 We have been working on lighting solutions with Audi and OLED works for over four years now. At ST we are incredibly happy about how far we have come since the first demonstration of this collaboration was shown to the public for the first time at the international symposium on automotive lighting back in 2019. Since then this collaboration has come a long way as we are currently working on the next generation and of course our OLED technology is used in many of Audi's car models. Hi my name is Julia and today I'm here with Stefan Berlitz who is head of lighting development at Audi and he's going to tell us more about why OLED technology is of particular interest at Audi. Yeah actually we are very very happy about this collaboration with ST Microelectronics. We were looking actually for a possibility how can we address I would say yeah a few thousands in this case it was even one four thousand different LEDs OLED segments in this case and there was no possible solution on the market and yes we talked about this a years ago and we found then ST who was really then a partner to develop this new technology and you may ask why do they need four thousand different LEDs segments it's just lights on lights off no four thousand segments with this OLED technology it's something completely new the OLED technology we have different segments the segments are very precise have a high contrast our idea was to create some sort of a display on our rear lights and with this display we have then two different possibilities one possibility is of course some sort of show for our customers yeah we get a dynamic destination if you come to your car on the other side also you can choose your different signatures and that's actually possible on the one side and on the other side of course for us the main advantage of this technology is safety we can give safety communications for example if our car detects by a car to x communication oh there's a dangerous situation one kilometer two kilometers in front of the car we then can we know this information and then we give can give a warning to the drivers behind of us by for example showing a triangle to say them okay watch out a little bit there's some dangerous situation in the front so we have both some emotional and on the other side also the safety information and that's actually for us a very nice technology that we have and so we are very happy that ST gave us a possibility to develop this complete new innovation thanks Stefan I would say let's have a look at the demo in detail one of the main components to enable this beautiful light patterns is our new l99 LDL H32 a 32 channel LED driver that can control up to 4,000 light sources this device acts as the brain that drives and controls the individual pixels of the OLED panel in addition the driver has been equipped with a new can of D light communication interface developed by ST enabling monolithic microcontroller free solutions this interface has now also been standardized with the con in automation standard body this is particularly important as OEMs are demanding standardized protocols which are a key enabler for zonal architectures but this is not the end can of D light enables also dynamic animations and individualization of realize and is enhancing safety card to X communication with highest contrast and preciseness so if you want to create such animations yourself and test our l99 LDL H32 I recommend getting one of our eval boards which will soon be available to learn more about our LED drivers and ST go to ST.com and check out our website
