Non‐doped ultrathin emissive layer based OLED is demonstrated to be a promising novel structure to stimulate two‐color dual emission through exciton management. By using a ultra‐thin TAPC interlayer as a hole‐trapping layer, exciton redistribution is realized and dual emission are observed without using any doped layers. The mechanism of this trapping interlayer is further discussed.
