Abstract
This paper reviews the recent trends on super-patterned vertical alignment
(S-PVA) and fringe-field switching (FFS) technologies for liquid crystal display
(LCD)-television (TV) applications. For PVA mode, Samsung originally announced
S-PVA technology in 2004 to enhance off-axis viewing quality of conventional
PVA mode. S-PVA is a new technology which enables screen quality advantages
over super-in plane switching (S-IPS) and multi-domain VA (MVA), including
high transmittance, $>$2300:1
contrast ratio, and wide viewing angle with no off-axis image inversion. This
paper explores and updates Samsung's latest developments toward its goal of
ultimate LCD-TV performance. For FFS mode, the technology appeared in 1998
by HYDIS and now it has been commercialized in all kinds of display applications,
implying its technical importance. This paper reviews recent developments
and performance of LCD-TV using the FFS mode based on published papers and
our knowledge.
