Case analysis of outdoor LCD screen advertising machine application at the seaside 1
Outdoor LCD Screen Advertising Machines face multiple challenges in the seaside environment, such as salt spray corrosion, strong ultraviolet rays, high temperature and humidity, and strong wind. This article analyzes the technical solutions, equipment selection and maintenance experience in different scenarios through three actual cases, and provides reference for related projects.
Case 1: Guide screen of Yalong Bay Seaside Scenic Area in Sanya
Project background
Yalong Bay in Sanya is a famous tropical coastal tourist area in China. It has high temperature and high humidity all year round, and is severely eroded by sea breeze and salt spray. The scenic area management department needs to install information guide screens on the seaside trail to display maps, advertisements and weather warning information.
Environmental challenges
1. High salt spray corrosion: Sea breeze carries salt, which is easy to corrode electronic components.
2. Strong ultraviolet rays: Direct sunlight causes the screen to fade and heat up.
3. Typhoon threat: Strong winds may hit every summer.
Solution
1. Equipment selection
Brand model: LG 55-inch outdoor LED screen (55SVH7C)
Protection level: IP66 (anti-splashing + dustproof)
Brightness: 3000 nits (ensure visibility under direct sunlight)
Casing material: 316 stainless steel + anti-corrosion coating
2. Structural optimization
Wind-resistant design: adopts column installation, the concrete foundation is 2 meters deep, and has passed the wind tunnel test to ensure resistance to level 12 typhoons.
Anti-glare treatment: The screen surface uses frosted tempered glass to reduce reflections.
3. Anti-salt spray measures
- The circuit board is sprayed with three anti-paints (moisture-proof, anti-salt spray, and anti-mildew).
- All interfaces are sealed with silicone to prevent salt spray intrusion.
4. Intelligent management
- Built-in 4G module, supports remote content update and device status monitoring.
- When a typhoon warning is issued, the device can be remotely shut down to avoid damage.
Operation effect
Stability: No serious failures in 3 years of operation, only surface salt stains need to be cleaned every quarter.
Exposure effect: Average daily traffic volume is 15,000, and the click-through rate of advertisements has increased by 20%.
Lessons learned
Insufficient heat dissipation in the early stage: High temperature causes color deviation of the Outdoor LCD Screen Advertising Machines, and a cooling fan is installed later.
Maintenance frequency: The sealing needs to be checked regularly in the salt spray environment, and monthly inspections are recommended.
Case 2: Outdoor LCD Screen Advertising Machines on Barcelona beach
Project background
Barceloneta Beach in Barcelona, Spain is a popular tourist area. Merchants hope to set up interactive Outdoor LCD Screen Advertising Machines for brand promotion and tourist guides.
Environmental challenges
1. Sand and dust erosion: Fine sand can easily enter the interior of the device, affecting heat dissipation.
2. Tourist touch: The screen needs to be impact-proof and fingerprint-proof.
3. Large temperature difference between day and night: High temperature during the day, condensation water at night may affect the circuit.
Solution
1. Equipment selection
- Brand model: Samsung Outdoor LCD Screen Advertising Machines (OH series, 65 inches)
- Protection level: IP65 + anti-riot tempered glass
- Brightness adjustment: 2500 nits (daytime), automatically reduced to 800 nits at night to save energy.
2. Anti-sand and dust design
- A removable dust filter is installed at the bottom for easy regular cleaning.
- A closed heat dissipation duct is used to prevent sand and dust from entering.
3. Interactive function optimization
- Infrared touch technology supports operation in rainy days (capacitive screens are prone to failure in humid environments).
- Oleophobic coating on the screen surface reduces fingerprint residue.
4. Energy management
- Solar panels are integrated on the top to reduce dependence on city electricity, suitable for environmentally friendly scenic spots.
Operation effect
Interactive experience: Visitors' stay time increased by 30%, and advertising conversion rate increased.
Maintenance challenge: Sand and dust blocked the heat dissipation holes in the early stage, and the automatic air blowing cleaning system was changed later.
Experience summary
Anti-sand design needs to be optimized: ordinary filters are prone to clogging, and a self-cleaning solution is recommended.
Night mode is necessary: automatic brightness adjustment can extend the life of the screen.
