- Reset Sequence: Ensure the RESET pin (Pin 37) is held low for a sufficient period during power-up to guarantee proper initialization.
Handling & Compliance
- The module is RoHS compliant.
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass and a 40-pin FPC – handle with care.
- Avoid bending the FPC sharply, especially near the connector interface.
- Do not attempt to disassemble or process the LCD module.
- NC terminals should be open. Do not connect anything.
- If the logic circuit power is off, do not apply the input signals.
