While our previous coverage of Osram at Electronica has focused on the company’s backlighting technology, we found more to discuss this year. The company had a large stand at the front of hall A3 (the dedicated displays area), which literally glowed!
In one corner of the booth we saw a new LED for display boards. As part of Osram’s Displix range, the device was contained in a black package to raise its contrast. Osram uses a narrow wavelength in its LEDs, to provide homogenous light.
Unlike conventional LEDs, the light-emitting area in the Displix Oval (clever name – TA) was an oval shape, rather than square. We were told that this raises the viewing angle, to 110 deg /60 deg .
On the other side of the stand Osram was showing a new blue laser package for projectors, the PLPM4 450. The company manufactures green lasers for pico projectors, but the blue model is much more powerful; it has a 50W output in the blue spectrum (450nm, +/-10nm) , enabling a brightness of about 2,000 lumens.
The PLPM4 450 uses 20 multi-mode laser chips in a single housing; five on each of four copper bars.
