Quantum Dot (QD) Inks

Quantum dot (QD) inks are advanced functional materials designed for next-generation optoelectronic and display technologies. These inks contain semiconductor nanocrystals known as quantum dots, which possess unique optical and electronic properties due to quantum confinement effects. By precisely controlling the size and composition of these nanocrystals, QD inks can emit highly pure and tunable colors across the visible spectrum.

QD inks have become key enabling materials in modern display manufacturing, playing an increasingly important role in the development of high-performance visual devices. Their excellent color purity, high brightness, and tunable emission characteristics make them particularly suitable for use in high-performance televisions, monitors, mobile devices, and emerging micro-display technologies.

Key Features

QD inks are engineered to provide both excellent optical performance and reliable processing characteristics. One of their most important features is the ability to deliver highly saturated colors with narrow full width at half maximum (FWHM), enabling displays to reproduce more vivid and accurate images. This property allows devices to meet or exceed advanced color standards such as Rec.2020, making them highly attractive for premium display applications.

Another advantage lies in their superior stability and process compatibility. Modern QD ink formulations are designed to maintain uniform dispersion of quantum dots, preventing aggregation and ensuring consistent optical performance during storage and printing. They also demonstrate excellent jetting behavior and compatibility with various printing systems, allowing manufacturers to precisely deposit color conversion layers or emissive materials onto substrates. Furthermore, after curing, the resulting films typically exhibit low shrinkage, strong adhesion, and high structural integrity, all of which contribute to improved device reliability and long-term performance.

Our Products

• QLED Inks

Quantum dot light-emitting diode (QLED) inks are specially formulated materials used in the fabrication of quantum dot light-emitting diode devices. These inks contain high-quality quantum dots dispersed in carefully optimized solvents and additives to ensure excellent dispersion stability and printing performance. When used as emissive layers, QLED inks can produce bright, highly saturated colors with narrow emission spectra, enabling displays with superior color purity, high brightness, and improved energy efficiency.

• QDCC Inks

Quantum dot color conversion (QDCC) inks are designed for use in color conversion layers within display panels. In this configuration, quantum dots absorb incident light and re-emit it at specific wavelengths, generating highly pure colors. QDCC inks offer excellent printing stability, uniform film formation, and reliable optical performance after curing. These features make them ideal for advanced display technologies such as QD-LCD, OLED with color conversion, and emerging micro-LED displays.
