Engineered for Industrial Resilience & Precision

The SFTO400XC-7013ACT is a high-performance 4-inch square TFT LCD module designed for demanding industrial applications in harsh environments. Featuring a 720×720 resolution with 262K colors and an 18-bit RGB interface, it delivers exceptional clarity for HMIs, IoT control panels, and instrumentation.

Key Technical Differentiators

  1. Robust PCAP Touch Integration

    • Multi-touch support via FT6336U IC (I²C interface).

    • Customizable configurations: G+F (Glass/Film) or G+G (Glass/Glass) structures.

    • Optional industrial-grade touch ICs (-40°C to +85°C, ±15kV ESD).

  2. Extreme Environment Readiness

    • Validated for thermal cycling (-30°C to 80°C storage) and vibration resistance (10–55Hz, 1.5mm amplitude).

    • IP67-sealed variants available (gasket + potting).

    • Hydrophobic coatings (>110° contact angle) for wet/outdoor use.

  3. Optical Excellence

    • 900:1 contrast ratio with 80° omnidirectional viewing.

    • Anti-glare (AG) + anti-reflective (AR) coatings (optional).

    • ≥82% light transmission (upgradeable to 90%).

  4. Compliance-Driven Design

    • Full RoHS/REACH/PFAS compliance for EU/US markets.

    • Certifications: ISO 9001:2015, ISO 14001:2015, EN 55032/24 (EMC).

  5. Customization for Critical Applications

    • Thickness options: 0.95mm–6.0mm cover glass.

    • Industrial upgrades: Extended temp ICs, rain-rejection algorithms, EMI shielding.

    • Surface treatments: Ceramic inks (10+ year UV resistance), 2.5D/3D edges.

Target Applications

  • Factory Automation: Control panels, PLC interfaces.

  • Medical Devices: Diagnostic equipment, portable monitors.

  • Transportation: Fleet management systems, EV dashboards.

  • Smart Building: HVAC controls, security terminals.

Why Engineers Choose This Module

*"With 72.3×72.3mm active area and OCA-bonded lamination, this module eliminates optical distortion while surviving ±8kV ESD events. The 40-pin ZIF connector simplifies integration, and our I²C touch interface reduces host MCU load. Customizable for MIL-STD environments."*
