Description
WF0840ASWAMLNN0 is an 8.4-inch IPS TFT LCD with a wide operating temperature range and high brightness. It has module dimensions of 199.5 x 149.0 mm, an AA of 170.8032 x 128.1024 mm, and a 1024 x 768 dots resolution. This TFT module is built-in with ST5821AH and ST5084AA driver ICs supporting LVDS interfaces. The LVDS interface is becoming increasingly popular for TFT displays because it is a perfect connecter for the TFT LCD modules requiring high-speed data transmission with low power consumption.
This 8.4-inch TFT model features an IPS panel, having the advantage of wider viewing angles of Left: 80/ Right: 80/ Up: 80/ Down: 80 degrees (typical value), a contrast ratio of 1000:1 (typical value), a high brightness of 1000 nits (typical value). The supply voltage for Logic (VDD) of WF0840ATWAMLNN0 is from 3.0V to 3.6V, with a typical value of 3.3V. It can operate at a wide temperature range from–30℃ to +80℃, and its storage temperature range is from -30℃ to +80℃. This high-brightness TFT module is suitable for test instruments, medical equipment, industrial control equipment, etc.
