Description

Engineered for Demanding Applications: The 2.8-Inch Transflective TFT LCD Module

At Saef Technology Limited, we specialize in developing high-performance display solutions for engineers and system designers who require reliability, clarity, and flexibility in challenging environments. Our 2.8-inch Transflective TFT LCD Module (SFTO280PY-7422AN) is built to excel in both bright outdoor settings and low-light indoor conditions—making it the ideal choice for handheld meters, portable instruments, industrial HMIs, and medical devices.

Key Design Advantages for Engineers:

  • Superior Optical Performance in Any Light

With a 300 cd/m² high-brightness backlight and a transflective display technology, this module ensures excellent readability under direct sunlight while maintaining low-power operation in dim environments. The 500:1 contrast ratio and 60° wide viewing angle provide consistent visual quality from all orientations.

  • Dual Interface Flexibility: MCU & SPI

Designed for seamless integration, the module supports both 8080-series MCU parallel (8/16-bit) and SPI (3/4-wire) interfaces. Driven by the robust ST7789T3 controller, it offers fast response times (16ms typical) and stable communication for real-time applications.

  • Wide Operating Temperature Range

Rated for -20°C to +70°C operation and -30°C to +80°C storage, this display is built to withstand extreme conditions—perfect for outdoor, automotive, and industrial systems.

  • High Reliability & Longevity

The 4-LED edge-lit backlight delivers an average lifetime of 40,000 hours, while the module undergoes rigorous environmental testing including vibration, ESD (±8kV air/±4kV contact), and thermal cycling to ensure durability in the field.

  • Fully Customizable & Ready for Integration

We offer free technical support and semi-custom design services—including touch panel integration (RTP/CTP), connector options, firmware tuning, and mechanical adaptations. Whether you need a drop-in module or a tailored display solution, our engineering team is here to help.

Technical Specifications at a Glance:

  • Display Area: 43.2 x 57.6 mm

  • Pixel Pitch: 0.06 (H) x 0.18 (V) mm

  • Color Depth: 262K

  • Power Supply: 2.8V (VCC), 1.8V (IOVCC)

  • Dimensions: 50.0 x 69.2 x 2.3 mm

  • Weight: Optimized for portable designs

  • Compliance: RoHS, REACH, ISO 9001:2015, ISO 14001:2015
