Schematic diagram in the OLD mode: (a) cross-sectional structure of the OLD mode. (b) The structure of the top and bottom electrodes (top view). (c) LC behavior under applied voltage field on state (side and top views).
Poincare sphere representation of the optical principle of the OLD mode: (a) the path of light passing through the retardation film at an optical axis of 45°. (b) The path of light passing through the LC layer. (c) The path of light passing through the retardation film at an optical axis of 135°.
Microscopic images showing the LC distribution due to an electric field applied to the proposed doughnut-shaped slitted electrode.
(a) The simulated and measured optical transmittance curves as a function of electric field for the OLD and the PVA modes. The inset photograph images show the bright states of the fabricated samples. (b) Response time of the OLD cell.
