Pixel structure for higher optical efficiency in the patterned vertical alignment LC mode

Abstract

In this paper, we propose new pixel structures for high transmittance in the patterned vertical alignment mode. We formed the protrusion or the slit on the top substrate to reduce the width of disclination lines at the domain boundaries.

High transmittance pixel structure for the multidomain vertical alignment mode

“…Recently, PVA mode with micro-patterned electrodes was proposed to obtain high transmittance [9][10][11]. In addition, forming micro-slit electrode on the top substrate of the PVA mode with micro-patterned electrodes can further improve the transmittance [12,13]. However, the transmittance is decreased at the pixel boundaries because the angle between LCs and the TA of polarizers is less than 45°.…”
