After the LCD screen ages, color distortion often occurs. This is because the aging of the backlight and liquid crystal layer of the LCD screen causes color shift and distortion. The aging LCD screen will appear yellowish, bluish or reddish in color, greatly reducing the image display effect. Aging LCD screens are also prone to color unevenness, causing colors in certain areas to be significantly darker or lighter.
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 LCD screen is severely aged, the brightness decrease 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.
As the LCD screen ages, its response speed will slow down. The reaction speed of the LCD screen refers to the time required for the liquid crystal molecules to transition from one state to another under the action of an electric field. The aging LCD screen has a slower reaction speed due to the reduced mobility of the liquid crystal molecules. This will cause image retention and blurring on the screen when displaying rapidly changing images, affecting the user's viewing experience.
After the LCD screen ages, its heat will gradually increase. This is because the energy conversion efficiency of the backlight 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, causing the surface temperature of the display to rise. This will not only affect the user experience, but may also cause damage to other components inside the display.
After the LCD screen ages, problems with bright spots and dark spots often occur. A bright spot refers to a situation where the brightness of a certain pixel on the LCD screen is abnormally higher than that of surrounding pixels, while the opposite is true for dark spots. This is caused by uneven aging of the LCD backlight and liquid crystal molecules. The existence of bright spots and dark spots will affect the display effect of the screen and reduce the quality of the image.
As the LCD screen ages, the number of dead pixels will gradually increase. Bad pixels refer to the situation where a certain pixel on the LCD screen cannot work properly, which usually manifests itself as black or abnormal color display at the pixel. After the LCD screen ages, the aging of the backlight and liquid crystal molecules will increase the probability of pixel failure, resulting in more dead pixels. The existence of dead pixels will affect the quality of the image and reduce the user's viewing experience.
As the LCD screen ages, its viewing angle will become narrower. Viewing angle refers to the range within which the image can be kept clearly visible when users view 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 it deviates from the direct angle, the brightness and contrast of the image will decrease significantly, causing the image to be blurry.
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.
