For engineers focused on miniaturization without compromising performance, the SFTO397HD-7133ACT from Saef Technology Limited offers a compelling solution: a 3.97-inch Full HD TFT LCD that packs 1920×1080 resolution into a space-saving footprint—ideal for portable, battery-powered, and high-end industrial devices.
What sets this module apart is its exceptional pixel density and optical clarity. At approximately 507 PPI, it rivals smartphone-grade displays, enabling crisp rendering of text, icons, and complex UI elements. This makes it particularly suitable for applications in medical diagnostics, handheld instrumentation, and AR/VR secondary displays, where visual precision is paramount.
The 35ms typical response time (Tr+Tf) ensures fluid motion handling, reducing ghosting in fast-updating interfaces. Combined with an 85° viewing angle in all directions (CR > 10), the display maintains readability and color consistency even when viewed from extreme angles—critical for wall-mounted or shared-use devices.
Unlike lower-end TN panels, the SFTO397HD-7133ACT uses IPS technology, which provides superior color accuracy and grayscale inversion stability. According to studies published in the Journal of the Society for Information Display (JSID), IPS panels offer up to 30% better color consistency across viewing angles compared to twisted nematic alternatives—making them the preferred choice for professional applications.
The 550:1 contrast ratio enhances visual depth, while the 5% transmittance (with PL) indicates optimized light efficiency, allowing designers to balance brightness and power consumption effectively.
Mechanically, the module is designed for high-volume manufacturing, with a standard FPC interface and compatibility with automated optical inspection (AOI) systems. Its compact size (95.0 × 58.0 × 1.6 mm typical) allows integration into sleek, modern enclosures without sacrificing screen real estate.
With RoHS and REACH compliance, the SFTO397HD-7133ACT meets stringent environmental regulations in both the EU and North America.
Saef Technology Limited continues to push the boundaries of display technology, offering engineers a reliable, high-performance solution for cutting-edge embedded designs.
