High TNi 110℃ industrial LCD panel avoiding blackening issue with direct sunlight
LCD panels exposed to direct sunlight suffer from temporary blackening defect. RS550ENT-N25 High TNi 110℃ 55" 4k sulight readable digital signage displays use a special ultra-high brightness panel that can withstand surface temperatures up to 110°C with no blackening defect occurring.
Ultra HD resolution and high brightness
With an Ultra HD resolution and a great brightness of 2,500 cd/m², RS550ENT-N25 clearly deliver contents and attract public attention, which is the ultimate display for outdoor visibility.
Auto Brightness Control
The screen brightness is automatically adjusted depending on the ambient light. The brightness is increased in light for better visibility, while it is decreased in darkness for efficient power management.
Polarizing sunglasses visible
LCD panels use QWP technology to improve visibility
Wearing polarized sunglasses does not affect visual effect
