Abstract: | The optimised structures of blue-phase liquid crystal display (BPLCD) with various protrusions were discussed in this article. The voltage-dependent transmittances for the cell with four protrusion shapes, wall-shaped electrode, trapezoid electrode, double penetration electrode and elliptical electrode, are simulated. The electrode gap and width and protrusion height’s effects on the optimised cell gap and the corresponding operating voltage are calculated. The optimised cell has the lowest operating voltage and relative high transmittance. The results are significant on design BPLCD with low operating voltage. |
