S I G N & D I G I T A L G R A P H I C S • January 2019 • 21 Fine pixel (higher resolution) pitch SMD LED displays are the future of outdoor digital signs. Just a few years ago, an SMD outdoor LED display with a 6.667mm pixel pitch was impressive. However, this past year at ISA, attendees saw the next-generation outdoor displays with a tighter pixel pitch of only 3.9mm. Recall that the lower the pixel pitch number, the closer together each pixel is, meaning that higher resolutions are possible. Additionally, there are indoor products with a very low .95mm pixel pitch and visuals that look crisp—even from just a few feet away. This is becoming necessary because LED dis- plays, billboards and spectaculars are now in closer proximity to pedestrian traffic and require even higher resolution. These technological advances allow for tremendous versa- tility in many verticals. One example of this is in the recently opened Spartanburg, South Carolina-based FR8yard, a vibrant beer garden with authentic German beer tables with benches. To enhance patrons' experience, a 10' x 16', 6.667mm pitch modu- lar SMD LED display was installed and can be seen from a 160° horizontal viewing angle, important for this venue. And, because much of the programming will be sporting events, the display's 60fps and fast refresh rate provide smooth video playback, as if the viewers were watching on a stadium's jumbotron. The exterior display has weatherproof features, including waterproof modules that are certified IP65/IP54, making it resistant to harsh external elements like rain, wind, dust and heat. Heat Dissipation Advances For billboards and large-scale spectacular displays, air flow management is critical to achieve a long-lasting display. Proper ventilation is key for the display to be successful. One advantage of modular cabinets is that each cabinet is smaller and has an individual rear ventilation system, allowing for faster cooling. Therefore, massive fans aren't needed to circulate air through a large cabinet cavity. Modules that are warmer can exhaust and, because other cabinets are running cooler, power is reduced and fans only activate to push out excess air. Heat sensors and on-board diagnostic utilities help regulate tempera- tures so the display works more efficiently. Additionally, there is less noise compared to larger front-ventilation cabinet designs. Located in Ocean Isle, North Carolina, this 16mm pixel pitch, 12' x 48' LED digital billboard is com- prised of 64 LED module cabinets and is factory assembled in sections for easy installation.
