Abstract

We propose a novel pixel circuit using source-follower structure to be independent of frequency effect of blue-phase liquid crystal displays (BPLCDs). Simulation results indicated that required gray-level-voltages across the BPLC could be achieved accurately when a proper threshold voltage of the driving TFT was chosen. We also successfully fabricated a 12.7-inch prototype BPLCD using the proposed pixel circuit driven with a field-sequential-color method of 240 Hz.
