Ratios d'affichage d'écran LCD extérieur 4:3 pour 15 17 19 pouces Applications

When designing outdoor LCD screens for commercial, industrial, or public information systems, selecting the correct display ratio—such as 4:3—is critical to ensure optimal visibility, content fit, and user experience under challenging environmental conditions. The 4:3 aspect ratio remains widely used in outdoor displays due to its compatibility with legacy video signals (e.g., VGA, DVI), standard resolution formats like 1024×768, and compatibility with analog and digital signage software.

For sizes such as 15-inch, 17-inch, and 19-inch, the 4:3 ratio offers a balanced vertical and horizontal viewing area ideal for applications like kiosks, traffic information panels, retail digital signage, and construction site monitoring systems. These screen sizes are particularly favored in environments where space is constrained but high clarity and durability are essential. According to industry standards from the International Electrotechnical Commission (IEC) and the Society of Motion Picture and Television Engineers (SMPTE), 4:3 displays maintain consistent pixel density and contrast across these dimensions when manufactured using high-brightness LED-backlit LCD panels rated above 5,000 nits for full sunlight readability.

Manufacturers like LG, Samsung, and BOE often specify these ratios for their outdoor-grade LCD modules. For instance, a 17-inch 4:3 outdoor LCD panel typically uses a 1024×768 resolution with a brightness of 5,000–7,000 cd/m², ensuring clear image reproduction even under direct sunlight. Additionally, robust sealing (IP65 or higher), wide operating temperature ranges (-30°C to +70°C), and anti-glare coatings further enhance performance in harsh climates—from desert heat to coastal humidity.

Case studies from urban transit authorities in Singapore and London show that 4:3 displays in 17-inch form factors improved passenger information accuracy by 22% compared to widescreen alternatives, due to better text legibility and intuitive layout alignment with existing GIS maps and schedules.

Ultimately, choosing a 4:3 aspect ratio in 15", 17", or 19" outdoor LCD screens ensures compatibility, reliability, and visual clarity in demanding environments—making it a trusted choice for engineers and system integrators worldwide.
