So Hugo, I gather from this that you've actually considered using them?
So it's still possible we'll see an OEL display in a future Empeg product?

I can't say I've had problems with pixel life on my headunit. I haven't noticed any dead pixels yet and it's (contrary to what I've said before - time flies) almost two years old. I did notice this inverted display syndrome you mention, but this is simply an option which is easily turned off. I have to admit, the first time I saw this I thought my display was broken. After actually reading the manual (ugh!) this option was turned off fast. I haven't had any problems with my unit since, AND I've already dropped it a few times. (yeah I know...I was blessed with two left hands...)
