LCDs used in outdoor situations have many concerns to deal with in addition to any that they might normally encounter during indoor use. Initially some concerns are weather related such as moisture in the air or extreme temperatures. Another concern that is often not understood or just not known about at all is sunlight damage.

Liquid crystal displays use organic components that are susceptible to UV (<400 nm) and IR (>750 nm). These bandwidths of radiation have an observable impact on the organic components in LCDs. Extended exposure has been known to cause a color shift and a washed out look to images displayed with the LCD.

In any case it is important to protect your display from the elements, especially if it is going to be exposed to harsh environments not intended by the manufacturer. One way to do this would be to utilize a Hot Mirror with a UV blocker. This will significantly reduce the amount of IR radiation between 750 nm and 1200 nm, as well as the UV radiation below 400 nm. If the LCD is going to be used outdoors for extended periods then an extended hot mirror may be necessary, which extends the bandwidth protection out to 1600 nm and will help reduce some of the longer wavelength IR damage.

Another concern with liquid crystal displays are their susceptibility to overheating due to excess IR radiation. The LCD is intended to operate within a certain range of temperatures according to the manufacturer’s instructions and outdoor use can lead to higher than normal temperatures. The display being exposed to excessive heat can cause the crystal to become isotropic and fail to perform properly. A hot mirror can help alleviate these concerns as well by reducing the amount of infrared radiation that heats the display.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

"Following our telephone discussion earlier, I have been in discussion with apple and this type of fault or defect unfortunately is not covered on warranty. They have cited certain probabilities which you cannot ascertain if they did happen or notPressure on the LCD – this could happen when the product is carried in a bag

My 2019 q60r samsung started doing this after turning it on one morning. The screen appears to work just fine for a few seconds, the logo shows up, then it fades to pitch black after a few seconds. I can even access the menu just to see it go away immediately. 2 blinks on the red LED, rinse and repeat. Already replaced the PSU board, same result. Now I am about to send the main board to a place where they can diagnose it since no damage is visible. Any ideas before I go on a “rip me off” tour with samsung?

It is fading from the top left side (more or less) and it is moving down to the bottom right corner. The backlight stays on the whole time until the restart (as far as I can tell) and it looks like the power has been cut to the LCD. Disconnecting the controller cable between the main board and the power supply keeps the screen on with 100% brightness and no picture (obviously). Turning it on with one of the T-con cables turns the tv on, you can hear the menu working just fine by the sounds, no matter which one I plug in, but having both of them plugged in at the same time as it should be gives picture and the fading to black as I mentioned above. I already contacted an ebay seller about a new main board but he said he bought it originally to solve the exact same problem, without any luck, so he advised me not to do the same mistake.

If you notice vertical lines on your TV screen, this is a serious issue and should not be neglected. This problem usually occurs if there’s a loose cable wiring, loose or faulty board or a damaged screen.

This is a common problem in TVs and is a sign that your TV panel is failing. But before you call an expert to check the TV, you could try following these steps and check if they work:

If it continues to show lines, you may mostly have to get the panel replaced and replacing the panel can be a costly affair, depending on the TV and its model. LED panels range anywhere between Rs 8,000 to Rs 85,000, while LCD panels range between Rs 6,000 to Rs 25,000.

When the TV has speakers that work perfectly fine but it has no picture, there is mostly an issue with the back-lighting system or the power supply board, which will need to be replaced. In the case of an LCD TV, it works with the help of a backlight that is used to illuminate the picture on the screen. When the backlight begins to have problems, the screen turns blank.

To fix this issue, the backlight will have to be replaced by a TV expert. Another possible reason is that the backlight on the LCD TV which has a power inverter has failed. When this happens, you may need to replace the inverter or the capacitor.

Be it a panel issue or a major technical issue with the TV, resolving these problems is a costly affair. It’s best not to ignore any of these signs and call an authorized TV expert before the problem worsens.

Turn the panel over so that you"re working on the front of the panel. Place the panel on a book or the edge of the table, so that the pins hang over the edge and don"t get damaged while you"re working on the panel.

Select the top film and orient the film so that the arrow on the film label points to the side of the panel with the pins, then peel the protective film layer off the bottom film. This is the side with the sticker.

Peel the adhesive release film away from one edge and apply that edge of the film to the top of the panel panel and press it down with your finger. Gradually peel back the adhesive release film and use the card or roller to work the air out from under the film. If you see an air bubble form, gradually lift the film past the bubble and then reapply.

Use the razor blade to trim the film to the left and right sides and the bottom of the panel. If the film hangs over the top of the viewable area of the panel, that"s fine, but do not try to trim it from the top side, as the IC and conductive traces are easily damaged.

Remove the white backing from the factory graphics and align the bottom edge to the panel. Make sure that the graphics are evenly spaced on the polarizing film. There should be approx 1/32" gap between the bottom side of the panel and the start of the black border. There should be approx 1/32" gap between the left and right sides of the glass, and the black border of the graphics. Stick down the bottom edge of the graphics.

In LCD the light transit through two polarizers, which are arranged perpendicular, then through the liquid crystal layer. The layer can block the transition of the light or change polarization. Finally, the light falls on the color filters, which give it a set colorcreating the image.

The LCD TFT screens are built of thin-film transistors. The transistor is produced by chemical vapor deposition (CVD), based on the use of liquid hydrogen mixture and silicon mixture in an organic solvent, and using the rotation application method of the thin semiconductor.

In the TFT matrix, each pixel is controlled by four transistors, whereone of them is responsible for brightness, and three remain for basic color (red, blue, green). As a result, this solution allows the high resolution, better color and generally higher parameters of displayed images  – comparing to common LCD matrix.

Because of the material the TFT is built from, which isglass, TFT displays havelow mechanical toughness,so can be easily damaged. The most popular damage of TFT is:

The majority of damage occurs during the assembly process in the end user devices. Too much pressure on the fragile TFT construction can damage the structure of the liquid crystal or electric lines.

The module can be held strictly by the housing, and the unnecessary thrust on display should be avoided. The disassembling of the display housing is not recommended, because this process is very destructive and in most cases, it will leave you with a damaged TFT .

So if the fear of the mere possibility of burn-in is your primary concern, the decision is simple: Buy an LCD-based display instead. But know that you"re sacrificing the best picture quality that money can buy. Here are some points to keep in mind:

To repeat, you can watch those channels, play games or whatever else to use your TV as a TV, your phone as a phone, etc. You just shouldn"t watch only those channels, all day every day. And if that sounds extreme, know that emails I"ve gotten from readers about burn-in always have some variation on "well I only watched that channel for 5 hours a day." If that sounds like you, get an LCD.

To remove image retention, the TVs can also perform "refreshers" on a daily or longer-term basis. On Sony TVs the feature is called "Panel Refresh," and LG calls it "Pixel Refresher." It can be run manually if you notice image retention or, in the case of LG, you"ll get a reminder to run it after 2,000 hours.

With TVs, beyond the methods outlined above, there"s not much you can do to reverse burn-in. In theory, I suppose, you could create an inverse image using Photoshop and run that on your screen for a while. This could age the rest of the panel to more evenly match the "burned in" area. Figuring out how to do this is well beyond the scope of this article, and you"d need to be pretty well versed in Photoshop to even attempt it.

The most comprehensive independent tests for burn-in on TVs was run by the aforementioned review site RTings. In August 2017 they began a burn-in torture test with LCD and OLED TVs, followed by a "real life" torture test in 2018. They stopped regularly updating the test in 2020, but that was after the equivalent of 5 years of normal use on multiple TVs, and still they felt that most people will never have an issue with burn-in.

Before you check it out, keep in mind what they"re doing is not normal use. You"d have to be trying to wreck a TV to make it look that bad, which is literally what they"re trying to do. That said, the information is still valuable, and the main takeaway is that OLED is indeed more susceptible to burn-in than LCD.

With OLED TVs, it"s something to keep in mind if you"re a TV news junkie, or only ever play one video game. Keep an eye out for image retention or uneven wear. If you spot it, perhaps switch up your viewing habits, adjust the TV"s settings, or run the pixel refresher a few times. And if you watch content with hours of the same static image each day, or just keep CNN, Fox or CNBC on in the background all day, you should probably get an LCD TV.

If you spend long enough debating the merits of LCD vs. OLED display technologies, eventually, someone will touch upon the subject of the dreaded OLED screen burn in. The point made is that OLED displays will inevitably suffer from horrible-looking artifacts over time, while LCD and new technologies like Mini-LED won’t. But like most of these debates, you’ll probably hear as many overblown anecdotes as you will actual facts about the issue.

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

The cause of all screen burn in is the varying lifecycle of a display’s light-producing components. As these parts age, their brightness changes, and therefore the panel’s color reproduction gradually shifts with time. Although this can be mitigated somewhat with clever software, all displays experience some color shift as they age. But with burn in, some parts of the screen age faster than others. This can gradually shift the perceivable colors of the screen in one area more than in another, leaving what looks like a ghost image behind.

With modern smartphone and smartwatch technology, screen burn in can manifest due to the different life spans between the red, green, and blue LED subpixels used in OLED panels. As we mentioned before, areas of the display that seldom change, are bright white, or are often black and switched off, such as navigation buttons or the notification bar, are the most likely areas to notice this issue. You may also notice the effect in darkened status bars designed to hide display notches.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

If your screen is already burnt in, there’s not much that can be done to undo the damage. Some apps on the Play Store claim to reverse the problem. These will end up “burning” the rest of the screen to match the colors, which isn’t a real solution.

All that said, screen burn in isn’t something that should concern many users if they’re looking to buy a new OLED smartphone. Modern panels have much longer lifespans than early OLED smartphones, and even then, burn in was rare. Just don’t leave a static image on the screen 24/7 with the brightness set at max.

Light is a very common cause of damage to collections. Many materials are particularly sensitive to light: paper, cloth, leather, photographs, and media (inks, colorants, dyes, and many other materials used to create objects and art). Aside from fading, there may be damage to the physical and chemical structure of materials. Light and ultraviolet radiation (UV) provides energy to fuel the chemical reactions that lead to deterioration and while UV is blamed for most of this damage, visible light is also problematic.

Intensity and long exposure times can lead to fading or changing colors in dyes and colorants. Ultraviolet radiation will lead to weakening, bleaching, and yellowing of paper and other organic materials. All of these changes can diminish readability, affect the aesthetic appreciation of artwork, and impact access to the information contained therein. Even if you take a faded photograph down and store it in the dark, it will not return to its original appearance and will continue to fade when taken out again.

If no light or UV meter is available, it is possible to estimate the damage that might result to an artifact from particular intensities of light and lengths of exposure. This can be done using the ISO’s Blue Wool standard cards, available from a number of conservation suppliers.

More than other measurements, the Blue Wool cards visibly demonstrate the destructive powers of light. Because these cards provide a standard against which subsequent fading can be judged, they can be used to convince skeptics that light really is a problem. Each Blue Wool standard contains eight samples of blue-dyed wool. Sample 1 is extremely light sensitive, while sample 8 is the most stable dye available (although not permanent). Sample 2 takes twice as long to fade as sample 1, sample 3 takes twice as long as sample 2, and so forth. For more information, see “Light, Ultraviolet and Infrared” by Stephan Michalski in Resources.

To demonstrate the degree of fading caused by the intensity of light in a particular location, cover half of the card with a light-blocking material to protect it completely from light damage (or cut the card up into strips reserving one as a control). Note the date and set out the Blue Wools in the desired location. Check periodically (every couple of weeks) to determine how long it takes the various samples to fade. Since the sensitivity of the first few samples on the card corresponds to light sensitive materials such as watercolors and textiles, the results will give you a general idea of the amount of damage you might expect if materials were exhibited for the same period of time at the current light level in that location.

There are two sources of light: sunlight and electrically produced light. As a primary light source, sunlight is not recommended. It is too intense, causes extensive fading, and has a high UV component, which also causes damage at the chemical level. Different types of electrical lighting may be required for storage, staff, public, and exhibition spaces within libraries, museums, and archives. It is helpful to understand the available options and characteristics to select the best option for lighting these spaces. The most common lamps found, especially in storage and exhibit spaces, are:

Since UV radiation is the most energetic, and thus the most destructive, it is easy to assume that if UV radiation is eliminated, damage will cease. Unfortunately, this is not the case; visible light also causes damage. While exposure to UV can be eliminated from exhibit and storage areas (and diminished in public spaces with filtering and lamp selection), reducing visible light requires different strategies.

Protect any materials that may be particularly susceptible to light damage, such as framed color photographs or watercolors, by displaying away from any direct light (sunlight and spotlights) and glazing with UV blocking glass or Plexiglas or by displaying good quality facsimiles.

mounted inside the window from hooks, magnets, or a separate frame (the panel must be cut larger than the window glass, so that all light passes through it).

While on exhibit, collections are most susceptible to light damage and care should be taken to protect these materials. The intensity of light and the length of time the materials will be on display are the primary factors and need to be considered together.

If the light levels are to be higher than 50-150 lux, the length of time on exhibit needs to be decreased accordingly. When making the decision about time on exhibit and light levels, be aware that low light levels for extended periods of time cause as much damage as high light levels for short periods. We can measure the damage to materials in direct proportion to the light level multiplied by the time of exposure, measured in lux hours (lx h). For example, an object lit for 10 hours a day at 50 lux for 100 days would have a light dosage of 50,000 lx h. Ideally, light-sensitive materials would only have an annual exposure of 50,000 lx h, regardless of whether they will be displayed annually or not. When considering how much and how often an item is to be on display, always keep in mind that light damage is cumulative and irreversible.

Using lux hours to track light exposure provides useful and concrete information on how bright exhibition lighting can be by clearly showing that the same amount of expected damage occurs with brighter light and short time as dimmer light and long time. In order to use this principle effectively, good records of exhibition durations and actual light levels must be kept.

All light is energy and the energy that light provides fuels destructive chemical reactions that contribute to the deterioration of collections in libraries, archives, and museums. Light also damages bindings, photographic emulsions, and other media, including the inks, dyes, and pigments used in many library and archival materials.
