The main difference between an LED TV and an OLED TV is that the pixels of an OLED TV are self illuminating, whereas the LEDs in an LED TV are used to light an LCD display. ... OLED TVs feature a wider viewing angle than do LED TVs. With OLED, the colors do not get washed out when viewers watch from extreme angles.
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.

It offers the best performance for its value compared to other OLEDs, even if they have similar picture quality.

QLED is brighter.
In my tests, however, OLED TVs can still get plenty bright for most rooms, and their superior contrast still allows them to deliver a better overall HDR image than any QLED/LCD TV I've tested.
LG vs. Samsung: the contenders
But both LG and Samsung have developed their smart TVs from scratch. ... LG manufactures OLED displays, which are considered to be the best in terms of color and contrast. Samsung still uses QLED technology, which can't quite match OLED for picture quality.
