How to Buy a New HDTV: LCD vs. LED vs. Plasma

July 15th, 2011


The first thing to remember about shopping for a TV is that everyone sees things differently. What may look crisp and perfect to one person could look grainy and washed out to another. In the end the best decision you can make is based on what looks good to you.

LCD vs. LED vs. Plasma


What kind of HDTV would be best for you?

LCD

LCD TVs are known for having poor black levels but recent developments have helped to fix some of the issues. LCD TVs are back-lit by cold-cathode fluorescent lights (CCFLs), so there will always be some light leaking through and you won’t get that deep black you see on a Plasma TV.
LCD also falls short of plasma when it comes to viewing angles as well, there is some color changes and wash out when watching an LCD from an angle. LCD TVs are best placed in rooms where there is plenty of seating directly in front of it. LCD image and color quality may also suffer when in a darkened room.
LCDs are available in a variety of sizes from 19″ to 65″, and in the popular 40 to 55″ size range, LCD and plasma are priced similarly.

LED

LED TVs are not necessarily new technology. They’re just an LCD TV that uses light-emitting diodes (LEDs) for back lighting instead of the standard cold-cathode fluorescent lights (CCFLs). There are two kinds of LED TVs: full array and edge-lit.
Full array means LEDs are placed across the back panel, just like in LCD TVs with a CCFL backlight.
Edge-lit came about as a way to make TVs even thinner. The lights are placed on all four sides and is projected to the center. Edge-lit LED TVs are the most common.
LED TVs are available in 32″ or larger, are often thinner and use a little bit less energy. Some models may offer slightly better picture quality, but are expensive.

Plasma

Plasma is the original flat-screen TV technology, and though newer LCD technology has begun to edge it out you still tend to get a better picture quality from plasma. Plasma has wider viewing angles, allowing for more people to watch from a wider space.
Plasmas main issues are that they’re larger, heavier and less energy efficient than their LCD counterparts. They also have issues with reflecting light off their glass screens, which can make viewing in a bright room difficult. Plasma screen do have superior color richness, but are best viewed in darker rooms.
Plasma TVs are available in 42″ or larger and often beat out the LCD competition in price, especially 50″ and above. 50″ is considered by most to be the perfect size for a plasma TV.
