MX-121FL20BFH-C14

12.1 inch LCD Touch Screen MX-121FL20BFH-C14 is an outdoor-grade touch display module featuring a 12.1" 1280x800 IPS TFT with 1000 cd/m² high brightness and a 20 pin LVDS interface for easy integration with industrial systems. The 12.1 inch LCD display is equipped with an independent LED constant-current driver board (LED-0101/0202) to maintain stable, uniform backlight output during long-time operation. The G+G projected capacitive touch is OCR optically bonded to the LCD, which improves sunlight readability, reduces internal reflection, and enhances mechanical robustness. Using an EETI waterproof-capable touch controller, this 12.1 inch LCD touch screen can still respond under water drops or wet-hand operation, making it suitable for marine displays, outdoor HMI, EV charging stations, kiosks, outdoor agricultural machinery, and other high-humidity or seaside applications.
