In part, that's because LED TVs are available in both 1080p HD (1920 x 1080 pixels) and 4K Ultra HD (3840 x 2160 pixels), while OLED is 4K only. OLED TVs also deliver picture quality that's far superior to typical LED models. Only the very best LED TVs produce a picture that comes close to OLED.

QLED panels are not self-emissive, instead lit by LEDs along the edge (just like an Edge LED-backlit LCD). The advantages of QLED TVs are that they use a quantum dot color filter and are capable of significantly higher brightness than OLED TVs. ... But only if they're cheaper than OLED, which for now remains the benchmark.
