10‐1: Invited Paper: Novel Stacked Top Emitting OLEDs with Micro‐cavity to Realize High Performance Real RGB Display

In this paper 2‐stack RGB top emitting devices with micro‐cavity were realized and achieved high devices performance. The devices were based on similar structure, with a strategy of adopting varieties of HTL thickness before the first EML unit. The calculated mixed white light at D65 (0.31,0.33) came up with the current efficiency of 26.4 cd/A @10 mA/cm 2 , and the DCI‐P3 1976 color gamut of 99.7%. Further on utilizing the substrates with varieties of ITO thickness, the RGB devices can be realized with the same evaporation layers, which promotes this strategy to realize real RGB display.
