The best displays are usually based on their technical specifications and how effectively they can produce visuals. For instance, Samsung uses nanotech in displays to generate rich-filled, vibrant visuals. Samsung's Quantum Dot Technology makes flat-panel LED displays more visually appealing by boosting colors and implementing higher brightness levels to use High Dynamic Range (HDR) technology in the best way possible.
Quantum Dots, referred to as human-made semiconductive nanoparticles, are placed onto sheets of fibers, films, glass, and electronics that form a liquid crystal display. Lighting up these Quantum Dots causes them to emit specific-colored lights. Samsung's R&D investment allowed the tech giant to become a Quantum Dots production and display market leader with its Quantum LED (QLED). Displays featuring Quantum Dots are also much better than OLEDs due to the lower cost, along with the fact that they don't have the same technical issues and limitations present in OLEDs. Originally used in TVs, Quantum Dots tech is now commonly deployed in digital signage.

These Quantum Dots are two to ten nanometers in size, and that size determines which wavelength and color they emit. So after they get exposed to a light source, the dots emit a specific bandwidth color. In this case, 2nm Quantum Dots produce blue light, while those measuring 3nm and 7nm produce green and red light, respectively.
These Quantum Dots are placed on a layer film sheet in front of the LED backlight lighting up an LCD. The light travels through the LCD stack, allowing the Quantum Dot color filter to enhance the LCD while it provides a highly saturated range of colors than ever before. Due to their pure monochromatic light production capabilities, a QD-OLED panel has enhanced color production versus OLED displays. Even then, each comes with key visual differences.
Technically speaking, LCDs illuminate through integrated LED lighting arrays, while OLEDs have pixels working as their own light. These technologies provide a wide range of colors that display stunning visuals for the viewer. Although Quantum Dots reproduce those colors at full brightness, OLEDs colors become compromised, which affects the spectrum. Samsung's QLED displays peak brightness can reach 4,000 nits, a level that surpasses an outdoor display's requirement to offset the glare from sunlight.
QLED displays also emit consistent color expression in their lifetime. Meanwhile, OLED color expression dims over time throughout its operational use. Additionally, an OLED screen at high brightness may experience burin-in if an image or text stays on for a long time.
QD-OLED displays efficiently use backlight due to minimal loss. As a result, they have higher brightness levels than WRGB OLED displays. As demonstrated in different tests, quantum dot displays emit more brightness than WRGB OLED displays. Plus, QD displays have richer colors thanks to their quantum dots and generated monochromatic color. For instance, reds have a deeper appearance than OLED displays. While OLEDs present better viewing angles than LCDs and QLEDs, they're still not as good as QD-OLEDs, which offer higher color accuracy. Pixel burning doesn't occur as often in QD displays since they have higher brightness efficiency.
Businesses and brands focus more on visual quality over size and pixel counts. After all, Full HD, Ultra HD, and others are more visually appealing when displays provide excellent detail and color depth. AI-powered machine learning supports Samsung's QLED technology, allowing it to Full HD and 4K UHD to 8K resolution without sacrificing quality.
