OD-WS Series vs. OD-SL Series – Which Outdoor LED Module is the Best Fit for You?
In the outdoor LED display market, the OD Series has long been a trusted choice for engineering contractors, system integrators, and end users. Among them, the OD-WS Series and OD-SL Series are especially popular. Both deliver high brightness, IP65 waterproof and dustproof protection, and long-term stable operation, making them suitable for a wide range of outdoor environments.
However, they differ significantly in structural design, installation method, pixel pitch range, and application focus. Understanding these differences will help you make the right selection for your project—whether it’s a space-limited storefront display or a massive stadium screen.
1. Structure & Protection – Fully Enclosed Waterproof Back Cover vs. Screw-Lock Design
OD-WS Series
-
Features a fully enclosed waterproof back cover, with each module measuring 320×160 mm and secured by magnetic screws for easy handling.
-
The front-service structure allows modules to be replaced directly from the front without leaving rear access space, which is ideal for embedded, wall-mounted, or restricted-access installations.
-
IP65-rated protection ensures stable operation under rain, snow, dust, and humidity, making it a reliable choice for various weather conditions.
OD-SL Series
-
Utilizes a robust screw-lock design, directly securing the modules to the frame or cabinet, with weather sealing largely dependent on the installation structure itself.
-
Supports both front and rear maintenance, offering flexibility, but is best suited for use with standardized cabinets to achieve high overall structural strength and anti-deformation capability.
-
Excels in projects that require very large display areas and high structural stability, such as sports stadiums and billboard installations.
2. Specifications & Pixel Pitch – Wide Range vs. Mid-to-Large Pitch Focus
OD-WS Series
-
Pixel pitch options: P2.5 / P3.076 / P4 / P5 / P8 / P10
-
Covers applications from fine-pitch, high-definition close-range viewing to large-scale, long-distance installations.
-
Brightness ≥ 4000 nits (P10 up to 4500 nits) ensures clear visibility even under direct sunlight.
-
High refresh rate up to 3840 Hz delivers smooth and detailed visuals, ideal for high-resolution videos and dynamic advertisements.
OD-SL Series
-
Pixel pitch options: P2.5 / P3.076 / P4 / P5 / P6.67 / P8 / P10
-
Offers fewer small-pitch options but adds P6.67 to provide an optimal balance between clarity and cost for medium- to long-range viewing.
-
Maintains high brightness and refresh rates for stable image performance during sports events, concerts, and other high-traffic outdoor occasions.
-
Well-suited for projects with strict budget control and viewing distances in the mid-to-long range.
3. Installation & Applications – Flexible Creativity vs. Large-Scale Stability
OD-WS Series
-
Lightweight build, magnetic front-service design, and independent waterproof back cover.
-
Highly adaptable to flat, curved, wave-shaped, or other custom surfaces.
-
Ideal for retail storefronts, shopping mall atriums, window displays, public information boards, and exhibition booths—especially in high-traffic areas where quick maintenance is essential.
-
Supports creative and unique display shapes to enhance brand identity.
OD-SL Series
-
Screw-lock and cabinet assembly ensure strong structural stability for very large displays.
-
Perfect for billboards, stadium screens, building façades, and stage backdrops at large events.
-
Standardized cabinet assembly improves installation efficiency and allows for easy modular replacements during maintenance.
4. How to Choose
When deciding between the OD-WS and OD-SL Series, consider viewing distance, installation space, maintenance method, and budget:
-
Close-range viewing (2.5–4 m), limited space, quick front maintenance required
→ Choose OD-WS Series P2.5 / P3.076 / P4. Offers precise image quality and accurate color reproduction, ideal for displaying high-detail ads and information content. Front access reduces the need for rear maintenance space—perfect for shopping malls, showrooms, and shop windows. -
Mid-range viewing (5–10 m), large screens, structural stability required
→ Choose OD-SL Series P5 / P6.67 / P8. Delivers an excellent balance between clarity and cost. The screw-lock design ensures stability under long-term operation and wind load, making it suitable for stadiums, large billboards, and permanent outdoor installations. -
Long-range viewing (10 m+), cost efficiency and visual impact
→ Choose OD-WS Series P8 / P10 or OD-SL Series P8 / P10. Reduces per-square-meter cost while maintaining high brightness and strong color impact. Ideal for municipal boards, large building façades, and stadium exteriors.
Tip:
-
If your project demands creative shapes or has limited installation space, the OD-WS Series is the better choice.
-
If your project is massive in scale and requires cabinet-based assembly with maximum stability, go with the OD-SL Series.
5. Conclusion
Whether you choose the OD-WS Series or OD-SL Series, you can expect:
-
High brightness for clear visibility in direct sunlight
-
High protection level with IP65 waterproof and dustproof rating for all-weather performance
-
High refresh rates for smooth video playback and real-time content display
-
Long lifespan & reliability for continuous operation in commercial and public installations
If your installation site is space-constrained, requires front maintenance, and demands flexibility in display shapes, the OD-WS Series will be your best fit.
If you are building a large outdoor billboard, stadium screen, or any project requiring cabinet assembly and strong structural integrity, the OD-SL Series is the better choice.
