| Popis: | Numerous optical films have been developed to implement optoelectronics with advanced performance. In this study, we propose a color purifying optical nanothin film that improves the performance of optoelectronics by filtering the white light to have a spectrum composed of pure three primary colors of red, green, and blue. It was experimentally confirmed that a wider color gamut that covers 176.33% of the sRGB could be expressed when the suggested optical nanothin film was applied to a display system consisting of a white back light unit and color filters. Furthermore, a full width half-maximum value of 20 nm on average was observed in the three primary colors. When this film was applied to light recording optoelectronics, such as cameras, it acts as a multiband-pass filter that increases the sensitivity of the three primary colors. The principle of this optical nanothin film is based on multiple light resonance inside the film. A theoretical analysis and simulations were conducted to design the structure... |
