The WF43WTWAESNN0 is a 4.3-inch IPS TFT display featuring a wide viewing angle (80/80/80/80), ensuring consistent and vibrant colors from any direction. Unlike traditional TN panels, IPS technology provides superior color accuracy and better visibility, making it ideal for industrial control systems, instrumentation, and gaming applications.
This model features a 4-line QSPI interface with direct FPC pinout, which simplifies integration by reducing the number of pins required for data transfer. The direct FPC pinout eliminates the need for complex connectors, providing easier assembly and a more compact design for embedded systems.
With an operating temperature range of -30°C to +80°C, the WF43WTWAESNN0 is built for reliability in harsh environments, ensuring stable performance in industrial and outdoor applications.
