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.

Comparison of Three Packaging Technologies


1. COG (Chip On Glass): This is one of the most traditional packaging methods, with low technical barriers and low costs, and is the most commonly used technology for screens. From the English version, it can also be seen that this packaging method involves placing IC chips and FPC cables on the back glass of the screen. However, due to the IC chip being located directly below the LCD, a considerable amount of screen space is squeezed, inevitably resulting in a "chin".




2. COF (Chip On Film): Essentially, it is an upgraded version of COG and a key factor in the current screen transformation. The main principle is to place the display driver IC chip into a flexible FPC cable, and then fold it under the screen using the characteristics of the FPC itself. Specifically, through hot pressing, the Gold Bump of the IC chip and the Inner Lead on the flexible substrate circuit will be bonded together. Due to the release of space occupied by IC chips, the lower frame width can generally be reduced by at least 1.5 millimeters.






3. COP (Chip On Pi): It belongs to the process with the most reduced borders, but it should be emphasized that the premise of this process is the application of flexible OLED screens, which utilize the bending characteristics of flexible OLEDs to bend all cables and ICs below the screen. Of course, OLED is also divided into two types: hard screens and flexible screens. To use this technology, a combination of COP packaging technology and flexible OLED must be used. However, this technology still has the disadvantages of high cost and low yield rate.





After introducing the technical foundations of COG, COF, and COP, let's take a look at the practical application of COP technology on Samsung S8. This phone adopts innovative COP screen packaging technology, which allows the screen edges to bend without physical limitations, achieving a nearly borderless visual effect. This technology not only enhances the aesthetic appearance of mobile phones, but also brings them a wider display space.

011. Analysis of Mobile Screen Technology
1.1 Overview of LCD and OLED
LCD relies on external light sources, while OLED can emit light on its own; The two principles are fundamentally different.
1.2 LCD Screen Technology
LCD screen, also known as Liquid Crystal Display, has become a mature technology after a long period of development and is widely used in various types of mobile phone screens. At present, screen technologies such as TFT, IPS, and SLCD can all be classified as LCD screens. Among them, TFT, as a general term for LCD panels, was once the mainstream of early LCD screens. Although its display effect was mediocre, its cost was low, so it was still adopted by many low-end models.IPS screens, often referred to as "SuperTFT" in the industry, are an upgraded form of LCD screens that essentially still belong to the category of TFT screens. Compared to ordinary TFT screens, IPS screens have a more transparent display effect, bright colors, and a wider viewing angle, reportedly even reaching a viewing angle range of nearly 180 °. SLCD, also known as "Super LCD", belongs to a higher level of LCD screen technology, and its excellent display effect and good color reproduction ability have won widespread praise.
1.3 OLED Display Technology
Compared with LCD screens, the biggest feature of OLED screens is the self luminous display technology of pixels, which makes OLED screens more outstanding in display effects and become the mainstream direction of future screen technology development. At present, AMOLED screens dominate the OLED field, and Samsung, as a leader in mastering core technologies, has achieved increasingly accurate color reproduction in its products, with significant improvements in color cast compared to earlier products. Super AMOLED， As an important product of Samsung in the OLED display market, it is widely praised for its high color saturation and vivid display effects, especially in terms of color performance. Samsung's Super AMOLED screen is considered a leader in the industry.
1.4 [Introduction to 120Hz Flow Rate Screen]
Recently, mobile phone manufacturers have launched 120Hz streaming screens, which brings us a brand new visual experience through technological innovation. The flow rate screen, with its high refresh rate of 120Hz, significantly surpasses the refresh rate of traditional 60Hz mobile phone screens. In fact, the refresh rate of 120Hz flow rate screens has been improved, and optimized circuit components have been used to achieve higher screen refresh rates.

In fact, the perception ability of the human eye is often misled. For example, the common 24FPS frame rate in movies, which plays 24 frames per second, sacrifices 1/24 of a second of motion detail despite the use of motion blur technology to make the images appear coherent. This trade-off may be acceptable for movies, but in games, each frame is a static image rendered in real-time. If it is still presented at 24 frames per second, it will result in disjointed actions. The high refresh rate of the flow screen helps to improve the performance of dynamic images, bringing users a smoother visual experience.

Overall, mobile screen technology is developing towards higher refresh rates and better display effects. LCD occupies a place in the market with its mature technology and diversity, while OLED is gradually becoming mainstream with its excellent display effects and self luminous advantages. With the continuous innovation of technology, future mobile phone screens will definitely bring us more surprises and better user experience
