Abstract

We present a single-cell gap-transflective liquid crystal display (LCD) characterized by a π cell having bulk-type liquid crystal (LC) bistability and an optical film configuration. The π cell has two stable states, which are a twisted and a nontwisted LC state. We used the twisted LC state for the reflective part connected with nonpatterned electrodes, producing a vertical field in the proposed transflective LCD. Also the nontwisted LC state was for the transmissive part with interdigitated patterned electrodes driving an in-plane field in the device. The simulated and experimental results show good electro-optical characteristics in both the reflective and transmissive parts.

摘要

我们展示了一种单细胞间隙透反射液晶显示器（LCD），其特征在于具有体相型液晶（LC）双稳态的π型盒和光学薄膜结构。该π型盒具有两种稳定状态，即扭曲液晶态和非扭曲液晶态。我们将扭曲液晶态用于与无图案电极相连的反射部分，在所提出的透反射LCD中产生垂直场。同样，非扭曲液晶态用于具有叉指图案电极的透射部分，以驱动器件中的面内场。模拟和实验结果表明，反射部分和透射部分均具有良好的电光特性。
