The Samsung QN90B proves you don't need OLED technology to give a top-notch picture. This TV's QLED panel is augmented by mini-LED for a brighter image than any OLED TV. The spectacular contrast OLED is a different technology that uses self-emissive pixels. Each pixel turns itself on and off and emits light in all directions. This means that OLEDs have very wide viewing angles, even better than IPS panels, and they also have a near-infinite contrast ratio.

With the arrival of QLED TVs, many people are interested in what makes them different from OLEDs. It all boils down to different technological principles. QLED TVs use Quantum dots which are inorganic, durable, stable and allow for excellent color and brightness. Meanwhile OLED TVs use a controversial organic material that leaves them

Brightness- QLED TVs can get much brighter than OLED TVs, especially in HDR10 content due to the brightness range. However, OLED screens are generally better at producing deep blacks and thus have better contrast ratios. Contrast Ratio- OLED TVs offer better contrast ratios than any LCD TV, including QLED TVs. However, QLED technology is structured to withstand the test of time better than its OLED, LED, and LCD counterparts. The gradual dimming of the backlight, the most likely form of wear a QLED TV will sustain, occurs at such a slow rate that it often goes unnoticed, preserving the immersive experience of the home theater. Mini-LED TVs are, in every other respect, the same as standard QLED TVs, so the same benefits apply to both: Screen sizes can be bigger, and prices can be lower than OLED TVs (for now, anyway). As
Which is better: ULED vs QLED vs OLED. Since LED TVs are powered by a backlit, their brightness will double that of OLED TVs. However, a QLED television should be a good choice because a quantum dot filter can improve colour intensity as compared to standard LED television. Hopefully, you have found out which one to choose ULED vs QLED.
