Critical Design Considerations
- Interface (MIPI): This module uses a MIPI-DSI interface for high-speed serial data transmission. The host MCU must have a MIPI-DSI controller to drive the display.
- Power Supply: Provide stable VCC (-0.3V to 3.6V) for the main logic. Provide stable IOVCC (-0.3V to 3.6V) for the I/O interface. The backlight requires a constant-current LED driver connected to the backlight pins, set to 160 mA at approximately 3V (Typ).
- Mechanical Integration: Module outline: 61.1mm (H) × 102.7mm (V) × 2.04mm (D). Active area: 56.16mm × 93.6mm. FPC: 40-pin FPC with PI reinforcement.
- Viewing Angle Characteristics: This module provides IPS viewing direction with 80° in all directions (Typ).
- Optical Performance: Luminance: 300 cd/m² (Typ). Contrast Ratio: 800:1 (Typ) – good contrast performance.
- Temperature Limits: Operating Temperature: -20°C to +70°C. Storage Temperature: -30°C to +80°C.
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.
