Key Patent Report - Quantum Dot Display - 2013

The quantum dot recently emerged as a next-generation display material. Quantum dots, whose diameter is just a few nanometers, are semiconductor crystals. The smaller its particle is, the more short-wavelength light are emitted; the larger its particle is, the more long-wavelength lights get emitted. Considering that there are more advantages with the quantum dots over conventional light sources, it is not surprising that the quantum dot display gains a lot of attention.
 
The quantum dot display consumes lower power and has a richer color than the conventional OLED. In addition, the white light produced by quantum dots has high brightness and excellent color reproduction, raising its potential to replace the backlight unit (BLU) using the LED. Not surprisingly, leading companies in the display industry are accelerating to secure relevant technologies.

“Key Patent Report – Quantum Dot Display” covers patent application trends and an in-depth analysis. It will be a great help for those who are interested in the patents on quantum dot displays.
