The Difference between OEM Refurbished and OEM Assembled?

One of the most common misconceptions we see in the iPhone repair business is the true meaning and understanding of the definition of OEM Refurbished LCD Screens and OEM Assembled LCD Screens. Now Let’s distinguish them step by step.


First of all, we need to know the process of manufacture.

OEM Refurbished LCD screen

1. Raw material source: broken glass but with good lcd and flex cable


2. Remove the broken glass by professional equipment;


3. Test the function of lcd screen, ensure the lcd works well;


4. Clean the LCD Screen and test it again;


5. Laminating LCD Screen with New glass lens with Frame pre-installed;


6. Test the function after finishing the lamination.

OEM Assembled LCD screen

1. Raw material source: broken glass or flex cable but with good lcd;

oem assembled 1

2. Remove the broken glass or flex cable by professional equipment;

3. Assembling the flex cable to the LCD Screen (Very important);

oem assembled 2

4. Test the function of lcd screen, ensure the lcd works well;


5. Laminating LCD Screen with New glass lens with Frame pre-installed;


6. Test the function after finishing the lamination.


Secondly, let’s see the difference.

In the process of OEM Refurbished, We must understand the focus: only glass lens is replaced, the lcd and flex cable is original. So the function of lcd assembly is stable just like original one.

While the OEM Assembled lcd needs to reassemble flex cable which is hard to operate and control, so the function is not steady.

Finally, You get what you pay for.

We Future Supplier always offer OEM Refurbished lcd screen assembly.To a large extent can avoid the instability problem.  We also analyse the instability of OEM Assembled lcd assembly such as no touch, Intermittent without touch, Screen display is prone to lines or black screen. These problems have a great relationship to the assembling flex cable.

So if you want to buy the cheapest LCD screen from your supplier, be careful for these problems.

Can iPhone 6 Refurbish to iPhone 7?

Recently, we have heard a lot of rumors about refurbishing iPhone 6 to iPhone 7.
But whether it is true or not, we can analyze it from phone structure.

First let’s check the structure of iPhone 6:



The structure of iPhone 7:

iPhone 7 teardown

LCD Assembly Components:
Backlight/Display Module/Display Driver IC/Flex cable/glass lens/frame

spare parts

The similarity:
1. LCD Display Module: 4.7 inches
The basis of refurbishing and recycling.

lcd Comparison

2. The differences: Backlight/Flex cable/Driver IC(data difference)/Glass Lens/Frame

Backlight difference:

Driver IC difference: If refurbishing iPhone 7, you need reinstall driver IC.

Glass lens difference:

Glass lens comparison
If it is available for converting iPhone 6 to iPhone 7, we need the following spare parts.

iPhone 6 VS iPhone 7 LCD assembly

1. Open Module parts: iPhone 7 Flex cable/Glass Lens/Frame/Backlight
2. Valuable Parts of old LCD: Gravity sensor flex cable of Backlight/ Driver IC/ Good LCD

The compatibility of Display Drive, which may lead to functionality unstable, No display and touch function after your iPhone upgrades to the newest version, and the problems will not appear at once until you used one to two weeks.

There are no free lunches in life, if you get cheap spare parts, then you need to take higher risk.


1. If Driver Module is not original, the display resolution will be different, LCD Display will also have color distortions.
2. The glass lens and frame are produced by open mold, it may appear installation problems.

All in all, No matter it is available for refurbishing iPhone 7, we need to have the right attitude, just believe: you get what you pay for, the higher the price, the better the quality.

Which Parts of Your iPhone 7 Really Cracked ?


From Etradesupply’s What you should know about replacing screen parts!, we know the basic ways to tell which parts (front glass lens, digitizer, LCD)are broken. Let’s review it again.

If you’ve damaged your front glass only, then the touch and display function will not be effected except for several cracks or scratches on your cellphone display, and that sounds like a lucky thing for you compared to other situations.

If the touchscreen broken, you’ll lose the touch function, but you could still see what is happening on the screen, and the screen should still function as normal.

When the LCD is broken, the panel will have dark blobs or spider web-looking cracks (or both). And maybe can no longer see anything on the screen. It can be verified if the screen has lines within it, or if it has a “spilled ink” look.

We can judge some problems from the appearance, but for more detailed information, we need to test the LCD screen. So the process for judging more issues is as following:

1. Sight: Look at the appearance, check the outline is good or not.


2. Test: if the glass is good, we need to test the touch function and tear the backlight for ensuring the LCD Function.  If the glass is broken and see “spilled ink” , we can judge preliminary there is something wrong with the LCD, and test for more result.

touch test)


3. Solution: From the above steps, we can judge which parts are wrong and get the solutions.

If the problem is in the glass, that’s simple to solve, just get a new glass and the phone can work again.

If the issues are on the touchscreen, pure change a new one is not realistic, Future Supplier can help you to refurbish, and you only need to pay for the processing fees. (Note: if your broken LCD is iPhone 6/6 Plus, we can convert it into iPhone 6S/6S Plus for you.)

screen separator

If you find it is the problem of the LCD, you need to consider to get a new LCD Assembly, but the broken LCD can send to Future Supplier for recycling.

Furthermore, we need to know the structure difference between OEM and Copy LCD, As following picture:



OEM LCD adopts In-cell technology, the touch sensor and glass is separate, even if the glass is broken, the touch function is not affected, that’s why the phone still work though the screen cracked.

Copy LCD adopts on-cell technology, the touch sensor and glass are stick together, if the glass is cracked, and touch function is affected.


Generally Speaking, pay attention and take care of your phone, no matter what technology the lcd adopts, you can not fall down the phone frequently. If it happens, Don’t panic. This article can help you and contact us:

Exposing Other Problems After iPhone 7’s Explosion?

The exploding Samsung Galaxy Note 7 has had its time. Is it the iPhone 7’s turn to take center stage? We hope that is not real.


What caused this iPhone 7 to catch fire is still unknown, but this is not the first time that an iPhone was involved in a fire or explosion incident. Let’s expect official explanation soon after.

After the new iPhone 7/ 7 Plus released, there also exist some other problems exposed by iPhone 7 owners. Let’s check how many problems are there which has been revealed yet?

Hissing noise

Some iPhone 7 owners in Facebook, Twitter and other social media revealed that there exists annoying current noises when they’re subjected to a heavy processor workload, such as a game. It’s not clear what the cause is — some suspect coil whine or similar electromagnetic effects, some thought it has something to do with RF transmitter or loudspeaker system but there’s no guarantee that these are the cases.

Lightning EarPods volume bug

Another issues iPhone has encountered is that some iPhone 7 users have found an annoying glitch with Lightning EarPods, it happens when you’ve left the EarPods plugged into the iPhone 7’s lightning port for a few minutes. Audios continue to play but you can’t adjust volume, activate siri or answer calls. It seems this phenomenon is random and intermittent. This problem has been confirmed by Apple, they declared that can be fixed by updating software.


No service when turn off airplane mode

Normally when you turn on the airplane mode, then you’ll lose all the wireless signals, and turn off airplane mode, everything needs to be back to normal. However, some users revealed that there is still no service when they switch off the airplane mode. For this problem, Apple has provide a solution, restart the phone. If that still not working, then they suggest people to reinsert the SIM card. However, that’s not convenient for most of us, after all, who would carry an eject pin with himself all the time?


AirPods radiation rumors

The new AirPods comes along with the iPhone 7/7 plus which has also attracted many focus by its impressive features and price. However, there are rumors that the new stuff may cause damages to our health because the headphones are transmitting very low intensity radio waves into our ears. An Apple spokesperson clarified: ‘Apple products are always designed and tested to meet or exceed all safety requirements.’ So what do you think of this new airpods?


Finger printer in Jet Black

Since iPhone 7/7 Plus has been on marketing, the new Jet black ones become the most popular choice for apple fans. However, the problem comes along, though adopting new technology, the jet black iPhone 7/7Plus still tends to be scratched, what’s more, many Jet Black iPhone 7 users complained that the phone body is pretty easy to get covered by the finger printers. And there is no efficient way to solve this problem, even Apple suggests people making their iPhone 7 wear a protective case.


iPhone 7 yellow screen problem

From the picture below, you can tell the differences between the iPhone screens. For this yellow screen phenomenon, people have different opinions, Luckily, the yellow screen can be distinguished only when you turn the screen to the highest brightness. Normally there is no big effect to your daily use.


So these problems are exposed mostly by users, anyway, we’re looking forward to seeing Apple helping iPhone users to solve these problems. If you find any other problems and solutions, welcome to share with us!

What Makes Waterproof Phone Free From Water Damages?


Speaking of waterproof cellphone, Sony may be the first name that comes into your mind. Nowadays more and more manufacturers are trying to make their phone waterproof, like Motorola and Samsung. As we know the new Samsung Galaxy Note 7 featuring the IP68 waterproof rating, even the iPhone 7 is waterproof. So how does a phone become waterproof and which part should be the most important in waterproof designs?


Generally, the common used waterproof materials are waterproof sealant tape, sealant rubber ring, waterproof membrane, Nano waterproof coating etc. Usually these parts like back cover, ear speaker, microphone, USB interface and side buttons are the most likely places to get involved with water. As to the inside, as long as the outside parts can be well protected from water, there is hardly chance for the inside parts get wet.

External Waterproofing

Like the gap between back shell/LCD screen and middle frame, usually there will be a strong sealant tape (as we called waterproof adhesive) fits tightly together. For example, when we disassemble the Samsung Galaxy Note 7 back glass or the AMOLED screen, we can see the strong adhesives adhered tightly to the back glass or middle frame which prevent the phone from water damages. Because of this strong adhesive, the teardown work could be harder, that’s the reason why most cellphone can’t be waterproof again when repaired by DIY repair work, the sealant tape adhesives needs to be sealed with professional skills.


As to ear speaker, microphone (parts with porosities), which needs the assistance of air to work together. So the high-density mesh waterproof membrane is designed to use in these parts. This waterproof membrane can only let the air and voice go through, the water molecules can’t pass through without high pressures. That’s how it prevents from water damages.


When it comes to the gap between the phone body and USB charging port, headphone jack or SIM card tray, these parts are often sealed with the sealant rubber ring.

ear-speaker-waterproof-membrane seal-rubber-and-water-resistant-screen

Galaxy Note 7 headphone jack rubber seal


Galaxy S5 SIM card tray rubber seal


As to volume & power button or home button parts, they are also prevent water from entering the mobile phone inside by means of waterproof membrane or sealant rubber ring.

Galaxy Note 7 side buttons watertight seal


Internal Waterproofing—mainboard

As to the core part of the mobile phone—the mainboard, the way to keep it away from water damage is covering the mainboard with the nano waterproof coating layer, once this layer has been applied to the motherboard, the ultra-thin nano protective film will be generated to prevent the contact between electronic components and water, thus, even though water seeped into the mainboard, still these electronic components on the mainboard will not be damaged. However covering the waterproof coating can be a tough and costing job for the cellphone manufacturers.


Through these analysis of waterproof cellphone above, we can see that waterproof design is not that difficult, the most used waterproof material are sealant tape, rubber seal ring, waterproof membrane and waterproof hydrophobic coating, sealing up the weak points where there is a possibility for water to enter with these waterproof materials can help your phone away from bad water damages. So if there is no such difficulties in waterproof design, why the waterproof function is not equipped with most of cellphones? Hence the main reason is that if the waterproof design has been added, the difficulty and steps for cellphone production will increase as well, and the defect rate may increase along with it. What’s more, there should be a very strict quality test before and after mass production, the cost increasing can be another big factor which affect the popularization of the waterproof mobile phone.


Also we should know that even though your cellphone featuring waterproof, you still need to take good care of it, even an IP 68 waterproof rating cellphone can be ruined by water damages which is not covered by the manufacturer warranty.

What is the Impact to Repair Shop If iPhone 7S Features OLED screen?

There are rumors that Apple is planning to equip its 2017 smartphones with OLED screen technology, despite previous speculation pointing to a 2018 switch from LCD.


According to the news from The Korean Herald, Samsung has signed a contract with Apple about supplying 100 million OLED screens in 2017. Another news revealing that LG has also added a product line for OLED screen, which will be put into production in early 2017. So in early 2017 or at the latest by 2018, we will see iPhone made of OLED screen.

iPhone 7S LCD

As for the influences to the mobile phone repair industry, let’s first take a look at the supply of the mobile phone repair parts market.

Take the most popular iPhone replacement screens for example, there’re 4 different types of sources;

1. The original replacement screen

The main sources for original LCD screen replacements are spare inventories from original manufacturers or defective parts from original assembly lines.

2. Refurbished LCD replacement screen

The majority of damaged screens are glass-only broken screens, while the LCD display and digitizer still work. To refurbish these screens with brand new glass replacements can make them back to life and market again.

3. Flex-assembled LCD replacement screen

Apart from the original LCD assembly replacements, some original spare or defective LCD displays are seeping into the market. And some small third-party manufacturers will purchase and turn them into final replacements by assembling with new glass lens, adhesives, digitizer frames, backlight films, LCD ICs etc.

4.OEM-Compliant LCD replacement screen

The OEM-complaint replacements showed up because of the imbalance between huge demands for replacements and few original stock in availability. Comparing with the original screens, OEM-complaint ones work but still need to be improved regarding the display effect and working stability.

iPhone 7 oem compliant lcd
Judge from the market demand, the original, refurbished and flex-assembled LCD screen, which uses the original LCD, are the most needed replacement in the market.

However, since last June, the original LCDs are more and more difficult to be obtained due to the strong control of original factories for the spare inventories and defective LCDs, which makes the original LCD price rises drastically and leads the repair shops and screen replacement suppliers into a dilemma. In order to meet the demands of these repair shops, the parts suppliers customized and ordered the LCDs from the Chinese factories, and assembled these China made LCD screens by third party manufacturers. Subject to cost competition, the repair shops have no choice but to purchase the China made LCD screen replacements instead.

In the long run, the price of original LCD screen will not decrease so much due to shortage of supply.

So what will it truly bring to repair shops when Apple starts using the OLED screen in iPhones?The OLED technologies, are basically monopolized by LG and Samsung while the LCD production technology are already quite mature in China (both in high, medium and low-level). Unfortunately the Chinese LCD screen manufacturers for the time being has no technical strength to produce the small size OLED screen replacements in bulk and high standards (Though TM and JDF’s OLED product lines are under construction and pre-production, there is still a long way to meet iPhone product’s standards). Besides, the 3D touch function of iPhone LCD screen assembly increases the technical difficulty of production. We have to admit that the China made OLED screen replacements can’t meet the demands of the market in short term.

iPhone 7 lcd

As for the third party repair shops, the refurbished LCD screen which comes from the glass-only broken LCD screen of customers, will be the major source of screen, and today is not the worst day for third party repair shops.

New Way to Refurbish Samsung S6 Edge/S7 Edge LCD Assembly

It is difficult and significant to refurbish S6 Edge/S7 Edge LCD digitizer assembly compared with S6 and S7 LCD, because the refurbishing technology and success rates are not mature and stable at present.

S6 Edge cracked screen

But we recently found a new way to increase product yield and the success rate for refurbishing S6/S7 Edge curved screen.

First of all, we need to know the difficulties to refurbish the curved display screen.

  1. Curved screen can not be directly operated at hot plate;
  2. After heating, cutting technique can not be used to separate LCD , or lcd leakage will appear;
  3. The cutting force is difficult to control which may result in LCD scrapped.

In consideration of those difficulties, we found new measures to refurbish the curved display screen, S6 Edge/S7 Edge. Six steps are needed as following:

1.Dismantle front housing: Put the lcd screen into the naphtha for 10 ~20 minutes. Use the card to separate the frame directed from the middle to the edge. Take good care of the flex cable in case of the damage in the process.

dismantle front housing

2. Dismantle Glass cover: Use a blade to open a small gap between the digitizer and glass, to make room for the card which will be used to separate the two in the freezer. Put the screen in the freezer for about 60 seconds. Then push the card into the gap. Please be aware that the lcd screen must be 100% attached to the sink bottom of the freezer, because only the bottom area can guarantee the lowest temperature of 140 degrees F. If the glass cover is broken, we need to start separating from the side where the glass damage is the smallest, and then to the rest gradually.

dismantle glass cover

3. Remove the excessive glue: We can use the # 833 glue to slowly remove it with the help of a plastic card. If the glue is very sticky and hard to be cleared, please cover a cleaning cloth with #833 glue onto the lcd to have the glue slowly dissolved.

Remove the excessive glue

4. Laminating OCA and New glass cover: Tear off the protective film and stick it to the other side of the OCA,This will make it more correctly to align the OCA to the glass. Place the front of the OCA to the same area on the glass, and laminate it with vacuum laminating machine for one minute.

5. Laminating LCD and Glass Cover: Wash the LCD again with naphtha(if conditions allow, you’d better clean it at clean room to avoid dust and impurities), then laminate the lcd and glass cover with Vacuum laminating machine.

lamination is finished

6. Vacuum removing bubble: After laminating the lcd, a few small bubbles will still exist, using vacuum remove bubble machine for about 15 minutes, then you get the fully good lcd assembly.

From the above six-step, refurbishing the curved lcd is not so difficult as imaginary, if your refurbishing equipment is complete, just do as the instructions, refurbishing S6 Edge/S7 Edge LCD screen is not far away.

Can Your OEM-Compliant iPhone 5S LCD Be Used for iPhone SE?

Since  we received the newly released iPhone SE , we did a thorough study in which parts that the iPhone 5S and iPhone SE share in common. Not surprisingly, many replacements parts of iPhone SE are compatible with iPhone 5S, their internal structure are almost the same. What excited us most is that they can totally share the same LCD screen and digitizer assembly, which with no doubts will reduce the inventory and supply chain integration pressures of repair shops. However, with the original LCD screen is getting more and more difficult to be obtained, most repair shops are using more replacements parts produced by third party manufacturer in China.

In order to figure out whether the iPhone 5S LCD screens produced by the third party manufacturer are compatible with iPhone SE or not, we did the following experiment in iPhone SE:
1.Types of surveyed LCD screen: We chose 4 different LCD screen made by Chinese LCD Screen manufacturers: TM, LT, JDF and In-cell.
2. Sample number: 20 for each kind
3. The test content: Display and touch function
And here are the results
iPhone se not compliant with iPhone 5s

What surprise us is that all of the China made LCDs can work well whether on display or touch function in iPhone 5S, however, when being used in iPhone SE, there are serious problems like shaking screen, black screen, Vertical lines on display (which just like you didn’t connect the LCD screen connectors well).

shaking screen of iphone se

Why these problems happened?
First thing we need to know: the sources and production process of the China made LCDs.

The TM/LT/JDF/In-cell LCDs assemblies in the market are not completely produced by the manufacturers themselves, they just provide the cut LCD screens, the rest processes are finished by the other third party manufacturers which also provide assemble the glass lens, digitizer frame, the LCD back plate shield and the LCD drive IC and other related small parts. It is not only the LCD itself which influences the display function, the compatibility between LCD drive IC and the motherboard is also another important involving factor. In order to save costs, pursue higher profits, these third party manufacturers are using OEM-compliant LCD drive IC, which just debugged with the compatibility of 5S’s motherboard, not with SE’s.

In order to verify our speculation, we did another experiment:
Sample LCD screen: 10 pieces LCD screen made by In-cell(with original LCD drive IC)
Sample device: iPhone SE
Test result: All 10 LCD screens are worked well, no shaking screen, no black screen nor vertical lines on display appeared.

Most China made LCDs are using the OEM-Compliant LCD driving IC at present. When replacing iPhone SE LCD screen with it, there is a big chance to encounter the phenomenon of shaking screen, black screen and vertical lines on display.

1. Original and brand new LCD screen would be your best choice when replacing iPhone SE LCD screen, if not, the assembled original screen and original-refurbished screen are second choices.
2. If you truly want cost-effective China made LCDs, seek for reliable suppliers who uses the original LCD drive IC.(That is very important)

Why Sony Z3 Series Front Housing Adhesive Should Be Heated Before Used?

Recently many videos about Sony Z3 front housing adhesive impressed us which showed the adhesive should be heated before used.  They said Sony Z3&Z5 series front housing adhesive are weak when they used, which caused problem when they assembled screen with frame. To explain this problem, we made a test and found some very important information.

For Sony Xperia Z3+ Front Housing Adhesive(1)
There are two types of front housing adhesive for Sony Z3/Z3Compact/Z3+, Z5/Z5Compact/Z5 Premium, one is original front housing adhesive, another is OEM compliant front housing adhesive. Let’s take Sony Z3 front housing adhesive for example. You will know the difference.

compare oem and oem-compliant

1. Material difference

z3 front housing adhesive compare

2. Quality difference

For non-original adhesive, there are different quality also as they are from different factories. So Future Supplier had tested many suppliers and would use the best source.

3. Usage difference

Step 1:
Clear up the residual gum on the screen &front housing with 90% Alcohol. Clear up the residual gum clean the lcd screen.



Step 2:
Peel off the films and put one side on the front housing then peel off final film. peel off the sticker

peel off the sticker

Heat up the front adhesive sticker for about 1 minute and make it stick tightly to the frame.

heat up

Step 3:
Original: Put the screen on and then put the whole front screen assembly with frame on the heating plate (80-100 centi degree for 5 second).

put screen on
Non-original: Put the screen on and press them with efforts.(No need to put it on the heating plate)

Last step:
Original: Press the screen with efforts and clean the screen surface.
Non-original: You could also use 3M reinforce to strengthen the stickiness before you put screen on.



So if Sony Z3 front housing adhesive you purchased is original, heat the item by heating plate before used, then it will work.
You will also notice the same situation would happen on Sony Z3 compact/Z3+, Z5/Z5 Compact/Z5 Premium. So the correct ways for you to use their front housing adhesives which are the same as Sony Z3.
