OLED, LED, LCD, Plasma, HDTV – What’s the Difference?

Lcd Hdtv DigitalI will try to explain each television type, but the choice to purchase a new TV should include careful research, and best quality for the price. But what do all these letters of TV models mean?

OLED - An organic light emitting diode (OLED), also light emitting polymer (LEP) and organic electroluminescent (OEL), is a light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. (source wikipedia)

LED - Means "Light Emitting Diode" television.  LED TVs are actually LED back-lit LCD TVs.

LCD - Stands for "Liquid Crystal Display" they use this technology to display color television images.

Plasma -  Images are produced by xenon and neon gas contained in hundreds of thousands of tiny cells positioned between two plates of glass. And is made up of a series of pixels, with every pixel made up of a series of 3 sub-pixels.

HDTV - "High Definition TeleVision" means more than the usual number of lines per frame so its pictures show more detail

OK, are you really confused yet? Imagine you walk into a consumer electronics store for a LED TV, the salesman shows you a LED set. You are impressed, but truth be told it is really a LCD TV, with LED back-lights. The only true LED TVs are the ones you see in major sporting arenas.  Plasma TVs were always built with great contrast levels, but LED TVs are catching up with them in this department.  The newer LED TVs are touted as 40% more energy efficient.  Main point is what manufacturer's refer to as LED TVs are actually LED back-lit LCD TVs and work COMPLETELY different than OLED TVs.

Here are some advantages of LED TVs

1. Gives deeper dark & black images than regular LCD's
2. Consumes alot less power than regular TVs
3. Lighter colors are brighter because the LED back-lights are brighter when turned on
4. Can have a wider range of colors if LED back-lights are made up of red, blue, and green

With a life span of 50,000 hours or more LED back-lighting is the most durable lighting system in the television industry at present and with benefits such as not suffering from a initial 'warm up' time, 178 degree viewing angle's and ultra high contrast ratio's, LED TVs are currently the highest spec LCD televisions available on the market today.  The newer LCD TVs and the NEW LED TVs are nearly 10 times more efficient than the Plasma TVs.


Plasma TVs are very popular flat HDTVs, but they require more than just low prices to stay competitive with their counterparts.  Plasma is great in term of picture quality and smoother motion with 600Hz (LCD & LED have maximum 240Hz).  Plasma is not a dead technology and in fact has been perfected in the past few years.  Plasma also has a wider viewing angle, and  a superior contrast ratio.  Plasma TVs produce great sharpness as a result of being able to present deep blacks.  LED TV vs plasma TV is an issue that has divided the opinion of experts and consumers the world over today.  Plasma is cheaper than LED as people are still going for the LED because of the old wrap about plasmas.  The clear difference in picture quality between LCD and plasma is the superior black level of plasma.  Each pixel on plasma generates its own color and illumination, which LCD lacked.


HDTV allows you to receive high definition terrestrial broadcast content via the built-in tuner.  HDTV is broadcast in Dolby Digital format.  Understanding some of the basics of HDTVs will helps you determine the differences between the options and which works best for you.  You may come up with all sorts of questions before buying your first HDTV.  All modern TVs are now HDTV, whether the insides are LCD, DLP, or Plasma.  What's more, with other slim HDTVs that save space by placing all the workings in a separate box, Samsung have managed to fit the tuner, and all other electronics into the units tiny frame, and have added some great energy saving features as well. There are just a few main types of HDTVs: LCD, Plasma, Projection and the newest, LED.  Another common term is flat panel; this included LCD, LED and Plasma TVs because of their very thing profile.

Technologies are Getting Better

The new LED technologies greatly improve the visual impact of an LCD.  Over the last few years, top manufacturers of plasma TV's have also been creating some technologies to combat this, but so far LED TVs have the advantage.  That is why there are different technologies.  There's still always a compromise when choosing between technologies.  They buy it because there are technologies that keep pushing the limit further.  For Plasma technologies have increased anti burn in tactics as well as computer and static signal handling.  Along with superb images handling at high speeds, these new models seem to be moving away from the old Dynamic Contrast Ratio seen in old LCD TVs to new technologies.

Rest assured, when the time comes to make a decision to purchase any of the above types of TVs, and as soon as you have it all connected to your peripherals systems. Lo and behold a newer, sleeker, higher resolution, better picture, makes the popcorn model will hit the market. In closing, I'll quote an old line from the Honeymooners (if under 40 disregard), I'll tell you why, Alice - I'm waiting for 3D Television!
