【摘要】 提出了一种可以改善反射式彩色液晶显示视角的微锥结构膜。模拟计算结果表明，当光从微锥的底部人射时，该膜起到准直作用，当光从微锥的顶部入射时，该膜起到散射作用。利用微锥膜可显著改善反射式干涉滤光膜的视角依赖性。由于微锥膜的作用不依赖了液晶盒结构，所以，可对多种结构的反射式彩色液晶显示有效。更多还原

【Abstract】 A micro-cone-structure film was proposed to improve the viewing angle of reflectivecolor LCDs both in chromaticity and brightness. The simulation results show that the filmworks as a collimating layer when the light incident from bottom side of cone and as ascattering layer while the light incident from tip side. The viewing angle dependence ofreflective interference color filters (RICF) is weaken dramatically by including such a film.The film is not only useful to RICF, but also to most of reflective color LCD modes.更多还原
