Screen gets blurry while pressed?!

Hey guys. Today I noticed with a shock that my screen gets blurry when I press it in a certain way. The best way to describe it is to use the example of tft computer screen. I mean when you use your finger and press kinda hard on the screen surface than somehow rings are expanding from the pressing point, like when there is a drop of water on a still water surface. It is weird because it is more in the lower part of my screen. Now my question: does anybody have similar issues or is my screen broken?



Thanks a lot for your help guys!
