The obtained results indicate that under the non-memory state, the surface anchoring energy of the substrate, the operation voltage of the pi cell and the transition time of the pi cell from the splay state to the asymmetrical splay state decrease with increasing silica nanoparticle concentrations. When a high voltage pulse is exerted to the silica nanoparticle doped pi cell, the doped silica nanoparticle accumulate on the substrate surface and thus creates Twisted-Pi state, overcoming the difficult transformation problem of the conventional pi cell.
