It has been reported recently that conventional methods for measuring the contrast ratio of display devices using small dark spots provide inaccurate data. In this paper, we describe an experimental method for reliable measurements of the small spot contrast ratio, based on a collimated probe that minimizes the signal contamination to less than 10− 4 of the bright eld. Applications to veiling glare measurements and electronic crosstalk characterization are presented.
