Earlier today, The Korea Times reported that Samsung would stop selling LCD panels to Apple. That report seems to be wrong. Samsung has come out to say that, "Samsung Display has never tried to cut the supply for LCD panels to Apple."
Basically: if the LCD panel relationship has ended between Apple and Samsung (two companies who aren't exactly chummy with each other), the blood isn't on Samsung's hands. The statement CNET got from Samsung is pretty clear that they "never tried to cut the supply" to Apple.
Apple hasn't replied to that statement yet so we don't know if the two companies are still in business with each other, all we know is that Samsung was once the single largest supplier of LCD panels to Apple and now they're supposedly not a part of the iPad Mini. [CNET]
