Backlighting lightpipes for display applications |
摘要 |
This invention discloses improved lightpipes for backlighting applications in liquid crystal display devices. The lightpipes comprise transparent polymers with scattering centers. A preferred composition for such lightpipes comprises a cycloolefin polymer containing scattering centers from suitable elastomers and inorganic fillers. The inventive lightpipes offer superior scattering efficiency as well as spatial uniformity of scattering and uniformity of scattering across a wide wavelength range.
