OLED Screen lifetime
1)What is sense to use organic LEDs for a screens but not just usual non-organic LEDS?
For some applications, they could be a lot cheaper. But I do think they have a bit of hype going too.
2)Why not to use light filters for OLEDS?For example white OLED have much longer lifetime than blue OLED.Why not just to cover white OLED pixel with some transparent blue material to obtain blue color?
I think it would defeat the purpose by adding unnecessary complexity. Plus all the energy emitted outside the blue range would be wasted.
