Handling Notes
- Electrostatic Protection: Use anti-static bracelets and grounded tools during handling.
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 to ensure display clarity and avoid light blockage.
- Storage Conditions: Store in anti-static bags at 23±5℃, humidity ≤45±20%RH. Avoid
direct sunlight, high temperature/humidity or low temperature
environments (below 0℃). Use modules within 6 months; recheck
performance if stored over 12 months.
- Operation Precautions: Follow correct power-on/power-off sequences to avoid damage. Do
not apply signals when power is off; avoid fixed pattern display
for long periods to prevent afterimages.
- Soldering Tips: Control soldering temperature and time to avoid PCB or pin damage.
Ensure reliable soldering of contact sides to prevent poor contact
and signal instability.
- Mechanical Protection: Do not crush, shake or jolt the module. The panel is fragile, so
avoid mechanical impacts. Do not apply pressure to the display
surface or bend PCB excessively.
- Glue Application: Ensure correct application of 3M#1318B glue (10X8X0.05mm) to
guarantee stable installation without affecting display
performance.
- Power Supply: Do not exceed absolute maximum ratings of each pin to prevent
permanent damage. Install overcurrent protection for stable power
supply.
