Viewing angle performance in in-plane switching liquid
crystal displays (IPS-LCDs) has been greatly improved, using two
technologies. One is optical compensation technology using a biaxial
film. The other is a newly developed IPS-Pro cell structure with
higher transmission efficiency. These technologies are successfully
introduced into the fabrication of 32-in. IPS-LCDs with a minimum
contrast ratio over three times that of conventional IPS-LCDs and
with color saturation (area ratio to NTSC at CIE1931 xy chromaticity
coordinates) of more than 70% at almost all viewing angles.
