| Abstract: | Abstract— A 32‐in. IPS‐LCD with a significantly wide‐viewing‐angle performance has been developed using a new optical compensation method. It provides a contrast ratio of over 80:1 at all viewing angles, which enhances its color saturation at oblique angles. According to our study, it is important to shorten the path of the optical compensation in the Poincaré sphere. We have found an effective method using two retardation films, one with an Nz value larger than 0.5 and one with a value smaller than 0.5. |
