The television is still a common household appliance in most homes. Although more and more digital platforms such as YouTube or Twitch gain ground to traditional media, having a TV in the living room or bedroom to enjoy is always a good option.
Seven things to look for when choosing a TV
And although the market for televisions, for the most part, are the well-known LED screens; since a time ago OLED panels are on everyone’s lips. Its high price (more than 1,000 euros) makes taking the “jump” can be seen as risky.
The main feature of OLED screens, acronym for organic light-emitting diode (organic light emitting diode), do not require an external light source. In other words, the “organic” components of the screen emit light when the electric current passes without the need for other light sources.
But how does it improve the experience? We summarize you some of the advantages and disadvantages, of these screens and some other tips to avoid making mistakes in your purchase.
Five advantages of OLED TVs
OLED panels, common from brands such as LG or Philips, can look very attractive for people who want to completely renovate the television in the living room (or bedroom). So what advantages does it have?
1. Lower consumption.
One of the main incentives to look at an OLED TV is that the electricity consumption is much lower. As we have mentioned before, the television diodes do not need an extra light source, since they generate light on their own. In addition, this also makes them able to turn off the pixels individually, which also saves energy.
2. “Pure black”.
The backlighting of OLEDs allows each pixel to be turned off and, therefore, the blacks are much darker and more intense. In an LED panel, for example, this cannot be achieved as the pixels cannot be turned off. In addition, OLED TVs have an RGBW matrix, which shows a white more similar to that seen by the human eye.
3. Fine TVs.
By not requiring more illumination than the diodes themselves, OLED TVs are noticeably thinner than their competition.
4. Curved screens.
OLED technology also has a flexible structure, which allows the screens to be curved. Although this is not universal in all models, it is something to keep in mind.
5. Viewing angle and ghosting.
OLED televisions do not lose quality according to our position, compared to LED panels, where if we place ourselves diagonally, fidelity in colors and brightness can be lost. This is very important if, for example, we place the television in the living room, where there may be more than one location from which to watch it.
In addition, the response time has been improved – it is a measure, in milliseconds (ms), that indicates the time it takes for a pixel to go from black to white and vice versa – has dropped to 0.002ms (compared to 2ms from the LEDs). This ensures that the image does not appear blurry or trails are shown when, for example, playing video games.
Five disadvantages of OLED panels
All of the above seems to indicate that OLED televisions are practically unbeatable … but they also have their drawbacks.
1. Very high price.
The manufacturing costs and the fact that it is a technology that has not yet become popular (the first television with OLED panels is from 2014) make the cost very high. In Spain, this type of television does not usually go below 1,000 euros.
2. It is very big.
Either because of the technology or the price, OLED televisions are not less than 55 inches (a diagonal of 1.40 meters). If you have a very specific and tight space to occupy with a television, OLEDs are likely to be somewhat large for your home.
3. Screen more fragile.
That the television is so thin and the panel so delicate converge in a television more fragile than an LED to blows. This should be taken into account if you want to put it in an area where minors can play or it could suffer an accidental fall, since it will probably break.
4. Much lower brightness.
Compared to other technologies, such as Samsung’s QLED televisions, OLEDs seem to lack brightness. For comparison: QLED technology supports brightness of up to 2,000 nits – the nit It is a measure that indicates the candela per square meter, that is, the luminosity, while OLED does not reach 1,000 nits.
Although it may seem trivial, this can affect how the TV looks depending on the light. It also affects the colors that are rendered, as as the nits increase, the number of colors that these panels can represent increases.
5. The “burnt pixel”.
The most common failure, especially caused by long-term use or static images, is the “burned-out pixel”. This is a diode that is continuously off, which leads to dead spots or reflections from some scenes.
It is true that OLED panels (and many LEDs as well) have systems to try to alleviate this error – such as pixel shifting, which alternates nearby diodes on color changes – but has not finished fixing. Although it is a problem that stems from LED technology and is inherent in the use of organic components, it must be taken into account.
Quick Battery Tips
Once the advantages and disadvantages of OLED panels are clear, you should bear in mind that:
- OLED is not QLED. Although it may seem obvious, the similarity between the names can lead to confusion. Samsung’s own QLED technology does not have feedback.
- Resolution is not the most important thing. Most of the televisions that are offered already reach 4K, and more if it is OLED, so it is not something you should look at.
- Make sure they have a DVB-T2 tuner. Since March 2020, all televisions that are manufactured must carry this tuner for DTT – since the frequency it used to occupy before, 700 MHz, is now for 5G. But there are older models that are still on sale and may not carry it.
