A visualization tool for evaluating angular-dependent colorimetric performance of LCD

Abstract

We have developed an interactive visualization tool that emulates the visual effect of an LCD when viewed at a specific angle such that the user can easily assess its colorimetric performance such as color shift, saturation degradation, and contrast/luminance reduction. The target LCD has to be characterized to generate its colorimetric parameters at different viewing angles. The proposed tool then calculates the resulting image by table-lookup and interpolation. This tool is particularly useful when evaluating multiple LCDs simultaneously or remotely.
