8.4 1024x768 IPS LVDS TFT Display Module with Capacitive Touch Screen (High Brightness) RFM08400A-AW

8.4" 1024x768 IPS LVDS TFT Display Module with Capacitive Touch Screen (High Brightness)

Model No. RFM08400A-AWH-LNB

RFM08400A-AWH-LNB is a 8.4-inch, IPS TFT LCD module with capacitive touch screen. The resolution is 1024x768 pixels and the aspect ratio is 4:3. This TFT display uses ST5821AH and ST5084AA driver IC which supports LVDS Interface (Low Voltage Differential Signaling). The module adopts IC EXC81W32 for PCAP touch supporting USB interface (I2C available) and 2-point touch.

The module features wide viewing angle (80/80/80/80) thanks to the IPS panel which is one of the most popular techniques on the market now. It also features high brightness, high contrast and wide temperature , providing brightness 800 cd/m2, contrast ratio (typical value) 1,000:1, Works within temperature range from-30 to +80℃, Storage Temperature covers from-30 to +80℃.
