TN Displays for Test Equipment: Custom Industrial LCD Screens | Low-Cost & Durable
Our COB-TN Segment Displays are engineered for test and measurement instruments, offering simple numeric/symbol visualization, ultra-low power consumption, and industrial durability. Combining Chip-on-Board (COB) packaging with Twisted Nematic (TN) technology, these screens provide reliable, cost-effective solutions for handheld devices, benchtop analyzers, and factory-floor testers.
Custom Symbol Integration
Preloaded with common unit symbols (mV, kPa, °C) – reduce development time.
Wide Environmental Tolerance
-20°C to +70°C operation | IP54 sealing optional for dusty/humid environments.
Battery-Friendly Design
0W static power | 3.3V/5V or 2.7V–3.6V support for portable devices.
Industrial Longevity
COB encapsulation resists vibration, dust, and chemical exposure.
