In our recent blogs about the curved Samsung gaming monitors, we have numerous times mentioned the amazing Quantum Dot technology the monitors come with. As does the insane, 49-inch Samsung CHG90, that arrives today. To celebrate the launch of this monitor, we decided to enlighten you with more detailed information about some of the most important features, starting with the Quantum Dot technology. So, what is this technology all about?
To start off, it is important to realise that Quantum-Dot TV is similar to an LED-backlit LCD TV, however, an upgraded version. The image itself is created just like it is on an LCD screen, but the Quantum Dot technology drastically enhances the colors. On an LCD TV, you have a backlight system, which is a bank of LEDs mounted at the edge of the screen or immediately behind it. On most LCD TVs, these LEDs emit white light, but those in Quantum-Dot TVs emit blue light. Technically, both LEDs have blue light, but those in LCD TVs are coated with a yellow phosphor, therefore emitting white light.
Here’s where the Quantum Dot makes the big difference. The blue light of the LEDs drives the blue hue of the image, but the red and green come from the quantum dots. The dots are either in a tube next to the blue LEDs, also known as a ‘’quantum rail’’, or in a sheet on top of the light- guide plate. The Quantum dots have a main job, which is emitting one main color. When the dot is struck by light, it glows in very specific color that is tunable. And, in combination with the light of the blue LEDs, these quantum dots will glow with insane intensity, creating much more vivid and deeper colors.
As said before, most of the Samsung monitors we have recently wrote about come with this amazing new technology, as does the 49-inch beast, the Samsung CHG90. This helps creating an unprecedented gaming or viewing experience, or massively benefits professional visual designers, due to much more realistic colors.
