Lines on screen after dropping

A

AC Question

Hello everybody! Today i dropped my ZTE BLADE Q MINI and the screen didn't crack, only i can see is many thin horizontal lines that make display look old and ugly. Also there are sometimes vertical lines and they are white when i open google chrome or some app where the display is almost white - that lines depend on dominant display color. After a minute or less they are gone, but that's very annoying. What is the problem? Can it be moved LCD connector or something? Thanks in advance! Sorry for bad english!!!! :D :D :D :D :D :D :D :D
