From "Listening to the Intercom" to "Watching the Intercom", intelligent LCD modules usher in a new era of visual intercom systems

With the rapid development of smart communities and digital homes, the traditional building intercom system is undergoing a profound visual and intelligent transformation. The traditional intercom door units and indoor units, which were dominated by simple buttons and monotonous voices, are now being replaced by LCD display modules that integrate high-definition display, multi-point touch control and multi-functional integration, becoming the "first screen" connecting families and community smart services. 
Technical Upgrade: The Leap from Feature Phones to Smart Terminals 
The early building intercom devices had limited display areas and were functionally simple. The introduction of the new LCD display module has brought about a fundamental change: 
· High-definition visual interaction: Utilizing TFT-LCD or high-end IPS modules, with a resolution of up to 720p or even 1080p, ensuring clear and realistic images of visitors and a modern and aesthetically pleasing interface design.
· Integrated touch control: Seamlessly integrating the capacitive touch screen with the display module to achieve smooth sliding and tapping operations, completely replacing physical buttons. The appearance is more concise and the experience is more technologically advanced.
· Strong expansion capability: Modern liquid crystal display modules usually come with high-performance processors. They not only can run the intercom system but also can support a wide range of applications such as facial recognition, QR code unlocking, mobile remote connection, community information release, and smart home control. 
Market-driven: The demand for intelligent security solutions and value-added services 
Industry analysis indicates that this round of upgrade is mainly driven by three major demands: 
1. Security upgrade necessity: High-definition video intercom has become a standard feature in mid-to-high-end residential complexes, playing a crucial role in enhancing community security levels.
2. Digital management of property: Through the LCD screens of the entrance machines and indoor units, the property management can efficiently issue notifications, announcements, and advertisements, reducing communication costs and generating additional profits.
3. Users' expectations for improvement: Owners, especially the younger generation, expect to have an interaction experience as smooth and intuitive as that of smartphones, and view the intercom system as the entry point for smart home technology. 
Application scenario deepening: Beyond "opening the door" 
The intercom system equipped with advanced LCD display modules has evolved from a simple "access control communication device" to a "community comprehensive information terminal": 
· Doorphone: Enables face recognition for opening the door, virtual access card system, visitor photo and message recording, and elevator call (联动) functions.
· Indoor unit: Owners can view real-time monitoring of public areas such as unit doors and elevator lobbies at any time； receive property information；联动 control smart devices like lights， curtains， and air conditioners in their homes； and even conduct online shopping， payment， and other community O2O services. 
Supply Chain and Challenges 
In response to this trend, the upstream LCD display module suppliers are actively adjusting their product lines and developing modules that meet the special requirements of the building intercom industry: featuring wide temperature operation, high brightness (adapted to strong outdoor light), long lifespan, low power consumption, and providing an open and friendly software interface to assist the complete machine manufacturers in rapid development. 
Of course, the industry also faces challenges such as cost control, interconnection of different brand devices, data security and privacy protection. This requires all links in the industrial chain to work together to promote the formulation of standards and technological research and development. 
Future Outlook

Industry experts predict that as display technology continues to shrink and costs are further optimized, the penetration rate of liquid crystal display modules in the building intercom field will continue to increase. In the future, "super intelligent display terminals" that integrate more complex sensors (such as millimeter-wave radar sensing) and artificial intelligence algorithms will become possible, providing safer, more convenient and more comfortable services for smart communities.
