A quantum dot display is an electronic display device which uses tiny semiconductor dots, also called quanta, to generate pure red, green, or blue light. These dyes are made from materials such as indium gallium selenide (IGE) and gallium nitride (DNG), which have the same color properties as red, green, or blue. This type of display was first developed by scientists and is now being used in LED (light emitting diode) bulbs. In addition to their use in lighting up an entire room, they can also be used for displaying short messages on medical equipment, computer screens, and even in vehicle headlamps. Here we will take a look at some of the history of this technology and how it has evolved over the years.
Quantum dot displays have been around for quite some time already, but they were first developed for use in optical fiber. It was discovered that using these special fibers could produce very clear and crisp images that were sharper and more vibrant than ordinary dot-less display devices. In fact, they outperformed all other types of display technology, which led to many people calling them "quantum dots". Now that we are more accustomed to seeing these dots in LED lamps, we may begin to understand why they are becoming so popular with electronics today. This article will take a quick look at how this technology has evolved and where it is headed.
Originally the dots were placed on the surface of the glass panel which was laminated on top of a substrate. The laminated surface was transparent to the human eye, but not so transparent to the infrared light that the light had to pass through. Because of this light blocking quality, the dots had very limited color processing capabilities. Another disadvantage of this type of display was that it tended to reflect back most of the light which came through, resulting in colors being displayed which looked very similar to the light that was reflected back from an ordinary fluorescent lamp. This was one of the main reasons why this type of technology didn't catch on as quickly as some other types of display technology.
Quantum dots then emerged with the development of new technology which allowed them to be applied to a surface which did not have this light blocking quality. These new technologies allowed for the creation of a dot panel which contained millions of tiny dots. These dots were then lit up using a small amount of electricity. Once lit up, the dots immediately started to change colors as the light was shined upon them. What the early designers were hoping to accomplish was to use this ability to create a very clear and bright display which was more vibrant and colorful than other types of displays.
With the advent of new technologies and new ideas, this vision became a reality. Companies like Dell and HP soon saw the potential of a uniform display which used the Quantum Dot technology. They began to use these lights like fluorescent lights in their computers and laptops. This was not a very popular choice because many people felt that these newfangled technologies weren't very efficient and would not stand up to the normal demands of the human body. Luckily, those views are changing. Now we see display systems that feature Quantum Dot lights which provide even brightness and a dazzling quality.
So what is it about Quantum Dot Display technology that makes it so special? To put it simply, this is a unique form of technology that incorporates the power of light into a new kind of display. Most of us are familiar with the traditional fluorescent lights that line the top of computer monitors. These types of lights are the closest thing we have to "free energy" in terms of a light source. They are extremely efficient at producing light, but they are far from being all that bright and vibrant. This is because the phosphors in the tubes of these display systems can only absorb so much energy before they are wasted.
The Quantum Dot System uses a different approach. Instead of using fluorescent tubes, the dots contain a cluster of carbon or metal atoms that absorb photons when they are struck by these lights. When the light strikes them, they become excited and release energy. The more of these particles are excited, the brighter the dot display will be. And the more emitters there are, the broader and brighter the dot will be, up to a point.
The biggest advantage of Quantum Dot technology comes from the efficiency with which the system operates. As we have mentioned, this new type of light source is based on the collective excitation of millions of tiny emitters. Each of these particles is charged differently, and that allows the lights to be put together in millions of different ways. Because of this, Quantum Dot displays units are able to achieve high efficiency while consuming much less electricity than their fluorescent counterparts.
