**YUEQING, CHINA** - Yueqing Bolong LCD Technology Co., Ltd. (Bolong LCD), an established high-tech manufacturer specializing in industrial liquid crystal displays and embedded module solutions since 2010, today announced the strategic expansion of its dedicated **Chip-on-Board (COB) LCD Module** manufacturing lines and custom embedded design division. The expanded production infrastructure enhances Bolong's capacity to supply ultra-stable, anti-interference character and graphic COB display modules to global equipment manufacturers across smart grid systems, industrial automation, medical diagnostics, and new energy infrastructure.
Engineered for Harsh Industrial and Electrical Environments
In modern industrial automation and power grid applications, display modules are frequently exposed to severe electrical noise, high electromagnetic interference (EMI), mechanical shock, and wide ambient temperature fluctuations. Low-grade commercial consumer displays often suffer from flickering, frozen segments, communication errors, and premature driver IC degradation when subjected to continuous electrical stress.
Bolong LCD's COB module architecture directly resolves these operational vulnerabilities. By utilizing heavy-duty epoxy glob-top encapsulation to bond controller ICs directly onto rigid, multi-layer industrial PCBs with integrated ground plane shielding, Bolong's COB modules deliver superior mechanical rigidity and robust electromagnetic compatibility (EMC), guaranteeing continuous 24/7 operating stability.
Standard & Bespoke COB Module Portfolio
Bolong LCD operates two specialized business divisions: one focused on LCD glass matrix cells (pen-segment, TFT color, COG, and OLED screens) and the second dedicated to complete liquid crystal modules (LCM), circuit board engineering, and embedded firmware development. The expanded COB series encompasses a comprehensive standard catalog as well as full non-standard custom development:

Quality governance is enforced at every phase under ISO9001, SGS, and RoHS certifications:
**Automated Optical Inspection (AOI)**: 100% inspection for segment contrast consistency, pixel uniformity, and backlight chromaticity.
**100% 24-Hour High-Temperature Burn-In Testing**: Every batch undergoes continuous burn-in at elevated ambient temperatures (45°C) to eliminate infant mortality defects.
**Environmental Chamber Stress Testing**: Validated across wide operating temperatures (-20°C to +70°C) and extended storage ranges (-30°C to +80°C).
Agile Prototyping and Direct Global Supply
With products actively exported across Europe, North America, South America, and Southeast Asia, Bolong LCD offers streamlined support for OEM engineering teams. Custom hardware prototyping is completed within **10 business days** following technical blueprint sign-off, supported by flexible volume lead times of **2 to 3 weeks** for standard configurations.
