Tablet has a black spot after fall damage

[Shadow_Step]

Long story short, my tablet fell. It has dropped four times already but in the first three only screen cracks happened. In the fourth drop, the tablet's screen did crack but so did a black spot on top of the screen. I am not sure what it is but I can only guess something cracked in the inside as well or something went loose when it fell. The tablet is an Acer A1-830 and all I want to know is what it is and how I can fix it myself or where to take it to get fixed and if there is a place, how much will it cost?

It's toast. Any 'repair' would cost more than a new one.
