The acronym ‘OLED’ stands for Organic Light-Emitting Diode - a technology that uses LEDs in which the light is produced by organic molecules. These organic LEDs are used to create what are considered to be the world’s best display panels.
OLED displays are made by placing a series of organic thin films between two conductors. When an electrical current is applied, a bright light is emitted. A simple design - which brings with it many advantages over other display technologies.
OLEDs enable emissive displays - which means that each pixel is controlled individually and emits its own light (unlike LCDs in which the light comes from a backlighting unit). OLED displays feature great image quality - bright colours, fast motion and most importantly - very high contrast. Most notably, “real” blacks (that cannot be achieved in LCDs due to the backlighting). The simple OLED design also means that it is relatively easy to produce flexible and transparent displays.

So to recap.
OLED TVs use a technology where each pixel emits its own light, unlike traditional LED or LCD screens that require a backlight. This self-emitting pixel technology results in stunningly accurate colours, deep blacks, and a high contrast ratio.
Self-Emitting Pixels:
OLED stands for Organic Light Emitting Diode. Each pixel in an OLED TV is a tiny light source that can turn on and off independently. This means no backlight is needed.
Perfect Blacks:
By individually turning off pixels in dark areas, OLED TVs can achieve incredibly deep blacks and a high contrast ratio.
Improved Contrast:
The absence of a backlight allows for a more precise and accurate display of colours and contrast, resulting in a more immersive viewing experience.
Thin and Lightweight:
Without a backlight, OLED TVs are significantly thinner and lighter than traditional LED or LCD TVs.
Fast Response Times:
The individual pixel control allows for very fast response times, making them excellent for gaming and fast-motion scenes.
Wide Viewing Angle:
OLED TVs offer excellent viewing angles, meaning colours and contrast remain accurate even when viewed from off-centre positions.
Samsung, Sony & LG all make OLED TVs.
So what's QD-OLED?
QD-OLED TVs combine the benefits of both Quantum Dot and OLED technologies. They utilize individual pixels that light up to create images, like OLED, but also use Quantum Dots to enhance colour accuracy and brightness, like QLED / QNED.
This results in a TV with the deep blacks and perfect contrast of OLED, plus the vibrant colours and increased brightness of QLED / QNED.
Samsung & Sony make OLED TVs.
