my friend took her ipad out of her book bag to check the time and a quarter of the the screen was white with a tiny black mark she never droped it and its not cracked. i reset it for her but black lines went everywher and keep on scanning the screen

My friend took out her ipad to check the time and a quarter of her screen was white so I told her to hold the home button and the lock button to reset it it didn't work. black lines started scanning it, it looks like a glitch! we did that like six times! Then we tried we took the case off to see if it was loose but it wasn't , so we let it do its thing and it started scanning black lines going up apps turning upside down my friend can still access her ipad but the white thing is in the way! we are calling apple support after school I hope she can fix it!!!!!
