Why did the screen stop working when it fell from less than a foot?

First of all, I don't know the exact model of my Amazon Kindle so the device may not be entirely accurate (yes this is kind of a throw away email because I don't have a main google account and I did sign up specifically for this question but I really want/need help). When I was going to pick my device up (no screen protector of any kind), it slipped from my hands and it got dropped less than a foot. I have dropped it before farther with no issues other than some cracks on the screen and no new crack appeared, but once I turned it on the screen only displayed black with some flickering and multicolored lines. I tried hitting the back of it and dropping it from short distances and holding the power button and while I have made some progress fixing it I'm having no further luck. Now around a third of the screen (bottom right corner) displays normally other than some shacking but the rest is still completely broken (the right section of the screen can be different colors but it's usually mostly a solid color). Both the volume and power buttons still work because even though I can't see the pop ups from them, they still make the same sound as normal. I took a picture of what it looks like while on and I have also taken one of how it looks while off to show the previous cracks on the screen. I'm wondering if there's any way to fix it at all. Thanks.
