Technology evolves at a phenomenal speed and this applies to all areas, including TVs and their technologies. Thus, a few years ago, we discovered OLED TVs, jewels of technology, offering images in vibrant colors. But as we say, technology continues to evolve and now we have a new technology available: the Neo QLED. But then, what to choose between OLED and Neo QLED? Let’s do a check in.
OLED a light source for TVs
Organic Light Emitting Diode or OLEDis a technology that allows pixels in a TV to generate their own light to form a visible image.
Until now, the light from the pixels of a TV was provided by an external light device, LED or Mini-LED for LCD televisions, or by a chemical reaction for plasma sets. From now on, the light that illuminates the pixels of a TV can be provided by OLED components.
The OLED diode is made of different very thin layers that contain organic materials (based on carbon):
- the ETL layer “Electron Transport Layer”, it transports electrons
- the HTL layer “Hole Transport Layer” it carries “vacuums” that do not contain electrons
- the EML layer “Emitter Layer” the place where the electrons and the “vacuums” will join
OLED TV advantages
- a black level rendering and a high contrast ratio, thanks to the possibility of completely turning off the pixels
- good color rendering, thanks to a full scale of shades of gray
- a low response time, which can drop below 0.1 ms
- numerous viewing angles and brightness, the light being emitted directly at the pixel level.
- low energy consumption.
- possibility to create transparent and flexible screens
- OLED TVs can be very thin
The Neo QLED a technology developed by Samsung
QLED technology is based on a quantum dot filter placed on a slab and backlit by LEDs.
Quantum dots are cadmium selenide nanocrystals, tiny semiconducting three-dimensional structures that react to light by producing fluorescent light.
Depending on the size of the quantum dots, the length of the light wave varies to restore very fine color shades that are very close to reality.
Samsung has therefore created Mini LEDs 40 times smaller. For the same screen size, Neo QLED televisions have thousands of additional LEDs grouped together for some models in more than 800 zones and we obtain a really much more precise backlight.
Image contrast and sharpness reach levels never before seen on LCD screens. Since nanocrystals are inorganic, Neo QLED TVs are also much more durable and less energy consuming.
Two other innovations play a key role in the level of precision:
- The Adaptive HDR10+ functionwhich uses a light sensor to analyze ambient lighting conditions.
- Quantum HDR (High Dynamic Range) technology which produces a dynamic cartography.
No more loss of contrast and detail, regardless of the level of ambient light and offer peak brightness up to 4,000 nits. With Neo QLED technology, it’s the guarantee of a most immersive experience, even on large screens. Sparkling and controlled luminosity, deep contrasts and an image without installation constraints. Such are the promises of this new technology.
The benefits of Neo QLED TVs
- high brightness
- very few reflections
- vibrant colors
- suitable for bright rooms
- fast response time for video games
OLED or Neo QLED, which TV to choose?
It all depends on what you want to use it for. QLED technology comes out on top, offering higher brightness, longer life, larger screen sizes and lower prices.
In addition, Samsung has taken particular care the video game part of its new televisions. The biggest promise is in a number: 144 Hz, the new maximum frequency for game mode!
For sports viewing, the OLED is more suitable, since the viewing angle is almost perfect. In addition, motion blur is reduced. OLED technology, on the other hand, has a better viewing angle, much deeper black levels, uses a lot less power, and might even be better for your health.
However, OLED technology remains expensive and the lifespan of televisions is much shorter than QLED models
