Osram Opto Semiconductors has launched an LED with oval light-radiating characteristics for large-screen video walls, gas station price signs and digital road signs: the new surface-mountable Displix Oval. Thanks to a compact housing measuring just 2.1 x 2.7 x 1.5 mm (including lens), almost twice as many LEDs can now be mounted on a board than with ordinary radial diodes, doubling both the pixel density and the resolution of displays. As a result, the images displayed are extremely vivid with a high color homogeneity.
An additional advantage of this high pixel density is that the pixel brightness required is lower so that the individual LEDs require a lower current. In combination with the durable housing materials, this lower output extends the lifetime of the diodes.
The Displix Oval has a black QFN (Quad Flat No Leads) housing, which further increases the image quality. It reduces reflections and increases the contrast and color quality of the images displayed across the entire display.
Both the processes and the processing of the Displix Oval are much simpler than with radial LEDs, greatly reducing customers' processing costs. Being very flat, the Displix Oval requires less silicone for the potting of the boards to protect the contacts from rain, moisture, and corrosive outdoor environments. This enables customers to reduce the amount of material used, which again has a considerable impact on their costs. The Displix Oval will be available in October 2014 in yellow, red, green and blue.
