A hybrid aligned nematic reflective liquid crystal display driven by a fringe-field

Autor: Tae Bong Jung, Yong-Bae Kim, Hyun Chol Choi, Seung Hee Lee

Publikováno v: Liquid Crystals. 31:1393-1397

We have designed a novel reflective nematic liquid crystal (LC) cell driven by a fringe electric field, in which the LCs are hybrid aligned in the initial state. Due to the hybrid alignment of the LC, the effective retardation value of the cell is gr

Publikováno v: SPIE Proceedings.

Printing small vias with tight pitches is becoming very challenging and consequently, different techniques are explored to achieve a robust and stable process. These techniques include reverse tone imaging (RTI) process, source optimization, mask tra
