lcd panel has a line accross it brands

TV screen lines are an irritating occurrence, and many different issues with the TV can cause them. This article will go over what causes this, whether or not you can fix it depending on the cause, and how to fix it.

When any part of a TV"s display gets damaged, corrupted, or is defective, it can cause lines to appear on the screen. Some TV parts that can cause horizontal lines to appear are the LCD panel, T-Con board, or row drivers.

Issues with these parts can happen for many reasons, and the way your lines appear can tell you a lot about what"s wrong. If the lines are new, one of these parts was likely damaged.

If you"re seeing colored horizontal lines, it may be because of the T-Con board. If other parts don"t seem to be an issue, this part of the TV could be causing the lines.

If lines appear on your TV, you"ll want to inspect the TV itself. You can fix some issues that cause lines to appear, but others may require a professional or a new TV altogether. Some of the most common causes of horizontal lines are:

LCD screen damage. The LCD provides your TV display with light. If you"re handy, you might be able to fix this by doing a little work with the insides of the TV, which you can read about below.

Other devices you"ve connected to the TV. They may also be having issues of their own or might not be compatible with your TV. In this case, you"ll have to inspect the device instead of the TV.

All these issues can be fixed, though it ranges in difficulty. If you"re unsure how to repair your TV, you may want to get the TV professionally repaired.

Knock or tap on the back of your TV. If the issue is with cable connections, this could solve the problem. It could also indicate a problem with your T-Con board. It won"t fix the issue, and the lines may reappear, but it can give some insight into the problem. If it"s your T-Con board, you"ll want to have T-Con replaced.

Change your TV"s settings. This step might work for you if the issue isn"t because of damage. First, try switching the TV input from different HDMI ports or AV ports. Doing this can rule out problems with specific inputs.

Run a picture test on your TV. It"s a built-in feature on newer TV"s which allows you to see if the TV display is corrupted. Doing this may look different depending on your TV, but generally, you can go into the settings and find a support option or just a picture test option.

Take a look at the LCD screen. If it"s damaged, you may want to get the screen repaired or replaced. It may be a less costly option than buying a new TV altogether.

Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

The steps for fixing lines on your TV will also work to fix TV glitches like flicker and stutter. For example, check the cables and connectors and ensure there"s no issue with your input device.

If your TV screen looks blue, it could be faulty connections, a defective backlight, or incorrect color settings. Some LED TVs naturally have a blue tint, which you can offset by changing the color temperature.

To fix screen burn on a TV, adjust the brightness settings and enable pixel-shift. Sometimes playing a colorful video with fast-moving action for half an hour might help.

Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better.

So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.

Vertical and horizontal lines on the best desktop monitors can ruin the immersive effect from your display, which is especially frustrating if you’ve invested into your monitor, like one of the best curved gaming monitors. To find out how to fix annoying vertical lines or horizontal lines on an external monitor, you’ll first want to test the picture to find out what causes these lines on the computer monitor, whether the problem is from the PC, cable box or another input source, or if the fault is with the monitor, its LCD panel or internal hardware itself. And while on the topic of “vertical” lines, there are vertical monitors that exist to help make certain professions or hobbies more efficient, like coding and streaming.

Before attempting any other troubleshooting, such as fixing black bars on the side of your monitor, the first step toward finding solutions for this desktop monitor problem is to isolate the source of the issue.

The first option is to test out the image on your favorite computer screen without any peripherals connected. To do this, disconnect all cable connections and use the remote control or the control panel to disconnect Bluetooth and WiFi, if your external monitor is so equipped. If there are no vertical or horizontal lines on the default picture or menu screen, then the problem is likely due to your PC or input device, or to your cable connections. If the lines still appear, then the issue is likely to be with the external monitor itself.

If the monitor shows lines when not connected to any cables or input method, the problem is likely with the monitor itself. Image issues such as lines can be caused by damaged internal ribbon cables or the LCD panel itself. If this is the case, the repair process will depend on what the hardware problem is, whether you have a flat or curved computer monitor. If you see light leaking on the edges of your monitor screen, you may have blacklight bleed, which you can learn about in our resource content on what is blacklight bleed.

If the lines go away when your external monitor has no input, then you’ll want to look for a connection issue or an issue with your PC or laptop’s graphics drivers, driver settings, or picture settings. Additionally, you may want to check for any input lag issues with your monitor at this time.

Make sure all cables are connected securely. A loose connector can cause various picture issues including gray lines, pink lines or green lines.You may want to unplug your monitor from the input device and check the condition of the ports. You may be able to see if there are any bent or broken pins in the connectors of these input terminals. Double-check the cables if you have two monitors. If you need more organization in your space, consider the best dual monitor mount. Don’t use a paperclip or other metal object to try and clear out a VGA terminal.

If you find a damaged part, you can either consult a repair service or professional repair technician, or you might want to fix it yourself using an electronics repair kit. Use caution when removing ports, and always unplug a monitor before working on a repair.You may need to consult the owners manuals to see what types of repair tools will be needed.If the cable is faulty, the solution may be just to buy a replacement cable. That may be the best path if you need to immediately fix your monitor and can’t spend time researching and repairing the damaged part on your own, like if you use your monitor for work like a monitor for video editing.

Look for any video card drivers or graphics card driver that has a yellow exclamation mark or question mark. These common error notifications may mean your laptop or PC graphics drivers are out of date. Many graphics cards offer a driver updater tool. You can also consider buying a new, updated graphics card.

Alternatively, you can run a system scan to discover errors and graphics driver software issues. If there is a problem with your graphics card driver, it may show up on a system scan. Try booting up in safe mode or BIOS, if available; this will often show whether the display issue is a software problem or a hardware problem.

Warning: Try booting up in safe mode or BIOS, if available; this will often show whether the display issue is a software problem or a hardware problem

A screen resolution adjustment may also help. If the device picture settings are not compatible with the monitor’s native resolution, you may see errors such as lines on the screen. On a windows PC, setting a display resolution or refresh rate that is not supported can damage a monitor.This is more often a risk with older CRT monitors.

So, why there are green lines on a monitor? Well, several factors might be at play if the displays attached to your PC aren’t operating correctly. It’s conceivable that your adapter or cable connection is the problem. Change the cable if it doesn’t work. If nudging doesn’t work, try another.

Throughout this post, we’ll explain why green lines occur on your display and the best techniques to remedy them. The extra information will be invaluable in fixing all of your monitor’s green lining concerns. It’s time to delve in!

There are a variety of possible causes for horizontal green lines or vertical lines on your computer screen, from outdated video card drivers to damaged ribbon cables and improper video cable connections. To determine whether the problem is software or hardware, you may examine the BIOS settings.

When you see a green line on your computer screen, you should inspect your display for any faults, including all the connectors. There might be a problem with the cable causing the monitor’s color to lose signal.

It would help if you examined the possibility that your computer has been infected with a virus or other malicious software. While this isn’t one of the most prevalent reasons for a green vertical line on the display, it’s still possible.

Faulty graphics drivers might also cause problems with your monitor’s connection to the computer. However, although this is the most common symptom, it may also be seen in the form of green lines on a monitor.

Because Windows 10 does not contain the BIOS, any horizontal or vertical striations on your display problem result from a software problem. If you don’t see any horizontal or vertical lines on your Windows 10 computer screen, this is likely a hardware problem.

It’s possible that your computer’s drivers don’t cause the flickering green lines on your display if they occur immediately after the computer has started up and not on the initial screen while the machine is starting up.

The status of “This device is operating well” indicates that the hardware failure has no problems connecting to Windows 10 once the procedures are completed.

You’ll get an error number and an explanation of the issue if the component isn’t operating correctly. The device has been deactivated and must be re-enabled to fix “error code 22,” for example.

You may also try downloading the drivers from the hardware manufacturer’s website if it doesn’t work. Make sure you’re looking at “Display adapters” (in this case, “NVIDIA GeForce 9800 GTX/9800 GTX+”) and the graphics card’s name.

This is the standard procedure to remove the green lines on the monitor, regardless of whether your motherboard is set to UEFI or a classic BIOS configuration:

It’s good to have a backup copy of all of your computer’s crucial data before you begin. Even if a BIOS update fails, the data on your hard drive is not at risk.

Making a copy of your BIOS is an excellent idea, too. Don’t miss this step if you have to perform it manually, even if it’s done automatically during an update.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

The second case is a well-known one. It will not install updates if you shut off your computer during Active Hours. For this reason, it is necessary to either modify Active Hours or manually install the application.

Monitoring a computer’s refresh rate can help identify and correct problems with graphics performance. The monitor’s refresh rate refers to how often the screen updates its image. A slow refresh rate can cause visual artifacts, such as green lines, on the screen.

Collectively, these lines indicate that the monitor is not keeping up with the latest graphics rendering instructions. This can lead to an overall degraded experience when using the computer.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

Knowing your screen resolution, even if you aren’t an engineer or a photographer. You can appreciate your multimedia activities better if you know what you have and what you can do. In Windows 10, you may verify your screen’s native resolution by following these steps:

The resolution may be changed by selecting a different option from the drop-down menu. You should only view content that is compatible with your computer’s capabilities.

If you purchase a new external monitor or video card, you may have to change your resolution. If you’re having problems with your monitor, the first thing you should do is check the resolution. It’s a straightforward solution to a variety of visual issues.

When you start Windows regularly, programs and services in the background may cause these conflicts. If you’re having trouble accessing Task Manager, we’ve got the answer.

The monitor cabinet should never be opened to service this item. Everything that hasn’t been stated explicitly in the user handbook should be avoided at all costs.

Do not connect the monitor to anything other than the designated power supply and HDMI cable, which should be clearly stated on the monitor label or backplate.

Ensure that the monitor is close to a working power supply. The monitor’s power cord may be yanked out of the socket with a rugged grip. Attempting to disconnect the display issue by pulling its cord will not work.

Be sure to switch off your display when not in use. A screen saver program and turning off the display when it’s not in use will significantly prolong the monitor’s life.

The cabinet’s design includes ventilation holes. These openings should not be obstructed in any way. You should never shove anything into a cabinet slot or any other aperture!

The green line of death seems to be caused by a hardware problem based on the current symptoms. If you go back in time, you may discover similar problems on non-Apple devices. This problem only appeared on OLED-display phones, to be more exact.

There may be more to the problem with water damage than just a replacement screen, but it’s typically just a matter of getting a new LCD or OLED display.

Language settings are not lost when a monitor is reset to factory settings. Your specific settings, such as contrast, brightness, and picture ratio, will need to be re-entered after a factory reset.

Due to obsolete GPU drivers, the green lines on a Windows 10 laptop are standard. Using specialist driver update tools, you may repair this problem. One of the most prevalent reasons for this issue is a malfunctioning laptop display.

Your phone’s LCD might be damaged if you don’t mend a cracked screen right away. Damage to the LCD screen might occur if dust penetrates the screen cracks. Your phone’s LCD screen might be damaged if you drop it in water or other liquid.

A faulty video connection is most likely to blame for a monitor with no signal. Connect your display and PC using a different VGA cable or ribbon cable to check whether the problem remains. If not, then your video cable is to blame for this problem. Try attaching your display to another computer to see if it helps.

That’s all about the green lines on the monitor from us. An external display with bothersome vertical lines or horizontal lines may be fixed by testing the image to determine what causes these lines on the computer monitor.

It doesn’t matter whether the computer, cable box, or any other input source is to blame; the monitor, its LCD screen, or internal hardware is to blame.

Don"t get me wrong, the speed of Dell"s response in sending out engineers, etc has been top notch, but the quality control on the other hand leaves something to be desired.

This particular LCD issue arose before in 2006, affecting various Laptop manufacturers, including Dell, but particularly affecting Apple. The defect presented in the same way but the affected panels that year were all Samsung screens, a specific model number. Affected customers found that using an LG panel as a replacement solved everything. Now it looks like it"s the other way around.

This to me suggests that one particular method of manufacturing LCD screens results in this sub-par quality, but must be cheaper to do. Many people with imperfect vision won"t even notice the problem, and if it saves the manufacturer a handful of dollars per panel, they can handle the small volume of returns and still be better off than if they"d built the screens to spec in the first place.

Dell assure me there are no other brands of LCD panel used in the Vostro so it looks like there"s no resolution to this and anyone who wants a 15.4 WUXGA screen should be looking elsewhere.

I"m currently debating whether to negotiate the return of the screen upgrade fee or simply to reject the laptop altogether, and buy a laptop with a decent screen instead. It"s a shame that 15.4 wuxga offerings are so thin on the ground from other manufacturers, but an even bigger shame that I might now be forced to buy something other than a Dell, whose computers I have repeatedly bought and recommended in preference to other brands, partially because of the good service (and all through this the service has been excellent bar the mainboard/keyboard issue) and partially because of the solid quality.

I like the vostro, I just wish Dell hadn"t taken the decision to cut costs with this bargain-basement substandard LCD screen panel - it ruins an otherwise very nice machine.

I’m a TV enthusiast, and I know the feeling. The pesky rolling bars can get on your nerves because they make it hard to focus on what you’re watching.

There is nothing to worry about though, your TV isn’t dead yet. The annoying lines can be due to loose connections, poor signals, outdated software, or internal problems.

To rule out this possibility, ensure the cables connecting the device to your TV are in perfect shape and securely connected. Test your TV with another video input to confirm this.

Disconnect all devices from the TV. Let each device boot up, then plug them back in one at a time. Take notice if any of the devices cause the horizontal lines to reappear.

Another common cause of horizontal lines on a TV is interference from other electronic devices. EM interference occurs when two devices with different electrical properties are in proximity to one another.

Most modern TVs feature anti-interference technology to prevent interference from nearby devices such as wireless routers and microwaves. The screen may display those annoying horizontal lines if this technology isn’t working correctly.

You could also have horizontal lines on your TV from other devices in your neighbourhood. EMI is particularly common in apartments with many electric appliances.

Faulty and loose connections are the most common cause of horizontal lines on a TV. If you recently moved your TV, you might not have properly connected the cables.

Poor signal quality from cable or satellite services could result in rolling horizontal lines. The problem is more likely to occur when watching standard-definition channels over high-definition ones.

You can check the TV signal quality from your receiver or box by connecting another device directly to your TV. If there are no horizontal lines on the screen when using another device, it’s likely that the box or receiver has a poor signal.

A damp screen causes moisture to build up behind the glass of your television, causing image distortion. You should clean or dry your TV as soon as possible after noticing these issues to prevent further damage.

If you live in a place with high humidity, you may have a problem with condensation on the screen. This can occur when using your TV in an environment that’s too warm, such as an enclosed room or cupboard without proper ventilation.

The solution to this problem is straightforward. Wipe your TV screen with a soft cloth to remove all dust and dirt. And if possible, watch your TV in a well-ventilated room.

Damaged liquid crystal displays (LCDs) can cause horizontal lines on your TV screen. These lines may appear as one continuous line or as multiple lines equally spaced apart.

Vibrations, heat, and voltage surges can damage LCD screens. To fix these horizontal lines on your TV, you will need to replace the damaged LCD screen.

If you are handy, consider re-soldering any faulty connections to prevent any damage to other parts. However, if your warranty is still valid, doing this will void it. I would advise that you only do this when your warranty has expired.

A row driver circuit sends signals from the microprocessor to each pixel row on the display panel within an LCD panel. When one or more pixels in a row go bad, it can cause lines across your screen. To fix this, you will need to replace the failed row driver.

Most manufacturers list common issues and their solutions in the manual. If you don’t have your copy of the user manual, you can most likely download it over the internet.

Turn off the TV, unplug all cables, and wait 30 seconds. Next, plug in the power cable and turn it back on. If this does not work, proceed with the next step.

Hitting the back of the TV with the palm of your hand helps to dislodge dirt. Hits can also help restore loose connections, though this is only a temporary solution.

Give your TV a few smacks while checking if the horizontal lines disappear. However, do not hit it hard as you could end up damaging it instead of resolving the lines.

Ensure all the cables and wires connecting your TV to other devices are in good shape. Connect each cable and wire securely and replace worn-out cables and antennas.

Connect your satellite or cable box directly to the wall socket instead of a splitter or power strip. Connect any loose or disconnected wires and then try watching TV.

If the lines are still there, disconnect and reconnect everything again and see if your picture improves. If the rolling lines do not disappear, move on to the next step.

This is especially important if you’ve recently moved or transported your set. Screws can loosen over time or during transport, so make sure to double-check them.

Go to the manufacturer’s website and download the latest firmware version. You can perform the update by connecting a USB drive to your computer and running the software.

Connect your TV to a Wi-Fi or Ethernet network. Connect it to Wi-Fi or Ethernet with a strong signal if you have a smart TV. Update your television’s software by going to Settings > System > Software Update > Network Update > Download Now. The update should resolve any issues caused by outdated software running on your device’s hardware components.

Static electricity can also produce moving horizontal lines on a television screen. It interferes with the way cable boxes and satellite dishes process signals.

Increase the frequency of image refresh on your TV by pressing the up button on your remote control. Or press the down arrow button to reduce the refresh rate.

Please note that these steps may vary across brands. That said, the above steps will apply to most Android TVs. If you have a Samsung or Sony Bravia, below are the steps to follow:

Detach the back cover of your TV by unscrewing all screws holding it in place. Use a screwdriver that fits precisely into each screw head to prevent the screws from being stripped

Keep in mind however that these steps may vary depending on the brand of TV you own. Be sure to check what the user manual says or contact customer support for further guidance.

Do not worry if you are not comfortable working with electrical equipment or do not want to risk damaging your TV. We recommend hiring a professional service to help you diagnose and replace a faulty T-Con Board.

If you have tried every tip above and nothing seems to fix the problem, then you’ll need to factory reset your TV. Resetting it will restore its original settings and should fix any glitches.

First, turn off your TV and unplug it from the wall socket. Wait for at least 10 seconds before plugging it back in and turning it on again. This will reset the power supply to the device.

Next, press and hold the power button on the remote control until the TV turns off again. Release the remote’s power button and wait a few seconds before pressing it again, only once, to restart your TV.

Now that you’ve restarted your TV, perform a factory reset by following these steps: These steps may vary depending on the TV’s brand. If you have a Sony Bravia TV for instance,

Contact customer support if you have ruled out external factors causing the horizontal lines on your TV, and they’re still there. The company will ‌help you identify the problem and offer a solution.

Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.

HP recommends that you only order parts from an authorized HP repair parts dealer. Parts ordered from third-party companies might not perform as expected and might cause additional

Due to the fact that the issue is isolated to a single line (even with multiple pixels in height) it"s unlikely it"s the actual signal (e.g. cable or connector pins).

Some issue with the connection would most likely screw up several lines and/or the whole image and it won"t be isolated to exactly one line (especially with digital connections).

In a similar way, issues with the graphics card should most likely cause issues with the whole screen (like garbage/random patterns). Those shouldn"t be isolated to a single line.

Turn off the monitor, disconnect all cables, and put it flat on your table (screen up) so it"s sitting plane on the table. Let it sit there for a night, then try again.

If everything else fails, what happens if you use your finger nail and pull it over the faulty line? Don"t push too hard, just so there"s some pressure (typically shows some short colored trail that should disappear within 1-2 seconds). Can you see any additional patterns or "waves" that don"t fit to what you see in other areas of the screen?

Please note that these steps may vary across brands. That said, the above steps will apply to most Android TVs. If you have a Samsung or Sony Bravia, below are the steps to follow:

Detach the back cover of your TV by unscrewing all screws holding it in place. Use a screwdriver that fits precisely into each screw head to prevent the screws from being stripped

Keep in mind however that these steps may vary depending on the brand of TV you own. Be sure to check what the user manual says or contact customer support for further guidance.

Do not worry if you are not comfortable working with electrical equipment or do not want to risk damaging your TV. We recommend hiring a professional service to help you diagnose and replace a faulty T-Con Board.

If you have tried every tip above and nothing seems to fix the problem, then you’ll need to factory reset your TV. Resetting it will restore its original settings and should fix any glitches.

First, turn off your TV and unplug it from the wall socket. Wait for at least 10 seconds before plugging it back in and turning it on again. This will reset the power supply to the device.

Next, press and hold the power button on the remote control until the TV turns off again. Release the remote’s power button and wait a few seconds before pressing it again, only once, to restart your TV.

Now that you’ve restarted your TV, perform a factory reset by following these steps: These steps may vary depending on the TV’s brand. If you have a Sony Bravia TV for instance,

Contact customer support if you have ruled out external factors causing the horizontal lines on your TV, and they’re still there. The company will ‌help you identify the problem and offer a solution.

If you usually watch TV alone from directly in front, you most likely don"t need a wide viewing angle. You should just turn the television to face you directly. However, if you watch TV with multiple people in a wide seating arrangement, you should benefit from wide viewing angles as those viewing off-center still see an accurate image.

Also, viewing angles have an effect if you sit very close, and in particular if you use the screen as a computer monitor. If you sit too close to the screen of a TV with narrow viewing angles, the edges of the screen might look darker and washed out. If it has wide viewing angles, however, the image remains accurate no matter where you sit.

There are a few competing TV technologies and panel types that each present their advantages and disadvantages regarding viewing angles. For LED-backlit LCD TVs, the LCD panel technology used is a big determining factor for how well a TV retains picture quality at an angle. There are two main types used in TVs: IPS and VA, and the differences between each panel type are noticeable; you can learn more about them here.

IPS panels are superior to VA panels when it comes to viewing angles. They"re generally recommended for wide seating arrangements because the image remains accurate when viewing from the side. On the other hand, the image on a VA panel quickly loses accuracy as you move off-center, and it can get pretty noticeable when sitting at a wide angle. This doesn"t mean IPS panels are perfect, however, as they have a lower contrast ratio than VA panels, so choosing one type over the other is a trade-off between viewing angles and contrast.

OLED is a different technology that uses self-emissive pixels. Each pixel turns itself on and off and emits light in all directions. This means that OLEDs have very wide viewing angles, even better than IPS panels, and they also have a near-infinite contrast ratio.

To improve viewing angles on VA panel TVs, companies have introduced viewing angle technology, like Samsung"s "Ultra Viewing Angle" and Sony"s "X-Wide Angle". This improves the viewing angles a bit at the cost of its contrast, but the contrast still isn"t as low as IPS panels. These TVs meet a common ground between viewing angles and contrast, without a decrease in overall picture quality. Samsung and Sony are the only two major manufacturers that have introduced such technology, and they"re generally only available on higher-end models.

How long will your LED display last? In nearly every industry, from retail businesses to concert halls to corporate centers, decision makers need to evaluate the return on investment (ROI) of their LED signage. In most cases, potential buyers go straight to the obvious place: the LED manufacturer’s spec sheet. The industry standard for LED lifespan is 100,000 hours, or about 10 years, and most people assume that’s how long their display will last. But it’s not quite that simple.

The 100,000-hour figure assumes that every diode will be running at full brightness, consistently — which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display’s lifespan; you can’t rely solely on the number on the diode spec sheet.

“The reality is, your screen can often last significantly longer than 100,000 hours,” says Kevin Izatt, a senior product manager in Samsung’s Display division. “We’ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.”

The biggest contributor to diode degradation is heat. As you increase a diode’s brightness, it produces more heat. Your display’s physical environment also contributes to the temperature of the diodes, especially for outdoor displays.

“Let’s say you’re in Vegas — Death Valley. The diode is fine to operate at those temperatures, but it will degrade faster,” says Izatt. “Temperature is a big factor — and not one you have control over.”

The quality of your display’s power supply — and how hard it drives the diodes — can have a significant impact on your screen’s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.

“Fans are mechanical; they break down,” explains Izatt. “And similar to your computer, the electrical components don’t last forever. Together, these factors all contribute to the lifespan of an LED display. Looking at just the diode lifespan doesn’t give you the complete story — almost always, another part will go out first.”

“Something like airflow is very important,” says Izatt. “You need a screen that has good cooling, and a design that allows heat to flow out of the back through vents.”

It’s easy to see why: The circuit boards powering the display release heat, and that heat needs to go somewhere. Without a strong design, thermal stress will degrade the life of the display, except for the highest-quality parts — optimal conditions notwithstanding.

“Lots of variations on the color and brightness you use will impact the life of the diode,” explains Izatt. “For instance, black doesn’t use any of the diodes at all. And if your content is using lots of gray, that’s a much lower power output than white.”

That’s not to say you should hold back on displaying rich, vibrant colors — after all, that’s what LED does best. But it does factor into your product’s life expectancy.

To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.

Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.

You can’t rely on the number on the diode spec sheet; the lifespan of your LED display depends on many more factors. “Overall quality has a tremendous impact on the life of the display that diode specs just don’t take into account,” says Izatt. Your best bet is to look at the purchase holistically and invest in a top-tier product.
