 So we had the SID display week and who are you? I'm Makoto Modani from Tokyo University Japan. And it says chair here? Oh yes I have just finished my job in this morning. Chair of an electromagnetic paper session. My field is electromagnetic paper. Like e-ink? Yes like e-ink or some electrochromic devices. And right here for example you're talking about some of this is one of the papers you published here the SID display week? Yes I will talk about this technology in poster session this afternoon from 5 to 8. The title is concept of e-time and its approach time. So what is the idea with e-time? This is a new application of e-paper. The expected application field is architecture, namely building components. So because it's just a segmented or? This is just a segmented display but our idea is to use these small tiles for large area by allaying any number of tiles. So I expect very large small area can be covered this tile. So black and white or different colors too? Till now only black and white. And then it will be for example this prototype you have an electronics here? Yes. To do what? Yes to control pixels. Switching on off? Yes. And the pixel size is very big one centimeter and pixel number is very limited hundred pixels in a tile but we suppose many big number of tiles will be allayed in a big space so the total pixel number will be enough. So then on the big space let's say Tokyo 2020 Olympics maybe? Hopefully. Then the whole stadium will be able to show amazing graphics very big. Exactly. Like the wall here right? Yes. And it will work. Yes it's one of my dream. How much is one? It's only a prototype but when is mass production? It's my future work but I hope this one tile is affordable. Maybe it's secret. Maybe it should be affordable that the stadiums will use a big wall every wall display. And I can say it's cheaper than using LEDs or using LCDs. How much cheaper? One half the price one half or a quarter. Quarter the price but also better in the sunlight if you have Olympics in the day and not in the night you want it to be beautiful during the day. Because this is reflective displays so under sunlight it can show its potential. Is it ink? Yes. And when you share of the reflective display what do you share? E-paper displays. E-paper displays. E-paper and flexible displays but this is not flexible. It's a rigid display. So does that mean it's also including like clear ink? Yes exactly. Clear ink and what do you think the latest with clear ink? Oh it's a very promising technology I believe. Exciting? Yes exciting. But I wish we could see the final product. We have to wait a little bit right? Yes. We have to wait wait. It's normal in the display industry right? To wait. But I hope in one or two years they will show their product on the market. The final one. The perfect color E-paper. How about the latest with E-ink? What do you think of the color E-ink? Yes they are doing very good job for color E-panel. So I hope in one year they will sell some color panel on the market. Right now the switching is a little bit slow right? But it's not so troublesome because there are many application fields. So billboard application or some information board application it is not so. But if you have the big stadium talk to a 2020 color E-ink then it will be strange. It will flash and people say why is it flashing? So you have to choose a good application. It's not a universal technology but very special technology for special field. Is it as good as a real painting on the on the wall? Yes I think so. It's like a museum piece. The museum will use the color E-ink. Yes color E-ink will provide some new new field for for artists. Because there's millions of colors right? Oh yes. But if using this kind of only monochrome type designers will find the good new field of all design I hope. Are there some other new emerging technologies in this area? When you talk about flexible and reflective displays did you have some talks here some different? I know there are many many new challenges for flexible OLEDs but I'm not so good at for OLED technology so I am interested in e-paper technologies. And you have for example you have a big Sony reader right? Yes. And so if you use this for example this is with the E-ink this amazing device you use it to check the documents from your students? Yes and actually I use this one for leading proceeding of this conference. It's awesome right? It's amazing this to have this big A4 smart display. I just would like to see nice application to collaborate on it. This is very PDF only right? Yes. Still useful. Very light. It should be revolutionizing the world right? This display should change the world. I hope so. If they just sell it it's just marketing right now right? The problem is a little bit high high applies. Price is a little bit higher. It's more expensive than the airplane to come here to SID.
