Industrial-Grade 2.1-Inch Round Touch Display with 2.5D Asahi Glass & Dual Interface
Engineered for demanding environments, this high-definition round LCD screen delivers 480×480 pixel clarity within a compact 2.1-inch circular active area. Protected by 2.5D Asahi Glass with 6H surface hardness, it withstands scratches, impacts, and frequent operation in industrial, medical, and outdoor applications.
Featuring a versatile 3SPI/18RGB dual-interface design, it seamlessly integrates into both low-pin microcontroller systems and high-performance processor-based platforms. The integrated capacitive touch panel (CST820 IC, I²C interface) ensures reliable, glove-compatible interaction, while the ST7701S-driven TFT offers wide viewing angles and 262K color reproduction.
Built with a ZIF connector for secure connections and an ultra-slim 3.72mm profile, this module is ideal for HMI panels, portable instruments, IoT controllers, and wearable medical devices where durability, clarity, and touch responsiveness are critical.
