Description

WF40ETWAA6DNN0 is a 4 inch Square IPS TFT-LCD module; made of resolution 480 x 480 pixels. This module supports 24-bit RGB interface, it featured with IPS panel which is having the advantage of wider viewing angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical), contrast ratio 800:1 (typical value), 500 nits (typical value), glare surface panel, aspect Ratio 1:1. If customers require high brightness, you can consider to choose our WF40ESWAA6DNN0 (1000 nits). This model is also available in projected capacitive touch panel (PCAP) and resistive touch panel (RTP).

WF40ETWAA6DNN0 is integrated driver IC ST7701S on module, the interface supply voltage range from 2.5V to 3.6V, typical value 2.8V. WF40E model can be operated at temperatures from -30℃ to +80℃; its storage temperatures range from -30℃ to +80℃.
