Plasma vs LCD – again

Which is good?

Plasma will give a better black, since it can off its pixel totally which will make it as black.   LCD on the other hand use filter to change color and thus will only give shades of gray and not true black.  However, with today’s technology, LCD’s “black” is not as obvious to the naked eyes.

LCD will give a sharper image.  Thus when you walk into a room with both plasma and LCD of the same size, you will first be attracted to the LCD panel as it look nicer.  But after staying in the room for sometime, you will feel that the plasma panel is nicer to watch.

Plasma has a burn-in effect, meaning if you watch a channel with a channel logo on the top right corner and watch only that channel.  After sometimes the color at that top right corner will be similar to the logo even when you watch other channel without any logo.  There will be a dim logo as if it has been printed on the screen.  But this is very rare.  LCD doesn’t suffer from this effect.

Plasma has a life span of 30,000 hours, but if you do the maths, watching TV 10 hours a day, 7 days a week, your plasma will still last you 8 years.  And if you drop it down to 5 hours a day, which is more of a norm, then it will last you 16 years.  LCD on the other hand doesn’t neccessary has a standard life span, but the light bulb will burn out after sometimes and it can be changed.  But the cost of changing the light bulb is normally quite expensive.

Plasma is cheaper now as compared with the price of an LCD of the same size.  This is because plasma as a technology is more mature than LCD, at least in terms of bigger screen TV panel.

Both are good technology, so in the end it is just your budget and your eyes that will decide which panel you will ultimately go for.  Just remember don’t let the sales person decide for you, you are the one using it and not him/her.
