Key Features
✅ Ultra-Thin & Highly Integrated: Compact 2.17mm design, integrating MIPI interface and touch driver
✅ Industrial-Grade Protection: Passes ±8kV air discharge / ±4kV contact discharge ESD certification (IEC61000-4-2)
✅ Accurate Color Reproduction: 105% NTSC wide color gamut coverage, White point chromaticity coordinates (x=0.300, y=0.310)
✅ Low Power Consumption Design: Standby current ≤168μA (VDDIO), supports PWM dimming command (Register 51h)
Differentiating Highlights
Brightness Adaptability: Peak brightness of 495 cd/m² (measured value, see Page 17 optical table), 10% higher than the 6.01-inch module.
Energy Efficiency Optimization: Standby power consumption as low as 168μA (VDDIO), suitable for battery-powered devices.
Environmental Tolerance: Operates at -20°C (the 6.01-inch module operates down to -30°C), meeting requirements for mainstream industrial scenarios.
Color Accuracy: 105% NTSC color gamut coverage; blue chromaticity coordinates (x=0.140, y=0.047) enhance cool color performance.
Compatibility & Certifications
Driver Support: Built-in TE (Tearing Effect) prevention signal.
Reset Requirements: RESX pulse width >10μs (ESD protection details in Section 5.2).
Certifications: RoHS, CE
Lifespan: >30,000 hours (at half brightness)
Target Application Fields
▶ Satellite Communication Terminals
-20°C low-temperature startup ensures reliable operation in polar/high-altitude environments; 450 cd/m² brightness handles strong light conditions.
▶ Portable Gaming Devices
1ms ultra-fast response eliminates motion blur, and the wide color gamut enhances visual immersion in gaming.
▶ Thermal Imager Display Units
100,000:1 high contrast ratio clearly presents temperature gradients; wide temperature support enables field operations.
▶ Industrial Handheld Terminals
MIPI interface compatible with embedded systems; ESD protection resists electrostatic interference in workshops.
