The original innovator screen broken is not asking for help, self-help screen change so easy: mobile phone broken screen replacement program selection and change screen guide

First of all, I would like to affirm that I wrote this article not because I wanted to show how professional I was. On the contrary, I only love tossing. In fact, I also changed screen for the first time. Therefore, I would like to share with you the experience you have to deal with after the mobile phone has broken screens. This is exactly what happened to me and it can be considered as a way to let everyone know about screen change. There are a lot of professional video-changing teaching videos on the Internet, and there are all kinds of models. I believe that everyone can find the one they need.

I. Introduction

The mobile phone I now use is the first handset cool1 dual that Cooper launched after being acquired by LeTV. It was launched in August 2016. The hardware manufactured by Cool was preloaded with LeUI, and the purchase was sent to LeTV.

The reason why this mobile phone was purchased was that it used to be a cool god f2, and it was not broken in the past two years. It is only hoped that the new machine can play, and the old machine itself is still in good condition. Therefore, it is also more confident of Cool's quality; Secondly, it is because the founder of Cool1 Dual was hosted by Liu Jiangfeng, and he also served as CEO of Cool. He still believes in Liu's ability, and he is also optimistic about the development of Cool. The third is that this machine is designed to be pretty good, and the dual inside the name also reflects the phone is a dual camera as a selling point, but also want to try how LeUI. (Liu Jiangfeng is the former president of Huawei's glory. It can be said that this brand of glory was brought up by him. After leaving Huawei in early 15th, he said that he was going to start a business. The result turned around and went to Coolpad to be a CEO. No wonder someone said he left this position. Overdue may just be to circumvent the competition agreement.)

The mobile phone's promotional map is as follows, the picture comes from the official website publicity map:

The quality of the mobile phone is still very good, and the broken screen is not broken once it is broken, but it has really been thrown numerous times before it finally hangs. With a single point on the upper right corner, the momentary force causes the screen to crack, as shown below:

Here only the first half is taken. In fact, it starts from the upper left corner and spreads to the edges on the left and the bottom. This makes me worried about whether or not the entire screen will be broken, so I just want to change the screen. If the touch and display are not bad, or if it doesn't affect the use, I may be too lazy to change screens (after all, it's expensive and expensive).

If there are friends who have read my introduction to this phone, you may consider buying it from JD.com, LeSports.com, CoolPay.com, and Tmall.com. The initial price of the phone is 1099 yuan, and the current price is still this. However, when the double eleventh has a promotion to 899, so if you want a good price of friends but also pay attention to the price changes of major sites. The following is my purchase link from LeTV Mall:

It seems to be pulling too much. I'm sorry to say that it's a bit more broken. I'll start with the next question and say something about the screen.

To change the screen, we must first understand the composition of the mobile phone screen, in general, the mobile phone screen is divided into the inner screen and the outer screen, the inner screen is the display screen, if there is damage will appear abnormal display, for example, there is a color stripe or screen, some are not Display, color change, etc.; and the external screen is a touch screen, in general, the fragmentation of the external screen will often appear broken, and will not even affect the touch function, but the screen split into many blocks affect the viewing.

(Recall now that my mobile phone is only part of the external screen, and it has not been exploded. Why do I have to change one?)

Therefore, we found that after the phone suffered severe impact or extrusion damage to the screen, the first thing to check is whether the internal screen is broken or the external screen is broken, and then select the appropriate accessories for replacement. Of course, to say so, it is almost impossible for individuals to change their screens for themselves. Nowadays, most mobile phones use screen assemblies with both internal and external screens. When individuals want to change, they can only purchase screen assemblies for replacement. The author here is also a replacement assembly. If you want to change the external screen separately, you need a dedicated splitter to separate the internal and external screens. This will only be done if there is a special place to repair the mobile phone. It is also not guaranteed to be 100% successful and may fail. Of course, people on the Internet are said to be able to manually divide the screen. I feel it depends on the fate. The risk is too high. If you are not particularly strong in hands-on ability, and you don't want a friend on that phone, it is not recommended.

Take the author's cool1 dual as an example. After investigating the various channels, the screen replacement cost obtained by various methods is as follows:

1. Change the screen through the official after-sales outlets, only replace the assembly:

Cost: National uniform price of 368; Advantages: safe and reliable, ensure the original screen; Disadvantages: the price is too high

2. Replace the purchase assembly from one treasure:

Cost: Assembled price is ranging from 125-180 (There are a lot of merchants who sell, choose a suitable appraisal and price is good); Advantages: cheaper prices; Disadvantages: Although the screen change itself is simple, still need some operation, improper operation May fail to change the screen.

3. Purchase a separate external screen from a certain treasure to find a third-party repair shop with a splitter:

Cost: The external screen Taobao sells for 20 yuan (the seller is less), the repair shop manual fee 80 (asked several stores have cut down slightly reported this price, and then hard to cut it may not be able to be much cheaper), so the total The cost is almost 100, there are cost advantages out of the time: the cheapest price, do not have to give up the flaws of the intact screen: time-consuming and laborious, and the internal and external screen separation may fail

(There is no direct access to the repair shop directly for the external screen options, is cool1 dual or HUAWEI millet shipments such a particularly large machine, so each store will have their screen inventory, if they go there To set a screen on the Internet, we have to wait and the price will definitely increase again, so we recommend buying the screen. If it is a machine with a relatively large shipment like Huawei's Xiaomi, go to the store and change the price of the external screen should be in one hundred blocks. Around, we must cut a bargain.)

4. A treasure shop for repair outside the screen:

Cost: 98 yuan + logistics costs; advantages and disadvantages with Article 3

Computer Screen Protector,Screen Protector For Computer,Screen Protector,Best Computer Screen Protectors

Ultimately considering the price, practical ability, convenience, and success rate, I decided to choose the second option. I bought a piece of the assembly from a certain treasure and replaced it. I also sent tools and tutorial videos. So it is still not difficult to get started. However, friends with lesser hands-on ability and happen to use some popular models (namely, the repair shop will prepare corresponding screen inventory), you can consider the third scheme, go to the repair shop for external screen, and it should be more cost-effective and more secure. a little.

Should Xiaobian's request, to everyone to add the next search in the desired keyword of the screen, to the author's cool1 dual as an example, in the search field, enter "cool1 dual + screen", you can find a lot of baby information, of course, are mainly It is an assembly screen, and only two or three shops are required to buy an external screen. Because there are more merchants to sell, so the prices are more transparent, generally as long as not the price is too low and the product quality is similar, we can make a good choice under the comparison of the price and evaluation. The results of Taobao search are as follows:

The following official introduction of each step

Remarks: Some steps in this tutorial are specific to cool1 dual or mobile phones similar to the workmanship. The removal of other mobile phones please search for relevant video tutorials on the Internet. They are also easy to find and must be removed after confirmation.

The first step is to dismantle the screen. Nowadays, many mobile phone screens are glued together in a four-ply way. Therefore, using a hair dryer to heat around the screen will invalidate the glue and it will probably feel a bit hot. Then it's time. Use a crowbar or utility knife to separate the screen. In addition to the glue around, the screen and the motherboard are only connected by cables, and there are no other connections. Therefore, apart from the cables, there is no need to worry about breaking anything else.

The main problem to be noted in this step is that the disassembling process may damage the intact external screen. The specific reason I did not find it may be due to heating, or it may be due to the use of a utility knife to separate the screen during the process. It should not be planned. In short, after the demolition of the original intact internal screen also gave me a bad break, so the next step is to think that there is no way to change the screen, can only continue to do down.

To open the glue around the screen completely is what it looks like in the picture below.

It can be seen that there are only two cables connected between the screen and the motherboard. The smaller one on the left is the external screen line, the larger one on the right is the internal screen line, and the upper one is fixed with a fixed piece of screw. Details are as follows:

Use a screwdriver to unscrew the two screws and carefully pull the cable out. The old screen has nothing to do with the machine since then. Pay attention to the plug cable must be guaranteed when the screen is the state of the screen, the best condition to shut down, or easy to break through the motherboard's capacitance.

Oh, there's another thing. See the picture below. Above the screen, there is a handset. This is to be removed and placed in the same position on the new screen. All the uses of the old screen are over.

The new screen must not be used directly. After going through tests and confirming that everything is normal, it can be installed. Otherwise, according to the rules, the screen to be glued is not sold. Therefore, all problems must be clearly tested before the official installation.

(Note: Some of the contents of this section come from my purchase of the screen assembly of a certain treasure business, because in fact people sell something more valuable than you on this screen, I'm afraid there is something wrong with the transport, after sales trouble)

Start by opening the express package first. Conditionally try to open the package in front of the courier and check it to avoid any damage caused by transportation. Of course, under normal circumstances, there is still no problem, express packaging is very strict, cardboard boxes filled with plastic foam wrapped dozens of layers, generally do not have any problems. The check in this step is to check whether the screen is intact, whether it is broken, and whether the cable is intact.

Then the cable is connected to the main board of the machine for testing. Note that you must not apply glue first, or re-emphasize that all problems are checked before mounting. The two cables are simply snapped onto the machine and the screen is connected to the machine. The screen test is divided into four items, which are as follows:

【Screen effect】Tear off the screen protection first, observe the screen display effect after starting up, ensure the display screen is normal, no stripes, no damage, no leakage.

[Full-screen painting test] The input method for writing short messages is set to full-screen handwriting, and then full-screen painting ensures that there is no break in the screen.

[26-key test] Adjust the input method to a 26-character full keyboard test. Press each key one time to ensure normal operation.

[Function Key Test] Be sure to test the following three function keys, normally installed.

Generally speaking, if the screen has problems, it can be seen at once, and it cannot be said that the use of the screen must suddenly fail. Therefore, before the formal installation, it is necessary to do a good job of testing, which can prevent these problems and avoid the real problems of after-sales troubles.

The author encountered a problem in this step, that is, the screen is not bright after the screen cable is connected, but the internal screen behind the screen is able to emit light, as shown in the following figure. This made me once fear that he was not winning a bad screen, but fortunately after consulting with customer service, long press the power button for 10 seconds to restart the phone will be able to display properly. This may be because I am lazy to switch the screen for the sake of the screen, the screen is not activated, it is recommended that we have conditional or shutdown for screen, and when the plug cable must be information screen.

Finally, the official installation of the screen is actually very simple. We have tested the screen well. We only need to remove the screen and stick the double-sided tape on the back and forth. Correct! You are not mistaken, it is double-sided adhesive! In fact, the mobile phone screen is double-sided adhesive. This double-sided adhesive will give a little when buying the screen, far enough, as shown below:

The small black bar on the left side of the figure is a small piece of double-sided adhesive. The colloid is black, and it is not the same as the ones used by general stationery stores. However, the usage is the same. The adhesive is placed on the back and forth of the back of the screen. Be careful not to block the camera and photoreceptor. In fact, I only posted the upper and lower parts, the left and right sides were too narrow and the previous glue residue felt quite a bit, and there was no problem in fitting.

Next, connect the cable, fix the cable screws, and then remove the double-sided adhesive tape. Detach the screen and fix it by hand, and you're done.

Of course, our hand-glued glue may not be as tight as the factory produces. There is a small way to use a rubber band to wrap the phone around for a period of time to help fix it.

The final completed new screen is shown in the figure below. Replace the new film and display it perfectly:

At this point, the various steps of the screen change have already been completed. Although there are some minor setbacks in the middle, the overall situation is relatively smooth. Finally, the results of changing screens are also satisfactory.

Practice has proved that mobile phone screens do not have to be panic-stricken, and do not need to sell for hundreds of prices. As long as one hundred blocks, you can easily make screen changes yourself. Of course, if you want to change the screen only, you still have to go to a third-party repair company. That's not an easy task.

PS: Originally I only intended to casually say two sentences. The result was unknowingly coded on so much. This was late at night. Some mistakes were for the time being without modification, and they would be dealt with tomorrow. Everyone looks at my hard work, and I can say no.
