Description

The WF40CTYAQMNG10 is a 3.97-inch portrait orientation IPS TFT-LCD display module, offering a resolution of 480 x 800 pixels. This module is equipped with an ST7701S TFT driver IC and supports a MIPI DSI serial interface (2 lanes). The portrait screen configuration, ideal for vertical applications, provides excellent flexibility for designing small, space-efficient industrial displays. It also features a larger glass cover for enhanced durability and protection, making it suitable for more demanding environments.

With an IPS panel that delivers wide viewing angles (Left: 80° / Right: 80° / Up: 80° / Down: 80° typical), a contrast ratio of 900:1, and a minimum brightness of 400 nits, this display ensures sharp visuals and clarity, even in environments with moderate ambient light. The portrait screen format is particularly well-suited for applications such as handheld devices, small industrial equipment, and security monitoring systems, where vertical display arrangements are preferred for better readability and usability.

Equipped with a Projected Capacitive Touch Screen supporting 5-point multi-touch, this module offers a precise and responsive touch experience. The touch panel is integrated with a GT911 driver IC that supports the I2C interface, enhancing the overall touch performance for a seamless user experience. The optical bonding technology used in the PCAP panel increases durability and improves optical clarity, making this portrait screen module ideal for long-lasting, high-performance applications.

Operating at a supply voltage range of 2.8V to 3.3V, the TFT module supports a wide temperature range from -20°C to +70°C for operation and -30°C to +80°C for storage, ensuring its reliability in a variety of environments. Perfect for vertical applications such as dash cameras, this module brings superior display quality to small devices and industrial systems, with the added advantage of an enhanced glass cover for additional protection and durability.
