The flexible ACEL device was fabricated on ITO/PET electrode using copper-doped zinc sulfide （ZnS： Cu） phosphor as luminescent molecule， polydimethylsiloxane （PDMS） and barium titanate （BaTiO₃） as insulating material by scraping technology. The effects of different material mixing ratio， driving voltage and frequency of composite luminescent layer on the photoelectric properties of the device were studied. The results showed that the luminance of flexible ACEL devices increased with the increase of phosphor and barium titanate content. When ZnS： Cu/BaTiO₃/PDMS=2∶ 2∶ 1， the device performance was the best， and the lower opening voltage could be achieved. The luminance could reach 1.16 cd/m² at 40 V and 2 kHz. Finally， the flexible ACEL device was integrated with the vertical contact separation friction nanogenerator. The maximum output voltage and current of the TENG could reach 360 V and 46 µA， which could light up the flexible ACEL devices. The self-powered flexible ACEL devices could provide a new method for wearable display and interaction.
