Abstract
Abstract

Traditional bottom light emitting devices are commonly limited by the light transmittance of the substrate and electrode, while the recent emerging inorganic alternating current electroluminescence (ACEL) devices, which manifest excellent application prospects in the field of flexible display are mainly prepared by directly mixing thermosetting resin and powder materials. Here, the electrode layer, dielectric layer and light-emitting layer based on different electrode structures, were printed in different orders and structures by the inking technology. Printable inorganic ACEL devices with bottom-emission structure (BES), top-emission structure (TES) and planar electrode structure (PES) were successfully obtained. The measurements of luminescent properties of printable ACEL with different electrode structures under different voltages by spectrometer indicated that BES-ACEL had the best brightness. Besides, TES-ACEL and PES-ACEL have the outstanding advantages of no substrate limitation and interaction characteristics, respectively. Therefore, this work opens up the new path for ACEL devices towards application in the fields of printing and packaging, interactive and intelligent display.
