Special Issue Information

Dear Colleagues,

Quantum Dots (QDs) have many unique physical and optical properties, such as high photoluminescence quantum yield, tunable emission over the entire visible spectral region, narrow emission spectrum, and high color purity. QDs have become a suitable candidate material in the display field and have great potential to replace the traditional phosphor powder and increase the LCD color gamut range.

Micro-LEDs are an emerging flat panel display technology. As the name implies, micro-LED displays consist of arrays of microscopic LEDs forming the individual pixel elements. Applications include near-eye displays, wearable devices, head-mounted devices, visible light communications, computer monitors, biomedical devices, and projectors, which benefit from the clear advantages of micro-LED displays in brightness and saturation, as well as high display quality, even in high-intensity ambient light.

In this Special Issue, we would like to invite all papers related to the science and technology of Quantum Dots (QDs) ranging from materials research, device structure and properties, device applications for micro-LED displays, manufacturing, and high-color-gamut displays using QDs. Research in the following fields is particularly welcomed:

  • QD or micro-LED displays;
  • Energy applications;
  • Bio-applications;
  • Mechanical resonators;
  • Perovskite QDs;
  • Cd-free QDs;
  • Optoelectronics, such as lasing, lighting, micro-displays, and AR/VR.

Micro-LED display technology has emerged as a significant area of interest, with numerous research teams globally approaching it from various disciplines. Concurrently, several enterprises have initiated production or plan to invest in equipment manufacturing. However, the industry currently lacks standardized production processes for Micro-LED displays. This is largely due to major manufacturers adapting their equipment and material choices to suit their specific product applications. Nevertheless, advancements in recent years and developments within the supply chain reveal a gradual convergence of technology across the sector. This review paper aims to provide an investment and cost analysis perspective of the current industrial landscape of Micro-LED technology. It examines key aspects such as the selection of bonding materials, differences in driving modes, considerations for native RGB versus color conversion, strategies for cost optimization, market information and unique differentiation features of Micro-LED displays. To make this paper accessible to a broader audience, including those outside the electronics industry, key technical processes are described with clear explanations and the relevant context.
