Reliable, Cost-Effective Touch Display Solution for Demanding Embedded Applications

Saef Technology Limited presents the SF-TC350H-8812A-T, a robust 3.5-inch TFT LCD module engineered for applications where durability, simplicity, and reliability are paramount. Featuring a 320×480 resolution, integrated resistive touch panel, and a widely supported 16-bit parallel interface driven by the ILI9488 IC, this module is ideal for industrial HMIs, medical devices, point-of-sale systems, and embedded control panels.

Engineered for Stability & Ease of Integration:

• Proven Resistive Touch Technology: With over 1,000,000 input cycles and linearity within ±1.5%, this RTP delivers reliable performance in environments where capacitive touch may be less suitable, such as gloved operation or dusty conditions.

• Wide Operating Temperature Range: Certified for -20°C to +70°C operation and -30°C to +80°C storage, ensuring consistent performance in challenging environments.

• Simple Interface & Low System Overhead: The 16-bit parallel interface reduces development complexity and is compatible with a wide range of microcontrollers and embedded processors, speeding up time-to-market.

• Optical Performance Tailored for Readability: 300 cd/m² brightness and 250:1 contrast ratio provide clear visibility in typical indoor and industrial lighting conditions. The 12 o’clock viewing direction optimizes display orientation for vertical-mounted applications.

Technical Specifications for Design Consideration:

• Power Supply: VDD = 2.8V ±0.2V, IOVCC = 1.8V–2.8V

• Backlight: White LED edge-lit, 19.2V typical forward voltage (20mA drive)

• Touch Panel Ratings: X-axis resistance 300–900Ω, Y-axis 200–500Ω; operating voltage ≤7V DC

• Mechanical Outline: 54.48mm × 84.71mm × 3.25mm (max)

• Compliance: Designed to meet industrial reliability standards with testing for high/low temperature, humidity, thermal shock, and vibration resistance
