For many the ideal form of in car electronics like GPS
navigation systems and entertainment devices like TVs would be
clear devices that only show up when in use. This type of
technology could create GPS navigation display embedded into the
windshield of a car so you can see a map without having to take
your eyes off the road. Researchers at Purdue University have
created the first active matrix display that uses a new class of
transparent transistors and circuits. The researchers say this
is a first step towards flexible color monitors and “heads-up
displays” in car windshields. The transistors used in the
display are made of nanowires, which are tiny cylindrical
structures assembled on thin glass or plastic films. The
nanowires used by the researchers for the display are as small
as 20 nanometers or about a thousand times thinner than the
average human hair. The nanowires were used to create an OLED
display that rivals current flat-panel TVs in brightness. David
