Quantum Dot Color Conversion for Liquid Crystal Display

Quantum dot (QD) technology has become a revolutionary approach to enhancing color quality in liquid crystal displays (LCDs). This chapter delves into the application of QD color conversion technology for LCDs, focusing on the transformative impact of display performance by integrating QDs into backlight (BL) units and color filter components. Utilizing QDs in the BL units, both a high color gamut and improved luminescence efficiency are achieved compared to conventional white light‐emitting diodes. Moreover, QD‐based color filters (QDCFs) provide precise control over primary colors, enabling enhanced color accuracy and brightness modulation. However, there are still numerous factors influencing the application of QDCF in LCDs, including the process complexity, cost, and significant contrast loss. The potential impacts of QD‐enabled LCDs on display quality, energy efficiency, and consumer experience are underscored, highlighting the path toward next‐generation display technology.
