4. Application Guidelines & Critical Notes
Intended Use
- Industrial control panels and human-machine interfaces (HMIs)
- IoT display nodes and smart home controls
- Handheld instruments and consumer electronics
- Any application requiring a compact, portrait-oriented display with a high-speed serial interface
Critical Design Considerations
- Interface (MIPI with 4 Data Lanes): This module uses a MIPI-DSI interface with 4 data lanes and 1 clock lane. The host MCU must have a MIPI-DSI controller that supports at least 4 data lanes.
- Power Supply: Provide stable IOVCC for the I/O interface, VDD for the main logic, and VCON for analog. The backlight requires a constant-current LED driver connected to LEDA (Anode, Pins 21, 22) and LEDK (Cathode, Pins 23, 24, 25), set to 40 mA at approximately 16.8V-17.4V.
- Mechanical Integration: Module outline: 64.20±0.15 × 0.15 × 5.0~20.50 mm (dimensions from drawing). FPC: 40-pin FPC.
- Temperature Limits: Operating Temperature: -20°C to +70°C. Storage Temperature: -30°C to +80°C.
Handling & Compliance
- The module is RoHS compliant and meets Halogen-Free standards.
- 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.

Main Design Focus
- The critical design task is properly implementing the MIPI-DSI interface with 4 data lanes to ensure reliable high-speed data transfer.
- Supporting requirements: Provide stable IOVCC, VDD, and VCON power. Provide a constant-current backlight driver set to 40 mA at 16.8V-17.4V. Mechanical integration — the module outline is 64.20mm × 0.15mm × 5.0~20.50mm. FPC connector — verify the 40-pin FPC.
This module is an excellent choice for industrial control panels, smart home devices, and any embedded application requiring a larger, high-resolution display with a high-speed MIPI interface.
