1. Color distortion

After the LCD screen is aging, the phenomenon of color distortion often occurs. This is because the backlight of the LCD screen and the aging of the liquid crystal layer cause color shift and distortion. The aging LCD screen will appear yellowish, bluish or reddish in color, which greatly reduces the display effect of the image. Aging LCD screens are also prone to color unevenness, causing certain areas to be noticeably darker or lighter.

2. Brightness drops

After the LCD screen ages, its brightness will gradually decrease. This is because the aging of the backlight causes the brightness to decrease. When the aging of the LCD screen is severe, the phenomenon of brightness drop is particularly obvious, making the screen display dim. When users use aging LCD screens, they often need to increase the screen brightness to achieve normal viewing effects. This not only causes certain damage to the eyes, but also increases power consumption.

3. Slower response

As the LCD screen ages, its response speed will slow down. The response speed of the LCD screen refers to the time required for the liquid crystal molecules to change from one state to another under the action of an electric field. Due to the decline in the mobility of liquid crystal molecules in aging LCD screens, the response speed becomes slower. This will cause afterimages and blurring when the screen displays fast-changing images, affecting the user's viewing experience.

4. Increased display heat

As the LCD screen ages, its heat generation will gradually increase. This is because the energy conversion efficiency of the backlight source decreases after aging, resulting in an increase in the proportion of energy converted into heat. When an aging LCD screen is used for a long time, it will generate a lot of heat, which will increase the surface temperature of the display. This will not only affect the user experience, but may also cause damage to other components inside the display.

5. Bright and dark spots

After the LCD screen is aging, the problem of bright and dark spots often appears. A bright spot refers to the situation where the brightness of a certain pixel on the LCD screen is abnormally higher than that of the surrounding pixels, while the dark spot is the opposite. This is due to the uneven aging of the LCD backlight and liquid crystal molecules. The existence of bright and dark spots will affect the display effect of the screen and reduce the quality of the image.

6. More dead pixels

As the LCD screen ages, the number of dead pixels will gradually increase. A bad pixel refers to the situation where a certain pixel on the LCD screen cannot work normally, and it usually shows that the pixel is displayed as black or the color is abnormal. After the aging of the LCD screen, the aging of the backlight source and liquid crystal molecules will lead to an increase in the probability of pixel failure, resulting in more dead pixels. The existence of dead pixels will affect the image quality and reduce the user's viewing experience.

7. Narrow viewing angle

As the LCD screen ages, its viewing angle will become narrower. The viewing angle refers to the range within which the user can keep the image clearly visible when viewing the LCD screen from different angles. Due to the aging of the backlight and liquid crystal molecules, the viewing angle range of an aging LCD screen will become narrower. Users need to face the screen directly to obtain the best viewing effect. Once the angle is deviated from the front, the brightness and contrast of the image will be significantly reduced, resulting in blurred images.

8. Increased display reflections

As the LCD screen ages, the reflection on its surface increases. The reflection of the LCD screen refers to the phenomenon that the light passes through the liquid crystal layer from the backlight and is reflected by the liquid crystal layer again. The reflectivity of an aging LCD screen will increase due to the aging of the backlight and liquid crystal molecules, resulting in increased reflection on the display surface. This will reduce the visibility of the display under strong light, and the reflected light will interfere with the user's viewing of the image. To avoid reflection issues, users need to take some measures, such as adjusting the angle of the monitor or using an anti-glare screen protector

The aging of the LCD screen will cause color distortion, decreased brightness, slower response speed, increased display heat, increased bright and dark spots, increased dead pixels, narrowed viewing angles, and increased display reflection. These problems will affect the user's viewing experience and may have a certain impact on the normal use of the monitor. When selecting and using an LCD screen, users need to pay attention to its degree of aging and promptly replace seriously aged LCD screens.
