Designed for Demanding Applications: Precision, Performance, and Reliability

Saef Technology Limited introduces the SFTO310HZ-7423A-CT, a high-performance 3.1-inch TFT LCD module engineered for professionals who demand exceptional optical clarity, rugged reliability, and seamless integration. This IPS display delivers 480×800 resolution with 302 PPI, ensuring sharp, vibrant visuals ideal for handheld devices, industrial HMIs, medical instruments, and portable test equipment.

Key Technical Highlights for Design Engineers:

  • Superior Optical Performance: With 450 cd/m² luminance and 1000:1 contrast ratio, this module ensures readability in both dim and brightly lit environments. The IPS technology guarantees consistent color and clarity across wide viewing angles (80°+).

  • Robust Touch Integration: Featuring a projected capacitive touch panel with multi-touch support and I²C interface, it offers smooth, responsive interaction. The cover glass is chemically strengthened with ≥6H hardness for scratch resistance.

  • Industrial-Grade Durability: Operating temperature range of -20°C to +70°C and storage up to -30°C to +80°C makes it suitable for harsh environments. The module complies with RoHS, REACH, and halogen-free standards.

  • Flexible Interface & Power: MIPI DSI interface reduces EMI and simplifies board layout. Wide power supply range (VDD: 2.4V–3.3V, IOVDD: 1.65V–3.3V) supports various system architectures.
