Light patch on ThinkPad T400 WXGA+ LED BL display

I've had my ThinkPad for about four months and have noticed a small patch on the LCD WXGA+ /w LED BL display that appears brighter than the rest of the display.  The problem is most noticeable on light backgrounds with the brightness turned up high. The patch is about the  size of a dime.

 

I was wondering what the problem might be, whether it would be covered by warranty and how long it would take for this to be fixed via warranty?

 

Thanks, for your help.

Re: Light patch on ThinkPad T400 WXGA+ LED BL display

this light spot is due to a pressure spot, or there is a distortion in the LCD polarising film due to some heavy pressure. You would need to get the LCD changed, i think it is covered under warranty.
