In the field of rail transit, clear and reliable information display directly affects the travel experience of passengers. A high-definition LCD display will also improve customers’ favorability towards the overall equipment. With its breakthrough technical indicators, RisingStar industrial sunlight readable display is becoming the preferred solution for more than 30 large and medium-sized railway stations around the world. When peer products barely maintain 3000nits brightness under the midday sun, our direct backlight technology has achieved a peak brightness of 5000nits. Combined with the all-aluminum frame weight reduction design and adaptability to extreme environments of -20℃~60℃, the railway station Sunlight Readable passenger information display system is more popular with passengers.

Customers’ proven value

The project director of a railway bureau gave feedback: “In the rainstorm test, the fully waterproof structure of the whole machine was completely unafraid of the storm and was still clearly visible, while the three brands tested at the same time had varying degrees of water vapor penetration. In particular, the 46-inch large screen did not show any brightness decay after 30 days of continuous operation, thanks to your 48-hour aging screening before leaving the factory.”

Six key factors for customers to choose the RisingStar brand

In demanding application scenarios such as rail transit and smart cities, professional customers choose RisingStar industrial Sunlight Display leggibile screens mainly based on the following core advantages:

1. Industry-leading optical performance
   5000nits ultra-high brightness technology, 66% higher than the industry standard, ensures clear images in strong light environments
   Using a direct-type backlight module to achieve an ultra-high contrast ratio of 4000:1, and increase the text recognition distance by 40%
2. Industrial-grade reliability design
   The all-aluminum frame structure is 30% lighter than traditional iron and has stronger impact resistance
   Passed the -20℃ to 60℃ extreme temperature cycle test (8 hours/time, far exceeding the industry’s conventional 2-hour standard)
   IP65 fully waterproof whole machine design, which can withstand continuous invasion of heavy rain for 12 hours
3. Ultra-long service life guarantee
   50,000 hours of service life
   The original heat dissipation system reduces the operating temperature by 15℃, effectively delaying light decay
4. Modular intelligent design
   Open architecture supports fast maintenance, and the unit replacement time is shortened to 15 minutes
   Reserved multiple interface expansion slots, compatible with various system interfaces
5. Proven operational benefits
   Actual cases show that the average annual number of failures is reduced by 82%
   Energy consumption is reduced by 22% compared with similar products, and 100 units can save about 3,800 degrees of electricity per yea
