- Industrial control panels and human-machine interfaces (HMIs)
- Any application requiring a compact, high-resolution display with a standard MIPI interface
Critical Design Considerations
- Interface Selection: This module supports a 4-lane MIPI DSI interface. The host processor must have a MIPI DSI controller capable of driving 4 data lanes.
- Power Supply: Provide stable VCC (3.3V typical) for core logic and IOVCC (1.8V typical) for I/O. The backlight requires a constant-current LED driver set to 120 mA at approximately 12V.
- Mechanical Integration: Module outline: Not specified. Active area: Not specified. FPC: 40-pin FPC.
- Temperature Limits: Operating Temperature: -20°C to +70°C. Storage Temperature: -30°C to +80°C.
- ESD Protection: Observe standard ESD precautions during handling and assembly.
- Reset Sequence: Ensure the RESET pin 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.
