Quantum-dot screens, also known as QLED (Quantum dot LED), are essentially a new sort of LED-backlit LCD. In order for these panels to respond to light and electricity, they make use of extremely small phosphorescent crystals. The "nanoparticles," which have a size of less than 500 nanometers, have the ability to glow in a variety of colors, each of which is precisely specified by the amount of atoms contained within. And instead of using backlights that are a pure white color, the quantum dots, when struck by blue light, emit either red or green light. This implies that the colors you see will be significantly more realistic and highly saturated than what you would see on an average LED panel.
How Does Quantum Dot Work?
Every pixel on the screen can produce either red, green, or blue light, and in certain cases a mixture of all three colors. Wavelengths are what determine how accurate the color of each pixel is going to be. Quantum dots may also be easily adjusted to their predetermined size in order to emit light of a variety of different wavelengths, which results in superior color generation.
Quantum dots are often arranged in a film, although they can also be contained in tubes. Tubes are the less popular option. The sheet is then positioned between a blue LED unit and color liquid crystal display (LCD) filters before being inserted. When the quantum dots are illuminated by the blue LED, they begin to glow in a red and green color. When these three colors are mixed together, they generate the "purest" kind of white light. The white light provides the color filters with a source that is more precise, which enables them to efficiently and precisely filter out the three hues.
The placement of the quantum dots in a QLED display is depicted in the diagram that can be found above. Gradations of red, green, and blue are produced as a result of light emitted from a blue LED light source that then travels through a film enhancement layer. After passing through the liquid crystal display panel (LCD) and the color filter glass, the various colors of light arrive at the screen, where they are used to produce an image.
Advantages of Quantum Dot Technology
The added quantum-dot layer brings your monitor a whole host of benefits.
Precise Color and Higher Peak Brightness
Since the quantum dots can be made to emit a specific quantity of light, this indicates that the color that is created will be more true to life. The nanoparticles have the ability to render colors across a wider spectrum at the highest possible brightness without sacrificing saturation. This makes it possible for photos to be displayed clearly even in extremely well-lit rooms. In addition, brightness is an essential component of a high dynamic range (HDR) experience, as it ensures that all of the nuances of light and color depicted onscreen appear more accurate to real life.
Better Energy Efficiency
Quantum dots only require a small amount of energy to work, and this can be achieved by a single blue light. In fact, they can produce a 30 percent increase in brightness while using about 30 to 50 percent less power. This reduced power consumption results in lower costs. Unlike conventional LCDs that waste energy combining and balancing different colors, QLED screens emit precise colors for improved energy efficiency.
Longer Lifespan and Low Burn-In
As QLED displays are based on existing LCD technology, they benefit from having a longer lifespan as they rely on modern and energy-efficient backlighting. Quantum dot technology also does not degrade over time, meaning QLED displays are less prone to burn-in. Burn-in is when part of an image will appear like a “ghost” on the screen and would not go away. This only happens when each self-lighting pixel dims over time.
Versatile Sizes and Thinner Panels
Since quantum dot technology is easier and less expensive to produce, QLED displays can be made in a greater range of sizes and can go as large as 98 inches. They can also be applied on large, thin, and flexible LCD panels, making the QLEDs easy to transport and install.
Organic light-emitting diode, often known as OLED, is most likely another type of display technology that you are familiar with. Organic light-emitting diodes, or OLEDs, are made up of organic molecules that light up when electricity is applied. Electroluminescence is the term used to describe this phenomena.
The operation of an OLED display is depicted in the diagram that follows. The positively charged anode layer is placed on top of the negatively charged cathode layer, creating a sandwich that contains the organic emissive layers. In order to generate colored light, an electric current will move through each layer, beginning at the cathode and ending at the color filter.
Every pixel in an OLED display is its own source of light, in contrast to a QLED, which relies on backlights. Due to the fact that they degrade more quickly, the organic materials that make up an OLED panel often have a higher production cost and a shorter shelf life. The self-emitting pixels of an OLED do not generate the same level of brightness as those of a QLED, but they are capable of projecting the darkest black, which results in deeper contrasts. When it comes to image preservation, OLEDs are far more prone to burn-in than other types of screens. However, it is essential to keep in mind that in addition to providing excellent viewing angles, rapid response times, and colors that are nearly perfect, OLED displays also offer.
Are QLED Monitors Any Good For Gaming?
Televisions are the most common type of display that utilize quantum dot technology. However, the capabilities of a QLED can also be translated onto a monitor, making it an excellent choice for use in gaming due to its versatility. Players prefer to compete using gaming displays that are able to create a more immersive viewing experience, and this is especially true in the realm of esports. The picture quality of games created with quantum dot technology is far more lifelike, with colors that are more bright and contrast that is more pronounced.
In the event that the gamer has to activate HDR video, QLEDs provide darker blacks, a wider color gamut, and more brightness than a standard panel would. And due to the additional capabilities that QLED monitors are equipped with, such as sync technology and black level stabilization, they frequently give superior technical performance than televisions. This enables players to breeze through graphically demanding games while still being able to see each and every piece in mesmerizing detail.
Final Thoughts
It is abundantly evident that displays utilizing quantum dot technology offer imagery that is rich in color in addition to numerous other advantages. When viewed through the eyes of a gamer, the conventional viewing experience can be transformed into a cinematic pleasure thanks to quantum dot screens. It is important to note that the technology of quantum dots is always being improved in order to bring about displays that are friendlier to the environment and have improved color performance, increased brightness, and possibly even reduced pricing. As a result, it is only a matter of time until QLED gaming monitors become the norm for all gamers.
