Image retention vs burn-inĪlthough it may be easy to think temporary image retention and burn-in are the same, they're actually different. There are also two popular types of LCD panels: VA and IPS, and IPS panels are generally more prone to image retention, but that doesn't mean VA panels are immune to it, either.
OLEDs tend to suffer more burn-in than LCD panels, but once again, it's all about the luck of the draw and you can still receive an LED-backlit LCD TV with severe image retention. This is why it's most noticeable when watching content with static elements for long periods. However, between each type, if the same image remains on-screen for a long period, then the pixels remain in that position even after the on-screen display changes. Each type uses different technology to display an image an OLED can individually turn on each pixel, whereas pixels in an LCD panel need voltage to be applied, and they rotate to allow light through, producing the image. Modern TVs use one of two popular panel types: Organic Light Emitting Diode (OLED) or a Liquid Crystal Display (LCD) panel lit by LED lights. Warning: The video contains flashing images.Īdditional Information What causes image retention? Below you can see what a standard 15% gray image and our test video look like.

We connect our camera to the PC and use software that automatically takes pictures every two minutes.
To stay consistent across all TVs during testing, we adjust the backlight on the 15% gray scene to 2 cd/m², with the TV calibrated and without any local dimming setting enabled. All the photos are taken automatically. Although this test doesn't give us the exact time that the image retention disappears, it gives us a ballpark number of how long the elements stay on the screen. Most TVs with image retention issues will only show signs of it immediately after the video finishes, and it quickly disappears. Every two minutes after that, there's a 15% gray image of which we take another picture to see if there's image retention 2, 4, 6, 8, and 10 minutes after the high-contrast elements have disappeared. Then, the video continues to display flashing red, green, and blue so that the pixels return to their 'normal' state. Image retention is most noticeable at this point since it's immediately after the static images have left the screen. Right after the video finishes, it displays another 15% gray image and we take a picture to compare to our original image. Then, a 10-minute clip plays with high-contrast static images of our company logo. First, it displays a 15% gray image and we take a picture of it to use as a reference. Everything that we need is included in our image retention video. If that's the case and it really bothers you, see what you can do to get the TV exchanged for a new one, but there's no guarantee that one won't show image retention either.Īs for testing for temporary image retention, it's a pretty simple process. Temporary image retention can vary from TV to TV, even if they're the same model, so you may get unlucky and buy a unit that shows signs of it right when you first open it. However, we don't expect this to be an issue for those watching movies or if you watch content with varied elements even a sports broadcast, with its static scoreboards, changes things up with replays and commercials. You won't notice the image retention while you're watching that particular content, but it will only be noticeable when something else appears on-screen, and even then, it may only last a few moments. Whether you want to use it as a PC monitor, to play video games, or to watch cable broadcasts like the news or sports, each have a ton of static elements that can cause temporary image retention. It's important to have a TV that doesn't show any signs of image retention if you watch content with a lot of static elements.
