White Light‐Emitting Diodes By introducing organic multifunctional material 4,4'‐cyclohexane‐1,1‐diylbis[ N,N ‐bis(4‐methylphenyl)aniline] (TAPC) to flexibly control the hole and electron distribution, maintain charge balance and extend exciton formation region within the device, efficient organic/inorganic p‐n heterojunction white light‐emitting diode (WLED) is realized. The resulting hybrid WLED shows a peak current efficiency of 20.6 cd A −1 , and a near purity white light with color coordinates of (0.32, 0.33), which indicates promising applications in solid‐state lighting and information display.
