- Reset: Proper reset sequencing is required for both the LCD (LCD_RST) and the Touch Panel (TP_RST) as per the power-on sequence.
- Touch Panel Integration: When integrating the In-Cell touch panel, ensure the host processor can communicate with it via the SPI interface. The TP_RST pin must be properly managed to ensure the controller initializes correctly.
- ESD Protection: The module has specified ESD performance (Class B). Ensure proper grounding and handling procedures during assembly and operation.
- Handling Precautions: Handle the module with care to avoid damage to the glass or FPC. Ground yourself to prevent electrostatic discharge (ESD).
