Against the backdrop of accelerated construction of new energy infrastructure around the world, RisingStar, as an industrial-grade display solution provider, has launched a 75 inch high brightness display dedicated to charging piles, which is popular among global customers for its 5000nits peak brightness and industrial-grade reliability.
1. Customer installation and use feedback
A leading charging network operator said after purchasing:
1. Modular design enables fast installation, and the all-aluminum frame is 35% lighter than the traditional solution
2. 5000nits peak brightness increases the scanning and recognition success rate to 99.8% during the noon period
3. 24-month operation data shows that the failure rate is less than 0.3%, far exceeding the industry average of 3%
2. Customer selection reasons
1. Exclusive direct backlight technology, brightness range 2500-5000nits
2. Industrial-grade 1200:1 contrast ratio, visibility under strong light is 400% higher than ordinary screens
3. 50,000-hour life certification, passed -20℃~60℃ extreme temperature difference cycle test
4. Back reinforcement rib + IP65 waterproof whole machine design, resistant to typhoon level 12 wind pressure
75-inch industrial-grade high brightness display technical specifications analysis
Core parameters and advantages comparison
Optical performance
1. 3000cd/m² brightness: exceeds consumer-grade TV (200-1500cd/m²), close to professional digital signage display standards, and adapts to strong direct light environments
2. IPS full viewing angle & 1200:1 contrast: compared with VA panel products, color uniformity is improved by 40%, and 178° blind spot visibility meets multi-viewing interaction needs
3. RGBW pixel layout: white light sub-pixels are added on the basis of ordinary RGB structure, and energy efficiency ratio is optimized by 18%
Industrial reliability
1. -20~60℃ storage temperature: breaking through the 0~40℃ limit of conventional consumer electronics, passing the 8-hour extreme temperature difference cycle verification, each device must run continuously for 24h-48h before packaging before leaving the factory
2. Direct-type WLED backlight system: 50,000 hours of life cycle is 2.3 times longer than the side-entry backlight
3. Matte + 2H hardened coating: 80% less reflective interference than glossy screen, anti-scratch level reaches MIL-STD-810G standard
Key technical points
1. Weight control: 27.6kg bare screen weight is 22% lighter than traditional metal frame solution
2. Power consumption performance: Energy consumption is less than 180W at 3000nits brightness, 57% energy saving compared to DLP solution with the same brightness
3. Signal compatibility: VESA DisplayHDR 1400 certified, supports HLG/PQ dual HDR format
