Backlight bleeding is a common problem in LCD monitors and TVs. It’s usually not too much of a worry, but it can be if you notice it is severe. In this article, we’ll show you what backlight bleeding is and how to fix it.

Backlight bleeding is a common issue found in LCD screens when the backlight is to bright and leaks through the edges of the LCD and causes a blotchy look around the edges of the display. This light bleeds beyond the bezel of the display itself and can be very distracting. Many people have found that this issue is most noticeable on darker scenes of movies or games, where a single white or gray blotch in an otherwise black program or image can be quite noticeable.  The issue is generally caused by a failure in the LCD itself and cannot be fixed by a software or firmware update. The following steps should help to diagnose and fix any issues

Backlight glare is one of the problems you may have noticed with many LCD displays, be it TVs or gaming monitors. Depending on the type of game or activity you are playing on your screen, it can be very difficult to determine if what you are seeing is translucent.

Therefore, I am writing this article to help our readers and gamers who are experiencing similar problems to easily identify backlight discoloration and find answers to questions like this: What is backlight discoloration? What causes the backlight to go out? And how to check and fix a bleeding backlight. So let’s dive into our article.

What is bump lighting?

First, the backlight bleed is not normal. Simply put, backlight bleed occurs when the LCD’s backlight tubes do not fully overlap and light escapes from the edges of the screen, resulting in uneven light distribution.

These screens work by blocking out light that is not needed for visual display at any given time. However, when backlighting or flash bleeding occurs, the backlighting appears in the corners or larger areas of the screen and ruins the viewing experience.

Backlight fading is especially noticeable with LCDs, as they have a special backlight system, as mentioned at the beginning of this article. In most cases, a slight discoloration of the backlight of TVs and monitors can be expected due to the nature of the display technology. In most cases, backlight runaway is not easily diagnosed or not so severe that it cannot be tolerated.

The kind of problem we’re talking about in this article, and for which we’re looking for a solution, is all too obvious. If your manufacturer has a return policy and you still qualify, we encourage you to make a return or use the warranty. But if all this doesn’t work for you, let’s see what steps you can take if you notice a discolored backlight.

Message: We have found that some IPS users often confuse the backlight discoloration with the brightness of the IPS screen. While backlight dimming is a technical shortcoming, IPS glare is a configuration problem that can be easily corrected by changing the angle and distance from which you look at the screen and, in some cases, by lowering the brightness and increasing the ambient light.

What makes the backlight go dark?

Backlight leakage is a screen defect caused by the misalignment of multiple layers stacked at different angles used in IPS monitors. These deviations cause pressure in the screen, which changes the orientation of the liquid crystals in the IPS panels. Because of these shifts and deviations, the light penetrates more unusually in some places than in others.

Backlight activation modes

There are two main types of backlight fading. And if you’re experiencing this problem on your screen, it’s because it is:

  • Opacity is when irregular points of light appear all over the screen. You can easily see that the light on the back of the screen is concentrated in one area, while another area appears darker.
  • The flashlight, which is smaller and often less visible, is usually located in the corners of the screen. In this case, at the advanced stage, the edges/corners of the screen are brighter while the center of the screen remains darker.

To make sure you have exactly the right backlight bleed, it is always a good idea to do a backlight bleed test, especially if you are not a technical user.

At lightbleedtest.com you can perform a simple backlight bleed test for free. If the whole screen stays dark, everything is fine, but if one part of the screen leaks backlight, you have a problem with a backlight leak. So let’s get on with the corrections.

Correcting the lack of backlighting

  • Loosen the screws of the screen
  • Rotate the screen frame slightly
  • Apply electrical tape to the edges
  • Use a microfiber cloth for bleeding spots.
  • Setting the lighting
  • Change the display

Loosen the display screws – Repair the backlight leak i

If you screwed the panel on too tightly, that’s probably what caused the backlight to bleed. This is because the screen deforms when the panel is firmly attached. To solve the lost backlight problem, loosen the screws securing the frame, but not too far, so the screen doesn’t fall off. If this does not solve the backlight problem, try the following.

Turn the display frame slightly – remove the backlight ii

If the monitor screen is not placed correctly in the frame, too much light will penetrate the edges. Some users have found that the bleeding problem is solved by checking that the screen is correctly positioned in the frame – and correcting it if it is not.

Tape around the edges – this prevents glare iii

If the backlight extends beyond the edges of the LCD, the frame may be defective or loose. The usual technique we use to replace the hose can also be used here. We recommend that you take electrical tape and tape the edges in a circle with it. This is the recommended solution if the problem is related to the screen frame.

Use a microfiber cloth for bleeding areas – Correct minor IV bleeding

It is also possible that the glow of the backlight is caused by grease, dust and liquids, so try to clean the screen with a microfiber cloth. Gently rub a microfiber cloth in circular motions over the bleeding areas. Try to apply moderate pressure to avoid damaging the screen.

After you clean the screen, you can turn off the monitor for a few days to let the screen stabilize and see if there are any changes.

Modification of lighting – back-lighting M

If you are playing in a dark room, a quick way to make the backlight reflection less noticeable is to use the monitor in a lighted room. If your screen is bright, a quick way to fix the backlight problem is to reduce the screen brightness. In both cases, make sure that the reflection of the backlight is not visible.

Display replacement – backlight wear removal VI

If none of these options work, the last option that does not require the purchase of a new monitor is to replace the screen. Replacing the monitor screen is not too difficult if you bought the right screen from the manufacturer. Many manufacturers send step-by-step instructions to help you replace the screen.

Frequently Asked Questions

What is the cause of backlight bleeding?

When you see annoying backlight bleeding coming from the edges of the screen on a new TV or monitor, don’t panic. It is a common problem with LCD screens. While it is not exactly a manufacturer defect, it is also not very desirable. Fortunately, if you take the time to research the causes of backlight bleeding and how to fix it, the problem can be fixed quickly and easily. If you own a phone or a tablet that has an LCD screen, chances are you have seen those small dots that seem to have a life of their own. They are backlight bleeding, the result of a gap that would normally be closed by liquid crystals separating the rows of pixels in a display — or the backlight that powers them. This gap opens up the possibility of light leaking from one row of pixels to another, and in the worst case, it can be distracting enough to ruin the viewing experience.

How do you fix a backlight bleed?

Welcome to another installment of our series on how to fix common problems with your device! Last time, we showed you how to fix an unresponsive phone screen . This time, we’ll be looking at an ailment that’s somewhat more common—a backlight bleed. LCD screens are made up of grids of individual pixels, and these pixels are responsible for displaying everything you see on your screen. The backlight is the light that shines through these pixels, illuminating them and creating the images you see. Unfortunately, backlight bleed is a common issue with LCD screens, and it causes parts of the screen to appear brighter than they should, especially around the edges and corners.

How do I fix the backlight on my TV?

Is your TV suffering from backlight bleed? You’re not alone. One of the most common underlying problems with flat-screen TVs is a condition called backlight bleed (also known as backlight bleeding, backlight seepage, or clouding) that manifests as blotchy patches on the screen, usually near the top or sides. If you’re experiencing this, don’t worry. You aren’t alone and the condition isn’t permanent. This blog is not only about providing a service and being professional, but also having fun. The following are a few blogs where some of my students having a little bit of fun. The backlight of a TV is a panel of light that shines from the TV’s rear, towards the viewer. In theory, it should evenly illuminate the TV’s screen and make the colors, contrast, and overall viewing experience more enjoyable. When the backlight is not evenly distributed, however, the image on the TV screen is patchy and distorted. This is called backlight bleed, and it’s a common problem for flat panel TVs.
