 Hi. So please introduce yourself. Hi, my name is Dr. James Allen. I work with EMD Electronics, developing liquid crystal and polymerized liquid crystal based materials. So where do we see you right here? So what we're looking at here is a full color waveguide using a polarisation volume holographic technology. So what it utilizes is it's a layer of glass and on top of that we have a photosensitive alignment layer and then on top of that we put a layer of liquid crystal which is then polymerized to give a solid film and that can be used to create diffraction gratings or diffraction lenses. So yeah, what we're offering really is the materials to enable this technology. Waveguides? Yeah, to enable waveguide technology, to enable ultra thin lenses for AR and VR. We're not making the waveguides ourselves, we're making the materials and we're making them available to companies to develop and improve their their existing portfolio. So waveguides are very intricate. There's some very small details in waveguides? Yeah, exactly, yeah. So this uses gratings with very very narrow pitch. Yeah, so one of the advantages of this technology compared to say other grating technology like surface relief gratings, SRG, is this is a solution processable. So the intricate details come out of the photo alignment process. Is it possible to avoid the kind of like reflections that go in different directions? So it's definitely things that people are working on, like we're not trying to produce a waveguide. This is a very simple waveguide design and it's got a relatively limited field of view as a result of that. And yeah, and you see some of these rainbow reflections. It's something that people in the industry are actively working on to to improve upon. And yeah, as I said, these materials enable lots of different waveguides. With the same material we're told that fields of view in excess of 50 degrees is probably possible and then we're working to still improve these materials to give even larger fields of view. Nice. And what do we have here? So this demonstrator uses the same technology, also a polarisation volume hologram. This is also referred to as a pentraton and berry grating. So what we see here is you'll see two images and neither of those are actually the true size of the image below. If we slide in one of these, slide this in, this is moving just polarisers. So circular polarisers, left and right-handed polarisers. And what that does is it selects for a magnified and a demagnified image. So if I slide out one polarisers and slide in the other one, you'll see this image is now small and then we move back and then the image is enlarged. So it's actually the same grating. It's the same grating doesn't move, that's in the middle. And this is about an ultra-thin layer. It's less than, well, it's approximately one micrometre thick in that order of magnitude. And it allows you to create lenses that are ultra-thin and lightweight. Nice. How does it come with these that, let's say, a company like Leica has and making lenses for cameras? It's just a much smaller version of that? Well, so obviously those are very precision, very engineered lenses. So this can be varied and is very customizable. So for example, the focal length is varied by changing the grating pitch. And we've been working hard on reducing the chromaticity of the lenses. So there's all the same consideration with these kind of lenses as you have with traditional lenses. But yeah, the advantage really is that they allow for ultra-thin, ultra-light weight. Some people have used these types of lenses, not specifically to create electro-actuated lenses. So you can use these, a series of these and then you can use switchable wave plates in order to achieve different focal lengths. When I look at the market of AR, VR, what's happening, are you the leader in supplying all these devices? Well, we're one of the leaders in material supply. So EMD, electronics, we have been for a long time a leading provider of liquid crystal materials to the display industry. We're also now doing OLED materials to enhance that portfolio. And then these technologies actually derive from our portfolio of materials we call reactive mesogens. And so these reactive mesogen technologies have been used for a long time in the display industry as corrective films. So anti-reflection films in OLED, viewing angle corrective films in LCD. So yeah, so we're a leading provider of materials and allow a lot of companies to realize their designs. And the mesogen has nothing to do with hating women. Hating women. No, not misogyny. No, mesogen. So mesogen refers to the rigid part within a liquid crystal which dictates its alignment director. So yeah, that's mesogen, not misogyny. Nothing to do with that. Cool. But it's so awesome. It's fascinating to get a peek into the world of materials that you talk about. Yeah, exactly. Because it must be a very exciting field. Yeah, exactly. Well, a lot of stands around here, you know, everything. I think we have a sign somewhere up that says displays start with us. And I think that's very true that, you know, one of the underpinning technologies to all displays is the chemistry and the materials that make these technologies come alive. And these have to come from somewhere. And yeah, it's one of our primary focuses is allowing technology companies to realize their ambitions. It's fascinating. I'm just a YouTuber, right? So I don't really understand. It's fascinating to understand. To learn about the, you have some kind of really nice mixture of materials, you put some electricity and boom, it looks awesome. You can create a wide variety of effects. Yeah. So that's pretty awesome. Okay. But thanks a lot. No problem at all. So here, the display week, there's a bunch of 8K displays, there's 4K 120. And all these new TVs can come with HDMI 2.1. And there's a whole bunch of updates that I'm going to be filming at the Computex 2023. With the HDMI licensing administrator, which are organizing all the display makers, the cable manufacturers, and making sure that they are compatible with each other. There's a stable performance, there's no interference. And there's a smooth 8K future with 48 gigabit per second support. And there's the whole infrastructure for certifying, for testing, for making sure there's no interference with the Wi-Fi and Bluetooth and stuff that people have. So thanks a lot for watching.
