In modern buildings and smart communities, access control systems serve as essential security barriers. As the first interactive point in smart communities, the display and operation experience of door phones directly impact user satisfaction. As public devices used outdoors, their components—displays and touch screens/protective cover glasses—must maintain stable performance in complex outdoor environments. Here are the key points:

Door Phone Displays: Core Requirements and Key Features

The display of a door phone is not only a window for information presentation but also a reflection of its adaptability to outdoor environments. Its main features and requirements are as follows:

• Mainstream Specifications:  5 inch TFT LCD or 7 inch TFT LCD, with resolutions of 800×480 or 1024×600.
• High Brightness: it is required sunlight readable with minimum 500 nits, over 1000 nits required for direct sunlight environments.  
• Wide Temperature Operation: -20℃ to 70℃, adaptable to extreme climates in both northern and southern regions.  
• Wide Viewing Angle:  IPS technology ensures no distortion when viewed from multiple angles.  
• Long Lifespan:  Industrial-grade components support 7×24 hours of uninterrupted operation.  

Door Phone Touch Screens and Cover Glasses: Ensuring Interactive Experience 

If the display is the "brain," then the touch screen and cover glass are the "outposts" that protect the brain and execute commands. They directly determine the operational experience and device durability:

• Touch Screen Type:  Capacitive touch screens have become the main choice, supporting multi-touch, responsive feedback, and optimized algorithms for wet-hand and gloved operation.  
• Anti-Interference: Door phones may be exposed to electromagnetic devices (e.g., intercoms, surveillance cameras). Touch screens must possess strong anti-electromagnetic interference capabilities to prevent touch drift and false triggers.  
• Cover Glass Protection: Chemically strengthened or tempered glass with a Mohs hardness of 6H or higher, offering scratch resistance and impact resistance. Even if broken, it should fragment into small granules to ensure safety.  
• Surface Treatment Process: Anti-fingerprint (AF) coating for easier cleaning; anti-UV and anti-glare features to adapt to outdoor environments. Outdoor door phone covers must be printed with anti-UV ink to prevent yellowing from UV exposure.  
• Customization Capability: Supports customization of size, shape, printing, and openings to meet the cover glass design needs of different products.  

Recommendations for Selecting Door Phone Screens

When choosing a screen for your new door phone, consider the following:

• Scenario Adaptation Priority: For outdoor scenarios, focus on wide temperature range, high brightness, waterproofing, and dust resistance. For indoor scenarios, prioritize low power consumption and narrow bezel design.  
• Quality Over Cost: Choose industrial-grade suppliers to ensure the materials and craftsmanship of displays, touch screens, and cover panels meet standards, avoiding access control failures due to screen malfunctions.  
• Customization Adaptation: Tailor screen size, resolution, cover panel shape, and openings based on the door phone's functions (e.g., video calls, facial recognition) and installation space.
