[0001] Optical output system, aircraft and use of the optical output system in the aircraft

[0002] Description

[0003] The present invention relates to an optical output system for an aircraft for graphically outputting data. Furthermore, the invention relates to an aircraft having an optical output system for graphically outputting data. The invention also relates to the use of the optical output system for graphically outputting data in an aircraft.

[0004] The currently publicly known output systems for graphically outputting data, in particular displays, televisions and / or screens, in aircraft are not transparent and usually have an opaque housing and / or an opaque rear wall on the rear. Known panel technologies are increasingly enabling transparent output systems, although these known output systems all have the disadvantage in common in moving environments such as an aircraft that environmental influences such as incident light, movement, windows and / or other devices behind the output system are detrimental to the output of data, for example entertainment content. The output of data, in particular the image quality, the contrast ratio and / or the black level of the output data, by known output systems does not offer satisfactory quality in a variety of scenarios in an aircraft.Especially when light is incident from behind, for example from sunlight, the reproduction of an image on a transparent display is unsatisfactory because the image content is "outshone".

[0005] It is therefore an object of the present invention to eliminate, or at least partially eliminate, the above-described disadvantages of the prior art. In particular, it is an object of the invention to provide an optical output system for an aircraft for graphically outputting data, which enables improved data output in a particularly simple manner. In particular, it is also an object of the invention to provide an aircraft with an optical output system for graphically outputting data, as well as a use of the optical output system for graphically outputting data in an aircraft.

[0006] The above object is achieved by the patent claims. In particular, the object is achieved by an optical output system for an aircraft for graphically outputting data, having the features of independent claim 1. Furthermore, the object is achieved by an aircraft having an optical output system for graphically outputting data, having the features of independent claim 10, and by a use of the optical output system for graphically outputting data in an aircraft, having the features of independent claim 11. Further advantages and details of the invention emerge from the subclaims, the description, and the drawings.Features that are described in connection with the optical output system according to the invention naturally also apply in connection with the aircraft according to the invention, the use according to the invention and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to each other.

[0007] According to a first aspect of the invention, the object is achieved by an optical output system for an aircraft for graphically outputting data. The optical output system comprises a planar output device for graphically outputting data and a data interface device for providing data to the planar output device, wherein the optical output system is designed to be transparent at least in sections, wherein the optical output system comprises a planar shielding device and a switching device, wherein the switching device is designed to switch the planar shielding device between at least one transparent state and at least one opaque state for at least partially switchable optical shielding of the transparency of the optical output system.

[0008] The optical output system according to the invention is preferably to be understood as a display, screen, television and / or other optical output system. The optical output system according to the invention comprises both smaller output systems, for example from 8 inches diagonal, and larger output systems, for example up to 140 inches diagonal. The graphic output of data is preferably to be understood as optical and / or graphic output of information, still images, moving images and / or entertainment content, such as films and / or series. The planar output device is preferably to be understood as a panel for the graphic output of data. The planar configuration of the output device is preferably to be understood as a planar extension or substantially planar extension of the output device.The wording "X or substantially X" should be understood within the scope of the invention as a possible, minor deviation, for example due to manufacturing tolerances, material and / or process properties, without changing the underlying, intended function of the feature. The output device therefore preferably has a significantly greater extent in two spatial axes than in the third spatial axis. The curvature of the planar output device described in later sections is preferably disregarded in the above extensions. Within the scope of the invention, the optical output system, in particular the planar output device, is designed to be transparent at least in sections. An image surface for the graphic output of data from the optical output system and / or the planar output device is preferably designed to be completely or substantially completely transparent.The optical output system preferably comprises a stand or a fastening device for setting up and / or mounting the optical output system and / or a base body, for example, for accommodating the data interface device and / or a power supply device. The stand, the fastening device, and / or the base body are preferably designed to be non-transparent. In other words, the display area of ​​the optical output system for the graphical output of data is designed to be transparent or substantially transparent.

[0009] It represents an advantageous addition to the optical output system if the optical output system comprises an acoustic output device and / or an interface for an acoustic output device for acoustically outputting data. Preferably, the acoustic data is also provided via the data interface device. Within the scope of the invention, the acoustic output device is defined as a component of the optical output system or of the aircraft. The acoustic output device is preferably configured internally or separately from the optical output system.

[0010] The optical output system according to the invention is particularly advantageous because it comprises a planar shielding device and a switching device. The switching device is designed to switch the planar shielding device between at least one transparency state and at least one opaque state for at least partially switchable optical shielding of the transparency of the optical output system. In other words, the transparency of the optical output system can be clearly described and switched on and off by the planar shielding device and the switching device. The optical output system is therefore transparent in the at least one transparency state and opaque or at least less transparent in the at least one opaque state than in the transparency state.Illustratively described, the at least one transparency state has a first, high transparency value, and the at least one opaque state has a second, low transparency value. When describing the at least one transparency state and the at least one opaque state, it must be taken into account within the scope of the invention that, in practice, a completely transparent and / or completely opaque flat shielding device is obviously not feasible, or only approximately feasible.

[0011] The planar shielding device and the switching device thus enable improved graphical output of data and / or improved perception by a user of the optical output system. The previously described disadvantageous output of the data, in particular in the form of poor image quality, poor contrast ratio, and / or poor black level of the output data by transparent optical output systems, is advantageously avoided or at least improved by the planar shielding device and the switching device. In the opaque state, the graphical output of the data, for example, during operation in front of a window in an aircraft, is advantageously improved, and the graphically output data is more easily perceived by the user.Illustratively described, the planar shielding device and the switching device enable dimming of the transparency of the planar shielding device and thus the transparency of the optical output system to at least one opaque state, in which light penetration through the planar shielding device and thus through the optical output system is advantageously avoided or at least reduced. Illustratively described, the optical output system according to the invention preferably represents a display device with a switchable viewing plane.

[0012] The planar shielding device and the switching device preferably have a plurality of transparency states and / or a plurality of opaque states. The planar shielding device can preferably be continuously switched between transparent and opaque by the switching device.

[0013] The planar shielding device is preferably configured mechanically and / or electrically. In a simple embodiment, the planar shielding device is configured, for example, as a mechanical roller blind of the optical output system. The planar shielding device is preferably electrically switchable between at least one transparent state and at least one opaque state. Exemplary embodiments of an electrically switchable planar shielding device are described in the following sections.

[0014] The planar shielding device enables switchable optical shielding of the transparency of the optical output system, at least in sections. In particular, the planar shielding device enables complete or substantially complete switchable optical shielding of the transparency of the optical output system. In an installed state, the planar shielding device is preferably arranged behind the planar output device with respect to a viewing direction of the optical output system by a user.

[0015] Preferably, the planar shielding device has at least two shielding regions, wherein the at least two shielding regions can be switched differently, in particular independently of one another, between at least one transparency state and at least one opaque state by the switching device.

[0016] The planar shielding device preferably enables a homogeneous or substantially homogeneous background for the optical output system and / or the planar output device. The planar shielding device advantageously improves the image and optically eliminates and / or at least reduces the presence of interfering surfaces and / or devices, such as design elements and / or window openings of an aircraft, that are located behind the optical output system.

[0017] An optical output system designed in this way is particularly advantageous because it enables improved graphical output of data particularly easily, while improving the perceptibility of the graphically output data by a user.

[0018] According to a preferred further development of the invention, an optical output system can be provided in which the planar output device is designed for pixel-based output of data and / or comprises self-luminous pixels, in particular wherein the planar output device is designed as an OLED panel. Pixel-based output of data by the planar output device is preferably to be understood in such a way that the planar output device comprises a plurality of individually controllable pixels. These pixels are preferably designed to be self-luminous, so that no backlighting of the pixels is necessary and / or this is advantageously avoided. As a result, the optical output system according to the invention can advantageously be designed to be transparent. For example, the planar output device is designed as an OLED panel. Alternatively or additionally, the planar output device is designed as a QLED panel and / or preferably as a MicroLED panel.Preferably, the planar dispensing device is designed as a material-locking and / or one-piece dispensing device.

[0019] An optical output system designed in this way is particularly advantageous due to the design of the planar output device, since an improved graphic output of data and an advantageous transparency of the optical output system are made possible particularly easily, whereby the perceptibility of the graphically output data by a user is improved.

[0020] According to a preferred further development of the invention, an optical output system can be provided in which the planar output device and the planar shielding device are arranged, in particular directly, next to one another and / or one behind the other and / or in which the optical output system is designed in layers and / or as a sandwich structure and / or laminate structure. An optical output system designed in this way enables an advantageously thin construction of the optical output system and thus a low installation space requirement. A slim design of the optical output system represents a design-technically advantageous implementation of the optical output system and enables advantageous and attractive integration of the optical output system in an aircraft.Particularly preferably, the planar shielding device is designed as an electrically switchable planar shielding device for arrangement on, in particular directly on, the planar dispensing device. The sandwich comprising the planar dispensing device and the planar shielding device preferably comprises only a few millimeters in thickness or depth, for example, a maximum of 5, 3, or 2 millimeters. The planar dispensing device and the planar shielding device are preferably adhesively bonded to one another.

[0021] An optical output system designed in this way is particularly advantageous due to the design and arrangement of the planar output device and the planar shielding device, since an improved graphic output of data, advantageous transparency and a small installation space of the optical output system are made possible in a particularly simple manner, whereby the perceptibility of the graphically output data by a user is improved.

[0022] According to a preferred further development of the invention, in an optical output system, the planar shielding device can be designed as a switchable layer and / or film, is designed to be electrically conductive at least in sections, and / or comprises alignable liquid crystals for switching the planar shielding device between the at least one transparent state and the at least one opaque state. The planar shielding device is preferably designed as a plastic film made of PET. The planar shielding device preferably comprises liquid crystals that align themselves upon application or removal of a voltage to the planar shielding device in order to enable switching between the at least one transparent state and the at least one opaque state for at least partially switchable optical shielding of the transparency of the optical output system.The liquid crystals are preferably laminated into the planar shielding device. The planar shielding device preferably additionally or alternatively comprises an electroluminescent layer and / or an E-Ink layer. A design of the planar shielding device as a switchable layer and / or film represents an advantageously thin design of the planar shielding device. The layer and / or film is preferably glued to the planar output device, in particular over its entire surface. An optical output system designed in this way is particularly advantageous due to the design of the planar shielding device, since improved graphical output of data, advantageous transparency, and a small installation space for the optical output system are made possible particularly easily, wherein the perceptibility of the graphically output data by a user is improved.

[0023] According to a preferred further development of the invention, in an optical output system, it can be provided that the optical output system, in particular the switching device, comprises a switching interface, wherein the switching interface is designed to switch the planar shielding device between the at least one transparent state and the at least one opaque state by means of an external switching device. The switching interface is preferably designed for a detachable or permanently installed connection of the optical output system to the external switching device. Switching the planar shielding device between the at least one transparent state and the at least one opaque state by means of an external switching device is particularly advantageous for the use of the optical output system in an aircraft. In aircraft, visibility out of the windows must be guaranteed during takeoff and landing in order to comply with safety aspects.The optical output system can preferably be arranged at least partially in front of an aircraft window. Switching the planar shielding device between the at least one transparent state and the at least one opaque state by an external switching device preferably enables switching of the planar shielding device by aircraft personnel. The external switching device is preferably designed to dominate the switching device of the optical output system. In other words, the external switching device determines the state of the planar shielding device, even if the switching device of the optical output system switches to an opposite and / or different state. The external switching device is defined within the scope of the invention as a component of the optical output system and / or the aircraft.The external switching device switches the planar shielding device manually and / or automatically via a logic unit of the optical output system and / or aircraft. An optical output system configured in this way is particularly advantageous due to the external switching device, since improved graphical output of data, advantageous transparency, and a compact installation space for the optical output system are made particularly easy, wherein the perceptibility of the graphically output data by a user is improved, and the external switching device enables switching of the planar shielding device between the at least one transparent state and the at least one opaque state.

[0024] According to a preferred further development of the invention, an optical output system can be provided which comprises a protective layer, wherein the protective layer is arranged on a side of the flat output device facing away from the flat shielding device. The protective layer is preferably designed as protective glass and / or as a protective layer made of polycarbonate. The protective layer preferably has an outer or inner layer and / or coating to prevent splinters in the event of damage to the protective layer. The protective layer preferably has at least one fire protection device, such as a coating and / or material composition, in order to comply with fire protection regulations in aviation. The protective layer is preferably adhesively bonded to the flat output device.An optical output system designed in this way is particularly advantageous due to the protective layer, since an improved graphic output of data, advantageous transparency and a small installation space of the optical output system are made possible particularly easily, whereby the perceptibility of the graphically output data by a user is improved and the security of the optical output system is increased.

[0025] According to a preferred further development of the invention, in an optical output system, it can be provided that the optical output system comprises a protective device, wherein the protective device comprises a detection device for detecting at least one error state of the optical output system and / or the aircraft, wherein the protective device is designed to switch the planar shielding device into the at least one transparent state based on the detected error state. Within the scope of the invention, the protective device is preferably to be understood as a "failsafe" device, wherein the protective device enables switching to a predefined state, preferably the transparent state, upon detection of an error state.For example, the protective device enables the planar shielding device to be switched into the at least one transparency state when the optical output system no longer has power and / or when no more data is being provided to the optical output system. Switching into the at least one transparency state when an error state is detected occurs with a time delay or directly. The detection of the at least one error state occurs at intervals, continuously and / or is event-triggered. An optical output system configured in this way is particularly advantageous due to the protective device, since improved graphical output of data, advantageous transparency and a small installation space for the optical output system are particularly easily enabled, wherein switching into the at least one transparency state is enabled when an error state is detected.

[0026] According to a preferred further development of the invention, it can be provided in an optical output system that a transmittance of the visible light of the optical output system, in particular of the planar shielding device, in the at least one transparency state is at least 60%, preferably at least 70%, 80% or 90% and / or that a transmittance of the visible light of the optical output system, in particular of the planar shielding device, in the at least one opaque state is at most 40%, preferably at most 35%, 30%, 25%, 20% or 15%.It is particularly advantageous if the transmittance of the visible light of the optical output system, in particular of the planar shielding device, in the at least one transparent state comprises at least 60%, preferably at least 70%, 80% or 90%, since this enables a virtually unhindered or even unhindered view through the optical output system, in particular when no data is output graphically on the optical output system. On the other hand, it is particularly advantageous if the transmittance of the visible light of the optical output system, in particular of the planar shielding device, in the at least one opaque state comprises at most 40%, preferably at most 35%, 30%, 25%, 20% or 15%, in particular when data is output graphically on the optical output system.The above features are to be understood in each case such that at least one transparency state and / or at least one opaque state corresponds to the corresponding value. Preferably, in the case of multiple transparency states and / or opaque states, the transparency state and / or the opaque state with the highest or lowest transmittance of visible light corresponds to the corresponding value. An optical output system configured in this way is particularly advantageous due to the planar shielding device, since improved graphical output of data, advantageous transparency, and a small installation space for the optical output system are made possible particularly easily.

[0027] According to a preferred further development of the invention, in an optical output system it can be provided that the optical output system, in particular the planar output device, the planar shielding device and / or the protective layer, have a curvature and / or a radius. A curvature and / or a radius of the optical output system, in particular of the planar output device, the planar shielding device and / or the protective layer are particularly advantageous since, particularly with larger diagonals of the optical output system, an improved, in particular more uniform distance between the central regions and the edge regions to a viewing point and / or a seating position of the user is enabled. A preferred radius of the optical output system is preferably at least 0.7 m to 1.7 m.An optical output system designed in this way is particularly advantageous due to the structural design of the optical output system, since an improved graphical output of data, advantageous transparency and a small installation space of the optical output system are made possible particularly easily, whereby the curvature and / or the radius enables advantageous immersion of the user.

[0028] According to a second aspect of the invention, the object is achieved by an aircraft comprising at least one optical output system according to the first aspect. The described aircraft provides all the advantages that have already been described for the optical output system according to the first aspect of the invention. The optical output system is preferably arranged along the direction of flight of the aircraft or at an angle to the direction of flight of the aircraft. The optical output system is preferably arranged at least in section in front of an aircraft window, in particular at least in section in front of an aircraft roof window. The optical output system is preferably arranged in the passenger cabin of the aircraft and / or outside the cockpit of the aircraft. The previously described external switching device is defined within the scope of the invention as a component of the optical output system and / or of the aircraft.An aircraft designed in this way is particularly advantageous due to the optical output system, as it enables improved graphical output of data, advantageous transparency and a small installation space for the optical output system.

[0029] According to a third aspect of the invention, the object is achieved by using an optical output system according to the first aspect in an aircraft according to the second aspect. The described use results in all the advantages already described for the optical output system according to the first aspect of the invention and for the aircraft according to the second aspect of the invention.
