A blue single‐layer organic light‐emitting diode (OLED) was fabricated using a common hole transporter, N,N′‐diphenyl‐N,N′‐bis (1‐naphthyl) (1,1′‐biphenyl)‐ 4,4′diamine (NPB). By doping the NPB layer with RGB dopants, the luminance and the current efficiency have been improved enormously. The charge transport mechanism will also be examined.
