This paper presents an experimental demonstration of a visible light communications link with an light emitting diode and a low-bandwidth organic photodetector as transmitter and receiver, respectively, that achieves sub
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 ang
