LIGHT MODULATOR WITH CONCENTRIC CONTROL ELECTRODE STRUCTURE

摘要

An electronic device (10) for at least partially displaying a pixel of an image, the device comprising first and second reflectors defining an optical cavity (60) therebetween, the optical cavity being selective of an electromagnetic wavelength at an intensity by optical interference, the device having a concentric control structure (25) comprising at least an inner (100) and an outermost (105) electrode, the optical cavity (60) being controlled only by the inner electrode (100).
