QD-OLED Features: Quantum Dot
One of the most important points of future screens is the possibility for each pixel to have its own lighting, which cannot be achieved with conventional LCD screens, therefore, one of the keys to QD-OLED screens from Samsung is that they work like MicroLEDs.
In other words, if, for example, we have a screen with 4K resolution and, therefore, 8.3 million pixels, then with QD-OLED technology we have 8.3 million light sources that can be controlled individually, one at each pixel on the screen. The result? An extremely faithful representation not only of colors, but also of their luminance, one of the weak points of LCD screens.
Also, because the QD panel emits light in all directions, it means we can see the panel from many more viewing angles than conventional screens, making this panel ideal for TVs, wherever it will go. first implement.
Better color rendering
Behind the Quantum Dots panel is an OLED panel, but it only emits blue light, since the color change of each pixel is performed by the QD panel. This results in better color representation according to Samsung. This is one of the most important improvements of this technology, because it achieves in this aspect an incremental improvement in the representation of colors, well above what the various manufacturers have offered until now, including those of OLED screens.
Advantages inherited from OLED
Using OLED panels instead of LCD for Samsung’s QD display brings a series of benefits to organic LEDs. The first concerns the contrast: if we look at the different LCD type panels, we find values of 1000: 1 for TN and IPS and 3000: 1 for VA, where in the case of QD-OLED we can speak of values of 1,000,000:1.
This gives these displays an excellent ability to reproduce colors in high dynamic range or HDR without the typical issues that arise when combined with LCDs that have much lower contrast. Therefore, the window of colors these displays can represent is much higher, making them ideal for use in graphic design and image editing.
We also can’t forget the brightness, measured in nits. Currently, OLED panels can reach 800 nits, but QD-OLED technology can go up to 1000 nits. This will mean the appearance in the future of a specification of the Display HDR True Black standard much higher than the current one to take advantage of the capabilities of this new technology.
QD-OLED and response time
One of the disadvantages of LCDs of any type when it comes to needing a backlight is that it increases response time, thus affecting the clarity of movement of objects on the screen. ‘screen. One of the benefits of QD-OLED displays is that the circuit produces light as needed from the OLED panel that makes up the display. The advantage? It doesn’t take long to control the light and the result is extremely fast response times that hover under 1ms on a gray to gray transition.
Less eye strain
The so-called blue light eventually produces eye fatigue and with it long-term headaches. It is not a problem that television users suffer from because of the distance at which they usually use their screens, however, it is important if we work daily with our computer and it is that those of us who spend many hours in front of the PC ending up with our heads saturated.
One of the benefits of screens with Samsung’s QD-OLED technology is that it reduces the amount of harmful blue light that reaches our eyes. This is achieved by varying the spectral blue light peak outside the 415-455 nm region. It won’t be the first technology designed to reduce this problem that we will see in the years to come, as other manufacturers are working on similar solutions, but for those of us who work daily with our screen a few meters away, it is appreciated.
One of the biggest problems with many TVs is when a light source hits the screen glass and it acts as a mirror in addition to displaying the image on the panel. Samsung has added an anti-reflective coating to its QD-OLEDs, ensuring that outside light doesn’t directly affect the image.
Without a doubt, we are talking about a series of improvements that will soon reach the brand’s televisions and that could begin to be implemented in professional and gaming monitors in a short time.
