Abstract:
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: 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:
