Description

Title : A portable 3D media projection tabletop display device

Background:

Often, 3D projection visualizations ave used by businesses for marketing campaigns tc generate superior user engagement in public places, such as in events, trade shows, and retail. Different techniques are available in the market for creating 3D projection visualizations to engages the audience. Most of these techniques use sore sort of Hiusions to weate a 3D effect, These are termed illusions because they create an effect where 3D media appears to be floating in the air magically, that 19 creates a wow effect on the viewers, capturing their attention, and thereby serving the purpose of the marketing campaign for the businesses.

Some prominent techniques that are being used for creating this 3D projection iusions are . 15 1. Pepper's ghost projection technique, : 2 High speed rotation fans with LEDs on their blades, 3. Projecting 3D media using high-definition projectors on a super fine mesh structure that appears anaparent to tha naked eye, 4. Projacting 30 media on mist layers in ain

In a nutshell, there is always some projection material suspended in the alr which looks almost transparent, and the 3D media is always yrojectad on it, which makes the 3D media appear floating in the thin ai, This is priroarily the reason tis called an

Hlusion becauss the 3D media is made to appear floating in the air. This iusion is also termed as a hologram due fo ifs floating In the air nature,

Pepper's ghost projection technique has been used for a long time to create a 3D projection display Hlusion effect. In this technique, the 3D media content is projected on an inclined projection material, The inclined projection material could be a glass with special optical coatings to create the holographic floating effect, foil with optical coatings, mesh, or other similar materials mounted on the sides of some frame to hold it, The projection itself occurs from either the top or the bottom mounted electronic device screen or a display projector. When the light with the 3D content is projected from either the top /bottom, the inclined projection material reflects a pertain amount of fight and refracts a certain amount of light The amount of reflection / refraction is decided based on the optical coatings on the projection material, depending an the surrounding ambient ght and the other environments! light conditions, The top / bottom projection creates a floating 3D image effect of the projected 3D content that looks like a hologram, behind the inclined projection material, The biggest advantage of Pepper's ghost technique is the design of the display allows the combination of physical oblects placed inside the display {behind the inclined projection material) with the virtual 30 content projected from the top / bottom, ic craate a mired reality

JO anvronment to create a wow effect. There are different versions of 3D projection displays that exist in the market using Pepper's ghost projection techninus,

Almost all of these are focused on business disnts for business use cases, where a large sized display ís used for various types of publie engagement during events, trade shows, museums, ele. The casing for these displays typically is designed such : that tt can be tansporled in a completely Duif unl or collapsilds structure that is assernblad on the site, Tis casing materials could be metal, plastic, wood, ste.

Those displays weigh in tens / hundreds of kilograms, are bulky, need spacial flight cases for safe iransporiation, and arg very expensive lo buy or rent costing a few 28 thousands to tens of thousands of Euros easily. Some prior an patents using

Pepper's ghost technique for 30 projection displays are WO-2011045437A1,

WO-2008070341-A1, EP 2808833 Al and US848219282, These patents describe different usages of Pepper's ghost projection technique using different types of display casing structures and designs. '

While most of the current 3D projection displays are designed and optimized with a focus on the business market use cases, they can have applications and usages in the consumer market as well, if done with the right hardware and software combination approach to make them consumer friendly. The challenges faced in the 3¢ display design for the consumer market are completely different as consumers are focused on quality, affordability and value for money primarily, while avaitabifity of software content ecosystem lo use the displays repeatedly with ease of uss also becomes critical for thelr success. These challenges require a rethink from soratoh af the entire design of these displays as t's not just a matter of minor tunings or scaling the hardware down or up, a3 optical products are incredibly sensitive to such changes affecting their visual quality immediately, as any sub-optimality immediately shows up visually, making these displays very challenging in practical implementations comparad io their on paper theoretical designs that might look simple in theory, The ultra~compact, lightweight, portabla, affordable, shipping friendly, software ecosystem supported, high quality 3D media projection display we introduce in this document primarily addresses all the related challenges.

Technically, the challenge with 3D projection displays is, their relatively large size which may result in increased logistics and shipping costs which is a deal breaker in ine price sensitive consumer market. Aspecis of the technical solutions described herein address this technical challenge by a new fiat packaging design that fits in a compact letterbox parce! alze which ts maximum of 3G mijlimeters thickness, thereby drastically reducing the volume and in tum the shipping costs. The size is called letterbox parcel because ft fits through the opening in the letterboxes for consumers at their home, indicating the compact parcel siza. .

Another technical challenge with 30 projection displays is the usage of the right material for the device casing which in tum may affect the quality of the visualization due to various factors like perceived contrast, backlight Hlumination spread, and perceived depth, Aspects of the technical solutions described herein address this technical challenge by using a high-ruality cardboard with deep contrast or similar materials that allows the casing fo be made jn a design that gives a better control on various visualization environment parameters due to the right material choices, . Another technical challenge with 30 projection displays is thelr weight and related logistics problems such as increased shipping costs due to ingrease In weight,

Aspects of the technical solutions described herein address this technical challenge by using cardboard or similar materials that are not heavy, yet vier rigidity and strength to the display casing without increasing its weight and costs of shipping.

Anuther technical challenge with 3D projsction displays is the lack of flexibility to accommodate a range of different electronic device screen sizes with quick setup times.

Aspects of the technical solutions described hereis address this technical challenge by providing a design that can accommodate a range of differant slecironic device screen sizes in smartphone form factors, with an easy fo use setup, Anather fachnical challenge with 3D projection displays is they need to be provided with a source of power supply to power the device which often may involve dangling cables around the device and dependency on the power supply. Aspects of the technical solutions described herein address this technical challenge by providing a rechargeable LED light mechanism with a fow hours of battery life and easy acceasibility for recharging and replaceability. Another technical challenge with 3D projection displays is the ability to control the backlight spread inside the display.

Tha LED light positioning mechanism of the present disclosure allows dynamic adjustment to spread light inside the display to control backlight spread thereby allowing better control on lighting conditions inside the display for different ambient! fight environments.

The display device as cited In this art offers best value Tor money, Competitive products do not offer the range of content solutions that go with this product io be able to use this display fortis best abilities, so wo offer both hardware and software closed ecosystem and allow users to use tools to create thelr own simple 3D contant further that is super affordable.

Letterbox packaging is designed so that the packages can slid through the hole for receiving packages in a letterbox at consumer houses. The 30 mm thickness is @ packaging size that may offer an optimal choice for volume as the shipment prices differ based on the volume of the packaging and different geographical regions always have a parcel size that costs. much lass to ship dus to iis compact natura,

Pricing increases once the thickness / volume crosses a threshold. 30 mim ix a alee commonly used in EU countries for the cheapest shipping price for parcels as prices rise sharply once this threshold is crossed. Other geographical regions have similar sizes thal are super compact and offer cheaper shipping costs, 30 mm as a reference size ensures adherence to such compact packaging in terms of volume for minimum shipping prices overall around ine world for consumers,

Figs. 5-8 are diagrams ilustrating the component paris of the display {1} of Figs, 1-3, according tn an implementation of the present disclosure, Assembly of these component parts from Figs. 5-8 to produce the display (1) is illustrated further in Figs. 8-18.

Fig. 5 ilustrates a first structural component thal may be used to form the display {1}.

The structural component may be referred to as the display walls, Fig. § shows the walls {2,4.5) and the top enclosure wall (2) of the display (1) in its flat design, which forms the outer casing of the display (1). The top enclosure {2} may be hingsably attached to the wall (3) in the first configuration. The dashed lines indicate the place where the fold may take place to bend the material to make it in the upright position. ) The folds may be made on the dashed ines hetwesn parts (3) and (4) and belween parts {4} and (8) at 90 degrees clockwise and 90 degrees anticlockwise respectively, such that the part {3} becomes the left wall and the part (8) becomes the right wall in an upright position, while the pan {4} becomes the base wall. When materials such as acrylic, plastic, plywood may be used Instead of cardboard, the dashed lings may be used as a position ts cut the material instead of folding it and the individual cut parts ther may be adhered io each other lo create the display walls, The gray stripes in the drawing shows the position of the paper glue taps that may be used during the assembly process of these components to foro the display (1), when the display {1} casing material is cardboard, For ciher materials anmopriate adhesion mechanisms may be used to assemble the components together to form the display {1},

Having & permanently fixable assembly mechanism using the paper glue tapes ensures & super compact design due to minimal display casing material thickness {at thes most 3mm In our case), as there is no need of grooves and extrusion in ine display casing material Io detach the display casing after assembly. Once grooves and exirusions are used as a prime mechanism to coups the components a thickness of at least 8 mm is required for the display casing material io ensures sufficient rigidity and strength Tor the groove and extrusion structures, which further increases the thickness of the display casing material, making the packaging bulky and directly affecting the end costs for consumers, making the and product expensive, Hance, this non-detachable 30 media projection (ableton display (1)

enabled to fit into a 30mm packaging, made using paper glue tapes may provide lightweight, easily portable and cost-effective option fo the consumers.

Fig. 6 fHlustrates a second structural component (8) along with other component paris (12.13,15) that may be used lo form the display (1) The structural component may be referred tp as the cage structure (8), which may be used to place the electronic device screen that may play 3D media which may be projected cn the projection material (17), to create 3D simulated holographic visuals inside display (1). The cage structure comprises of front, Jef, right {84,3d,8e) flaps respectively, which may be folded on the dashed ine by 96 degrees in the upwards direction, to make the flaps become side walls of the cage structure. The gray stripes in the drawing shows tha posilion of the paper give tape that may be used during the assembly process of this component when the material is cardboard. For other materials an appropriate adhesion mechanism may be used,

Fig. also shows a diagram of a plurality of L shaped strips that may be used as a support mechanism to keep the front wall (8a) in the upright position. The plurality of

L shaped strips (12) may be adhered between Ief (8d) and front wall {8a} and the olurafity of L shaped strips (13) may be adhered between the right (Se) and the front wall {8a}, to form the support mechanism lo have the front wall (8a) stay inthe upright position to form the cage structure (8). Any suitable mechanism may also be used inplace of the L shaped strips fo ensure the side and front wall of the cage structure {8} stays in an upright position after folding 80 degrees in the upwards direction, Due to bending, there are Immense stesses in the upright position front wall (82), and the left (3d) and right {Se} walls ta hold them all together and the niuraliy of L shaped strips {12,13} form an 15 important structural innovation to hold the cage structure § with fis walls in an upright position. This might look like a simple structure but holds immense importance in the casing structure integrity to kesp the cage structure (8) attached to the display casing walls (3) and (5) without any visible misalignments and excess big gaps from the front side of the display fo add to the overall aesthetics of the display look for consumer satisfaction and ease of quick hassle-free assembly during the casing constructions.

Next is the description of the slectronin device zoreen fitting mechanism i the zege structure {8). The center hole in the cage shucture {3} may have only a small bezel around it, so that electronic devices of different screen sizes may be placed in the cage structure (8) using a screen size adjustment mechanism that we describe next.

A plurality of layers of components {15} made fram a thick paper like material may be used to create an adjustable electronic device screen fitting mechanism to be used in the vage structure (8), to mask the center hole to fit different screen sizes.
