Under the rapid iteration of digital technology, exhibition halls have moved from the traditional "static model of graphic and textual display boards" mode to a new digital form that is intelligent, interactive, and immersive. As the core support of the exhibition hall, multimedia equipment integrates cutting-edge technologies such as LED display, holographic projection, AI interaction, and digital twin, breaking down one-way information transmission barriers and building a deeply interconnected experience scene of "human device space", becoming the core carrier for government and enterprise brand display, cultural inheritance, and technology popularization. Decoding the application and value of modern exhibition hall multimedia equipment from four dimensions: core equipment, technological innovation, application scenarios, and development trends.

1、 Core display device: Creating a stunning visual core

Display devices are the foundation of information transmission in exhibition halls, and are developing towards ultra-high definition, lightweight, customized, and transparent directions, adapting to the visual needs of different scenes.

LED large screen matrix: The mainstream adopts P1.2-P2.5 small pitch modules, supporting 4K/8K ultra high definition display, with a brightness of over 1500nit, compatible with HDR10 standard, with bright colors, wide viewing angles, and long lifespan. The application forms are flexible and diverse, including ultra large LED screens for theme areas, curved/ring screen LEDs for creating immersion, flexible LED screens adapted to building structures, and textured screens that can simulate wood grain and marble textures, perfectly integrating into spatial decoration.

Transparent and holographic display equipment: The transparent LED screen has a light transmittance of over 85%, supports 4K display, can be overlaid with physical exhibits, displays the internal structure and dynamic information of the product, and achieves "virtual real symbiosis"; The holographic projection cabinet adopts 180 °/360 ° imaging technology to achieve naked eye 3D effect, with an imaging accuracy of 0.01mm. It is commonly used for displaying cultural relics and high-end product 3D models, and supports gesture rotation and scaling; Holographic light field technology can also restore cultural relics, buildings, etc. in a 1:1 ratio, allowing the audience to "touch" the details of virtual exhibits.

Engineering Projection System: Brightness ≥ 6000 lumens, supports edge fusion and surface correction, can project onto walls, floors, sand tables, and irregular surfaces. Multi channel projection fusion technology can achieve seamless connection of images and create a 150 ° curved immersive scene; Alien projection can project images onto sculptures and building facades for dynamic restoration of cultural relics, artistic scene creation, and more.

2、 Intelligent interactive devices: from passive viewing to active participation

Interactive devices are the key to bringing exhibition halls to life, relying on technologies such as touch, gestures, voice, and AI recognition to transform audiences from "spectators" to "participants" and achieve personalized interactive experiences.

Touch interaction terminal: The capacitive touch all-in-one machine supports multi touch with more than 20 points, with a response speed of ≤ 5ms. It can perform operations such as zooming, dragging, and clicking, and is used for navigation queries, product demonstrations, and information browsing; The interactive slide screen combined with track sensing technology can move in a straight or curved line, automatically stop and trigger interactive content, commonly used for brand history and storytelling display; The transparent touch screen does not obstruct the exhibits behind, allowing the audience to view information such as cultural relic introductions and 3D model disassembly by touch.

Immersive interactive devices: The interactive projection system includes ground interaction, Hogwarts interactive wall, etc. The audience's body movements can trigger dynamic light and shadow, special effects animation, and are commonly used in science museums and children's exhibition halls; VR/AR devices create a scene crossing experience, VR devices achieve virtual scene immersion, and AR technology superimposes virtual information on real images, such as virtual car test drives and AR restoration of cultural relics; The digital sand table combines projection and physical models, and interacts with buttons, laser pens, or tablets to dynamically display urban planning, real estate layout, industrial park planning, and more.

AI intelligent interactive device: The AI digital person is equipped with a large language model and a multimodal interaction system, supporting voice, gesture, and eye tracking. It can interact with the audience in real time and answer questions accurately with a response accuracy of 98%, becoming a new standard for intelligent guided tours in exhibition halls; The AI curation brain is based on a large model and knowledge graph, which can automatically adjust the exhibition content and depth of explanation according to the audience's age and interests, achieving personalized exhibition experience; The full scene perception network uses millimeter wave radar and environmental sensors to capture real-time audience stay time and interaction preferences, providing data support for content optimization.

3、 Central control and audio-visual equipment: Building a strong intelligent base for the exhibition hall

The central control system is the "nerve center" of the exhibition hall, and the audio-visual equipment creates an immersive atmosphere. The two work together to ensure the stable, efficient, and intelligent operation of the exhibition hall.

Intelligent central control system: adopts the "cloud side collaboration" architecture, with core computing power on the cloud, edge computing processing real-time interaction, and lightweight terminal deployment. It can centrally control all multimedia devices in the exhibition hall, achieve one click switch, content switching, volume adjustment, fault warning, support remote management and scheduled tasks, and significantly reduce operation and maintenance costs.

Professional audio-visual system: surround sound creates an immersive auditory experience, directional sound can avoid sound interference with other exhibition areas, and adapt to the sound effects needs of different exhibition items; High definition audio processors, wireless microphones, and other devices ensure clear and stable explanation and interactive voice, combined with AI voice recognition technology, to achieve functions such as voice control devices and voice query information.

4、 Typical application scenario: Technology empowers diverse display needs

Multimedia devices have been widely used in government and enterprise exhibition halls, museums, science and technology museums, planning halls, cultural and tourism exhibition halls, and other scenes, adapting to different exhibition themes and needs.

Enterprise Exhibition Hall: Display brand promotional videos and development history on LED screens, showcase product parameters and cases on touch all-in-one machines, present core technology 3D models on holographic screens, provide intelligent guidance with AI digital humans, and showcase the layout of enterprise parks on digital sand tables to comprehensively convey brand strength.

Museum/Cultural Exhibition Hall: Holographic projection restores the original appearance of cultural relics, transparent screens display the internal structure of cultural relics, interactive sliding screens tell historical stories, AR devices restore ancient life scenes, making cultural inheritance more vivid and easy to perceive.

Science and Technology Museum/Planning Museum: Environmental projection creates immersive scenes for space exploration, urban future, etc. Interactive projection and VR devices provide interactive science popularization experiences. Digital sand tables dynamically display urban planning and geographic information, helping science popularization education and planning exhibitions.

The iteration of multimedia equipment in exhibition halls, from single display to multi-dimensional interaction, from static display to immersive experience, is essentially a deep integration of technology and experience. In 2026, with the continuous breakthroughs in AI, digital twin, and holographic technologies, exhibition halls will become intelligent spaces that integrate brand communication, cultural experience, data insights, and commercial transformation, bringing audiences a more shocking, personalized, and warm visiting experience, and injecting new vitality into government and enterprise brand display and cultural dissemination.
