that is kind of cool to be honest, never seen anything like it.... just also curious as to how a smudge got on the inside of the screen?! I don't think you killed the display, the pixels haven't died (they are two different colours), although i'm not really sure what happened, if you applied too much pressure the display would have cracked in a spiderweb. Exhaust all software options and then take the thing to bits and put back together before buying a new LCD Replacement!
