When selecting a display for compact human-machine interfaces (HMI), portable devices, or industrial instrumentation, every millimeter and milliwatt counts. The SF-TS177H-8784A-N from Saef Technology Limited is a 1.77-inch TFT LCD module engineered to meet these precise demands. This blog unpacks the technical specifications that make this module a standout choice for engineers seeking a balance of performance, size, and efficiency.
Core Specifications for System Integration
At its heart, this module features a 128 (RGB) x 160 resolution TFT panel, delivering crisp and clear graphics for status readouts, icons, and basic user interactions. The display utilizes an 8-bit MPU parallel interface, a widely supported standard that simplifies connection to a vast range of microcontrollers without the need for high-speed serial interfaces, thus reducing firmware complexity.
A key parameter for portable applications is power consumption. The module operates from a 2.8V ±0.3V supply, with a typical supply current of less than 5mA for the logic. This low-voltage, low-current operation is crucial for extending battery life. The integrated white LED backlight, with a typical luminance of 250 Cd/m² at 40mA, ensures excellent readability in various lighting conditions while offering simple brightness control via a resistor or potentiometer.
Robustness for Demanding Environments
Reliability is non-negotiable. The SF-TS177H-8784A-N is designed to withstand an operating temperature range of -20°C to +70°C and storage temperatures from -30°C to +80°C. Furthermore, it complies with rigorous reliability testing standards, including high/low-temperature operation and storage, humidity tests, and thermal shock cycles. This ensures stable performance even in challenging environmental conditions, a critical factor for automotive, industrial, and outdoor applications.
Mechanical and Optical Performance
The module's compact outline dimensions of 33.9mm x 44.05mm x 2.4mm make it ideal for space-constrained designs. Optically, it boasts a contrast ratio of 500:1 and wide viewing angles of 60 degrees (horizontal) and 45 degrees (vertical), providing a consistent image from different perspectives. With a fast response time of 6ms, it effectively handles dynamic content without noticeable smearing.
For designers and engineers, the SF-TS177H-8784A-N from Saef Technology Limited presents a reliable, efficient, and compact display solution backed by comprehensive technical documentation and quality assurance.
