Plasma TV vs. LCD TV , Part III

Television Life Span

Again, LCD vs. Plasma, and LCD comes out ahead in regards to life span. Plasma TVs generally have a life span of 20,000 - 30,000 hours according to manufactures. This compares to around 50,000 - 80,000 hours for the LCD backlight. Also, since Liquid Crystal Televisions use a backlight, this backlight can be replaced on some models if needed. Assuming 4 hours of viewing per day, a Plasma TV will last approximately 13 years, compared to an LCD TV that would last around 25-40 years. In either case, you will likely get a lot of viewing pleasure out of both types.

Mitsubishi's LaserVue 65-inch and 75-inchers due this fall

We got a first glimpse of Mitsubishi's brand new rear-projection-ish laser-based TV tech, LaserVue, back at CES, but now the sets are just about primed for action, and should be hitting store shelves, as previously noted, Q3 2008. LaserVue will debut in 65-inch and 73-inch, with the 65-inch version hitting the scene first. Mitsubishi is still pretty coy about what exactly makes the technology tick -- other than the "zomg, lasers" aspect -- but is quick to point out the 200 percent color gamut that LaserVue provides, more than twice that of most traditional HDTVs. The sets also run at 120Hz, and boast 500 nits of brightness. Head to head against LCD and plasma sets we had trouble finding the differences, other than the color depth (particularly in the reds, almost too much so, though we're sure you can tweak that). Have no fear: the blacks are black, the brights are bright, and the viewing angle puts DLP to shame. That said, we're hearing price points are going to be more comparable to plasma and LCD than DLP, so Mitsubishi might have its work cut out for it in convincing consumers that these new "chubby," 10-inch thick TVs are the way to go. We're not entirely convinced ourselves, though one aspect can't be disputed: LaserVue draws under 200 watts, about half that of LCD and a third of plasma.

Best 5 HDTVs we've reviewed

Aside from price, size is the number one criteria used by TV shoppers, so my Best 5 list consists of the highest-rated HDTVs in five size categories starting at 32-inches or less. If we review a new HDTV that gets a higher score, I'll update this list. Check out the other lists to the left for more choices.

Samsung LN-T3253H
Best HDTV 32-inches and under
Great style, oodles of features, and a solid picture combine to make the Samsung LN-T3253H one of the best LCD TVs available at its size.
Panasonic TH-42PZ700U
Best HDTV between 33- and 42-inches
For those who can spare no expense, the Panasonic TH-42PZ700U plasma offers the best picture quality in its size class.
Sony KDL-46XBR4
Best HDTV between 43- and 47-inches
Although not quite as impressive as the best plasmas, the 46-inch Sony KDL-46XBR4 outperforms any flat-panel LCD we've tested so far.
Pioneer PDP-5080HD
Best HDTV between 48- and 52-inches
The Pioneer PDP-5080HD produces the deepest shade of black--and thus one of the best pictures--we've ever tested.
Panasonic TH-58PZ700U
Best HDTV 52-inches and up
Although it costs more than any rear-projection big-screen, the 58-inch Panasonic TH-58PZ700U plasma offers superb image quality.

LCD TV vs. Plasma

This is the #1 question for me at any dinner party: Which is better, LCD TV or Plasma? This is a much debated topic and a fun one. When choosing between plasma and LCD TVs, you're actually selecting between two competing technologies, both of which achieve similar features (i.e., ,bright crystal-clear images, super color-filled pictures) and come in similar packages (i.e., 3.5 inch depth flat screen casing). To complicate the decision-making process further, price and size are two previous considerations that are rapidly becoming non-issues as LCD TVs are now being made in larger sizes and at competing prices with plasma.

Despite their similarities, the two technologies are very different in the way they deliver the image to the viewer.

Plasma technology consists hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each.

Whether spread across a flat-panel screen or placed in the heart of a projector, all LCD displays come from the same technological background. A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen (for flat-panel TVs) or one projecting through a small LCD chip (for projection TVs). LCD TVs reproduce colors through a process of subtraction: They block out particular color wavelengths from the spectrum of white light until they're left with just the right color. And, it's the intensity of light permitted to pass through this liquid-crystal matrix that enables LCD televisions to display images chock-full of colors-or gradations of them.
