I've been having a phone display problem which makes the display unreadable as seen in the images, but still usable (the top of the screen works, so it probably is a hardware problem).

I did some research and there's a component that has a weird dark spot and indent, which could be the reason for this.

My question is: what is the name of the component shown circled (the copper-colour object)? Thanks for any help.

Note: Phone is asus zenfone 2 ZE551ML, had for ~3 yrs, defect started without dropping. I don't know what site to post it on, this seemed the most appropriate.
