TV Types Explained | Plasma, LCD, LED & OLED

A little over fifteen years ago, new types of TVs began to appear. Until that time, people used display devices built on the same principle. The characteristics of new products are getting higher, the quality – better. Consider a quick overview – a variety of the main, most common types of TVs showing the strengths and weaknesses.



Televisions with an electronic beam tube, or, as they are commonly called, “kinescopic” (although it is not the only type of television equipped with a kinescope), have long been considered standard and were widespread. Although they are reliable, they cannot be compared in quality with displays based on advanced technologies. Every year the production of CRT TVs decreases.


This item would have been extended some time ago, as there were no decent alternatives to mesoscopic televisions. Now we can highlight only one significant advantage – low cost. Otherwise, TVs with an electronic beam tube lose out to more modern designs.


One of the main drawbacks of CRT screens is their size and weight. Even devices with a small diagonal screen can weigh 5-10 kilograms and take up a lot of space.

Other drawbacks include:

  • High energy consumption
  • The image quality is not clear enough.
  • Fire hazard due to the use of ultra-high voltages and heated electrical elements;
  • the electron beam tube is a source of adverse radiation and magnetic fields for human health.

Projection TVs

The desire to increase the diagonal of the screen of kinescopic TV devices led to projection TVs. In them, the image, with the help of optical systems, increased to the necessary size.

At one time, this kind of TV was popular as home movies.


  • The large screen size
  • reduced energy consumption compared to CRT models.


To the disadvantages typical of all TVs with kinescopes, the projection has a few additional drawbacks:

  • Huge size and weight;
  • Narrow viewing angle
  • expensive maintenance.


Liquid crystal (LCD) TVs

Years of research, development, and improvement of the most complex technology of liquid crystals have led to a real revolution in the production of televisions. There were stylish flat panels on the market, which began to differ from their predecessors both externally and many times surpass them in all respects. The no longer necessary use of bulky endoscopes allowed to produce various forms and designs – for all tastes.

The novelty quickly gained universal popularity.


  • High-quality clear image
  • Small weight;
  • Increased sweep frequency – no flickering;
  • Acceptable viewing angle
  • no electromagnetic radiation.


  • Poor black saturation creates glare when viewed in brightly lit rooms;
  • a large response time can be blurring.



In fact, these are the same liquid crystal panels, which have the same characteristics and have only a few differences. They are due to the design features – the screen lighting is made not with the help of lamps but with the use of led LED-matrix.

  1. The main difference is the best saturation of the black color, which makes the image look more attractive.
  2. LED lighting is more reliable. If it breaks, it is easier to replace than lamps.
  3. Electricity consumption is almost one and a half times lower than the standard LCD TVs of the same size.

Today, this type of TV is the most common in the world.


Plasma panels

At its core, a plasma panel is a huge number of microscopic transparent capsules filled with special gases, having a unique property – to glow at the electrical discharge. Each pixel of such a screen contains three capsules of different colors: red, green, and blue. Depending on which gas cell the TV controller will apply voltage to, it will glow in this color.


Devices with plasma panels are the most modern. They have a clear contrasting image, a vast viewing angle, and high durability. They are equipped with a widescreen, which allows you to view the movies with the highest resolution.


Cons of “plasma” a little, which are not significant for the average consumer. Thus, they consume more energy compared to LCD analogs. But in a modern house full of diverse techniques, it remains almost imperceptible.

Another significant drawback is the high cost, so not everyone can afford to buy this type of TV. The presence of additional features (built-in Android set-top box, 3D) makes them even more expensive.

Progress on the development of better types of TVs does not stop to this day. There are already new generations of laser projection technologies that will soon change the perception of TV devices.
