Abstract

We propose an optical configuration to achieve symmetric and high contrast ratio (CR) in three-dimensional (3D) polarization switching (PS) displays. This optical configuration is accomplished using three retardation films and a λ/2 retardation switching panel. Typically, λ/2 retardation switching in the PS panels has an unanticipated asymmetric CR on the left- and right-hand side of 3D glasses because of the wavelength-dependent phase dispersion. To overcome this problem, we designed an optical configuration and applied it to the electrically controlled birefringence (ECB) cell. As a result, symmetric and high CRs are obtained for the 3D PS display.
