WF0840ATWAMLNN0 is an 8.4-inch Wide Temperature IPS TFT-LCD module made of resolution 1024x768 pixels. This module is built-in with ST5821AH and ST5084AA driver ICs, and it supports LVDS interface. WF0840ATWAMLNN0 is adopted IPS panel which is having the advantage of wider view angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical), contrast ratio 1000:1 (typical value), brightness 500 nits (typical value), anti-glare surface panel, aspect ratio 4:3. If customers need a High Brightness version, please choose WF0840ASWAMLNN0.

The supply voltage (VDD) of WF0840ATWAMLNN0 is from 3.0V to 3.6V, the typical value of 3.3V. It can be operating at temperatures from -30℃ to+ 80℃ and storage temperatures from -30℃ to +80℃.  WF0840A series has a projected capacitive touch panel module no. WF0840ATWAMLNB0 and WF0840ASWAMLNB0 (High Brightness version) for options.

Mitsubishi announced that it would end production of TFT-LCD modules manufacturing. Customers can choose our WF0840ATWAMLNN0 as a replacement for Mitsubishi 8.4” P/No. AA084XB01.
