This manual explains the principle, structure, fabrication process, electrical characteristics, and usage guidelines for plastic electroluminescent (EL) sheets.
The document introduces the basic principle of electroluminescence, its historical development, and the specific technology used for plastic EL sheets. It describes the material composition, layer structure, and the manufacturing steps such as screen‑printing of conductive, emissive, and dielectric layers.
It also covers the electrical parameters, lifetime considerations, design recommendations for driver circuits, and detailed technical specifications. A list of driver modules and formulation recipes for the phosphor paste is provided, along with packaging and handling instructions. This manual is written in Chinese.

The sheet is designed to operate at an AC voltage of 110 V to 140 V.
Typical continuous operation life is between 5 000 and 10 000 hours, measured to half‑brightness.
The recommended driving frequency is between 50 Hz and 1 kHz.
The sheet thickness is typically 0.2 mm to 0.5 mm.
