By: Michael G. Worthington

LCD TV's vs plasma TV's which is better? If you're seeking a flat-screen, slim and sexy display, to watch high definition TV, you've a choice to use 2 technologies, LCD and plasma.


Over the years, the LCD vs plasma HDTV choice has been a fairly simple decision. If you desired a flat-screen that was about forty inches or bigger, you'd making a decision on plasma, otherwise you should choose LCD. However, as LCD technology improves, LCD HDTVs are getting bigger and more affordable, most of the major manufacturers expect the amount of LCDs they produce to grow steadily over the next several years while the quantity of plasmas will decrease. However, if you're looking for a high definition TV plasma's still has a lot to offer.

To appreciate the LCD vs plasma HDTV issue, we must view the way the two technologies work.


LCD HDTVs work by shining a light at the back of an LCD panel made up of a preset number of pixels. Each pixel is either red, blue or green and is turned on or off when a voltage is applied to it. When voltage is applied to a pixel, it is deactivated, which means light can't shine through it.

LCD TV's have an advantage that it doesn't require a "burn in" period as do plasma's. This is a characteristic of plasma TVs where they are accustomed to watch TV stations with logos permanently displayed on-screen or where they are employed for video games with games that have static images like a cockpit on flight simulators. The image literally burns-in the screen meaning that even when the image is not there you can still see a faint trace of it on the television. So for video game playing an LCD TV is a good choice

Plasma TV's

Plasma TV's have more than a million chambers which houses one or a combination of gasses. When a voltage is applied to the chambers the gas ionizes and displays ultra-violet light. This light strikes red, green or blue phosphurs coated inside of the chamber and a pixel displays this colored light.

Plasma HDTVs are more likely to have better contrast than LCDs because, even when a pixel on an LCD panel is switched off it does not block all the light coming through and so the pixel isn't completely black. Plasma High definition TV's also tend to have a wider viewing angle than LCDs, as on LCD Tv's the contrast and color of the image can change when a persons screen is viewed from different angles.

LCD vs Plasma HDTV conclusion

Technology is changing fast, but right at this time it's still true to say that at sizes of forty inches and above, plasma offers a less costly and generally better solution. For screen-sizes less than forty inches an lCD TV is a good choice as it would be hard to find plasma's in smaller sizes. However, as LCD and plasma technology improves and prices fall, this will change.
