Handling Notes
Electrostatic Protection: Use anti-static bracelets and grounded tools. Avoid assembly in
dry environments (45%~60% RH). Do not touch pins, PCB patterns or
polarizer with bare hands.
Polarizer Protection: Clean polarizer with Scotch Mending Tape No.810. Avoid water,
alcohol, ketone and aromatic solvents.
Storage Conditions: Store in anti-static bags at 23±5℃, humidity ≤45±20%RH. Avoid
direct sunlight and extreme temperatures. Use within 6 months.
Operation Precautions: Follow correct power-on/power-off sequences (100ms delay). Avoid
fixed pattern display for long periods to prevent afterimages.
Soldering Tips: Control soldering temperature and time. Ensure reliable soldering
to prevent poor contact and signal instability.
Mechanical Protection: The panel is glass-based; avoid mechanical impacts, pressure and
excessive bending of COF.
Light Shielding: Shield OLED driver from light in product design to prevent
malfunction caused by light exposure.
Power Supply: Install 0.5A overcurrent protection on VDD circuit. Do not exceed
absolute maximum ratings.
