A Quantum Dot Display is a type of screen technology that uses tiny semiconductor particles called quantum dots to produce vibrant colors. These dots emit specific colors of light when exposed to a light source, typically a LED backlight. This allows for improved color accuracy and brightness compared to traditional displays. In a Quantum Dot Display, the quantum dots are often placed in a film layer that sits between the backlight and the screen. This setup enhances the overall viewing experience by providing a wider color gamut and better energy efficiency, making it a popular choice for televisions and monitors.
