Today, with the average daily passenger flow of rail transit exceeding 10 million, traditional visualizzazione informazioni passeggeri screens are facing three major challenges: 23% of passengers complain that they cannot see the arrival information clearly in strong light environments, the platform equipment failure rate is 20 times/unit per year, and the delay in dynamic content updates causes 15% of the schedule changes to be unable to synchronize in real time. The 28-inch visualizzazione informazioni passeggeri system launched by RisingStar Intelligent Display is based on industrial-grade LCD modules. Through peak 5000 nits adaptive dimming and IP65 protection level, key information is always clearly visible in heavy rain and scorching sun.

Customer application effect feedback

A city bus company deployed 300 sets of 28-inch high-brightness LCD information screens in 2024, covering BRT rapid bus lines and subway connecting lines.

1. The accuracy of dynamic arrival forecasts reached 98%, and the number of passenger inquiries decreased by 62%. Through remote unified management, the dispatch center shortened the response time of equipment failure to within 2 hours.
2. Elderly passengers particularly appreciate the 28-inch large font display mode, The questionnaire survey shows that passenger satisfaction has increased from 81% to 94%.

The core reasons why customers choose RisingStar 28-inch display:

1. Extreme environment adaptability‌

Passed -20℃ to 60℃ extreme temperature cycle test to ensure stable operation in extremely cold/high temperature environment

The all-aluminum frame structure is 35% lighter than iron, while improving heat dissipation efficiency

2. Optical performance advantage‌

Direct backlight technology achieves 5000 nits peak brightness (industry average is about 2000 nits), and still maintains 4000:1 high contrast under strong light

70,000 hours of life (similar products are about 50,000 hours), reducing long-term replacement costs

3. Industrial-grade reliability‌

24-48 hours of aging test before leaving the factory, reducing the early failure rate by 90%

Fully waterproof whole machine design (IP65) meets the needs of outdoor heavy rain and dust scenes

4. Energy efficiency and maintenance advantages‌

Backlight adjustment reduces power consumption by 35%, and the surface temperature is controlled within 45℃

Modular design supports 3-minute quick maintenance, significantly reducing downtime losses

RisingStar 28 Inch Passenger Information Display Core Technology

1. Breakthrough in Optical Performance‌

AMVA3 Drive Mode‌
Adopting vertical alignment VA optimization technology, it achieves 4000:1 native contrast ratio (transmissive) in the normally black display mode, surpassing the dark field performance of conventional IPS panels (about 1500:1), and with 72% NTSC color gamut, it ensures the layering of digital signage in strong light environments.

Enhanced Anti-Environmental Interference‌
The 28% haze hardened coating (3H hardness) combined with 700cd/m² ultra-high brightness can maintain more than 85% visibility under 70,000 lux direct light, meeting the EN 45545-2 fire protection standard for outdoor rail transit screens.

Backlight Synchronization Technology‌
The combination of 120Hz panel + 120Hz backlight scanning eliminates visual residue caused by LED flickering, passes CIE 170-2010 low blue light certification, and is suitable for long-term viewing scenes.

2. Industrial-grade reliability design‌

Wide temperature range driving circuit‌
Using low-temperature polysilicon TFT compensation technology, it maintains ≤15% brightness attenuation at -20℃ (conventional LCD reaches 35%), and ensures color shift ΔE<3 at 60℃, which meets the MIL-STD-810G military test standard.

Signal integrity guarantee‌
LVDS dual-channel 8bit interface (2×65MHz) supports 1920×360@60Hz lossless transmission, and 51pin terminal achieves 10KV ESD protection.

3. Special scene adaptation‌

Strip screen cutting optimization‌
The 698.4×130.95mm effective display area is matched with RGB vertical strip pixels, and a ≤0.5mm physical seam is achieved when horizontally spliced, which perfectly adapts to the arc installation requirements of subway dynamic maps.

Energy Efficiency Management System‌
12V low-voltage drive combined with WLED matrix dimming, the power density is only 18.7W/dm², which saves 52% energy compared to CCFL backlight solutions and meets Energy Star 8.0 certification requirements.
