摘要

A method to reduce the transmittance nonuniformity caused by comb electrode spacing variations of in-plane switching mode thin-film transistor liquid-crystal displays is proposed. The method is based on the compensation of the effect of the comb electrode spacing variations with effective driving voltage variation via feed-through voltage in the thin-film transistor addressing. The conditions for this compensation were analyzed theoretically taking into account gate delay (recharging) effects. It was observed that the common dc driving was superior to the common inversion driving in terms of compensation efficiency. An alternative driving method was proposed to enhance the compensation in common inversion driving.
