Dual‐Microcavity Technology
In article number 2305528, Kwan Hyun Cho, Yun Seon Do, and co‐workers present a dual‐microcavity structure that consists of the same thickness of the R/G/B subpixels. This results in reducing the complexity of both the design and fabrication. Also, the dual‐microcavity structure provides higher efficiency and high color purity in the R/G/B, simultaneously. This technology...
Microcavity structures are used in inorganic‐, organic‐, quantum‐dot‐, and perovskite‐based electroluminescent (EL) devices to advance next‐generation displays. However, there are difficulties in controlling electrical characteristics and patterning processes for producing different thicknesses for each red, green, and blue (RGB) subpixel, and the issues are more challenging in the high‐resolution...
