 So we're here with a FOV3D here at SID Display Week and we're looking at your special display right here. So hi, so who are you? I'm Thomas Pernitt, I'm a founder of FOV3D. And what are we looking at here? This is a true light field display so it's a full parallax perspective correct light field display. So is it something that can be viewed with the camera or need-wise? No, no, you can do it with the camera. So what am I looking at right here? Well you're looking at a pyramid moving so we're animating a light field in near real time. How's it possible that I can see all these angles by moving around? Well because we're projecting all those angles. We're projecting the light that would reflect off that object if it was actually there. And so it's how does that work? How do you do this? Well you're not actually seeing me directly right? You're seeing light reflecting off me and impinging on the lens or your eye. Instead of having that light reflect off me if you just project that same ray attribution onto the eye or onto the camera you'll get a perspective correct image. I don't understand. So do you have a graphic and show us what is going on here? Right, so what you're looking at here is, we call it a hodl for holographic element, but you can consider it a directional pixel in that depending on how you're looking into that micro lens you're seeing a different ray. And the idea is when you have an array of these hodls each having distributing the correct ray information when you look into the display you'll see a 3D aerial image. If you're familiar with a light field camera this is sort of the inverse of the light field camera. What's a light field camera? Well a light field camera captures the direction and intensity of light in a field so to speak and so a light field display just the inverse of that. How many angles or you know it seems there are different angles? So there's 12,000 unique views that this display is capable of doing. 12,000? From every different angle. From every different angle. But it's like an area where it's too much right? Yeah you're outside of the projection freshman. So how big is the projection area? It's a 90 degree projection freshman. And so is this kind of like the ultimate hologram? Yeah it's a holographic display like you see would see in Star Wars so that is the idea. Since when are you working on this? Well I've been working on this kind of technology about 15 years but Fovey's been working on it for about three. It's your company? My company. So what's next? What's the market? Well what's next is to make larger light field displays color. Markets are military, oil and gas, medical, maybe e-sports visualization. Anything where you want to collaborate over complex 3D data? And what are those kind of like squares? So you're looking at 20 4k OLEDs that are all tiled together so 20. Yeah so they have it. Yeah it hasn't been color balanced so you're looking at the non-uniformities of all those those OLEDs. As because there's a bezel less small OLED displays? Right. But they're all 4k 4k 4k? That's correct. There's nothing inside this box right? Well there's a bunch of drive electronics that manages the signals to those OLEDs. It's just flat is it? Well it looks like there's something in there. No yeah it's flat. The photonics and optics is very very narrow. This is all drive electronics down here. And what's different on this one? Different micro-lens have a lower spacial resolution? But it has a lot higher angular resolution. So this display can project something taller but with less detail and that display can project something with more detail but less height. Taller? Yeah. Because people have been talking about wanting to do holograms for a long time right? Yeah so why isn't it like everywhere yet? Well it's pretty hard to do. This is actually 108 megapixels or mega rays in this little box and so it's quite a phenomenal challenge to you know control all that light and compute all that light. 108 megapixels? Like a 4k is 8 megapixels right? So you have a bunch more. Yeah and it's 108 megapixels in a 9 centimeter by 9 centimeter square area. How do you get those tiny 4k displays? Well micro OLED actually makes these 4k displays. Like micro displays? Yeah they're 4k micro OLED displays from micro OLED. They're in France. And they fit right here? Yeah. We had to tile them together that was complex. There's no bezel? Well they have a small bezel so there's a there's a relay optic on top of them. You're lensing them together so there's no scene? That's correct. And how do you make a huge one in color? Is it just going to be the same? We just tile more of them. Yeah. Just more of them? Yeah. Do you need to drive more of them? You need a bigger chipset or something? You need more of everything. More OLEDs, more driver boards. Is there FPGA in there? There's six FPGAs in that box. The secret rich ones? Yeah there's some secret sauce in there but there's five driver FPGAs and there's another FPGA that sort of manages them all. So at some point we all have holograms at home, right? That is the idea. How soon is that? Like a couple years? Ten years probably. You'll start seeing them in your homes. They always say ten years, right? That's what this joke is about. Everybody here says two years. We're saying ten. You're saying ten. But so ten years everybody has one? I would like to see them proliferated in ten years. Then it feels like somebody is in a room or what does it feel like? No you'll get an experience like this where you can sit around a display and watch like a football game in 3D with your friends. But you could also feel like your friend is in the room right there? I don't think we can get that that level of fidelity in ten years. I view it more of, you know, maximizing the 3D fidelity of an image volume about six inches deep. So no matter where I position the camera, there's always an image. That's correct. A perspective correct image. Just like in real life. Everywhere. Everywhere within the projection freshman. Because there's all these like glasses-free 3D space. This is a true glasses-free. Every time you move it's like jumping. Yeah, so that has those view zones. This doesn't have zones. This projects a field of light, a perspective correct light. So how long have people talked about holographic displays? 30, 40, 50 years? Yeah, definitely. But why is it not yet? Well it is kind of hard to put these things together. They didn't have 108 megapixel displays back then? That is true, yeah. It's still hard to make them. Yeah. So what if a huge company comes by and says hey we want to speed it up? It's all about money now. I mean the whole reason that we're here is to socialize that this is not science fiction anymore, right? You can make these displays and you know there are some challenges but they're all addressable. And so you know we had some pretty good responses from industry people that could solve a lot of those problems whether it's compute or photonics or optics. What do you need to solve? Without saying too many secrets. I think that compute is a challenge and I think being able to preserve the detail of all these rays when they're angrily distributed is also a challenge. So those are the two fundamental things that need to get solved for more commercial adoptions. Where is it just yellow? Brightness. Brightness can color pixel density. So if you had all colors it'd be hard to make it look like that? Well we took a color OLED and we doped all the subpixels to be yellow-green and we picked yellow-green because it was brighter that way. But you want to have full color? Yeah we can do full color. You can. Where are you based? In Austin, Texas. And so what's next? What if some of the industry people came over and said we really like that we want to have them? Yeah so we can make I think you know with the right investment we can make mobile displays, we can make large tabletop displays and anything in between. You know I think the architecture is the same it's just where you really put your engineering dollars. You know this red company? Red phone. How does that look? It looks pretty good actually. But what is that technology? Well it's similar to this and I haven't seen too much of it but it's a single-user you know light-filled phone that produces a 3D aerial image you can't you kind of hold it out here and I think it looks pretty good. And are the companies working on the holographic stuff? I think but you know that company is lay and I think they've done a good job on the mobile stuff. I don't know if there's any buddy else who's got a full-on you know desktop light-filled display like we do. I think Samsung has had one in their booth in the past years but I haven't seen it this year. All right cool so looking forward to that at home right and everywhere. Yeah yeah yeah yeah. A couple years. All right.
