Description

Picture display device

The invention relates to a picture display device with a housing and a screen. In particular, the invention relates to a picture display device which can be designed from an artistic point of view or design technical point of view of an object designer.

There is a great need for the illumination of building interiors or the lighting design of areas outside of buildings. In addition to the artistic value of an individual (in particular, unique) lighting design of objects, individual designs can also influence the attitude towards life of people who are in the illuminated area.

In addition to lighting designs, individual images and / or color designs are required, which do not necessarily have to have a lighting function in each case.

It is an object of the present invention to enable a design of an object that can be performed individually in an almost unlimited manner. In this case, the visible external appearance of the object should be able to be produced inexpensively and the area or areas that can be designed individually, be clearly distinguishable from adjacent areas. In addition, the design should be robust and external loads, especially in the area that can be designed individually, withstand. Furthermore, it should be possible to distinguish also different visually individually customizable areas in a simple manner against each other and / or subdivide by a demarcation.

There is proposed a picture display device comprising a housing and a screen. On the screen according to predetermined image content and / or predetermined image data almost any images, colors, symbols or other visually recognizable designs can be displayed. According to the invention, at least part of an outer surface of the housing is formed by a glass brick. The screen is arranged in the housing or in the glass block such that an image displayed on the screen or a part thereof can be perceived when viewing the outer surface formed by the glass block. Depending on the design of the glass block, depending on the orientation and distance of the screen relative to the glass block and, optionally, depending on the design and arrangement of objects between the screen and the glass block, the image displayed on the screen is perceived differently when looking at the outer surface of the glass block, as this would be the case with direct viewing of the screen. It can therefore be achieved alienation of the image displayed on the screen. In particular, parts of the image can not get to the outer surface of the glass block and / or be changed, for example, by diffraction, absorption or scattering of light.

Under a glass block is understood in particular a conventional glass block, which can be used in the construction of buildings use. Typical of a conventional glass block are two outer surfaces, one of which may form an inner surface of the housing and the opposite outer surface forms the outer surface of the housing. In another embodiment of the invention, however, the screen can also be arranged in the interior of the glass block, ie between the outer surfaces of the glass block. This embodiment will be discussed in more detail.

Furthermore, it is characteristic of conventional glass blocks that the area lying between the outer surfaces of the glass block has a self-contained peripheral outer edge, which comes into contact with building materials such as mortar or other adhesive materials when installed in buildings. It is customary that the said outer edge extends in a groove-like recessed area, so that, for example, said building materials can be introduced into this area. Looking at such a conventional glass block from a direction approximately perpendicular to the course of one of Exterior surfaces, located behind the outer edge of the outer surface is not continuous material of the glass block.

Specifically, a glass brick is also understood to mean an article having the shape and / or dimensions of a glass brick which is also made of translucent material (not necessarily, but preferably transparent), but this material is not conventional glass (ie amorphous, non-crystalline solid) but any other transparent or transparent material, eg polymeric plastic or transparent crystalline material.

The glass block forms a stable component of the housing, in particular if it is a conventional glass block for the construction industry. At least from the side of the screen on which the glass block is located, the screen is therefore well protected.

This also applies if the screen is in the glass block. In this case, the glass block itself forms the housing. For example, the screen is introduced during manufacture of the glass block between two halves of the glass block, the two halves each define one of the opposite outer surfaces of the glass block and define a cavity between them, which also remains in the finished state of the glass block. In this cavity, the screen is then arranged. Further, at least one passage for performing electrical connections to the screen can be provided on the lateral edge of the glass block between the outer surfaces, which is for example already included in the baking of the two halves of the glass block. About such electrical feedthroughs, the screen can be supplied with electrical energy and optionally with image signals that define the or images to be displayed. About such electrical feedthroughs that connect the cavity with the outside world of the glass block, it is also possible, a plurality of glass blocks and each arranged therein screens with each other and / or with a common Control device and / or power supply to connect. For example, these multiple glass blocks can be arranged as a wall of glass blocks.

In addition to its stabilizing and protective function, a glass block has the visual effect, which can be perceived from outside the housing, that it forms a frame for the outer surface due to its self-contained peripheral edge, upon viewing of which image contents can be seen that are generated by the screen. The glass block thus forms a visually perceptible demarcation of the outer surface against adjacent areas.

In particular, a plurality of the glass bricks can each form part of the outer surface of the housing, so that an image displayed on the screen or a part thereof can be perceived when viewing the outer surface formed by the glass bricks. The individual parts of the outer surface of the housing which are formed by the glass blocks are therefore delimited in a frame-like manner. For example, with a suitable design of the image displayed on the screen, the impression can be created that there are several image sources or screens in the housing, each of which generates an image which is perceived when viewing one of the glass blocks. But even when creating an image that extends over the outer surfaces of several glass bricks, the frame-like outer edges of the glass bricks are beneficial. They define image areas, which can thus be delimited against other image areas and can be designated, for example, by designations such as "image segment 1" or "medium image area". In addition, it is of course also possible to arrange more than one screen in the housing, wherein, for example, each of the screens generates an image that can be perceived only when viewing one of the outer surfaces of the various glass blocks. But it is also possible to superimpose the images of the multiple screens on the same outer surface of a glass block. For overlapping z. As mirrors or other optical elements are used inside the housing. A special optical effect can be achieved in that an object is arranged in the housing between the screen and a housing-inside surface of the glass block. The article may be at least partially translucent, so that it can be recognized when viewing the outer surface of the glass block (ie, the housing-outside surface of the glass block). In this case, the screen can not only emit, for example, monochromatic light on the object, but alternatively also images, so that the object appears, for example, as if it is designed according to the nature of the image.

The housing may be e.g. to act a cuboid box with six outer sides, wherein at least on one of the outer sides or one of the six outer walls of the cuboid, a glass block is arranged and forms with its outer surface at least part of the outer surface of the respective wall.

The glass brick may be integrated into the outer surface of the housing so as to be flush with adjacent portions of the outer surface of the housing without forming a protrusion or depression. But the glass block or the glass blocks can also form a projecting part or a recessed part of the outer surface of the housing.

In turn, a screen can be arranged in the housing, which has its own housing, in which e.g. a control device for controlling the actual screen and / or an image data memory is / are included. This inner screen housing is preferably supported on multiple sides against the outer housing and / or fixed, so that a stable arrangement is achieved.

The image signals that lead to the representation of one or more images on the screen can be generated, for example, corresponding within the housing stored image data within the housing. Alternatively or additionally, however, image signals can also be fed from the outside into the interior of the housing to the screen. Further, it is possible to change the image signals and / or the image data. Alternatively or additionally, the image data and / or image signals themselves may already have the image information for time-variable images, in particular for a film. It is therefore not only possible to display a single image on the screen, but also time-varying images or movies.

The screen may be any type of screen, e.g. a CRT screen, a flat screen with liquid crystal display, a Surface Conduction Electron Emitter Display (SED), a plasma display, or an OLED (Organic Light Emitting Diode) screen. It is preferred to use a TFT (Thin Film Transistor) flat panel display.

As a screen, e.g. a TFT display of the Winstar Display Corporation, Artilel no. WF 320240 A-TXI can be used. As the control means for driving the display, e.g. a controller of the type S1D13A05 Seiko Epson Corporation are used. The controller of the screen may in turn be driven by a VGA signal, e.g. Picture sequences or movies on the screen. The VGA signal may come from a commercially available computer graphics card, e.g. can be located in the housing and is preferably equipped with an image data storage, the storage medium can be replaced. In this way, by inserting a new storage medium with other image data, the image sequence to be displayed on the screen can be changed.

If a translucent object is arranged between the screen and the housing-inside surface of the glass block, this object is preferably arranged in a section of an opaque article, for example in a section of a wooden plate or metal plate. The section has z. B. on the shape and size of the outer contour of the object. The object is fixed for example by adhesive on the edge of the cutout. As a result, light from the screen can only pass through the translucent article on the way to the glass block. Embodiments of the invention will now be described with reference to the accompanying drawings. The individual figures of the drawing show:

FIG. 11 shows a vertical section through the housing according to FIG. 9 and FIG. 10, wherein the section runs perpendicular to the image plane of FIG. 9 and FIG. 10; FIG. 12 shows a glass block with a cavity in which a screen is arranged, and Fig. 13 shows an arrangement with four glass blocks, each having a screen and which are electrically connected to each other.

Fig. 1 shows a conventional glass block, which consists of one piece of glass. A middle region 2 is between a front cuboid region 4 and a rear cuboid area 3 formed. The areas 3, 4 each consist of a glass plate. The front cuboidal region 4 forms a front outer surface 5. The rear cuboidal region 3 forms a rear outer surface 6. The central region 2 may be treated and / or provided with a suitable material such that conventional construction materials such as mortar or sealant well on the Adhere to outer surface of area 2. The front outer surface 5 and the rear outer surface 6 are each arranged rectangular and parallel to each other. The central region 2 can either be made of glass or can have a hollow space in its interior. Since the outer edge of the parallelepiped-shaped regions 3, 4 extends further outward than the outer surface of the central region 2, a groove-like space 8 for receiving building materials, which extends circumferentially around the middle region 2, is formed.

The glass block 1 according to Fig. 1 can e.g. by merging (baking) a front half and a rear half of the glass block 1 are produced. If the front half has the front rectangular area 4 and about half of the central area 2 and the rear half has the corresponding remaining area of the glass block, before the baking a screen 120 with a picture surface 121 for displaying images in one through the middle Area 2 defined cavity are introduced (Fig. 12). Furthermore, through the wall of the central region 2, a passage 122 for performing electrical connections 123, 124 may be provided.

For example, as a passage, a metal sleeve is melted into the wall of the central region 2 during baking. The metal sleeve defines a passage opening through which electrical connections from outside the glass block into the cavity of the central region 2 can lead. This makes it possible, in particular, to control the screen 120 with image signals and / or to transmit image data into the cavity and / or to supply the screen 120 with electrical energy. In addition to the screen 120 shown in FIG. 12, a control device for controlling the screen 120 and / or an image data memory can also be located in the cavity of the glass block.

FIG. 13 shows that a plurality of glass blocks 130a to 13Od, each having at least one screen in its interior (not shown in FIG. 13), may be electrically connected to each other via electrical connections 131 to 136.

Unlike in Fig. 13, the glass bricks 130 may form a wall of glass bricks in which the voids shown in Fig. 13 are closed, e.g. in that the glass blocks abut one another and / or via mortar or adhesive sealing material, e.g. Silicone, bonded together.

A wall of glass blocks (this applies not only to the glass blocks, each having a screen in its interior, but also for glass blocks of FIG. 1 to FIG. 11, which form part of an outer surface of a housing) can also loose or fixed be connected to other objects. For example, For example, a housing with at least one glass brick can be integrated in a surface of a trade fair stand or in a surface of a rear wall of a drinks bar.

FIG. 2 shows a cuboidal housing 21, the outer surface of the cuboid being shown at a front side of the housing 21 shown at the bottom left in FIG. 2 essentially by a glass block 1, e.g. the glass block 1 shown in Fig. 1, is formed. However, a part of the front side is also formed by frontal surfaces of wall elements 36, 37, 38 and 39 of opaque material. The wall element 36 forms part of the ceiling of the housing 21. In a rear region of the housing 21, however, it is shown open at the top.

As can be seen from Fig. 3, a lid 31 can close the opening, so that the lid 31 and the wall member 36 form the upper surface of the housing squared. In the illustration of Fig. 2, the wall member 37 forms the right Side surface, the wall member 38 forms the left side surface and the wall member 39 forms the bottom of the housing 21st

As can be seen in FIGS. 2 and 3, a rear wall 32 of the housing cuboid has a plurality of ventilation slots 34 and a passage opening 33 for the passage of electrical connections.

As best seen in Fig. 3, in the central area 2 of the glass brick 1, there is a gap to the wall elements 36 to 39 due to the space 8, which is preferably at least partially filled with adhesive or adhesive sealing material, e.g. Silicone. In this way, the glass block 1 is reliably connected to the wall elements 36 to 39.

The arrangement shown in FIGS. 4 to 6 has a screen 61 with an image surface 62 which is approximately as large as the visible cross-sectional area of the central region 2 of the glass component 1. The image surface 62 becomes directly behind the cuboid region 6, ie 8), wherein, however, an air gap 81 remains between the frame of the screen 61 formed from elements 44 to 47 and the housing-inside surface of the glass brick 1. The air gap allows for improved removal of the heat generated by the operation of the screen 61 by convection. The heated air can escape to the outside of the housing 21 via the ventilation slots 34.

Angle profiles 43a, 43b are attached to the frame 44-47. These angle profiles 43 on the one hand have the function that the frame 44 to 47 on the angle sections 43 on the lateral wall elements 37, 38 is supported, also supported on the standing on the lower wall element 39 angle sections 43 down and in turn also the angle sections 43 with their ends in front of the frame 44 to 47 projecting ends 65, 66 are supported on the cuboid region 6 of the glass block 1. In this case, an air gap remains free between the frame component 45 and the bottom-side wall element 39 as well as between the upper frame element 44 and the closed cover 31 at the top the air in the interior of the housing 21 can flow through the air gaps and has the aforementioned cooling effect for the screen 61.

The screen 61 extends (not shown) e.g. at its outer edge circumferentially in a in the frame members 44 to 47 on the inside incorporated groove and is held securely.

With the frame 44 to 47 further components of the arrangement shown in Fig. 4 to Fig. 6 are connected via four screws 51 a to 51 d. Immediately above the screws 51, a plate 41 is connected. With the plate 41 a arranged at the back of the first board 42 via screw 53a, 53b is connected. At the front of the plate 41 is connected to this again via screw 52a, 52b, a second board 48.

The second board 48 carries e.g. electrical and microelectronic components, in particular with an image data memory with replaceable storage medium, so that an image signal, such as a VGA signal, from the components to the second board 48 via components, not shown, to components (also not shown) are transmitted to the first board 42 , The electrical and / or microelectronic components carrying the first board 42 may receive the image signals, in particular the VGA signal, and convert them into control signals for driving and operating the screen 61. For transmitting these control signals at least one further (also not shown) electrical line connection to the screen 61 is present.

The second embodiment of a housing 90 illustrated in FIGS. 9 to 11 has three glass blocks 91 a, 91 b, 91 c which form part of the outer surface of the housing 90 on the front side illustrated in FIG. 9. As can be seen from FIG. 11, the outer surface protrudes against the glass blocks 61.

The housing 90 has a cavity 100 in the upper portion of a monolithic, upstanding block-shaped block 98 having a bottom foot 99. The illustration of Fig. 10 shows the interior of the cavity 100, which is formed by wall elements 92a to 92e. In the cavity 100 is a commercial screen 93 with a rectangular image area 94 for displaying images. The screen 93 has feet 97a, 97b with which it stands on a bottom of the cavity 100. The commercial screen 93, which can be connected directly to a computer, for example, already contains the control means for generating the control signals with which the actual screen with the image surface 94 is driven. The control signals are generated for example from a VGA signal, which is supplied from outside the cavity 100 via an electrical line connection, not shown, the screen 93.

The image surface 94 runs parallel to the housing-inside surface of the glass bricks 91. The image surface 94 is dimensioned and arranged relative to the housing-inside surface of the glass bricks 91, that when viewing the housing-outside surface of the glass bricks 91 no edge of the image surface 94 can be seen, or in other words, the entire visible from the outside when viewing the glass blocks 91 surface as a screen of the screen 93 is used. Conversely, therefore, it may be that some of the images displayed on the image area 94 are not recognizable from outside the housing 90.

The screen 93 and in particular the image surface 94 are arranged at a distance from the housing-inside surface of the glass blocks 91, as shown in FIG. 11 can be seen. Again, vents (not shown) may be provided in the housing 90 so that the air can escape from the cavity 100 and fresh, cooler air can be supplied. This is preferably done without forced ventilation, i. by natural convection.

As can be seen from FIGS. 9 to 11, the plurality of glass bricks 91 can have a common frame, which consists for example of the illustrated frame elements 95a to 95d. This frame 95 may be fixedly connected to one of the wall elements (in this case wall element 92d) on its outside, for example glued and / or taped and / or screwed. The frame 95 is preferably in turn, for example, as already described with reference to the embodiment of FIG. 2, connected to the frame members 95a to 95d.

Quite generally, the glass bricks according to the present invention can be clear glass bricks, so that at most slight distortions of the glass surfaces result in distortion of the images produced by the screen in the interior of the housing. It may be the glass blocks completely or partially but also those that deliberately lead to a change in the images generated by the screen. For example, For example, at least one of the glass surfaces relevant to the passage of light of the images produced can be structured, matted and / or otherwise deviate from a flat glass surface. This also includes the possibility that the glass surface is completely or partially coated and / or has an optical lens effect. Further, e.g. Inclusions in the glass material possible, so that the light is diffracted when passing through, scattered and / or completely or partially absorbed. In particular, only a part of the frequency spectrum of the light passing through can be influenced, so that color effects are achieved.
