Title:
PARAMETERS OPTIMIZATION FOR REFLECTIVE BTN DISPLAY USING THE POINCARE SPHERE METHOD
Document Type and Number:
WIPO Patent Application WO2000066682
Kind Code:
B1
Abstract:
Disclosed is a transparent upper substrate that faces a lower parallel sustrate with a polarizing sheet attached to the upper surface of the upper substrate. A first electrode is formed on the lower surface of the upper substrate and an upper alignment layer is formed on the first electrode. A light reflective second electrode is formed on the lower substrate and a lower alignment layer is formed on the second electrode. A ferroelectric liquid crystal layer is interposed between the upper and lower substrates with the retardation of the liquid crystal layer, the cone tilt angle of liquid crystal molecules, the polarizing direction of the polarizing sheet, and the alignment direction controllable to achieve gray scales.
