The EDMGRB8KHF / EDMGRB8KKF series is a 7.8-inch industrial CSTN LCD panel from Panasonic, featuring a VGA 640×480 resolution and a color transmissive STN display mode. This panel is designed for industrial equipment, embedded control systems, HMIs, and legacy applications where simple graphical user interfaces are required without the cost and power consumption of TFT displays.

It uses a parallel data interface and CCFL backlight, making it well suited for systems that were originally designed with CSTN technology or where backward compatibility is desired. The moderate brightness and classic VGA resolution offer readable visuals for control panels and monitoring displays under typical indoor industrial lighting.
