Osram launches first surface-mountable LED with oval light-radiating characteristics

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the surface-mountable Displix Oval, which is claimed to be the first LED with oval light-radiating characteristics for large-screen video walls, gas station price signs and digital road signs. The beam angles are 110° (horizontal) and 60° (vertical).

Due to a compact housing measuring just 2.1mm x 2.7mm x 1.5mm (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. The images displayed are hence extremely vivid with a high color homogeneity.

An additional advantage of this high pixel density is that the pixel brightness required is lower, so 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 image quality. This 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,” says product marketing manager Andrew Lin. “A display fitted with the new Displix Oval LEDs has a stable and very homogenous color appearance,” he adds.

Both the processes and the processing of the Displix Oval are much simpler than with radial LEDs, greatly reducing customers’ processing costs, says the firm. Being very flat, the LED requires less silicone for the potting of the boards to protect the contacts from rain, moisture and corrosive outdoor environments. This enables a reduction in the amount of material used, which again has a considerable impact on costs.

The Displix Oval is available in yellow, red, green and blue (with brightnesses at 20mA of 1cd, 1cd, 6cd and 600mcd, respectively).
