A Novel Hole Induced Vertical Alignment LC Mode with Superior Transmittance

摘要

A novel pixel design for vertical alignment LCD with superior transmittance is developed in this work. The new liquid crystal mode, named as Hole Induced Vertical Alignment mode (Hi-VA), uses a via hole of an organic layer on TFT substrate to achieve multi domain alignment. Compare to conventional design, the Hi-VA mode has up to the transmittance of 135% with the contrast ratio of 2000:1. Moreover, the new structure is free from the ITO patterning or protrusion on color filter side, which makes the fabrication process simple and low cost.
