 So the latest so let please introduce yourself. Oh, I'm Ching-Tang and Is it true that you invented the OLEDs? That's true How many years ago now? 1978 How's your feeling? Knowing that it's changed the world so much like so many people use the OLED, right? Well, I'm happy to see you all that being used, you know, the widely It's for researchers that some You know, it's a good reward. It makes you feel just because not everybody can research something that Become such a big success, right? Many people research for stuff and it's hard to see where their impact goes. Well, I mean in most research Particularly, you know, the one that I know about OLED I, you know, you came up with the idea or maybe you accidentally ran into it And you discovered, you know, 50 years ago not quite 50 years ago The point is that it takes tremendous amount of effort not just yourself, your team in my days at Kodak and you also have to have somebody willing to invest in a factory and That's how you have it today. So it's not a single man effort. It's a tremendous industry But maybe I can take a little credit being the first one to come up with it So, is it by chance? Did you come up by chance with it or you focus on this direction? I focus on that one direction and then OLED came about and then I refocus so you can say it's by accident and Is it How did you manage to or did you have to convince more and more people to join and and to work on this direction? Or is it thanks to display week like 45 years ago? There was a display week and everybody's like wow and everybody says okay I want to invest one billion or no, I mean the basically the invention was to switch the material You have LED at a time, but you don't have organic material based LED So once that was to even that was not discovered by myself It's something called organic electro luminescence. That was discovered maybe a hundred years ago All right, so but you you get it down to practical level Not practical, but you know in research wise it's practically enough for you to invest into to invest time into And so it's a switch from Semiconductor first ring semiconductor to organic amorphous material that is a major change And after that everybody recognizes that's a good material to use and you have something to that How good is it today? Is it much better than you could imagine or is it not as good as you hope it should be? No, no, it's much better than I expected so much better much much better these are if we check this one for example, so this one is a it's an organic based Display right, but the biggest the challenge is to put the RGB together and They trying to use a very brutal effort Like this what do you say put what together to put it together Closer Yeah, sorry, I'm just trying to put the photography Photography is the base to make the RGB pixels Nice I'll be doing a video with you just after about about this So you can introduce so I Was just on a uber and there was this guy with a foldable Samsung phone and he said it was the third one he already bought and like so many people have foldable Flexible is this enabling some flexibility? One step further All right, I'm not trying to do a commercial phone. No, of course, but Normally you do it by shadow masking Yeah, even the foldable, but this one they cut pretty elimination of asking which is a big deal well All right, so but it would take some time for them to You know commercialize it and really bring the cost down and so All right, what's up all this stuff you talk about the shadow masking and everything was that already happening 30 years ago? No, no, no, no the shadow masking happened maybe 15 years ago or something 15 times when that enabled all the technology Because LCD and all those they they used for the top of you mainly But all that requires shadow masking technology to put down the RGB Except for the TV TV completely just different I'm very happy with my OLED TV, and I was trying a little bit with a with a LCD but I My my wife she said no no we need to get the OLED When she look at the store, you know how the quality and now They also Not only doing the phone displays now to do the TVs Is it's completely different world the OLEDs on TVs and Mobile was it very similar the order TV has credit to set to not to Samsung to LG LG is the one who pioneered a TV Yeah, so you should go to their booth to see the order TV But now they're also doing the OLED TVs, right? But they come late They came much later yeah, so You know it's still over TV, but the Technology get started By you know first at Kodak, and then the LG TV Is it amazing to think in the the scale of these companies how much you invest in the factories? And you can sit there and you imagine You can ask them how much money they spent on there. Yeah Investments, I mean how much money you spend on the investment How much the investment that you have to make to build an older TV It's a secret right They're talking about in the unit of hundred million dollars. It could be ten of such unit But you know a hundred million dollars to build a manufacturing But you know there's now we eight billion people Everybody needs an OLED, right That's a good investment. I I don't think everybody would need an OLED No Not everybody. No, I mean you need to put food on your mouth first All right, but maybe you can become more and more affordable. Is that possible? It definitely will be more and more affordable. Do people want to print them as difficult Well, I mean they can do the evaporations the printing would come whenever they can make it But it's not there yet All right. It's it's true. You got the Nobel Prize. No, no No, you should No, okay. All right. How about meeting all your colleagues here? That's what you're gonna do now Yeah, we just want to walk around and you know to see what's new here. Okay. Thank you so much Okay, can you give you my card? I have it. Yeah, it's right there You guys can send me some money you can send money on wise it's really smart Oh, you don't have to send me money you can send money to your friends to your family Are they in a different country?
