A method is described for estimating the viewing angle characteristics of an LCD on the basis of the overall quality of the pictures displayed. The factors affecting picture quality change when the angle at which an LCD is observed changes. Changes in color, maximum luminance, and minimum luminance were found to have the largest effects on picture quality. Individual picture quality was subjectively evaluated after each of these factors was changed. The estimated impairments for three the factors were integrated using an impairment summation model to give the estimated overall picture quality. The observation angle corresponding to the acceptable limit of overall picture quality was found to be similar to that obtained by direct measurement. The proposed estimation method is thus effective for estimating the viewing angle characteristic. It is, though, suggested that the affects of the three factors on picture quality need to be studied in detail from the viewpoint of independence.
