FAQ

Q1. What type of systems is this 2.1-inch round TFT suitable for?

This display is designed for embedded systems, industrial controllers, smart instruments, and compact devices that benefit from a circular UI layout.

Q2. Does the round TFT support both MCU and SoC platforms?

Yes. With RGB and SPI interface options, it can be integrated with a wide range of MCUs and SoCs depending on system architecture and performance requirements.

Q3. Is this display suitable for outdoor or semi-outdoor use?

The high luminance and contrast make it suitable for semi-outdoor environments, such as control panels exposed to ambient light, though direct sunlight conditions should be evaluated at system level.

Q4. Can this display be customized for OEM projects?

Customization options such as interface configuration, brightness tuning, and mechanical adaptation are typically available for OEM and ODM projects.

Q5. Is this round TFT intended for consumer-grade products?

This model is primarily designed for industrial, embedded, and professional applications rather than short-lifecycle consumer electronics.
