Experts Review:

Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Quantum Dot Backlight technology is emerging as a novel backlight source that could help to increase the color performance of LCDs. QDs are composed of nanoparticles with diameters of 5–20nm. When charge carriers (electrons and holes) are con- fined to such small particles, the larger bandgap of the surrounding material creates a barrier. The discrete energy levels that arise as a result of this barrier consequently dictate the material properties.

Quantum Dot Backlight with narrow emission line-widths, tunable wavelength, and high quantum efficiency, offer the ideal backlight spectra for LCD displays. When combined with today’s high efficiency blue LEDs, quantum dot films can enable 20% higher power efficiency for sRGB color gamut displays by using higher transmission color filters. Furthermore, quantum dot films are capable of delivering wide color gamut solutions (e.g., Adobe-RGB and DCI-P3) without any penalty in power efficiency compared to today’s sRGB displays using white LEDs.

Quantum Dot Backlight comprise a new class of material that can be tuned to emit light very efficiently at precise red, green, and blue wavelengths, thus creating an ideal light spectrum for LCDs. Unlike conventional phosphor materials, quantum dots, which are just nanometers in diameter, can be fabricated to convert short-wavelength light (i.e., blue light) to nearly any color in the visible spectrum.

Quantum Dot Backlight for display applications are generally made from elements such as cadmium selenide or elements such as indium phosphide. They are typically synthesized via solution chemistry in high-boilingpoint solvents using precursors and ligands that bind to the surface of the dots. By controlling different synthesis conditions, e.g., precursor and ligand concentrations and the temperature and time of the reaction, quantum dots of different sizes can be obtained.

Most of today’s LCDs use white LEDs as the backlight illumination source. These white LEDs have a blue LED chip combined with a broad-band yellow phosphor, Ce-doped YAG. The red, green and blue primary colors required by the LCD are achieved by using color filters with band-pass in the red, green, and blue spectral region, respectively. Inherently, yellow phosphor is not well-suited for green and red primary colors due to the low spectral weights in the green and red regions.
