Abstract

A new pixel circuit for in-plane switching blue-phase liquid crystal displays (IPS BPLCDs) is developed. The dual-coupling method enables the proposed circuit to generate twice the maximum output voltage of source driver integrated circuits (ICs) for the BPLC with a simple structure, so the achievable transmittance is about four times that of the BPLC that is simply driven using practical source driver ICs. A 10.1-in prototype IPS BPLC panel (720 × 360) and simulation results demonstrate the feasibility of the proposed circuit for practical BPLCD applications, and the tone rendering distortion index is as low as 0.11.
