Real-World Applications of OPL 7 Inch TFT LCD Displays

 

Industrial Control: The "Nerve Center" of Smart Factories

 
OPL’s industrial-grade 7 inch modules serve as HMI terminals for PLC control systems and smart meters. Their 1000 cd/m² brightness ensures visibility in dusty workshops, while the -30°C to 85°C wide temperature range adapts to extreme production environments. A automotive parts manufacturer reported 30% higher operational efficiency after upgrading to OPL’s modules for real-time production data display.
 

Medical Equipment: Precision in Patient Care

 
The medical-grade series is integrated into portable diagnostic devices for rural clinics. Its high-resolution display (1280×720) clearly renders ultrasound images, and the anti-glare surface prevents eye strain during long shifts. OPL’s modules also support quick data export to electronic health records via USB interface.
 

Automotive Electronics: Reliable On-the-Road Displays

 
For in-vehicle use, OPL’s 7 inch modules power navigation systems and rearview monitors. They pass IEC 60068 vibration tests and feature 800 cd/m² brightness to combat sunlight glare. The low-power design (typical 2.2W) extends vehicle battery life compared to generic alternatives.
 

Smart Home: Intuitive Living Control

 
In smart home hubs, the standard series provides touch-enabled interfaces for lighting, security, and HVAC control. Its compact size (165×100mm) fits wall-mounted panels, and the 5-point capacitive touch supports gesture operations like swiping and zooming.
 

Why Choose OPL 7 Inch TFT LCD Modules?

 

1. Customization Tailored to Your Needs

 
OPL offers end-to-end customization:
 
  • Resolution adjustment (800×480 to 1920×1200)
  • Interface adaptation (RGB/LVDS/MIPI) and touch panel options (resistive/capacitive)
  • Housing design to fit unique device enclosures
  • Brightness tuning (250 cd/m² to 1000 cd/m²) for specific environments
 

2. One-Stop R&D & Manufacturing
