In this era when smartphones have become a necessity in our lives, a high-quality screen can indeed significantly improve the user experience. Faced with a wide range of screen types on the market, such as LCD, OLED, etc., how can we make a wise choice?


Analysis of mainstream screen types
‌1. LCD screen‌:
Light performance: using backlight technology, the light is uniform and soft, and there is basically no flicker problem
Eye protection advantage: especially suitable for users who are sensitive to the screen for long-term use
Service life: relatively long, low maintenance cost
Disadvantages: black display is not pure enough, and the overall power consumption is relatively high
2‌. OLED/AMOLED screen‌:
Display effect: strong color expression, high contrast, vivid picture
Functional features: support innovative technologies such as under-screen fingerprint
Energy consumption performance: more power-saving when displaying dark content
Usage suggestion: choose a model that supports DC dimming Can improve the flicker problem under low brightness



Key indicators for purchase

‌1. Resolution selection‌:
Basic needs: 1080P resolution can meet daily use
Advanced choice: If you pursue higher clarity, you can consider 2K or 4K screens
‌2. Refresh rate considerations‌:
Standard configuration: 60Hz refresh rate
Smooth experience: 90Hz or 120Hz can bring smoother operation experience
‌3. Brightness requirements‌:
Outdoor use: It is recommended to choose a high-brightness screen to ensure visibility in the sun



Master these purchase points, I believe that you will be able to find the screen configuration that best suits your needs the next time you change your phone. I don’t know what type of mobile phone screen you are using now? Are you satisfied with its performance?

The difference between the two



1. Thickness: LCD screens are thick and hard, and cannot be bent; OLED screens can be bent, making them softer and thinner. From a structural perspective, AMOLED thickness can be nearly 30% thinner than LCD.





2. Price: Due to the mature technology of LCD, LCD is cheaper in terms of price.



3. Service life: LCD screens use inorganic materials, while OLED screens use organic materials. OLED screens have a shorter service life than LCD screens.



4. Color expression: LCD emits light through backlight refraction, so when displaying black, there may be light leakage and whitening around the screen, making black more similar to gray. OLED can express colors through self emission, resulting in a more vivid and full display effect, but there is a risk of screen burn-in.

5. Energy consumption: The luminous principle of LCD is that the color filter film will cause a decrease in light efficiency. Some analyses suggest that the utilization rate of LCD for backlight brightness will not exceed 15%, and 85% of energy is wasted. Therefore, OLED is more energy-efficient than LCD.



LCD is never a slave



OLED screens are often referred to as "blind screens" due to the issue of screen flicker. When adjusting screen brightness, OLED screens use PWM dimming, which is commonly understood as turning on and off every second to control brightness. The brightness is adjusted by the proportion of screen on/off time within the interval.



As long as I light up and turn off quickly enough, my brain cannot feel that I am rapidly switching between light and light states. For some people who are sensitive to screen flicker, PWM dimming is particularly unfriendly to their eyes at low brightness, especially at night, which is why some people may feel obvious eye pain and soreness when using their phones at night.



However, many manufacturers later introduced DC modulation to solve the problem of screen flicker, but with it came the problems of screen burn-in and uneven brightness.



LCD enthusiasts are shouting: LCD will never be enslaved, because of the fatal problem of OLED screen flicker.

future trends



Although OLED has screen flicker issues, in daily use, the human eye cannot clearly perceive it. Only those who are very sensitive to screen flicker will truly feel discomfort.



OLED with greater power than excess has more advantages, such as better contrast, better black performance, wider color gamut, lighter, thinner, bendable, and so on. That's why mainstream flagship phones now choose OLED screens.

In the future, the development trend of mobile phones will also move towards full screen, curved/foldable screens, and under screen fingerprint and under screen cameras, and the position of OLED will not be shaken. LCD screens will be more commonly used in mid to low end smartphones due to their low cost and mature technology.



So, whether to choose LCD screen or OLED screen, Haoge has summarized their respective advantages and disadvantages for everyone. If you are particularly sensitive to screen flicker, it is recommended to choose LCD. In addition, choosing OLED screen can bring a better visual experience.

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.

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!
