Question about Samsung QE77S90DAE

The Samsung QE77S90DAEXZU uses OLED technology, not QD-OLED. OLED stands for Organic Light-Emitting Diode, which allows for individually controlled pixels to produce pure blacks and bright whites, enhancing contrast and picture quality. QD-OLED, on the other hand, combines quantum dots with OLED technology, but this specific model does not use QD-OLED.
