Why is there a 3 cm purple stripe on my retina macbook screen?

I have a weird purple stripe on my screen when I have a black background with high brightness.

It looks like this:

I am guessing it is like 3cm long and like 0,3 cm thick.

I have done al the software resets (SMC, PRAM stuff like that) and the problem persists. When I start my mac, you can already see the purple stripe due to the black background, even before OS X is loaded. On white you don't see it at all. I think it is the graphics card or screen that is malfunctioning.

Has anybody:

- experienced this?

- found what causes this?

- know if this falls into the replacement programme of the graphic cards that was recently announced here:

Thank you in advance for looking/answering! 🙂
