P‐202: Improvement of the Difference in Light Output from both sides of Dual Emission OLEDs

The advantages of utilizing dual emission display in relation to information interaction and customized display have been widely acknowledged. Organic light‐emitting devices (OLEDs) are an effective solution for future dual emission displays, however, the influence of electrode materials and device structure results in significant differences in the optical performance on both sides. Here, we adjust the optical microcavity effect to balance the light output from both sides so that the top and bottom of the display can be seen with the same brightness and chromaticity. The structure of an OLED for dual emission display has been fabricated.
