line down lcd screen supplier
Vertical lines appearing on LCD screen is very common. Whether the screen belongs to a laptop computer or desktop PC, mobile phone, or even a television, the fault is usually due to the ribbon cable and its connections.
A faulty ribbon cable can cause all sorts of havoc manifesting in bright vertical lines. Sometimes they can be coloured lines such as blue, green, grey, black, and red. The lines can appear thick or thin and on just one-half of the screen. Sometimes the fault will manifest as two vertical white lines. You can even get horizontal lines as well.
If you have lines appearing on the LCD screen, then the first simple thing to check is the seating of the ribbon cable that connects the display panel to the motherboard. Most of the time, the fault is with the poor connection made by the ribbon cable.
One of the most common problems with ribbon cables is oxidation of the contacts. It can happen either on the ribbon cable contacts or on the socket contacts. Manufacturers often use a mix of gold and copper for the electrical contacts, however, if they have not used enough gold, then oxidation occurs over time. This results in a working television or laptop screen suddenly exhibiting lines.
One of the most common faults with laptops is that the ribbon cable connecting to the LCD panel cracks. It typically fails near the hinge area due to flexing in that region, and over time, some of the tracks on the plastic cable breaks. I have seen these types of faults on many laptops. It does not matter whether it is a Lenovo, IBM, Acer, Samsung, Toshiba, or even a MacBook Pro!
This type of fault can also occur on LCD televisions; however, it tends to be on new units, where the box has received an impact during transit from the factory.
I used this same method of troubleshooting to repair an LCD television recently. Modern televisions have a video out socket, and if you feed the signal from that to another monitor, you can check for the quality of the video display. If the external monitor does not show lines, then you know for sure that it is a connection issue. Hence, this method of troubleshooting works for some of the modern televisions as well.
When half of the vertical interlace is missing showing a picture that is broken up vertically, the display appears with vertical lines. This is usually due to a cracked ribbon cable.
Generally, for laptops a replacement cable is always required due to it breaking near the hinge. I had this Dell laptop and replacing the LCD ribbon cable solved the problem. I managed to buy a replacement from Dell for a modest price £6.00. The laptop was just outside the warranty period; however, they still shipped out the cable free of charge. This is the reason why people buy Dell. In my experience Dell tend to stand by their customers and products, and their prices for replacement parts are realistic and down to earth.
LCD display screens on notebooks, monitors and TVs alike are made up of two thin layers of glass containing liquid crystal material between them. When the glass becomes damaged, debris infiltrates the crystal layer or another issue occurs with the display function, this causes vertical lines of color to appear when the monitor is fully illuminated. These lines are either permanent due to internal failure or temporary due to faulty display connections.
Diagonal, jagged and both horizontal and vertical lines typically indicate panel damage. A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color.
If the lines are infrequent in their appearance, or are not permanently visible, a loose video cable is often the problem. As devices are carried, dropped and bumped, cables become loose even in laptops. Laptops are built with casing to absorb and dissipate small shocks, but even some bumps can cause cables to become loose. Even televisions and monitors, while often stationary, can still have loose cables if not properly seated.
If you"ve ever opened your laptop to clean underneath the keyboard, you might see numerous things like food particles, hair or even dust. On the rear of monitors and televisions, they also contain a series of holes or slits that dust can creep into the inner workings and cause problems. Regularly cleaning out a laptop"s keyboard and dusting off the rear of a monitor or television can greatly extend its useful life. This is a preventative measure and rarely works in removing any existing lines on a screen.
The first step in troubleshooting is determining the extent of the damage. For external monitors or televisions, re-seat any video input cables or consider replacing the cables with new ones. Should the lines continue to display, this indicates an internal failure, something few consumers are able to fix on their own. Instructions exist online for individual products to disassemble a monitor, laptop or television to replace broken parts, but the most suggested course of action is shipping it to the manufacturer for a warranty repair. If no warranty is active for the device, consumers are then advised to replace the device entirely with a new one, as this is usually the cheapest solution. Lines on an LCD panel indicate the LCD screen or screen ribbon cable need to be replaced, parts that can cost several hundred dollars.

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 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.”
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.
As you plan your LED signage rollout — or an upgrade — learn how to configure and tailor your screens’ real-time messaging with an integrated CMS in thisfree guide. And if you haven’t decided what kind of display is best suited to your current project, compare all ofSamsung’s LED displays.
Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.
The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.
Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.
Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.
One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.
This problem occurs because of a hardware limitation that is known as "tearing." Tearing is a video artifact in which the top portion of the screen shows a different frame of video than the bottom portion. This is more noticeable during scenes that contain fast motion. There may be a noticeable horizontal line at the point where the two frames meet.
If you experience noticeable cut lines or tearing, and not only when you play a DVD movie, the display may be configured to a refresh rate that one of your monitors does not support. If this is the case, you can resolve the issue by configuring the display to a refresh rate that is supported by all monitors.
Back in April last year, Lionel blogged about a vertical line issue that could potentially affect customers who own 17" Inspiron 9200, 9300, and XPS Gen 2 notebook LCDs.
After engaging our engineering and product group teams, as well as the LCD manufacturer, to investigate and isolate the cause of this issue, we narrowed the problem down to a specific part within a certain date range. During that research, we found that the part may also affect the Inspiron 6000, 8600, Latitude D800, D810, and Precision Mobile Workstation M60 and M70 LCDs. That led to Lionel"s second blog post on the topic.
We"ve taken steps to contact those who may be affected to offer a warranty replacement and also put in place measures to rectify any out of pocket expense incurred by out of warranty customers who replaced the affected screens in the past.
That said, there are other variables that can lead to vertical and horizontal lines on other system types regardless of size or model. Lines on an LCD can appear sporadically, at random places on the screen, and for what appears to be for no reason at all. These lines can be caused by normal LCD failures brought on by a multitude of variables, which I"ll try to cover here. Vertical lines tend to be a more common issue in notebooks, primarily because they are subjected to more wear and tear on a daily basis than a desktop LCD.
The most common cause of these lines is simply a loose connection. As notebook systems are carried around, no matter how careful we try to be, they have a tendency to be bumped, jarred, and even sometimes the heart stopping drop. Though today"s notebooks are designed to better absorb and dissipate small shocks, it can still have adverse affects on the notebook"s internal components. A good bump or series of bumps and random movements can cause the LCD cable to become loose. The connection remains intact, but some breaks in the signal can lead to impurities in the reproduction of the image on the screen. Think of a loosely-fastened garden hose… water will still be directed and outputted through the end of the hose, but some water is lost at the connection. This is easily fixed by tightening the hose. Similarly, the LCD can usually be fixed by simply making sure the connection is secure. (Service manuals for Dell systems can be found here on support.dell.com.)
If these simple fixes don"t seem to work, then we need to look at the actual failure possibilities. Vertical or horizontal lines that don"t disappear after the basic troubleshooting are usually caused by circumstantial failures. The most common type of failure that leads to lines on the display is an open circuit connection between the driver IC (flexible circuit board) and LCD glass. This is usually caused by external stresses (mechanical, thermal, etc…), which causes the flex circuit to detach from the glass. The variables leading to the detachment are wide and are dependant on individual cases. With the amount of travel and various operating environments of a notebook, pinpointing the exact cause can be near impossible, unless of course the problem immediately follows a catastrophic event such as dropping the notebook or prolonged exposure to heat or cold, such as leaving the system in a car.
Investigations into technical problems, including which systems, batches, and date ranges are affected, are rigorous, and we strive for accuracy. Unfortunately, not every technical problem can be traced down to the root cause. But in every case, we try to proceed appropriately and in all fairness to affected customers.
If you are experiencing any problem with lines on your LCD and your system is not one of the potentially affected units, or in the date range outlined in Lionel"s earlier posts, please contact technical support to troubleshoot and identify possible fixes. See below for details on how to do that.
For example, it could signal that the power supply is either failing or faulty. In other cases, it could mean you have not connected the HDMI cable well, or there is a poor connection between the processing board and the panel. But another cause could be the picture does not fit the screen exactly.
When you see black vertical lines on your TV screen, the first step is to identify the primary cause of the problem. Start by testing the picture, check your cable connections, and verify that your external devices are working well.
You can also try changing channels to determine whether the lines appear on all channels. Understand that lines on a TV screen can either be a hardware or software issue.
Ideally, aspect ratio, screen resolution, and horizontal or vertical scan frequencies are settings that affect picture display on most TVs. In this case, refer to the external device’s user manual to adjust the picture format settings.
Your TV software runs the device. An outdated software program can cause many problems like vertical lines, poor picture quality, or failure to install apps.
In some cases, a TV fails to process a combination of image settings you have provided. That can cause many picture errors, including flickering lines on TV. While you can go through all the settings one by one, consider resetting your device.
Sometimes vertical lines on an LCD display could mean a damaged T-Con board. The T-Con or timing control card controls the timing of pixels displayed on the screen. If your T-Con board is faulty, the only solution is to repair or replace it.
If you see Samsung TV vertical black lines on the screen, check whether the lines are permanent or moving. If they are moving, your input source is incorrect. Disconnect and reconnect the video cable or HDMI to check if it resolves the issue.
Thirdly, you may come across a problem with your Samsung Smart TV whereby colored lines appear on the edge of your TV screen. The lines may be black, white, or green along the top, bottom, or side of the screen.
The issue occurs when you have set the picture size of your TV to JustScan or Screen Fit. Samsung calls the lines an Overscan line. If your setting is JustScan, the picture resolution of specific programs will not fill the screen, thus causing the lines.
You can resolve the issue by setting the picture size on your Samsung TV to 16:9. The setting will extend the picture beyond the edges and eliminate the Overscan line.
You can fix a TV screen with lines in different ways. For example, you can change channels to see if the lines appear on all changes, change the input source, check cable connections, or power-cycle your device.
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.
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:
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.
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.
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 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.
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.
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.
Weird lines appearing all over the monitor display is nothing new. You might see plenty of them, or just one. They can be horizontal or vertical. Sometimes there are so much of them that you can barely see anything on the display. Other times it’s just one or two.
If you see vertical red lines on your monitor screen, usually there is no reason to panic. Most of the time it is due to some benign software issue that you can easily fix. Even if it’s a hardware issue, a trip to the computer repair technician should be enough.
Vertical red lines usually indicate an issue with your driver or other software. The best way to make sure it’s not a hardware issue is to enter BIOS settings. Since BIOS is not a part of your operating system it is also not a part of your computer software.
On the screen, you’ll see which key you have to press to enter the BIOS, you usually have to press F10, Del, or F2. This key may differ depending on the computer’s manufacturer. If you can’t find it on the screen, search for it on the internet.
If the red lines aren’t there anymore, the problem is in your software. However, if the lines are still there, it’s a hardware problem. That means that something is wrong with your monitor.
If the problem is related to the software, most of the time the driver is causing it. This usually happens if your computer and graphics card aren’t connected well enough. Also, it may mean that the driver is outdated or it can’t handle the screen resolutions.
The best way to move forward is to update your video drivers. To do this, you should:Right-click the Start button on the bottom, left-corner of the screen and then click Device Manager.
If the red lines remain, you should first try to remove the driver completely. To do this:Follow steps 1-3 from the previous guide, but select Uninstall Device instead of Update Drivers.
Note that this means you won’t have your video card drivers anymore. You’re going to need to download them again. That’s why it is good to write the name of your video card model.
If you have a desktop computer and a monitor, then a monitor or a loose or faulty HDMI cable could be causing the problem. The best way to check if your monitor or HDMI cable is to blame is to connect your computer to another working monitor and see if the red lines appear on it as well.
If they do, then the problem may be in the connecting cable or your graphics card. However, if the lines disappear, then you should replace the monitor.
You can also try to replace the ribbon cable. One goes to the port of your screen, and the other to the port in the motherboard. Usually, a malfunctioning or loose ribbon cable can mess up the monitor display.
Zebra lines or blue vertical stripes on a display is a common problem many users report afteriPhone screen replacement. Usually, it’s not caused by a defective screen, then what the culprit might be? Here are some possible causes and solutions.
Solutions:do not force the connectors together until you are sure they are properly lined up; do not bend the flex ribbons during testing and installation.
Reason:aside from a bad connection between flex ribbons and the logic board, ESD (Electro-Static Discharge) is another big cause of vertical lines. Too much ESD produced by either the product itself or by human during the test or installation.
Reason:possibly the IC on the display is damaged if both of the above methods don’t help. Check the part on the top left and right corners in particular. If there’s any damage, or one of them has been crushed or the IC has been damaged then your part is defective. You’ll have to replace the screen with a new one.
Lastly, be sure to use an extension flex to test the screen before reassembly to prevent unnecessarily folding of the flex ribbons, as well as to prevent damage to the fragile connectors.
The appearance of static or flickering horizontal lines on a computer screen can be frustrating and inconvenient, but there are many steps you can take to try to fix your problem. This guide will walk you through various checks and fixes you can perform on your computer and its monitor to find out why the lines are appearing and what to do to make them disappear.
Horizontal lines on a computer monitor can be caused by overheating or physical damage to the monitor and connecting cables. Conflicts between the screen and selected screen resolution and refresh rate settings can also cause line problems, as can out-of-date device drivers and operating systems.
Try a different monitor. If possible, try connecting to a different monitor or screen. It can help you determine if the lines are caused by your computer’s screen or the computer itself.
Check your monitor while it’s disconnected. Keep your monitor powered on, unplug it from your computer, and look for any flickering or lines on its screen while it’s disconnected. If you see any kind of distortion, this means that your monitor is damaged.
Close and reopen your laptop. Close your laptop’s screen, wait a few seconds, and reopen it again slowly. Look to see when the lines begin to appear on the screen as you open the laptop. If the lines only occur at a certain angle, the cause is likely damaged wiring.
Check the monitor connection. Ensure all of the cables are securely connected, and watch for any improvements in screen image quality while you’re inspecting the cables. If you notice the image improves or worsens while touching the connecting cable, it may need replacement.
Remove magnets and electronics. If you have other electronics or magnetic devices near your computer, screen, or the connecting cables, move them somewhere else as they may interfere with the connection and cause the lines.
Reset your monitor to its factory settings. If you’re using an external monitor or screen, use its built-in settings, not your computer’s settings, to reset it to its factory settings. You can usually access these settings via a physical Settings or Menu button on the computer monitor itself.
To fix coloration and distortion on a computer screen, power the monitor on and off, restart the computer, and make sure the cable between the monitor and computer is connected securely. If you"re using a CRT screen, try degaussing the monitor. You can also try adjusting your video card"s quality settings and experimenting with your monitor"s adjustment buttons.
To fix screen burn on a monitor, also called "ghosting," try turning off your display, ideally for at least 48 hours. Also, try setting your screensaver to an all-white image and letting it run for a few hours. You can also try using the JScreenFix tool, which fixes stuck pixels.
