difference between digitizer and lcd screen made in china
As an official phone repair provider who has been in the business for almost a decade, one unique question people ask when they visit our service centres to replace their phone screen is: "what"s the difference between original and copy phone screen?"
Well, the answer is, there are many differences between these two screens, which is mostly in their quality. And while “copy” phone screens are somewhat cheaper than the originals, it doesn’t justify the difference in quality. So, before you regret replacing your phone screen with a forbidden part, the tips below will tell you the critical differences between original and copy phone screens.
Generally, phone screens manufactured from your brand"s factory are the original ones while ‘Copy’screens are the ones designed and produced by third-party manufacturers and factories that are not related to your brand.
Many people usually like to go for copy screens because of their cheaper price. However, the "real" differences between original and copy screens lie in their quality, and here’s what you need to know about them.
One of the principal issues with "copied" phone screens and why it differs from the originals is touch and digitizer problems. And that"s a big problem since you"re going to control the device with the touchscreen anyway.
As far as we could remember, phone manufacturers build the touch panel/digitizer with the LCD itself, while the copied screen manufacturer build it separately on the surface glass. Hence, there"s a difference in touch sensitivity. Additionally, copied phone screens usually drop the high touch sampling rate, meaning your screen may not respond to your touches faster.
Here"s also another major issue with the digitizer on copied phone screens. When you crack a copied screen accidentally, the touchscreen stops working, stopping you from accessing the device until you fix it again. Meanwhile, the touch on the original phone screen works perfectly, even after undergoing severe cracking.
Besides having touch problems, most copy phone screens usually have poor display properties. That means you get lower brightness, colour accuracy, sharpness, contrast, etc. And when the display isn"t great, watching movies and viewing other content becomes boring.
For instance, if the original screen is supposed to have 480 nits of brightness, but the copy screen has just 200 nits, the screen becomes unusable under bright lights. Moreso, copied phone screen seems to have more blue light, which, in return, affect your sight and disrupts your sleep at night.
Among others, copied phone screens drop higher refresh rates, and that"s a bummer since most phones come with at least 90Hz refresh rate screens. What that means is the copied screen won’t feel smooth as it’s supposed to be.
It"s not all about the display quality. A copy phone screen may also affect other parts of the phone system if its specifications don"t tally with the original one. In such a case, it could drain your battery at an alarming rate, or at worse, damage your backlight.
If you happen to have a phone with an in-display fingerprint sensor, then replacing its screen with a copied one is not an option – it’s going to mess with your fingerprint accuracy.
We know copied phone screens for their poor quality, and it also extends to the fingerprint sensor. Hence, it takes a longer time to unlock your device. And in other cases, the security of the sensor is not accurate. We"ve seen situations where phones get unlocked with many unregistered fingers after replacing the screen with a copied one.
If you care about your phone"s security and you don"t want a sluggish fingerprint sensor, then we recommend you only go for the original phone screen replacement.
That brings us to the last difference we’re going to mention between copied and original phone screens. They manufacture copied phone screens with poor glass materials. Hence, they break quicker than the originals. And when they do, you’ll be left with only one option: to replace the screen again.
The major reason for choosing the official service centre over third-party/local repair shops summarizes what we"ve said earlier. The official service centre is the reliable place to get original phone screen replacement parts.
Why? As of today, smartphone phone manufacturers/brands release genuine spare parts only to the official service centres and affiliated repair centres. That means third party repair shops get their spare parts somewhere else: usually third-party factories/companies not related to your phones brand.
Besides offering you the original screen spare parts, the official service centres also have other advantages. These include certified and well-experienced technicians to fix the screen, the use of modern tools that won"t damage your phone further, and most importantly, a reliable warranty. Local repair shops usually don"t offer these features; most especially a reliable warranty, which means you"re on your own if the replaced screen gets faulty afterwards.
As far as choosing the official service centre is concerned for genuine screen replacement, then you shouldn"t shy away from Carlcare Service if you own a TECNO, Infinix, or itel phone with a cracked screen.
We"re the official service center for these three brands to cater for your mobile repair needs. And for screen replacement, Carlcare delivers excellently. Our brand-trained technicians replace your cracked screen with genuine OEM parts at affordable rates.

There are several display panel manufacturers in mainland China of which JDF(BOE) and TM(Tianma) stand out noticeably. JDF has gradually transformed its 6th production line into small-to-medium-size displays since 2014 and now JDF proceeds this plan and concentrates production capacity in this field in an all-around way.
As a matter of fact, TM(Tianma) has already transformed its display size and capacity altogether in late 2013 in prior of JDF(BOE), focusing on small-to-medium-size displays.
In addition to this, though SC which was vigorously supported by Foxconn had been performing mass production for LTPS, TFT, LCD displays at the beginning of 2012, did not make a great progress for the reason that SC failed to neither win over the Apple iPhone orders and nor get authorization in CG Si and IGZO technology of Sharp.
But do you know which iPhone 6 LCD made by these three display penal manufacturers is more cost-effective? Let’s go on with this article and sort things out. Not too long ago, REWA has analyzed the JDF(BOE) and LT(IVO) China made iPhone 6 LCDs in some ways. After several months’ development, how is the situation now? We have tested 3 mainstream China-made iPhone 6 LCDs by JDF(BOE ), TM(Tianma) and SC from aspects of “Appearance” and “Function” in order to make a comparison with OEM ones and give us clarity of thought.
After installed in the mobile devices, it’s much easy for us to find that all these three China made LCDs have a small gap between the LCD and device body, especially SC.
It can be observed visually that LCD Display and Touchscreen digitizer flex cable made by JDF, TM and SC are different in texture. 5) Structure Generally speaking, there are two kinds of mainstream cell phone display constructions of formation, “G+G” and “In-cell”.
Compared with the In-cell structure of OEM LCD, JDF, TM and SC which use G+G touch screen display technology thus cause their overall thickness greater than the OEM ones.
Testing Touch screen digitizer by moving the app icon in all directions including swiping from the edge of the screen, JDF, TM and SC display have no problems with touch function.
Testing LCD display in the pure color of gray, white and black, a part of JDF, TM and SC LCDs have somewhat degree problems of backlight leakage, but it does not affect the normal use and can be ignored in a certain sense. Note: The severity of this problem in the actual situation is a lot more slight than the captured pictures above.
After playing video for 72 hours, JDF, TM, SC have no obvious differences with the OEM ones. CONCLUSION From a series of tests we can find there are only a few differences between OEM display and China made LCDs. In terms of quality, JDF & TM are better than SC. For Price, JDF is more favorable than TM. Therefore, on the market condition that OEM LCDs being out of stock, JDF LCD is the most cost-effective choice for you. Want to order our products?

Not too long ago, we’ve just got some samples of the new China Made iPhone 6 LCD Display. No doubt that this will be another option for all who are suffering from the high price of the iPhone screens. Let’s take a deep look of these screens.
At the moment, there are two companies producing the iPhone 6 LCD screens, one is LT, the other one is JDF (no iPhone 6 screens made by TM are available now). Below are some detailed comparisons after our tests.
When taking a closer look at both of the LT and JDF iPhone 6 screens under direct light, you’ll see the digitizer textures. While for the original screen, the textures had been hidden by a special painted layer.
The glass lens of LT made iPhone 6 screen is far too thin compared with the original one, which can’t secure the display well. At the same time, thinner glass lens will make the home button stick up above the screen. While for the JDF made the screen, a plastic layer has been added to make it thicker.
It’s hard to be realized through eyes, but it’s easily to be touched. When you grab the iPhone 6 with LT made screen, it’s hard to ignore that annoying uncomfortable feeling. At this point, the JDF made screen is much better.
High and low temperature tests have been applied to both the LT and JDF iPhone 6 screens. Both of them have survived and worked well after been putted in a 55 centi degrees room for 2 hours and -5 centi degrees room for 2 hours.
Through our tests, the first version of both the LT and JDF displays are not good choices for the repair industry. The obvious color differences, thickness differences still need to be improved. If you have any questions regarding the LT/JDF iPhone 6 screens, please leave your comment below, we’ll try our best to answer it.
With the lack stock of the original iPhone 5 & 6 series LCD screen, the China made LCD screens becomes more and more popular among the repair shops. As the originaliPhone 6 Plus LCD screenprices are still high and not likely to fall down, plus more and more repair shops are tending to accept the China made LCD screens replacement instead, therefore, China made iPhone 6 Plus LCD screen appeared on the market naturally.
Recently we have got some samples of the China Made 6 Plus LCD screen, which have been called ‘LG 1:1 version’ on the market. We did some tests with these samples and found some differences compared to other China made LCD screens.
After tests, we found some differences in LCD frame height, glass screen thickness and the home button location among these 5 samples. You may wonder why these differences exist while they are sourcing from the same manufacturer?
Thus we need to learn the production process of the China made LCD screens, which was assembled by the 3rd party manufacturers, who purchased the China made LCD,LCD frame,glass lens,metal shields, screen foam and digitizer from different manufacturers, which could be original or high copied ones. Since there are some differences among theseglass lenses, LCD frames and so on, even though they shared the same LCD, there will still be some difference.
There is no doubt that significant differences existed between these 2 kinds of LCDs whether in display effect or working stability. In pursuit of greater profits, there is no strict requirements and standards for China made LCDs production process as long as the LCDs can achieve the basic using requirements. Therefore there is quite a gap in color difference, viewing angle and working stability compared to original ones, as the LCDs which are designed for the other brand cellphones, after replacing the IC and flex cable, have been inspected strictly before flowing to the market. (Such as the Samsung GalaxyS3 LCD screen assemblywhich are transformed from the GiONEE phones. Due to the few original stock in availability, most of the S3 LCD screen assemblies are produced by Samsung through transforming GiONEE LCDs.
It is said that these China made iPhone 6 Plus LCD screens are transformed from the MeiZu Meilan Note LCDs (Also features 5.5 inches) which are produced by Sharp and AUO, the overall performances of these LCD screens are better than LT/TM/JDF’s. And what’s big different from the other LCD screens is that there is one more LCD drive IC on the screen flex cable.
Because of the big production MOQ and long R & D cycle, the customized China made LCD screens had some difficulties intechnologyimprovementwith the changes of the marketing demands, while the original LCD features higher quality and reliability.
For these China made iPhone 6 Plus LCD screens, theLCD frametending to pop off and LCD screens are thicker. But in display effects, China made iPhone 6 plus LCD screens are better than5 series. Those customers who cared more about the prices will have one more choice once the improvements of the China made iPhone 6 Plus have been implemented. And we also will continue to focus on the China made iPhone 6 Plus LCD screen assembly.
Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.
Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.
“Original” screens are those containing LCDs manufactured for Apple. “Copy” screens are compatible replacements entirely designed and manufactured by third-party companies not associated with Apple.
LCD display panel can have poorer resolution (i.e. looks “coarser”), worse brightness, contrast and vibrancy and reduced refresh rate amongst other problems.
Changes in specification from original can result in battery and performance issues. Certain badly-engineered screens could even damage the backlight circuitry.
Customers who bring their iPhones to us for a screen repair are offered two choices of replacement- an original or a “copy” screen. The most common response is “Is there a difference- and which one would you recommend?”
Originals are those screens containing LCDs that were manufactured for Apple. So-called “copy” screens are compatible replacements, but designed and manufactured entirely independently by third-party companies, typically in China.
Our answer is simple- the original screen is the one we’d go for ourselves, every time. Some people think we make more money on them, but this isn’t the case. We recommend originals because they’re far higher quality and the price difference is fairly small.
We’d rather only fit original screens. The only reason we don’t is that many people will shop around and choose purely on price. As such, we need to offer the cheaper copy screens to remain competitive and avoid losing these customers. In some cases, they didn’t even know there was a difference in the first place- especially since it’s not in some shops’ interest to draw people’s attention to the issue!
This may well be the worst copy screen we’ve ever come across. As a result, the unfortunate customer has ended up paying twice to have their screen replaced- we’re sure that had they been properly informed, they would have chosen an original in the first place.
While the difference in price between copies and originals can vary across devices, it’s generally around £10 – £14 extra to have an original screen fitted. This really isn’t a lot considering the improved quality and reliability.
We compare our prices to our competitors- and we know that we come out of it favourably. While we have to offer copy screens to remain competitive, we always advise customers to go for the original.
When you’ve spent- directly or indirectly- several hundred pounds for an iPhone with a Retina display, it doesn’t make sense to replace it with a lower-quality screen that can make a £400 phone look like a £40 one! Not only that, but you’re likely to have fewer issues, and a longer-lasting screen.
There’s nothing stopping any random person without training or experience opening up a smartphone repair shop. As a result, the industry is full of companies with little skill or experience who are only interested in getting hold of your money and installing the cheapest parts they can find.
Many- if not most- don’t even acknowledge the existence of copy screens, let alone explain the difference to the customer. Hardly in their interest to do so if they only fit cheap, low-quality copies. Some of them can hardly be blamed- they know so little, they’re not even clear on the differences between OEM, non-OEM and copy displays themselves! Others can be more deliberately misleading… and some outright lie.
Generally, these shops are looking for the cheapest price on replacement screens.. When offered a copy at a half or a third of a price of the original, they’re going to go for that. That might be fine if they offered the customer a cheaper price- what we disagree with is selling “supermarket beans” (i.e. the copy screens) at “Heinz beans” prices!
Heading towards the “blatantly fraudulent”, we’re aware of companies that shamelessly fit copy screens while claiming them to be original. Worse, they’ll take your broken original screen and sell that to a recycler for more than they paid for your copy!
Obtained or manufactured “off the clock” via the same production line that produced them for Apple- in some cases, from the stockpile of parts that didn’t meet Apple’s standards, or
Apple tightened up their supply chain around 2015, which reduced the number of screens available for repairs and increased their price dramatically. A lot of companies went bankrupt, and Chinese manufacturers responded by making their own “copy” screens from scratch. At first, these weren’t much cheaper than the Apple ones, but the price soon fell.
We should be clear that- despite the name- “copy” screens aren’t direct copies of the Apple originals. Rather, they’re compatible replacements that have been designed from scratch and- as a result- vary in some respects that have an effect on usability and quality.
One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.
Although there are only a small number of manufacturers of the bare LCDs themselves, these are then bought by countless other companies who add the remaining components needed to turn these into a complete working screen. As a result, you could easily end up with an LCD from the best “copy” manufacturer, but the digitizer/touch (as part of the separately-manufactured glass) from the worst.
There are countless digitizers out there, and you can only take the supplier’s word that the quality is good. Many ship good ones at first, then switch to cheaper parts to make more profit. This is particularly bad with the iPhone 6S and 6S+, since Apple moved the chips responsible for touch processing onto the LCD itself. As a result, you’re not just getting a copy screen- you’re getting copy chips too.
The performance specification (power drain, etc.) of most copy screens isn’t identical to the originals. As a result, they can drain the battery more quickly and mislead the operating system which was optimised for the original screen design.
It’s even possible that this mismatch could damage your backlight. We do a lot of subcontracted repairs for less-experienced shops, and get backlight repairs in almost every day. We’ve had cases where we fixed the circuit, fitted the new copy screen to test it, and had it break the circuit again!
Copy screens can disrupt the touch ID fingerprint reader. With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. Frequently the home button flexes on aftermarket designs don’t work properly and stop the touch ID working- annoying if you use it to unlock the phone or log in to your bank.
We’ve seen many lift away from the frame that holds them in place. This usually results in the flex cable getting torn, and the screen needing replacing. You don’t even need to have dropped the phone- this often happens through general everyday wear and tear.
That brings us to another major issue with the copies. When you drop an Apple original, the glass often breaks, but if the LCD itself is intact, you can continue to use it until it’s fixed. With the copies, the touch/digitizer is on the glass and stops working when that’s broken. Even worse, the LCD itself is more likely to break due to the thinner and more fragile glass.
We’re not convinced this will happen, since Apple recently changed their repair policy to accept iPhones with third-party screens. However, it is possible that copy screens could be stopped from working via an iOS update, since those make a number of security checks.

I need to replace my cracked digitizer/glass on my OnePlus One and it seems changing only the digitizer is kinda hard so next thing is to get the full LCD to replace.
It seems logical that lcd + frame is easier but it seems it requires to move components/motherboard around which for me seems more prone to mistakes and problems then just buying an LCD and putting it into my old frame.
One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.
Last week I had the opportunity to tour BOE Technology Group’s Gen 10.5 factory in Hefei, the capital of China’s Anhui Province.This was the third factory, or “fab” that Beijing-based BOE built in Hefei alone, and in terms of capability, it is now the most advanced in the world.BOE has a total of 12 fabs in Beijing, Chongqing, and several other major cities across China; this particular factory was named Fab 9.
Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.
On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.
For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.
The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.
LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.
Since most display manufacturing has to be done in a cleanroom and handling the glass requires such precision, the factory is heavily automated.As you watch the glass come in, it is placed into giant cassettes by robot handlers, and the cassettes are moved around throughout the factory.At each step, robots lift a piece of glass out of the cassette, and position it for the processing machines.Some of the machines, like the ones that deposit silicon or ITO, orient the glass vertically, and put them inside an enormous vacuum chamber where all the air is first pumped out before they can go to work.And then they somehow manage to deposit micrometer thin layers that are extremely uniform.It is a miracle that any of this stuff actually works.
It obviously costs a lot to equip and run such a fab.Including all of the specialized production tools, press reports say BOE spent RMB 46 billion (US$6.95 billion). Even though you don’t see a lot of people on the floor, it takes thousands of engineers to keep the place running.
The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.
Since the iPhone 7/7 Plus has been released for quite a long time, finally the China made iPhone 7/7 Plus screen replacementscame out in the market. we’ve got some iPhone 7 series LCD screen replacements samples and done some tests on them, now let’s take a closer look at these new iPhone 7 series LCD screen replacements!(TianmaandLGsources for testing)
After installing all the sample screens to the iPhone 7/7 Plus rear housing assembly, we found that all the China made iPhone 7 series screen replacements are fitting well just like the original ones - the home button fits well, the screen assembly and the rear housing also fits well.
From the picture below, we can see that there is no difference between the China made iPhone 7 series display and the original ones, however, back to the rear side, we can easily figure out which one is which, cause the original one has Apple logo on it while the China made screen has none.
By comparing these two iPhone 7 screens, we can find that the screen flex cables are much different, there are extra IC on the China-Made iPhone 7 screen while the original one has none. And the original iPhone 7 series screen flex cable is integrated together while on the China-Made iPhone 7 series screen the touch function flex cable is soldered to the display and 3D touch flex cable.
Another difference between the original and China made iPhone 7 screen replacements is the exposed IC on the after-market iPhone screen, just like other China-Made iPhone 5 or 6 series screen replacement, which has more potential risk of electrostatic damage and more likely to get damaged and this problem needs to be improved.
During our test, we found that the display color between our after-market iPhone 7 screen and original screen seems a little different although they are not effecting the touch function. And to be honest, there may have some black dots on the screen because of impurities within the screen module when laminating the LCD and backlight together, without any doubt, this can be solved with technical improvement.
The screen touch sensitivity is another big concern for all of us, luckily, during our test, almost all home button and touch functionality on both iPhone 7 and 7 Plus works well, except one piece of iPhone 7, the 3D touch function is not acting so well on the central part of the screen.
The China-Made iPhone 7 series LCD screen assembly replacement still remains to be improved in quality and performance compared to the original ones, the exposed IC, heavier screen flex cable ribbon, and the screen color difference, the touch function stability, although the price is attractive. However, the China made iPhone 7 series screen replacement is under the improvement, and sooner or later their quality and performance can be quite close to original ones and acceptable, if you"re going to stock up some non-original iPhone 7 series LCD screen replacement, pay more attention and we’ll keep you updated with further information about after-market iPhone 7 series screen replacement!
