Image storage (burn-in): Everything you need to know

Burning in the image storageWhile this doesn’t seem to be a problem that occurs as often today as it used to – especially in times of CRTs – image retention is still a pain in the neck that can easily happen to you.

The problem of image storage becomes noticeably problematic with OLED screens even with the best OLED televisions. Fortunately, there are fixes for OLED image retention, as well as rare issues with LCD image retention.

What is image storage?

Image storage (sometimes commonly referred to as burn-in) that tells us what’s going on here. In the simplest case, this is the case when a previous image or impression of a color (or other colors) remains on a screen or is burned in.

We can also call this ghosting on a physical level that can theoretically leave a lasting impression.

We can also express it through discoloration. Image storage can be limited or most noticeable in certain pixels, or it can come from faulty elements or element drivers (usually in the case of LCD image storage).

It can also be seen that a tri-color element is either glued to one or two colors or a different color is rendered overall. This can happen if the color temperature is too high or the contrast ratio is almost full, which leads to saturation with corresponding physical overheating.

Image Retention Vs. Branding: The Difference?

When burning in, not only the image is preserved. However, image retention is the best known and all too common form of stoving, so that these terms are used synonymously. However, fixation of the image retention is generally considered possible, whereas the burn-in can be a permanent and complete deterioration.

Image retention is also called image persistence. The difference between these two terms is therefore the temporary nature of image retention. It is kept, but not branded. Burn-in occurs on public TV sets that may be stored on a single channel for 24 hours, e.g. B. a news or weather channel or a screen with exchange rates.

However, branding is most often an artifact of old CRT or plasma screens, while LCD image retention and OLED image retention are the issues of the current age that we want to address and fix.

Prevent image retention and burn-in

The simplest solution to every problem is the old saying: avoid the danger that has not yet occurred.

Manufacturers are also aware of the problem – and we’ll talk about the steps they took to better protect you from burn-in and image storage. Knowing the best practices for taking care of your phone, TV, and displays is very important.

The first thing to do, of course, is to make sure you don’t leave your displays on for no reason. This also helps to save electricity costs and possible damage, but also prevents burn-in.

Image calibration also protects you a lot, especially on 75-80 inch TVs where the damage is most clearly visible. In particular, the brightness and contrast ratio should not be too high (the greatest damage is caused by contrast ratios of almost 75%), ideally with even flashes on the screen.

How do manufacturers reduce image retention and branding?

In addition to the paragraph above, different manufacturers use different methods to protect their products. In many cases, proprietary technology has been developed to help.

Samsung uses a so-called pentile matrix technology in the sub-pixel arrangement. It drives the LED with less power (due to a larger blue sub-pixel), which effectively extends the life of the AMOLED display, which means that the speed of occurrence for color shifts and burn-in processes is reduced.

There are also software-based solutions, mainly for smartphones and smartwatches, but some smart TVs have implemented them too. Check to see if your phone has an always-on display or a burn protection option (usually in Android Wear). These move the image or certain pixels slightly and reposition it periodically so that no pixels maintain the luminance for too long and each one shows a different color at more or less the same time.

Implement an image retention fix

Ultimately, the best 4K televisions out there are prone to burn-in and image retention. Prevention is the way to get your best foot forward. However, if you notice a terrible mess on your hands, here are some suggestions for possible corrections to image storage and a few words on how to implement them.

The first is a solution through a “Lifehack” proposed by Apple itself.

If you create a pure white screen (created in Paint, Photoshop or another graphics application) and save it as a high quality displayable file like JPEG or PNG in high quality, use it as a screen saver. (Yes, desperate times require screensavers).

Set the display brightness to a very low setting and display this image for as long as possible (theoretically, this image should be displayed for the same time if you know how long the image has been displayed with retention).

A similar fix for the storage of LCD images involves the use of visual white static that stays on between 12 hours and a full day. The swiping motion of the two basic colors black and white helps to essentially wash off the screen. For this reason, some manufacturers even offer a wiping option.

Many different websites require different image storage fixes, which are basically variations of the same techniques. However, there is also the JScreenFix website, which is available for free or at a low price, and uses various algorithms to not only fix screens that retain burn-in, but generally improve lifespan.

Finally, if nothing else; You may need to have your screen replaced or replaced.
