Monochrome COB Segment VA Displays for Security & Surveillance Systems

Engineered for mission-critical security applications, our VA (Vertical Alignment) Segment LCDs with COB (Chip-on-Board) technology deliver unmatched durability and clarity in access control panels, intercom systems, and smart locks. Combining VA’s superior contrast, COB’s rugged encapsulation, and anti-tamper features, these displays ensure reliable operation in high-traffic or harsh environments.

Key Features & Specifications

1. Security-Optimized Durability

• IK08 Vandal Resistance: Tempered glass + metal frames withstand deliberate impacts (20J shock tested).

• IP65/IP67 Sealing: Dustproof, waterproof, and chemical-resistant (tolerates cleaning agents, graffiti).

• Wide Temperature Range: Operates at -30°C~70°C (storage: -40°C~85°C), ideal for outdoor intercoms or heated server rooms.

2. High-Visibility Display

• VA Technology: ≥1000:1 contrast ratio with 170° viewing angles, readable under direct sunlight or dim corridors.

• Sunlight Mode: 600 cd/m² backlight (optional) for glare-free outdoor readability.

• Fast Response (≤15ms): Real-time updates for door access logs or intrusion alerts.

3. Secure Integration

• Low Power: ≤5μA standby current (5+ years on backup batteries for wireless locks).

• EMI/ESD Protection: EN 61000-4-2/4-4 compliance (±15kV ESD, 30V/m RF immunity).

• Flexible Interfaces: RS-485, Wiegand, or SPI/I²C for seamless PLC/access control integration.
