  Causes of dead pixels on LCD screens

  1. Defects in the manufacturing process: There will inevitably be some unavoidable defects in the manufacturing process of LCD screens, which may cause dead pixels on the screen.

  2. Damage caused by external force: During use, the LCD screen is subject to external collisions, squeezes and other forces, which can easily lead to the appearance of dead pixels.

  Measures to prevent dead pixels on LCD screens

  1. Buy a genuine LCD screen: Buying an LCD screen produced by a regular manufacturer is the first step to avoid dead pixels. Genuine LCD screens pay more attention to quality control during the manufacturing process, which can effectively reduce the occurrence rate of dead pixels.

  2. Protect the LCD screen: When using the LCD screen, pay attention to avoid damage to the screen from external forces such as collision and extrusion. You can use a special screen protector or protective case to protect the screen from direct contact with external objects.

  3. Avoid frequently switching the screen on and off: Frequently switching the LCD screen on and off can easily cause the internal components of the screen to loosen, thereby increasing the chance of dead pixels. Therefore, when you do not need to use the screen, it is best to keep the screen on or extend the screen sleep time.

  4. Avoid displaying static images for a long time: Displaying static images for a long time will cause the pixels on the LCD screen to be in the same brightness state for a long time, which is prone to dead pixels. You can use a screen saver appropriately or set a screen sleep time to reduce the occurrence of dead pixels.

  5. Pay attention to screen cleaning: Regular cleaning of the LCD screen can effectively prevent dust, stains, etc. from damaging the screen and keep the screen clean.

  How to deal with dead pixels on LCD screens

  1. Dead pixel test: After purchasing an LCD screen or using it for a period of time, you can use the dead pixel test software to detect whether there are dead pixels on the screen. If you find any dead pixels on the screen, you can contact after-sales service in time.

  2. After-sales maintenance: If the LCD screen has broken pixels, you can contact after-sales service for repair or replacement. The after-sales service of regular manufacturers will perform corresponding repairs or replacements according to the situation of bad pixels.

  In summary, to prevent LCD screen dead pixels, you need to start with purchasing genuine screens, protecting the screens, and avoiding excessive use.
