Novel pixel circuit to enlarge operation voltage for blue-phase liquid crystal displays
A novel pixel circuit composed of four thin-film transistors (TFTs) and two capacitors is proposed for blue-phase liquid crystal displays (BPLCDs). The capacitive coupling method can enlarge the voltage across BPLC, and the pre-charging method shortens the charging time effectively. Four voltage levels of VBIAS are established for attaining desired voltage, when VDATA supplied by practical source driver integrated circuits (ICs) cannot reach maximum transmittance of BPLC. Simulated results based on the specification of full high-definition BPLCDs with frame rate of 180 Hz confirm that the proposed pixel circuit can enlarge the maximum operation voltage from 15 V to 30 V.
