In the rapidly evolving world of embedded display technology, engineers in the U.S. and Germany are increasingly seeking compact, high-resolution TFT modules that deliver sharp visuals, fast response times, and reliable optical performance. Saef Technology Limited introduces the SFTO397HD-7133ACT, a 3.97-inch (480×800) TFT LCD module designed for applications demanding exceptional clarity and responsiveness—such as medical devices, industrial HMIs, portable test equipment, and advanced consumer electronics.
With a pixel density exceeding 500 PPI (pixels per inch), this display delivers stunning image quality, making it ideal for applications where fine text, detailed graphics, or high-fidelity UI elements are critical. The active area measures 86.4 × 48.6 mm, maintaining a 16:9 aspect ratio that aligns with standard video and multimedia formats, simplifying content development and integration.
One of the key performance metrics for modern displays is response time, especially in dynamic interface applications. The SFTO397HD-7133ACT achieves a typical response time (Tr+Tf) of 35ms, ensuring smooth transitions between frames and minimizing motion blur—critical for real-time data visualization and video playback.
Optical performance is equally impressive. The module offers a contrast ratio of 550:1 at normal viewing angles, providing deep blacks and vibrant colors. Its transmittance of 5% (with polarizer) ensures efficient light utilization from the backlight system, contributing to power efficiency and brightness uniformity. The viewing angle is 85° in all directions (CR > 10), enabling consistent color and contrast across wide angles—essential for collaborative or multi-operator environments.
The display is built on an IPS (In-Plane Switching) panel, delivering superior color reproduction and stable grayscale performance. This technology is widely recognized in IEEE and SID literature for its ability to maintain color accuracy across varying viewing positions—making it ideal for professional-grade equipment.
Designed for durability and long-term reliability, the SFTO397HD-7133ACT undergoes rigorous testing and adheres to strict manufacturing standards. It is fully compatible with automated assembly processes and supports integration into compact, high-density PCB layouts.
Backed by Saef Technology Limited’s commitment to innovation and quality, this module is an excellent choice for engineers designing next-generation embedded systems that require high resolution in a compact form factor.
