• FIG. 2 is a schematic view in vertical section of the display device of FIG. 1,
• FIG. 3 is a detail view showing how the screen of the device in FIG. 2 can be mounted,
• and FIG. 4 is a block diagram of the control circuit corresponding to the display device of FIGS. 1 and 2.

In the different figures, the same references denote identical or similar elements.

Figures 1 and 2 show a device display 1, for example in the form a display panel intended to be placed in a public place, such as a public thoroughfare, an airport, a train station, a shopping center, etc.

The display device 1 comprises a chest exterior 2 closed, rigid, which can for example rest on the ground by means of a foot 2a, or which may be the case if necessary be fixed on a wall or similar. Chest exterior 2 has a front face with an opening 3 transparent, generally closed by a window 4.

Inside the trunk 2, behind the window 4, at least one poster 5 which can be used is placed advertising or general information. This poster can be fixed inside the trunk 2 by being stretched on a frame 5a or similar. Poster 5 can be made of paper, or in the form of a sheet translucent synthetic, which can advantageously be backlit by means of light bars 2b or similar.

Poster 5 is, for most of its surface, sufficiently opaque for an observer located outside trunk 2 can't see inside of this chest through the poster. However, a part of the surface of the poster 5 is constituted by a window 6 optically transparent, which allows to see a interior display image display device 7 through poster 5.

Window 6 can be constituted for example by a sheet of transparent flexible synthetic material, but if necessary, said window 6 could be constituted by a simple opening hollowed out in the poster 5. This window 6 has a rectangular shape in the example shown in the drawings, but said window could have any other geometric shape desired and / or any other dimension and / or any other position at within poster 5.

The electronic screen 7, for its part, can example be a device for presenting images to plasma, liquid crystal, diode electroluminescent, cathode ray tube, or other.

Screen 7 may have dimensions above window 6 of poster 5, in which case this image display device is controlled so to present an interior display 7a on only one active portion of its surface, called window below active, which active window is arranged, sized and shaped so as to be in correspondence with window 6 of poster 5.

Thus, the interior display presented by the screen 7 can be adapted to size and / or location and / or in the form of window 6 of poster 5, in the limits of the total screen area 7.

In addition, to allow adaptation to different possible locations of window 6 on the set of the surface of the poster 5, the screen 7 may possibly be movable inside the boot 2.

So, as shown in Figures 2 and 3, screen 7 can optionally be moved horizontally and vertically, parallel to the glass 4. For this purpose, the screen 7 can possibly be mounted sliding horizontally in direction 8a, out of two horizontal slides 8, and said slides can be mounted sliding in the vertical direction 9a on two vertical slides 9 fixed inside the boot 2. If necessary, the two horizontal rails 8 can be connected between they, at their ends, by spacers 8b which can themselves be slidably mounted in the vertical slides 9.

Adjusting the position of the screen 7 using slides 8, 9 can be manual if necessary, but this setting is preferably automated and controlled by example by motors M1, M2 (see figure 4) which drive the screen 7 respectively horizontally and vertically, by means of any drive device known such as jacks, cables, or the like.

As shown in Figure 4, the device display 1 can advantageously be controlled by a electronic central unit 10 (CPU), which may include in particular a microprocessor MP, a memory MEM and a clock H. The microprocessor MP controls the operation of screen 7, and in particular broadcasting by this image presentation device 7, of a program indoor display (video, series of photographs, animations, etc.), only within the active window 7a whose dimensions and / or positioning and / or form within the screen 7 are controlled by the MP microprocessor, based on stored parameters in MEM memory.

• un lecteur 11 (L) adapté pour lire un code 5b porté par l'affiche 5 et identifiant cette affiche, par exemple un code à barres lisible optiquement ou un code d'une autre nature,
• un lecteur 12 de support de données (DR), tel qu'un lecteur de CD Roms, de DVD, de disquettes, de bandes magnétiques, ou autres,
• une interface de télécommunication 13 (COM), telle qu'un modem associé à une ligne téléphonique filaire ou à un dispositif de télécommunication radio,
• et, lorsque la position de l'écran 7 est réglable et motorisée, des moteurs 14, 15 (M1, M2) adaptés pour régler la position de l'écran 7.

When the position of the screen 7 is adjustable in the trunk 2 and this setting is motorized, the microprocessor MP can optionally be connected to any
or some of the following:

• a reader 11 (L) adapted to read a code 5b carried by the poster 5 and identifying this poster, for example an optically readable bar code or a code of another nature,
• a data carrier (DR) 12, such as a CD-ROM, DVD, floppy, magnetic tape, or other reader,
• a telecommunications interface 13 (COM), such as a modem associated with a wired telephone line or with a radio telecommunications device,
• and, when the position of the screen 7 is adjustable and motorized, motors 14, 15 (M1, M2) adapted to adjust the position of the screen 7.

The device which has just been described works as following.

• téléchargement depuis un poste central informatique éloigné (non représenté), par l'intermédiaire de l'interface de communication 13, soit à l'initiative de l'unité centrale 10, soit à l'initiative du poste central éloigné,
• chargement par l'intermédiaire du lecteur de support de données 12, à partir d'un support de données introduit dans le lecteur 12 par l'opérateur qui change l'affiche.

When an operator changes the poster 5, the bar code 5b or other coding of this poster can be read by the reader 11, so that the microprocessor MP of the central unit can determine which poster it is and what are the interior display program (s) (videos, photo series, animations or others) which correspond to this poster and what are the dimensions and / or the positioning and / or the shape of window 6 of the poster. All this data can be stored for example in the memory MEM of the central unit 10, for example by one of the following processes:

• downloading from a remote central computer station (not shown), via the communication interface 13, either on the initiative of the central unit 10, or on the initiative of the remote central station,
• loading via the data medium reader 12, from a data medium introduced into the reader 12 by the operator who changes the poster.

From this data, the microprocessor MP positions screen 7 at the back of window 6 using motors 14, 15, if it is a presentation of mobile images with motorized control, and said microprocessor also determines the dimensions and / or the form and / or location of the display interior 7a presented in the active window of screen 7, so that this active window is coincidentally the as exact as possible with window 6.

Subsequently, the microprocessor MP displays, only in said active window 7a, the program indoor display to present to the public, and made also, if necessary, broadcast sound corresponding to this interior display on speakers associated with display device 1 (not shown).

According to a variant of the invention, the adjustment of screen position 7 could be manual and performed by the operator when changing displays, or whatever setting could be deleted if necessary.

According to another variant, it would be possible constantly use the same active window on screen 7 (possibly representing all screen 7), in which case only the position of the display would be adjustable interior compared to poster 5, depending on the position of window 6 of this poster.

According to yet another variant, it would be possible to delete either the media player from data 12, i.e. the communication interface 13.

Furthermore, as is already known in the art display device 1 could include not a single fixed poster 5, but a plurality posters arranged in the form of a strip wound on motorized rollers (not shown) so that they can be presented sequentially behind the glass 4. In in this case, each of the posters can bear a bar code 5b different from the others, so that the microprocessor MP can determine at all times what are the interior displays to present, and what are the dimensions and / or position and / or shape of the display interior 7a to present in the active window of the screen 7 in correspondence with poster 5 in progress presentation.

Note that, when poster 5 is fixed, the reader 11 and bar code 5b could be if necessary be deleted, in which case we would load in the memory MEM of the central unit 10, the program indoor display to present on screen 7 and geometric parameters relating to this interior display 7a (position and / or dimensions and / or shape of the window active compared to the poster 5) when changing poster, either by download or by reading a data carrier via the reader 12, and this or these interior displays would be presented automatically by screen 7, without checking that there is correspondence between poster 5 and this display interior using barcode 5b.

Note also that screen 7 could be if necessary replaced by another device presentation of images, for example a presentation of scrolling posters, including the position overall would be adjustable inside the device display 1, for example by means of adjusting the position M1, M2 described above.
