The first surface-mountable LED with oval light-radiating characteristics
Displix Oval from Osram Opto Semiconductors sets new standards in LEDs for outdoor displays
In our everyday lives, we encounter outdoor displays in a variety of different forms. Osram Opto Semiconductors is now launching the first LED with oval light-radiating characteristics for large-screen video walls or 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, 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 the high density is the fact that a lower pixel brightness is now required so that the individual LEDs take 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 additionally boosts the image quality. It reduces reflections and increases the contrast and color quality of the images displayed – across the entire display: “Being surface mounted, SMT LEDs like the Displix Oval have very low tilt tolerances per diode. A display fitted with the new LEDs hence has a stable and very homogenous color appearance when viewed from virtually any angle,” explained Sven Weber, responsible for the product marketing of the Displix Oval at Osram Opto Semiconductors.
Both the processes and the processing of the Displix Oval are much simpler than with radial LEDs, greatly reducing customers’ further processing costs. Being very flat, the Displix Oval requires less silicone for the potting of the boards to protect the contacts from rain and moisture. This enables customers to reduce the amount of material used, which again has a considerable impact on their outlays. The Displix Oval will be available from October 2014 in the colors yellow, red, green and blue.
