OLED was used in the Samsung Galaxy S2 for example. I think it's turned 
out not to be the killer of LCD for a few reasons: it uses more power 
than LCD, it struggled to keep up with the high ppi achievable with LCD, 
and the visual quality gap between OLED and LCD closed up a lot faster 
than people expected.

A lot of cool stuff is possible with displays, it's just nowadays 
everyone seems more concerned with price rather than cool features. For 
example BMW used to use a "transflective" LCD in their cars, where each 
pixel is divided into a reflective and transmissive part. This means 
even in direct sunlight the display looks just a good as in darkness. 
However they stopped using those because they were too expensive (many 
more steps in making the glass, plus a much stronger backlight), and in 
their eyes so long as the screen looks good in the showroom (where there 
is no sun) it doesn't matter how it looks out on the road. They saved 
their 20 euro on their 30000 euro car and they were happy.
