lines all over the screen and display flickering

[Spurthy]

Hello, 

           My laptop's display was totally fine until last month. I didn't use it for 2 weeks, but it was fully charged and shut down. Then I turned it on a week ago and I noticed some horizontal and vertical lines all over the screen. I had restarted the laptop and it was fine then I had shut it down after using it for a few hours. Then again, after a week i.e., last night, I've turned it on, and the issue has started a few minutes after I started using it. Whenever I restart the laptop, the screen turns normal but after a few minutes, this issue starts showing up and doesn't go away until I turn it off. however, those lines are appreciated only on a dark background. I also notice slight flickering of the display sometimes. What is the solution for this?
