Quantenmechanik bietet Alternative zu Leuchtstoffröhren News & Analysis 7/12/2004 Post a comment Möglicherweise werden schon bald neuartige Leuchtkörper aus quantenmechanischen Elementen anstelle von Leuchtröhren unsere Büros beleuchten. Ein Proof-of-Concept-Experiment am Los Alamos National Laboratory und in den Sandia National Laboratories zeigt, dass so genannte Quantenschächte als Basis für Lichtquellen mit einem Wirkungsgrad von fast 100 Prozent dienen können. Das Labor in Los Alamos untersteht der National Nuclear Security Administration, der US-Behörde für atomare Sicherheit.
Fiber Optic Backlight - panels are exceptionally thin Product News 7/6/2004 Post a comment The UniGlo Optima fiber optic backlight from Lumitex offers a high brightness of 30+ Ft-L and more, depending on panel design and configuration. The Optima Technology is twice the brightness of Lumitex's standard UniGlo fiber optic panels " with much improved light uniformity across the panel.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
