1、 Original screen
Original screen refers to a screen produced by a mobile phone manufacturer that is identical to the original screen of the phone. The advantage of this screen is its superior quality and good compatibility with other parts of the phone, ensuring the best display effect and user experience. However, the price of original screens is usually higher due to their production costs and strict quality control. If your phone is still under warranty or you have high demands for screen quality, choosing an original screen is a good choice.

2、 OEM Screen
OEM (Original Equipment Manufacturer) screens are screens produced by partners of mobile phone manufacturers, with similar quality to original screens but usually at a more affordable price. The production process of OEM screens also follows strict standards, so their display effect and service life can be guaranteed. If your budget is limited but you want to get a user experience close to the original screen, then OEM screens are a cost-effective choice.
3、 Compatible with screens
Compatible screens are screens produced by third-party manufacturers, designed to be compatible with multiple phone models. The price of this type of screen is usually lower, but the quality and display effect may vary depending on the manufacturer. When choosing a compatible screen, it is recommended to carefully compare products from different brands and models to ensure that they meet your usage needs. Although screen compatibility may pose certain risks, it is still a viable option if you do not have high requirements for your phone screen or have a very limited budget.

4、 Press fit screenPress fit screen is a type of screen that combines a display screen and a touch screen. The advantage of this screen is that it is reasonably priced, and the display effect and user experience are relatively good. However, the compatibility and stability of laminated screens may not be as good as original or OEM screens, so careful consideration is needed when choosing. If your phone model is relatively rare, or if you do not have high requirements for the display effect and stability of the screen, then pressing the screen may be a suitable choice.
When choosing a mobile phone screen, in addition to considering the screen type and price, it is also necessary to consider the convenience of installation and maintenance. If you do not have the relevant technical knowledge, it is recommended to seek the help of professionals to ensure a smooth screen replacement process.

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



External screen broken: It's just that the glass screen of the external screen is broken, but the touch and display are normal. In this case, only the outer glass needs to be replaced, that is, only the external screen needs to be replaced.



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.

Preliminary Exploration of ProMotion Technology: The Secret of Adaptive Refresh Rate


ProMotion， This name itself contains the dual meanings of "professional" and "dynamic", indicating a major innovation in Apple's screen display technology. In short, ProMotion technology is a mechanism that can automatically adjust the screen refresh rate based on the current display content, with refresh rates ranging from a minimum of 10Hz to a maximum of 120Hz. This means that when you swipe the screen to browse web pages, play games, or watch high frame rate videos, the screen can present incredibly smooth visual effects with a refresh rate of up to 120Hz; When displaying statically or performing low-intensity operations, such as reading e-books, viewing photos, or in standby mode, the screen will lower the refresh rate to a more suitable level to save power.



Why choose adaptive refresh rate?


The reason why Apple introduced adaptive refresh rate technology in the iPhone 13 Pro series is due to profound considerations and user demand insights.



Improving user experience: Firstly, a high refresh rate screen can bring a smoother visual experience. For gamers, a high refresh rate of 120Hz means lower latency and finer transitions, taking the gaming experience to the next level. For daily users, whether sliding the screen, scrolling through web pages, or switching applications, they can feel an unprecedented sense of smoothness. However, if the phone always maintains a 120Hz refresh rate, it will not only consume a lot of electricity, but may also cause problems such as device overheating due to unnecessary performance output, affecting the overall user experience.


Optimizing energy management: As stated by Apple, one of the core advantages of adaptive refresh rate is its excellent energy management capabilities. Mobile screens are one of the largest energy sources in smartphones, especially when the brightness is high and the refresh rate is fixed at a high level. Through ProMotion technology, the iPhone 13 Pro series can dynamically adjust the refresh rate according to actual needs, effectively avoiding unnecessary energy waste. For example, when users are still viewing pictures or documents, the screen refresh rate can be reduced to 10Hz or even lower, significantly reducing battery consumption and extending battery life. This is undoubtedly a huge blessing for users who frequently go out and have high requirements for mobile phone battery life.


The combination of intelligence and efficiency: The implementation of ProMotion technology relies on Apple's powerful hardware and software integration capabilities. It requires seamless collaboration between screen driver chips, operating systems, and various applications to ensure real-time and accurate refresh rate adjustments. This intelligent adjustment mechanism not only reflects Apple's technological innovation, but also its commitment to pursuing the ultimate user experience. The algorithm predicts the user's behavior and adjusts the refresh rate in advance, so that each screen refresh is just right, which not only ensures the smoothness of visual effects, but also realizes the efficient use of energy.


Challenges and Solutions Behind Technology


Implementing adaptive refresh rate is not an easy task, as it requires the phone to find a perfect balance between hardware design, software development, and user experience. Apple has invested a significant amount of research and development resources in this regard, overcoming multiple technical challenges



Hardware upgrade: The iPhone 13 Pro series is equipped with more advanced display driver chips, which have stronger data processing capabilities and lower power consumption, providing a hardware foundation for fast and accurate refresh rate adjustment.
Software optimization: The iOS system has been deeply optimized to ensure that the system and third-party applications can fully utilize the advantages of ProMotion technology. Developers need to update their applications to adapt to display effects at different refresh rates, which requires Apple to provide detailed development guidelines and technical support.


User experience considerations: When designing ProMotion technology, Apple fully considered the differences in user perception. For example, the change in refresh rate between fast and slow swiping needs to be smooth enough to avoid giving users a sense of abruptness. This requires fine tuning and extensive user testing.


Impact on the industry and future prospects


Apple's introduction of ProMotion technology in the iPhone 13 Pro series not only enhances the competitiveness of its own products, but also has a profound impact on the entire smartphone industry. On the one hand, it has promoted the innovation of screen technology, prompting other manufacturers to accelerate their research and development pace in adaptive refresh rate technology; On the other hand, it has also raised consumers' expectations for the refresh rate of mobile phone screens, making high refresh rate and adaptive adjustment a standard feature of high-end smartphones.



Looking ahead to the future, with the continuous advancement of technology, adaptive refresh rate technology will become more mature and its application scenarios will become more extensive. For example, combined with AI and machine learning technology, mobile phones can more intelligently predict the user's next operation, adjust the refresh rate in advance, and further improve the user experience. Meanwhile, with the popularization of technologies such as 5G and AR/VR, adaptive refresh rates will leverage their unique advantages in more fields, bringing unprecedented interactive experiences to users.



In short, the ProMotion adaptive refresh rate technology in the Apple iPhone 13 Pro series is another important milestone for Apple in pursuing the ultimate user experience. It not only demonstrates Apple's leading position in technological innovation, but also sets a new benchmark for the entire smartphone industry, indicating the direction of future smartphone screen technology development.

Don't panic, the first step in self-study is to "line out" the screen

'Screen out' often means that the internal screen is damaged, so it's better to do it yourself instead of wasting money. Taking S15Pro as an example, the entire screen replacement process is broken down into 7 key nodes, each step accompanied by real-life photos, and following along can save a lot of maintenance costs.

02
Removing the back cover: The glass material needs to be 'translated'

2.1 ◇ First, cut open the double-sided tape, and then lift the cover in parallel
Lightly scratch along the border with a thin card, loosen the double-sided tape completely, and then move it as a whole. Avoid breaking it hard at 90 °, otherwise the back cover will instantly break into a "puzzle".



2.2 ◇ Remove the protective cover and battery
After removing the back cover, unscrew all the fixing screws around the body without missing a single screw; After removing the protective cover, disconnect the battery and power off the motherboard to avoid short circuits during installation.

03
Take the small board: first disconnect the cable and then take the screw

3.1 ◇ Loosen the display cable and charging port
Gently loosen the speaker and display cable interface, and there is also a straight screw on the top of the small board. After removing it, all cables can be pulled out.

3.2 ◇ Remove the card tray and protect the red dust-proof adhesive
Use tweezers to grip the card holder and gently shake it out; Use a leaf shaped pick to lift the small red leather circle next to it to prevent it from hooking onto the wiring when disassembling the screen.

04
Dismantling old screen: Blade+8+1 combination method

4.1 ◇ Cut open the sealant and apply 8+1 drops of solubilizing aid
Stick the blade tightly around the screen, cut off the sealant first, and then drip a small amount of 8+1 solvent to soften the glue for easy separation.

4.2 ◇ Card stitching, slow work produces fine work
The nail is stuck in the gap, and the card is slowly pushed along the edge. After all the double-sided tape is scraped loose, the entire screen can be removed.

05
Clean up residual adhesive and apply UV glue, and apply sealant to the middle frame

5.1 ◇ Special UV double-sided adhesive for cranks is put into use
Clean up all the old adhesive on the middle frame, apply UV double-sided adhesive specifically for the crankshaft, and apply a circle of sealant around the edges. The amount should be small rather than large - if the adhesive seeps out, it will create bubbles on the new screen.

5.2 ◇ Installing a new screen: align first and then press down
After inserting the cable and aligning the top, gently press down to ensure that the double-sided tape is fully adhered to the middle frame; Push on the battery and perform a power on self-test. If the touch and display are normal, proceed to the next step.

06
Reinstall the small board: plug the charging port first

Before putting the small board back in, first insert the charging port into the hole and fix it, then fasten all the cables in sequence, and finally reinstall the battery - the appearance of the startup logo indicates that the hardware is ready.



07
Upper protective cover, rear cover, and sealant

7.1 ◇ Tighten all screws in place
The speaker, charging port, and small board screws have all been reset; Clean up the residual adhesive on the protective cover and back cover, and then apply special sealant.

7.2 ◇ Cover and flatten, installation completed
Align the back cover with the buckle and lightly press it to fit. If the fingerprint and power button rebound normally, it means the whole machine has been restored. Power on test of various functions, no "wires" on the screen, sensitive touch, normal sound - great success!
