P-87: Multi-Channel Liquid Crystal Retardation Measurement Technology

We propose a novel real‐time multi‐channel retardation measurement method for the quality control of liquid crystal panels, for example cell gap and compensation film. We combine spectroscopic ellipsometry method with the hyperspectral imaging spectrograph to realize multi‐channel measurement. In pa...

Description
Summary:We propose a novel real‐time multi‐channel retardation measurement method for the quality control of liquid crystal panels, for example cell gap and compensation film. We combine spectroscopic ellipsometry method with the hyperspectral imaging spectrograph to realize multi‐channel measurement. In particular, polarizing beam splitter is used in spectroscopic ellipsometry method to replace the analyzer for speeding up measurement.
