Very cool. So why did they sit on it so long? The tech to support it wasn't there?
OLED has been around for quite some time.
The problem has been stability of several of the compounds. The organic compounds break down under the energies of light stimulation in the diode.
This happens most rapidly in the short wavelengths (blue). To make matters worse, blue light has to be four times more voluminous (four times as
much) for our eyes to perceive it as being just as bright as, say, green.
This makes design of OLED screens somewhat challenging - and they all end up having life spans comparable to the first-generation Plasma screen
televisions (and we all remember how well that went over). Further, they are ultra-sensitive to UV light - so setting one in view of the sun will
(without proper shielding) kill its life span. Certain lighting solutions that do produce UV are also not recommended in conjunction with OLED
The other issues were the transistor substrates that serve to switch the LED on and off. While comparable to LCD backpane technologies, the
ultra-thin, flexible, transparent displays required a bit more development of transparent and flexible MOS-like materials.
Both of these problems have been remedied to a satisfactory level to permit introduction to the market. However - Quantum Dot is poised to succeed
the technology within the next five years - and will be, essentially, the penultimate 2d display technology- the brightness, speed, and depth superior
to Plasma with no burn-in and screens no thicker than a pane of plexiglass with virtually infinite dimensions (from the size of a computer screen to
the side of a building).
I'm holding off on buying a new TV and/or monitor until OLED hits the market. It will be a little bit before QD-LED hits the market.
