I believe that Felix was addressing the GaN for fast chargers. The "Western players" in the last paragraph should be implying Apple:

Okay. And then one question regarding your power business. So in Q1 you had roughly EUR 11 million sales in power. And I was wondering what was the split, silicon carbide versus GaN. And then on GaN, a little color around current market momentum or demand momentum. So TSMC seems to have secured some designs. They invested a few years ago. Do you see them investing in new capacities? And how is the investment behavior regarding GaN in China?
And then a final question regarding the OLED. Felix, you mentioned during your presentation a few months work still to be done, so an update there. Can we expect a decision still in first half?

Yes, thank you; quite a number of questions. Let me get started with the power electronics one. So order intake in the first quarter was about 20% gallium nitride, both power and RF combined, and about 20% silicon carbide, so power electronics amounting a total of 40%.
You are right regarding and commenting to the market momentum. The gallium nitride is now a leader, gaining traction. You may look and analyze, for example, across the Chinese smartphone market and see what models have been launched, a significant number of them being based on gallium nitride-based quick chargers. You can open them up and do a reverse engineering or buy the appropriate reports of that. Then you will see who the makers of these are.
A big part of that supply chain, some of them are fabless players, pointing then again back to fabless -- to foundries, one name you mentioned, that are producing and who see the demand picking up. So what you have stated is in fact also what we see when we look into the market, especially in Asia, especially in China.
That being said, the volume ramp, for which in 2019 we have seen and we have commented in displays to see a pick up moving from the R&D stage to a volume ramp stage, that volume ramp is now really ongoing with consumers being able to buy the products in the Best Buy, in the Media Mart or whatever these stores are called. That is happening.
With that, we do see orders from customers for expansion for volume and factory expansion coming, both the named and established players, one name you mentioned. And beyond that, we do see quite some momentum from smaller players and startups which are enjoying very healthy investment, both by venture capital and also by government entities in China. So China and Taiwan is a real strong voice in this ramp that we see.
And of course, we also see that the Western players, they may not be yet in the smartphone models. But they are, I think, very fast to follow this trend. Let me put it this way. So the gallium nitride power electronics ramp is now in the early phase.
