A computational model of a nematic liquid crystal device incorporating hydrodynamic backflow effects and active-matrix drive methods is introduced. The model is applied to assess the effect of overdrive addressing on the optical response. We find that backflow effects are non-negligible and that overdrive methods can be efficiently optimized to give major improvements in response times. Preliminary experimental results on the transient optical response of test devices are also reported and excellent agreement with the simulated response is obtained.
