Introduction to Quantum Dots and Quantum Dot Displays
Quantum dots (QDs) are semiconductor nanocrystals with unique optical and electronic properties due to their size, which is typically in the range of 2-10 nanometers. These properties make them highly attractive for a variety of applications, particularly in display technologies. Quantum dots can emit light of specific wavelengths when exposed to UV light, and the color of the light depends on the size of the quantum dots. This tunable light emission capability makes quantum dots a critical component in the next generation of display technologies.

Working Principle of Quantum Dot Displays
Quantum dot displays leverage the light-emitting properties of QDs to produce vibrant colors and enhanced brightness in screens. In a quantum dot display, blue light from a backlight unit excites the quantum dots, which then emit light in the desired color spectrum. This results in a display with a wider color gamut, better brightness, and higher energy efficiency compared to traditional liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays.
