Claim One:
1. An apparatus, comprising: a display panel with a plurality of Fabry-Perot cavities; an illuminator that provides light to the plurality of Fabry-Perot cavities; and a modulator that is connected to the plurality of Fabry-Perot cavities, the modulator being controlled by a controller to provide modulation signals to the plurality of Fabry-Perot cavities, wherein: the plurality of Fabry-Perot cavities generates an image from light provided by the illuminator, each pixel of the image corresponding to a respective one of the plurality of Fabry-Perot cavities, the controller controls the modulator to provide image modulation data to the plurality of Fabry-Perot cavities for generating the image, the modulator providing color information to a first cavity of the plurality of Fabry-Perot cavities for setting a size of the first cavity to correspond to a color of a first pixel of the image, the modulator providing gray level information to the first cavity for generating a gray level of the first pixel based on a transmission spectra of the first cavity, the display panel display pixels of the generated image based on colors and gray levels of each pixel of the generated image, and the gray level is represented by: ∫ 0 t ⁢ ∫ λ min λ max ⁢ S i ⁢ ⁢ ( λ ) ⁢ ⁢ ⅆ λ ⁢ ⁢ ⅆ t g i_ ⁢ 100 where S i (λ) represents the transmission spectra of the first cavity for a discrete peak wavelength setting represented by index ‘i,’ λ min and λ max are minimum and maximum wavelengths in visible range of light spectra, g i — 100 represents maximum gray level for channel index ‘i’ used to normalize the gray level, N number of gray levels are required for the display panel and total time over which channel ‘i’ is on satisfies the following condition: T ≤ ∑ i = 1 N ⁢ ⁢ T i .
