Handling Notes

1. Electrostatic Protection: Use anti-static bracelets and grounded tools when handling. Avoid assembly in dry environments; recommended relative humidity 50%-60%. Do not touch pins, electrodes or FPC patterns directly with hands.
2. Cleaning Instructions: The polarizer surface is easily scratched. Clean with Scotch Mending Tape No. 810 or equivalent. Do not use water, ethyl alcohol, ketone or aromatic solvents, as they may damage the polarizer.
3. Storage Conditions: Store in anti-static vacuum bags with desiccant at 0℃~30℃, humidity ≤60%. Avoid direct sunlight, fluorescent light, high temperature/humidity or low temperature environments. Reseal if not used within 1 month after opening.
4. Operation Precautions: Follow power-on sequence (VDD → Initialization → VCC/VBAT → Display ON) and power-off sequence (Display OFF → VCC/VBAT OFF → VDD OFF). Do not apply input signals when logic power is off. Avoid fixed pattern display for long periods to prevent afterimages.
5. Assembly Tips: Do not apply excessive pressure to the glass panel or bend FPC forcibly. Shield the driver IC from light in product design to avoid malfunction. Install overcurrent protection (0.5A fuse recommended) in the VDD power circuit.
