[0002] The disclosure generally relates to mobile displays and more specifically, it is related to a mobile, low profile, light-weight hazard-free display system.

[0003] As is widely known, to present goods for sale to the public in a store setting or other private or public venue or establishment, merchants use stationary plastic, wooden or metal displays, walls, surfaces, tables, shelves and racks having surfaces on which goods offered for sale may be displayed to inform customers and passers-by about product and service offerings. Another known display system the stationary pep or slotted board display wall, surface, table, shelf, and rack wherein a variety hangers, such as hooks may be positioned to assemble a wall or surface of hangers to orderly position goods for sale and to enable easy access to such goods. Such static display racks may include adjustable shelving or surfaces to display a variety of goods and services and allow for individualized positioning and placement of such goods. Moreover, such static display racks may enable placement of static marketing and advertising materials, such as posters and flyers; which may be positioned approximate such goods. Still further, such static display racks may include an audio or video display, such as CRT, TV, LCD monitor, positioned within the static display racks to enable a customer positioned, right next to the display, to see and hear marketing advertising content relating to the sale of the goods positioned in the static display racks.

[0004] CRT, TV, LCD monitor, and like displays have many drawbacks: such displays are stationary or immobile displays due to their hazardous weight and tip over potential, and therefore must be enclosed in an immobile frame for support. Moreover, such displays have glass fronts or covers, such as CRT and LCD, and can cause serious injury when bumped or dropped resulting in an explosion or shards of glass in the viewing area. Furthermore, large displays having glass fronts and covers, such as CRT and LCD, are heavy, thick and bulky and are cumbersome or difficult to move easily and quickly about the merchant's venue, especially during product liquidations and mark downs or seasonal or theme reconfigurations or changes, wherein the footprint of the store is significantly altered or redesigned. Still further, large displays, such as CRT and LCD, consume large amounts of power and generate heat in the process making them expensive to operate and maintain. Yet, still further, such displays are not proportional in size to a viewer having smaller or partial sized avatar or digital mannequin images which fail to extend from the floor to up above the viewer; therefore, such images limit the viewer's experience of interacting with a full size avatar or digital mannequin. Such unnatural or partially sized avatar or digital mannequin images tend to reduce or limit the willingness of a customer to interact with such digital content; thus, reducing the displays effectiveness of informing customers and passers-by about products and service offerings, and answering informational requests.

[0005] In addition, large mobile displays, such as CRT and LCD, are in use for medical, dental and spa establishments where a CRT or LCD display, computer, printer, and AC power supply connection are positioned on or integrated into a table top or wheeled table top assembly. For example, a 46 inch LCD may be mounted on a mobile display rotated in portrait mode and a miniature scale image of a person may be displayed on the screen. In other applications, LCDs may be stacked side-by-side to create a larger image but create visible seams that distort and segment the visual image into areas or sectors. These bezels create significant disruption an interruption of the visual image as seen by the viewer.

[0006] CRT or LCD displays have drawbacks such as they utilize heavy hard, to move high resolution CDT or LCD displays with glass fronts or covers. Such displays can cause serious injury when bumped or tipped over resulting in an explosion or shards of glass in the viewing area. Because of this risk the table top or wheeled table top includes large, heavy frames and support structures to stabilize such displays causing the display portion to be several inches or feet off of the floor. Moreover, these large scale displays tend to be heavy, expensive to operate, not easily transported and set up, and are power hungry.

[0007] Furthermore, it is also known to place print material on external surfaces of vehicles, such as city buses and motorized trucks to publicly display marketing and advertising materials to inform customers and passers-by about product and service offerings.

[0008] Moreover, it is also known to incorporate a single capture device, such as a camera which is often positioned above or below the viewer to integrate external audio, still frames, or video content into the display system or display system content; however, integrating content, such as downward perspective or upward perspective from such capture device does not create a full size, proper dimensional or perspective image of the viewer. Rather such capture device captures a distorted perspective visual of a viewer or passers-by.

[0009] Lastly LCDs have been mounted in portrait mode having the long side of the LCD positioned vertically. This vertical LCD is mounted on a stand and placed on the floor of a retailer or other establishment. The problem with this vertical LCD is that they are not full person size. For example, the LCD may be 46-54 inches diagonally and any image displayed thereon will appear as an unnatural miniaturized person scaled to fit on the display. Moreover, LCDs have large frames around the border of the LCD causing the screen portion to be elevated off the ground giving the appearance of an unnatural floating image of a person displayed on the screen.

[0010] Therefore, it is readily apparent that there is a recognizable unmet need for a mobile, personsize (6 foot or more high 3 foot or more wide; personsize) display system and method of use that safely and economically functions to inform customers and passers-by about product and service offerings via rugged full personsize mobile, with the bottom of the display as close to the floor as practically possible, light weight, thin, battery powered display and; thereby, enables full personsize viewing, quick redesign and configuration changes to the merchant's establishment without the need for heavy moving dollies, skids and other moving equipment, or any special tools or special power requirements or power alterations to operate the mobile display system.

In addition, AC power supply system 60 preferably provides power to additional (shown three) regulator boards 52 configured to deliver constant voltage, current, and/or power to media player 42, scalar board 43 and an electronics device or control board, such as sending card 45 of media player 40.

[0102] Referring now to FIG. 7.1 by way of example, and not limitation, there is illustrated an example embodiment of one of the one or more display sub-assemblies 54 unattached from sub-frame 71 shown connected via power and data connection, such as DC cable assembly 51 and data ribbon cable 49. Preferably, one or more display sub-assemblies 54 may be easily switched out by disconnecting an old or existing one of one or more display subassemblies 54 and reconnecting a new one of one or more display sub-assemblies 54 wherein such connection(s) are between one of one or more receive cards 46 shown in FIG. 4 and/or DC cable assembly 51 between one of one or more regulator boards 52 and one of one or more display sub-assemblies 54 to provide the necessary power and commands to make the light emitters 72 of one or more display sub-assemblies 54 emit light in a desired manner.

[0103] Preferably, one or more display sub-assemblies 54 includes one or more pixels or cells, such as light emitters 72 including light emitting diodes (LED) or other light emitting technologies, such as, by way of example and not limitation, liquid crystal display (LCD), backlit LCDs, electroluminescence, plasma tubes or cells, or plasma display panels (PDP), organic light emitting diode (OLED) and the like (light emitters 72) In an exemplary embodiment, light emitters 72 are preferably sized relative to pixel gap d1 so that the gap line between light emitters is less noticeable while still providing a desired resolution for sub-assemblies 54 and flat panel display 18. For example, in the exemplary embodiment shown in FIG. 7.1, each light emitter 72 of one or more display subassemblies (preferably 7×3=21 spaces shown) may include P 4.0 mm DOT Matrix Nixel 64×32 resolution LED or other light source known to one of ordinary skill in the art. Preferably, light emitter 72 are positioned distance d1 between each neighboring light emitter 72 configured as an array or matrix of light emitter 72 to form each of one or more display sub-assemblies 54.

[0104] It is contemplated herein that distance d1 between each neighboring light emitter 72 may include 1 mm to 10 mm depending on the desired resolution, viewing distance and acceptable price point for flat panel display 18.

[0105] Referring again to FIG. 7.1 by way of example, and not limitation, there is illustrated thereto sub-frame 71 of flat panel display 18. Preferably, inner panel, surface, frame or cross bars, such as sub-frame 71 supported by support structure 14 shown in FIG. 1 and FIG. 2, and further includes vertical members 71A and horizontal members 71B configured to cross one another forming a lattice framework to releasably affix each of one or more display sub-assemblies 54 thereto. Moreover, each of one or more display sub-assemblies 54 is releasably affixed to vertical members 71A and/or horizontal members 71B by magnetic connection or the like. For example, if vertical members 71A and horizontal members 71B are formed of steel or other ferrous material then magnets may be affixed to the perimeter of each of one or more display sub-assemblies 54 to releasably affix each of one or more display sub-assemblies 54 to vertical members 71A and/or horizontal members 71B. Alternatively, if vertical members 71A and horizontal members 71B are formed of aluminum or other nonferrous material then magnets or the like may be affixed to vertical members 71A and horizontal members 71B and magnets or the like may be affixed to the perimeter of each of one or more display sub-assemblies 54 to releasably affix each of one or more display sub-assemblies 54 to vertical members 71A and/or horizontal members 71B.

[0106] In an exemplary embodiment, light emitters 72 are preferably spaced apart relative to pixel gap d1 between light emitter 72 such that pixel gap d1 is less noticeable to an observer.

[0107] Referring now to FIG. 7.2 by way of example, and not limitation, there is illustrated an example embodiment of flat panel display 18 having one of one or more display sub-assemblies 54 positioned therein. Preferably, each neighboring assembly positioned therein flat panel display 18 is configured having a space therebetween, such as sub-assembly gap d2. In a preferred embodiment, sub-assembly gap d2 between neighboring sub-assemblies 54 is preferably approximately equal to pixel gap d1 shown in FIG. 7.1, between individual light emitters 72 shown in FIG. 7.1, of one of one or more display sub-assemblies 54, such that pixel gap d1 and sub-assembly gap d2 is less noticeable or seamless to an observer.

[0108] In an exemplary embodiment of one or more display sub-assemblies 54, light emitter 72 are preferably of a size relative to the pixel gap d1 to make the pixel gap line less noticeable to a viewer. For example, the pixels may be of a size relative to the size of pixel gap d1 so as to provide a display of a desired resolution in which pixel gap d1 is not as pronounced or distracting to the viewer. Moreover, sub-assembly gap d2 is preferably of a size approximately equal to the pixel gap d1 to make sub-assembly gap d2 less noticeable or seamless to a viewer. This relationship and sizing may depend on a number of factors, including, but not limited to, viewing distance, contrast ratio, brightness, and viewing environment.

[0109] One problem with prior art displays is that sub-assembly gap d2 is of such size that gap lines are visible in the resulting display which is distracting to a viewer and renders an image of poorer quality. It is contemplated herein that if sub-assembly gap d2 is to close or narrow then a bright line may appear between a perimeter row of light emitter 72 and if sub-assembly gap d2 is too far apart or wide dark line may appear between a perimeter row of light emitter 72, thus such gaps would be noticeable to and distracting to a viewer. Alternatively, because there are no light emitters 72 to produce light at sub-assembly gap d2, the gap may appear as a darkened area of a display, referred to as a “pixel gap line.”

[0110] It is contemplated herein that if sub-assembly gap d2 is equal pixel gap d1 or if such gaps vary by no more than +/−20% from equal (d1=d2) then such gaps are preferably less noticeable to and distracting to a viewer.

[0111] Referring now to FIG. 8 by way of example, and not limitation, there is illustrated an example embodiment of a cross section 80 of one of one or more display sub-assemblies 54 shown in FIG. 7.1, configured with plurality of light emitter 72. One problem with prior art displays is individual light emitter 72 are raised above the outer surface of flat panel display 18 and when bumped or pushed on such individual light emitter 72 would break off or lose connection to power and command circuitry. In an exemplary embodiment, a plurality of light emitter 72 are preferably configured or formed on a rigid substrate that serves as one of one or more display sub-assemblies 54 of flat panel display 18 shown in HG 7.1.

[0112] Preferably, light emitter 72 may include subpixels 85 which may be divided into groupings, such as groupings of three subpixels 85, to form pixels or light emitter 72. For example, subpixels 85 that emit red 85A, green 85B and blue 85C light may be grouped together to form an RGB pixel light emitter 72. Preferably, light emitter 72 may be positioned in a matrix formation as “chip on board” printed circuit board (PCB) 87B configured with pixel gap d1 therebetween adjacent light emitters 72. In order for flat panel display 18 to be configured as rigid surface, tough face or uniform surface that resists abrasion and is easy to clean, each light emitter 72 is preferably positioned in a bowl or divot, such as cup 82 formed in upper layer 87A. Preferably, one or more cups 82 are encapsulated with plastic or transparent filler to allow light emission through the substrate or to blend RGB light or the like such as optical epoxy 86. Preferably, upper layer 87A and printed circuit board (PCB) 87B may be held under pressure while optical epoxy 86 cures. Moreover, printed circuit board (PCB) 87B is preferably shown with integrated circuits such as 8×8 drive circuit 89 and COM circuit 88 connected via power and data connection, such as DC cable assembly 51 shown in FIG. 7.1, and data ribbon cable 49 shown in FIG. 7.1. Preferably, printed circuit board (PCB) 87B is configured to connect drive 89 and COM 88 and one or more light emitter 72 to emit light in a desired manner on one of one or more display sub-assemblies 54. Additionally, the light emitted by light emitter 72 may be converted or filtered to provide the desired light output; for example, the pixels could be formed of blue LEDs that are filtered or are color converted and filtered.

[0113] It is contemplated herein that cross section 80 may be provided in other shapes and arranged to provide one or more display sub-assemblies 54 of an appropriate size, shape, and/or contour to provide flat panel display 18 with a desired display configuration. Moreover, flat panel display 18 may include flexible substrate printed circuit board (PCB) 87B and/or one or more cutouts or bend points in pixel gap d1 and/or sub-assembly gap d2 shown in FIG. 7.1, and the greater the number of bending points that can be provided the greater the flexibility or curvature of flat panel display 18. For example, if it is desirable to provide a greater amount of flexibility or curvature in one direction of flat panel display 18 than another then cutouts or bend points in pixel gap d1, sub-assembly gap d2, and/or one or more display sub-assemblies 54 can be shaped to provide such flexibility by arranging a larger number of flexible gaps in the one direction than the other.

[0114] Other arrangements, such as by way of example and not limitation, include a mono-color display in which all subpixels 85 or pixels emit the same color light. Moreover, subpixels 85 may have different properties in order to provide desired properties for light emitter 72. For example, light emitter 72 may comprise red 85A, green 85B and blue 85C subpixels 85 that together form an RGB pixel. The intensity of the individual subpixels 85, red 85A, green 85B and blue 85C, can be manipulated to provide light having desired characteristics, such as a desired light color or brightness.
