TV Guide: The Differences between Plasma, LCD and LED Displays

May 4, 2015

 

With the continuous onset of new TV technology, it can be overwhelming to feel like you are choosing the right system – whether it be for your home, company or event.

All of TVs mentioned below offer High Definition television (HDTV) which provides a 1080p resolution.

PLASMA TV

 

A Plasma TV creates a picture from a plasma gas filled with millions of electrically charged atoms and electrons that collide when you turn the power on.

A Plasma TV is very thin and offers a viewing area from 42 to 103 inches.

Major Advantages: Plasma TV offers the maximum brightness, viewing angle and screen size as compared to LCD or LED options. 

LCD TV

 

A Liquid Crystal Display (LCD) television uses this technology to produce images. LCD televisions are thin, light, and are available in large sizes.

LCD TVs deliver a consistent, high quality picture in every situation – even in areas of sunlight and glare.

Because of its 120 and 240 Hz refresh rates, this TV offers a clear picture even for action oriented programming such as sports and movie options.

Major Advantages: LCD TV offers a great refresh rate and is very light and thin.

LED TV

 

A LED TV uses Light-Emitting Diodes (LED) to backlight the display. A LED is a semiconductor device that emits visible light when an electric current passes through it.

LEDs have significantly lower power requirements, convert power to light more efficiently and last much longer than most other lighting technologies.

LED TVs commonly come in two forms:

  • Edge-lit: In which the LEDs are formed around the rim of the screen using a special diffusion panel to spread the light evenly behind the screen. This allows for less localized dimming.
  • Back-lit: This is where the amps are behind the screen.

LED TVs also offer a consistent bright, clear and high definition picture.

Major Advantages: An LED TV offers the thinnest display and consumes the lowest amount of power compared to the other alternatives. It also requires no burn-in which means the TV will last longer. 

OTHER SELECTION CRITERIA

 

Here are some great questions to consider when choosing a TV:

  • How big is your room or viewing space?

    The last thing you want to do is overwhelm the viewer. A TV that is too big or conversely too small will not work. Make sure you have the right TV for the right space.
     
  • Will people be sitting or standing?

    If people will be standing (such as a few minutes in a trade show booth) or sitting (such as watching a 2-hour movie), quality of picture will make or break the viewing experience. For example, someone coming by the booth for 2-5 minutes would find a Plasma TV perfectly acceptable, but sitting down for two or more hours, may require a LCD or LED alternative.
     
  • Will people be in front of the screen or viewing it from an angle?

    LCD and LED TVs lose some of their picture quality when not viewed directly in front of the screen.
