Description

WF40ESWAA6DNN0 is a High Brightness 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), high brightness 1000 nits (typical value), glare surface panel, aspect Ratio 1:1. If customers don’t require high brightness, you can consider our WF40ETWAA6DNN0 (500 nits). This model is also available in projected capacitive touch panel (PCAP) module number WF40ESWAA6DNG0 and resistive touch panel option WF40ESWAA6DNT0.

WF40ESWAA6DNN0 module 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℃.
