My wife's iPhone SE is a couple years old and many drops in (probably average of 1/week at least). It's been rock solid this whole time, but earlier today, it started having horizontal lines going up and down the display, and the lines seem to get more intense if the iPhone is doing some heavy processing or rendering something on the screen.

I tried resetting the phone, updating to iOS 11, and shutting it off, waiting a while, then turning it back on, but nothing seems to get the lines to go away completely. My wife said it was intermittent at first, but it seems to be happening all the time now that I'm trying to debug it.
Any ideas? Do I need to replace the front panel assembly (e.g. using replacement from iFixIt)? Or could this be something deeper that would require more work/replacement than it's worth?
