CRT TVs Are A Terrible Idea. Here’s Why


The first TVs used for entertainment, the CRTs saw a huge decrease in sales when the newer, slimmer, and better LCD TVs went mainstream. Now in 2015, almost every household has one of LCD, Plasma, or LED TVs. But yet, as many countries like India are still in their developing period, some people still prefer the much cheaper and almost obsolete CRTs over their relatively expensive modern counterparts. But actually, buying a CRT, even if one is on a tight budget, is not a smart move in any way. Here’s why.

CRT TVs have a Size Issue

CRT TVs are huge

The first and most obvious disadvantage of a CRT TV over other forms of TVs is the size and weight. A CRT consists of a vacuum tube through which electrons are to travel, hence the size of the TV is large and the TV as a whole is quite bulky.

Meanwhile, other TVs which are based off LED or LCD are extremely thin and don’t weigh as much as the bicep wrenching CRTs do.

CRT TVs Impact human health and environment

A CRT Television consists of a vacuum tube and an electron gun that emits electrons when heated and focused in a beam. These electrons are deflected using a magnetic field to bombard a phosphorous coating on the front of the display, which glows and hence forms the desired images on the screen.

CRT TVs hate the environment

Simple, isn’t it? Not quite.

While all of the above stuff happens inside the TV, electromagnetic fields are generated in the process. Exposure to these fields is very hazardous in the long run, as these fields affect the functioning of living cells and these Very Low Frequency Emissions (the fields) possibly cause chromosomal changes, disturbance in the growth of bones, irregularities in the heart rate and even alterations to the genetic structure!

To avoid all this havoc, one needs to sit at least 85cm away from the CRTs because these fields are radiations, thus they obey the inverse square law and weaken over the increase in distance.

We’re safe if we sit far away from them then?

Nope. What about AFTER you have finished using the TV and want to dispose off it? CRT TVs contain high amounts of leaded glass- a toxic compound, which can be released upon breaking of the screen, causing great hazards to the environment. Also, these barium compounds are dangerous to humans as well as they are water soluble and if consumed in large amounts, can cause cardiac irregularities, damages to the nervous system, anxiety or even paralysis.

CRT TVs are Power Hogs

CRT TVs are also power hogs

CRT TVs are the least power efficient of form of the television. They consume large amounts of electricity while starting and heating up the electron guns. Other forms of TVs like LEDs, on the other hand, use a backlighting to display the images, hence are extremely power efficient as the only equipments running on power are the speakers, the dim display panel and some white light bulbs (LED or fluorescent) for the backlighting.

So be careful while buying a television next time and try to avoid CRTs at all costs. They may be extremely cheap, but trust us; they are not worth a penny of your money. Instead, go for a 4K TV if you have the budget.
