Description

The WF40ESWAA6DNG0 is a high-brightness 4-inch square TFT LCD display module, featuring a projected capacitive touch panel (PCAP). With a resolution of 480 x 480 pixels, this square LCD display ensures vibrant colors and high-quality visuals. Thanks to its typical brightness of 800 nits and a contrast ratio of 800:1, the module provides clear, sharp, and stable images even in bright lighting conditions, making it ideal for outdoor displays, portable devices, and industrial control systems.

Equipped with the ST7701S driver IC, this square TFT display supports a 24-bit RGB interface, ensuring efficient operation with a supply voltage range from 2.5V to 3.6V (typical 2.8V). It also has a wide operating temperature range of -30℃ to +80℃, ensuring reliable performance in various environmental conditions.

For touch-enabled applications, the WF40ESWAA6DNG0 integrates the ST1633I PCAP driver IC, supporting the I2C interface and enabling 5-point capacitive touch for responsive user interaction.

This square TFT LCD panel is particularly well-suited for industrial control systems, portable measurement instruments, outdoor display systems, and home automation panels. With its 800 nits brightness, it ensures clear readability in most lighting conditions, providing stable and reliable performance where extreme brightness is not essential. The 4-inch square form factor makes it a versatile display solution for a variety of compact and portable devices.
