Description

Title of the invention: Holographic display device

The present invention relates to the field of display or holographic projection of images, fixed or animated, whether or not accompanied by sound, in particular in the commercial field, that of leisure and / or that of events. .

The invention more particularly relates to a holographic display device, a ready-to-assemble assembly (or kit) for its production and a system for presenting a plurality of articles comprising such devices.

Current display or real holographic projection techniques are based on structures and systems that are heavy, imposing, complex, cumbersome and expensive, and which also generate a great deal of noise pollution.

Thus, we already know hologram production systems based on a one-way mirror or semi-reflecting mirror positioned at an angle of 45 ° in front of the viewer and generating a hologram from an image projected at 90 °. Their size is important and the quality of the rendering generally poor.

Known systems generating holograms by transmission by means of a laser beam are inconvenient to implement and expensive.

Known systems generating holograms by means of a rapidly moving element (for example a helix or the like), and based on retinal persistence, are noisy and subject to intense wear.

Display systems for products or articles combining the real object and virtual images of this object, additional elements or scenes, superimposed are also known (augmented reality). These systems are also bulky and complex, and permanently require the real presence of the object, which can cause security problems in the case of products or articles of great value, or space in the case of products or d 'bulky items. The object of the present invention is to provide a holographic display device making it possible to overcome at least the main drawbacks listed above, and in particular making it possible to limit the size, the weight, the complexity, the cost and the maintenance. and to suppress any noise during operation.

In addition, the invention should also allow easy adaptation of the device to all shapes and sizes, and possibly allow marketing in pre-assembled form or in the form of a set or kit to be assembled by the user.

Finally, said device should if possible be able to operate autonomously, adapt according to the owner's wishes, interact with an outside observer and take account of his behavior and / or be able to communicate remotely.

To this end, the invention relates to a holographic display device, in particular for the virtual presentation of objects or articles in the form of a pseudo- or quasi-holographic representation, characterized in that '' it essentially comprises, integrated in a support frame:

- a front surface consisting of a solid layer of transparent, flat or curved material forming part of a block or a plate and bearing a marking, an engraving or a similar delimiting pattern forming a similar visual peripheral frame or border;

- an intermediate layer with reflective and transmissive optical properties, arranged in parallel and at a distance from the front surface;

- a rear surface or screen for displaying or projecting images, fixed or animated, two-dimensional or three-dimensional, positioned at a distance from the intermediate layer opposite the transparent front surface and,

- possibly at least one lighting means illuminating the transparent front surface,

the media located respectively between said surfaces and said layer being transparent and the arrangement comprising the front and rear surfaces and the intermediate layer being configured so as to generate for a spectator looking at said front surface, by optical illusion, between the frame or the border present on the transparent front surface and its reflection on the intermediate layer, a virtual holographic volume in which appears the image displayed on or projected from the surface or rear screen.

The figures of the accompanying drawings all show, in different forms and some only partially, a holographic display device 1, in particular for the virtual presentation of objects or articles 1 'in the form of a pseudo representation - or almost holographic.

According to the invention, this device 1 essentially comprises, mounted or integrated in a support frame 2: a front surface 3 constituted by a solid layer of transparent, flat or curved material, forming part of a block or plate 3 ′, 10 and bearing a marking, an engraving or a similar delimiting pattern forming a frame or peripheral border visual (the) analog 4;

- An intermediate layer 5 with reflective and transmissive optical properties, arranged in parallel and at a distance from the front surface 3;

- a rear surface or screen for displaying or projecting 6 images 7, fixed or animated, two-dimensional or three-dimensional, positioned at a distance from the intermediate layer 5 opposite the transparent front surface 3 and,

- optionally at least one lighting means 8 illuminating the transparent front surface 3.

According to the invention, the media 9, 9 'located respectively between said surfaces 3, 6 and said layer 5 are transparent and the arrangement comprising the front surfaces 3 and rear 6 and the intermediate layer 5 is configured so as to generate for a spectator looking at said front surface 3, by optical illusion, between the frame or the border 4 present on the transparent front surface 3 and its reflection 4 ′ on the intermediate layer 5, a virtual holographic volume in which appears the image 7 displayed on or projected from the surface or the rear screen 6.

Thanks to the invention, it is possible to propose a system for displaying quasi-or pseudo-holographic images which is of simple construction, of low cost, of reduced bulk, devoid of mobile element (system passive) and generating no noise.

The illusion of volume and depth created by the illusion of perspective between, on the one hand, the frame or the actual border (the) 4 present on the outer face of the front surface 3 (or near the latter) and, on the other hand, its reflection 4 ′ on the intermediate layer 5, in the manner of a trompe l'oeil for the spectator 1 1 positioned facing the front surface 3, contributes to the production of a three-dimensional pseudo hologram (from a two- or three-dimensional image), floating in the space (medium 9) extending between the front surface 3 and the intermediate layer 5. It may be noted that the rear display or projection surface 6 can be located at a variable distance at the rear (relative to the front surface 3) of the intermediate layer 5, depending on the type of surface, available space and image size.

The edge 4 advantageously extends near the outer periphery of the area visible to the viewer 1 1 of the device 1, at the front surface 3.

The rear surface 6 displaying or projecting the two- or three-dimensional image 7 is advantageously located as close as possible to the intermediate layer 5. The relative arrangement of the intermediate 5 and front 3 layers, and the distance separating them, is a function of the size of image 7 and of its holographic reproduction 7 ′ (the larger the screen 6 and therefore the image 7 is large, the greater the distance between these layers 3 and 5).

The possible lighting means 8 makes it possible to get rid of any influence from any external lighting and to increase the visibility of the reflection 4 ’of the frame or of the border 4 at the intermediate layer 5.

This lighting means 8, which illuminates the support (plate 3 ') of the first front surface 3, whether homogeneous or not, is advantageously integrated into the support frame 2, over its entire periphery / circumference or not, and can come in different designs: LED, OLED, LCD panel or the like.

Advantageously, and to allow interaction with a viewer 1 1, by analyzing his behavior, his expression and / or his gestures, the device 1 can also include, preferably at the level of its visible front face, at least a camera 12 and at least one sensor 12 ′, forming part of means for interfacing and / or human / machine interaction. These means 12, 12 'are advantageously connected to a circuit or a processor card 13 managing, on the one hand, said means 12, 12', the screen or the display or projection surface 6 and the possible means lighting 8 and, on the other hand, wired and / or radio communications with the outside via ports or sockets 14 and wireless transmission / reception circuits (not shown).

Preferably, the device 1 consists of an autonomous module, in particular functionally and / or energetically, advantageously integrating a rechargeable battery by wire or by induction. The base or lower part 16 of the module 1 can integrate a receptive induction loop connected to the battery and able to cooperate with a charger 18 with an emissive induction loop (cf. FIG. 11).

The device 1, or rather its support frame 2, can advantageously be fitted with plugs and ports 14 for connection and plug-in of different types, such as USB, USB-C, Micro-SD, Nano-SIM. In addition, status and operation indicator lights 19 and at least one control button 19 ’can also be provided.

In accordance with a first embodiment of the invention, particularly emerging from Figures 3, 4 and 6A, the media 9, 9 'separating each of the two surfaces 3, 6 of the intermediate layer 5 are made of air .

Advantageously, in relation to this first embodiment, and as shown in particular in Figures 3, 4, 6A and 6B of the drawings, the front surface 3 corresponds to the outer face of a transparent plate 3 'or glass clear, for example of the crystal type, or of polymer, such as polymethyl methacrylate (PMMA) for example.

The intermediate layer 5 may in turn be arranged on a plate 5 'of transparent material, for example a float glass plate, so as to constitute a partially reflecting and partially transmissive mirror (in particular semi-reflecting and semi-transparent ), said layer 5 being located on the face of the plate 5 ′ facing the front surface 3.

As shown by comparison in Figures 6A and 6B, the layer 3 'supporting or providing the front surface 3 may have a greater or lesser thickness, the volume (medium 9) located between said surface 3 and layer 5 being therefore more or less made up of air (in FIG. 6B, the layer (thick plate or block 3 ′) carrying the front surface 3 extends practically to the intermediate layer 5).

In accordance with a second embodiment of the invention, emerging by way of example of Figures 5, 6C and 7 to 1 1, the frame 4 and the intermediate layer 5 are attached or formed on two opposite sides d '' same block or same plate 10 of transparent material (s), said frame 4 being present on or in said front surface 3 (a short distance from its outer face).

This block or this plate can be made of a single transparent material of index greater than 1 (PMMA, clear glass, crystal) with a semi-reflective treatment 5 on the rear surface and an engraving or a marking surrounding 4 analogous on the outside of the front front surface 3.

As a variant, the frame 4, for example engraved, may be located a short distance inside the front external face of the block 10, that is to say on the internal face of the surface 3.

This block or this plate can, as a variant, also consist of a laminated structure of several sublayers formed from different transparent materials, possibly having different reflection / transmission coefficients (PMMA, glass, crystal).

In accordance with an optional characteristic, emerging from Figures 6B, 9 and 10, a plate 5 'of a transparent material (clear glass in particular, crystal, or PMMA) can be attached to the rear face of the block 10, with interleaving of the semi-reflecting and semi-transparent dielectric layer 5 (in the form of a film, of paint or the like), placed on the plate 5 ′ or on the block 10. This plate 5 ′ can also be located at a distance from the rear face of block 10.

Preferably, and as shown by way of example in FIGS. 1, 2, 4, 5 and 8, the support frame 2 constitutes, where appropriate in cooperation with the rear display or projection surface 6, a visually opaque envelope with a front opening 2 'closed by the transparent front surface 3.

In Figure 3, the support frame 2 is closed on the rear face, while in Figures 3 and 4 the rear face of said support frame 2 (frame-shaped) is closed by the surface or the screen d display or projection 6.

According to a preferred construction characteristic, the intermediate layer 5 consists of a film of metal oxide (s), of the type which is attached to a hot or cold glass substrate, for example by a pyrolytic method or a cold layer deposition, and has a thickness of between approximately 10 and about 800 nanometers, and is preferably made up of several superimposed sublayers.

Thus, the layer 5 can be applied to the concerned face of the block or plate 10 of cold crystal, then baked and hardened on this face during a passage in an oven (with possibility of adaptation and adjustment of optical characteristics).

The semi-reflective layer 5 can also be constituted by a layer of material, forming an insulated plate or integrated into a laminated plate with several layers, having a refractive index greater than or equal to about 1.4.

According to yet another constructive variant, the semi-reflecting intermediate layer 5 can be constituted by a self-adhesive semi-transparent mirror film attached to a rear face of the plate or block 10, 3 ′ of transparent material.

Advantageously, the optical transmission coefficient of this layer 5 is between 8% and 92% approximately, preferably between 15% and 85%, and its reflection coefficient is between 8% and 92% approximately, preferably between 15 % and 85%.

A means 6 for diffusing or projecting images 7 at high brightness makes it possible to overcome, where appropriate, the limits of the above ranges of coefficients and to implement any coefficients.

The constitution of this layer and its embodiment are known to those skilled in the art (one can for example refer for specific details to the site www.verreonline.fr).

Regarding the rear surface 6, different technical solutions can be envisaged depending on the quality, size and resolution desired for the holographic image 7 ', and the space available, technology restraint, cost or similar parameters. The source of the video images can, of course, be arbitrary.

Thus, it can for example be provided that: the rear surface 6 consists of a screen of a monitor of the liquid crystal, plasma, OLED, AMOLED, micro-LED or similar type;

- The rear surface 6 consists of a film screen attached to the rear face of a transparent support;

- The rear surface 6 is formed by the projection surface of a video or laser projector.

Similarly, the support frame 2 can be declined in different forms, sizes and constituent materials.

As shown in FIGS. 7 and 8, the support frame 2 can consist of:

- a box or frame of polygonal shape, in particular square or rectangular; or

- a housing or frame with a rounded periphery, in particular circular or elliptical.

As indicated above, the holographic display device 1 according to the invention can optionally be associated with or integrate means of interfacing and / or human / machine interaction, in the form of image taking means. 12, interactive cameras (for example of the Kinect type - registered trademark), motion sensors 12 ′, joysticks, capacitive films or infrared sensors 12 ′.

The use of a lenticular film and / or a domed front surface 3, making it possible to add a volume effect, allows the viewer to see the different faces of the object / article forming the hologram 7 'by moving in front of the front surface 3, or even around the sides of the support frame 2 when the latter is transparent.

In agreement with a preferred constructive variant of the invention, corresponding to an intelligent connected and autonomous device 1, the latter consists of a module formed essentially by a set of three constituent parts 15, 15 ′, 15 ”, namely, on the one hand, a main body 15 integrating at least the surface or the screen 6, at least one lighting means 8, means 12, 12 ′ for interfacing and man / machine interaction, at least one battery rechargeable, plugs and connection ports 14 and means for wired and / or radio communication, on the other hand, a transparent block or plate 10 with a frame or border 4 attached or engraved on or near its apparent front surface 3 and a layer 5 with optical properties on its opposite face, and, finally, a frame 15 ′ securing the block or plate 10 with the main body 15, surrounding them laterally and providing a front opening 2 ′ revealing the front surface 3 at least, said body 15 and said frame 15 'together forming the support frame 2 (figs 7 to 18).

Finally, the invention also relates to a system for presenting a plurality of articles or objects in multiple locations, which can combine a physical presentation and a virtual pseudo-holographic presentation, this system comprising a plurality of individual presentation devices dispersed geographically and connected to a centralized, local or remote management and control platform.

The platform can be that of the store in the windows of which the articles 1 'are for sale and displayed (and displayed) on the modules 1 or then belong to a service provider managing a fleet of modules 1 and owner of the system, these modules 1 being distributed over a plurality of sales and / or exhibition sites.
