Abstract

This work develops a pixel circuit for in-plane switching blue-phase liquid crystal displays (IPS BPLCDs) integrated with amorphous indium-gallium-zinc-oxide thin-film-transistors (a-IGZO TFTs). The proposed circuit enlarges the range of operation voltage of BPLC by selecting different bias voltage signals to achieve maximum transmittance of BPLCs. Polarity inversion is also combined with the source follower structure. Simulation results show that the proposed circuit increases the operation voltage to -50 V to 50 V and the error voltages over the entire range of operation voltage are all below 1.2 V demonstrating the feasibility and the reliability of the proposed circuit for practical BPLCD applications.
