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, FPC patterns or polarizer directly with bare hands.
- Cleaning Instructions: The polarizer surface is fragile and scratch-prone. Clean with adhesive tape (Scotch Mending Tape No. 810 or equivalent). Do not use water, alcohol, ketone or aromatic solvents.
- Storage Conditions: Store in anti-static bags at 23±5℃, humidity ≤60%RH. Avoid direct sunlight, high temperature/humidity or low temperature environments. Remove protective film before assembly.
- Operation Precautions: Follow correct power-on (VDD -> Initialization -> VCC -> Display On) and power-off sequences. Do not apply signals when power is off; avoid fixed pattern display for long periods.
- Soldering Tips: Welding temperature: 320~350℃; Welding time: ≤10 seconds per pin. Do not over-bend FPC (bending radius ≥5 mm) to prevent damage.
- Mechanical Protection: Do not crush, shake or jolt the module. The panel is glass-based, avoid mechanical impacts or pressure on the display surface.
