LCD screen empowers intelligent access control innovation

With the acceleration of smart city construction and the upgrading of security requirements, the intelligent access control system is iterating from a single identity verification device to a "visual interactive terminal". As the core interactive carrier, the liquid crystal display (LCD) has become a key force driving the intelligent transformation of the access control system with its advantages of high-definition display, flexible adaptation, and secure linkage, widely penetrating into various scenarios such as office buildings, communities, and financial institutions.
From the early days of simple card readers without screens to today's intelligent terminals with integrated full-color touch screens, the application of LCD screens has completely reshaped the interactive experience and security level of access control systems. Industry data shows that in 2022, the domestic market size of display type induction card access control card readers has reached 3.86 billion yuan, accounting for 31.8% of the overall access control hardware market. Among them, products equipped with LCD displays have maintained a compound annual growth rate of over 19% in shipments due to their visualization advantages, becoming the mainstream choice in the market.

At the functional implementation level, LCD displays endow intelligent access control with the core capabilities of "visible, interactive, and strong linkage". In low-end scenarios, segment code screens and monochrome dot matrix screens achieve basic information feedback with high cost-effectiveness, clearly displaying states such as "authorized", "card invalid", "door opening timeout", etc., and are suitable for cost sensitive scenarios such as community property management and county-level schools; In the mid to high end market, 3.5-10 inch color touch screens are the mainstream, integrating touch operation, real-time preview, multimodal authentication guidance and other functions, greatly improving traffic efficiency and safety.

Mainstream manufacturers have launched intelligent access control products equipped with high-performance LCD screens to accelerate the implementation of technology. The TP-LINK TL-AS8230 intelligent access control all-in-one machine is equipped with an 8-inch LCD touch screen with a resolution of 1280 × 800. It is paired with binocular liveness detection and black light level sensors to achieve fast face recognition in low light environments. It supports multiple authentication methods such as face recognition, card swiping, and password authentication. At the same time, the device status and access records are presented in real time through the screen, which is suitable for high security scenarios such as financial outlets and enterprises. The 4.3-inch LCD touch screen integrates video preview and local management functions with a compact body, and the operation logic is close to that of a mobile phone, making access control equipment debugging and daily control more convenient. It can still maintain accurate recognition in backlit and low light environments.

In the international market, the integration of LCD screens and access control systems also focuses on security and efficiency upgrades. Some brands have launched LCD screen gate systems that provide multilingual operation guidance, real-time queue information, and security alerts through high-definition displays, achieving the dual goals of crowd diversion and permission control in public areas. Their wide viewing angle and high brightness screen design ensure clear and readable information in strong halo environments.

Technological evolution and policy driving inject new momentum into the application of LCD displays in the field of intelligent access control. The breakthrough of domestic chips has reduced the BOM cost of LCD access control terminals by 15% -18%, promoting the penetration of products into county-level markets and small and medium-sized enterprises; The overall layout plan for the construction of Digital China and other policies have strengthened the data retention and compliance requirements of access control systems. LCD screens, as data visualization carriers, have become an important configuration for access control equipment to meet compliance standards. In the future, with the deep integration of AI edge computing and Internet of Things technology, LCD will further break through the single function of "display", become the core perception node in the smart building and zero trust security architecture, realize the deep linkage with video monitoring, visitor management, and emergency system, and build a more efficient and secure new ecosystem of smart traffic.
