WG192128C is a monochrome 192x128 graphics module designed for high-precision visual output. Featuring a 3.36-inch diagonal display, this COB (Chip on Board) graphic LCD module integrates a PCB and screw holes for easy installation. Built with the RA6963 controller IC, it serves as a replacement for the WG192128A. The module has an outline dimension of 102.3 × 86.0 mm and an active area of 71.02 × 47.34 mm. It operates reliably in a wide temperature range from -20℃ to +70℃.
This graphics module is ideal for industrial control systems, medical equipment, and other applications that demand clear and stable graphic data display.
