4. Application Guidelines & Critical Notes

• Power Supply: The module requires VCC (3.3V typical) and IOVCC (1.8V typical) power supplies. Ensure the power supplies are stable and have low ripple.
• Interface: This module uses MIPI DSI interface with up to 4 data lanes. The host processor must be configured for the appropriate DSI data format (RGB565, RGB666, or RGB888) and lane count.
• Backlight Driver: A constant current driver is required to supply the backlight via the LEDA (Pins 1-3) and LEDK (Pins 5-8) terminals.
• Reset: Ensure the RESET pin (Pin 27) is driven low for a sufficient pulse width to initiate a proper reset before initializing the display.
• MIPI DSI Configuration: The DSI clock frequency and data lane speed must be configured according to the desired color depth (RGB565, RGB666, RGB888) and the number of active lanes used. The module supports speeds up to 850 Mbps per lane (for RGB888 with 4 lanes).
• Mechanical Mounting: Follow proper mechanical design guidelines to ensure correct fit and avoid damage to the glass, FPC and integrated touch panel.
• Operating Temperature: The module operates from -20°C to +70°C. Satisfactory display performance is only guaranteed within this range.
• Storage: Store the module in a clean environment, free from dust, moisture, and direct sunlight. Storage temperature range is -30°C to +80°C.
• Handling Precautions: Handle the module with care to avoid damage to the glass or FPC. Ground yourself to prevent electrostatic discharge (ESD).
