Birefringent Contrast Enhancer (PDF, 0.20 MB)
Perfecting the image with BCE
JDSU continues its tradition of providing innovative optical components to the display industry with the introduction of its Birefringent Contrast Enhancer (BCE). JDSU’s BCE has been optimized for maximum performance when used in LCOS engine architectures based on wire grid polarizers (WGP). Using proprietary birefringent film technology, the BCE enables 5 to 10x contrast improvement with unprecedented uniformity.
JDSU’s unique ability to tailor both the a-plate retardance (in plane) and the c-plate retardance (out of plane) allows the freedom to optimize the system performance as never before. This independent control allows simultaneous compensation for unwanted polarization effects introduced by the pre-tilt of the liquid crystal microdisplay and the cone angle of the light.
Using a combination of proprietary thin film coatings and Hybrid Liquid Crystal material, JDSU is able to provide compensating retarders which exhibit outstanding reliability and durability. JDSU’s BCE exhibits particular advantage at shorter wavelengths toward the blue and at high light fluxes and elevated temperatures (up to 120°C) where competing products typically struggle or fail.
