Surface-mounted LED doubles pixel density
The surface mountable Displix Oval is an LED developed by Osram Opto Semiconductors with oval light-radiating characteristicsfor large-screen video walls, petrol station price signs and digital road signs. 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 colour 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 colour 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,” explained Andrew Lin, product marketing manager at Osram Opto Semiconductors. “A display fitted with the new Displix Oval LEDs has a stable and very homogenous colour appearance.”
