How to use a cell phone to test a cracked iphone LCD screen/display?

When you recycle or refurbish an iPhone cracked LCD screen, you need to check whether iPhone LCD display is good or bad. But how do you test a broken LCD screen? Many friends think the LCD is good, but when they sell the iPhone cracked screen in the market, the professional people may tell them that the LCD screen has many defects. It means a loss. So, we need to know how to test an iPhone LCD well.

There are two ways of testing the LCD screens. One way is using a tester; the other way is using an used iPhone to test. A tester is fast and simple, but it is not good enough to see the touchscreen fully. Using an iPhone to test the LCD screen is slow, but it is comprehensive.

Now I will share you our experience of how to use an iPhone to test a LCD screen. These steps are for Apple iPhone LCDs. But you can test Samsung, Sony or other brands phones according the same ways. You can see the picture about “iPhone + extended flex cable” as below:


We can sell you these flex cables, they are usually 3 to 4 USD depending on what models.


Now we start testing steps:

1)Check the screen apperance and connect the LCD screen to iPhone

When you start to test a LCD display, you need check to the cracked LCD apperance first. If the LCD or flex cable is broken very badly such as lack of some corner, you can judge that this LCD has no value. If you could decide it, please connect the LCD screen to an iPhone, turn on the LCD. If the screen could not be turned on when the connection of cables are good, it is considered as a  “black screen” and it is considered to has no value or little value.

2) test the LCD touch function

Press and hold an app icon and move from the ouside LCD to inside. Please see the video.

3) check the LCD if there are color spots, pressure spots

You need three background pictures, black, white and gray. And in the background you can see the details if the LCD display is defective.


below pictures are the examples which have defects:



4) test if the flex cable connecting is not good.

Push and pull the LCD slightly and watch the changing in the LCD. If the LCD display have changed, the connecting flex cable may not be good.

OK. Now you can confirm the LCD screen is good, if you could not see any defects after the steps above. Is it very easy? Hope this post can help you.

Do you want to refurbish your iPhone 5G/5S/5C/6G/6 plus LCD?

Date:25th,  August, 2015


Recently, The prices for iPhone 5G/5S/5C/6G/6 Plus have been raising in Shenzhen market, if you often order iPhone LCD’s from China, I think you should know that.


What causes the price rise so high? It’s said that the big factories don’t have LCD material to make the new iPhone LCD’s recently, so they don’t supply any new LCD to the market. The other people said that some big suppliers are controlling the prices for iPhone LCD’s. Any way, the market is lack of iPhone LCD’s right now.


The prices for the iPhone new LCD’s are so high, how do we save our money? I can give you a good idea. You can refurbish the cracked iPhone LCD’s, but they must be good LCD’s with broken glass. Right now, more and more overseas clients send their LCD’s to China to refurbish them. If you have one or more cell phone repair shops, I think you can collect a lot of cracked iPhone LCD’s. Of course, you can sell them in your local city or other country, but I think the value of refurbishing them is higher than that of selling them. This way it will save you money and you can get new LCD’s.


Our company has been doing this business for 5 years now, so we know well how to refurbish your iPhone 5G/5S/5C/6G/6 Plus LCD’s.

iPhone 6 Plus:If we just replace the top of glass, we charge you 90RMB/Piece. If we replace the top of glass as well as backlight, we charge you 125 RMB/Piece.

Shenzhen is an international makers’ center

There are so many supply chains and resources for markers in Shenzhen China. The requirements and demands from makers are also the enconomic engines for Shenzhen.

Huaqiangbei is one of the most important areas for makers, here you can find many parts and components in stock and you can get them immediately, by “immediately”I mean 2 to 20 minutes, the lead time is very important for prototyping, and the makers need to do so many experiments before the product is finalized, lead time for parts is very important for product development process, if you are an maker, I am sure that you know this better than we do, and secondly, most of the parts you need are from a small place, you will be able to talk to 20 to 30 different suppliers in one day. Most of the suppliers have some presence (booth or office) in Huaqiang Bei, and their factories might be quite far from here, because Huaqiang bei is very crowded, the space here is too expensive for a factory, and their factories need to be located 1 to 2 hour drive from the city area.

Nowadays, Huaqiangbei is still very good in business, and online Huaqiang bei seems to be very important too, and a lot of makers will go to Taobao to see what they need as well, and it takes one or two days before you can get it.

There are also many plastic and sheet metal factories in the surban areas of Shenzhen, as well as PCB and PCBA houses, the packaging and printing services are also available and easy to get.

Where are the markers located in Shenzhen? They are everywhere in Shenzhen, but the density of Shenzhen markers in Chegongmiao(Cyber Park) and High Tech Park is very high.

How can the makers get paid by the hard work they do?

There are so many trading companies in Shenzhen who can produce and sell your products to other cities in Shenzhen or oveaseas market, we call these trading companies “integrators” they take your design and have the parts manufactured in a large scale, and assemble and test the products on their own factory, and most importantly, they have a good team of sales people, your jobs will be well paid off by the PCBA you build for them, and they will call you the “solution companies” from who they can pick a good design for the market.

Why did Shenzhen become a makers’ city, one of the reasons is that Shenzhen a city of immigrants, many wel-educated persons like the ones with PHD will come to Shenzhen for jobs, it is quite easy for R&D companies to hire talent people here.

What are we doing here?

We are helping the international makers from the English-speaking countries take the advantages of Shenzhen Makers’ resources and supply chains here in Huaqiang Bei, Shenzhen China. There are many young people who speak good English come to Shenzhen for jobs, and we just train them with some techincal knowledges and they can help you a lot.
