4. Application Guidelines & Critical Notes
Intended Use
- Industrial control panels and human-machine interfaces (HMIs).
- Embedded systems requiring a standard 7.0-inch display with MIPI interface, IPS technology, and wide viewing angles.
- Applications requiring low driving voltage and low power consumption.
Critical Design Considerations
- Interface (4-lane MIPI DSI): This module uses a 4-lane MIPI DSI interface. The host controller must support 4-lane MIPI to drive the 1024×600 resolution. Ensure proper MIPI termination and matching.
- Power Supply VDD: The VDD pin (Pin 30) is the digital power supply. The test condition for reset timing is VDD=1.8V~3.3V. The MIPI logic operates from this supply.
- Backlight Driving: The backlight operates at 9.6V (Typ) and 140mA (Typ). A constant-current LED driver is required. The LED configuration is 3 LEDs in series and 7 in parallel.
- Reset (LRSTB): The LRSTB pin (Pin 29) is an active-low global reset. The reset low pulse width must be at least 6 µs (Trst min) for proper initialization, as per the specification.
- Standby Mode (STBYB): The STBYB pin (Pin 28) controls standby mode. It must be pulled high for normal operation. When set low, the timing control and source driver will turn off, and all outputs become high-Z.
- Temperature Limits: Operating Temperature: -20°C to +60°C. Storage Temperature: -10°C to +50°C.
- Low Reflection & High Color: The TFT-LCD panel is adapted for low reflection and higher color type, making it suitable for applications where ambient light reflection is a concern.
- Power Sequencing: A proper power sequence should be followed. The MIPI interface should be active before backlight is turned on to prevent abnormal display.
Handling & Compliance
- The module is ROHS Compliant.
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass and 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.
