Plasma TVs vs LCD TVs
LCD vs plasma HDTV 's this is best? If you're seeking a flat-screen, slim and sexy display, to view HDTV, you have a choice of two technologies, LCD and gas plasma. Each has benefits and disadvantages and so each is more appropriate in specific circumstances. Historically, the LCD vs plasma HDTV choice has been fairly simple. If you desired a flat-screen that was about 40 inches or bigger, you'd to pick out plasma, otherwise you should choose LCD. However, as LCD technology improves, LCD HDTVs are obtaining bigger and the majority of the major manufacturers expect the amount of LCDs they produce to grow steadily over the next few years while the number of plasmas will decrease. However, if you're looking for a flatscreen TV today, plasma still has a lot to offer. To understand the LCD vs plasma HDTV question, we have to consider the direction the two technologies work. LCD LCD HDTVs work by shining a light behind an LCD panel comprised of a fixed number of pixels. Each pixel is either red, blue or green and is switched on or off when a voltage is applied to it. When voltage is applied to a pixel, it is deactivated, meaning that light can't shine through it. The main advantage of LCD vs plasma HDTV is that LCD panels don't suffer from what's called burn-in. This is a feature of plasma TVs where they are accustomed to watch TV stations with logos permanently displayed on-screen or where they are employed for video gaming with games that have static images like a cockpit on flight simulators. The image literally burns-in' the screen meaning that irrespective of whether the image isn't present you are still able to see a faint trace of it on screen. So for video gamers particularly, LCD is an improved choice than plasma. Plasma Plasma HDTVs have over a million chambers which house one or a combination of gasses. When a voltage is applied to one of these chambers the gas ionizes and emits ultra-violet light. This light strikes red, green or blue phophors coated internally of the chamber and a pixel emits this color light. Plasma HDTVs tend to have better contrast than LCDs because, whether a pixel on an LCD panel is deactivated it doesn't block all the light coming through and so the pixel isn't completely black. Plasma HDTVs also tend to have a wider viewing angle than LCDs, as on LCD HDTVs the contrast and color of the image will be able to make when screen is viewed from different angles. LCD vs Plasma HDTV conclusion Technology is changing rapidly, but right at this moment (July 2004) it's still true to say that at sizes of 40 inch and above, plasma offers a less-expensive and generally better solution. For screen-sizes less than 40 inch LCD is better. However, as LCD technology improves and prices fall, this will change. A HDTV will raise the level of your home entertainment system to a new level.
