The WFN0210A2T0YADNN000 is a 2.1-inch 480x480 round TFT display with IPS panel, featuring wide viewing angles (85/85/85/85) and consistent image quality. With a typical brightness of 450 cd/m² (380~450 cd/m²) and a contrast ratio of 1000:1, the display ensures reliable visibility under moderate lighting conditions.
This display module utilizes the ST7701 IC for display driving, supporting both 3-wire SPI and 18-bit RGB interfaces for flexible system integration. Its anti-glare surface enhances readability, while the square active area of 53.28 x 53.28 mm offers a true circular display zone, ideal for modern round-interface designs.
With a compact profile of 56.18 x 59.71 x 2.3 mm, the module is easy to integrate into space-constrained enclosures. It is well-suited for applications such as smart home devices, HVAC systems, industrial control panels, and other products requiring a stylish and reliable round display.
