Abstract

The invention provides a stretchable ACEL device with adjustable working voltage and a preparation method thereof. The device comprises: a dielectric layer, which is located at one side of a first ionconductive layer; a composite light-emitting layer, which is positioned on one side, far away from the first conductive layer, of the dielectric layer; and a second ion conductive layer, which is positioned on one side, far away from the first conductive layer, of the composite light-emitting layer, wherein the dielectric layer is made of polydimethylsiloxane, and the composite light-emitting layer comprises a polydimethylsiloxane matrix and ZnS powder embedded in the polydimethylsiloxane matrix. By respectively adjusting the thicknesses of the dielectric layer and the composite light-emitting layer, the height-stretchable ACEL device with adjustable working voltage is obtained.

Description

technical field [0001] The invention relates to the field of light-emitting electronic devices, in particular to a stretchable ACEL device with adjustable working voltage and a preparation method thereof. Background technique [0002] Alternating current electroluminescent (ACEL) devices are widely used in advanced electronic systems due to their simple structure, high and uniform luminance, and long life. There are still some shortcomings that hinder the further development of ACEL devices. At present, stretchable ACEL devices based on ionic conductors have extremely high operating voltages, and it is difficult to obtain ACEL devices with the same luminous brightness and adjustable operating voltage. [0003] Based on the defects existing in the existing ACEL devices, it is necessary to improve them. Contents of the invention [0004] In view of this, the present invention proposes a stretchable ACEL device with adjustable working voltage and its preparation method to s...
