The method comprises the following steps: providing a fixed substrate with a heating function, and fixing a transparent conductive substrate on the fixed substrate; providing the first solution dissolving cavity injection materials, and scraping the first solution at the surface of the transparent conductive substrate far away from the fixed substrate to perform first heating process and prepare a cavity injection layer; providing the second solution dissolving luminescent materials, and scraping the second solution at the surface of the cavity injection layer far away from the transparent conductive substrate to perform second heating processing and prepare an active layer; and the active layer is far away from the surface deposition cathode material of the active layer to prepare a cathode layer.

Description

technical field [0001] The invention belongs to the technical field of light-emitting electrochemical cell preparation, and in particular relates to a large-area light-emitting electrochemical cell device and a preparation method thereof. Background technique [0002] The main technology being developed in the field of solid-state lighting today is light-emitting diodes (LEDs), especially organic light-emitting diodes (OLEDs). Traditional OLEDs have a multilayer structure, and their preparation methods are relatively complicated. In recent years, light-emitting electrochemical cells (LECs) have emerged as another alternative option. Compared with OLEDs, LECs have the following advantages: LECs device structure is relatively simple, electrode material requirements are relatively low (metal materials that are stable in air can be selected), luminous color can be adjusted, and driving voltage is low. LECs are expected to become the leader of the new generation of display tech...
