4.0 inch TFT display, 720x720, MIPI, Industrial LCD Screen, 250cd/m²

This 4.0 inch is developed with a standard 720x720 high-resolution IPS screen and MIPI interface. A 4-inch small-sized, round TFT display is perfect for applications requiring both compactness and a unique design aesthetic. This type of display is commonly used in smartwatches, automotive instrument clusters, medical devices, and smart home controls. Its circular shape offers a distinctive look while maintaining full functionality, making it ideal for interfaces that display key information like speedometers, health metrics, or control dials. With vibrant colors, sharp contrast, and wide viewing angles, this display ensures excellent readability from various perspectives, while its small size allows for seamless integration into space-constrained devices or dashboards.
