Behold the power of LEDs.
For the past year or two, the new high-definition disc formats have been dominating the headlines, but, believe it or not, there have been other developments in the realm of video—or at least in the way video is displayed. One of the newest is the use of LEDs as a light source instead of UHP (ultrahigh-pressure) lamps. Essentially, three tiny LEDs (one red, one green, and one blue) emit the light. Since there's one LED for each of the three primary colors, this eliminates the need for a color wheel. Video editor Geoffrey Morrison covered this technology in depth in his July 2006 GearWorks column (also available online). The benefit is that LEDs are far sturdier than a UHP lamp and should easily last until your next display upgrade, saving you money on replacement lamps. While the theory is that LEDs can run cooler than UHP lamps, at the moment, they can often be rather hot, which can lead to excessive fan noise coming from the back of the television. According to NuVision, the LEDs in the 52LEDLP run cool enough that you could touch them without hurting your hand.
