7.3: Advanced Level Adaptive Overdrive (ALAO) Method Applicable to Full HD‐LCTVs

Abstract

Abstract In this paper, we report on the development of an advanced level‐adaptive overdrive (ALAO)method applicable to full HD‐LCTVs, which not only reduced the gray level response time to less than one fourth, but also improved S/N for still pictures by 10 dB and reduced the circuit cost for the LAO method to almost half that of a conventional LAO circuit. We applied the ALAO method to a full‐HDLC projector with 1.84 M pixels and obtained high full‐HD motion picture qualities.
