报告摘要：

“LCD or OLED: who wins?” is recently a hot debate. Can LCD outperform OLED in color saturation and motion picture response time? To address the color challenge, I will present quantum-dot enhanced LCDs with color gamut approaching Rec2020 while keeping high optical efficiency. To eliminate color shift and obtain high contrast ratio over a wide viewing angle, I will describe single-domain LCDs with quasi-collimated backlight and freeform engineered diffuser. To reduce motion picture image blurs, two factors play equally important roles: high TFT frame rate and fast LC response time. To achieve fast response time, I will introduce recent advances in ultra-low viscosity LC materials, and two optically isotropic LCDs (polymer-stabilized blue phase and hyper-twisted nematic) with submillisecond response time. Benefited from these promising nanotechnologies, the dawn of a next LCD evolution is around the corner.
