摘要

Abstract

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 innov

ative 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 1.04 cm

−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.
