A hairline crack is a crack as thin as a piece of hair

That means that the crack is as thin as a piece of hair

Just like a hairline crack on any sheet of glass. A thin crack on its surface.

A hairline crack is where something is cracked or broken but the material at the two sides of the crack is still tightly pressed together. It has no opening or notch, just a visible line where the break is.

It's the opposite of a crack where there's a split or gap opening up in something.

If it's in the context of an LCD screen or a touchscreen, a crack in the surface usually means internal damage to the grids of transparent conductive layers applied to the material - broken connections - so the display / touchscreen is likely compromised as well.

This is what you are looking at, shown as separate layers:

  • Is there a way for me to just patch a small crack in my iPhone 5 screen? I dropped my iphone 5 the other day and now there's a small crack along the left edge of the glass that does not even go onto the LCD portion of the screen. I do not want to pay $299 for a small crack like this so i was wondering if there's any way to just patch it up so it is less visible.
