Paper Abstract

The current status of optical metrology of LCD (Liquid Crystal Display) is reviewed in general and shortcomings of characterization of the visual performance of LCD-screens when high visual fidelity is a prime issue are described. We introduce instrumentation, procedures and evaluations for assessment of the visual properties of LCD-TV screens as a solid basis for a clear and objective rating of their performance. Identification of visual artifacts, color and gray-scale fidelity over the complete viewing-cone and under realistic ambient illumination as well as balanced response times between gray-levels are topics of this paper. A novel approach for scanning of the viewing-directions with simultaneous acquisition of 9 spectra is introduced as a solution for the dilemma of speed of measurement and colorimetric precision.
