摘　　要：本文介绍了一种低功耗全彩透反射型液晶显示器。该液晶显示器利用高双折射率(Δn)胆甾相液晶(Ch-LC),并在透射区域的顶部设置了一块影像增强反射层(IER)。高双折射率(Δn)胆甾相液晶能够反射宽波段的光而显示白色图像。采用传统的彩色滤光膜方法就可以显示全彩色图像。此外,在透射区顶部的IER为透射光和反射光提供了相似的光路。在任何环境下,透射区与反射区总是显示相同的图像颜色,因而大大提高了全彩色透反射型胆甾相液晶显示器显示图像的质量。A full color transflective liquid crystal display with low power consumption is demonstrated by using high?膎 cholesteric liquid crystal (Ch-LC) as an LC layer and building an image-enhanced reflector (IER) on the top of the transmissive region. The high 膎 Ch-LC can reflect wide band wavelength to display white image. With conventional color filter process, a full color image can be shown. Additionally, an IER on the top of the transmissive region provides the similar paths for both transmissive and reflective light.The two regions can always display same image color in any ambience, thus to greatly improve the image quality of the full color transflective cholesteric liquid crystal display.
