Color display using micromechanically coupled mirrors

Abstract

We present interferometric modulators, reproducing green, blue, and red colors using selective actuation of mechanically coupled mirror arrays having an identical air gap for simple fabrication process. The present interferometric modulators reproduce green, blue, and red colors at switching modes of (000), (010), and (101), where the spectrum peaks for the colors are measured at wavelengths of 511 +/- 5, 478 +/- 3, and 644 +/- 9 nm with maximum intensities of 77 +/- 5%, 73 +/- 2%, and 81 +/- 5%, respectively. Therefore, we experimentally demonstrated the color reproduction capability of the present interferometric modulators for display applications. (C) 2010 American Institute of Physics.
