Vertically stacked all-organic active-matrix organic light-emitting diodes are promising candidates for high-quality skin-like displays due to their high aperture ratio,extreme mechanical flexibility,and low-temperature processing ability.However,these displays suffer from process interferences when interconnecting functional layers made of all-organic materials.To overcome this challenge,we present an innovative integration strategy called"discrete preparation-multilayer lamination"based on microelectronic processes.In this strategy,each functional layer was prepared separately on different substrates to avoid chemical and physical damage caused by process interferences.A single interconnect layer was introduced between each vertically stacked functional layer to ensure mechanical compatibility and interconnection.Compared to the previously reported layer-by-layer preparation method,the proposed method eliminates the need for tedious protection via barrier and pixel-defining layer processing steps.Additionally,based on active-matrix display,this strategy allows multiple pixels to collectively display a pattern of"1"with an aperture ratio of 83％.Moreover,the average mobility of full-photolithographic organic thin-film transistors was 1.04cm2V-1 s-1,ensuring stable and uniform displays.This strategy forms the basis for the construction of vertically stacked active-matrix displays,which should facilitate the commercial development of skin-like displays in wearable electronics.
