Quantum dots, a technology that has been making waves in the display industry, are tiny semiconductor particles that emit light when stimulated by an external source. These nanocrystals, typically measuring just a few nanometers in diameter, have unique optical and electronic properties that make them highly desirable for use in display technology.
The concept of quantum dots was first introduced in the early 1980s, but it is only in recent years that they have gained significant attention for their potential applications in displays. Traditional displays, such as liquid crystal displays (LCDs), rely on a backlight to illuminate the screen. This backlight emits white light, which is then filtered and manipulated to produce the desired colours. However, this process is not very efficient, as a significant amount of light is lost in the filtering process.
