Why did plasma TVs disappear from the market?
Plasma TVs were once all the rage, but despite the good picture quality they provided back then, they are no longer. plasma TVs are not available in the market. Why were plasma televisions suddenly left out of the field of technology? In this note, while examining this issue and the reason for the disappearance of this model of televisions, we will help you to find out what other product you can buy instead of this type of television if you are planning to buy a plasma television.
How does a plasma TV work?
Before we talk about why manufacturers have not been interested in producing plasma TVs for several years, let's first talk about the working mechanism of plasma TVs.

Plasma products emit gases that emit light when charged with electricity to display images. Most of these lights are classified as ultraviolet lights, which are invisible by default. However, when these lights hit the phosphor cells, they are converted into visible light and the images projected on the display panel are created in this way. Each pixel in a plasma TV contains three phosphor cells; Red, green and blue. These primary colors try to combine with each other to create the specific colors that need to be played on the TV. Therefore, plasma products emit certain lights by themselves and do not need a backlight. This allowed plasma products to have a "contrast ratio" advantage, and these TVs could turn off some pixels when black was needed. The quality of images in this type of television was extremely excellent at that time.
On the other hand, plasma televisions offered a very fast response time, a very high refresh rate, and a very impressive viewing angle. All these features made plasma products have a very high purchase value for customers.
Where was the problem?
Although plasma products have some positive points, this type of TV is far from a perfect product. For example, the screens of this type of TV are not so bright, and for this reason, this type of TV is more suitable for dark spaces. The best plasma TVs offer at best 100 nits of brightness in a 10% window test. By comparison, ultra-modern LED-backlit TVs can be as bright as 1,000 nits.
Plasma products were also prone to temporary and permanent image retention or burn-in. However, at least this problem became less due to the evolution of plasma technology. Another problem with plasma products was electricity consumption and heat production on the other hand. These TVs required a lot of electricity to work and also many internal fans had to be installed in these TVs to keep the device cool. The last drawback of this type of products was in this issue. Although plasma products were lighter and thinner than CRT TVs, these TVs were still considered heavy and thick.
Despite the negative points in plasma products, there are still buyers. were found to prepare plasma products; Because these types of TVs have similar disadvantages compared to LCD TVs with backlight, for example, high power consumption and the thickness of the TV panel.
Everything changed with the advent of LED backlighting. LCD TVs with LED backlight later became known as LED TVs. LED TVs are thinner in terms of screen dimensions and consume less electricity. Of course, the early examples of LED TVs were weaker in terms of image quality and screen angles compared to plasma products, but it must be admitted that the disadvantages of plasma TVs compared to other advantages did not make the customer interested in buying plasma TVs. p> The last blow to the coffin of plasma products was the emergence of OLED and 4K televisions in the market.
The last blow to the coffin of plasma products was the emergence of OLED and 4K televisions in the market. plasma TV manufacturers realized that manufacturing 4K plasma TVs requires a lot of time and capital, and it was not really an economical investment for the manufacturers. On the other hand, OLED TVs offer most of the advantages available in plasma products to the customer without any other problems.
It was in 2014 that manufacturers and prominent TV production companies officially abandoned the production of plasma products and only focused on They focused on making LED and OLED TVs; Two types of attractive and exciting technology that still managed to get a positive opinion from the audience after all these years.
The best alternatives to plasma TVs
OLED TVs In a way, they are considered the spiritual successor of plasma products and have very important advantages. For example, OLED TVs have self-emitting pixels similar to plasma products. Therefore, these products can have a contrast ratio close to infinity; Something that was not possible at all on plasma products. While plasma products can produce deep blacks by turning off certain pixels, there is always some charge in the plasma that causes some remaining pixels to glow. As a result, a plasma TV cannot produce perfect blacks.
OLED TVs, similar to plasma products, offer excellent viewing angles and fast response times. Also, OLED products have far more brightness and thinner screen dimensions.
Unfortunately, the phenomenon of burning in OLED TVs is also considered an important negative point. However, due to significant advancements in OLED technology and various protective devices in TVs, burn-in is no longer a huge problem for TV buyers. OLED TVs are the best future options to buy and are far better than plasma products. Having said that, OLED TVs are more expensive than LED TVs. For this reason, if you have a limited budget, you can buy an LCD TV instead of an OLED or LED product. Unlike LCD TVs at the time of plasma products, modern LCD TVs offer a better contrast ratio due to the Mini-LED backlight and Full-array local dimming technology and have a fast response time.
