For engineers designing battery-powered portable electronics, every milliampere-hour counts. The choice of display, often the largest power consumer, is therefore a critical decision that impacts battery life, product size, and overall reliability. The 2.8-inch TFT LCD Module SFT0280PY-7200BCT is engineered specifically to meet these challenges, offering an optimal blend of low power consumption, a simple interface, and proven ruggedness.
Engineered for Extended Battery Life
Power efficiency is designed into this module's core. The display logic operates from a 2.8V supply, compatible with modern low-power microcontrollers. More importantly, the 4-wire SPI interface requires far fewer GPIO pins than a parallel RGB interface and allows the host processor to remain in a low-power sleep mode, only waking to update the frame buffer when necessary. This drastically reduces the system's overall power footprint.
The backlight unit, a common power drain, is also optimized. It uses only four high-efficiency LED dies, achieving a bright 300 nits output at a typical current of just 60mA. With a maximum current of 80mA, it provides headroom for high-brightness scenarios while maintaining efficiency. The long LED lifetime of 40,000 hours to 50% brightness ensures the display will not dim prematurely over the product's lifespan.
Built to Withstand Real-World Use
Reliability is not an afterthought. Saef Technology Limited subjects the SFT0280PY-7200BCT to a comprehensive suite of environmental tests, guaranteeing performance in tough conditions. The module is rated for operation from -20°C to +70°C and storage from -30°C to +80°C. It also passes rigorous tests for high temperature and humidity (60°C, 90% RH), thermal shock, vibration, and ESD (±8kV air, ±4kV contact), ensuring resilience against static discharge and physical stress.
Simplifying the Design-In Process
The combination of a simple 4-wire SPI for display, a standard I2C for capacitive touch, and a compact outline makes this module exceptionally easy to integrate. Engineers can save valuable design time, reduce layer count on the main PCB, and select a smaller, more power-efficient host processor. By choosing the SFT0280PY-7200BCT, developers can accelerate their time-to-market for portable, battery-dependent devices without compromising on display quality or long-term reliability.
