Dynamic modulation transfer function: a method to characterize the temporal performance of liquid-crystal displays

Opt Lett. 2008 Mar 15;33(6):533-5. doi: 10.1364/ol.33.000533.

Abstract

A method to measure the dynamic modulation transfer function (DMTF) of a liquid-crystal display (LCD) is proposed to characterize its performance when rendering motion images. The method includes a measurement system to capture the temporal luminance variation of a LCD while using a well-designed input data sequence and a simulation model based on smooth pursuit eye tracking and temporal light integration at the human retina. It predicts the perceived performance of a moving sine wave pattern on a LCD and subsequently calculates the DMTF. With this approach, several technologies to reduce motion blur were evaluated and discussed.
