Question about Samsung QE55S90FAE

This 55-inch model is a WRGB OLED display (also known as WOLED). The exact model designation is QE55S92FAE, whereby the "FAE" at the end indicates the WRGB OLED equipment. In contrast, the designation "FAT" would indicate a QD OLED panel. In the S90F series, only the 65-inch model has a QD OLED panel, while all other sizes, including the 55-inch model, are equipped with WRGB OLED panels.
