The WF40ETWAA6DNN0 is a 4-inch square IPS TFT-LCD module with a 480 x 480 pixel resolution, supporting a 24-bit RGB interface. This module integrates the ST7701S driver IC, ensuring superior performance with fast response times and precise color rendering. The IPS panel provides the advantage of a wider viewing angle: Left: 80°, Right: 80°, Up: 80°, Down: 80° (typical), along with a contrast ratio of 800:1 (typical), a brightness of 500 nits (typical), and an aspect ratio of 1:1.
Thanks to the ST7701S driver, the module delivers outstanding reliability and stability across various applications, with an interface supply voltage range from 2.5V to 3.6V, typically 2.8V. This driver ensures the module operates effectively within a wide temperature range, from -30°C to +80°C, with a storage temperature range of -30°C to +80°C.
The WF40ETWAA6DNN0 is a standard brightness model, also available with a Projected Capacitive Touch Panel (PCAP) under the model number WF40ETWAA6DNG0.
For applications requiring high brightness (1000 nits), customers can choose the WF40ESWAA6DNN0 or the WF40ESWAA6DNG0 (PCAP).
