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.

**1. OLED screen**



OLED screen, also known as organic light-emitting diode screen, is a self luminous screen that does not require a backlight source. OLED screens have advantages such as self illumination, high contrast, and vivid colors, and can also be made very thin, making them very popular in mobile phone design. However, OLED screens also have some drawbacks, such as relatively short lifespan and susceptibility to screen burn-in.

The working principle of OLED screens is to utilize the characteristic of organic materials emitting light under the action of current. When current passes through organic materials, the materials emit light, thereby achieving image display. Each pixel of an OLED screen emits light independently, allowing for high contrast and high saturation color display. Meanwhile, OLED screens also have the advantages of fast response speed and low power consumption, making them very suitable for displaying dynamic images and videos.

The advantages of OLED screens also include:

-Thin and light: OLED screens do not require a backlight and can be made very thin, making them very suitable for portable devices such as smartphones.

-High contrast: OLED screens have a very high contrast ratio, reaching 100000:1 or more, allowing them to display very deep black and bright colors.

-Wide viewing angle: OLED screens have a very wide viewing angle, reaching over 180 degrees, so the color and contrast of the image will not change when viewed from different angles.

The drawbacks of OLED screens include:

-Relatively short lifespan: The organic materials of OLED screens have a relatively short lifespan and are prone to screen burn-in, which means that when the same image is displayed for a long time, traces will be left on the screen.

-High cost: The production cost of OLED screens is relatively high, so the price is also relatively expensive.

-Insufficient brightness: OLED screens have relatively low brightness, which may make it difficult to see the screen content clearly in sunlight.



**2. LCD screen**



LCD screen, also known as liquid crystal display screen, is a type of screen that requires a backlight source. LCD screens have the advantages of low cost, high brightness, long lifespan, and also have good performance in color reproduction and contrast. However, LCD screens also have some drawbacks, such as relatively slow response speed and smaller viewing angles.

The working principle of LCD screens is to control the transmittance of light by utilizing the orientation changes of liquid crystal molecules under the action of an electric field. When an electric field acts on liquid crystal molecules, they undergo orientation changes, thereby altering the transmittance of light and achieving image display. The backlight source of LCD screens usually uses LED or CCFL (cold cathode fluorescent lamp), which can provide uniform brightness distribution.

The advantages of LCD screens include:

-Low cost: The production cost of LCD screens is relatively low, so the price is also relatively cheap.

-High brightness: LCD screens have relatively high brightness, and the screen content can be seen clearly in sunlight.

-Long lifespan: LCD screens have a relatively long lifespan and are less prone to screen burn-in.

The disadvantages of LCD screens include:

-Relatively slow response speed: LCD screens have a relatively slow response speed and may experience ghosting when displaying dynamic images.

-Small viewing angle: LCD screens have a relatively small viewing angle, and when viewed from different angles, the color and contrast of the image will change.

-Relatively low contrast: LCD screens have relatively low contrast and cannot display very deep black and bright colors.



**3. AMOLED screen**



AMOLED screen, also known as active matrix organic light-emitting diode screen, is a self luminous screen similar to OLED screen. AMOLED screens have the advantages of fast response speed, high contrast, vivid colors, and can also be made very thin, making them very popular in mobile phone design. However, AMOLED screens also have some drawbacks, such as relatively short lifespan and susceptibility to screen burn-in.

The working principle of AMOLED screens is to utilize the characteristic of organic materials emitting light under the action of current. When current passes through organic materials, the materials emit light, thereby achieving image display. Each pixel of an AMOLED screen emits light independently, allowing for high contrast and high saturation color display. Meanwhile, AMOLED screens also have the advantages of fast response speed and low power consumption, making them very suitable for displaying dynamic images and videos.

The advantages of AMOLED screens include:

-Fast response speed: AMOLED screens have a very fast response speed, reaching microsecond level, making them very smooth when displaying dynamic images.

-High contrast: AMOLED screens have a very high contrast ratio, reaching 100000:1 or more, allowing them to display very deep black and vibrant colors.

-Wide viewing angle: AMOLED screens have a very wide viewing angle, reaching over 180 degrees, so the color and contrast of the image will not change when viewed from different angles.

-Thin and light: AMOLED screens can be made very thin, making them very suitable for portable devices such as smartphones.

The drawbacks of AMOLED screens include:

-Relatively short lifespan: The organic materials of AMOLED screens have a relatively short lifespan and are prone to screen burn-in, which means that when the same image is displayed for a long time, traces will be left on the screen.

**4. TFT screen**



TFT screen, also known as thin-film transistor screen, is a type of screen that requires a backlight source. TFT screens have the advantages of fast response speed, high brightness, high contrast, and also have good performance in terms of viewing angle. However, TFT screens also have some drawbacks, such as inaccurate color reproduction and smaller viewing angles.

The working principle of TFT screen is to use thin film transistors (TFT) to control the brightness of each pixel. TFT is a semiconductor device that can control the brightness of pixels by changing the current. When current passes through TFT, TFT controls the brightness of pixels, thereby achieving image display. The backlight source of TFT screens usually uses LED or CCFL (cold cathode fluorescent lamp), which can provide uniform brightness distribution.

The advantages of TFT screens include:

-Fast response speed: TFT screens have a very fast response speed, reaching the millisecond level, making them very smooth when displaying dynamic images.

-High brightness: The TFT screen has relatively high brightness, and the screen content can also be seen clearly in sunlight.

-High contrast: TFT screens have relatively high contrast and can display very deep black and bright colors.

-Wide viewing angle: TFT screens have a relatively wide viewing angle, reaching over 160 degrees, so the color and contrast of the image will not change when viewed from different angles.

The disadvantages of TFT screens include:

-Color reproduction is not accurate enough: The color reproduction of TFT screens is not accurate enough, which may result in color cast.

-High power consumption: TFT screens have relatively high power consumption, which can affect the battery life of the phone.

-High cost: The production cost of TFT screens is relatively high, so the price is also relatively expensive.

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!
