Q: "Vertical lines on iPhone 11 screen!! This is what happen to my phone after I bought it 3 days. Several lines appeared on the screen suddenly. Any idea why it happens? Any other user facing the same problem with me?" – from an iPhone 11 user
There are always a large number of reports from users stating that they find vertical lines on iPhone screen. This is an old problem that has been existing since iPhone 4, and the color of the lines may vary from red, black, blue, or purple. It could result from physical damage and software problems. Anyway, to solve this problem, you should follow the 8 solutions below, so that you can get rid of the lines while reducing the cost of the repair to the minimum.
A force restart is similar to taking out the battery and putting it back on. It is going to completely shut down all the apps and programs running on your iPhone. Whenever you see there are lines across the screen, you can fix it easily by hard rebooting your iPhone. After the hard reboot, the lines on the screen may disappear. To hard restart your iPhone, follow the tutorial enclosed below.
iPhone 6 or former iPhones: Press the "Power" and "Home" button on your iPhone simultaneously for around 13 seconds. You will feel the vibration of the phone, then it will turn on.

It might seem ridiculous, but in some cases, iPhone screen lines vertical problem are caused by things as little as water drops or dust. These things can be difficult to notice when you have a screen protector on the screen. If the water drops or dust get stuck between the screen and the screen protector, it is natural that there will be vertical lines across the screen. Therefore, you might as well remove the screen protector, clean the screen with a cloth and see if the lines have gone.
Essentially, cycle charging means charging the battery to 100%, then using it until it drains to 0%. When the phone is charged to capacity again, the vertical lines might disappear.
It is also possible for vertical lines to appear on LCDs when LCD cables become disconnected from the logic board during sudden jolts or a fall. A slightly shifted iPhone screen does not necessarily mean it is damaged; it is just a slight shift.
It might be possible to remove the vertical lines by gently pushing the iPhone"s screen back into place to reconnect the cables with the logic board. Make sure that you do not apply too much pressure to the screen in order to prevent the screen from breaking further. The steps are as follows:

Screen burn, a term derived from old CRT (cathode-ray tube) technology — and the reason for a vast industry of decorative screen savers — describes the phenomenon of image retention, otherwise known as persistence, ghost images, blurred images, artifacts, or after-images that linger on your smartphone screen after the original image is long gone. These can mar screen readability and coloration over time and can diminish your smartphone experience.
On mobile devices, screen burn is identified most often on AMOLED or OLED screens, and even then, it’s pretty rare on newer smartphones. It happens when users leave an image on their screen for too long, causing the pixels to struggle when switching to a different color. This may happen more easily with blue colors, but can occur with any image that’s left on screen too long, especially in the brightest setting. Screen burn also may be permanent and considered a display hardware defect as opposed to a software graphics or display driver issue. For screen burn on your mobile devices, there are a few things you can do to fix the issue and, even better, prevent it from happening. Here are a few simple steps you can take.
This is the simplest solution and is frequently effective, especially when you catch image retention early on and want to fix it fast. Turn your phone off entirely, powering it down fully, and let it rest for a couple of hours. If the screen burn issue is minor, this gives the pixels enough time to recover, diminishing after-images, so your phone screen will look fresh when you power back on. This is one advantage of the versatile organic pixel layer used in OLED-based screens, which can correct itself more easily than pixels of the past.
If turning your mobile device off for a while doesn’t fully resolve your issue, a good next option to try is re-training the pixels on your screen to get them back into balance. The good news is, there are apps for that. For Android devices, the Google Play Store has a robustcollection of screen correctors and testersincludingOLED Saver. If you have an iOS device, then you can use an app likeDoctor OLED X instead. This app cycles your pixels through multiple colors and brightness levels, working towards resetting them.
If you don’t want to download an app, you can try checking out theScreenBurnFixerwebsite. It features a collection of videos with color slides and checkered patterns designed to help get your pixels back on track. Run a few of these and see if they fix your pixel problem.
You can be proactive about avoiding or mitigating screen burns on your mobile hardware by modifying various settings you might not have realized could help you. Make sure you are following guidelines like these:
Lower brightness settings:The higher the brightness setting, the harder your OLED pixels have to work, which can cause screen burn. If your mobile device is permanently set on a higher brightness, switch it to auto-brightness or a lower brightness level to prevent problems. For iOS 14, go toSettings > Display & Brightnessand toggle on theAutomaticsetting. TheOptions, True Tone,andNight Shiftsettings also help to modulate excessive brightness and prevent burn-in. On Android, go toSettings > Display > Brightness slideror toggle onAutoto automatically adjust brightness.
Set lock screen and sleep timers:Smartphones come equipped with automatic timers for locking and going into sleep mode, both of which turn off the screen after it hasn’t been used in a while. Make sure these settings are turned on and set to a minute or so. If you haven’t looked at your phone in one minute, it’s probably fine for it to shut off the screen and lock. This essentially prevents image retention because the screen won’t stay on long enough for it to happen. For iOS 14, go toSettings > Display & Brightness >Auto-Lockand choose which time interval you want. On Android 10, go toSettings > Display > Screen timeoutand choose the interval you want.
Get rid of menu, status, and navigation bars:Image retention can happen when you are actively using an app that has a permanent bar for tools or notifications, like when you’re playing a game or watching a movie, for example. When these bars don’t disappear, they cause screen burn after long sessions. Look for options to hide these icons and tools after a moment so they aren’t always present. Immersive modes for your mobile OS will also do this.
Enable dark mode:While it’s not a guarantee against image retention, using dark mode on your mobile device can help reduce the risk, particularly when it comes to overusing brightness levels. You can also try choosing dark keyboard skins. Enable Dark mode in iOS 14 withSettings > Display & Brightness > Darkor use theOptionsfeature to set a timer. On Android, go toSettings > Display > Night modeorComfort viewor set a schedule for either feature.
Screen burn can also become a problem on LCD mobile screens. While this may be a rare occurrence, it’s not impossible either. When it does, fixing it is a lot more of a challenge, since LCD pixels work differently from OLED screens. Therefore, you might have to accept that screen burns on your LCD screen are most likely there to stay. But before you give upall hope, you should still tryusing LCD Burn-In Wiper, whichcycles colors similar to its OLED counterpart to try to repair pixels.
Your last resort after failing to rectify screen burns with the previously mentioned methods would be to see if your device is under warranty so that you can switch out your screen or have it repaired by a professional.
The app does what it says it does: it reduces touchscreen lag and adjusts sensitivity. My phone was having issues detecting my taps, either by lagging or by not registering my tap. After using this app, all of the touchscreen-related issues were resolved! Just one issue: there"s ads on this app, one even covering the screen, and considering how infrequently one would use this app, putting in ads just seems like a waste of effort. Regardless, it does what it"s supposed to, and that"s great!
As mobile phone displays are much tougher than they used to be, it seems like they"re indestructible. Sadly, they"re not. Dropping your phone can often break the display. Your phone can no longer be considered useful.
Cracked your mobile phone display? Dropped it in the street, or crushed it playing football? Sat on it, even? You know by now that you"ve given yourself a headache. Can the phone be repaired, and if so, what are the costs?
Many services available online and locally will repair your mobile phone, for a price. But if you have access to the parts and they"re inexpensive, why not perform the procedure yourself?
You should also consider the non-monetary costs: time spent without a phone, data that needs archiving from the device. Hopefully your mobile platform"s cloud service can help here, or perhaps a desktop utility can check the phone"s contents.
Fitting a new display that costs the same as a replacement phone is pointless. However, if replacing the mobile phone screen is closer to $15, it makes sense to have a go yourself.
The most obvious location for a replacement display is eBay. Simply searching for the mobile phone model and the word display will turn up the required parts. Just remember to shop safely when using eBay.
In my case, "nexus 5 display" returned a wealth of accurate (and, sadly, slightly inaccurate) results. Take the time to check that the component you choose is genuinely for your device. Often, components may appear in the results thanks to a poorly written listing.
Amazon is also a resource for replacement screens, but you should also consider a general Google search as this will turn up specialist suppliers who might be able to provide a lower price.
Note that you may find listings that offer just the display, versus listings with half the phone"s chassis. Which one you buy depends on how complicated you want things to get. For example, just the display means melting the adhesive using a heatgun or hairdryer.
Alternatively, a replacement display kit that includes half the phone"s body will require components being transferred from the old body into the replacement.
These tools are included to remove the case and unscrew any components that obstruct replacing the display. For example, a mobile phone will have Torx screws under the battery cover that will need removing before you gently prize the case apart.
Note that spending money on these tools isn"t totally necessary. Sanding off the ends of a couple of plastic bicycle wheel levers will produce usable alternatives---otherwise, they can be sourced relatively cheaply.
There are so many different mobile phone models on the market (either new or used) that providing a standardized guide is next to impossible. Additionally, some models cannot be repaired without sending them back to the manufacturer.
To begin, remove (where possible) the rear cover, battery and identify where the Torx (or standard) screws might be hidden. Look under labels and beside USB ports. You might find screws in the battery cavity if you have a device with a removable cell.
These are often threaded through the different layers of hardware within the phone. Ribbon cables are delicate; easily broken, take care as damage to these could change the dynamic of the repair considerably.
Persuading your phone"s display to part with the body isn"t usually difficult. Pushing through the camera hole against the glass to begin with, slowly prize the glass display away from the body.
In this case, you won"t need to remove the display, but you will need to remove components (and even the motherboard) from the damaged device into the new body.
Narrow rolls of replacement adhesive can be bought online. Have some double-sided sticky tape laying around? Cut this into narrow 1 mm slivers, then apply the adhesive to the phone"s frame, rather than the glass.
Apply light pressure where the display meets the adhesive. Take care not to put pressure on the middle of the glass display. Excessive force can break even the strongest Gorilla glass.
Reconnect the relevant cables, locking them down where necessary. Place the components back in the case with care, checking that there are no cables or screws left over. Test the phone to check that it works.
The moment of truth: does the new screen work? Remember, a touchscreen display has two purposes: touch interaction, and displaying the phone"s operating system.
However, it isn"t always plain sailing. I"ve fitted a replacement display that caused the phone to overheat. Therefore, it is important to buy components from reputable sellers, and ensure you"re buying the right parts for your phone.
Most importantly, don"t walk into performing such a repair without some device-specific research first. Video guides are particularly useful; once you"re ready, get hold of the right tools and surprise yourself!
Here"s another tech problem you can solve yourself with a bit of time and effort: phone display flickering. And if you drop your phone into the water, don"t panic, follow these tips to help save it.
Companies like Facebook and Twitter have redefined social interaction. But what if “machines” like automobiles, bicycles, health monitors, appliances, instruments, and anything else you can connect to the Internet, could all become members of your social network, collect data you care about, and feed it back to you at just the right time? Nike+ is already doing this for your body, but every major industry, from healthcare to cars to home construction, is now building sensors and digital connectivity into their next generation of products. Companies like Ford, Pepsi, Verizon, and Procter and Gamble are also using “social machines” to reach new markets, improve brand/market awareness, and increase revenues. Social Machines is the first book for business people, marketers, product developers, and technologists, explaining how this trend will change our world, how your business will benefit, and how to create connected products that customers love. Explains how smart phones and tablets enable Social Machines
However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.
If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.
Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.
A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.
Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.
A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.
Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!
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.
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.
I had this problem 2 weeks ago, the touchscreen stopped working sporadically at first, then became constant, sometime it wouldn"t respond at all or I would touch one app and another would open. I tried restarting it when I actually could turn it off but didn"t hel[p.
2 days later...., the new replacement phone start doing the same thing, one again I have to go to Apple where they give me ANOTHER replacement phone. the said no way it"ll happen again. I figure "ya, just a fluke, third times a charm...."
If you have an iPhone, then probably you’ve come to appreciate the dependability that these devices afford for the consumer. User feedback is generally positive, which is why they consistently remain worldwide bestsellers. However, as with any electronic devices, software and hardware issues sometimes come up, and when they do, you must deal with them. An example of that would be if your iPhone’s screen is showing white lines on it. In this article, we’ll go over what this problem most likely signifies, as well as what you can do to solve it.
With some cases of a problem with your iPhone, it’s exclusively an issue with either hardware or software. White lines appearing on your screen does not fall into that category, as it could be either one of those things that’s the culprit.
There are a few different potential software problems that might cause white lines. In the case of hardware, the most likely scenario is that the phone’s LCD cable has gotten detached from the logic board.
A minor software glitch that’s causing the appearance of white lines on your screen might be counteracted by restarting the phone. It’s easy to do and not at all time-consuming.
If you own an iPhone 8 or an earlier model than that, you’ll need to press and hold the Power button. After a few seconds, a Slide to Power Off slider will appear on the screen. Slide it to the right, turning off the phone. After a couple of seconds have elapsed, press thePower button again until you see the Apple logo. This indicates that the device is restarting.
If you have the iPhone X or later, then you must simultaneously press the Sidebutton and either one of the Volume buttons. The Slide to Power Off slider will come up. Slide it to the right, turning off the phone. Then, press your Power button until the Apple logo appears, and the phone will restart.
If the white lines obstruct the screen so severely that you can’t see anything, then you might want to try a hard restart instead. This is a maneuver that abruptly turns the iPhone off and on again. The way that you do this varies depending on which generation of the device you have.
If you have an iPhone 6 or an earlier model than that, you’ll need to press and hold your Power button at the same time as the Home button. The Apple logo will flash on the screen if you have done it correctly.
If you’ve got the iPhone 7 or 7Plus, then you have to press and hold the Power button and the Volume Down button. Again, you’re looking for that distinctive Apple logo.
If you have an iPhone 8 or one of the newer models than that, you should quickly press and release your Volume Up button. Next, quickly press and release your Volume Down button. Finally, press and hold theSidebutton. When an Apple logo comes up, let go of your Side button.
It can take a couple of tries for you to get this right, but be patient and don’t give up. Once the hard reset is complete, it’s highly likely that the white lines will be gone if they were there because of a software issue.
If what you’ve done so far hasn’t worked, then a more severe software issue may have occurred. The one thing that remains is to put your phone in DFU restore mode. This is the most extreme restore that you can do for the device. Before you do that, though, you should back it up to be sure that none of your data is lost.
You can do a backup with iTunes if you like. Connect the iPhone to your laptop or PC by using an Apple-approved USB cable. Next, pull up iTunes and make sure that it is the most recent version. Under Devices on the upper left-hand side of the screen, you should see your iPhone. Where you see the option to back it up, do so. It might take a few minutes, but now you should be good to go.
If you want to back up the iPhone using iCloud, then you must open Settingson your device. Hit your name at the top of the screen, and theniCloud. Scroll down and hit iCloud Backup. Be sure that the switch is toggled to the green “On” position. Tap Back Up Now.
Now, you’re ready to do a DFU restore for your phone. DFU stands for Device Firmware Update. This will erase and restore all of the code on your iPhone, effectively getting it back to its original factory settings.
Plug your phone into your laptop or PC with a USB cable. If you have an iPhone 6 or below, then you can press and hold your Sleep/Wake button and theHome button for 8 seconds. Then, release your Sleep/Wake button but continue to hold the Home button. iTunes should say that it has detected an iPhone in recovery mode. At that point, you can let go of the Home button. Your screen should be completely black. Your phone is now in DFU mode, and you can restore the backup version that you made.
If you have an iPhone 7 or 7Plus, then you have to hold the Sleep/Wake button for 8 seconds along with the Volume Down button. After 8 seconds, release the Volume Down button, but continue to hold the Sleep/Wake button. When you see the message about the device in recovery mode, you can let go of the Sleep/Wake button, and the device should be in DFU mode. Now, you can restore the backup version.
This last version is how you can put the phone in DFU mode if you have a generation 8 or later. First, quickly press and release your Volume Up button. Next, press and release your Volume Down button. Press and hold your Side button until the screen goes black. Once it does, press and hold the Volume Downbutton while still holding the Sidebutton. After 5 seconds, release the Side button, but keep holding the Volume Down button. You will get the message about the phone being in restore mode if you have done it correctly. At that point, release the Volume Down button.
Since this operation is a little tricky, especially with the newer versions of the iPhone, you might not get it right on the first attempt. Try it a few times, and if you’re struggling with it, there are some excellent videos on YouTube that should get you pointed in the right direction.
If the DFU restore failed to get rid of the white lines on your device’s screen, then that’s a strong indication that the issue is happening because of a hardware malfunction. As we mentioned earlier, the most likely thing to have happened is that the LCD cable is no longer hooked up to the logic board.
Rough handling of the phone might cause this to happen. If you dropped it at some point and it was out of its case, that might have done it. Exposure to liquid can also sometimes cause those annoying white lines to appear.
You’ll need to take the phone to an Apple Store with a Genius Bar so they can look at it. You probably should not try to fix it yourself, since that would require opening up the device and tinkering with it, which would likely void the warranty.
If all that is happening with it is that the LCD cable needs to be connected again, that’s a quick and easy fix. There might be something more serious happening with the phone, in which case replacement parts might need to be installed. If the device is still under warranty, then that should cover it. If the warranty has expired, you’ll have to pay for the cost of the fix. It should be worth it, though, since those white lines can render your phone virtually useless until you figure out how to get rid of them.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.
LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.
Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.
Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray.
The chemical formula of the liquid crystals used in LCDs may vary. Formulas may be patented.Sharp Corporation. The patent that covered that specific mixture expired.
Most color LCD systems use the same technique, with color filters used to generate red, green, and blue subpixels. The LCD color filters are made with a photolithography process on large glass sheets that are later glued with other glass sheets containing a TFT array, spacers and liquid crystal, creating several color LCDs that are then cut from one another and laminated with polarizer sheets. Red, green, blue and black photoresists (resists) are used. All resists contain a finely ground powdered pigment, with particles being just 40 nanometers across. The black resist is the first to be applied; this will create a black grid (known in the industry as a black matrix) that will separate red, green and blue subpixels from one another, increasing contrast ratios and preventing light from leaking from one subpixel onto other surrounding subpixels.Super-twisted nematic LCD, where the variable twist between tighter-spaced plates causes a varying double refraction birefringence, thus changing the hue.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).
Displays for a small number of individual digits or fixed symbols (as in digital watches and pocket calculators) can be implemented with independent electrodes for each segment.alphanumeric or variable graphics displays are usually implemented with pixels arranged as a matrix consisting of electrically connected rows on one side of the LC layer and columns on the other side, which makes it possible to address each pixel at the intersections. The general method of matrix addressing consists of sequentially addressing one side of the matrix, for example by selecting the rows one-by-one and applying the picture information on the other side at the columns row-by-row. For details on the various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs.
LCDs, along with OLED displays, are manufactured in cleanrooms borrowing techniques from semiconductor manufacturing and using large sheets of glass whose size has increased over time. Several displays are manufactured at the same time, and then cut from the sheet of glass, also known as the mother glass or LCD glass substrate. The increase in size allows more displays or larger displays to be made, just like with increasing wafer sizes in semiconductor manufacturing. The glass sizes are as follows:
Until Gen 8, manufacturers would not agree on a single mother glass size and as a result, different manufacturers would use slightly different glass sizes for the same generation. Some manufacturers have adopted Gen 8.6 mother glass sheets which are only slightly larger than Gen 8.5, allowing for more 50 and 58 inch LCDs to be made per mother glass, specially 58 inch LCDs, in which case 6 can be produced on a Gen 8.6 mother glass vs only 3 on a Gen 8.5 mother glass, significantly reducing waste.AGC Inc., Corning Inc., and Nippon Electric Glass.
The origins and the complex history of liquid-crystal displays from the perspective of an insider during the early days were described by Joseph A. Castellano in Liquid Gold: The Story of Liquid Crystal Displays and the Creation of an Industry.IEEE History Center.Peter J. Wild, can be found at the Engineering and Technology History Wiki.
In 1888,Friedrich Reinitzer (1858–1927) discovered the liquid crystalline nature of cholesterol extracted from carrots (that is, two melting points and generation of colors) and published his findings at a meeting of the Vienna Chemical Society on May 3, 1888 (F. Reinitzer: Beiträge zur Kenntniss des Cholesterins, Monatshefte für Chemie (Wien) 9, 421–441 (1888)).Otto Lehmann published his work "Flüssige Kristalle" (Liquid Crystals). In 1911, Charles Mauguin first experimented with liquid crystals confined between plates in thin layers.
In 1922, Georges Friedel described the structure and properties of liquid crystals and classified them in three types (nematics, smectics and cholesterics). In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fréedericksz transition, the essential effect of all LCD technology. In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve". In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray.RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal.
The MOSFET (metal-oxide-semiconductor field-effect transistor) was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959, and presented in 1960.Paul K. Weimer at RCA developed the thin-film transistor (TFT) in 1962.
In 1964, George H. Heilmeier, then working at the RCA laboratories on the effect discovered by Williams achieved the switching of colors by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the George H. Heilmeier was inducted in the National Inventors Hall of FameIEEE Milestone.
In the late 1960s, pioneering work on liquid crystals was undertaken by the UK"s Royal Radar Establishment at Malvern, England. The team at RRE supported ongoing work by George William Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals, which had correct stability and temperature properties for application in LCDs.
The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968.dynamic scattering mode (DSM) LCD that used standard discrete MOSFETs.
On December 4, 1970, the twisted nematic field effect (TN) in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.Brown, Boveri & Cie, its joint venture partner at that time, which produced TN displays for wristwatches and other applications during the 1970s for the international markets including the Japanese electronics industry, which soon produced the first digital quartz wristwatches with TN-LCDs and numerous other products. James Fergason, while working with Sardari Arora and Alfred Saupe at Kent State University Liquid Crystal Institute, filed an identical patent in the United States on April 22, 1971.ILIXCO (now LXD Incorporated), produced LCDs based on the TN-effect, which soon superseded the poor-quality DSM types due to improvements of lower operating voltages and lower power consumption. Tetsuro Hama and Izuhiko Nishimura of Seiko received a US patent dated February 1971, for an electronic wristwatch incorporating a TN-LCD.
In 1972, the concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel was prototyped in the United States by T. Peter Brody"s team at Westinghouse, in Pittsburgh, Pennsylvania.Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.active-matrix liquid-crystal display (AM LCD) in 1974, and then Brody coined the term "active matrix" in 1975.
In 1972 North American Rockwell Microelectronics Corp introduced the use of DSM LCDs for calculators for marketing by Lloyds Electronics Inc, though these required an internal light source for illumination.Sharp Corporation followed with DSM LCDs for pocket-sized calculators in 1973Seiko and its first 6-digit TN-LCD quartz wristwatch, and Casio"s "Casiotron". Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968.TFT LCDs similar to the prototypes developed by a Westinghouse team in 1972 were patented in 1976 by a team at Sharp consisting of Fumiaki Funada, Masataka Matsuura, and Tomio Wada,
In 1983, researchers at Brown, Boveri & Cie (BBC) Research Center, Switzerland, invented the passive matrix-addressed LCDs. H. Amstutz et al. were listed as inventors in the corresponding patent applications filed in Switzerland on July 7, 1983, and October 28, 1983. Patents were granted in Switzerland CH 665491, Europe EP 0131216,
The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko"s R&D group began development on color LCD pocket televisions.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.compact, full-color LCD projector.
In 1990, under different titles, inventors conceived electro optical effects as alternatives to twisted nematic field effect LCDs (TN- and STN- LCDs). One approach was to use interdigital electrodes on one glass substrate only to produce an electric field essentially parallel to the glass substrates.Germany by Guenter Baur et al. and patented in various countries.Hitachi work out various practical details of the IPS technology to interconnect the thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.
Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain the dominant LCD designs through 2006.South Korea and Taiwan,
In 2007 the image quality of LCD televisions surpassed the image quality of cathode-ray-tube-based (CRT) TVs.LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank.Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer,transparent and flexible, but they cannot emit light without a backlight like OLED and microLED, which are other technologies that can also be made flexible and transparent.
In 2016, Panasonic developed IPS LCDs with a contrast ratio of 1,000,000:1, rivaling OLEDs. This technology was later put into mass production as dual layer, dual panel or LMCL (Light Modulating Cell Layer) LCDs. The technology uses 2 liquid crystal layers instead of one, and may be used along with a mini-LED backlight and quantum dot sheets.
Since LCDs produce no light of their own, they require external light to produce a visible image.backlight. Active-matrix LCDs are almost always backlit.Transflective LCDs combine the features of a backlit transmissive display and a reflective display.
CCFL: The LCD panel is lit either by two cold cathode fluorescent lamps placed at opposite edges of the display or an array of parallel CCFLs behind larger displays. A diffuser (made of PMMA acrylic plastic, also known as a wave or light guide/guiding plateinverter to convert whatever DC voltage the device uses (usually 5 or 12 V) to ≈1000 V needed to light a CCFL.
EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special gla
