Perovskite Nanoparticles for Display Applications

Vibrant, Efficient, Low-Cost Emitters:

Background

Perovskite nanoparticles are revolutionizing display technologies by down-converting some of the light from the blue LED backlight to narrow-band red and green components which results in much improved color gamut, color temperature and color rendering. Perovskites are renowned for their high efficiency, color quality, and tunability.

Our Innovation

The researchers developed a facile, low-temperature solution-process synthesis of tunable 2D organic-inorganic hybrid perovskite nanostructures. Confined 2D perovskites demonstrate enhanced optoelectronic properties compared to the bulk (3D) material.

Advantages

• Low cost, high efficiency direct and tunable bandgap
• Perovskite nanoparticles can be formulated as inks and can be inkjet printed

Opportunity

Perovskite emitters have excellent performance characteristics and compete favorably with OLEDs and QDs while benefiting immensely from the investments made in QD technology to educate the market and force the adoption of narrow-band down-converters for improved image quality.

• Due to unique technological approach, researchers enable a differentiated product stepping away from the crowded QD space.
• Both the display and general lighting industries have a big market
• Other relevant applications includes:  color filters, sensing, lasing, and LEDs where the perovskite is the electroluminescent active layer.
