With a resolution of 480 × RGB × 800 and a robust NT35510 driver IC, this display offers a blend of clarity, efficiency, and durability.
Key Specifications at a Glance
Display Size: 3.97 inches
Resolution: 480 × 800 (WVGA)
Interface: RGB 24-bit
Driver IC: NT35510
Brightness: 400 cd/m² (typical)
Operating Temperature: -20°C to +70°C
Viewing Angle: 85°/85°/85°/85° (CR > 10)
Optical Performance: Clarity Under Any Condition
The SF-TC397B-8774C-T delivers a typical contrast ratio of 550:1 and a response time of 35ms, ensuring smooth motion and sharp imagery. Its wide viewing angles (85° in all directions) make it suitable for multi-user or multi-orientation devices. The white LED backlight provides uniform illumination with 80% minimal brightness uniformity, critical for consistent visual performance across the panel.
Built for Reliability
Designed to withstand harsh environments, this module has passed stringent reliability tests, including:
High-temperature storage (80°C for 120 hours)
Low-temperature operation (-20°C for 120 hours)
Humidity resistance (40°C, 90% RH for 120 hours)
Thermal shock cycling (-20°C ↔ 70°C)
These tests ensure that the display performs reliably in applications ranging from outdoor kiosks to medical monitors.
Electrical and Interface Flexibility
The module supports a 24-bit RGB interface and operates at a logic voltage of 2.8V, with an optional I/O voltage of 1.8V. Its low power consumption (typical current 5mA) makes it ideal for battery-powered devices. The integrated backlight uses 8 white LEDs driven at 20mA, offering long life and stable output.
Conclusion
The SF-TC397B-8774C-T is a versatile, high-performance display solution that combines optical excellence with mechanical and electrical robustness. Whether you're designing a portable medical device, an industrial HMI, or an in-vehicle display, this module offers the reliability and performance you need.
