Patent ID: 10629771

Abstract:
The disclosure provides a perovskite light-emitting diode (LED) and a fabricating method thereof. The fabricating method of the perovskite LED of the disclosure fabricates a perovskite light-emitting layer by doping a suitable polymer material into the perovskite material. On one hand, the film-forming property of the perovskite material can be enhanced, and the pinholes in perovskite light-emitting layer are reduced and then the luminescence of perovskite LED can be enhanced; on the other hand, the physical properties of the inkjet ink of the perovskite light-emitting layer can be effectively adjusted to meet the needs of the inkjet printing process and to enhance the ink-jet printing effect of the perovskite light-emitting layer. The perovskite LED of the disclosure is fabricated by the method, and the perovskite light-emitting layer has good film-forming effect and basically no pinhole. Therefore, the perovskite LED has a better light-emitting performance.
