Abstract
Color filters used in white light-emitting diode (LED) displays are composed of alternating high-index ZnS and metallic Ag layers. Such a filter has low polarization or angle effect. If this filter is used in the case of oblique incident or large cone angles, the wavelength shift can be reduced significantly, and good filter characteristics can be maintained. Therefore, these filters can meet the needs of white LED color displays.
