Case Description of the Large-Screen Display Project in the Exhibition Hall of Shanghai Jiao Tong University Undertaken by Stonbel
I. Project Background
As a top-tier university in China, Shanghai Jiao Tong University (SJTU) has always been committed to creating high-quality spaces for academic exchange and exhibition. Its exhibition hall serves as a key window to showcase the university’s school-running achievements, scientific research capabilities, campus culture, and development plans to the outside world, thus imposing extremely high requirements on the clarity, stability, and interactive experience of display equipment. To further enhance the exhibition hall’s sense of technology and information transmission efficiency, SJTU decided to upgrade the hall’s display system. After rigorous screening and evaluation, the university finally chose to cooperate with Stonbel, which took charge of constructing the exhibition hall’s large-screen display project.
II. Project Requirement Analysis
The core requirements of SJTU’s exhibition hall for the large-screen display system focus on the following aspects:
Ultra-high definition: It should clearly present various contents such as pictures of the university’s scientific research achievements, academic report PPTs, and campus scenery videos to meet display needs in different scenarios.
Stable and reliable performance: It should operate without faults during long-term use in daily exhibitions, academic exchange activities, and other occasions.
Convenient and efficient control methods: It should allow staff to quickly switch display contents and adjust display effects.
High-quality sound reinforcement system: It should realize synchronized audio and video presentation to enhance the audience’s overall viewing experience.
III. Stonbel’s Solution
Based on the needs of SJTU’s exhibition hall, Stonbel, leveraging its rich project experience and professional technical capabilities, customized an integrated solution that combines high-definition display, intelligent control, and high-quality sound reinforcement.
1. Large-Screen Display Hardware System
Screen Size and Resolution: The display area of the large screen in the project covers 28 square meters, adopting a P1.53 small-pitch LED display screen. This pitch specification ensures display clarity while effectively balancing viewing distance and visual experience—even when viewed up close, it can present delicate, grain-free images. Through precise calculation and splicing, the large screen achieves ultra-high-resolution display, perfectly restoring the details of various display contents. Whether it is complex scientific research data charts or high-definition campus activity videos, all can be clearly presented.
Module Specifications: 320*160mm LED modules are selected. These modules feature high standardization and flexible splicing, allowing precise splicing into the required large-screen size according to the exhibition hall’s spatial structure and display needs. Meanwhile, the high brightness and high contrast of the modules ensure that the large screen presents vivid, realistic color effects under different light conditions. In addition, the modules have the advantages of low power consumption and long service life, effectively reducing the project’s later operation and maintenance costs.
2. Visual Control Platform
To meet SJTU Exhibition Hall’s demand for flexible control of large-screen display contents, Stonbel equipped the project with a self-developed visual control platform. The platform has the following core functions:
Multi-signal source access and management: It supports simultaneous access to multiple types of signal sources, such as computer signals, video signals, image signals, and network signals. Staff can centrally manage all signal sources through the platform, including operations like adding, deleting, naming, and grouping signal sources, facilitating quick search and calling of required signals.
Flexible screen splicing and splitting: The platform provides rich screen splicing and splitting modes. According to display needs, staff can split the large screen into multiple display areas of different sizes (each area displays different contents independently) or splice multiple signal sources into a complete screen for display. This meets the needs of focusing on single-content display or synchronously displaying multiple contents. At the same time, the platform supports one-click switching between different splicing and splitting modes, ensuring convenient and efficient operation.
Real-time preview and control: Through the visual control interface, staff can real-time preview the content of all accessed signal sources and the actual display effect of the large screen, facilitating timely adjustment of display contents and parameters. In addition, the platform supports remote adjustment of parameters such as the large screen’s brightness, contrast, and color saturation, ensuring the large screen is always in the best display state.
Scene saving and recall: For common display scenarios in the exhibition hall (e.g., academic report scenarios, scientific research achievement display scenarios, campus culture promotion scenarios), staff can preset corresponding display plans in the platform and save them as scene modes. In actual use, they only need to recall the corresponding scene mode with one click to quickly switch the large screen’s display content and layout, greatly improving work efficiency.
3. Sound Reinforcement System
To realize synchronized audio and video presentation and enhance the audience’s viewing experience, Stonbel matched the project with a high-quality sound reinforcement system. The system mainly consists of the following equipment:
Speakers: Based on the exhibition hall’s space size and acoustic characteristics, an appropriate number and specification of speakers were carefully selected and installed in a scientifically reasonable layout. The speakers adopt high-fidelity sound design, which can clearly and accurately restore sound signals, ensuring the audience can hear uniform, clear sound (without obvious sound dead zones or distortion) at every position in the exhibition hall.
Power amplifiers: Power amplifiers matching the speakers are equipped to provide stable, sufficient power support for the speakers, ensuring they work normally and efficiently while avoiding equipment damage or sound quality degradation caused by power mismatch.
IV. Project Implementation Process
Preliminary On-Site Survey and Planning: At the beginning of the project, Stonbel dispatched a professional technical team to conduct an on-site survey of SJTU’s exhibition hall. The team measured the hall’s spatial dimensions in detail, analyzed its light environment and acoustic characteristics, and conducted in-depth communication with relevant personnel of the university to clarify the project’s specific needs and timelines. Based on the survey results and demand analysis, the technical team formulated a detailed project implementation plan—including the large screen’s installation location and splicing plan, the control platform’s deployment plan, and the sound reinforcement system’s equipment selection and installation layout plan—and submitted it to the university for review and confirmation.
Equipment Procurement and Inspection: After the project implementation plan was confirmed by the university, Stonbel procured equipment in accordance with the equipment list in the plan. All procured equipment came from formal manufacturers and had valid quality certification certificates. After the equipment arrived, the technical team conducted strict quality inspection and performance testing on all equipment—including display effect testing of large-screen modules, function testing of the control platform, and sound quality testing of the sound reinforcement system—to ensure all equipment met project requirements and quality standards and prevent unqualified equipment from entering the construction site.
On-Site Installation and Commissioning: After the equipment passed the inspection, Stonbel organized a professional construction team to carry out on-site installation and construction in SJTU’s exhibition hall. The construction process strictly followed the project implementation plan and relevant construction standards to ensure construction quality and safety. During the large-screen installation, the construction team performed precise positioning and careful splicing to ensure the large screen was smoothly spliced without obvious gaps. During the control platform deployment, technicians completed software installation, parameter configuration, and system commissioning to ensure the platform’s functions operated normally.
Project Acceptance and Training: After the project construction was completed, Stonbel invited relevant personnel of SJTU to conduct project acceptance. The acceptance covered aspects such as the large screen’s display effect, the control platform’s functions, and the sound reinforcement system’s sound quality. After strict testing and inspection, all indicators of the project met the standards agreed in the contract and passed the acceptance smoothly. After the acceptance, Stonbel’s technical team provided system operation training for the university’s staff—including the use of the control platform, operation skills of the sound reinforcement system, and precautions for daily equipment maintenance—to ensure the staff could proficiently master the operation and maintenance skills of the system
