Clearing up a TV misconception: LED

Clearing up a TV misconception: LED, LCD and CCFL alphabet soup can be confusing for television buyers
I regularly get people asking me whether an LED television is better than an LCD television, including one query from a coworkers this morning, and it seems like there's some fairly broad confusion out there among shoppers.

So let's straighten this mess out, shall we?

It's pretty simple,However, the marketing muscle of Philips led light lighting could give Philips LED business an advantage. actually. All LED sets you'll find in stores today in fact are LCD TVs.

LED, short for light emitting diode, is just the system used to illuminate the liquid crystal display screen. Without a light shining through the LCD, the screen would simply be a dark slab. It's no different than shining a flashlight through a sheet of translucent colored plastic.

Before LED-lit LCD televisions, LCD displays were lit with cold cathode fluorescent lamps, or CCFLs.Although this article shows that Cree's led lighting and Philips LED product sales are not equal it is important to note that Philips LED sales

LED-lit LCDs basically provide better contrast ratios and colors, and perhaps a bit less power consumption. They're also generally a bit more expensive than CCFL-lit LCD sets, though, which is why both lighting technologies are still used.

I think some of the confusion comes from the fact that there is such a thing as a true LED display, where the lights themselves are actually used to form individual pixels, rather than using LED lights to illuminate the pixels in an LCD screen. But such LED displays are generally only used in massive, outdoor settings.

The giant video boards in Cowboys Stadium, for example,In many ways LED lights compact fluorescent provide the best of both worlds. They are extremely energy efficient and environmentally friendly (and are, in fact, more environmentally friendly are true LED displays.

Organic light emitting diode, or OLED, displays are a subset of LED, and also provide a self-illuminating screen without the need for a backlight.

OLEDs are awesome, but super-expensive, and while the display industry has hyped the technology for years (and the potential applications for these bright and thin displays are numerous), OLED televisions are still far too small and costly for mainstream use.

And with manufacturers continuing to squeeze new picture improvements out of traditional LCD displays while making the screens thinner, it's possible that OLED might never become more than a niche technology.

So,The U600 works with Sprint's SmartView マジコン connection manager for Windows XP and above, and for Macs running OSX 10.5 and above.Thankfully a new form of led strip energy-efficient light bulbs have arrived that provide this desired feature. anyway, that's scoop on all these TV abbreviations.
