Description
Summary:In this study, we aim to explore the application of a resonant cavity structure in quantum dot full-color display technology, with a specific focus on the impact of black matrix (BM) width on display performance. We propose two theoretical calculation methods to evaluate how BM width influences the image performance of displays. Through systematic investigation, we observed that increasing the BM width from 0 nm to 25 nm can decrease the cross talk between subpixels from 48.65% to 0%. Additionally, improvements can be made to reduce the Aliasing Effect between subpixels. The color gamut of the images can be enhanced across all three display structures examined in this research. Notably, the display featuring the Ag/ZnO/Ag sandwich structure achieves a color gamut ratio of 100.65% Adobe RGB, with a color gamut coverage of 87.17% Adobe RGB.
