Hi, this is Wayne again with a topic “Don’t Forget to Clean Your Pixels!”.
Do you ever wonder what the pixel cleaning or pixel refresh option is on your fancy, new OLED TV or monitor? Sadly, it doesn’t Windex your screen for you despite the name, but it could be the most important feature. Your display has, as it’s crucial for mitigating a serious problem, that’s intrinsic to oleds, even if you’re, not an expert on displays, there’s a good chance. You’Ve heard of Burnin, where ghostly visual artifacts stay on your screen. If you’ve displayed a static image for too long, but here’s the thing burning is actually kind of a misnomer. It’S not like something is literally burning after images into your screen. A better name for this phenomenon is image retention, and there are two types of image retention that pixel cleaning is supposed to help prevent. The first is a more temporary issue. After leaving your display on for hours or even minutes, the little transistors that drive the pixels end up reacting differently to the same input voltage as a result, some pixels don’t light up as evenly as they should resulting in image retention. The good news is that this typically isn’t too hard for modern OLED displays to correct.
After a few hours of use, many displays will run a shorter pixel cleaning or compensation cycle that lasts a matter of minutes once you turn them off. What it’s actually doing is adjusting how much current goes through the transistors so that they’ll emit the proper amount of light. The next time the TV is turned on. We should also point out that this temporary retention can also be a side effect of your display heating up from normal use.
And if this is the case with your TV, you can usually resolve it just by turning it off for a little bit and letting it cool down unless it’s in the house with some evidence, you need to get rid of. However, there’s a more potentially catastrophic kind of image retention that your OLED has to deal with in a different way and we’ll tell you about it right after we thank the sponsor of this video circuit specialists circuit specialists provides tools and supplies to the stem community at Competitive prices explore their wide range of offerings, including resistors, capacitors, soldering stations, oscilloscopes and other things, with cool names, leveraging their technology and sourcing expertise.

The second kind of retention is a result of the chemicals in the organic LEDs themselves degrading over time.
This natural wear and tear is irreversible and doesn’t happen evenly instead, which pixels degrade faster, depends on exactly what is being shown on the screen, which is why static images can visibly damage your display if they’re left up too long and too often, this means that the Pixel cleaning Cycles focused on permanent retention, try to make up for uneven wear rather than truly restoring the pixels to their original state. This kind of compensation cycle takes a longer amount of time, sometimes an hour or more and works by measuring how much each pixel has degraded so that the TV can drive it harder accordingly. The next time you turn it on the more a pixel has worn down the more current it needs to reach its proper brightness. Typically, TVs won’t do this until they’ve been used for quite a while, such as a couple thousand hours, but confusingly displays differ as to what they’ll call their short and long pixel cleaning features so be sure to check your products on screen instructions or user manual to Figure out, which is which, if you have a display that allows you to run a refresh cycle manually and don’t run the longer refresh too often as you don’t want to start driving your pixels harder, unless you have to plenty of modern displays, are smart enough to Do this automatically at the correct intervals, once the display is turned off, so our advice is, to only manually run the long compensation cycle. If you can visibly see, there’s a problem and of course it helps if you don’t watch cable news for more reasons than one, but I have to thank you for watching this whole video. Instead, hey like the video, if you liked it dislike it, if you disliked it, the buttons is not just the emotions, although those you can do.
