QLED has nothing to do with OLED. QLED is just a marketing term for Samsung’s LED TV’s. OLED is vastly different than any LED TV and the only two manufacturers selling OLED TV’s are LG and Sony. OLED has better contrast, but has a more reflective screen and doesn’t get as bright. So if you have a bright room, LED based TV’s will provide a better picture. Look at the 900, or Z9 series Sony TV’s if you need close to the same contrast as the OLED, but with 3-4x the brightness.
