Klaynos Posted March 5, 2013 Share Posted March 5, 2013 I suspect it is a thin film effect very similar to oil floating on water. 1 Link to comment Share on other sites More sharing options...
Externet Posted March 5, 2013 Share Posted March 5, 2013 Probably not a led television but a LCD television with led backlighting. All LCD displays have a polarizer film adhered to the glass screen. That is what is causing the reflection you perceive. The leds have nothing to do with it. Link to comment Share on other sites More sharing options...
