1. Methods for repairing mobile phone screens



1. Replace the outer screen (press screen) using equipment



Screen pressing is a common method for repairing broken mobile phone screens, primarily targeting repairs to the outer glass layer of the screen. Since it involves repairing the outer screen, the inner screen of your phone must be intact before this method can be applied. Screen pressing involves reattaching the new outer glass layer and display layer together, and then using professional equipment to press them together, ensuring they are tightly combined. The advantage of this method is that the repair cost is relatively low, and once repaired, it will not affect other functions of the phone.




However, it should be noted that screen pressing requires professional equipment and technology, which cannot be operated by ordinary repair shops, and it is also impossible to press the screen by oneself.





2. Replace the entire screen



If our phone screen is severely damaged and the internal screen is already damaged (screen display is abnormal, screen leakage, lines, black screen), then we need to consider replacing the screen.



Screen replacement is the process of removing the entire screen and replacing it with a new one. The advantage of this method is that it can completely solve the problem, but the price of the original screen is relatively high, and reliable repairers need to be found to ensure the quality of the screen.



2、 The price for changing the screen

The price of screen replacement varies depending on the brand, model, and repair method. Generally speaking, if only the external screen is damaged, we only need to find a professional repair shop to replace the external screen.
We are a professional wholesale company for various mobile phone screens and accessories, with over 10 years of one-stop procurement services for mobile phone accessories. We offer affordable prices, reliable quality, and guaranteed after-sales service. Please feel free to contact us！





If the internal screen is damaged, replacing the original screen may be more expensive. If you have high requirements, you can directly replace it with an original screen assembly. If the requirements are not very high, you can replace it with a brand screen assembly. If it is only a spare machine or just wants to export data, you can directly replace it with an assembled screen.





In addition, it is recommended to choose to have your phone screen repaired in store or by mail. Some home repair and screen replacement services often use an assembled screen to replace your original screen, especially if your phone only has a broken external screen. When replacing a phone screen, don't just look at the price. The price of replacing the external screen is closely related to the repair techniques of the technician. Some cheap repair shops have many tricks for replacing the external screen, such as not bearing the risk of the internal screen, which will ultimately lead to the price of repairing the screen increasing several times. The same goes for replacing the screen assembly. There are assembled screens, branded screens, press fit screens, face change screens, original disassembled screens, original touch screen replacement, screen replacement, and so on in the market. Anyway, remember that you get what you pay for. When repairing a screen, try to go to a store that only does repairs. For those who are not familiar with screens, please contact me.

In summary, if your phone screen is damaged and only the external screen is broken, we only need to replace the external screen.

It is necessary for us to learn how to distinguish between external and internal screen issues.

Internal screen malfunction: insensitive touch or screen jumping;



The display is also incomplete, with blackened and yellowed parts on the screen, indicating liquid leakage from the LCD screen; Horizontal and vertical lines are all signs of a broken display screen and require replacement of the inner screen, which is the screen assembly;



If your phone accidentally breaks, we suggest you choose our screen. We offer various types of phone screens, including incell, OLED, LCD, reliable quality, easy installation, reasonable price, and after-sales guarantee.

1、 What is OLED flexible straight screen?



To understand the difference between the two, one must first clarify what OLED is. Simply put, OLED uses a very thin organic material coating, which can achieve self illumination without the need for backlighting. It can be understood as OLED being composed of countless "small light bulbs". But whether it's a flexible screen or a hard screen, the materials used are the same. The main difference between them is the substrate material, which is the material supporting the OLED.



Flexible screens generally use PI and other flexible materials as substrate materials

Hard screens generally use hard materials such as glass as substrate materials



What exactly is a flexible straight screen? To put it bluntly, it's just about installing OLED flexible screens into straight screen phones.





2、 What are the benefits of using a flexible straight screen?



1. Due to the use of flexible materials as substrates, flexible screens have thinner screen thickness and lighter weight, which reduces the overall thickness, size, and weight of the phone. The thickness of mobile phones with large batteries/ultra fast charging like the K50 series is extremely terrifying, and using a hard screen will make the feel even more uncomfortable.



2. Due to its softness, flexible screens will have greater improvements in screen packaging technology. The use of COP packaging technology can make the black edge of the phone chin smaller, resulting in a better phone experience.



3. Flexible screens have a soft constitution, which can better protect the screen in the event of a phone falling or bending. In the event of damage to the external screen, a flexible screen can provide greater protection from the impact.

On Samsung OLED screens, rainbow patterns may appear on hard screens. However, many netizens have found that Samsung's flexible screen does not have this problem. This can also be considered a special place.





3、 Why didn't straight screen phones use flexible screens in the beginning?



To put it simply, it's still a matter of cost. In the past few years, the cost price of flexible screens was several times higher than that of hard screens, and COP packaging technology is also a high cost and low yield technology. In this way, the cost price will rise sharply.

Summary: The difference between mobile OLED flexible screens and hard screens lies in the substrate material used for the screen. And the flexible straight screen is actually to put the flexible screen into a straight screen phone for use. Flexible screens have thinner thickness, lighter weight, and better drop resistance. When choosing a mobile phone, it is better to choose a flexible screen.

First determine the type of fault

Fixed position color stripes/lines with broken inner screen, loose or aged wiring, lightly press screen edges for testing, backup data for repair

Full screen flashing/jumping stripe display driver failure, motherboard issue. Restart the phone to restore factory settings

Touch failure+striped touch screen damage or cable breakage, immediately stop using to avoid further damage

Possible self-study steps (at your own risk)

1. Eliminate software issues

Force restart of phone:

Huawei/Honor: Press and hold the power button for more than 10 seconds.

Xiaomi/Redmi: Power button+volume up button for 10 seconds.

IPhone: Quickly press Volume+, Volume -, and then long press the power button until the Apple logo appears.

Restore factory settings (data will be cleared):
Enter the system recovery mode (with different combinations of buttons for each brand) and select 'Clear Data'.



2. Check physical connections (for users with strong hands-on abilities only)

Disassemble the machine and re plug and unplug the ribbon cable (requires a screwdriver and pry bar):

After shutting down, remove the back cover (search for the corresponding disassembly video for the model).

Find the screen ribbon cable (usually located at the top of the motherboard), disconnect it, and then re fasten it.
⚠️ Risk: Improper operation may damage other components!

3. Temporary relief of display issues

Lightly press the edge of the screen: If the stripes change with pressing, it may be due to poor contact of the ribbon cable. You can try pressing the edge of the screen lightly for 12 hours (non permanent repair) with a book.

Do not attempt ineffective/dangerous operations

Heat the screen with a hair dryer (which may exacerbate delamination).

Freezing mobile phones (condensation water can corrode circuits).

Using the 'Screen Repair App' (purely false advertising, hardware issues cannot be fixed by software).

Ultimate solution official repair:

After sales replacement of screen assemblies for brands such as Huawei, Xiaomi, and Apple (priced at 300-1500 yuan, but with guaranteed quality).

Prioritize booking through official websites (such as Huawei services, Apple support).

Third party repair: Choose a store with good reputation and require the use of original or high imitation screens (lower price but higher risk).

Use a phone case and tempered glass film.

Avoid putting your phone under pressure (such as sitting in a pocket), high temperatures, or humid environments.

Regularly backup data to prevent sudden screen failure and data loss.

If the screen stripes are accompanied by touch failure or worsening diffusion, please stop using them immediately and send them for repair to avoid damaging the motherboard!

Why is it so expensive to replace a phone screen?The reason why mobile phone screens are expensive lies primarily in their complex composition. A complete mobile phone screen typically consists of an outer screen (touch screen), an inner screen (display screen), and an adhesive layer in between.When a mobile phone screen is shattered, it could be due to a cracked outer screen or simultaneous damage to both the outer and inner screens. Therefore, during the repair process, it is often necessary to replace both parts simultaneously. This not only increases the complexity of the repair but also raises the repair cost.Moreover, with the continuous development of mobile phone technology, the composition and structure of mobile phone screens are also constantly being updated and upgraded. The emergence of these new technologies may also lead to an increase in the cost of repairing mobile phone screens.In addition, apart from the cost of the phone screen itself, the technical cost of replacing a phone screen is also significant. This is because the connection between the screen and the motherboard has become increasingly precise, and even the slightest mistake can damage other components.Therefore, the cost of repairing a screen is high due to the nature of the phone screen itself and the technical difficulty of the repair process.
