China's Haier demonstrated OLED TVs at IFA 2015. We do not have any information on those TVs, beside this video which only shows them for a few seconds at the beginning:
Back in January Haier unveiled their 55" curved super-slim (1.5 mm) Full-HD 55H9800 OLED TV. it may be that this is the same TV shown now. As far as I know the H9800 is not shipping yet.
