Handling & Storage Precautions
- Avoid mechanical shock or dropping – glass panel is fragile.
- If LCD fluid leaks, wash skin/clothes immediately with soap and water; do not ingest.
- Use grounded workstations and anti‑static bags for handling and storage.
- Storage: 0~35°C, 40~60% RH, in sealed polyethylene bag, no direct sunlight.
- Hand soldering: use grounded iron, avoid flux spatters on display area.
- Do not disassemble or modify the module – warranty void.
Packing Method
Modules are placed in anti‑static trays, stacked with foam protection, fixed with cardboard, and sealed in cartons. Detailed packing drawings available upon request.
