different kinds of tvsThankfully, Cathode Ray Tube (CRT) TVs are no longer our only option. Moreover, you can’t find those dinosaurs on the store shelves anymore, because they have been replaced by slick modern flat screen models. No doubt this is great news, but now we have all these new HDTV technologies to choose from – things got complicated!


Down to Earth Communications is here to show you the key differences between the leading TV technologies on today’s market. Let’s start with the inner workings.


Liquid Crystal Display (LCD) technology employs liquid crystals that are illuminated by lamps (namely Cold Cathode Florescent Lamps), and as the white light passes through, the image is created.

Plasma TVs

Plasma technology is very intricate and involves gases (neon and xenon) that get excited by electrical current which causes them to emit UV light, The UV light strikes red, green and blue phosphors also located in the screen making them produce visible light.


Light Emitting Diode (LED) technology basically improves on LCD technology by introducing a new light source: light emitting diodes instead of lamps.

So we have these 3 different technologies competing for your attention and spot in your house. As a Maryland TV installation professional, we can tell you for sure there’s no difference between these TVs when it comes to installation. However, there are major differences in user experience and other areas:

Contrast ratio and Brightness

Plasma will give you the best contrast ratio; however, plasma TV might be more suitable for darker rooms, because it doesn’t stand out in bright light as much as LED and LCD. Plus, Plasma is known for its supreme rendering of black colors, which is perfect for watching in the darkness or with deemed lights.

Energy consumption

Due to its reliance on electricity for illuminating every screen pixel individually, plasma TVs consume more power. LED and LCD panels would be a better choice if energy efficiency is an important factor for you. But plasma technology keeps evolving, and it won’t take long for it to catch up to the competitors in this department.

Viewing angle

Plasma TV is a winner in this category because it allows for great picture quality and color rendering regardless of the viewing angle. So when you have a lot of people watching TV from different spots, everyone can enjoy the beautiful picture. LCD has the narrowest viewing angle of the three.

Color and detail

When it comes to the colors, LED and plasma TVs are in the lead, but not by far. All modern TVs are well capable of producing life-like images, and if you are not an expert, it’s very difficult to spot the difference. However, when it comes to detail and motion flow, nothing can beat plasma just yet. So if you like watching sports and playing video games, plasma TV will provide the most enjoyable experience with minimal motion blur.


LCD technology is the oldest of the three and has proven quite durable. Because LED TVs populated the market only a couple years ago, their lifespan hasn’t been determined yet. As for the plasma TVs, they seem to die faster than their counterparts, but manufacturers keep working on extending their lifespan.

As you can see, there’s no single winning TV technology that everyone should buy. If you are really picky about the picture quality, can notice the slightest imperfections, and enjoy watching sports, then plasma TV is the way to go. However, if you are concerned about lifespan and energy consumption, and don’t care much about tiny flaws, then LED or LCD would be a better choice. Be sure to research different brands and read consumer reviews before making a purchase.
