Evotab Tablet Pixels Problem

[Alexandru Constantin]

Good evening,
I opened my tablet today and that's what I saw. Is there something that I could do to make it come back to normal ?

Did you drop it or something? Because it looks like the screen is broken.

I dropped it one time but with the backside, it doesn't fell on the display. Sorry for my bad english.
