Description

The WFN0400A2T0YAMNN000 720x720 TFT LCD Display Module is a high-performance display solution designed for industrial applications, smart home systems, and various other embedded systems. This 4-inch display features a 720x720 resolution and a circular design, ensuring sharp, clear visuals with exceptional detail, making it an ideal choice for applications that require high-definition display performance.

With IPS technology, the module offers an 85-degree wide viewing angle, providing accurate and vibrant colors from virtually any perspective. The 720x720 display ensures that content is rendered with high clarity, while the high contrast ratio of 1200:1 enhances the depth and richness of the image. The anti-glare surface further reduces reflections, improving visibility and user experience.

Offering a brightness of 350 cd/m², this display module provides consistent, bright visuals in a variety of environments. The MIPI 4-Lane interface ensures fast and reliable data transmission, and the digital supply voltage range of 1.65V to 3.3V (with a typical value of 1.8V) ensures compatibility with a wide range of devices.

For touch applications, the WFN0400A2T0YAMNA000 version is available, which provides the same high-quality display performance but includes a capacitive touch panel, allowing for precise touch interactions in various use cases.

Whether used in smart home products, industrial control systems, or other applications, the WFN0400A2T0YAMNN000 provides reliable, high-quality display performance that enhances the functionality and appeal of your devices.
