Put another way, QLED is an enhanced LED TV, while OLED TVs feature an entirely different type of backlighting technology. So, what happens if you add that same layer of quantum dots from a QLED to a self-emissive OLED display? QD-OLED TVs generally can’t get as bright as the most powerful QLED TVs, but they’re still plenty bright. Other brands have found their own way to make OLED TVs brighter, overcoming the most common complaint about the tech. Brightness alone is not the end-all-be-all of TV performance, especially for OLED TVs.
