There are grid stripes or horizontal stripes on the screen in the hinge area of my HUAWEI Mate XT

Problem:

1. When the outward folding hinge is folded for a long time and then unfolded with the screen turned off, grid stripes appear.
2. When the two sides of the inward folding hinge are folded for a long time and then unfolded with the screen turned off, grid stripes appear.

Thank you for your support and feedback. To improve the quality and durability, the outward and inward folding hinge areas are reinforced. Slight horizontal stripes may appear when the screen is turned off, which does not affect the normal functions of the screen.
