LED LCD screens have been around for a while now, and the quality of the technology has improved dramatically. But, like with computers and cell phones, there is still a common issue with these screens, and it is called “backlight bleed”. Backlight bleed is when the backlight of the screen is too bright, causing the image to appear darker, or with a red tint to it, depending on where the device is positioned. This can lead to trouble-some issues such as:
LED backlight bleeding is a common problem with all forms of LED screens, LCD screens, and even some plasma displays, but it is not so common among LCD screens. It is more common on LED screens, since LED screens have a larger pixel array.
Backlight bleed is a problem you’ll run into when using LED or LCD displays. A bright backlight causes the screen to glow, and the glow can’t be removed entirely without making the screen brighter and more prone to burn-in. But what causes backlight bleed? How do you fix it? What is the best way to fix it? These are the questions we answer in this tutorial.
The words “backlight” and “bleed” imply a plethora of visual issues with your LCD. It occurs as a result of light seeping from the LCD’s edges and corners. Backlight bleeding is a common occurrence. Modern displays use a new technology known as “Flash lightning,” which causes light leakage. It’s the leakage that you should be concerned about if you’ve ever seen irritating white spots of light on your screen.
What causes backlight bleeding?
LEDs are used in the majority of contemporary screens. The odds of a concentrated white area on the screen when the LEDs bounce back are slim, although it does happen sometimes. The color projection aggravates the issue in some way. It’s also worth noting that LCDs utilize the light blocking technique, in which portions of the LCD are intentionally closed off in order to show the ideal picture. You may not be able to fully understand the whole procedure due to its complexity.
Backlight leaking occurs when the LCD and sensors at the back end are unable to effectively block the light. These days, you may get bezel LCDs that do their best to alleviate the issue. Keep in mind that you won’t be able to fully solve the issue. It will follow you for the rest of your life, but there are methods to reduce it, which we shall explain.
- Note that IPS Glow is a distinct issue that should not be confused with backlight leakage. Unlike light leaking, the IPS Glow issue may be solved simply adjusting the display’s tilt. Play about with the brightness and ambient lighting, and you’ll be OK.
- Warranty: It’s preferable to obtain an RMA via the LCD since you can’t always repair the issue. It sticks with you, therefore it’s best to buy something fresh, like an OLED LCD, which doesn’t have these problems.
How can I stop the backlight from bleeding?
There are a few things you can check into to fix the issue, but if all else fails, RMA. Right now, it is the best viable choice.
Pre-requisites:
- Screwdriver
- Cloth made of microfiber
Let’s get started without further ado!
Remove the frame by unscrewing it.
Unscrewing the frame is the most frequent method for removing blacklight leakage. Tight frames cause the display to be distorted in some way. To remove all of the bolts, use a portable screwdriver. Keep in mind that excessive force may harm the LED. As a result, take care before attempting to resolve the issue.
Getting rid of the contaminated areas
Another factor to consider is the LED’s non-flattened surface. It may be due to the buildup of dust and oil. You’ll need a microfiber cloth for this. Grab it and begin massaging it in a circular manner on the bleeding spot. Make sure the amount of force used is kept to a minimum. LED is vulnerable to vandalism, and you don’t have to kill it since you choked it unintentionally. Allow the solution to settle in for a few days. If you don’t notice any apparent improvements after a few days, you may need to repeat the procedure.
Twisting the frame of the display
Backlight bleed may be caused by the LED’s loosened frame. When the display frame is moved, it fails to block any more light. All you have to do now is lose the bolts once again. After you’ve unscrewed the fasteners, rotate the frame inside to reposition it. Repeat the procedure until the bleeding has stopped. If not, you’ll need to look at the following workaround.
Checking on the progress
You may not realize it, but the bleeding may have stopped to some degree. You may keep taking pictures after each step to see if there are any changes. There’s another way to figure out what’s causing the bleeding. Continue reading the article to find out.
Bleed test under blacklight
The test allows you to identify all of the white light spots on the screen. If you’re wondering how to do the test, utilize the blank screen provided below to identify the issue. Unfortunately, if this does not resolve the problem, you may need to apply another workaround for accurate diagnostics.

adjusting the brightness
You will most likely fail to do anything about the IPS backlight bleed at times. Although it isn’t a professional solution, you may still enjoy your last minutes with the LCD. The only thing you have to do is lower the LCD’s brightness settings. The technique reduces backlight leakage by decreasing the quantity of light falling on the unrestricted areas of the screen. If all else fails, this is the best answer you can find.
What are some of the additional issues you may encounter with an IPS panel LCD?
- IPS Glow: This is a frequent issue with IPS panels. You get the impression that the monitor/LCD is blazing brighter than it should be. The flashes of light pouring out of the screen may be seen from a few angles. All you have to do to solve the issue is adjust the screen from various angles, and you’re good to go. If you are a light-sensitive individual, the appearance of glow may induce seizures, therefore you should address it as soon as possible.
- Clouding is caused by backlight leakage that is uneven. It’s one of the most serious issues you may have with your LCD, much worse than the bleeding. Obtain an RMA for the LCD!
How can I prevent future backlight bleeding?
As long as the system utilizes active backlight methods for image projection, the problem will persist. The only way to prevent the issue is to spend a lot of money on OLED panels with organic sandwiching (cathode and anode). It’s a viable alternative since OLEDs don’t have these issues. It’s also true that OLED displays are costly. Before going to the checkout, you would need to save a significant amount of money.
Another option for resolving the issue is to utilize methods in action to set the backlight in minimum mode.
Finally, some ideas
The results may persuade you to purchase LCDs in the future, but it’s not a major shift. Bleeding is a common issue with LCDs, and it isn’t apparent unless you are light-sensitive. Because of the quality and cost of CRTs and OLEDs, they may not be a viable choice.
You may depend on the previously stated procedures to resolve the issue. You may also take pre-measurements before purchasing the LCD. Before you spend any money on it, have it properly diagnosed; this will spare you the trouble of trying to repair the bleeding yourself.
Hopefully, the tutorial has solved your issue!
What kinds of queries do consumers have?
Is there an issue with backlight bleeding?
Not at all. You may use the methods given by the professionals to attempt to solve the issue. Even if you don’t always succeed in addressing a possible answer, it’s worth a go.
How does backlight bleeding appear?
The bleeding is seen on the screen as bright dots. It occurs as a result of a loss of light limitation at particular areas of the screen. Backlight bleeding is present if there is any indication of clouding (large areas of white light).
What is the maximum amount of bleeding that may be tolerated?
At 100 percent brightness, a little backlight leaking is typical. Technology is unchangeable! This is how things operate, so accept it.
The Backlight Bleed, or Backlight Logo, is a defect found on most LED LCDs (including the G15). When the screen is off, the Backlight (a.k.a. LCD Backlight) light is still shining. As soon as the screen is turned on, the Backlight is no longer needed, and the light is drawn into the screen where it can create strange looking artifacts..
