Plasma vs LCD, which is right for me? The two different camps of flat panel display standard will, of course, gladly spruik the advantages of their own standard and the deficiencies of the other. But which type of display, plasma or LCD, is better? And which will give you more bang for your buck? 1. Plasma and LCD - what's the difference? | 2. Picture quality | 3.

Plasma and LCD panels may look similar, but the flat screen and thin profile is where the similarities end. Plasma screens, as its name suggests, uses a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens (liquid crystal display) are in layman's terms sandwiches made up of liquid crystal pushed in the space between two glass plates. Images are created by varying the amount electrical charge applied to the crystals. Each technology has its strengths and weaknesses, as you'll read below. 2. Is there a difference in picture quality between plasma and LCD screens and normal CRT TVs? It's not what's happening behind the screen that's important - it's how the screen performs as a television that matters the most. In that regard, both plasma and LCD sets produce excellent pictures, although many home entertainment specialists and gamers still say CRTs produce the best overall images (although the latest plasmas are particularly good, and LCD sets are quickly catching up in terms of quality). Those same home entertainment specialists will tell you that for basic home theatre-like usage, plasma screens have a slight edge over LCDs. This is because plasma screens can display blacks more accurately than LCDs can, which means better contrast and detail in dark-coloured television or movie scenes. The nature of LCD technology, where a backlight shines through the LCD layer, means it's hard for it to achieve true blacks because there's always some light leakage from between pixels. This is steadily improving with every new generation of LCD, however. 3. What advantages does plasma have over LCD? Apart from better contrast due to its ability to show deeper blacks, plasma screens typically have better viewing angles than LCD. Viewing angles are how far you can sit on either side of a screen before the picture's quality is affected. You tend to see some brightness and colour shift when you're on too far of an angle with LCDs, while a plasma's picture remains fairly solid. This is steadily changing, however, with more and more LCDs entering the market with viewing angles equal to or greater than some plasmas. Plasmas can also produce a brighter colour, once again due to light leakage on an LCD affecting its colour saturation. Plasma pundits will also tell you that some LCD screens have a tendency to blur images, particularly during fast moving scenes in movies or in sports. While that was true for older generation LCD screens, newer models have improved significantly -- so much so that the differences in performance between LCDs and plasmas in this regard is almost negligible (here's a tip -- if you're shopping for LCDs, check the pixel response time, measured in ms. The lower it is, the better the image quality in fast moving scenes). Traditionally, the biggest advantage plasmas have had over their LCD cousins is price, particularly in the large screen end of the market. In the past 12 months, this has changed, with LCDs matching or even beating plasmas in both resolution and price. Plasmas being sold generally run between 42-inches and 63-inches wide, with the cheapest standard definition 42-inch . LCDs, on the other hand, generally top out around the 52-inch mark -- though there is now a ludicrously expensive 70-inch available -- but are incredibly competitive with similar-sized plasmas. In the six months since we last updated this feature, prices of the replacements of two flagship TVs have dropped by a third. 4. What advantages does LCD have over
