RayVolution® Oval glass tubing for high-end color enhancement in LED backlight displays

Product Information

Currently, quantum dot (QD) based techniques are the leading innovation for enhanced color space for displays. The optimization of the color gamut is one of the main drivers for current LCD display innovations. SCHOTT RayVolution® is one of the most efficient solutions for QD encapsulation into capillary optics. The oval shaped fine tubing offers tightly controlled dimensions which guarantee extremely high accuracy for the color of the Quantum Dots (QD) optics. Precisely controlled dimensions of this oval capillary also facilitate an efficient assembly into the backlight unit. High precision RayVolution® tubing is made available through a patented process.
