OLED – Organic Light-Emitting Diode – is a type of display technology that makes it possible to reach dark black levels from ultra-thin screens while, at the same time, making TVs more efficient and eco-friendly.
Here’s how OLED technology works: an organic, carbon-based film is placed between two conductors and, when an electrical current is passed through, it emits light.
What does QLED stand for?
The LED part of QLED, as most of you will know, stands for light-emitting diode - the lighting system used in the vast majority of LED/LCD TVs for years now. The important bit of QLED is the Q, which stands for Quantum Dot.
Samsung introduced the QLED name for Quantum Dot TVs with its 2017 TV range.
Quantum Dots offer a different way for screens to produce color instead of the usual inefficient and limited combination of white LEDs and color filters.
The dots in question range between two and 10 nanometers in diameter, and produce different colors depending on their size. For instance, the smallest dots focus on blue, the larger ones focus on red.
The key point about Quantum Dots is that they’re able to produce more heavily saturated and precisely defined primary colors from blue LEDs than you can get from the relatively broad and thus imprecise light spectrum associated with white LEDs.
LCD
LCD (liquid crystal display) is the technology used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.
LED
which stands for “light emitting diodes,” differs from general LCD TVs in that LCDs use fluorescent lights while LEDs use those light emitting diodes. Also, the placement of the lights on an LED TV can differ. The fluorescent lights in an LCD TVare always behind the screen.
