Interferometric modulators using mechanically coupled mirror actuators for color reproduction

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 the wavelength of 511μ5 nm, 478μ3 nm, and 644μ9 nm with the maximum intensity of 77μ5 %, 73μ2 %, and 81μ5 %, respectively. Therefore, we experimentally demonstrated the color reproduction capability of the present interferometric modulators for display applications.
