Pixel pitch and display format

The Sostron Foldable LED Poster features a 1.5mm pixel pitch — finer than most LED poster displays on the market — in a slim, freestanding portrait-orientation form factor designed for digital signage and branded content display. This tight pitch produces exceptionally detailed imagery at close viewing distances as short as 4 to 10 feet, making it ideal for upscale environments where image quality is a priority.

Display resolution and image quality

With a display resolution of 640 × 1920 pixels and a size of 4.20ft × 6.30ft, the Sostron LED Poster delivers a tall, high-definition canvas optimized for portrait-oriented content. High-density SMD RGB LEDs and a refresh rate typically at or above 3,840 Hz provide smooth, flicker-free video and still content that performs cleanly in front of cameras and under broadcast lighting. The 1.5mm pixel pitch also provides sharp text, detailed graphics, and smooth gradients across the full display surface.

Brightness and indoor performance

Calibrated for controlled indoor environments, the Sostron LED Poster operates at brightness levels typically in the 800 to 1,000 nit range, providing strong visual impact in ambient lighting conditions found in lobbies, conference centers, trade show floors, and upscale event venues. The 1.5mm pitch allows the display to maintain image integrity at closer proximity than coarser-pitch alternatives.

Portability and self-contained design

The unit is a self-contained freestanding display with an integrated frame, built-in media player, and wheeled base for easy repositioning without additional rigging or hardware. A single power connection is all that is required for operation, making setup and teardown fast and straightforward for rental and event applications.
