WF40CTYAQMNN0 is a 3.97-inch IPS TFT-LCD display module with a resolution of 480 x 800 pixels. The WF40C module supports a MIPI DSI Serial interface (2 lanes) and features an IPS panel, providing a wider viewing angle of Left:80 / Right:80 / Up:80 / Down:80 degrees (typical), a contrast ratio of 900:1 (typical value), and a brightness of 600 nits (typical value). The panel has a glare surface, enhancing brightness performance in darker environments by reflecting more light and contributing to improved visibility. Additionally, a glare surface helps maintain color saturation, making displayed images vibrant and realistic. The display surface typically incurs fewer light losses, enhancing the overall efficiency of the display.
This 3.97-inch MIPI LCD display operates in portrait mode and integrates the driver IC ST7701S on the module. The interface supply voltage range is 2.8V to 3.3V. The TFT module can operate at temperatures ranging from -20°C to +70°C, with storage temperatures ranging from -30°C to +80°C. It is suitable for small industrial equipment, security monitoring systems, handheld devices, and applications such as dash cameras.
