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. We can provide wholesale and after-sales services for various screens。Tina WhatsApp:+86 13824303378





In summary, if your phone screen is damaged and only the external screen is broken, we only need to replace the external screen. If the internal screen is damaged, we need to replace the entire screen assembly. We can choose the appropriate repair method according to our own situation. At the same time, when choosing a repair shop, it is necessary to choose a reliable merchant to ensure the quality and effectiveness of the repair.

LCD Screen Era: Foundation and Brilliance
Technical principles and characteristics
LCD (Liquid Crystal Display) technology is an important milestone in the development of mobile phone screens. Its working principle is based on the electro-optic effect of liquid crystals, which displays images by changing the passage of light through the arrangement of liquid crystal molecules. LCD screens typically consist of a backlight, polarizing film, liquid crystal layer, and color filters. The backlight provides uniform light, the polarizer controls the direction of light passing through, the liquid crystal layer changes the molecular arrangement under the action of an electric field, and the color filter converts the passing light into the three primary colors of red, green, and blue, thereby forming a color image.LCD screens have the advantages of low cost, stable display, high color reproduction, large viewing angle, and relatively low power consumption. In the early mobile phone market, LCD screens became the mainstream screen technology due to their mature technology and wide applicability. For example, TFT-LCD (Thin Film Transistor Liquid Crystal Display) became popular in the early 21st century and gradually became the mainstream display technology for mobile devices, providing users with clear and stable image display.
Market Applications and Limitations
In the era of LCD screens, many well-known mobile phone brands have adopted this technology. The classic models launched by established mobile phone manufacturers such as Nokia and Motorola were mostly equipped with LCD screens, meeting the basic display function needs of users at that time. However, LCD screens also have some shortcomings. Its response speed is relatively slow, and it is prone to dragging and ghosting, which is particularly evident when watching high-speed moving images. In addition, LCD screens require backlight modules to illuminate the screen, resulting in relatively high power consumption, and the black color performance is not pure enough, with low contrast.

The Rise of OLED Screens: Innovation and Breakthrough
Technical principles and advantages
OLED (Organic Light Emitting Diode) screens are a major innovation in mobile phone screen technology. Unlike LCD screens, OLED screens use self luminous technology, where each pixel can independently emit light without the need for a backlight source. The basic structure of OLED screens consists of several thin films, including an anode, a cathode, and an organic material layer located between the two. When current passes through, electrons and holes in the organic material layer combine to produce an excited state. When the excited state returns to the ground state, light is emitted.
OLED screens have many advantages. Firstly, its vibrant colors and high contrast can present more realistic and vivid images. Due to each pixel emitting light independently, it can truly turn off when displaying black, achieving almost infinite contrast. Secondly, OLED screens have faster response times and smoother visual effects, which can effectively reduce ghosting and residual effects. In addition, OLED screens also have the characteristics of being lightweight, bendable, and foldable, providing more possibilities for the appearance design of mobile phones.
Market Development and Trends

With the increasing demand of consumers for the display effect and appearance design of mobile phone screens, OLED screens have gradually become the standard configuration of high-end mobile phones. Apple, Samsung and other mobile phone brands have adopted OLED screens in their flagship models, driving the rapid development of the OLED screen market. According to Omdia's latest OLED Display Panel Market Tracking Report, smartphone AMOLED display panel shipments are expected to continue to grow in 2024, surpassing TFT LCD shipments for the first time. This growth trend is mainly driven by the strong demand for flexible AMOLED displays in the market.
In the OLED screen market, the performance of flexible AMOLED displays is particularly outstanding. Starting from the second half of 2022, Chinese display panel manufacturers have significantly reduced the manufacturing cost of flexible AMOLED panels, driving major smartphone original equipment manufacturers (OEMs) to upgrade mid-range smartphone screens from traditional rigid AMOLED and LTPS TFT LCD panels to flexible AMOLED panels. The trend of replacing this display technology will further accelerate in 2024, increasing the market share of flexible AMOLED from 28% of the total smartphone display panel market in 2022 to 40% in 2024.
Comparative analysis of LCD and OLED screens
Display effect
In terms of display performance, OLED screens have significant advantages. Its color vividness, contrast, and viewing angle are superior to LCD screens. OLED screens can present richer colors and deeper black, making images more realistic and vivid. LCD screens, on the other hand, have relatively weak color saturation and contrast, and their black color performance is not pure enough, making them prone to light leakage when displaying dark scenes.
power consumption
Due to the self luminous technology used in OLED screens, each pixel emits light independently and can be turned off when displaying black, resulting in relatively low power consumption. LCD screens require continuous operation of the backlight module, which requires a certain amount of power to maintain the backlight even when displaying black, resulting in relatively high power consumption. In practical use, phones equipped with OLED screens usually perform better in terms of battery life.
Cost and lifespan
LCD screen technology is mature and the manufacturing cost is relatively low, so it still has a certain competitiveness in the mid to low end mobile phone market. The manufacturing cost of OLED screens is relatively high, resulting in higher prices for smartphones equipped with OLED screens. In addition, the organic materials of OLED screens have a relatively short lifespan and are prone to aging and screen burn-in, which is also a challenge they face.
Application scenarios
LCD screens are suitable for the mid to low end mobile phone market that is cost sensitive and does not require high display performance, as well as certain specific application scenarios that do not require high power consumption. OLED screens are more suitable for the high-end mobile phone market, meeting consumers' pursuit of high-quality display effects and personalized appearance design. At the same time, the bendable and foldable characteristics of OLED screens also provide more possibilities for the design innovation of future mobile phones.


Outlook for Future Mobile Screen Technology
Exploration of Emerging Technologies
In addition to LCD and OLED screen technologies, emerging screen technologies such as Mini LED and Micro LED are also constantly developing. Mini LED achieves higher brightness and more precise light control effect by reducing the size of LED beads; Micro LED, on the other hand, designs the LED structure into a tiny size, achieving higher pixel density and finer image display effects. However, these emerging technologies are still in the early stages of development and face some technical challenges, such as the relatively complex backlight design of Mini LED, which requires precise control of the luminous effect of each LED bead; Micro LED is facing technological challenges such as chip manufacturing and mass transfer.
Combining with cutting-edge technology
In the future, mobile screen technology will be deeply integrated with cutting-edge technologies such as 5G and AI. The high-speed and stable transmission of 5G networks will bring higher resolution and refresh rate content display to mobile phone screens, enhancing users' visual experience. AI technology can achieve intelligent optimization of screen display effects, automatically adjusting parameters such as brightness, color, and contrast of the screen according to different usage scenarios and user needs, providing more personalized display effects.

1、 The main types of mobile phone screens

At present, the mainstream mobile phone screens are mainly divided into two categories: LCD (liquid crystal screen) and OLED (organic light-emitting diode screen), and OLED screens have derived various technical solutions such as AMOLED, LTPO, Micro LED, etc.

1. LCD screen: classic and durable, with realistic colors

LCD (Liquid Crystal Display), also known as liquid crystal display screen, works by providing light source through the backlight layer, and then controlling the degree of light passing through through the rotation of liquid crystal molecules to display different colors.

Features:

✅ Natural color: Due to the native color of LCD screens, it is suitable for users who like realistic display effects.

✅ Good eye protection effect: LCD screens do not experience the common "flicker" problem of OLED screens, making them more eye friendly.

✅ Long lifespan: LCD screens are not prone to burn-in (there will be no residual images after long-term use).

❌ Low contrast: Due to the dependence of LCD on backlight, it cannot display pure black, and black often appears grayish.

❌ High power consumption: The backlight layer is always on, even if the black part is displayed, it is still consuming power.

❌ Difficult to make very thin: LCD screens have a large thickness, which is not conducive to ultra-thin phone design.

Common LCD screen types:

IPS LCD: With a large viewing angle and excellent color performance, it is commonly used in mid-range models.

TFT LCD: outdated technology with light colors and high energy consumption, has gradually been phased out.

Suitable for:

✅ People who use mobile phones for a long time (less flicker, better eye protection)

✅ Users who prefer natural colors (avoid oversaturated colors)

✅ Users with limited budget (LCD screen costs are relatively low)

Representative models: iPhone 11, iPhone SE 3, Redmi Note 12



2. OLED screen: vibrant colors, high contrast

OLED (Organic Light Emitting Diode) screens are composed of self luminous pixels, each of which can emit light independently without the need for a backlight layer, thus achieving pure black display and high contrast.

Features:

✅ Colorful: OLED screens have a wider color gamut and more vibrant display effects.

✅ High contrast: It can present true black and display more vividly.

✅ Lower energy consumption: OLED screens can turn off pixels when displaying black areas, reducing power consumption (but higher power consumption when displaying white).

✅ The screen can be made thinner and more flexible, which is beneficial for foldable and curved screen designs.

❌ Easy screen burn-in: Long term fixed display of a certain screen may cause ghosting (such as navigation bar, status bar).

❌ Strobe issue: OLED screens typically use PWM dimming, which may cause eye fatigue at low brightness.

❌ High cost: High quality OLED screens are expensive and are usually used for mid to high end models.

Common OLED screen technologies:

AMOLED (Active Matrix OLED): commonly found in brands such as Samsung and Apple, with more vibrant colors.

LTPO AMOLED: Supports variable refresh rates (such as 1Hz-120Hz) to improve smoothness while reducing power consumption, commonly seen in flagship models.

Micro LED: At the forefront of technology, it has the advantages of OLED and solves the problem of screen burn-in, but currently it is expensive and has not been widely commercialized.

Suitable for:

✅ Users who pursue high contrast and bright colors (like the "transparency" of the screen)

✅ Users who enjoy gaming and high refresh rate experience (OLED screen response speed is fast)

✅ Users who hope their phones are thinner and lighter (with a more streamlined OLED structure)

Representative models: iPhone 15 Pro, Samsung Galaxy S23 Ultra, Xiaomi 14 Pro



3、 Refresh rate: an important factor affecting smoothness

In addition to screen type, refresh rate is also a key indicator that affects the screen experience of mobile phones.

60Hz (standard refresh rate): The most basic refresh rate, with stable but not smooth images.

90Hz/120Hz (high refresh rate): smoother operation, suitable for sliding social media, playing games and other scenarios.

144Hz and above: commonly found in gaming phones, the ultra-high refresh rate brings a more ultimate smooth experience.

LTPO variable refresh rate (1Hz-120Hz): The refresh rate can be dynamically adjusted according to the usage scenario, which is energy-saving and smooth. It is standard on flagship models.

Suitable for people with high screen refresh rate:

✅ I enjoy playing games (faster response time, reduced ghosting)

✅ Regularly browse social media (smoother scrolling, better visual experience)

✅ Pursuing power saving and smoothness (LTPO technology is the best choice)

4、 Eye protection mode: reduces screen damage to the eyes

Staring at the screen for a long time can easily cause eye fatigue, blue light damage, and other problems. The following techniques can alleviate them to a certain extent:

DC dimming (reducing low-frequency flicker): More eye friendly than PWM dimming, but may affect color accuracy.

Low blue light mode: reduces high-energy blue light radiation and lowers the risk of eye damage.

• Paper like eye protection mode (such as Honor like natural light screen): simulates the reading effect of paper and is suitable for long-term reading.

If your eyes are sensitive, it is recommended to choose a phone that supports DC dimming or eye protection mode.
