3.7 Design Notes from Documentation
- B/L Driver: The backlight driving condition is IF=20mA, Vf=19.6V (TYP) for 6 LEDs in series. An external boost converter is required.
- Mechanical: Tolerance of segments to edge of glass: ±0.2mm. The FPC includes PI reinforcement with a total thickness of 0.3mm (FPC+PI). The LCM module has a total thickness of 2.11±0.15 mm (per the drawing).
- FPC Bend Area: The FPC has a designed bend area. Yellow insulating tape is used for the FPC bend area protection.
- Housing: It is recommended that the housing visual area be at least 0.3mm smaller than the VA (Viewing Area) on each side. The housing foam window should be at least 0.6mm larger than the VA on each side. The TP edge should not contact metal conductors to avoid ESD or short circuit risks.
- RoHS: All materials must be ROHS compliant.
- Connector: The FPC has 25 pins. The pitch appears to be 0.5mm based on the drawing.
- Components Height: The maximum component height on the FPC is 1.0mm.
4. Application Guidelines & Critical Notes
- Power Supply: The module requires a 2.8V (VDD) and 1.8V (IOVCC) power supply for the LCD, and a 3.3V supply for the CTP. Ensure the power supply ripple is minimized.
- Interface: The display uses a 2-lane MIPI DSI interface. The touch panel uses a dedicated I2C interface. The host processor must be configured for these protocols.
- Backlight Driver (External): An external boost converter is required to supply the high-voltage backlight via the LEDA and LEDK pins. The required driving condition is 20mA total current at 19.6V forward voltage (Typ).
- Reset: A hardware reset pin (RESET, Pin 10) is provided. The reset pulse duration must be at least 10 µs. It is necessary to wait 5ms after releasing RESX before sending commands. Also Sleep Out command cannot be sent for 120msec.
- Operating Temp: The module operates from -20°C to +70°C. Below 0°C, the response time of the liquid crystal becomes slower.
- Storage: Storage temperature range is -30°C to +80°C. Humidity must be controlled per the specification.
- Handling Precautions: Handle the module with care to avoid damage to the glass, FPC, or CTP. Ground yourself to prevent electrostatic discharge (ESD).
