One idea about OLED screens was that if they can be made cheap enough and standardized, a
short life (a year, or even a few months) wouldn't matter. They're basically a sheet of
high-tech plastic. You'd remove the old one and plug in a new one, like changing a light bulb.

If blue is a problem but red and green work, the technology might be usable without blue. The
oldest colour photography processes used only two colours, not three. It's amazing how well
the brain interpolates the colour that isn't there! (For a similar reason, it's possible to be
colour-blind and not know it, if you've never been scientifically tested).
