LED bulk

While organic light emitting diodes (OLEDs) are all the rage among gadget manufactures solid work in the area of inorganic LEDs has led to the development of semiconductor devices that could act as individual pixels in a display. John Rogers of the University of Illinois, Urbana-Champaign and colleagues have lifted the "simple" OLED fabrication technique, which involves layering materials, and applied it to their inorganic LEDs. The hope is that these lights could be eventually be produced en masse in parallel to act as the pixels of a display screen, rather than merely being used as a backlight source.
