多元非對稱微透鏡陣列光控制薄膜(MAMA-LCF),是利用不同旋轉角度之非對稱微透鏡將不同角度之入射光線集中,並控制其反射光角度來增加反射式顯示器之亮度與對比度。適當設計與排列光控制薄膜之多元非對稱微透鏡陣列,可以提升亮度至氣化鎂標準白的五倍,應用於彩色STN液晶顯示器,對比度達到12: 1;應用於PDLC,對比度提升10倍達到11.5: 1,或搭配贍固醇液晶顯示器使用,對比度可提升至傳統的9倍。且此元件用於液晶顯示器沒有表面漫射、雲彩花紋(Moiré pattern)或是視差等現象。
A multidirectional asymmetrical microlens array light control film (MAMA-LCF) which can direct light incident from multiple directions collectively for viewing is demonstrated in achieving much enhanced with brightness in reflective color STN-LCDs、PDLC、Ch-LCD. Through optimized designs and optical alignments, the MAMA-LCF which is constructed with asymmetrical microlens arrays, leads to a~5x gain in brightness over the MgO standard white and 12: 1 contrast ratio for color STN-LCDs; 10x gain and 11.5: 1 contrast ratio for PDLC; and 9x gain over the conventional Ch-LCD. In each display, the light control film does not induce visible surface diffusion, moiré patterns and parallax.
