China's Hisense is showing a 55" flat OLED TV prototype at CES 2014. Apparently the staff at Hisense's booth made it clear that this is just a prototype and the company has no plans to release it as a product any time soon.

I'm not sure who makes the OLED panel itself, but it's highly likely it is made by LG Display (LGD is already providing OLED panels for China's Skyworth). Hisense thus joins two other Chinese makers (TCL and Haier) that are also showing OLED prototypes at CES. Hopefully Hisens obtained those panels with permission...

Interestingly, this is not the first OLED TV Hisense unveiled. Back in 2011 they showed a 15" OLED TV prototype, with plans to launch it later that year (which never happened though). The 15" OLED was provided by LG Display.
