According to reports both Samsung and LG Display plan to introduce 55" OLED TVs at CES 2012 (January 10). This is not surprising as this was announced before. According to the new reports, both companies want to introduce the products before the 2012 Olympics (which is a big event towards which many consumers buy a new TV) - which means we can expect those OLED TVs shipping at around July 2011.

The same reports re-iterates the old rumors regarding an Apple OLED TV. I'm still skeptical on this because in 2012 OLED TV capacity will be low (LG for example says it will be able to produce around 30,000 panels per month) - not enough for Apple. Samsung will also be producing their large panels in a pilot line and will not be able to mass produce these panels.
