Description:
The present application claims priority from U.S. provisional application 63/276,466 filed Nov. 5, 2021 entitled Dual Sided Display by same inventor Cole Franklin, the disclosure of which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention is in the field of digital displays. 
     DISCUSSION OF RELATED ART 
     A variety of different transparent and dual sided displays have a direct or projector system. 
     SUMMARY OF THE INVENTION 
     Clear displays are used today mainly as name signs or on trophy but there will be a day when movies can be watched on a transparent display. There are some companies developing transparent displays based on transparent organic LEDs. A competitive high technology effect utilizes advancement in projector technology with much less manufacturing complexity. The manufacturing process for this technology has a low carbon footprint compared to what is currently on market. This novel display can disrupt the viewing market as people enjoy together images, movies, and projects in a more collaborative and futuristic way. Modern display technology and clarity can be achieved on glassy and transparent media using a d) short throw projector when a) combining photonic particles and b) light diffusion creates a standing wave that captures visible light. This combination we have shown to retain and refract nearly 80% of light projected at it and can be achieved with various media including glassy, clear epoxy, clear silicone and other transparent or translucent material. Additionally, adding c) angular tapering to the pocket where the photonics particle sits improves the daytime brightness minimizing the ambient lights effect on the image. Utilizing advanced texturing with layering in photonic particles on various substrates can create pixels that can collect and then retransmit or re-broadcast red, green, and blue light when a projector emits its image onto the substrate. Texturing controlled visible wavelength reflectors in glass with optical wells where the wells have angled walls from 30 to 90 degrees depending on level of ambient light that are between 1-30 ums with photonics particles in the range 300 to 800 nm would capture any image projected to it and have the desired effect. 
     The substrate forms pixels through forming a matted finish that scatters and diffuses the light at the surface combined with photonics particles in these pixelated pits from the matting process then captures the light into the pixel by forming a standing wave with the photonics particle that acts like the antenna for the pit forming a pixel. There is no applied power, only an applied and projected image from a projection lamp preferably in the form of a short throw projector as this allows for all the components to be housed in the same box under or along the side of the substrate being illuminated. 
     A dual sided display includes a display projector. The display projector includes a lamp and a display projector image. The display projector image has pixels and the pixels produce light as light rays. The display includes a display panel that has an upper edge, a lower edge, a left edge and a right edge. The display panel is formed of a substrate that is translucent or transparent. A display panel first viewing surface is formed on the first side of the display panel. A display panel second viewing surface is formed on the second side of the display panel. The wherein the display panel first viewing surface is parallel to and opposing the display panel second viewing surface. The display panel has a thickness. A displayed image is displayed on the display panel first viewing surface and the display panel second viewing surface simultaneously. The display panel is oriented to the display projector such that the light rays are projected at an acute angle of less than  45  degrees onto at least a portion of the display panel. 
     Optionally, the display projector is preferably mounted to the base. The display panel is mounted to the base. A first retainer can be mounted to the base and also be mounted to the display panel. The upper edge, the lower edge, the left edge, and the right edge are preferably frameless. The display panel preferably has a frameless upper edge, a frameless lower edge, a frameless right edge, and a frameless left edge. 
     The light rays are a group of light rays and include an upper light ray, a middle light ray, and a lower light ray. The upper light ray contacts the substrate and reflects from an upper tip into an upper pocket. The middle light ray contacts the substrate and reflects from a middle tip into a middle pocket. The lower light ray contacts the substrate and reflects from a lower tip into a lower pocket. The upper pocket produces an upper pixel of the displayed image. The middle pocket produces a middle pixel of the displayed image. The lower pocket produces a lower pixel of the displayed image. The display panel has a display panel surface roughness. The display panel has an upper region and a lower region profile. The display panel has an upper angle that is less than 30 degrees, and a lower angle that is approximately 45 degrees.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As seen from a top view of the present invention, the present invention has a base formed as a stand retaining a transparent substrate that does not have a frame. The transparent substrate can be a fresnel lens for example. The stand is mounted with a short throw projector underneath the stand. A pair of speakers can be integrated to the stand. The transparent substrate is aligned to a midline of the stand. 
     As seen from a front view of the present invention, the transparent substrate is generally rectangular and supported by the stand. 
     As seen in a perspective view of the present invention, the  50  inch stand supports a transparent substrate that when lit can be seen from both sides. 
     As seen from a side view of the present invention, light rebounds within a pocketed portion of the photon particle. Light is diffused through the pocket. The pocket can be formed in a regular pattern with the diffusion from the pocket at an angle that captures light and reflects it into the substrate, where each pocket is formed as a prism tip. 
     Unlike a regular fresnel lens where light is being focused from an angled path to a straight path through the lens, the present invention has the light focused from an angled path to a pocket, or a space between the prism tips were it reflects multiple times in all directions to allow double-sided viewing. 
     As seen in  FIG.  1    the substrate has an upper tip, a middle tip, and a lower tip. The lamp passes through an LCD display that passes through a focusing lens and lands on the substrate. 
     The upper light ray bounces off the upper pocket and rebounds within an upper pocket underneath the upper tip. The rebounding length decreases with each successive rebound. This generates an upper pixel display. The lamp is configured with discrete pixel display matching the pocket locations. As the light rebounds within the pocket, the translucent material around the pocket creates one pixel of display. The upper pixel corresponds to an upper light ray pixel on the LCD display. 
     Similarly, the middle tip receives a middle light ray which rebounds within a middle pocket and generates a middle pixel of display. The lamp configures the middle light ray so that it is aimed toward the middle pocket to generate the middle pocket display. The lamp can have a specific location calibrated to the middle pixel such as by a feedback focus mechanism where the lamp is connected to a processor and the processor views the display and automatically adjusts it for clarity by individually calibrating each light ray with a pixel on an LCD display that matches each pocket. The middle pixel corresponds to a middle light ray pixel on the LCD display. 
     Likewise, the lower tip captures a lower light ray which rebounds with successively shorter rebound length inside a lower pocket. The lower pocket generates a lower pixel of display based on the lower light ray. The lower light ray corresponds to a lower light ray pixel on the LCD display. 
     Accordingly, the tips are overhanging each other and overhanging the pockets underneath the tips like Christmas tree branches that overhang ornaments. As the pixels are illuminated on the substrate, they can be seen from both sides unlike a regular back projection television with a fresnel lens that is only designed to be seen from the front so has minimal backscattering. 
     The substrate can be a transparent glass board with matting on the side that collects the projected image. Optionally, an acrylic substrate can be used without matting where the acrylic has fiberglass particles which are poured over the acrylic substrate. The pockets can be relatively large such as  1 mm, or very small on the order of micrometers. For example, a clear resin can be applied over the substrate and the fiberglass particles suspended in the clear resin can be oriented randomly such that they provide pockets of clear area between them so as to allow a partially refractive media. The fiberglass particles can also create optical overhangs. 
     As seen in  FIG.  1   , the panel has a panel thickness  25  that has displayed pixels  20  on it. The displayed pixels can be displayed with or without a filler second substrate  25 . The substrate  63  of the panel has a display panel surface roughness  24  which can be smoothed by adding a filler second substrate  25 . Alternatively, the display panel surface roughness  24  has a plurality of concave pockets  30  that allow the light to be captured and retransmitted within each pocket. Each pocket can collect light and form a pixel. The pixels do not necessarily align to an array or regular structure. For example, though concave pockets  30  can include an upper pocket  31 , a middle pocket  32 , and a lower pocket  33 . The upper pocket  31  has an upper tip  41 , the middle pocket  32  has middle tip  42 , and the lower pocket  33  has a lower tip  43 . 
     The tips of each pocket reflect the light into the cavity of each pocket. The light bounces around inside of each pocket and ruminate each pixel. The pixel therefore has a pixel thickness  26  where the light is captured. 
     Discrete light rays  50  can be projected from a display projector  88  which can be a digital display projector having a display projector image  83 . The display projector image  83  is illuminated through a lamp  60 . The lamp  60  passes through an LCD  61  which has a display projector image  83 . The display projector  88  is a short throw projector which is at an acute angle to the substrate  63  which defines a vertical plane typically. The display projector  88  may project and upper light ray  51 , a middle light ray  52  and a lower light ray  53 . These light rays can be aligned to the upper pocket  31 , the middle pocket  32 , and the lower pocket  33 . 
     As seen in  FIG.  2   , the lamp  60  and the LCD  61  can be mounted on a base  64 . The display panel  73  can also be mounted to the base  64 . The base  64  may have speakers  70  including a first speaker  71  and a second speaker  72 . The display panel  73  has a first viewing surface  74  facing toward the lamp  60 , and a display panel second viewing surface  75  facing away from the lamp  60 . Thus, viewers can view the image on both sides of the display. 
     As seen in  FIG.  3   , the display projector  88  min. the display panel  73  and the display panel  73  can have a frameless upper edge  76 , a frameless lower edge  79 , a frameless right edge  77  and a frameless left edge  78 . The display panel first viewing surface  74  thus does not have any frame to it. This can provide a viewing experience where the image appears to be floating in midair. 
     As seen in  FIG.  4   , a larger implementation of the present invention may have a need for a frame. If necessary, a frame  65  for structure can be transparent so that it is not noticed by the viewer. The panel is preferably connected to a first retainer  66  and the second retainer  67  which are anchored to the base  64  at a first retainer anchor  68  and a second retainer anchor  69 . 
     As seen in  FIG.  5   , the first retainer  66  supports the panel above the base  64  and the base has a lamp  60  which projects upwardly toward the lower region profile  35  and the upper region profile  34 . The upper region profile  34  may have an upper pixel  21  with an upper pocket  31 . 
     As seen in  FIG.  6   , the upper pocket  31  and the upper pixel  21  may include an upper tip  41  and an upper middle tip  48 . Similarly, the middle pixel  22  can be defined between a middle tip  42  and a lower tip  43  which define a middle pocket  32 . The lamp  60  projects at a lower angle  81  which is less acute, and an upper angle  82  which is more acute. The display panel first viewing surface  74  and the display panel second viewing surface  75  of the display panel  73  preferably have equal luminosity.
