Many users have been waiting to see
technology come into the mainstream for computer displays. Sure,
OLED screens are available on some cell phones and MP3 players (and
even the C6 Corvette's gauge
cluster), but those are relatively small displays compared to
what would be seen on a typical laptop, desktop or TV display.
Researchers at the Technical University
of Braunschweig are taking OLED technology one step further with the
development of a transparent
Their approach is to use transparent
TFTs (thin-film transistors) made of a 100-nanometer-thick layer of
zinc-tin-oxide, which transmits more than 90 percent of visible
light. Such transistors are more often made of silicon, which is used
for LCDs (liquid crystal displays) but is highly absorptive in the
visible part of the spectrum.
The displays can be varied in
brightness from 0 to 700 candelas per square meter by altering the
Could we be just one step closer to
Minority Report with interactive transparent displays, self-driving
cars and retinal scanners?
