Oled what does it mean

This is because it's more cost-effective to make "more" being the key word there. The apparent downsides, such as light output and color accuracy, don't seem to be issues.

Sure, they're not as bright as the brightest LCDs, but they are still very bright, and the current models have the same color saturation as the best LCDs. Speaking of apparent downsides, here's another: burn-in. Or at least, the potential of burn-in. Burn-in is when an area of the screen can't produce the same amount of light as the rest. It's essentially more worn out than the rest.

That section might look like it has a bit of a shadow, or in extreme cases, you can make out the shape of what burned in. For example, a shadowy after-image of a news station's channel logo might be visible when you change the channel. OLED TVs are susceptible to burn-in, but in all but the most extreme cases what you'd see is more accurately described as "image retention. Burn-in is permanent, and would only happen if, say, you only ever watch one channel for 8 hours a day every day.

As long as you use your TV to watch a variety of content i. They're the same image, but we've circled the section with the logo on the right to highlight it. To see it better, turn up your screen's brightness and look for a rectangular shape. In person, it's more visible in a dark room, but much less visible with moving images as opposed to a test pattern.

Since it disappeared after running LG's Pixel Refresher , this is an example if image retention and not burn-in. We don't think burn-in will be an issue for most people, which is why we still recommend OLED TVs for people looking for the best image quality. If you're curious about burn-in and image retention, check out OLED screen burn-in: What you need to know. But wait! I hear you exclaim. Wouldn't that mean the LG's whole TV will die out at the faster blue rate, since every pixel incorporates blue?

At least, that's how long they expect the panel to last. On most modern TVs of any technology, it's the power supply that dies long before the panel. Not to mention that a TV bought today probably won't be able to be connected to anything in 22 years just like how TVs circa are obsolete today. But that's for a different article. There are rumors that might be changing in the near-ish future, but for now it's still LG's game.

Outside the US, companies like Panasonic and Philips do the same. One of the most interesting current LCD technologies is quantum dots. These microscopic particles glow a certain color when you give them energy. Many new TVs have the photo luminescent version, with dots that glow a specific color when hit with light usually the light from an LED backlight.

Down the road a little farther is the electroluminescent version of this technology. The LG TV line-up has been strong so far this year. We heard directly from LG Display itself that an even smaller inch size is on its way for too. There's also the more affordable, mid-spec Panasonic JZ Although it's not just the biggest brands that have OLED offerings. OLED TVs are definitely getting cheaper, but they're still a long way from what we'd call affordable.

The scarcity of OLED TVs on the market has meant that those small number of players in the market are more or less free to charge exactly what they want. An increase in competition, though, is helping to change that, as is the introduction of a new inch OLED size and a scaling up of production helping to drop the cost of budget OLED TVs.

The arrival of inch OLEDs down the line would certainly help matters too. It's definitely worth keeping an eye out for end-of-year sales.

Black Friday and Cyber Monday usually have numerous good deals on OLED TVs — and given their usually high starting price, you can often get hundreds discounted at the right time.

Cheaper OLEDs, though can still see notable price cuts that bring them more within reach of mid-range buyers. Burn in, or image retention, is when an image or sequence is played so often and continuously on a television set that it leaves a permanent mark on the panel — obviously not ideal for a home television.

You don't particularly need to worry, as it largely happens only when displaying a static image or sequence on repeat, as with a display unit in a showroom or retail store. You should get several years warranty, anyhow, and we don't see many home cinema fans using their OLED TV in this way. TV makers like LG are also working to limit the risk of this, with screen saver features, a Screen Shift function that "moves the screen slightly at regular intervals to preserve image quality", and "Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention" via LG.

But if you're planning on leaving your TV for countless hours at a time — say, to parent the children in your absence, or to play the same looping video over and over — then OLED may not be the right panel technology for you. OLED is an expensive panel technology that has finally managed to gain traction — after spending so long as an outlier that we wrote an opinion piece in about how the technology might be dead.

Obviously that didn't turn out to be the case. We've seen plenty of stunning OLED models hit the market this year alone. Although price points are still taking an age to drop within reach of regular consumers. But just because OLED isn't affordable yet doesn't mean it's not getting better. One example is ink-jet printing, which makes use of soluble OLED inks that can be deposited using huge printers.

This process is faster than the current evaporation process, and has almost no waste of materials. While there are still some challenges to overcome, it is expected that printed OLEDs will start entering the market soon - starting with TVs and monitor panels.

The first OLED devices used so-called fluorescence emitters 1 st -gen emitters. As of today, very efficient red and green phosphorescence OLEDs are available on the market and most OLED displays make use of these emitters to create highly efficient emitters.

An efficient and long-lasting blue emitter material has proven extremely hard to produce, and companies are still struggling to develop this material. Any much-anticipated success in doing so would surely have a dramatic effect on the power efficiency of OLED displays. Testing an OLED device involves simultaneously measuring its electrical and optical properties to generate a current-voltage-luminance IVL curve.

This allows the power efficiency and brightness to be characterised. Lifetime testing is also important to ascertain how quickly an OLED will degrade over extended use. The future of OLEDs seems bright as their presence in the smartphone and TV markets is continuously growing, in addition to other markets such as wearables, VR and more.

OLED technology is still an emerging technology, and many avenues are still open for new materials to be found and new processes to be developed that could further enhance OLED displays.
