A:Answer In the US, the 55", 65", and 77" are QD OLED while the 42", 48", and 83" are WOLED. Globally, most model sizes use a WOLED screen, but often at least one size uses a QD-OLED screen, which can be identified by the last four digits of the long model code in your region; if the fourth to last digit of the model code is an 'E,' the TV probably uses a WOLED panel. For example, in the UK the 65-inch model ends with TXXU, so you should end up with a QD-OLED panel if you buy that size. See rtings dot com for detailed information.
