My battery is bloated. Is this the reason why my screen turned black?

video link

The link shows exactly what happened to my device. I'm planning to buy an iFixit kit for battery replacement. However, I'm still reluctant because what if the black screen is another issue altogether? My first inference is that since the battery is bloated, it may have disconnected some modules inside, like the one for the display. I just wanna be sure before buying.

I hope someone can help me in this. I've searched sites discussing about bloated batteries but I haven't found any case like mine. Thank you!
