how to repair an lcd display manufacturer

If the picture responds to input but displays a messy image, such as jumbled multicolored squares, the AV (audio visual) board may be damaged. This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.

The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.

Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.

Liquid crystal displays (LCDs) are the most widely used display technology. Their applications cover TV, mobile phone, appliances, automotive, smart home, industrial meters, consumer electronics, POS, marine, aerospace, military etc. LCD screen display problem can occur for several reasons.

Effect of environmental conditions on the LCD assembly. Environmental conditions include both the effects of temperature and humidity, and cyclic loading.

Effect of manufacturing process. With the development of LCD for more than 40 years and the modern manufacturing equipment, this kind if defects are getting rear.

Common failures seen in LCDs are a decrease in screen contrast, non-functioning pixels or the whole display, and broken glass. Different kinds of LCD display problem need to have different kinds of fix methods or make the decision not worthwhile to repair.

Broken glassIf you accidently drop the LCD and you find it broken on the surface but the display still works. You might just break the touch panel; you can find a repair house or find a youtube video to replace the touch panel. If you find the display not showing, especially you find the fluid leaking out. You need to reply the whole display modules.

Dim LCD displayLCD can’t emit light itself. It uses backlight. Normally, the backlight is not fully driven, you can increase the LED backlight to make a dim LCD display brighter. But if you LCD display has been used for a long time, it is possible that the LED backlight has to be the end of life (not brightness enough) if you turn on 100% backlight brightness. In that case to fix LCD screen, you have to find a way to change the backlight. For some display, it is an easy job but it can be difficult for other displays depending on the manufacturing process.

Image sticking (Ghosting)Sometimes, you will find the previous image still appearing at the background even if you change to another image. It is also called burn in. This kind of failure doesn’t need to repair by professionals. You can simply shut off the display overnight, this kind of problem will go away. Please do remember that displaying a static image for a long time should be avoided.

With the modern manufacturing process and design, this kind of failure rarely happens. Normally, it is caused by no power. Please check if the battery dead or adapter (power supply) failure or even check if you have plug in firmly or with the wrong power supply. 99% the display will be back on.

LCD has white screen – If a LCD has a white screen which means the backlight is good. Simply check your signal input sources which are the most causes. It can also be caused by the display totally damaged by ESD or excess heat, shock which make the LCD controller broken or the connection failure which has to be repaired by professionals.

Blur ImagesAs the LCD images are made of RGB pixels, the screen shouldn’t be blur like old CRT displays. If you do see blur images, they might be caused by two reasons. 1) LCD has certain response time, if you are playing games or watch fast action movies, some old LCD displays can have image delays. 2) The surface of the LCD is made of a layer of plastic film with maximum hardness of 3H. If you clean the surface often or use the wrong detergent or solvent which cause the surface damage. To fix damage on LED screen it’s need to be changed with professionals.

3. #If all the above is OK, measure the LVDS voltage value. Under normal conditions, the LVDS signal’s RX+/ RX-voltage value is about 1.2v, and RX+/ RX-difference value is about 200mV. At the same time, the resistance of the LVDS signal to ground and the resistance between the LVDS signal pairs can be measured (100 ohms). If there is an exception to these values, try replacing the ASIC.

1. #Confirm whether the COF on side X is hot compared with the normal temperature, whether there is fracture or wear crack, and whether the COF is burnt.

2. #Confirm whether the VAA is normal (normally about 17V). If abnormal, disconnect the RP32 to confirm whether it is caused by DC/DC loop or X-side COF: disconnect RP32, if the VAA is normal, the COF is bad, CO must be changed; COF can be Disconnect one by one to determine which NG disconnects RP32, VAA NG, try to change UP1; at the same time, confirm whether the continuity of the surrounding triode is OK.

4. #Determine whether the gate IC is OK. There is a signal test point on the back of COG-IC, and the green paint can be scraped for measurement confirmation; If there is a gate IC problem, which IC fault can be confirmed. The confirmation of gate IC fault is only for analysis when you are interested, and this method is not recommended.

1. #Measure GM1~GM14, the values are arranged from large to small. In general, a certain gamma value will be abnormal in the case of NG, then try to replace gamma-IC;

3. #Confirm whether the RSDS value is correct, normal RSDS is about 1.2v, and the signal difference is about 200mV; At the same time, we can confirm the resistance between RSDS signal (normal 100 or 50 ohms) and RSDS resistance to ground. If the voltage is NG, check if the ASIC and X-COF are hot.

Polarizer / CELL damaged To change the polarizer, a polarizer attaching machine is required The degree of whitening of the picture changes with different viewing angles

1. #Adjust the VR knob to see whether it can be adjusted and whether the screen performance changes. At the same time, confirm the VCOM value (about 7v), if NG, replace the VR knob.

2. #Confirm VGH/VGL voltage (about 30V VGH and -6v VGL), and confirm whether it is DC/DC loop NG or COF IC NG; The corresponding resistance of disconnected VGH and VGL can determine whether it is a DC/DC problem or a COF-IC problem. If it is DC/DC NG, try to replace UP1 or confirm whether the corresponding transistor is OK.

3. #If the whiteness changes significantly with the view Angle, and above 1&2 analysis is all OK, polarizer NG or CELL NG can be basically determined.

3. #Confirm whether the gate IC is OK. There is a signal test point on the back of COG IC, which can scrape the green paint for measurement confirmation; Or cut COF halfway from G3. If there is a gate-ic problem, which IC fault can be confirmed.

2. #Confirm whether there is 12V input, if not, confirm whether the connector is OK, and confirm the resistance value of 12V voltage to earth; If conn. NG, change conn.; If 12V is short-circuited to the ground, disconnect FP1 to determine the short-circuiting circuit.

3. #Confirm whether FP1 is open; if open, replaces fuse. If the 12V accessory of this model has a reverse diode, confirm the continuity of the diode and check whether it is burnt.

B. Confirm VAA resistance to ground at VAA test point of R plate (A short circuit usually occurs), disconnect the corresponding capacitance of the following 3 COF, and confirm VAA resistance to the ground again. If OK, replace the capacitor, if NG, replace COF. If VAA is still NG, confirm DC/DC loop as all models.

6. #Disconnect RP32 to confirm VAA, if NG, try to change the PWM IC (in general, it will be good), if still NG, try to change the gamma-ic or corresponding to the VAA several large capacitances (in general, it is rare, this situation is generally accompanied by VAA to the ground short circuit).

3. #Shaking module, if vertical lines disappear or reappear, then it can be judged that the possible cause is COF pin broken, and the crease should be found under the OM microscope.

4. #Press the LCD glass side of the panel, if the vertical lines disappear or reappear, it can be judged that the cause of poor contact, OM checking should be able to find the poor contact.

5. #If there is no display change in pressing, confirm whether ITO is damaged under the OM microscope, or pin signal waveform corresponding to needle COF.

Lamp line is broken Replace the lamp tubing Depending on the backlight structure, there will be different results. The failure of the performance may be a point-off, or it may be a backlight with a dark band.

4. #The above disassembly judgment can basically solve the problems of point-off in the market. If you can’t tell the truth, you can directly change the lamp tube.

Lamp line is broken Reconnect / replace lamp tubing Depending on the protection status of the power board, it may be a backlight with a dark band or it may be a point-off.

3. #Disassemble the backlight, confirm whether there is a short circuit with broken skin on the lamp strip, whether the plug of the lamp strip is fully integrated with the socket, whether the pin is aslant/off, whether the connector is off, and whether the LED bead is black and injured.

4. #The fault of the product is basically caused by the above reasons. If the appearance is fault-free, the lamp bar can be crossed to confirm whether the phenomenon follows the lamp bar, or the voltage of the lamp bar and the conduction condition between the lamp beads can be measured.

How to repair LCD displays? Three visual inspection methods can help you solve problems, including external inspection, internal inspection and electrical inspection.

(1) External inspection: LCD display inspection should start from the outside, according to the working mode of the machine to check whether the buttons and switches on the operation panel are normal, whether the power connection is good, whether the video signal line is normal, etc.

(2) Internal inspection: LCD display in the external inspection did not find any abnormalities, open the display shell, check the internal circuit. Observe whether the solder joints and connecting wires of components are virtual soldering, de-soldering, whether the pins are mildewed or not, whether the plug-ins are loose, whether the circuit lines of printed circuit boards are broken, whether the components are burnt, burst or leakage, etc.

(3) Electricity check: LCD display is connected to the power switch to observe whether the power indicator light is on, whether there is fire, fever, burning odor and smoking in the machine.

People often ask how to repair the LCD display. In fact, this is a very professional problem, because precision instruments can not be explained in one word or two, so today I will tell you

Liquid-Crystal Displays, or LCDs, provide outstanding quality and unparalleled clarity in visual media. LCD displays come in many forms, from television sets to smartphones, having set a golden standard for entertainment and visual technology. These displays operate with common parts and often are simple to repair if they begin to dim.

Exercise caution when determining how and even if you should repair a faint LCD screen. Some screens lend themselves more easily to repair than others, while you should not attempt to repair others at all. You should handle old screens, such as classic cellphones or any older or legacy LCD screens, with great care. Consider asking a professional to help you with repairs, as you could inflict permanent damage to these items. Carelessness and ignorance can also permanently damage modern screens as well. If your screen remains under a warranty, don"t void it by opening the device. Contact your manufacturer and have the company repair it for you.

A common culprit for a dim LCD screen lies in a malfunctioning fluorescent backlight, known as a CCFL failure. Every LCD varies in construction and size, so consult your manufacturer"s documentation on how to remove any outer casing and, if necessary, the screen itself, when working with a laptop or computer monitor. Other components, such as a copper ground or an LCD controller board, may obstruct your path. Take careful note of these items and their proper locations, then gently move them out of the way until you can access the CCFL bulb. The bulb may rest in its own slot, depending on the type of screen you"re working with. On either end, gently remove the rubber caps from the old bulb and place them on the new bulb. A power cable should attach at one end and may require you to solder it in place. When complete, carefully replace the CCFL and all other components within the display module, then test your LCD display module. It should return to its former brightness.

If a new bulb did not correct the problem, other hardware issues can cause the screen to dim. Take your display module apart once again and examine the power cord that attaches to the CCFL to ensure it attaches properly. It should make contact with metal or a lead on the bulb itself and should not attach to the rubber caps which will prevent or dampen the flow of electricity to the bulb. If this does not correct your problem, instead examine your LCD"s power supply. When dealing with a TV or stand-alone monitor, this becomes vitally important. You may need only to replace a cord that plugs into an outlet. If more severe, an entire power board inside an LCD TV may require replacement. If your device no longer remains under warranty, refer to your manufacturer"s documentation for more information.

Other components can contribute to a faint display on an LCD screen, including faulty capacitors, transistors and inverters. With proper electrical equipment, such as an voltmeter, you can measure the flow of electric current through some of these components to determine proper operation. While it is possible to replace these components if you possess adequate experience, you can also permanently damage your LCD device if you make a mistake. Consider a repair shop if you do not have professional training.

When your LCD display has broken, needs replaced or simply needs a technology upgrade, and you have design/equipment elements to consider, you will want to look for a replacement part instead of replacing the unit.Problems may arise when you are sourcing the new panel from your original manufacturer.For example, by the time your panel has degraded, your LCD may be end of life, making it difficult to source;original manufacturers may be charging premium prices for their replacementLCD parts.AGDisplays offers a drop in replacement service for customers who need to replace an LCD or LCD component when their original panel/part is unavailable;this service is also for customers who are looking for a cost effective, suitable replacement or upgrade to their existing LCD. AGDisplays offers availability of standard or custom high-quality LCDs of virtually all shapes and sizes.

Replacing or upgrading the LCD component of your equipment sounds intimidating. It is rather simple if you begin your search with AGDisplays.

You may receive notifications from your original equipment manufacturer about your LCD panel. There are a couple of announcements to pay attention to. The most important two are the end of life (EOL) announcement and the end of sale date. The end of life announcement will officialize a future cease production date for the indicated part number. It may also indicate the end of sale date, which is the last date customers are able to order the product through the manufacturer. After this date, the product will no longer be for sale. Typically end of life announcements come six to twelve months before the last time buy date. A few months later is when your last time buy will ship.

If you decide by this point that your equipment is well suited to use the LCD replacement, you may want to grab these panels when they get into the last time buy phase. If you find yourself ready to upgrade after EOL and last time buys have passed, don’t fret.A drop in replacement unit extends the lifecycle of your unit in the case of EOL or unavailability of original parts.

There are many signs an LCD will give the user to indicate that it may be due for replacement or upgrade. Even users who are not LCD experts will be able to tell when it is time to replace.

Outwardly, your LCD will show physical signs of damage such as a cracked or scratched, foggy or contaminated screen.Mostly, these damages are quickly noticeable to the naked eye and the first obvious sign that your panel may need a replacement. These are clear indications that the outside of your LCD has been damaged and is in need of evaluation or replacement. The application environment will determine the urgency in which you’ll want to replace the LCD. Cracks in the LCD may leave the LCD vulnerable to contamination and dust, which in turn can extend damage and/or decrease visual readability of the display.

Most LED technology estimate LED lifetimes to be upwards of 100,000 hours of useful life. This works out to be about six hours of usage a day—and 45 years of service, whew! So one can assume that LCD components will fail before the LED backlighting system will degrade. However, degradation does happen with long term usage. If your LCD is looking less bright than it should be, it is possible that a component in the display’s backlighting system needs replaced or upgraded.

LCDs that are broken internally may only show a black screen, a white screen, or even show no data when turned on. Other indications will be white/grey/black discoloration spots (called mura) of the display itself when it is turned on, regardless of the data/color that is shown on screen.

Another indication of a dying LCD aredamaged pixels. If you notice a small speck of white or black on your screen that does not go away, even as the screen changes, you may have a damaged pixel or two. There are a few different types of pixel defects, hot, stuck and dead pixels. Hot pixels present themselves as always ‘on,’ they always appear white in color. Dead pixels are always ‘off,’ and look black at all times. Now a stuck pixel is either stuck ‘on’ or ‘off’ so they may appear the same as a hot or dead pixel. These (sometimes) are solved by switching from bright to dark colored screens quickly to unstick these. However, this isn’t a reliable treatment for stuck pixels.

If you’ve notice defective pixels on your LCD screen, do not panic! Some manufacturers have a standard in which it allows a certain amount of pixels in production. Overall, if the LCD in question has an increased rebellion of pixels, whether hot, dead or stuck, the LCD may be of low quality or the pixels are going bad.

Sometimes white, black or multi colored streaks appear running horizontally or vertically along the display. If this is happening on every screen, this is a likely sign that something is wrong inside the LCD.

Signs of LCD degradation include those missing pixels, the dimming of screen brightness over time, and even the loss of color and contrast in a display. If you need more assurance the LCD is the problem, consult AGDisplays to discuss our replacement options.

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!

Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.

According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?

As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.

For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.

Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.

Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.

With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.

Over the years, LCD modules and LCD displays have grown in popularity. Companies in many different industries, including but not limited to the medical, automotive, consumer, food services, industrial, and technology sectors rely on at least one TFT LCD module or TFT LCD display on a daily basis. Although touchscreens are very durable and designed to withstand the hands of time, older modules and displays sometimes need to be repaired. When weighing the cost of having your displays repaired, you should take the time to consider your options.

After doing some research on the cost of repairs, many business owners find that it makes more sense to have their TFT LCDs replaced. Although units may cost less to repair initially, the cost of having to repair your older displays over and over again can add up. This is because older units may need to be repaired more than once. Even if multiple repairs will not cost any additional money, repairs lead to downtime and can have a tremendous impact on your business.

Older units in need of repair can have a long-term impact on a company’s bottom line. This is because outdated displays do not perform as well as new and improved displays. As many business owners have come to discover, new and improved touchscreen technology can increase efficiency, boost productivity, and improve customer satisfaction. This a top reason why so many companies decide to have a TFT LCD display or module replaced.

If you are thinking about having your older touchscreens repaired, then you should consider how having newer technology in place will help your business grow. Focusing strictly on the cost of replacing your displays can have a long-term impact on your business in more ways than one. For better results, you should consider all of the benefits of having new custom touchscreens specifically manufactured for your business. Ultimately, having new and improved displays in place for your employees and customers to use will be a business decision that pays for itself over time.

ELSIN provides warranty and post-warranty repairs of LCD screens for service organizations, LCD panel makers, manufacturers and distributors of monitors, laptops, TVs and individual customers.

The advantageous location of ELSIN in the center of Europe in Pilsen city in Czech Republic enables fast service to customers across Europe and especially in the regions of the Czech Republic and Slovakia.

As the only company in the Czech Republic we carry out repairs of LCD panels including replacement of polarization film and repair of defective lines / blocks for sizes of 10 ” – 65 ” with a capacity of over 2000 pieces per month.

For example: for Dell U2415 monitor the factory installed display panel is 24.0" LM240WUA-SSA1 manufactured by LG Display, which supports 1920(RGB)×1200 (WUXGA) display and has WLED backlight incorporated (no LED driver is present in the panel). The signal interface is LVDS (2 ch, 8-bit), a single 30-pins connector. There are other matching panels made by LG, Samsung, AUO and possibly others (abundantly available from 3rd party resellers), but the most important is that the mainboard LVDS connector signals mapping do match the LVDS panel specifications - as found in the panel datasheet.

buy a used display panel, or a used monitor with similar size and resolution (checking first the monitor model specifications / resolution / backlight type / panel make, model, datasheet).

The replacement job will require disassembly, and one should carefully observe the steps in the video tutorials other users have created and posted on Internet. Or even better, leave it to a licensed repairer or somebody who has proven practical experience and knows how to avoid risk of electrical shock, ESD damage to the electronic components or the display panel - and can offer warranty for their work. Pay extra care with the cables connecting the mainboard to the display (LVDS, LED backlight and menu button board) as they can be easily damaged when removing the mainboard.

I am an IT guy who discovered repairing electronics by need - when looking to fix the hardware related problems I encountered with monitors, laptops, computers, networking, printing, audio-video and so.

I found that working with resources disposed for recycling is a very efficient way to learn, and solve many problems without big expenses. I agree that the cost of repair at specialized centres could bear a high cost - considering that fixing requires time, experience and somehow be lucrative. But younger generations tend to break technological barriers easier, and with the help of readily available information consumers can solve problems themselves when manufacturers can"t.

You dropped your iPhone for the third time this week. Now you have to decide if you’re going to get your broken screen replaced at a local Apple repair service provider or if you’re going to start scrolling online to find the best options for a new or refurbished iPhone.

Let’s say you decide to have the screen on your old phone fixed up by a tech-savvy friend of yours so you can sell or exchange the old, beat-up iPhone 6 for a good deal on a new iPhone 13. Now you’re wondering, “Can Apple tell if I replaced my screen?”

Screen replacements come in a variety of different kinds, like LCD or OLED. Other types of smartphone screens include TFT and IPS. You may have heard of AMOLED or even Super AMOLED displays. Most of these touch screens are made by third-party manufacturers. All of these screens can function on an iPhone — and they’re cheaper than an original. So what’s the problem?

Apple says that all its screens are designed and tested for ‘Apple quality and performance standards.’ This is done before iPhones and iPads hit the shelves for the first time to ensure all Apple products have their proprietary technology like multi-touch, true tone, night shift, and haptic touch functioning properly.

While you may not understand all the jargon, this basically means that iPhone screens are immaculate in functionality — and we’re not even talking about the Pro versions here. There are many reasons why having an original iPhone screen is important, both as a buyer and as a seller. An original screen can go a long way in terms of performance, specifications, aesthetics, and exchange offers if you’re eventually looking to upgrade.

Getting your iPhone screen replaced by an authorized Apple service provider can be an expensive affair — but cheaper, aftermarket screens that aren’t from Apple often come with several issues.

To answer the question above: yes. Apple can tell if you’ve replaced your screen. As a matter of fact, you can check for yourself. In this guide, we’ll look at how you can check for genuine Apple iPhone screens, issues with non-genuine screens, and the difference between the two.

Genuine iPhones will use OEM parts. This means they’re the original equipment manufacturer for all their hardware. Every original Apple product goes through a rigorous quality check process to ensure every part, from the display to the speakers, is compliant with their standards.

Most non-OEM parts come from third-party manufacturers who use cheaper materials to make their screens. The costs are lower upfront, but, you get what you pay for. It"s likely that you"ll have to keep replacing your screen at iPhone repair shops because third-party screens perform poorly and lack longevity.

This is why it’s important to get OEM parts, even if it’s a little more expensive. Your iPhone will perform at an optimum level, as Apple meant it to, and you’ll safeguard your warranty. Original parts also help with resale value if you eventually look to sell your iPhone or exchange it for a newer model.

If you own an iPhone 11, iPhone 11 Pro, or any of the models after it and are using iOS 15.2 or later, you can follow these steps to check the parts and service history of your iPhone.Go to Settings.

If the display is non-genuine, pre-used in another iPhone, or not functioning as it should, you’ll see “Unknown Part ! ” appear just below the serial number, next to Display.

Another quick way to check whether your iPhone screen is genuine is by shining a flashlight on it. You just want to shine the light directly on the iPhone’s screen.

Focus on the reflection of the light on the display. Fake screens tend to have grid lines on them, which will show up under a flashlight. These could be running across the screen horizontally, vertically, or both. The most common causes for this include software incompatibilities, hardware failure, or screen damage.

The last few iPhones to be released all have a maximum brightness level of around 1200 units. This means that iPhone screens get very bright and usually have best-in-class color accuracy.

You can use this to check if your iPhone’s screen is genuine. Simply bump the brightness slider up to maximum brightness, and open a solid black picture. You can head over to this website for a completely black screen.

Once you’re on this screen, zoom in and look at the display. If you have a genuine Retina OLED screen, it will look pitch black — as if you haven’t turned on your iPhone.

However, if the screen replacement process was non-genuine, you might have an LCD screen that isn’t from Apple. You can tell if you have a non-genuine screen if you notice color mismatch, specks, or marks of white or grey. Anything other than solid, fullscreen pitch black is not an original iPhone display.

If you want to get the entire lowdown on the authenticity of your iPhone, you can get a complete device certification report. This is especially useful if you’re looking to buy or sell a used phone.

A device certification report will give you your device status, carrier details, and phone repair history, among many other things. The entire process only takes a few minutes.

If you’re looking to sell your iPhone or buy a refurbished one, making sure all of its parts are genuine through Phonecheck’s device certification report can help you save time and put a proper valuation on your phone. Don"t buy a used device without a Phonecheck Certified History Report.

Having a non-genuine screen on your phone can cause several issues. Not only this, but the chances of selling or exchanging your phone for maximum value will substantially decrease.

One of the most common issues with a non-genuine touch screen is multi-touch. Non-genuine screens will not be as prompt or accurate as genuine iPhone screens. Some of the signs of a non-genuine screen are:Missed screen touches or touches not registering in the intended area.

Another common issue with non-genuine iPhone screens is that there could be LCD display panels that aren’t from Apple. Original iPhone screens usually have Retina or Super Retina displays made from an OLED panel that is incredibly bright and color accurate.

If you notice the following issues with your screen’s display, you might have a non-genuine iPhone screen:iPhone"s true tone feature does not work properly (this is when your screen uses different sensors to adapt the screen"s color to the light sources around it).

Apart from the more common issues related to multi-touch and display brightness, you may experience the following issues with your iPhone if you have a faulty screen:Your iPhone does not turn on.

With some non-genuine iPhone screens, digitizers tend to malfunction, creating dead areas in the screen (usually the bottom) where your touch commands have no effect. A digitizer is a layer of glass that converts analog movements like your touch commands and gestures to digital signals that your iPhone can understand and interpret. The digitizer rests over the device"s LCD or OLED display.

While original iPhone screens may be slightly more expensive, they’re the screens that were initially manufactured specifically for Apple iPhones. You can slap a third-party screen on an iPhone, and it will work, but the performance will be nowhere near as seamless. Non-genuine LCD panels will have lower brightness levels and weaker contrast. The colors won’t pop and the screen will feel coarse to the touch.

As mentioned in the previous section, non-genuine screens have tons of issues when it comes to multi-touch, true tone, night shift, and other features that Apple meant to be enjoyed exclusively on an iPhone.

A non-genuine screen’s touch will be inaccurate, the iPhone won’t respond as well, the screen won’t be as smooth to the touch, the brightness will flicker on its own, the battery might deplete quicker, and you may experience a lag in day-to-day usage. With a genuine Apple-approved iPhone screen, you are far less likely to experience these issues.

A genuine iPhone screen is just as important on the day you buy it as it is when you decide to sell it. If you’re looking to sell your phone or hand it in to exchange for a new iPhone, the value of an iPhone with a genuine screen will always be far higher than an iPhone with a non-genuine screen.

Non-genuine screens will show up in your device’s parts and services history, and you’ll end up selling your iPhone for way less than it could have. There’s a good chance that you will pay for a screen a third time after your first non-genuine replacement fails to work properly. It’s best to get a genuine iPhone screen replaced with another genuine iPhone screen.

It’s likely you’ll have a more durable screen, better performances, and fewer problems in the long run until you decide to sell your phone for the best price available.

It’s clear that while a genuine iPhone screen may be more expensive than third-party replacement counterparts, the pros far outweigh the cons. Not only will you enjoy using your phone more, but you also won’t have to break the bank when you want to upgrade.

Speaking of upgrades, if you’re looking to buy or sell a used iPhone, we highly recommend a complete device certification report from Phonecheck. This report will help uncover any issues and give you an in-depth record of your iPhone.
