Abstract
Official abstract text for this publication.
A blue-phase liquid crystal panel is described which includes a first substrate, a second substrate, a blue-phase liquid crystal layer between the first substrate and the second substrate; a first electrode located on one surface of the first substrate, a first substrate coupling film located on another surface of the first substrate; a second electrode located on one surface of the second substrate; the first electrode and the second electrode forming a vertical electric field; the first substrate coupling film converting the direct front light of the backlight module into slant front light having a predetermined angle with the perpendicular electric field direction. By generating a vertical electric field, the liquid crystal panel enhances the electric field strength and uniformity of the blue-phase liquid crystal layer, and by changing the angle of light of the backlight source entering the liquid crystal cell, subjecting the incident light to phase retard, thus lowering the operating voltages of the blue-phase liquid crystal panel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A blue-phase liquid crystal panel, comprising: a first substrate; a second substrate; a blue-phase liquid crystal layer between the first substrate and the second substrate, the first substrate being disposed opposite to the second substrate; a first electrode located on one surface of the first substrate facing the blue-phase liquid crystal layer; a first polarizer and a first substrate coupling film located on another surface of the first sub…
