Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. The color conversion films may comprise at least one of: polydimethylsiloxane hydroxy terminated, dendritic polyol or polyvinylpyrrolidone.
本发明提供了用于具有 RGB(红、绿、蓝)彩色滤光片的液晶显示器(LCD)的色彩转换薄膜,以及此类显示器、配方、前体和方法,可改善显示器在色域、能效、材料和成本方面的性能。色彩转换薄膜吸收背光照明,并以高效率、特定波长范围和窄发射峰值将能量转换为绿色和/或红色发射。色彩转换薄膜可由羟基封端的聚二甲基硅氧烷、树枝状多元醇或聚乙烯吡咯烷酮中的至少一种组成。
