QNED and OLED are two different TV display technologies. Here are the main differences between the two based on the search results:

QNED:

• QNED TVs are LCD-based and use a combination of quantum dot and NanoCell technologies with Mini LED backlighting.
• QNED TVs have up to 30,000 tiny LEDs paired with nearly 2,500 dimming zones, resulting in great peak brightness levels and an improved contrast ratio compared to regular LCD TVs.
• QNED pixels can only be dimmed, not switched off, so the TV cant display real black. As a result, QNED screens display a less strong contrast than OLED screens.
• QNED televisions have a less wide viewing angle than OLED televisions.

OLED:

• OLED TVs use organic, carbon-based material that can produce a wider array of colors or no color at all.
• OLED TVs are touted to have the best blacks because individual pixels can be switched off, resulting in a stronger contrast than QNED screens.
• OLED TVs have a better viewing angle than QNED televisions.

In summary, QNED TVs use Mini LED backlighting and quantum dot technology to produce bright images with good contrast, but they cannot display real black and have a less wide viewing angle than OLED TVs. OLED TVs use organic material to produce a wider array of colors and have the best blacks due to individual pixels that can be switched off, resulting in a stronger contrast and better viewing angle than QNED screens.
