dc.description.abstract | Erstwhile, displays using down-converting color changing medium utilized color filters as an essential part of clarifying the trade-off between true colors and transmittance. In this study, we report the development of a novel, smart process for producing thin luminescent films that completely convert colors and enhance light intensity. Highly dense films are prepared by the co-deposition of perovskite quantum dots and metal oxide particles as color conversion layers and scattering agents, respectively. These layers can be directly deposited on blue organic light-emitting diodes using ultrasonic-assisted aerosol deposition (UAD). This method can allow displays using a down-conversion system to streamline the process due to absence of color filters. Using this method, films can be a minimum of 3 mu m thick for complete conversion of blue light, a quarter that of inkjetprinted films. We demonstrate 7,353 cd m(-2) in green and 411 cd m(-2) in red converted emissions with no blue light leakage. Furthermore, the developed technique was shown to be compatible with versatile patterning processes. For example, UAD may be combined with a fine-metal shadow mask to produce a pattern of 30-mu m-diameter dots. Even without using a mask, the method still produces a pattern of 13 mu m wide lines. This system provides a new approach that may serve as an alternative to inkjet printing. | - |
