Frequently Asked Questions
What does 2500-4000 cd/m² brightness mean for outdoor visibility?
A brightness level between 2500 and 4000 cd/m² (nits) provides ultra-high luminance, ensuring that the screen content remains crystal clear, readable, and vivid even under direct, harsh sunlight.
What is the difference between the 43" and the 55"/65"/75" resolutions?
The 43-inch model features a Full HD (1080 × 1920) resolution, which is sharp for closer viewing distances. The larger 55-inch, 65-inch, and 75-inch models feature ultra-crisp 4K UHD (2160 × 3840) resolutions to maintain high pixel density across larger physical screen dimensions.
Why are these displays configured in a 9:16 aspect ratio?
The 9:16 portrait orientation is standard for digital totems, outdoor kiosks, and vertical commercial advertising, allowing optimal formatting for mobile-friendly content and vertical video displays.
What is the advantage of a 4000:1 contrast ratio?
A high static contrast ratio of 4000:1 delivers deeper blacks, brighter whites, and richer color depth, preventing washed-out imagery in bright ambient lighting conditions.
How do I determine the right screen size (43" to 75") for my project?
The 43" and 55" models are ideal for pedestrian walkways, retail storefronts, and indoor/semi-outdoor kiosks. The 65" and 75" models offer maximum visibility for drive-thrus, transport hubs, plazas, and larger open spaces where viewers are located further away.
What color capability do these display panels support?
All models support 16.7 million colors (8-bit color depth), providing natural color gradations, accurate brand image representation, and vibrant multimedia playback.
