H121HHD20I1K001-CT1 is a 12.1 inch TFT LCD module with capacitive touch function. The capacitive touch screen supports multi-touch, has fast response and no pressure required, and is highly sensitive and smooth to operate. This LCD panel uses IPS panel technology to provide full viewing angles and rich display colors. The resolution is 1024×768 (XGA), with moderate pixel density, and the display of text, images and videos is clear and detailed, providing a high-definition visual experience. The LVDS 20PIN interface, with a 900nit high brightness design, can maintain clear display even in outdoor or strong light conditions. It is made of reinforced glass and impact-resistant materials, capable of withstanding external impacts and scratches. The working temperature can withstand -10℃ to +60℃, and can adapt to harsh environments such as industrial and vehicle use.
Key Applications: Professional instruments and testing equipment (oscilloscopes, spectrum analyzers), public information screens, industrial HMI panels, PLC controllers, vehicle transportation, and medical equipment.
