In the proposed method, the degree of overdriving is not constant over the whole image.

The slow response of current LCD only contributes to 30\% of the motion blur, while the hold-type rendering mode of LCD contributes to 70\%. Therefore, fast LCD such as OCB itself does not significantly reduce motion blur. Fast LCD, on the other hand, is critical to the proposed three solutions of hold-type blur to avoid the ghosting artifact.

Particularly, the wide-viewing-angle property and fast gray-to-gray response time of S-IPS LCDs are both necessary requirements for family and individual use for LCD TVs. Given these benefits and other advantages S-IPS provides, LG.Philips LCD has developed high-performance S-IPS LCDs for TV, which have now become competitive with plasma-display panels (PDPs), in addition to other modes of LCD TVs as well as CRTs. This article will discuss why S-IPS technology is the leading choice for LCD-TV applications.}, citeseerurl = {95}, comment = {0}, owner = {adam}, pdf = {/home/adam/Article/95.pdf}, timestamp = {2006.08.17} } @PROCEEDINGS{Vesa2005, title = {Flat Panel Display Measurements Standard V2.0}, year = {2005}, publisher = {VESA}, month = {May}, citeseerurl = {06}, comment = {1}, institution = {Video Electronics Standards Association}, owner = {adam}, pdf = {/home/adam/Article/06.pdf}, timestamp = {2005.01.09} } @PROCEEDINGS{uitbt500-2002, title = {Recommandation UIT-R BT.500-11}, year = {2002}, citeseerurl = {54}, comment = {0}, owner = {adam}, pdf = {/home/adam/Article/54.pdf}, timestamp = {2005.01.09} } @comment{jabref-meta: selector_journal:European Signal Processing Conf erence;IDW Digest of Technical Papers;IEEE International Conference on Consumer Electronics;IEEE International Conference on Image Processin g;IMID/IDMC Digest of Technical Papers;Journal of the Korean Physical Society;Journal of the SID;Proceedings of SPIE-IS\\&T Electro,ics Imag ing;Proceedings of the International Conference on VLSI Design;SID Sym posium Digest of Technical Papers;} @comment{jabref-meta: selector_author:A.
