Abstract:
Additive color mixing across the visible spectrum was demonstrated from a light emitting diode (LED) pixel comprising of red, green, and blue subpixels monolithically integrated and enabled by local strain engineering. The device was fabricated using a top-down approach on a metal-organic chemical vapor deposition-grown sample consisting of a typical LED epitaxial stack. The three color subpixels were defined in a single lithographic step. The device was characterized for its electrical properties and emission spectra under an uncooled condition, which is desirable in practical applications. The color mixing was controlled by pulse width modulation and the degree of color control was also characterized.

Claim (Index 9):
A multi-color light device, comprising:\n a substrate; three subpixels formed on the substrate, each subpixel includes one or more nanopillars serving as light emitting diodes (LEDs), such that diameter of the nanopillars within a given subpixel is the same but diameter of nanopillars differs between the three subpixels; a controller electrically coupled to the nanopillars in each of the three subpixels and configured to supply driving signals to the nanopillars in each of the three subpixels, such that magnitude of driving signals is the same amongst the three subpixels but duty cycle of the driving signals are adjustable independently amongst the three subpixels. wherein controller determines an intensity ratio between the three subpixels to achieve a desired color of light and sets the duty cycle of the driving signals in accordance with the determined intensity ratios.
