Difference Between Plasma and Projection TVs

Television has been a major source of entertainment for everybody for decades. There are so many other sources of entertainment that came after that, but TV remained constant.

There is so much evolution in technology that affected the designs, the features, and their advantages. 

Television now comes in different shapes and sizes and with various features. Such two types of Television are Plasma TV and Projection TV. They both are very different in features, resolution and the techniques used made them very distinct from each other.

Plasma vs Projection TVs

The main difference between Plasma and Projection TV is that they have different techniques of displaying the images. Plasma TV uses Plasma gas to light phosphorus which is used to further display the images. Projection TVs are bulky and have much larger screens. They use a simple beam of lights to display the images.

Plasma vs Projection TVs

Plasma TVs are in trend nowadays because of their thinner display and their high-quality image resolution. They use noble gases instead of the heavy picture tube and thus the phosphorous get lightened up to display images.

They are designed to produce high-definition and standard TV signals. They are considered to be luxury because of the flat and wider display.

Projection TVs are having very larger screens and have four types of Projection techniques. These techniques are Cathode rays Tube, Liquid Crystal Display, Digital Light Processing, and Liquid Crystal over Silicon.

They initially create small images and then project them onto the screen using light to enlarge the images.

Comparison Table Between Plasma and Projection TVs

Parameters of ComparisonPlasma Projection TVs
SizePlasma TVs are thinner and wider as they contain thin materials and are ideal for today’s trend. They are of two types, one comes in very big and bulky size, while the other is thin and can be mounted on the wall.
ScreenThey are of large size but less in comparison to the projection TVs.They are not space-consuming.They are of very large size because they are projected to the contended size. They are very space-consuming.
DisplayThey provide better and higher-quality images as compared to that of CRTs.They have good image quality but less than that of Plasmas.
Techniques usedThe technique used to display images is the use of hot plasma gas to lighten up the phosphorous and display the images.Projection TVs only use beams of light to display the desired images.
PricePlasma TVs, because of their high-quality image production, are much more expensive.Projection TVs have a larger screen but are still less expensive because of the quality of images.

What is Plasma?

 A flat panel television uses similar technology as that of CRT. Images in the Plasma TVs are displayed using the lighting of phosphorus and in this case, this phosphorus is lighted by the hot gas called Plasma.

They are not space-consuming and expensive than Projection TVs.

They are very thinner and wider as they contain very thin material and now they are setting thin TV trends. They use colored pixels from fluorescent bulbs to form an image where each pixel is lit up individually.

The pixels contain subpixels of different colored phosphorus (Red, Blue, and Green) which further combines and forms the image.

What is Projection TV?

As its name, Projection TVs have larger screens just like Projectors and uses the same techniques. They first produce a display image small and then using a beam of light they display that picture having a much larger size.

There are two types of Projection TVs that are available and have different ways of displaying the images.

First is front-projection display systems, the projectors are used apart from the screen. The picture is then picked up by the lights and gets projected to the screen then.

The projector is used for reflecting the images in front of the screen. Another is Rear projection, the images are projected at the back of the screen rather than in the front.

Main Differences Between Plasma and Projection TVs

  1. Plasma TVs usually uses a gas called Plasma to light up the phosphorus that is responsible for displaying images whereas Projection TVs simply display images on the screen using beams of light.
  2. Plasma TVs have a screen that are pretty wider and thinner but Projection TVs can display images and projected to the contended size and has much larger screens.
  3. The size of Plasma TVs are small, thinner and can be hunged on the wall whereas Projection TVs are bigger, space-consuming, need dar room and flat wall for projection.
  4. Plasma TVs are costly in price than projection TVs because of the high quality of images they producing and the less space-consuming reasons whereas Projection TVs are less price as they are very space-consuming.
  5. The display of images by the Plasma TVs are of high quality because of the technique used whereas Projection TVs has image quality less than that of Plasmas.


Both these above Television are a lot different from each other. They have different techniques for displaying images and screen resolution.

When buying a TV, you should keep some factors in mind to make better choices.

Factors such as the size of the room, availability of a proper ambiance, compatibility, size of the screen, high definition set up, some normal specifications such as contrast ratio, frame rate, etc.

For example, Plasma TV can be hanged on a wall, and have good resolution along with a small screen size which is a great choice if you have small space for setting up.

When talking about the projection TV, one needs to have a larger room. Though it comes at an affordable rate in comparison to the Plasma TVs that are expensive, one has to make compromises in resolutions when it comes to Projection TV.
