Learn all you need to know about OLED TVs

OLED stands for Organic Light-Emitting Diode. While the terminology might not be paramount for an end-user, several aspects of this technology are. If you have been having trouble understanding just what an OLED TV is and how it differs from LED and Plasma TVs that now exist on the market, you’ve come to the right place. Everything you need to know can be found in the paragraphs below.

The basics of OLED

OLED TVs have been on the market ever since 2013, but the high prices have prevented most of the buyers from going out and getting one. Since the technology was relatively new, it didn’t seem feasible to most consumers to waste that much money on a TV they knew nothing about.

In 2015, several companies such as LG started to launch new models at affordable costs. OLED is regarded as one of the highest advancements in the industry, as it uses less electricity and is thus more eco-friendly compared to its counterparts. On this account and others, these products are more efficient and are considerably thinner and lighter than other smart TVs.



The difference between LED and OLED

The core difference between the two is the way they use energy. OLED relies on a carbon film that’s placed before the glass screen. That makes it possible for the unit to emit its own light. By contrast, LCD displays need an independent light source, in order for them to provide brightness.

For a very long time, it was close to impossible for OLED TVs to work, as most of the prototypes had issues with longevity. Thanks to innovations brought by LG and Samsung, we’re now able to buy these units at a somewhat affordable price and use them efficiently and for many more years.



Why OLED TVs are becoming more popular every day

The advantages of OLED over plasma and LED are many. To name just a few, OLED sets are thinner and easier to maneuver, on account of being lighter. As previously pointed out, they don’t have a backlight. Since the light they emit is direct, the picture quality is superior to the one of LED. The contrast, color, and viewing andles are all better.

Also, the pixels of OLED sets can be turned off one by one, allowing the unit to offer an infinite contrast ratio. Furthermore, OLED TVs have one of the lowest response times of TVs on the market today, which significantly contributes to eliminating motion blur.

OLED technology can virtually be split up into two categories: passive-matrix (PMOLED) and active-matrix (AMOLED). Back in the day, when a person was interested in purchasing an LCD screen, he or she was able to choose between a TFT LCD or an active-matrix LCD. This distinction is rarely emphasized by the manufacturers nowadays, as most of the products in the line are active-matrix.

The same goes for AMOLED and PMOLED. Although both technologies exist, active-matrix is far better than its counterpart, because it is able to provide superior motion. In theory, every pixel in AMOLED can be addressed individually.




Moreover, OLEDs can be categorized depending on the sub-pixel structure. Some companies find that using the same RGB pixel structure frequently employed in plasma TVs work with OLEDs, while other brands utilize WRGB. WRGB consists of an extra white sub-pixel, aside from red, green, and blue. According to the manufacturing brands producing these models, adding a white sub-pixel provides brighter images.



Several OLED TV problems

For the time being, OLED is still being seen as a premium TV alternative. When the first models were launched, their base prices were close to ten thousand dollars, but considerable improvements have been made in this sense. Thanks to advancements in the development technology, companies like LG and Samsung have managed to lower the prices so that nowadays a consumer can buy a unit with as little as three or even two thousand dollars.

The main issue with OLED was that, in the past, the cost of production was very high. Building top-quality models was a matter of trial and error, and many of the ones initially developed ended up in the dumpster.

Another issue of OLED’s is the blue pixel. Compared to its red and green counterparts, the blue pixel deteriorates twice as fast. The death of the blue pixel can lead to a shorter lifespan of the unit and a change in the color balance. However, progress is being in made on this account, and it’s no doubt that the issue will be resolved in the future.
