 Welcome to the Synaptics booth. I'm Paulina de la Garza. I work in the audio team. I'm going to present to you what is Resonate. Resonate is a new innovative technology, which is basically we're using the display as a transducer to generate some sound. Basically the display is becoming the speaker. This works because we have two PSO amplifiers, PSO transducers that are attached to the display and they are being driven by Synaptics' latest PSO amplifier. We target to generate equal loudness or even more loudness than traditional dynamic speakers. Some of the benefits as well is that since we're removing the speakers and also the LRA actuators for haptics, we can even have a slimmer mechanical design. This is naturally dust proof and waterproof since we are removing the holes of the speakers. Another good thing is that we can have some improved haptics and also we have force feedback capabilities. So you're making the sound coming from the display by ready? Exactly. And you can have an even more immersive sound since it's coming from the front and not from the sizeless traditional systems. Yes, of course. Go ahead. You can come closer. It's cool. It's not copyrighted music, right? No. Hopefully not. It's like a demo sound? Yeah. How's the quality of the sound compared to built-in speakers? So actually the sound is comparable to the traditional dynamic speakers. We're targeting to have the equal loudness. We can even have a little bit louder even. And also, I mean, this is really cool for when you're playing a game, you know, in your tablet or on your phone, you can be more immersed into it. Cool. Thanks. You can introduce your colleague there. Yes, of course. Yeah, let's go. Hey, how are you doing? I've just introduced myself. I'm Sam Toba, Product Marketing Manager for Touch Products at Synaptics. So what do we see here? So we have touch controllers on OLED products. And what we do is we sense the finger touch. Can you hold it in your hand? No, that's good. So what do you say? So we sense touch on OLED panels. We have different types of OLED panels that we support. We have rigid OLED. We have flex OLED. We have foldables which are becoming very, very popular as well. And then most recently we're supporting LTPO types of panels with touch. What's the LTPO? LTPO is the latest technology of the display where it saves power. It can go down to refresh rates as slow as 1Hz, all the way up to 144Hz. So they have variable refresh. It has difficulty for controlers. It's technically challenging and we support touch on that. How do you manage to make it work? We do tune for the different refresh rates on the panel. So we tune that in advance. And how do you make it work on the flexible? Flexible panels have special challenges because they're thin. They're very, very noisy. We have high sensitivity of the touch and we're able to sense through the very, very high noise on these panels. Noise? How does the noise on panels? Display noise on OLED panels is a very, very challenging problem because OLED is very, very thin. And the touch sensor is very, very close to the display. It makes it very, very challenging noise-wise to distinguish the finger touch signal from the noise in the background. Are you a market leader? Yes, absolutely. We work with all the display, almost all the phones or all the OEMs will use us. All the display manufacturers will use us. You don't have any competition? We have, of course, lots of competition. It's a tough market, but our customers like us and they've designed us into many, many phones. Thankfully. And the solution here is just a tiny little chip somewhere on the PCB? Yes, the solution here. Or do you go directly in the main SLC? No, the chip is connected to the display panel on a little flex that's hanging off this and folded in the back. So we connect to the touch sensor on the display panel. Is it amazing what happens every year here, the display week with the latest new displays? Oh, yeah. We're just going to be ready and working with them for each... Every year there's something new coming and the panels for us are getting thinner and thinner. It makes it very, very challenging. How good is the functionality? Good question. We support touch under difficult conditions such as thin panels, moisture, charger noise, car cradles. All sorts of conditions that our customers throw at us. We make sure it works under any condition. I remember how it was a little bit like 15 years ago and there was a resistive or something like that. Yes. And then capacitive came on. That's right. That was pretty cool when somebody figured that out. Was it synaptics that figured it out originally? We were one of the first... That convinced the Apple guys to do it? We were one of the first to support touch sensing capacitively, where we like to consider ourselves a pioneer in this area. So Steve Jobs was waiting for you to get it ready to launch an iPhone? Is that right? Like you were the core tech that was missing for Apple to decide to join the... We actually had a touch controller on a clear pad prior to iPhone. All right. So there was something happening, but it also had to be in a mass production. Sure. And it had to be super smooth. The display maker together with the touch. Back then it was a sensor maker that we worked with. All right. Cool. You were there all this time? No. I've been here since 2013. All right. Cool. Thanks a lot. Thank you. It's on? Okay. So my name is Vishal Shah and I run the product marketing for our display driver product line for Synaptics. And what do we see here? So here we are showcasing our display for VR products. Yeah. And this particular demo is showcasing our IP for which we call local dimming IP, which provides OLED-like performance with very high contrast on LCD screen. So that's this demo is showcasing that because the displays are very close to your eyes and high contrast ratio is really, really important for that. And in VR application, OLED is not a good technology. LCD is. And that's where local dimming is a very important piece of the IP that we provide to our customers. So you enable local dimming, which is kind of like also they call it mini-LED? Mini-LED. So mini-LED behind the screen. So you turn off some of the LEDs where the black is true black. Right. So you have to turn off the LED behind the display. And that's where you can get a very high contrast ratio. All that like display. True black is black. And then. Which one is yours? Both. Both are. So on and off performance. So this is on right now. But see with off, you can start seeing the gray effect versus this is black. True black versus this is if you disable local dimming, it looks gray. So this is turning on and off local dimming. And you can see it's very deep dark black when the local dimming is on. So that's what we provide. And the rest of the sets here are showcasing our end products that customers end product. MetaQuest Pro, MetaQuest 2, and this is the Pico Neo4. So these are some of the finished products in the market you can buy today using Synaptic's display driver. By going the LCD with mini LED route, people can get more brightness. Absolutely. You can enable the brightness, better contrast, very very high contrast with local dimming. And of course cost is very important. We provide benefit of using low number of zones compared to very high number of zones that you have to use if you don't have the IP. So that's a key value proposition. And pretty much entire portfolio of VR devices in the market uses Synaptic's. We have more than 80 percent market share in the VR market today. 80 percent. 90, more than 90 percent. 90. Yes. You can see everything, more than 40 models in the market using Synaptic's products. 4K plus resolution VR, 120 hertz. All this is possible because it's an LCD. Because LCD and we have a product with micro OLED as well, which will be out in the market later this year, which uses micro OLED. So we provide display driver for both LCD and micro OLED. The micro OLED, how is it, it's a direct miniality. Yeah, it's an OLED going directly to the display. Correct. Correct. Correct. So micro OLED requires very high, if you need very high PPI, very, very high resolution, LCD has a certain limitation. So LCD can go maybe 2,000 PPI. What micro OLED can go 3,000 to 4,000 PPI, which is required for the VR kind of application. And it's micro OLED or LED? Micro OLED. Micro OLED. Because micro LED also can work, but micro OLED is today it's more mature technology compared to micro LED. Micro LED development. So it's a micro display. OLED micro. Correct. Cool. All right. Thanks a lot. All right. Thank you. John Brady, I do automotive marketing here at Synaptic's. I want to show you a couple of our latest technologies. Why don't we take a look at this one first? So in local dimming, I'm not sure if your viewers are familiar with local dimming. So generally in an LCD, we have edge lighting that goes around the edges of it. And you can see it up here. See the edge light? And then that illuminates the whole panel. What that means is you get a lot of halo on it. Sorry, it's going to rotate around. In this particular one, it has a matrix backlight. So the LEDs are on in a matrix behind the display. It's going to come up right here. That's the one on the left-hand side, the right-hand side, sorry. And you can get a much better contrast ratio. So what I'm going to show in this demo here, this is a simulation of edge-lit LEDs. They're all on. And you can see what the contrast ratio is. Now I'll turn on the local dimming so it's dark where it's dark. All these LEDs go off and they're only on in this particular area. And we can do a nice comparison here, half and half. So there you can see there's a pretty major difference that you're getting. Hopefully it'll come out on there. And you can see in another automotive image, it's going to be on and off in the half and half display. This is something that many vehicles are going to have this starting, maybe this year, one or two, and they're going to start seeing it a lot more 25 and 26. And that's a contrast ratio to compare with OLEDs. OLEDs obviously have excellent contrast ratio. LCDs are just trying to approximate it in a more cost-effective way. Is there a crazy high brightness you can achieve? Because when you drive a car you want to have safety and you want to make sure people see the screen. That's an excellent question. So the two major things when you compare it to an OLED, is the contrast ratio is going to be like an OLED but not as good. The brightness, however, OLEDs generally 1,000 nits maximum, but more like 600 for running over the lifetime. In this type of panel, you can achieve 5,000 nits. So you have the whole glass roof, the sunlight coming in, it's being reflected off the panel, you can turn it up. 2,000 nits would be like a very high brightness, but 5,000 is achievable as well. What do you see here? On the other side. So right here, this is from Lucid Air. Lucid is the company, Air is the vehicle. So it's one of the newer EVs out there on the market. This has TDDI in it. TDDI means it has a touch and a display driver together, and the touch sensors inside the panel. Some things that are special about this one is this is called a freeform display. So you can see it's not a rectangular or rectilinear shape, it's actually curved down here, and so we have to do special adjustments for the display as well as a touch to work well at the edges. Something else you can see if you look at the edge here, this is also curved on top of it. So this is almost a 2 meter curve, and this is tighter over on this side, 800 millimeters. So we have to design our chips so that they're able to bend without breaking. Nice. So this is actually in a car, on the market. Yeah, it's a mass production. They started ramping last year, and so people had to pre-order them. Tens of thousands of these cars have already shipped. I was just over at Lucid there in the Bay Area, California. This is just talking about our latest chip. This is the SmartPridge, which does the local dimming. In this case, it's driving two displays off of one chip. It's something called MST, which is part of the EDP spec. And this is just showing the overall of the chip. You can drive with the 4,000 zones. The one I showed you earlier was 384 zones. This is capable of driving 4,000 zones, 30 inch 6K displays. So it's just a corner here showing the future of automotive. What's going to be coming in cars very soon? All right. And all your partners who are making the displays are ramping up, Daphne, you can do this in your 8, 10 different display manufacturers as well as tier ones. And OEMs are speccing local dimming into their vehicles right now. Here at 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.
