Causes of Mura:
1. LCD screen: Mura is caused by a mismatch between the motherboard drive voltage and the LCD drive voltage design, or the liquid crystal in the LCD is subject to ion accumulation, resulting in electric field charge polarization. This polarization is usually caused by the use of lower-quality liquid crystal materials.
2. OLED screen: Mura is related to the lifespan and luminous efficiency of RGB luminescent materials, especially blue luminescent materials, which have always been a challenge in OLED research and development. OLED screens are highly sensitive to water vapor and oxygen, which may cause screen degradation or failure once exposed.
OLED standards:
A universal standard for OLED screens is T95, which represents the time it takes for brightness to decay to 95% at maximum manual brightness. For example, Apple requires that its OLED screens be free from mura or aging problems within 500 hours.
To prevent mura issue, we recommend taking the following steps:
1. Avoid displaying static images for long periods: Please avoid displaying the same image on the screen for a long time, particularly high-contrast images.
2. Use dynamic screensavers: Regularly using dynamic screensavers can help reduce mura issues.
3. Adjust the screen brightness: Do not use maximum brightness for extended periods. Appropriately reducing screen brightness can extend screen life.
4. Ambient temperature: Avoid using the screen in extremely hot or cold environments, as temperature fluctuations may exacerbate mura problems.
We are confident that these suggestions can help optimize the use of your screen and reduce the occurrence of mura problems. If you have any further questions or need additional help, please do not hesitate to contact us. We are here to assist you.
