Specialized category for liquid crystal displays (LCD) integrated into manufacturing production equipment and control systems. Handles LCD displays specialized for visual information display in manufacturing sites, including NC machine tool operator panels, automation equipment monitoring screens, control panel built-in displays, industrial touch panel LCDs, HMI (Human Machine Interface) LCDs, and factory digital signage. Product lineup features high reliability required for industrial applications such as environmental resistance (dustproof, waterproof, vibration-resistant), wide temperature range operation, long-term continuous operation support, and high brightness/high contrast specifications. Clearly distinguished from LED displays and plasma displays, limited to display devices adopting liquid crystal technology (TN, STN, TFT methods).
