Optical characteristics of TN-LCD combined with inkjet printed quantum dot color pixel convertor

To overcome strong viewing angle dependency of TN-LCD, we introduced a quantum dot/rod color convertor. We fabricated quantum rod-based color conversion subpixels by ink jet printing and stacked on a twisted nematic liquid crystal panel to improve not only its viewing angle but also color gamut. The resulting color conversion layer produced a very wide viewing angle and the panel covers more than 80% of the BT.2020 standard color gamut.
