Introduction
As embedded systems become more interactive and power-aware, display selection plays a crucial role in product success. The SF-TC350H-9496G-T from Saef Technology Limited is a 3.5-inch TFT LCD that excels in both areas. Let’s explore how its features align with real-world design challenges.
Ideal for Industrial and Medical Devices
With a wide operating temperature range (-20°C to +70°C) and high brightness (420 cd/m²), this display is well-suited for industrial HMIs, patient monitors, and portable diagnostic devices. Its 12 o’clock viewing direction ensures optimal readability in vertical-mounted applications.
Low-Power Operation for Portable Devices
The module’s LED backlight operates at only 15mA, making it an excellent choice for battery-powered equipment. Combined with the ILI9488 driver’s efficient power management, it helps extend device runtime without compromising display quality.
Resistive Touch Support for Interactive UIs
The integrated resistive touch interface (via XL, XR, YU, YD pins) allows for easy implementation of touch-based controls. This is particularly valuable in applications where buttons or sliders are preferred over capacitive touch, such as gloved operations in industrial settings.
Ease of Integration with MCU Systems
The module supports both 16-bit and 18-bit MCU interfaces, offering flexibility in system design. The pinout includes standard control signals such as /WR, /RD, CS, and RS, simplifying communication with popular microcontrollers from vendors like STMicroelectronics, NXP, and Microchip.
Optical Performance in Detail
With a typical contrast ratio of 700:1 and a transmittance of 6.1%, the display delivers vibrant colors and deep blacks. The 25ms response time ensures smooth scrolling and animation, while the wide viewing angles maintain consistency across different viewing positions.
Built to Last
The display undergoes rigorous reliability testing, including thermal cycling, humidity exposure, and high-temperature storage. These tests ensure that the module performs consistently in demanding environments, from factory floors to outdoor kiosks.
Conclusion
The SF-TC350H-9496G-T is a reliable, efficient, and versatile display solution that meets the needs of modern embedded systems. Its combination of optical performance, touch support, and environmental durability makes it a smart choice for engineers and designers across industries.
