Explaining the difference between QLED and OLED Televisions

 LG named their high end television models as OLED while Samsung branded their top models as QLED tv. They look almost similar but they are whole different technologies.

Basic difference are listed as follows :-

  • OLED TVs use panels of OLEDs to both generate and illuminate the picture while QLED TVs use LCD panels and LED backlight arrays, like many high-end LED TVs.
  • Each pixel on an OLED panel is produced entirely by the OLEDs themselves, determining the color of that pixel and causing it to produce light while QLED TVs use Samsung’s Quantum Dots technology for its LCD panels. Quantum Dots are nanoparticles that emit or alter light at different frequencies when exposed to electricity.
  • OLED TVs are often described as having “infinite” contrast—no matter how bright the screen can get, the black level is always zero while QLED TV contrast is still a big concern—the technology doesn’t appear to produce the perfect black levels that OLED panels can.
