To achieve higher resolution of optical filters in display applications, it is required to miniaturize the optical filters. However, many grating-based designs have been implemented that rely on structural color via surface plasmon polaritons (SPPs) that achieve chemical stability and high resolution. However, many reported color pixels have failed to realize color of high purity at subwavelength pixel sizes because of their strong dependence on periodicity. Herein, we propose an optical pixel design that does not rely on SPPs, but on the resonant reduction of scattering. Such hybrid nanostructure can transmit certain wavelengths of light even with a single array element without spectral degradation, achieving a pixel resolution of ~100,000 dpi. By arranging individual elements into an array, we can create color pixels that exhibit wide gamut and efficient transmission. Furthermore, by combining different elements in to an array, we can allow multi-bandpass transmission. |
