Wide color gamut LCD with a quantum dot backlight.
We analyze the color performance and system efficiency of three commonly employed liquid crystal display modes with a blue LED-pumped red and green quantum dots (QDs) backlight. Based on the measured QD emission spectra, we can achieve 115% color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as conventional backlights. Next, we apply multi-objectiv...
متن کاملRealizing Rec. 2020 color gamut with quantum dot displays.
We analyze how to realize Rec. 2020 wide color gamut with quantum dots. For photoluminescence, our simulation indicates that we are able to achieve over 97% of the Rec. 2020 standard with quantum dots by optimizing the emission spectra and redesigning the color filters. For electroluminescence, by optimizing the emission spectra of quantum dots is adequate to render over 97% of the Rec. 2020 st...
متن کاملProspects of quantum dots-based liquid crystal displays
We report a systematic photometric study of LCD based on quantum dot (QD) backlight, and find the optimal emission spectrum combination in terms of system efficiency and wide color gamut. A QD-based LCD has potential to achieve 120% AdobeRGB color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as conventional backlights. Moreover, we present a trans...
متن کامل19.3: Distinguished Student Paper: Quantum Dots-enhanced LCD Color and Optical Efficiency
We optimized the emission spectrum of a quantum dot (QD) backlight and achieved ~140% color gamut in CIE 1976 color space. The QD-based LCD not only exhibits a wide color gamut but also improves the optical efficiency. Our systematic photometric analysis provides useful guidelines to further optimize the QD backlight design.
متن کاملColor performance of an MVA-LCD using an LED backlight
Ruibo Lu (SID Member) Xiangyi Nie Shin-Tson Wu (SID Fellow) Abstract — The color performance, including color gamut, color shift, and gamma curve, of a multidomain vertical-alignment (MVA) liquid-crystal display (LCD) using an LED backlight are calculated quantitatively. Simulation results indicate that an LED backlight exhibits better angular color uniformity and smaller color shifts than a CC...
