Entirely transparent pixels composed of monolithically integrated transparent organic light-emitting diodes driven by transparent thin-film transistors are presented. With an average transmittance of more than 70 % (see figure and inside cover) in the visible part of the spectrum (400–750 nm), the presented active pixels pave the way to the realization of fully transparent active-matrix displays. Low processing temperatures mean that flexible transparent displays may be feasible.
