Difference between Plasma and LED TV

Updated on February 20, 2018

The latest technology in the manufacture of television sets have given rise to plasma and LED TVs that produce stunning picture and sound quality – and they keep improving each passing year. As a customer looking for a TV to buy, the many different features that come with each can confuse you since each type has different advantages that suit different needs. To help you decide which one to go for, here is a closer look at the differences between each of them.


Plasma TV

A Plasma TV uses an arrangement of tiny gas cells that are sandwiched between layers of two glass sheets. These gas cells act like small fluorescent lamps by producing ultraviolet light which lands on blue, green and red points on the screen. These points then glow to form the pictures.

An LED TV is simply an LCD TV that uses a backlight system comprising light emitting diodes instead of fluorescent lamps that are used in standard LCD TVs. These TVs are energy efficient and usually produce better contrast and improved accuracy in displayed colors than the LCD ones that use fluorescent lamps.

Plasma TV vs LED TV

What is the difference between plasma and LED TV? The difference is in their energy consumption that results from their different sources of light used to produce images.

An LED TV works using liquid crystal cells that regulate the amount of light passing through them to form an image. These liquid crystals get their light from an arrangement of light-emitting diodes placed either along the edges of the back of the screen or along the entire back of the screen.

A plasma TV, however, does not need a back lighting system. It uses phosphors that light up themselves to create images on the TV screen. This however, does not mean that the plasma TVs are more efficient in power usage than LED TVs. A plasma TV is slightly heavier and more expensive to run in terms of energy consumption. It consumes more power than LED TVs. LED TVs use very minimal energy because they are made of diodes which are very efficient in power consumption.

Of the two, plasma TVs were the first to hit the market before being replaced by LED TVs. Initially plasma TVs boasted of rich picture quality unmatched by any other type of TV, but the latest technology in the manufacture of LED TVs have pushed performance, costs and power consumption dynamics so much that plasma TVs are no longer being produced as before.
