Screen Discoloration

[Cjedl]

Today I noticed a orange stripe with a purple hue on the bottom right corner of my Dell laptop. What is it and what can I do to fix it?

Seems this is a warranty claim... http://en.community.dell.com/support-forums/peripherals/f/3529/t/20001147

If out of warranty, might be cable to display - clean (or replace) and reconnect - but probably use it until it is awful.
