Product Description

 

The S040HWV19NN-FC10-AF is a purpose-built 4.0-inch square IPS touch display engineered for smart home interfaces and embedded control systems. Featuring a 480×480 resolution optimized for intuitive UI layouts, it delivers crisp, consistent visuals across 80° full viewing angles (U/L/D/R) — ideal for wall-mounted panels, thermostats, and home automation controllers.
 
Equipped with PCAP capacitive touch technology (G+FF structure) supporting 5-point touch, the display integrates OCA optical bonding to minimize reflections and enhance touch precision, while an anti-fingerprint (AF) coating ensures long-term clarity in high-frequency use scenarios. Powered by the reliable ST7701S display driver IC and FT5446 touch chip, it offers seamless connectivity via MIPI DSI (display) and I2C (touch) interfaces, enabling quick integration with mainstream Linux/Android SoCs to accelerate product development cycles.
 
Built for daily reliability, the display boasts 270 cd/m² typical brightness, 800:1 contrast ratio, and a wide operating temperature range of -20°C to +60°C, with RoHS compliance . From smart home touch panels and lighting controllers to energy management systems and access control interfaces, it combines compact design, smooth interactivity, and robust performance to elevate modern smart living experiences.
