What is the cause of the film arch in the backlight of display screen?

The reasons why the backlight film of the display screen is arched may be as follows:

1. temperature change: the backlight film of the display screen usually consists of uniform backlight. When the display screen runs for a long time or the temperature changes greatly, the backlight film may arch due to thermal expansion and cold contraction.

2. Improper operation: frequently switching the display screen or hanging the display screen for a long time may cause uneven stress on the backlight film, thus causing arching deformation.

3. Quality problem: The quality problem of the backlight film may also be one of the reasons for arching, and defects in the manufacturing or design process may lead to the relaxation or deformation of the backlight film.

The arched backlight film of the display screen will not only affect the display effect, but also shorten the life of the display screen. For the arched display screen in use, it is recommended to contact professional technicians for maintenance or replacement of backlight film.
