Macbook Air screen with white horizontal lines

Hi.

I am using my computer: MacBook Air (M1, 2020) with Version 11.5.2.

Yesterday, around 12:00, when I open my computer after arriving home, bad things happened.

There are numerous white lines (throughout the whole screen, equally distributed, horizontally) on my screen.

I didn't fall my computer nor spilling water on it.

I tried to restart in safe mode, reset NVRAM, SMC and using Apple Diagnosis.

IT IS WHITE but not green nor black nor green nor purple.

My friends think that it may be about my screen resolution problem, but I didn't know where to fix it.

I started to use this computer around mid-August 2021 (FIRST HANDED).
