Handling Notes
Electrostatic Protection: Use anti-static bracelets and grounded tools. Avoid assembly in
dry environments (recommended relative humidity 45%~60%). Do not
touch pins, PCB patterns or polarizer directly with bare hands.
Tape Removal: Remove the protective tape (maximum thickness 0.15mm) before
installation.
Storage Conditions: Store in anti-static bags at 23±5℃, humidity ≤45±20%RH. Use within
6 months.
Operation Precautions: Follow correct power-on/power-off sequences. Avoid fixed pattern
display for long periods.
Soldering Tips: Control soldering temperature and time to avoid PCB damage.
Mechanical Protection: Do not crush, shake or jolt the module. Avoid mechanical impacts.
Glue Application: Ensure correct application of 3M#1318B glue for stable
installation.
Power Supply: Do not exceed absolute maximum ratings. Install overcurrent
protection.
