Adhering to ISO 9001, CE, and RoHS standards, our products feature full-dot-matrix drive architecture and seamless microcontroller compatibility. They have been applied in 10+ countries, serving hundreds of clients in industrial automation, power instrumentation, and medical equipment, with CE, FCC, and RoHS certifications for global reliability .

Technical Definition & Classification

Dot-matrix graphic LCD screens are full-dot-matrix drive components supporting custom patterns, icons, and mixed text-graphics display, built on STN/FSTN/FFSTN monochrome technologies. As a core industrial display component, it enables flexible visual output for automation and equipment modernization . Our product line includes two main series: Standard Resolution Series (122×32 to 320×240, cost-effective for general use) and Wide-Temperature Industrial Series (-20℃~+70℃, customizable to -40℃~+85℃, for harsh environments) . We follow a design philosophy of high reliability, easy integration, and long lifespan to meet industrial site demands .

Technical Principle & Core Advantages

Our screens operate on full-dot-matrix drive architecture with a built-in control chip, converting host controller signals to precise pixel control for flexible display output. Compared to traditional fixed-character screens, our products offer two key verified advantages: 1. Flexible Custom Display: Eliminates fixed-output limitations, supporting custom graphics and mixed content to meet diverse visual needs . 2. Legacy Compatibility: Directly works with old industrial controllers, reducing replacement costs and integration complexity by up to 60% . Additionally, our industrial-grade construction ensures anti-electromagnetic interference and 50,000+ hour backlight lifespan, maintaining stable performance in field and industrial settings .
