work can be carried out on the workbench due to the quick removal, installation and exchange of the display modules and no longer have to be carried out in the vehicle when installed, 00 J 1 ra d 00 d ⁇ d TJ -H ⁇ t «M ⁇ ⁇ d" ⁇ do ⁇ d rH rö d W SH -H ⁇ d TJ dd XI TJ rH cn ⁇ j -H
• Another advantage that results from the reduction of extraneous and interfering light influences is that the automatic dimming of the light sources depending on the external ambient light surrounding the vehicle can function more reliably and more precisely, because of this in the display or in its immediate vicinity Nearby light sensors are less disturbed by diffuse scattered light from the display and can be better shielded from the light coming from the passenger compartment.
