what is qled

QLED stands for Quantum Dot Light Emitting Diode. It is a type of television that uses quantum dot technology, which is what makes it different from conventional LED TVs. Quantum dots are semiconductor nanocrystals that can produce pure monochromatic red, green, and blue light. They are used in LCD backlights or display color filters. QLED TVs use a blue LED light source and a film embedded with tiny quantum dots, which are sandwiched between the other layers of the LCD panel, replacing the color filter in front of the LED backlight. This technology enhances the High Dynamic Range (HDR), which is an essential component of picture quality, providing crisp and rich images. QLED TVs tend to have a higher peak brightness, a long lifespan, and are well-suited for bright rooms. On the other hand, OLED TVs tend to have better contrast and color accuracy, deeper blacks, and wider viewing angles.
