The WFN0400A2T0YAMNA000 is an innovatively designed 4-inch touch screen display module with a 720x720 resolution, delivering clear and detailed visuals on a round screen. This makes it ideal for applications requiring a unique display form factor and high resolution.
This 4-inch touch screen TFT LCD module features IPS technology, offering an ultra-wide viewing angle of 85°/85°/85°/85°. This ensures vibrant and clear images, regardless of the viewing angle. With a typical brightness of 320 cd/m² and a high contrast ratio of 1200:1, the display is exceptionally bright and highlights details more effectively.
Built-in FL7703 TFT driver IC and supporting 4-Lanes MIPI DSI interface, the module allows for high-speed data transmission while maintaining high resolution, ensuring smooth visual performance. The 4-Lanes MIPI interface not only provides fast data transfer but also reduces power consumption, which is essential for devices that need to run for extended periods.
On the touch functionality side, the WFN0400A2T0YAMNA000 is equipped with a Projected Capacitive Touch Panel (PCAP) and incorporates Optical Bonding technology. Optical bonding enhances touch sensitivity and significantly improves display clarity. By removing the air gap between the display module and the touch panel, this technology improves optical transparency, reduces reflections, and ensures faster touch response with clearer visuals.
Additionally, the module supports 4-point touch and features an FT3269 touch driver IC along with an I2C interface, making it easy to integrate with various systems and ensuring stable touch performance.
The WFN0400A2T0YAMNA000 4-inch TFT LCD screen display combines a unique round design, excellent display performance, and advanced touch technology. With the 4-Lanes MIPI DSI interface and Optical Bonding technology, this display module not only provides superior display quality but also offers efficient data transmission and enhanced durability. It is perfect for applications in industrial, smart home, and other fields.
