lcd panel bleed brands

Sony states that this is a common phenomenon on all LCD TVs.Backlight Bleed is when some screen areas are lighter than others due to spillover from a backlight or uneven backlighting.

Perhaps you still want to get an LED TV due to the lower price point. In that case, your best bet is to read reviews to determine if others are experiencing backlight bleed issues with a particular TV model.

When light bounces off any surface around the edges of the screen, it can result in Flashlighting, or extra light at the edges or corners, making the lighting of the LCD panel uneven.

Clouding occurs when layers of the screen become uneven due to misalignment, damage, pressure, or temperature changes. The misalignment results in the light not being evenly distributed.Flashlighting is the type of backlight bleed experienced at the corners or edges of a screen.

Backlight bleed goes by various names, including light leakage, screen bleed, light bleed, clouding, blooming, mura, banding, and un-uniform brightness.

Excessive LED backlight bleed can be caused by the following:Temperature changes result in materials expanding or contracting, including the LCD panel or frame.

Temperature changes may result in some components moving or warping slightly. Backlight bleeding could be reduced after either cooling down or warming up, depending on how the TV was designed.

Some possible ways to fix LED backlight bleed or make it less noticeable include:Give it time: Some new TVs experience an increase in backlight bleeding which can slowly disappear after a few weeks or months.

Reduce screen brightness: Reducing brightness can reduce the backlight intensity, which may cause the backlight bleeding to be less noticeable or even impact the screen"s temperature.

Enable local dimming or LED dynamic control if your TV supports it: Reduce backlight bleeding for darker scenes by dimming darker portions of the scene.

Use a microfiber cloth to gently rub the portion of the screen where the backlight bleeding is prominent: This may help with clouding by evening out an uneven LCD panel.

Take apart the TV and apply electrical tape around the edges of the LCD: While likely to void your warranty, this could reduce light escaping and reflecting around the edges of the screen.

If the backlight bleed is not too distracting, there"s nothing to worry about. Backlight bleed typically will not get worse over time on its own. However, frequently moving a TV around or improper handling could result in bending the tv frame or components, resulting in backlight bleed.

Some manufacturers do not allow returns based on general backlight bleeding, which is typical of LED backlighting. For example, Sony considers bleeding that is only visible on "black images and in a dark or very dim room" to be considered within specification. Are you experiencing backlight bleeding in bright scenes and a well-lit room? If so, you may be able to return the TV to your manufacturer for a replacement.

To determine the maximum amount of backlight bleed possible with a TV, you can: increase screen brightness, turn off auto-brightness, view the TV in a dark room, and disable local dimming. These are not settings for optimal viewing but can be used for testing the worst-case scenario.

I"ve just imported my LG UM95-P from Amazon Spain it"s a beautiful display but it has some minor but very distracting backlight bleed I have less than 30 days to decide if I want to keep it:

The picture bellow exaggerate the perceived backlight bleed under normal viewing conditions only the bottom left is visible and only when the screen is black:

Overall I"m very happy with my LG and by comparison to many LG UM95-P owners I have very little bleed but the effect when viewing a dark image a film or game (Amnesia: The Dark Descent) being a prime example is like the glow of a small campfire to the left of my peripheral vision which breaks the sense of immersion.

As these screens are well known for this issue a replacement is unlightly to solve the problem, I have attempted to fix the problem myself using Credit Card Light Bleed Fix as seen in this video:

Although it did not fix the problem nether did it worsen it pushing at the bottom left of the screen temporarily removes the light bleed, I even went so far as to try a suction cup which yet again had no effect :(

Backlight bleed and IPS glow are two common monitor issues that can impact your viewing experience. Although they have fundamentally different solutions and causes, they do look extremely similar. It can be helpful to identify which condition you’re dealing with so you can decide how to proceed.

On the other hand, backlight bleed often shows up on the edges as well as the corners of the monitor. Some monitors will only have bleeding in a single corner. Others might have different intensities of bleeding on every edge of the screen.

Do note that it’s impossible to get IPS glow unless the monitor uses an IPS panel. This is because IPS glow is, unfortunately, a quirk of the panel technology. You ideally wouldn’t purchase or keep a monitor that bleeds since backlight bleeding is a defect.

Once you’ve spotted the problem, it might not actually matter whether it’s IPS glow or backlight bleed. There is no fix for either condition–-they are both caused by a lack of quality control and poor manufacturing technique. Your best bet is to return the monitor and order a new one.

Although we covered how you can tell the difference between backlight bleed and IPS glow, there’s more to it than that. They have similar, but unique causes that could impact your future monitor purchases.

If you’re expecting a monitor to have none of this natural glow, then don’t get a display with an IPS panel. IPS is a kind of LCD technology that uses a backlight. It’s this backlight glowing through the panel that causes the IPS glow as we know it.

Since it’s partially related to the screen panel and how it’s installed, the exact same model of IPS monitor could have wildly different degrees of IPS glow. In that way, it’s very similar to backlight bleed.

The cause of the backlight bleed is a problem with the way the screen is installed. The term “backlight bleed” explains exactly what is happening; the backlight is bleeding through the screen. This happens either by having the light pressed too close to the screen or by having an improper fit between the screen and the frame.

Since backlight bleed is directly related to having the backlight shine through, it won’t change intensity just because you look at it from a different angle. IPS glow does change intensity, both by different viewing angles or by distance from the display. If you think about it, this makes sense. IPS glow has to do with the screen technology and not just the backlight.

A very reasonable way to solve IPS glow and backlight bleed is to simply avoid playing in the dark. This is going to be the most effective tactic because dark environments make excess light more obvious.

The other solution is to try to stop the “excess light”–-in other words, turn down the brightness. Your monitor should have a similar brightness to your surroundings. If you’re dealing with backlight bleed, though, it’s completely reasonable to turn it down a bit.

In a well-lit environment, it’s very possible that you will never notice IPS glow or backlight bleed. Only very severe cases of IPS glow should be noticeable at all, generally speaking. If you’re seeing IPS glow even with the lights on and without staring at a black screen, you have a defective monitor.

The solution, in that case, is just to return the monitor and get a new one. It’s the same for backlight bleeding, too. Any monitor with IPS glow or backlight bleed that’s serious enough to bother you in an ideal environment has a serious enough problem that you should return it.

Although there’s no consistent way to remove backlight bleed, you can try to loosen the panel frame slightly by moving it around with your hands. Honestly, though, it might not be worth it. This only has a chance of working if the bleeding is caused by the panel frame pushing into the screen, and you could damage the monitor more.

As for backlight bleed, you would have to avoid purchasing any type of LCD monitor. That isn’t a very realistic option, since LCD monitors dominate the market. Plus, LED monitors can also have backlight bleeds. It just isn’t as common.

An easier solution that works for both backlight bleed and IPS glow is to spend more on your monitor in the first place. It can feel painful to spend a lot of money on a display, but it’s the best way to get a quality monitor.

Remember: severe IPS glow and backlight bleed are both signs of a low-quality monitor. Don’t accept them as the status quo, and don’t buy a cheap monitor expecting it to be well-crafted.

Backlight bleed is, hands down, a worse condition than IPS glow. It’s always the result of poor manufacturing and/or another monitor defect. Usually, backlight bleeding is more intense (which makes it more disruptive) and there’s no consistent way to change or fix it.

IPS glow is never really a serious condition, except in rare scenarios. At that point, it would also be considered a defect. Still, backlight bleed is generally worse even in that scenario.

At the very least, IPS glow is often restricted to the corners of the screen and is symmetrical. Backlight bleeding can show up around all of the edges of the screen and can be very distracting because it’s not always even.

There are also plenty of ways to reduce IPS glow since it’s rarely as bright as backlight bleeding. IPS monitors naturally have lower contrast ratios. They also have wide viewing angles, so there’s no reason you can’t tilt the screen slightly.

All in all, backlight bleeding will cause the most severe lighting problems with your monitor. If you’re dealing with a serious problem, though, just return or replace the monitor. There’s no real solution, and a defective monitor is worth replacing!

This is also known as “flashlighting” (backlight bleed in the corners of the screen) and “clouding” (irregular patches of light remaining visible when the screen is supposed to be black).

If you’ve bought a new display that shows significant backlight bleeding, there’s a fair chance that you will be able to get it replaced. However, different companies have different policies when it comes to this type of issue, so don’t expect it to be a smooth ride.

As mentioned in the introduction, there are two major ways in which backlight bleeding can manifest, flashlighting and clouding. Generally, clouding is more prevalent in larger displays, while flashlighting can occur in both larger and smaller ones. Light bleeding along the edges is also common, although far less noticeable.

Slightly loosen the screws on the back of the display. Sometimes, clouding and/or flashlighting occur as a result of the panel warping due to the screws being too tight. Turning each screw half-way counter-clockwise should do the trick.

Take the microfiber cloth and gently rub the areas where the bleed appears in a circular pattern. Apply only so much pressure that you can see the reflections in the screen warp slightly.

If you’ve done all of the above and the bleed still persists, try giving the display a day to settle. If after that time, the backlight bleeding is still there, try repeating step number four and it should go away eventually.

Let’s consider the worst-case scenario — the seller won’t fix or replace the display, and the above steps have not helped. In this case, the only thing that you can do to make the bleeding more manageable is to turn down the brightness.

Of course, this is far from an ideal solution since it will inevitably detract from the visual quality, especially if you own an HDR-capable display. But unfortunately, this is the only way to reduce the bleed if the above steps did not help.

Sadly, backlight bleeding will always occur in displays that use an active backlight, so the only way to avoid it entirely is toinvest in an OLED display. Of course, this is not an option for everyone as OLED displays are extremely expensive and will remain so for the foreseeable future.

So, rather than thinking about how to avoid it entirely, think about how you can get your hands on a display with minimal backlight bleeding. This is as simple as reading reviews, customer and professional alike, of the monitor/TV that you’re thinking about buying.

Key Takeaways:Backlight bleeding commonly affects LCD display (Liquid Crystal Display) monitors with a VA(Vertical Alignment), IPS(In-Plane Switching), or TN(Twisted Nematic).

Light leaking on your monitor edges is not only annoying but can also be distracting for gamers. Backlight bleeding is a monitor defect in modern monitors where the light source is shining through the screen edges. This defect is commonly caused when the backlight in a monitor is not completely sealed off due to poor quality control or manufacturer design issues.

Backlight bleeding commonly affects LCD display (liquid crystal display) monitors with a VA(Vertical Alignment), IPS(In-Plane Switching), or TN(Twisted Nematic). It’s not easy to spot a backlight bleed. A screen bleed is commonly visible in low light conditions, like using a monitor in a dark room.

Backlight bleeding is a display defect that commonly occurs in LCD screens that use a light source from a panel. This panel should ideally block excessive light that is not required when displaying a picture or video on the screen.

Sometimes, not all the light gets blocked by the panel, leaking out to the edges of the frame. This phenomenon is called backlight bleeding. Backlight bleeding can appear in the following ways:

This backlight bleed is visible on the edges of the monitor. In severe instances, the edges of the monitor get more light, while the center is dimmer.

Unlike your common backlight bleed or clouding, an IPS glow occurs in IPS monitors. An IPS glow manifests as a faint glow visible in certain angles, especially when watching dark content. Depending on the type of panel, the IPS glow is unavoidable but tolerable. The glow is visible in corners.

If you are unsure if you have a backlight bleed or IPS glow, you’ll need to perform a backlight bleed test. Fortunately, it’s a simple and straightforward process.First, ensure your monitor is in a dark room. Turn off the lights. A black monitor and darkroom make it easy to spot an IPS glow or backlight bleed.

Set up a black screen or open a black image and inspect where patches of light are visible around the edges or corners of the monitor. If you cannot spot any IPS glow or backlight bleeding issue, your monitor is fine.

Before you perform this task, make sure your monitor is turned off. Give it a few minutes to cool off.Loosen screws located at the back of your monitors slightly. At times, flash lighting or clouding happens due to panel warping when the screws are tightly fastened. Turn the screws halfway, counterclockwise.

If the backlight bleed is still visible, take a microfiber cloth, and in a circular motion, rub the areas where the bleed appears. Make sure you only apply as much pressure to see reflections on the screen warp slightly.

If you perform all the steps above and the backlight bleed persists, let your monitor sit for a day. If the bleed is still visible, repeat the above steps. The bleed should eventually fade away.

Backlight bleed is characterized by light leaking around the edges or corners of an LCD. This is due to the way these displays work; they use a light behind the panel that faces the display.

Backlight bleeding is simply some of the backlight leaking through. There are no ways to completely remove this, though it can be reduced in some scenarios. If you have too much backlight bleed, you might be able to RMA your display.

Your LED LCD, whether it’s a TV or a monitor, uses a LED backlight to create the image through the liquid crystal display panel. Some of that light might not get entirely blocked around the display’s bezels, which results in backlight bleeding.

Generally, some minor backlight bleeding is expected due to the nature of the display technology, and it is entirely tolerable given you won’t even notice it most of the time.

However, sometimes the backlight bleeding can be rather eye-searing and, in this case, you may be able to return your display and get a new model or a refund depending on the manufacturer’s RMA policy.

The former is common for curved VA panel displays and is often referred to as the ‘batman’ logo pattern (image above). Usually, the glowing patches are only visible with pitch-black scenes and unnoticeable when watching regular content.

In short, if you are experiencing too much backlight bleeding, you should try to RMA your display. In case the display manufacturer won’t accept it, you will have to get a new monitor/TV, preferably with an OLED panel that doesn’t suffer from these issues.

In case the backlight bleeding doesn’t bother you in real use, it’s not worth returning or replacing the display as another unit might have even worse backlight bleeding or other defects, such as dead or stuck pixels.

Unlike backlight bleeding, the intensity of IPS glow can be reduced by changing the angle or the distance you’re looking at the screen or by decreasing screen brightness and adding ambient lighting.

Hello, over the past few years, I have used various Lenovo laptops and 4K LCD screens from established monitor companies like LG and BenQ. However, they always have some sort of backlight bleed, IPS glow and/or blocky artifacts when playing movies with dark background. Apple"s products, on the other hand, have no such issues. Is getting a display without such issues for the PC a lottery? The so-called "fix" by lowering the brightness or avoiding the use of monitor in a dark environment to hide the issues is kind of defeating manufacturer"s claims that their monitors can produce high brightness level and good for movie watching. I read that OLED displays have not such issue but I hesitate to buy them due to potential burn in.

The IPS Glow is a "glow" effect which is present on the corners of an IPS panel whereas Backlight Bleeding usually appears along the edges of a monitor. It is most visible when viewing dark images in a darker environment. The amount of the IPS Glow depends on viewing angles, the distance to the IPS panel, the ambient light, monitor brightness settings as well as the manufacturing quality. Each individual unit will vary in terms of the IPS Glow. Backlight Bleeding does not change when viewing at an off angle. The IPS Glow is technology-related and can never be completely prevented or eliminated.

The IPS Glow and Backlight Bleeding can really be exhausting when buying a new monitor. It is most visible on the edges of an IPS monitor in a darker environment (and especially when combined with it higher monitor OSD brightness settings). It can appear with a brownish, light bluish, yellowish, or greyish tint and the amount and color can differ in each individual unit. Backlight bleeding refers to areas of bright light on the monitor that are primarily visible when viewing dark or black screens in the darker environment. These light areas usually appear along the edges or corners of the monitor.

Long answer: The IPS Glow is strongly depending on the viewing angle, on the distance, on the panel frame construction as well as on the ambient light. The brighter your environment, the less visible the IPS glow. The IPS Glow also can differ in terms of the IPS Glow color tint. Current WQHD high refresh rate gaming monitors have a brownish or bluish IPS Glow (depending on your individual unit) whereas 100Hz ultrawide gaming monitors have a more yellowish IPS Glow (LG Panel built in the Asus PG348Q, Acer X34A, Alienware AW3418DW, Acer X34P). Some other IPS panels with 60 Hz have a more white/grey tint in the IPS Glow. The IPS Glow is visible only in the corners/edged of a screen. However, the IPS Glow also is visible in bright image content or rather on a fully white screen when looking from an angle. At a harsher angle, it looks like the panel is coated with an oil filter.

The amount of backlight bleeding increases the more the panel frame pressures against the panel/display. It also can increase the amount of the IPS Glow when it pressures against the panel/display near the edged.

Backlight Bleeding otherwise occurs when the led backlit behind the panel or borders is placed faulty or when the panel frame construction causes too much pressure on the display. Unlike the IPS Glow, it does not depend on the distance to the monitor or the angle at which you look at the display. Sometimes, it is possible to lose the panel frame also a bit. In this case, you can observe that the amount of Backlight Bleed will decrease. However, Backlight Bleed often is visible also near the edged, because the panel frame at this part is mostly tighter and stiffer compared to the bottom center for example.

Already during the production, it is decided if a panel has bad, acceptable or very good IPS Glow and Backlight Bleed conditions. A panel has different layers included the anti-glare coating surface and the inner panel housing which is made out of metal. In the end, it depends on how well a panel is manufactured and how much pressure and tension the individual panel has. Incidentally, it is currently technically not possible to build an IPS panel without IPS Glow.

To test your individual unit for IPS Glow you simply just have to open a full black screen on your monitor and dim your ambient lights in your room (Lamps, lights from outside, windows etc.). The darker the room the more IPS Glow and Backlight Bleed you will be able to observe. You can follow this link where I have created a full black screen video on YouTube with a length of 30 minutes.

First of all, you have to find out where your personal tolerance level lays. Are you using your monitor often in a pitch black or dark room? Does the IPS Glow disturb you while playing games? How close do you sit to the monitor? Is an IPS panel the right choice for you?

Depending on with which panel type or rather how strong the contrast is with which you are looking for test images and videos the IPS Glow and black level can differentiate. The less contrast the panel with which you are watching the test screens, better the blacks, and the Glow will appear.

I"m recording test screens mostly on an OLED viewfinder so that blacks and the amount of glow will appear when watching with a TN panel, better than in person or on an OLED screen. For the most realistic black level and IPS Glow picture you should watch one of my reviews on an OLED screen or a good VA panel with a strong contrast - So my reviews are more future proof.

I had quite a lot of IPS panels and I think I can determine how much IPS Glow in a monitor as usual. Please consider, we are now talking about high refresh rate gaming monitors, while these monitors are using IPS panels from the manufacturer AU-Optronics. These panels have a brownish or bluish glow, depending on the individual unit.

60Hz LG IPS panels mostly have a greyish glow which is mostly less visible than this bluish and brownish glow within high refresh rate gaming monitors. But they also have a worse contrast ratio what makes the glow even less noticeable. Why? Imagine a black and a dark grey background, on which you will observe more amount of IPS Glow? The difference on the monitor with better blacks will show the IPS Glow more than a monitor with worse blacks.

Monitor adjustments also are very important when using an IPS panel in a darker environment or in a pitch black room. Ensure that you set proper height AND tilt adjustments. While individual units differ, you can easily find out easily which height and tilt settings are the best for your monitor when opening the test video and darken the ambient light.

This one is probably a myth but I simply want to mention this since several people on different forums swearing that this one can help. Simply take a microfiber cloth and massage your panel (edges) for around 20-30 Minutes. In my case, it did not help on around 10 monitors - So I gave it up.

Yes, you actually will get a smaller panel size when increasing the distance to the panel but if the IPS Glow bothers you a lot, you should simply try it out. If you cannot increase the distance further, you can try to wall-mount the monitor or simply lean back in your chair. I do recommend a distance around 80-120 cm. The farther the less visible the Glow of course.

This part is a bit tricky and you should be very carefully, especially with credit cards. DO NOT use credit cards to lose the panel frame simply because of two reasons:

Even if you will lose the inner panel frame out of metal a bit, the outer panel frame (mostly made out of plastic) will again push the inner panel against the panel.

While the inner panel frame is out of medal and also have a bit sharper edges, in the worst case your credit card can lose some plastic pieces which will be stuck in the inner panel frame. The result out from this is that these plastic pieces will cause more panel pressure and more Backlight Bleed.

Different units from different manufacturers will have different constructions and closing mechanisms so that you have to figure out how to open your monitor model. In my case, with the Viewsonic XG2703-GS, removing the panel frame only helped a tiny bit in terms of Backlight Bleeding. Losing the inner panel frame is not really possible and even when I was able to increase the gap between the inner panel frame and the display it also sometimes has increased the Backlight Bleed, probably because the backside of the inner panel frame became more tension.

If you cant stand the IPS Glow in any case OR if you just cannot get used to a lower brightness and you simply want to play in a pitch black room, an IPS panel is not suited for your needs. If you already got an IPS Panel then let us know if you have some other tips & tricks or if some of these tricks did help you. However, with some tricks we can already drastically reduce the perception of the amount of the IPS Glow and improve the overall image quality and dive into some awesome games (:

IPS (In-Plane Switching) monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals and the liquid crystal"s ability to shift horizontally creates better viewing angles. The creation of IPS monitors was to provide a solution for the limitations found in TN (Twisted Nematic) monitors.

As a result, you can see different colors at the corners of the screen from each angle when it displays dark patterns. Compared to light leakage, this effect is a natural phenomenon on IPS panels.

Poorly designed backlight. LED-backlit LCD monitors require a backlight to show the image on the screen. The position and quality of these backlight systems have an impact on the uniformity of the screen. Many monitors only have a strip of LEDs at the top or bottom of the screen and use a series of diffusion films behind the LCD panel to create an even backlight. Unfortunately, not all of these designs are made the same, and edge-type backlights will often have a visible backlight that looks like a distracting bright strip on one of the edges of the screen. However, some higher-end monitors have direct LED backlighting with LEDs placed all over the screen, resulting in better uniformity. Learn more about different types of backlights on TVs here.

Lenient manufacturing and uneven frames. LCD screens are made of many layers, and most of these are flexible. When the monitor is being built or transported, some of these layers likely bend. These can cause uneven diffusion of light which leads to clouding and backlight bleed.

Monitors use different panel technologies to produce an image. Most monitors use LCD panels, of which there are different types. VA panels are known for their high contrast ratio, so they display deep blacks, but it doesn"t mean they have good black uniformity, as seen with the AOC CQ27G2 in the When It Matters section. The more common IPS panels have a low contrast ratio, which we can see with the ASUS TUF Gaming VG27AQL1A above. On average, VA and IPS panels have about the same black uniformity, but it depends on the model. There"s also a rare third panel type, the TN panel. It usually has the worse uniformity, as you can see here.

There"s another panel technology that"s different from LED-backlit monitors: OLED. These types of displays don"t have a backlight and use self-emitting pixels to display an image. Because of this, they have perfect black uniformity with no blooming around bright objects as they can turn off individual pixels. These monitors get a perfect score of ten for our black uniformity, but there are only a handful of OLED monitors we"ve tested, as they"re more common with TVs. Below you can see what an OLED looks like compared to an LED monitor.

IPS glow refers to a specific type of uniformity issue that, as the name suggests, is most common with IPS-type LCD monitors. Unlike normal uniformity issues, the cause for IPS glow is mostly the screen"s vertical viewing angle, which is why it often appears at the corners.

In a normal viewing position with your eyes being level with the center of the screen, the corners of your monitor are at a much steeper angle than the central areas. These areas of the screen can start to show the artifacts that appear when using your monitor beyond its viewing angle. Colors and brightness shift, and parts of the screen with very slight backlight bleed appear to worsen.

Unfortunately, you can"t do much to mitigate IPS glow except adjust your viewing position. The way to make sure the IPS glow is caused by the vertical viewing angles and not backlight bleed is by shifting your point of view. As you go up and down the screen, if you notice the edges further away from your eyes start to shift color, then this is the IPS glow.

You can sometimes reduce backlight bleed caused by the outside frame of your monitor sitting unevenly. If your monitor has rear-accessible screws to disassemble the frame, you can try tightening or loosening them. It can have a very strong impact, so be careful with your adjustments, as it also can make the issue worse.

We test for the black uniformity on a monitor to see how well it displays a bright object on a dark screen. This test is important if you tend to use your monitor in a dark environment, especially when viewing content with dark scenes, like video games or movies. A monitor with bad black uniformity can get distracting. We take a photo and measure the standard deviation of the black uniformity, both with the local dimming feature enabled and disabled. A monitor"s panel technology impacts the black uniformity, but it varies between units, so no two monitors are alike.

Backlight bleed test is way to check if your display has backlight bleeding problem. Backlight bleeding is a display defect where you can see bright portions near the edges or corners of the screen. It causes uneven brightness and distorted picture quality. It is a permanent issue and requires buying a new monitor if there’s a lot of backlight bleed.

While backlight bleeding is a problem that can occur in any type of display, IPS Glow is limited to the IPS panel displays. It causes bright lights visible at the corners of the screen specifically.

IPS glow can be fixed by adjusting the brightness settings alongwith ambient lighting. On the other hand, backlight bleed is a permanent problem and cannot be fixed. The only option is to buy a new display monitor.

Backlight bleeding is caused by wrongly aligned superimposed layers inside the IPS panel. This misailgnment causes uneven pressure that displaces the liquid crystals allowing the backlight to ‘bleed’ through the spaces and reach the viewer.

Backlight bleed becomes a problem when it starts disturbing the viewing experience. Most monitors with backlight are vulnerable to this issue but it can be tolerated only to an extent after which you must replace your monitor.

Backlight bleed is permanent in most cases. It only goes away if it is a new monitor as the layer pressure decreases a little after use. If you have backlight bleed for over a few months, it is more likely to stay as it is.

Depending upon the severeness of bleed, the brand, and the time of purchase, backlight bleed can be claimed under warranty and your display is eligible for replacement.
