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.
