P‐44: Adaptive Threshold Overdriving Scheme for Improved LCD‐TV Noise Performance

This paper proposes an adaptive threshold overdriving algorithm to avoid exacerbating noise problems in LCD-TVs. In conventional LCD-TVs, video image noise is boosted by the timing controller's overdrive function, resulting in harsh noise as perceived by the human visual system. Various gray data and noise levels have been analyzed, and the conditions which generate the boosted noise have been extracted and applied to a new algorithm to adjust overdrive threshold criteria according to the input images. The new overdriving scheme shows greatly improved noise performance compared to conventional fixed threshold schemes.
