Rubbing angle effect on in-plane switching liquid crystal displays

The rubbing angle effect on transmissive in-plane switching liquid crystal displays is analysed by the Jones matrix method. Simulation results show that the optimum rubbing angle is around 30 degrees-40 degrees; the cell gap/birefringence product (d Delta n) is about 0.33 mu m. Increasing the rubbing angle can shorten the rise time and enlarge the grey scale voltage intervals. The optical characteristics are similar in two cells with different rubbing angles. These effects are particularly attractive for liquid crystal TV applications.
