You might not realize it, but your phone screen has an "expiration date" just like food. With thousands of swipes every day, your screen is quietly aging.

A brand-new phone screen feels smooth as silk, but over time it becomes sticky and sluggish. This happens because:

• The oleophobic coating gradually wears off
• AMOLED screens may develop burn-in
• Touch responsiveness slows down

To extend your screen's lifespan:

✓ Clean with a soft microfiber cloth
✓ Avoid using your nails on the screen
✓ Don't use at maximum brightness for extended periods
✓ Keep away from high-temperature environments

How long have you been using your current screen? Maybe it's time to start taking better care of it!

1、 Understand the difference
In the field of mobile phone repair and maintenance, the terms "original screen" and "factory screen" are often heard, which sound similar but actually have significant differences.
Original screen "refers to a screen produced by an original equipment manufacturer (OEM), which is provided by the device manufacturer and therefore has high quality and consistency. However, they may not be produced on original equipment.Original screen "refers to a screen produced by an authorized manufacturer, usually on the equipment of the manufacturer, with high quality and consistent manufacturing standards.
2、 How to choose the appropriate screen
Choosing the right screen is crucial when you need to replace your phone screen. Here are some suggestions for selecting the correct screen:
1. Get to know your phone. It is very important to understand your phone brand, model, and screen size before purchasing any phone accessories.
2. Choose a screen of appropriate quality. Choose high-quality screens, purchase from mobile phone manufacturers or authorized service centers, and ensure they provide warranty and support.
3. Identify the screen. If you are unsure whether you have obtained an original screen or a factory screen, you can observe the screen features and display quality to make a judgment. Original screens may sometimes have minor flaws or defects, while factory screens typically do not experience such issues.
3、 Summary
When it is necessary to replace the phone screen, it is particularly important to understand the difference between "original screen" and "factory screen" and choose the correct screen. Although these terms sound similar, they have different meanings and uses. Choose a high-quality screen and purchase it from a mobile phone manufacturer or authorized service center to ensure that you will receive support and warranty.

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.

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!
