Update: TCL says it issued that statement by mistake, and it has no current plans to ship a QD-OLED TV in 2023
TCL announced that it is set to launch its first QD-OLED TV in the coming months. If all goes according to plan, TCL will be the third company (following Samsung and Sony) to offer QD-OLED TVs.
That's the only information we have so far. The TV will likely be offered in 55-inch, 65-inch and/or 77-inch sizes (the available QD-OLED panels today) with a 4K resolution and a refresh rate of 144Hz. That's the current QD-OLED standard.
