In this paper, core-shell nanoparticles are used to provide a transparent high-quality display. To realize this idea, Si-SiO2 core-shell nanoparticles have been used to achieve the most suitable nanoparticle composition for a transparent color display with high transparency and contrast. For color transparent monitor the superimposed QDs are used. For transparent color monitors, stacked QDs are used. In this work, we determine the ratio of nanoparticles (three QD ratios) for the three colors in the proposed monitor. Because the red, green, and blue scattering peaks are different because of the scattering physics, which is wavelength-dependent. Therefore, obtaining the optimal ratio for each color is studied. The numerical method of Finite-Difference Time-Domain is used to simulate and calculate the optical properties of the proposed transparent monitor. The effect of different combinations of nanoparticles to have the maximum dispersion at blue, green, and red wavelengths and the minimum absorption at other wavelengths has been investigated. Finally, the optimum ratio and arrangement of nanoparticles for all colors are reported and numerically evaluated.
