Chipped Logic Board, Part of Screen Not Working

Hello, I replaced my iPhone 4s screen, but in the process, on the top, middle of the logic board, where the screw goes, that part has chipped off. Now, when using my iPhone, the very right part of the screen does not respond to touch. (When typing, the P,L, and backspace do not work.)

The screen is also jumpy. I know it is not the screen because I tried 3 different OEM screens, all do the same thing.

Could the chipped logic board be the problem?
