Time-multiplexed stereoscopic display with a quantum dot-polymer scanning backlight

摘要

We fabricate a time-multiplexed stereoscopic display, which is composed of a quantum dot-polymer (QDP) scanning backlight, 120 Hz liquid crystal display (LCD), and shutter glasses. Blue LEDs, which can excite QDP film to produce white light, are adopted to replace the traditional white LEDs. The QDP scanning backlight, LCD, and shutter glasses can be controlled by the synchronization signal and work together, enabling viewers to obtain parallax views. Crosstalk is about 1%, and luminance through the shutter glasses is higher than 150 nit. The color gamut can be widely extended to 77.98% rather than the traditional 55.75% in the ITU-R Recommendation BT. 2020 (Rec. 2020) color space, due to the excellent properties of QD material.
