Abstract

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