Abstract
Liquid-crystal display (LCD) with patterned quantum dot (QD) film and short-pass reflector (SPR) was proposed and has an advantage for dramatically enhancement of optical efficiency compared to LCD prepared with a mixed QD film (reference). In proposed LCD structure, the optical power in blue, green, and red color was increased by 869%, 256%, and 85% compared with the reference, respectively. This enhancement comes from the two facts; 1) blue backlight is converted to green or red light separately by each patterned green or red QD film entered directly to each CF without any different color cut, 2) SPR reflects the backward emission of QD to forward direction, preventing the absorption loss of backward emission by back light unit. Additionally, we obtained high color gamut of NTSC 125% in our proposed LCD using a broad-band CF while maintaining the maximum optical intensity with relatively high CF transmittance.
