LCD screen light leakage refers to the phenomenon of obvious bright spots or halos appearing at the edges or corners of the screen in full black or dark colors. Below we will explain the reasons and solutions for light leakage in LCD screens, summarized as follows:
1.The main reason for light leakage in LCD screens
Category | Specific reason | Instructions |
Manufacturing factors | The screen is not tightly sealed | Damaged during production or transportation, resulting in inadequate sealing of the screen edges. |
Assembly process defects | Uneven border compression and excessive gap between the screen and the border. | |
Backlight module issue | The installation position of LED light strips or light guide plates is offset and the quality is poor. | |
Physical factors | External compression | The screen is subjected to compression or collision, causing deformation of the internal structure. |
Usage environment | Temperature change | Long term exposure to extreme temperatures can cause material deformation or aging. |
2. Solution to light leakage
Applicable scenarios | Specific measures | Instructions |
light bias | ADJUST SETTINGS | Reduce screen brightness, contrast, and minimize visual impact. |
Changing the environment | Avoid using in completely dark environments to reduce light leakage perception. | |
Clearly leaking light | Contact after-sales service | Contact the brand after-sales service during the warranty period, provide photo or video evidence, and apply for repair or replacement. |
Serious light leakage | Professional maintenance | Disassemble the screen by professionals, reseal or replace the backlight module. |
Replace the screen | If the maintenance cost is too high or the screen is severely aged, it is recommended to replace the screen with a new one. |
1.Suggestions for preventing light leakage
When making a purchase: choose brands and models with good reputation and strict quality control.
In use: Avoid external compression or collision, and maintain a suitable temperature for use.
Daily maintenance: Regularly clean the screen to avoid dust and impurities affecting the screen's sealing.
2.Special Reminder
Normal phenomenon: Slight light leakage of LCD screens in dark environments is normal and meets industry standards.
Misjudgment risk: In bright environments or when using bright images, the phenomenon of light leakage may not be obvious, and accurate judgment is necessary.
In summary, although LCD screen light leakage is common, it can be effectively reduced or avoided through reasonable selection, correct use, and timely maintenance. In case of serious light leakage, it is recommended to contact the brand's after-sales or professional maintenance personnel in a timely manner to ensure the best user experience.
