How To Identify The Quality Of Mobile Phone Screens? Essential Tips For Mobile Phone Repair Shop Practitioners

Dear mobile phone repair shop practitioners, the screen is one of the core components of the mobile phone, and its quality directly affects the customer's experience and satisfaction. Today, let's discuss how to identify the quality of mobile phone screens to help you provide customers with better services during the repair process.
1. Appearance inspection
The fit of the screen to the body
The original screen usually fits perfectly with the mobile phone body without any gaps or misalignment. Check whether the edge of the screen is flat and whether there is any glue residue, and observe whether the screen glass is smooth and scratch-free. In addition, the color and texture of the screen and the body should also be consistent.
Logo and printing
Original screens usually have clear brand logos and high-quality printing. For example, Apple's "" logo or Samsung's "Samsung" logo should be clearly visible, and the printed fonts should not be blurred or wrong.
2. Display effect
Brightness and contrast
Screen brightness is an important indicator of quality. In strong light, a screen with high brightness can still display content clearly. At the same time, a screen with high contrast has better details when displaying black and white or dark backgrounds.
Color accuracy
Observe whether the colors displayed on the screen are accurately restored. For example, white should be pure white, black should be pure black, and there should be no color cast. In addition, when viewing the screen from different angles, there should be no obvious changes in color and brightness.
Resolution and clarity
High-resolution screens (such as 2K) have more delicate display effects. You can observe whether the edges of text or icons are clear by enlarging them.
Three, touch sensitivity
Response speed and accuracy
The touch response of the original screen is usually very sensitive and accurate. When performing multi-touch operations, the screen should respond quickly and without delay.
Feedback effect
The vibration feedback during touch should be uniform and natural, and the sound feedback should also be clear.
Four, professional detection
Hardware information
Use professional tools (such as CPU-Z or AIDA64) to check the screen model and manufacturing date, and compare them with official data. You can also get more information through the factory mode of the mobile phone.
Serial number and IMEI code
Check whether the serial number and IMEI code of the screen are consistent with the official data.
5. Beware of repair tricks
There are some unscrupulous merchants in the repair industry who use inferior assembled screens or refurbished screens as original screens. Therefore, it is recommended to choose original screens as much as possible during repairs, and carefully identify them using the above methods.
Dear practitioners, it is not difficult to identify the quality of mobile phone screens. The key lies in careful observation and professional testing. I hope that the above methods can help you provide customers with more reliable screen replacement services during the repair process and win more customers' trust and support!
