ABSTRACT:
A contrast compensator for improving the panel contrast of liquid crystal (LC) microdisplays having a high-order waveplate configured as an O-plate and supporting a thin film transistor layer is provided. The contrast compensator includes a counter high-order waveplate configured as an O-plate, which has a birefringence opposite in sign to a birefringence of the thin film transistor substrate.
