Colorful, functional and efficient: discover the possibilities of quantum dots (QD) with QustomDot. We develop on-chip grade, RoHS compliant QD technology for future applications in color conversion.
Quantum dots (QDs) are tiny semiconductor nanoparticles that can transform UV or blue light into other pure colors. By controlling their size, we are able to determine the color emitted by the QDs. QDs can also be processed very easily through printing and coating. Many companies have already experimented with this revolutionary technology, but are limited in doing so because QDs suffer from degradation at high temperatures and light flux. QDs were therefore primarly used in a sealed and expensive sheet, and are still separated from the light source in most commercial products. QustomDot however works with a QD technology that is stable enough to be used directly on LED chips, which allows us to target new applications such as high quality microLEDs.
As we speak, the only commercially available QD technology that is stable enough to use directly on the LED chip, is based on cadmium. However, cadmium is restricted by the RoHS directive of the European Commission. The display and lighting industry therefore refuses to use cadmium-based QDs in their devices. We supply the demands of the industry and provide a solution: QustomDot has developed a QD technology that is based on non-restricted cadmium-free QDs, stable enough for on-chip usage.
The QustomDot technology is truly unique: it is the only commercially available QD technology - stable and reliable - that is cadmium-free and on-chip grade.
Our QD technology can be used in traditional LEDs for lighting and LCD displays, in miniLEDs and in microLEDs. Especially the microLED technology is revolutionary and can change the display world as we know it. With 3 microLEDs, you can form a pixel of a self-emissive display. This revolutionary type of display has all the benefits of OLED TV, offers extreme brightness, and features a large color gamut thanks to the QDs. The small size of the microLED enables us to integrate other functionalities in the display itself. There are many more applications possible for self-emissive microLED than for OLED: traditional displays, AR/VR goggles, smart watches, automotive displays, smartphones, etc. When using QDs as color conversion material, you can significantly simplify the microLED production process and reduce costs.
